Subject: [PATCH 001/112] fix: pass OPENCODE_API_KEY env var when syncing
 opencode-go models

discoverOpencodeGoModels() spawns 'opencode models opencode --refresh' but
never passed the saved API key as OPENCODE_API_KEY. The opencode CLI's
internal OpencodePlugin checks this env var to decide whether to show
paid models; without it, only free (cost.input === 0) models appear.

Now threads the apiKey from auth storage through to the spawned process
environment, so the CLI sees the user's Go subscription and returns the
full model catalog including paid models like Claude, GPT-5.x, Gemini, etc.

Callers in serve.ts, daemon.ts, and dashboard.ts all updated to read
the key from dashboardAuthStorage and pass it to refreshOpencodeGoModels.
syncStartupModels reads from authStorage in StartupSyncOptions.

Subject: [PATCH 002/112] fix: strip provider prefix from opencode-go model IDs

normalizeOpencodeGoModel was prefixing model IDs with 'opencode-go/'
(e.g. 'opencode-go/deepseek-v4-flash'), but the Pi SDK sends the model
id field as the model name in API requests. The OpenCode API expects
bare model names (e.g. 'deepseek-v4-flash'), not prefixed ones.

Now strips the 'opencode/' or 'opencode-go/' prefix entirely so the
registered model ID matches what the API expects.

+Fix opencode-go model sync: pass API key to CLI and strip provider prefix from model IDs
+
+Two bugs when using OpenCode Go as a provider:
+
+1. **Model discovery only returned free models** — the saved Go API key was never passed as `OPENCODE_API_KEY` to the spawned `opencode models opencode --refresh` process. The CLI's internal plugin checks this env var and, when absent, disables all paid models (those with `cost.input > 0`). Only 20 free models appeared instead of all 67.
+
+2. **API requests failed with 401** — `normalizeOpencodeGoModel` was registering models with prefixed IDs like `opencode-go/deepseek-v4-flash`. The Pi SDK sends `model.id` verbatim in API requests; the OpenCode API expects bare model names (e.g. `deepseek-v4-flash`). The prefix is now stripped during normalization.
+
+Also deduplicates models when the CLI emits both `opencode/foo` and `opencode-go/foo` for the same model, guards against empty model IDs, and refactors the duplicated `onApiKeySaved` handler into a shared `handleOpencodeGoApiKeySaved` helper.
+
+After this change, users must re-select their opencode-go model in Settings because model IDs have changed from prefixed to bare names.

+# feat: Node editor visual redesign + success/failure edge authoring
+
+## Summary
+
+Upgrade the workflow node editor's authoring experience: redesign graph nodes from small icon+label pills into larger card-style nodes with kind accent colors and config summaries; generalize edge-condition authoring so success/failure is selectable on regular edges (today only step-review edges are editable) with distinct visual styling; and round out editor power/polish — safe node/edge deletion, proper dialogs replacing `window.prompt`/`window.confirm`, inline rename/description, dirty-state guard, auto-layout, and a real empty/onboarding state. UI/authoring layer only — no engine, IR-schema, or compiler-semantics changes.
+
+---
+
+## Problem Frame
+
+The editor (`packages/dashboard/app/components/WorkflowNodeEditor.tsx`, built on `@xyflow/react`) has grown to 13 editor node kinds with swimlane columns and an edge inspector, but the authoring surface lags the capability underneath:
+
+- **Nodes are unreadable at a glance.** `NodeShell` (`packages/dashboard/app/components/nodes/WorkflowNodeTypes.tsx`) renders icon + label + tiny badges. A prompt node configured with a model, an agent, or a CLI command looks identical to an unconfigured one; users must click every node to see what it does.
+- **Failure edges exist everywhere except the editor.** The IR accepts any `edge.condition` (`parseWorkflowIr` never validates condition values), and the graph executor natively traverses `failure` edges (`shouldTraverseEdge`, `packages/engine/src/workflow-graph-executor.ts:385-392`). But `onConnect` hardcodes every new edge to `success`, and the edge inspector only offers condition controls when the source node is `step-review`. There is no way to author the branching the engine already supports.
+- **Authoring chrome is crude.** `window.prompt` for workflow names, `window.confirm` for deletes, no keyboard deletion, no dirty tracking (switching workflows silently discards edits), no auto-layout, and a bare "Select or create a workflow" empty state.
+
+---
+
+## Scope Boundaries
+
+### In scope
+- Card-style node redesign with config summaries and kind accent colors.
+- Success/failure edge-condition authoring on regular edges, with distinct edge styling and an honest "interpreter-only" presentation when branching makes the graph non-compilable to the linear step engine.
+- Deletion UX (keyboard + buttons) with explicit cascade semantics.
+- Dialogs, inline rename/description, dirty-state guard, auto-layout, empty/onboarding state.
+
+### Deferred to Follow-Up Work
+- Undo/redo history for the canvas.
+- Workflow import/export, versioning, templates gallery.
+- Localizing edge condition labels (kept as canonical IR tokens — see KTD-8).
+- Auto-layout inside `foreach` template groups beyond the existing seeded row.
+
+### Outside this product's identity
+- Changing edge/branching **execution** semantics. The graph interpreter, `parseWorkflowIr` graph validation, and the linear-step compiler keep their current behavior; this plan only lets users author what they already support and presents their limits honestly.
+
+---
+
+## Requirements
+
+**Visual**
+- R1 — Graph nodes render as card-style nodes: kind accent color, icon, label, and a config-summary line (model/agent/skill/CLI for prompt nodes; script name; gate mode; hold release; join mode; parser; review type), with a defined header-overflow priority and truncation; existing badges and error badges preserved.
+- R2 — Success, failure, and rework edges are distinguishable by at least two independent visual channels: the condition label is always rendered, and failure edges use a distinct dash pattern from success edges; color (token-only, both themes) is a third channel, never the only one.
+
+**Edge authoring**
+- R3 — A user can set a regular edge's condition to `success` or `failure` from the edge inspector via a native `<select>` in the inspector's natural tab order; new edges still default to `success`. The control appears only for source-node kinds where failure is meaningful (see KTD-2).
+- R4 — A node can carry parallel `success` and `failure` edges to different targets (forward of the source — see KTD-9); both survive save/load round-trip.
+- R5 — When a saved graph fails the linear-step compile because of branching, the editor presents an informational "runs on the graph interpreter only" state rather than an error-toned failure banner; genuinely invalid graphs — including those rejected by `parseWorkflowIr`'s graph validation at save (illegal cycles, disconnected nodes) — still error.
+
+**Editor UX**
+- R6 — Deleting a node (button or keyboard) cascades its incident edges; deleting a `foreach` group cascades its template children and intra-template edges; `start`/`end` remain non-deletable; no automatic edge bridging. After keyboard deletion, focus moves to the canvas container.
+- R7 — Workflow create uses a proper named dialog with inline validation (empty/duplicate names) and focus return to its trigger on close; workflow delete uses `ConfirmDialog`; workflow name and description are editable inline in the editor; unsaved changes prompt a discard confirmation on workflow switch or editor close (all dismissal paths, including Escape).
+- R8 — An auto-layout action arranges nodes left-to-right by graph order; in v2 workflows it preserves each node's column (y stays within its band, staggering x when a band row fills); in v1 it lays out freely; `foreach` template children are left untouched.
+- R9 — The no-workflow and trivial-graph (start→end only, user-owned) states show onboarding guidance with clear calls to action.
+
+**Cross-cutting**
+- R10 — Every new control (edge condition selector, delete buttons, keyboard delete, rename/description, auto-layout) is inert for built-in workflows; all new user-facing strings go through i18next.
+
+---
+
+## Key Technical Decisions
+
+- KTD-1 — **Failure-edge authoring is a UI-gating change, not an engine change.** `updateSelectedEdge` already handles arbitrary conditions and `flowEdgeToIr`/`irEdgeToFlow` already round-trip `condition`; `parseWorkflowIr` accepts `failure` as a condition value; the graph executor traverses it. The work is widening the inspector beyond step-review-sourced edges and styling the result. No changes under `packages/engine/` or to `packages/core/src/workflow-ir.ts`. Note: `parseWorkflowIr` still runs its graph-shape validation on save (cycle/disconnection rules) — see KTD-9 for the author-time guard.
+- KTD-2 — **Failure option gated by source-node kind allowlist.** Offer success/failure on edges sourced from `prompt`, `script`, `gate`, `code`, and `foreach` (kinds whose execution genuinely emits failure outcomes). `step-review` edges keep the verdict/rework controls; `start`, `split`, `hold`, `merge`, `join`, and `parse-steps` sources don't get the selector (split fan-out is success-semantics by design; hold releases aren't failures; parse-steps failures route via its dedicated `outcome:parse-error` condition). Rationale: prevents authoring graphs that are neither compilable nor coherently interpretable, per flow analysis.
+- KTD-3 — **Conditioned edges are appended directly, bypassing `addEdge`.** React Flow's `addEdge` dedupes via `connectionExists`, which compares only source/target/handles and ignores `id` — a custom id alone would NOT permit the core "success edge + failure edge from the same node" case. `onConnect` constructs the edge with an explicit unique id (mirroring the `newNodeId` pattern) and appends via `setEdges((eds) => [...eds, edge])`, reimplementing the basic source/target sanity checks `addEdge` provided.
+- KTD-4 — **Compile-failure presentation splits "interpreter-only" from "broken," keyed on the shared message suffix.** `validateLinearity` emits more than one interpreter-deferred rejection (branch fan-out and off-main-path nodes); both carry the suffix `require the workflow interpreter (deferred)`. Compile errors matching that suffix render an info-tone banner; other compile errors keep the warning treatment. The banner states (1) the workflow still runs, (2) why: branching can't compile to the linear step engine — using the info token, not the warning token. Save-time `parseWorkflowIr` rejections (cycles, disconnected nodes) are a separate, earlier layer and remain hard errors with the existing node-attribution treatment. The compiler itself is untouched; the string coupling is a named risk.
+- KTD-5 — **Hand-rolled auto-layout, no new dependency.** No dagre/elk anywhere in the repo, and the column-band constraint (node y determines its column via `columnForY`/`strictColumnForY`) makes generic rank-based layout actively harmful. Layout = topological layering from `start` for x, and y preserved per column band (v2) or assigned by within-layer index (v1). When same-layer/same-band nodes exceed the band's vertical capacity, overflow staggers horizontally (extra x offset) rather than escaping the band. `foreach` group interiors are skipped (children already seed in a row; `extent: "parent"` clamps them).
+- KTD-6 — **Config summaries derive from a pure helper with raw-id fallback.** A `nodeConfigSummary(data, catalogs)` helper (testable without React Flow) maps `config` → summary text. Models/agents/skills catalogs are prefetched once on editor open so summaries show names; until loaded (or on fetch failure) summaries show raw ids — never blank.
+- KTD-7 — **Dialogs reuse existing primitives; no new component file.** Delete and discard-confirm use the existing `useConfirm`/`ConfirmDialog` (provider already mounted app-wide). The create-workflow name dialog is a local component inside `WorkflowNodeEditor.tsx` built on the shared `.modal` primitives (precedent: `NewTaskModal`); extraction to a shared text-input dialog waits for a second consumer. Rename/description use inline editing (KTD-10), so no rename modal exists.
+- KTD-8 — **Edge labels stay canonical IR tokens (`success`/`failure`/verdicts), not localized.** They name IR vocabulary, match the current verbatim display of conditions, and keep mapping-layer label logic (`shortConditionLabel`) locale-free. Surrounding inspector chrome is localized as usual.
+- KTD-9 — **Author-time guard against failure back-edges.** `validateNoIllegalCycles` exempts only `rework` edges; a failure edge targeting an ancestor forms an illegal cycle and would be rejected at save with a confusing server error. The editor blocks connecting an edge whose target is an ancestor of its source (simple reachability walk at connect time) with an explanatory toast, keeping the first-class failure-edge UX from dead-ending on the parse layer. Server validation remains authoritative.
+- KTD-10 — **Rename is inline, not modal.** The active workflow's name renders in the canvas header strip; clicking it activates an inline input (Enter commits, Escape cancels, blur commits); the description is an adjacent field in the same strip. This avoids a second modal and keeps the create dialog (KTD-7) the only name modal.

+   unit; children untouched             untouched (parent-relative)
+
+Invariant: layout never changes any node's column assignment and
+never produces unplaced nodes (which would block save).
+```
+
+*Directional guidance, not implementation specification.*
+

+
+## Implementation Units
+
+### U1. Card-style node redesign
+
+**Goal:** Replace the pill `NodeShell` with a larger card layout showing kind accent, icon, label, badges, and a config-summary line.
+**Requirements:** R1, R10.
+**Dependencies:** none. **Consumed by:** U5 (card max-width / foreach group constants must be finalized here and exported as named constants so U5 imports them rather than duplicating numbers).
+**Files:**
+- `packages/dashboard/app/components/nodes/WorkflowNodeTypes.tsx` (modify) — card layout in `NodeShell`; summary line; keep testids and `WorkflowNodeErrorBadge`.
+- `packages/dashboard/app/components/nodes/node-summary.ts` (new) — pure `nodeConfigSummary(data, catalogs)` helper.
+- `packages/dashboard/app/components/nodes/__tests__/node-summary.test.ts` (new).
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — prefetch models/agents/skills on open; pass catalog name-lookup into node data or context.
+- `packages/dashboard/app/components/workflow-flow-mapping.ts` (modify) — exported card-dimension constants; grow `FOREACH_GROUP_WIDTH/HEIGHT` + child offsets if needed for card fit.
+- `packages/dashboard/app/components/WorkflowNodeEditor.css` (modify) — card classes, per-kind accent tokens (`color-mix` over existing status/accent tokens), truncation, max card width.
+**Approach:** Card = header row (icon, label, badges) + summary row. Header overflow priority: icon fixed-width; label flex-shrinks first (ellipsis at a defined max-width); badges `flex-shrink: 0`, flush right; the error badge always holds the rightmost slot; the summary row truncates independently. Summary derivation per executor mode: model → `provider/modelId`, agent/skill → name from prefetched catalog with raw-id fallback, cli → truncated command or script name, plus gate mode, hold release, join mode, parser, review type. Foreach group rendering unchanged except header polish; keep children inside the group box. Token-only CSS; `--duration-*` tokens for any animation.
+**Patterns to follow:** existing `wf-node-*` classes; `docs/dashboard-guide.md` styling guide (tokens, button-freeze, `color-mix` precedent at `WorkflowNodeEditor.css:337`).
+**Test scenarios:**
+- `nodeConfigSummary`: model-executor prompt → `provider/modelId`; agent executor with catalog loaded → agent name; catalog missing → raw id; cli command → truncated command; script node → script name; gate node → gate-mode text; unconfigured prompt → "not configured" text; hold/join/parse-steps/step-review summaries.
+- Rendered card shows summary line for a configured prompt node (jsdom node rendering works; assert via testid).
+- Foreach child card fits group: constants test asserting child offsets + card max width ≤ group dimensions.
+- Long label/summary truncates (class presence assertion); error badge renders in rightmost slot alongside other badges.
+
+### U2. Generalized edge-condition authoring
+
+**Goal:** Author success/failure on regular edges with distinct styling; parallel conditioned edges; cycle guard; honest interpreter-only banner.
+**Requirements:** R2, R3, R4, R5, R10.
+**Dependencies:** none (parallel with U1).
+**Files:**
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — `onConnect` direct-append with explicit unique edge ids (KTD-3) + ancestor-cycle guard (KTD-9); edge inspector success/failure native `<select>` gated per KTD-2 inside the existing disabled fieldset; compile-banner suffix match + info tone (KTD-4); `interactionWidth` on edges for a forgiving hit target (touch + pointer).
+- `packages/dashboard/app/components/workflow-flow-mapping.ts` (modify) — edge `className` for failure edges in `irEdgeToFlow`; always-rendered condition labels; dash styling hooks; ancestor-reachability helper for the cycle guard.
+- `packages/dashboard/app/components/WorkflowNodeEditor.css` (modify) — `.wf-edge-failure` (distinct dash pattern + `--ws-error`-derived stroke), success default styling, info-tone banner.
+- `packages/dashboard/app/components/__tests__/workflow-flow-mapping.test.ts` (extend) — mapping-level edge tests.
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (extend) — inspector gating tests.
+**Approach:** Edge-level behavior is tested at the mapping layer (React Flow doesn't render edges under jsdom). The inspector reuses `updateSelectedEdge` unchanged — only the rendering gate widens, and the condition control is a native `<select>` in the inspector's tab order. Failure edges from step-review sources remain impossible (verdict controls instead); rework stays intra-template-only (server-enforced). Banner content per KTD-4: states the workflow still runs and why, info token.
+**Test scenarios:**
+- Covers R3: failure condition set via `updateSelectedEdge` round-trips `flowToIr` → IR edge `condition: "failure"`; reload re-applies label + `wf-edge-failure` class.
+- Covers R4: two edges from one node (success + failure) with distinct ids both survive `flowToIr`/`irToFlow` round-trip; two sequential connects between the same pair don't collide or silently drop.
+- Covers KTD-9: connecting an edge whose target is an ancestor of its source is blocked with a toast; a rework edge inside a foreach template is still allowed.
+- Inspector shows success/failure select for a prompt-sourced edge; verdict controls (not the selector) for step-review-sourced; read-only note for split- and parse-steps-sourced.
+- Built-in workflow: edge inspector fieldset disabled (selector inert).
+- Compile rejection carrying the `require the workflow interpreter (deferred)` suffix (both the fan-out and off-main-path variants) → info-tone banner state; other compile errors → existing warning banner.
+- Default on connect remains `success` with a unique id.
+
+### U3. Deletion UX with cascade semantics
+
+**Goal:** Keyboard and button deletion for nodes and edges with explicit, safe cascades.
+**Requirements:** R6, R10.
+**Dependencies:** none (parallel; the delete-edge button touches the same inspector section as U2 but different fields — coordination, not a technical gate).
+**Files:**
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — `deleteKeyCode` (null when builtin), delete-node button in node inspector, delete-edge button in edge inspector, focus-to-canvas after keyboard deletion.
+- `packages/dashboard/app/components/workflow-flow-mapping.ts` (modify) — `cascadeDelete(nodes, edges, ids)` pure helper (this module owns the pure node/edge transformation layer; its test file already covers it).
+- `packages/dashboard/app/components/__tests__/workflow-flow-mapping.test.ts` (extend).
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (extend).
+**Approach:** Deleting a node removes all incident edges; no auto-bridge. Deleting a `foreach` group removes its `parentId` children and their intra-template edges (React Flow does not cascade parents → handle explicitly). `start`/`end` stay `deletable: false` and the keyboard path must honor per-node `deletable`. Deleting the last template child leaves the group with its existing `templateEmpty` hint (save-time validation, not delete-time block). After keyboard deletion, focus moves to the React Flow canvas container.
+**Test scenarios:**
+- Covers R6: cascade helper — deleting a mid-chain node removes its 2 incident edges and does not create a bridge edge.
+- Deleting a foreach group removes group + children + template edges.
+- Deleting the seeded step-execute child → group remains with `templateEmpty` rendering.
+- `start`/`end` not deletable via helper or keyboard config.
+- Builtin: `deleteKeyCode` null / delete buttons absent or disabled.
+
+### U4. Dialogs, inline rename/description, dirty guard
+
+**Goal:** Replace `window.prompt`/`window.confirm`; inline-editable name + description; confirm-on-discard across all dismissal paths.
+**Requirements:** R7, R10.
+**Dependencies:** none (parallel).
+**Files:**
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — local create-workflow dialog component (KTD-7), inline rename/description in the canvas header strip (KTD-10), dirty tracking, single dismissal guard.
+- `packages/dashboard/app/components/WorkflowNodeEditor.css` (modify).
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (extend).
+**Approach:** `useConfirm` for workflow delete and dirty-discard (provider mounted app-wide; tests must wrap in `ConfirmDialogProvider` or assert the no-op fallback = cancel). Dirty = normalized comparison — serialize both sides through `flowToIr` (loaded snapshot vs current) plus name/description, so mapping-layer defaults (e.g. `condition: "success"` materialized on load) don't produce spurious dirt; auto-layout position changes do count as dirty (they are persisted layout changes). **Dismissal guard design:** `useOverlayDismiss` handles only overlay clicks and its `onClose` is synchronous — it cannot await a confirm. Route every dismissal path (overlay click, X button, and a dedicated Escape keydown handler — Escape is NOT covered by `useOverlayDismiss`) through one synchronous guard that, when dirty, opens the `useConfirm` dialog and performs the real close only in the confirm callback. Guard the sidebar workflow switch the same way; built-ins are never dirty. Create dialog: inline error for empty/whitespace name; server-side duplicate-name rejection surfaces in-dialog without losing input; focus returns to the "New workflow" button on close (NewTaskModal pattern). Rename/description persist through the existing `updateWorkflow` PATCH on save.
+**Test scenarios:**
+- Covers R7: create flow — empty name shows inline error, valid name calls `createWorkflow` and activates it; server 4xx surfaces in-dialog.
+- Delete uses confirm: without provider (fallback false) delete does not fire; with provider + confirm, `deleteWorkflow` called.
+- Dirty guard: edit node → switch workflow → confirm dialog; cancel keeps edits, confirm discards and switches.
+- Escape on a dirty editor triggers the same confirm (dedicated keydown path); close with no edits → no prompt.
+- Inline rename: click name → input; Enter commits into save payload; Escape cancels; description round-trips.
+- Load→no-edit→close produces no spurious dirty prompt (normalized-compare regression test).
+
+### U5. Auto-layout
+
+**Goal:** One-click left-to-right tidy that never re-columns or unplaces nodes.
+**Requirements:** R8, R10.
+**Dependencies:** U1 (imports the exported card-dimension constants for spacing).
+**Files:**
+- `packages/dashboard/app/components/workflow-auto-layout.ts` (new) — pure `autoLayout(nodes, edges, columns)` returning new positions.
+- `packages/dashboard/app/components/__tests__/workflow-auto-layout.test.ts` (new).
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — toolbar button (hidden/disabled for builtin), apply positions, mark dirty.
+**Approach:** Topological layering from `start` (cycle-safe: rework edges and unreachable nodes handled — unreachables appended in a trailing layer). x = layer × spacing (spacing from the U1 card-width constant). v2: y = clamp to the node's current column band (`bandTop(i)`..`+220`), stacking same-layer/same-band nodes vertically until the band's capacity is reached, then staggering further nodes horizontally (extra x offset) so nothing escapes its band; v1: y = within-layer index × row height. Foreach groups move as a unit; children positions untouched (parent-relative). Pure function per the no-slow-tests rule.
+**Test scenarios:**
+- Covers R8: linear chain → strictly increasing x, stable y band per node (v2 fixture) — `strictColumnForY` unchanged for every node before/after.
+- Branching graph (success+failure) → branches occupy distinct rows, no overlaps at same x/y.
+- Dense column: more same-layer/same-band nodes than fit a 220px band → all stay in-band (column unchanged), overflow staggered in x, no two nodes share a position.
+- v1 graph (no columns) → layered positions, no NaN, deterministic output.
+- Foreach group: group repositioned, children's relative positions identical.
+- Unreachable node still receives a position (no node lost off-canvas).
+
+### U6. Empty/onboarding states
+
+**Goal:** Helpful empty states with clear CTAs.
+**Requirements:** R9, R10.
+**Dependencies:** none (parallel; each unit U1–U5 adds its own i18n keys to `packages/i18n/locales/en/app.json` and runs `pnpm i18n:extract && pnpm i18n:sync && pnpm i18n:types` as part of its own change — U6 adds only the empty-state strings).
+**Files:**
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — no-workflow empty state with create CTA; trivial-graph (start→end only) canvas hint pointing at the palette.
+- `packages/dashboard/app/components/WorkflowNodeEditor.css` (modify).
+- `packages/i18n/locales/en/app.json` (modify) — empty-state keys.
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (extend).
+**Approach:** Empty states are presentation-only (no new data fetches). The sidebar "New workflow" button remains the always-available create entry (including when a built-in is selected); the empty-state canvas message appears only when no workflow is loaded at all; the trivial-graph palette hint appears only for user-owned (non-builtin) workflows and disappears once any user node exists. Surface enumeration: no workflows / workflows-but-none-selected / trivial graph (user-owned) / builtin selected (read-only banner already exists; no hint, no canvas CTA) / mobile breakpoint reachability of toolbar actions.
+**Test scenarios:**
+- No workflows → empty state with create CTA; clicking opens the U4 dialog.
+- Trivial graph (user-owned) → palette hint rendered; hint absent once a user node exists; hint absent for builtins.
+- New i18n keys resolve (English defaults render; `pnpm i18n:lint` passes).
+- Test expectation for pure CSS additions: none — covered by the token/animation guard tests.
+
+---
+
+## Risks & Dependencies
+
+- **Compile-banner string coupling.** KTD-4 keys the info-tone banner on the compiler's `require the workflow interpreter (deferred)` message suffix. If that wording changes, the banner silently reverts to warning tone with no failing test — add a mapping-level test that imports/copies the literal suffix and a comment at the compiler message site noting the dashboard dependency.
+- **Two-layer server rejection.** `parseWorkflowIr` graph validation (illegal cycles, disconnected nodes) rejects at save, before compile. KTD-9's author-time cycle guard covers the common back-edge case; remaining parse-layer rejections keep the existing hard-error treatment by design (R5).
+- **Foreach group fit.** Larger cards may overflow the fixed 520×200 group; U1 adjusts the group constants and asserts fit in tests. Watch `extent: "parent"` clamping silently mangling layouts.
+- **jsdom can't render edges.** All edge styling/condition behavior must be asserted at the mapping layer; browser verification is the only proof edges render — see the stale-bundle note below.
+- **Stale-bundle trap.** `fn dashboard` serves the CLI's bundled client, not fresh dashboard builds; new node types render as `react-flow__node-default` and look like source bugs. Use `FUSION_CLIENT_DIR=$PWD/packages/dashboard/dist/client` (per `docs/solutions/developer-experience/browser-testing-dashboard-from-worktree-safely.md`); never port 4040, never `fn daemon` from a worktree.
+- **CSS token shape (IACVT).** Any animation must use `--duration-*` tokens; `--transition-*` as a bare duration silently kills the declaration (`docs/solutions/ui-bugs/css-animation-frozen-by-transition-token-shape-mismatch.md`); guarded by `animation-duration-tokens.css.test.ts`.
+- **Dashboard bundle constraint.** `@fusion/core` is types-only in the app build — any shared condition list/constant must be inlined in the dashboard (existing precedent: `STEP_REVIEW_VERDICTS`).
+- **Theme spread.** Edge colors derive from status tokens across 54 themes; the two-channel rule (R2: label + dash) keeps failure edges distinguishable even in low-contrast themes.
+- **Changeset.** This is user-facing behavior shipped via the bundled CLI; add a `@runfusion/fusion` changeset following the precedent of `.changeset/workflow-graph-editor-and-bundled-plugins.md` (AGENTS.md forbids changesets for the private packages themselves).
+
+---
+
+## System-Wide Impact
+
+- **Engine/core:** none — no executor, compiler, IR-schema, or store changes.
+- **Published CLI:** dashboard UI changes reach `@runfusion/fusion` via the bundled client (changeset, no new dependency).
+- **Affected parties:** workflow authors get a substantially better editor; existing saved workflows render unchanged semantically (layout positions and conditions round-trip as before).
+
+---
+
+## Sources & Research
+
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` — `onConnect` (~241), `updateSelectedEdge` (~359), edge inspector gating (~1306-1360), `handleSave` banner split (~431-494), `window.prompt`/`confirm` (~382, ~400).
+- `packages/dashboard/app/components/workflow-flow-mapping.ts` — `irEdgeToFlow` (~145), `flowEdgeToIr` (~382), band math (`bandTop`/`columnForY`/`strictColumnForY`, ~56-93), foreach constants (~198).
+- `packages/core/src/workflow-ir-types.ts:29-37` (free-form `condition`), `packages/core/src/workflow-ir.ts` (no condition-value validation; `validateNoIllegalCycles` exempts only rework edges — basis for KTD-9), `packages/engine/src/workflow-graph-executor.ts:385-392` (`failure` traversal), `packages/core/src/workflow-compiler.ts:55-149` (linearity rejection messages keyed by KTD-4), `packages/engine/src/workflow-graph-foreach.ts` (foreach genuinely emits `outcome: "failure"` — basis for its KTD-2 allowlisting).
+- `@xyflow/system` `addEdge`/`connectionExists` — dedupes on source/target/handles and ignores `id` (basis for KTD-3's direct-append).
+- `packages/dashboard/app/hooks/useConfirm.ts` + `ConfirmDialog.tsx` — confirm primitive (no-op fallback without provider); `packages/dashboard/app/hooks/useOverlayDismiss.ts` — overlay-only dismissal, no Escape handling, synchronous `onClose` (basis for U4's guard design).
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (api-mock + jsdom edge limitation, documented ~407-414), `workflow-flow-mapping.test.ts` (mapping-level pattern).
+- `docs/dashboard-guide.md:1065-1175` — styling guide (tokens, button-freeze, animation tokens); `AGENTS.md` — no slow tests, changeset policy, dashboard static-import constraint, surface enumeration.
+- `docs/solutions/developer-experience/browser-testing-dashboard-from-worktree-safely.md`, `docs/solutions/ui-bugs/css-animation-frozen-by-transition-token-shape-mismatch.md`.
+- `docs/plans/2026-06-03-001-feat-executable-custom-workflows-node-editor-plan.md` (original editor MVP), `docs/plans/2026-06-03-002-feat-workflow-interpreter-cutover-plan.md` (where branching execution lives).

 ### Global Settings
 User-level settings persisted server-side that apply across all Surfaces and all projects, as opposed to per-project settings. Values are validated at the write boundary — an invalid value is dropped rather than persisted — so every reader can trust what it loads.
 
+### Workflow Setting
+A typed setting declared by a workflow in its IR (id, type, default, options), mirroring the custom-task-field shape. Declarations describe the schema; *values* persist per workflow + project through a single validating store authority, so built-in workflows can carry values without their IR being editable. The engine consumes **effective settings** — stored value falling back to declaration default, with values that no longer validate against the current declaration dropped (never fed to execution).
+
 ### Three-Tier Setting
 The named persistence pattern for a user preference on the dashboard: a device-local cache for instant reads, a write-through to Global Settings so other Surfaces see it, and a hydrate-on-mount from the server when no local value exists. A local or in-flight user choice always wins over server hydration, and changes propagate to other open tabs.

+type: feat
+status: active
+date: 2026-06-04
+depth: deep
+origin: none (solo planning bootstrap; builds on docs/plans/2026-06-03-003-feat-workflow-custom-columns-traits-plan.md and docs/plans/2026-06-04-001-feat-step-inversion-workflow-modelable-steps-plan.md)

+# feat: Workflow settings mechanism, settings hard-move, and Settings UI redesign
+
+## Summary
+
+Give workflows a first-class **typed settings mechanism**: workflows declare settings in their IR (mirroring the shipped custom-task-fields pattern), setting *values* persist per `(workflowId, projectId)` through a single validating store authority, and the engine resolves **effective settings per task** at executor entry. Then **hard-move** the global/project settings that are actually workflow policy — step execution, review/approval, per-phase model lanes — onto this mechanism via a one-time, idempotent, marker-gated migration that removes the keys from the settings schema entirely. Finally, **redesign the Settings modal**: replace ~7,900 lines of ad-hoc inline controls with shared schema-driven field primitives, per-section components with co-located CSS, consistent grouping/naming, and redirect stubs pointing users to the workflow editor for moved settings.
+
+Keys already destined for column **trait** config under the columns/traits track (merge strategy cluster, `maxConcurrent` → WIP trait) go there, not here — this plan draws that boundary explicitly (KTD-4).
+
+---
+
+## Problem Frame
+
+The columns/traits and step-inversion tracks made workflows the home for board and step *policy* — columns, traits, custom task fields, step modeling. But the policy *knobs* that parameterize that behavior still live as ambient project/global settings in `packages/core/src/settings-schema.ts`: `workflowStepTimeoutMs`, `runStepsInNewSessions`, `requirePrApproval`, `reviewHandoffPolicy`, per-phase model lanes, and dozens more. This is now incoherent:
+
+- A workflow models *how* tasks execute, but the timeouts, review gates, and model lanes that govern that execution are configured somewhere else entirely, with no relationship to the workflow.
+- The columns plan's identity posture (KTD-6) says user-lowerable enforcement floors belong *inside an explicitly authored workflow, never as ambient settings* — the current settings catalog violates this.
+- The Settings modal has grown to ~7,900 lines of bespoke inline controls across ~25 sections with no shared field components, making every settings change expensive and the UI inconsistent.
+
+There is no mechanism for a workflow to declare a setting at all — that's the gap this plan fills first, then exploits.
+
+---
+
+## Scope Boundaries
+
+### In scope
+
+- `settings` declarations on WorkflowIr v2 (additive): `WorkflowSettingDefinition[]` with typed values, defaults, enum options, descriptions, render hints; `validateSettings` in `parseWorkflowIr`.
+- A per-`(workflowId, projectId)` setting-**value** store (new table, schema bump) with a single validating write authority; values writable for built-in workflows even though built-in IR is non-editable.
+- Per-task effective-settings resolution in core, consumed by the engine at executor entry, preserving the flat `Partial<Settings>` read shape.
+- Built-in workflow declarations for every moved key, with defaults byte-equal to today's `DEFAULT_PROJECT_SETTINGS` values.
+- `WorkflowSettingsPanel` in the workflow node editor (declarations + defaults; per-project values in project context); agent-tool parity (`fn_workflow_create/update` declarations; a value read/write path).
+- One-time hard-move migration (per-project marker, idempotent) of the moved-key catalog (see U4) out of `DEFAULT_PROJECT_SETTINGS`, with tombstone allowlist, explicit value nulling, and surface sweep: settings export v2, cross-node sync guard, SettingsModal save-split, CLI, consistency test.
+- Full SettingsModal redesign: shared schema-driven field primitives, per-section components + co-located CSS files, regrouped navigation, redirect stubs for moved settings, i18n throughout.
+
+### Deferred to Follow-Up Work
+
+- Removing the redirect stubs (one release after this ships).
+- A `workflowSettings` channel in cross-node settings *sync* (this plan excludes moved keys from sync and reports the exclusion; full sync of the value table is follow-up — see KTD-8).
+- Per-task setting value overrides (values are per workflow+project only this round).
+- Plugin-contributed setting types or plugin-declared settings.
+- Moving capacity/scheduler ops knobs (`backlogPressure*`, `stale*`, `pollIntervalMs`, etc.) — these are engine/scheduler operations policy, not per-workflow process policy; reconsider only after the mechanism proves out.
+- Migrating merge-cluster keys — owned by the columns plan's merge-trait track (U7 there), not this plan.
+
+### Outside this plan's identity
+
+- No global-default-plus-workflow-override layering: the user decision is a hard move. A moved key has exactly one home.
+- Integrity guarantees (lost-work trio, crash recovery, audit) stay non-configurable — they never become workflow settings.
+- Device-local three-tier prefs (theme, language, font scale) stay exactly as they are.
+
+---
+
+## Requirements
+
+**Mechanism**
+
+- R1. Workflows can declare typed settings in IR (`id`, `name`, `type`, `default`, `options`, `description`, render hints); declarations are validated at save by `parseWorkflowIr` with the same rigor as `validateFields` (unique ids, type whitelist, options iff enum-kind).
+- R2. Setting values persist per `(workflowId, projectId)` through a single store write authority that validates each value against the named workflow's declaration schema and rejects invalid values with typed errors — invalid values are never persisted.
+- R3. The engine resolves effective settings **per task** (stored value → declaration default), as a flat `Partial<Settings>`-shaped object, via a never-throw resolver; all moved-key engine read sites receive values from this resolution.
+- R4. Built-in workflows (`builtin:coding`, stepwise) declare every moved setting with defaults equal to today's `DEFAULT_PROJECT_SETTINGS` values; setting *values* for built-ins are writable even though built-in IR is not editable.
+- R5. The workflow node editor has a settings panel for declarations/defaults and per-project values; `fn_workflow_create/update` accept `settings` declarations and agents can read/write values with the same typed-rejection contract.
+
+**Migration**
+
+- R6. A one-time, idempotent, per-project migration (gated by a persisted migration marker) snapshots each project's effective moved-key values, writes them to **every workflow the project's tasks can resolve** — the distinct `task_workflow_selection` workflowIds in use, unioned with the resolved project default, where an unset/empty `defaultWorkflowId` normalizes to `builtin:coding` (matching the resolver's falsy-id degradation) — removes the keys from `DEFAULT_PROJECT_SETTINGS`/`GLOBAL` schema objects, and explicitly nulls persisted raw values.
+- R7. Every settings surface stays consistent with the move: keys lists/predicates, validation, export/import (v2), cross-node sync, SettingsModal save-split, `useAppSettings`, CLI settings commands — guarded by a consistency test so the lists cannot silently drift.
+- R8. Pre-migration payloads cannot resurrect moved keys: importing a v1 export upgrades moved keys into workflow setting values; sync of moved keys is suppressed via the tombstone allowlist.
+
+**Settings UI**
+
+- R9. SettingsModal is rebuilt from shared schema-driven field primitives (toggle/number/select/text/textarea rows) and per-section components with co-located CSS files following the dashboard CSS conventions.
+- R10. Each moved setting's former location shows a redirect stub ("moved to the workflow editor" with a link) for one release.
+- R11. Behavior of remaining settings is preserved: save-splitting by scope predicates, null-as-delete clears, changed-only project writes, three-tier device prefs untouched, all strings `t()`-wrapped.
+

+
+## High-Level Technical Design
+
+Effective-settings resolution (the load-bearing data flow — flat shape preserved so ~20 engine read sites don't change):
+
+```mermaid
+flowchart TB
+  subgraph Declarations
+    IR["WorkflowIr v2<br/>settings: WorkflowSettingDefinition[]"]
+    BI["Built-in workflow IRs<br/>(declare all moved keys,<br/>defaults = legacy defaults)"]
+  end
+  subgraph Values
+    VT["workflow_settings table<br/>(workflowId, projectId, values JSON)"]
+    WA["Store write authority<br/>validate → typed rejection<br/>(invalid never persisted)"]
+    WA --> VT
+  end
+  T["Task"] --> RES
+  IR --> RES
+  BI --> RES
+  VT --> RES
+  RES["resolveEffectiveSettings(task)<br/>value ?? declaration.default<br/>drop-on-orphan, never-throw"]
+  RES --> ENG["Engine executor entry:<br/>flat Partial&lt;Settings&gt; shape<br/>settings.workflowStepTimeoutMs etc."]
+  PS["Project settings<br/>(remaining keys only)"] --> ENG
+```
+
+One-time migration sequence (per project, idempotent, marker-gated):
+
+```mermaid
+flowchart TB
+  S["Store open / migration runner"] --> M{"project has<br/>settingsMigrationVersion ≥ 1?"}
+  M -->|yes| DONE["no-op"]
+  M -->|no| SNAP["Snapshot effective values of<br/>moved keys (typed read,<br/>pre-removal schema)"]
+  SNAP --> WV["Write values to every in-use<br/>(workflowId, projectId): distinct task<br/>selections ∪ resolved project default<br/>(unset default → builtin:coding)"]
+  WV --> NULLS["Explicitly null moved keys<br/>in raw project + global stores"]
+  NULLS --> MARK["Set marker"]
+  MARK --> DONE2["Engine + UI read only<br/>new home from now on"]
+  TOMB["Tombstone allowlist<br/>(moved-key names)"] -.->|"shields: sync diff,<br/>v1 import, stale writers"| NULLS
+```
+
+The schema-object key removal (from `DEFAULT_PROJECT_SETTINGS`) ships in the same commit as the migration — the two are inseparable, because `GlobalSettingsStore`/project `updateSettings` re-inject `DEFAULT_*` values after deletion (`packages/core/src/global-settings.ts:181-211`): a key left in the DEFAULT object re-materializes on the next unrelated save and silently overrides the migrated value.
+
+---
+
+## Key Technical Decisions
+
+- KTD-1 — **Mirror the fields pattern exactly.** `WorkflowSettingDefinition` clones the shape of `WorkflowFieldDefinition` (`packages/core/src/workflow-ir-types.ts:90-98`); `validateSettings` clones `validateFields` (`packages/core/src/workflow-ir.ts:659-727`); the editor panel clones `WorkflowFieldsPanel.tsx`. This is the established, shipped pattern for "workflow-declared typed schema" — inventing a second idiom would be gratuitous divergence. Settings get their **own** render-hint type (widget only — no `card`/`detail` placement, which is task-card-specific).
+
+- KTD-2 — **Values live per `(workflowId, projectId)` in a new table, not in IR.** Built-in workflows are non-editable (`isBuiltinWorkflowId` guard in store CRUD), so values cannot be written into built-in IR; and per-project tuning of the same workflow must survive the migration (two projects using `builtin:coding` with different step timeouts). Declarations describe the schema; the value table carries the data — exactly the workflow-fields ↔ `tasks.customFields` split, one level up. Value writes are validated against the *named* workflow's schema (not the project's current default workflow), and built-in workflow values are writable while built-in declarations are not — two distinct error paths in the write authority.
+
+- KTD-3 — **Per-task effective-settings resolution, flat shape.** The engine reads moved keys as flat fields on `Partial<Settings>` at ~20 sites (`packages/engine/src/executor.ts:9974, :2149, :5154`, `packages/engine/src/step-session-executor.ts:671`, reviewer/merger). A `resolveEffectiveSettings(task)` sibling of `resolveWorkflowIrForTask` (`packages/core/src/workflow-ir-resolver.ts`) builds the same flat shape from value-table + declaration defaults at executor entry, so read sites keep their exact expressions. Same never-throw degradation contract as the IR resolver. Each read site's hardcoded `?? <literal>` fallback must be audited to match the built-in declaration default — otherwise resolution returning `undefined` silently overrides migrated values.
+
+- KTD-4 — **Trait-config boundary.** Column-scoped policy belongs to column *traits* (merge strategy/squash/fileScope → merge trait; `maxConcurrent` → WIP trait, per columns plan KTD-6/U6/U7). Workflow *settings* carry workflow-scoped policy not tied to a single column: step execution knobs, review/approval policy, per-phase model lanes. A key gets exactly one home; the moved-key catalog (U4) records the home for every candidate so the same policy never has two sources of truth.
+
+- KTD-5 — **Hard-move = schema removal + tombstones + explicit nulls + per-project marker; no experimental flag.** A behavior flag would require moved keys to exist in both homes simultaneously (flag-OFF reads old, flag-ON reads new), which contradicts a hard move and re-creates the dual-writer hazard. Instead, the migrated/not-migrated state is per project, gated by a persisted `settingsMigrationVersion` marker, and transitions exactly once. A `MOVED_SETTINGS_KEYS` tombstone allowlist (the only remaining record of the old names) shields the surfaces that can encounter old payloads: sync diff, v1 import, stale CLI writers. Safety comes from characterization tests proving effective-value equivalence across the migration boundary, not from a flag.
+
+- KTD-6 — **Drop-on-orphan for setting values (deliberate divergence from fields).** `reconcileFieldsOnWorkflowChange` retains orphaned task-field values and surfaces them in a disclosure — fine for display data, dangerous for policy the engine consumes (a retyped enum→number setting with a stale string value would feed garbage into execution). Effective resolution drops values that no longer validate against the current declaration and falls to the declaration default. The editor surfaces dropped values; the engine never sees them.
+
+- KTD-7 — **Model-lane resolution chain.** Per-phase project lanes (`executionProvider/ModelId`, `planningProvider/ModelId`, `validatorProvider/ModelId`, fallbacks, title summarizer) move to workflow settings. The documented chain (`packages/engine/src/executor.ts:5755-5770`, the `resolveExecutorSessionModel` lane-hierarchy site) becomes: workflow-setting lane → global lane (`executionGlobalProvider` etc., which stay global) → project default override → global default. An empty workflow lane falls through; characterization tests pin the chain before and after.
+
+- KTD-8 — **Export v2; sync excludes moved keys this round.** `settings-export.ts` bumps to `version: 2` with a `workflowSettings` section (declarations are in workflows; export carries values). Importing v1 upgrades moved keys into workflow setting values using the same write-target rule as the migration (in-use workflows ∪ resolved default, unset default normalized to `builtin:coding`) instead of dead-writing them into project settings. Cross-node settings sync (`packages/dashboard/src/routes/register-settings-sync-routes.ts:15-33`) filters moved keys out of diffs/push/pull via the tombstone list and surfaces "workflow settings are not synced yet" in the sync UI; a full sync channel is deferred (Scope Boundaries).
+
+- KTD-9 — **Cascade-delete values on workflow deletion.** Deleting a custom workflow deletes its value rows; tasks pinned to a deleted workflow already degrade to `builtin:coding` via the resolver and therefore read built-in declarations + built-in values. No unreachable orphan rows.
+
+- KTD-10 — **Schema-driven Settings UI primitives.** The redesign introduces shared field-row primitives (toggle/number/select/text/textarea + section scaffolding) rendered from a per-section descriptor, the same render-by-type idiom as `WorkflowFieldsPanel` widgets. SettingsModal becomes a shell (nav + save-split + scope handling) composing per-section components, each with a co-located CSS file. This is what makes the modal cheap to change and is also the convergence point: `WorkflowSettingsPanel` value editing reuses the same primitives.

+
+## Implementation Units
+
+### U1. Workflow IR settings declarations + validation + built-in declarations
+
+- **Goal:** Workflows can declare typed settings; built-ins declare the full moved-key catalog.
+- **Requirements:** R1, R4
+- **Dependencies:** none
+- **Files:** `packages/core/src/workflow-ir-types.ts`, `packages/core/src/workflow-ir.ts`, `packages/core/src/builtin-coding-workflow-ir.ts`, `packages/core/src/builtin-stepwise-coding-workflow-ir.ts`, `packages/core/src/__tests__/workflow-ir.test.ts`
+- **Approach:** Add `settings?: WorkflowSettingDefinition[]` to `WorkflowIrV2` (additive; v1 stays frozen). Definition shape: `{ id, name, type, default?, options?, description?, render? }` with type whitelist `string | text | number | boolean | enum | multi-enum`; settings-specific render hint (`widget` only). `validateSettings` in `validateV2` mirrors `validateFields`: non-empty unique ids, type whitelist, options iff enum-kind, unique option values, default validates against its own type/options. Built-in IRs declare every moved key with defaults byte-equal to current `DEFAULT_PROJECT_SETTINGS` literals. Note: presence of `settings` keeps IR v2 under `downgradeIrToV1IfPure`.
+- **Patterns to follow:** `validateFields` (`workflow-ir.ts:659-727`), `WorkflowFieldDefinition` types, `WorkflowIrError` surfacing.
+- **Test scenarios:**
+  - Valid declaration of each type parses and round-trips through `parseWorkflowIr`.
+  - Duplicate setting ids → `WorkflowIrError`; empty id → error; unknown type → error.
+  - `enum` without options → error; options on non-enum type → error; duplicate option values → error.
+  - Default value violating its own type (`type: number`, `default: "x"`) or enum options → error.
+  - Built-in coding workflow declares every key in `MOVED_SETTINGS_KEYS` and each declaration default strictly equals the legacy `DEFAULT_PROJECT_SETTINGS` literal (consistency assertion — this is the parity anchor for the migration).
+  - IR with `settings` present is not downgraded to v1.
+- **Verification:** `pnpm test` for core IR suites green; consistency assertion ties built-in defaults to legacy literals.
+
+### U2. Setting-value store: table, write authority, validation core
+
+- **Goal:** Persist values per `(workflowId, projectId)` behind a single validating authority.
+- **Requirements:** R2, R4
+- **Dependencies:** U1
+- **Files:** `packages/core/src/db.ts`, `packages/core/src/store.ts`, `packages/core/src/workflow-settings.ts` (new), `packages/core/src/__tests__/workflow-settings.test.ts`, `packages/core/src/__tests__/db-migrate.test.ts`
+- **Approach:** New table `workflow_settings (workflowId, projectId, values JSON, updatedAt)` with composite PK; `SCHEMA_VERSION` bump (additive, forward-only, idempotent migration step). `workflow-settings.ts` is the side-effect-free validation core mirroring `task-fields.ts`: `validateSettingValuePatch(declarations, patch)` → typed rejections (`unknown-setting`, `type-mismatch`, `enum-violation`, `no-settings-defined`), plus `resolveEffectiveSettingValues(declarations, stored)` implementing drop-on-orphan (KTD-6) with an explicit comment marking the deliberate divergence from the field reconciler. Store authority `updateWorkflowSettingValues(workflowId, projectId, patch)`: validates against the **named** workflow's declarations; built-in workflow ids accepted for value writes (declaration edits stay rejected); null-as-delete per key. Cascade-delete rows in workflow deletion (KTD-9).
+- **Execution note:** Bumping `SCHEMA_VERSION` requires the broad literal sweep — `grep -rn 'toBe(<old>)' packages/` hits ~40+ sites across ≥8 test files (`db.test.ts` ~26, `db-migrate.test.ts`, `goals-schema.test.ts`, `task-documents.test.ts`, plus insight-store/run-audit/store-merge-queue/merge-request-record/mission-store suites); update all of them atomically in this unit's commit. The U4 settings migration is a separate commit with no DB schema change.
+- **Patterns to follow:** `updateTaskCustomFields` / `validateCustomFieldPatch` (`store.ts:6947`, `task-fields.ts`), `addColumnIfMissing` migration discipline, db-migrate forward-path tests.
+- **Test scenarios:**
+  - Write a valid value for a custom workflow → persisted; read back typed.
+  - Write value for `(builtin:coding, project)` → accepted (R4); attempt to edit built-in declarations via workflow update → still rejected.
+  - Type-mismatch / unknown-setting / enum-violation patches → typed rejection, nothing persisted (write boundary contract).
+  - Null value in patch deletes the key; subsequent effective resolution falls to declaration default.
+  - Retype a declared setting (enum→number) with a stale string value stored → effective resolution drops it and returns declaration default; stored row untouched until next write (drop-on-orphan).
+  - Delete custom workflow → its value rows are gone; task pinned to deleted workflow resolves builtin values.
+  - db-migrate forward-path test for the new version; schema-version literal sweep complete.
+- **Verification:** Core suites green; no row rewrites in migration; corruption-resilience posture unchanged.
+
+### U3. Effective-settings resolution + engine integration + fallback audit
+
+- **Goal:** Engine reads moved keys from per-task resolution; behavior is characterization-identical for untouched defaults.
+- **Requirements:** R3
+- **Dependencies:** U1, U2
+- **Files:** `packages/core/src/workflow-ir-resolver.ts` (or sibling `workflow-settings-resolver.ts`), `packages/engine/src/executor.ts`, `packages/engine/src/step-session-executor.ts`, `packages/engine/src/reviewer.ts`, `packages/engine/src/merger.ts`, `packages/core/src/__tests__/workflow-settings-resolver.test.ts`, `packages/engine/src/__tests__/executor-settings.test.ts`
+- **Approach:** `resolveEffectiveSettings(task | workflowId+projectId)` composes `resolveWorkflowIrForTask` + value table + drop-on-orphan into a flat `Partial<Settings>`-shaped object (never-throw, degrade like the IR resolver). Engine builds it once at executor entry and merges over the remaining project/global settings object so the ~20 read sites keep their exact `settings.<key>` expressions. Audit every moved-key read site's hardcoded `?? <literal>` fallback (e.g. `executor.ts:9974` `?? 360_000`, `step-session-executor.ts:671`) and align each with the built-in declaration default — assert alignment in a test rather than by eye. Model-lane chain rewired per KTD-7.
+- **Execution note:** Characterization-first — capture current effective values consumed by a scripted run (default settings, and a customized-project fixture) before wiring resolution; then prove the post-wiring run consumes identical values.
+- **Patterns to follow:** `resolveWorkflowIrForTask` never-throw contract; `workflow-parity.ts` observation machinery for characterization.
+- **Test scenarios:**
+  - Task on `builtin:coding`, no stored values → effective values equal legacy defaults for every moved key (parity anchor).
+  - Stored value for `(workflow, project)` → engine read site receives it (spot-check `workflowStepTimeoutMs`, `runStepsInNewSessions`, `requirePrApproval`).
+  - Two tasks in one project resolving different workflows → each gets its own workflow's effective values (per-task resolution, not per-project).
+  - Workflow lacking a declaration for a moved key (custom workflow with empty settings) → falls to the declaration-absent path → read-site fallback; test asserts the fallback equals the legacy default (I2 guard).
+  - New custom workflow created post-migration with empty settings → effective values are declaration/read-site defaults, **not** the project's prior customized values — asserted explicitly as expected behavior (and documented in U10's user docs: switching a project to a new workflow starts from that workflow's defaults).
+  - Model lanes: workflow lane set → wins; empty → global lane; both empty → global default (chain pinned, KTD-7).
+  - Corrupt/missing workflow → resolver degrades, never throws, run proceeds on builtin declarations.
+  - Fallback-alignment assertion: for every moved key, read-site literal fallback === built-in declaration default.
+- **Verification:** Engine suites green; characterization fixtures prove value-equivalence pre/post.
+
+### U4. One-time hard-move migration + tombstones + schema removal
+
+- **Goal:** Each project's effective moved-key values land in the value table; moved keys leave the settings schema for good.
+- **Requirements:** R6, R8
+- **Dependencies:** U1, U2, U3
+- **Files:** `packages/core/src/settings-schema.ts`, `packages/core/src/settings-validation.ts`, `packages/core/src/global-settings.ts`, `packages/core/src/store.ts`, `packages/core/src/moved-settings.ts` (new: `MOVED_SETTINGS_KEYS` tombstone list + marker helpers), `packages/core/src/__tests__/settings-migration.test.ts`
+- **Approach:** Single commit containing: (a) `MOVED_SETTINGS_KEYS` tombstone allowlist with the definitive moved-key catalog — step execution (`workflowStepTimeoutMs`, `workflowStepScopeEnforcement`, `planOnlyScopeLeakEnforcement`, `workflowRevisionForkOnScopeMismatch`, `strictScopeEnforcement`, `runStepsInNewSessions`, `maxParallelSteps`, `buildRetryCount`, `buildTimeoutMs`, `verificationFixRetries`, `maxPostReviewFixes`), review/approval (`requirePrApproval`, `requirePlanApproval`, `reviewHandoffPolicy`, `maxReviewerContextRetries`, `maxReviewerFallbackRetries`, the `reflection*` trio — verify during the U3 audit that `reflectionAfterTask`/`reflectionIntervalMs` actually have engine read sites; any key without a per-task reader stays in project settings per the catalog-shrink rule), and per-phase model lanes (`executionProvider/ModelId`, `planningProvider/ModelId` + fallback, `validatorProvider/ModelId` + fallback, `titleSummarizerProvider/ModelId` + fallback); each entry records its new home and built-in default. `completionDocumentationMode` stays in project settings — `triage.ts:1082` reads it via `store.getSettings()` outside per-task execution scope, so it fails the per-task-reader rule. Merge-cluster and `maxConcurrent` keys are explicitly annotated as trait-owned (KTD-4) and not in this list. (b) Migration runner at store open, per project: skip if `settingsMigrationVersion ≥ 1`; snapshot effective values via the **pre-removal typed read**; write the snapshot to **every in-use `(workflowId, projectId)`** — the distinct workflowIds across the project's `task_workflow_selection` rows, unioned with the resolved project default, normalizing an unset/empty `defaultWorkflowId` to `builtin:coding` (the id every selection-less task resolves to) — then explicitly null raw persisted keys in both stores; set marker. The value-writes and the project-store nulling share one SQLite transaction (same DB); the global-store null is defensive only (all moved keys are project-scoped) and may follow outside the transaction. (c) Removal of moved keys from `DEFAULT_PROJECT_SETTINGS`/`DEFAULT_GLOBAL_SETTINGS` and their validators — inseparable from (b) because the stores re-inject DEFAULT values after deletion (`global-settings.ts:181-211`). The `SCHEMA_VERSION` bump itself lands in U2 (the new table); this commit contains no DB schema change — only the settings-schema key removal, tombstones, and the runner.
+- **Execution note:** Characterization-first: a fixture project with customized moved keys must produce identical engine-effective values before and after the migration runs.
+- **Test scenarios:**
+  - Fresh project post-migration: effective values equal declaration defaults; no moved key present in `PROJECT_SETTINGS_KEYS`.
+  - Project with customized `workflowStepTimeoutMs`/`requirePrApproval`/`executionProvider` → values appear under every in-use `(workflowId, projectId)`; raw settings file no longer contains the keys; engine-effective values identical pre/post (characterization).
+  - Mixed-pinning fixture: one task on `builtin:coding` (no selection row) and one pinned to a custom workflow, project `defaultWorkflowId` unset → both tasks read identical customized effective values post-migration (the in-use-union write target plus the `builtin:coding` normalization).
+  - Project with `defaultWorkflowId` unset and no task selections → snapshot lands on `(builtin:coding, projectId)`; a default-workflow task reads it identically pre/post.
+  - Migration runs twice → second run is a no-op (idempotency via marker).
+  - Crash between value-write and nulling → re-run converges to the same end state (write-then-null is re-runnable; values overwrite identically).
+  - Post-migration save of an unrelated setting does **not** re-materialize any moved key (the C1 default re-injection trap — the load-bearing regression test).
+  - Project whose `defaultWorkflowId` points at a deleted/missing workflow → values land on `builtin:coding` (resolver degradation path).
+  - Stale writer sends a moved key through `updateSettings` post-migration → key is filtered/ignored via tombstone, not persisted.
+- **Verification:** Migration suite green; the default re-injection regression test is the gate; characterization equivalence proven.
+
+### U5. Surface sweep: export v2, sync guard, CLI, consistency test
+
+- **Goal:** Every settings surface agrees about which keys exist where; old payloads can't resurrect moved keys.
+- **Requirements:** R7, R8
+- **Dependencies:** U4
+- **Files:** `packages/core/src/settings-export.ts`, `packages/dashboard/src/routes/register-settings-sync-routes.ts`, `packages/dashboard/src/routes/register-settings-sync-helpers.ts`, `packages/dashboard/app/hooks/useNodeSettingsSync.ts`, `packages/cli/src/commands/settings.ts`, `packages/cli/src/commands/settings-export.ts`, `packages/cli/src/commands/settings-import.ts`, `packages/core/src/__tests__/settings-export.test.ts`, `packages/core/src/__tests__/settings-consistency.test.ts` (new)
+- **Approach:** Export bumps to `version: 2` with a `workflowSettings` value section; importing v1 upgrades moved keys into the project-default workflow's values (KTD-8); merge-mode semantics documented for the new section. Sync: `computeSettingsDiff` filters `MOVED_SETTINGS_KEYS` from field lists; inbound `applyRemoteSettings` drops them; the sync UI renders an inline, non-dismissible informational note at the bottom of the sync diff section ("Workflow settings are not synced across nodes yet.", `--text-muted`, no action affordance this release). CLI settings commands stop listing moved keys and print a pointer to the workflow editor. New consistency test (registration-drift lesson): asserts that schema key lists, tombstone list, built-in declarations, and the SettingsModal section descriptors are mutually consistent — a key may appear in exactly one regime.
+- **Test scenarios:**
+  - Export post-migration → v2 payload carries workflow setting values; no moved key under `project`.
+  - Import v1 payload containing `workflowStepTimeoutMs` → value lands in the default workflow's values, not project settings; remaining v1 keys import normally.
+  - Import v2 payload round-trips values.
+  - Sync diff between migrated and unmigrated nodes → moved keys never appear in diff/push/pull; inbound push containing a moved key is dropped (multi-node race guard).
+  - Consistency test fails if a key is simultaneously in `DEFAULT_PROJECT_SETTINGS` and `MOVED_SETTINGS_KEYS`, or in tombstones but missing from built-in declarations.
+  - CLI `settings` listing excludes moved keys and shows the redirect hint.
+- **Verification:** Export/sync/CLI suites green; consistency test in place as the permanent drift guard.
+
+### U6. WorkflowSettingsPanel in the node editor + routes
+
+- **Goal:** Users author setting declarations and edit values where the rest of workflow config lives.
+- **Requirements:** R5
+- **Dependencies:** U1, U2
+- **Files:** `packages/dashboard/app/components/WorkflowSettingsPanel.tsx` (new), `packages/dashboard/app/components/WorkflowSettingsPanel.css` (new), `packages/dashboard/app/components/WorkflowNodeEditor.tsx`, `packages/dashboard/app/utils/workflow-flow-mapping.ts`, dashboard server routes for value read/write, `packages/dashboard/app/__tests__/WorkflowSettingsPanel.test.tsx`
+- **Approach:** Clone the `WorkflowFieldsPanel` conventions: sibling panel in the editor, kebab-case id slugify, immutable id (edit = remove+add with warning), client mirrors the server type whitelist, validation server-side at save surfaced through the shared error band, i18n via `useTranslation`. The panel has an internal **tab pair** — "Definitions" (declarations + defaults; custom workflows only, read-only declaration view for built-ins) and "Values" (per-project values, editable for any workflow including built-ins) — so the editor gains one sibling panel, not two. Declaration edits ride the editor's existing IR save flow; **value edits batch in panel state and commit through a dedicated Save action in the Values tab** (one patch to the store authority route — never per-field writes, never fused with the IR Save; the two write authorities stay separate). Rejections render the typed error per field. The Values tab **binds to the projectId active when the panel opened**; if the active project changes while the editor is open, show a stale-context notice ("Values shown are for project X — reopen to edit the current project") instead of silently rebinding writes; when no project is active, the Values tab states that a project context is required. Orphaned stored values (KTD-6) render in a collapsible "Orphaned values" section below the live list: each row shows the key id, the stored raw value, and a delete affordance (null-patch through the store authority) — no edit affordance, with a note explaining the definition changed or was removed.
+- **Patterns to follow:** `WorkflowFieldsPanel.tsx` + `.css`, editor save flow in `WorkflowNodeEditor.tsx`, CSS token conventions (`--duration-*`, `--text-muted`).
+- **Test scenarios:**
+  - Declare a setting of each type via the panel → IR save round-trips; invalid declaration (dup id) surfaces the server error band.
+  - Built-in workflow: declarations render read-only; values editable for the active project.
+  - Value edits batch: editing three fields then Save emits exactly one patch; a rejected field keeps the other two applied per the authority's typed-rejection semantics and renders the per-field error.
+  - Value edit with type mismatch → typed rejection rendered, value unchanged.
+  - No active project → Values tab shows the requires-project state, no write path.
+  - Active project changes while editor open → stale-context notice shown; pending edits do not write to the new project.
+  - Orphaned values render in the collapsible disclosure with delete affordance; delete removes the stored row via null-patch.
+- **Verification:** Dashboard suites green; manual editor walkthrough (declare → set value → engine pick-up) in a worktree dashboard instance.
+
+### U7. Agent-tool and SDK parity
+
+- **Goal:** Agents can do everything the editor can: declare settings, read/write values.
+- **Requirements:** R5
+- **Dependencies:** U1, U2
+- **Files:** `packages/cli/src/extension.ts`, `packages/core/src/agent-prompts.ts`, `packages/cli/skill/fusion/references/engine-tools.md`, `packages/plugin-sdk` type surface, `packages/cli/src/__tests__/extension-workflow-settings.test.ts`
+- **Approach:** `fn_workflow_create/update` accept `settings` declaration arrays (validated by the same `parseWorkflowIr` path; built-in declaration edits rejected with the existing built-in error). New value read/write tool (or extension of an existing workflow tool) with the typed-rejection contract from U2; reads return effective values (post drop-on-orphan) plus raw stored values so agents see both. Document in engine-tools reference; mirror types in plugin-sdk.
+- **Test scenarios:**
+  - Agent creates a workflow with settings declarations → persisted and validated identically to editor saves.
+  - Agent writes a valid value for `(builtin:coding, project)` → accepted; declaration edit on builtin → rejected with the distinct error (I8 two-path contract).
+  - Agent write with enum violation → typed rejection surfaced through the tool result.
+  - Tool read returns effective values matching `resolveEffectiveSettings`.
+- **Verification:** CLI extension suites green; engine-tools doc updated.
+
+### U8. Settings UI primitives + section scaffolding
+
+- **Goal:** The shared, schema-driven building blocks the redesigned modal and the workflow settings panel both compose.
+- **Requirements:** R9
+- **Dependencies:** none (parallel with U1-U5)
+- **Files:** `packages/dashboard/app/components/settings/` (new directory: `SettingsFieldRow.tsx`, `SettingsToggleRow.tsx`, `SettingsNumberRow.tsx`, `SettingsSelectRow.tsx`, `SettingsTextRow.tsx`, `SettingsSection.tsx`, plus co-located `.css` per component), `packages/dashboard/app/__tests__/settings-primitives.test.tsx`
+- **Approach:** Primitives render from a field descriptor (`{ key, labelKey, type, options?, scope, help? }`) — the same render-by-type idiom as `WorkflowFieldsPanel` widgets — with uniform layout, label/help/error placement, and scope badge (global/project). Co-located CSS per component following the extraction conventions: `--duration-*` tokens for any animation (never `--transition-*` as a duration), canonical `--text-muted` (FN-4286 guard), no additions to monolith stylesheets; the existing `animation-duration-tokens.css.test.ts` sweep must stay green.
+- **Test scenarios:**
+  - Each primitive renders label/value/help and propagates change events with the right type.
+  - Null-clear interaction emits the null-as-delete signal (preserving the modal's clear semantics).
+  - CSS sweep test stays green over the new files; no banned tokens.
+- **Test expectation note:** visual polish is verified in U9's browser pass; unit scope here is behavior + tokens.
+- **Verification:** Component tests green; lint (including i18n and CSS guards) green.
+
+### U9. SettingsModal redesign: section-by-section rebuild
+
+- **Goal:** SettingsModal becomes a thin shell over per-section components built from U8 primitives; moved settings disappear behind redirect stubs; everything else behaves identically.
+- **Requirements:** R9, R10, R11
+- **Dependencies:** U4, U5, U8
+- **Files:** `packages/dashboard/app/components/SettingsModal.tsx`, `packages/dashboard/app/components/SettingsModal.css`, `packages/dashboard/app/components/settings/sections/` (new per-section components + CSS), `packages/dashboard/app/hooks/useAppSettings.ts`, `packages/dashboard/app/__tests__/SettingsModal.test.tsx`
+- **Approach:** Keep the proven shell mechanics — `SETTINGS_SECTIONS` nav model with group headers, `visibleSections` gating, save-splitting via `isGlobalSettingsKey`/`isProjectSettingsKey`, null-as-delete, changed-only project writes — but extract each section into a descriptor-driven component under `settings/sections/`. Remove moved settings from their sections; where a section's content moved wholesale (per-phase model lanes, step-execution and review knobs), render a redirect stub row that opens the workflow editor with the Settings panel pre-selected via a query/hash param (e.g. `?panel=settings`, read by `WorkflowNodeEditor` on mount — deterministic and testable), targeting the project's default workflow (one release, per KTD-5). Target IA for the regroup (group headers → sections): **Account** (Authentication); **Global** — General, Appearance, Models & Providers (merging global-models + openrouter + onboarding), Notifications (ntfy/webhook/failure), Research, Remote Access & Node Sync (merging remote + node-sync), Experimental; **Runtimes** unchanged; **Project** — General, Commands & Scripts, Git & Worktrees, Scheduling & Capacity, GitHub Integration, Agents & Permissions, Memory & Backups, Research, Secrets, Plugins. Former project-models and review/step sections collapse into redirect stubs under Project. Section renames keep stable section `id`s where a section survives so deep links and `DEFAULT_SETTINGS_SECTION` stay valid. Device-local three-tier prefs (theme/language/font scale) keep their hooks untouched. The 7,900-line file shrinks to shell + imports.
+- **Execution note:** Land section-by-section in reviewable slices rather than one mega-commit — this is the branch most exposed to the extraction-vs-semantics merge hazard; if `main` changes a setting's behavior mid-flight, port the semantic change to the section's new home and run the union suite.
+- **Test scenarios:**
+  - Save-split regression: editing one global + one project setting in the same session produces the same `updateGlobalSettings`/`updateSettings` patches as before the redesign (characterization of the split function).
+  - Clearing a project override emits null-as-delete; untouched inherited values are not written (changed-only gate preserved).
+  - Moved-setting sections render redirect stubs with a working link to the workflow editor; no moved key is renderable or savable anywhere in the modal.
+  - Section visibility gating (remote/research/evals) unchanged.
+  - i18n: all new strings `t()`-wrapped (lint-enforced); language switch re-renders section labels.
+  - Three-tier prefs still hydrate/write-through (theme toggle round-trip).
+- **Verification:** Dashboard suites + lint green; browser walkthrough of every section (fresh bundle, free port — never 4040) confirming layout, save, clear, and stub navigation.
+
+### U10. End-to-end characterization, docs, and parity closure
+
+- **Goal:** Prove the whole move is behavior-preserving and leave the documentation trail.
+- **Requirements:** R3, R6, R7
+- **Dependencies:** U1-U9
+- **Files:** `packages/core/src/__tests__/workflow-settings-e2e.test.ts` (new), `docs/` user-facing settings/workflow docs, `CONCEPTS.md`
+- **Approach:** One end-to-end suite that runs the canonical journey: pre-migration project with customized moved keys → migration → engine run consuming identical effective values → value edited via panel/tool → engine run consuming the new value → export v2 → wipe → import → same effective values. Update user docs for "where did my setting go" and the workflow-settings authoring story; CONCEPTS.md gains the Workflow Setting / Effective Settings vocabulary.
+- **Test scenarios:**
+  - The full journey above as a single deterministic test (in-memory store, fake timers, no real polling).
+  - Surface enumeration check (FN-5893 discipline): engine, dashboard modal, workflow editor, CLI, agent tools, export/import, sync — each surface has at least one assertion touching workflow settings.
+- **Verification:** Full relevant suites green via `pnpm test` (scoped packages); docs reviewed.
+
+---
+
+## Risks & Dependencies
+
+- **Default re-injection trap (highest severity).** If schema removal and migration ever separate, saved defaults silently overwrite migrated values. Mitigated by single-commit rule (U4) and the dedicated regression test.
+- **Concurrent tracks.** The step-inversion plan (2026-06-04-001) also touches built-in IRs, `SCHEMA_VERSION`, and the workflow editor. Coordinate schema-version numbering and built-in IR edits; whichever lands second rebases the version bump and re-runs the literal sweep.
+- **Long-lived branch vs `main` settings changes.** The SettingsModal rebuild collides with any concurrent settings semantics change. Mitigation: section-by-section slices (U9 execution note), union test suite on conflict.
+- **Multi-node fleets mid-migration.** Nodes migrate independently; the tombstone sync filter prevents cross-contamination, but workflow setting values diverge across nodes until the sync follow-up ships. Surfaced in the sync UI (KTD-8); accepted for this round.
+- **Engine `vi.mock("@fusion/core")` drift.** New core exports (settings types/resolver) break hand-written core mocks in CI shards; sweep mocks when adding exports.
+- **Moved-key catalog disputes.** If implementation reveals a key with readers outside per-task execution (e.g. a scheduler reading `maxParallelSteps` outside task scope), the key stays put and the catalog shrinks — the tombstone list is the single place to amend, and the consistency test enforces coherence.

Subject: [PATCH 012/112] Fix Settings plugin installs registering unloadable
 directory paths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Plugins installed from Settings → Built-in Plugins registered the
manifest directory as the plugin path, but since FN-4128 the loader
requires a loadable entry FILE (Node ESM cannot import directories),
so enabling failed with "Plugin entry must be a file, got directory".
Only the CLI startup path had been migrated to entry-file resolution,
which is why CLI-auto-installed plugins worked and Settings installs
never did.

- Add resolvePluginEntryPath (bundled.js → dist/index.js →
  src/index.ts) to @fusion/core; the CLI keeps its local copy (its
  test fs mocks don't reach externalized core) with sync comments
  both ways.
- Register the resolved entry file in both dashboard install routes;
  400 with a clear message when a package has no loadable entry.
- Heal legacy directory-path registrations on enable, mirroring the
  CLI's startup heal, so existing broken rows recover from the UI
  without a restart.
- Route tests: assert installs register entry files, cover the
  enable-route heal, and update existing install tests to the
  entry-file contract.

 - The "Graph editor" button now actually shows the editor: its overlay was rendered without the `open` class, leaving it `display: none`, so opening it looked like the workflow steps view was just dismissed.
 - `fusion-plugin-compound-engineering` and `fusion-plugin-roadmap` are now listed in the dashboard's built-in plugins, so they appear under Settings → Built-in Plugins (they were implemented and registered but missing from the list).
 - Installing Compound Engineering (and CLI Printing Press) from Settings → Built-in Plugins no longer fails with "Plugin manifest not found": both ids are now in the dashboard's bundled-plugin fallback set, and the Compound Engineering plugin is staged into `dist/plugins/` so packaged installs can resolve it.
+- Plugins installed from Settings now load instead of erroring with "Plugin entry must be a file, got directory": the dashboard install routes register the plugin's loadable entry file (`bundled.js`/`dist/index.js`/`src/index.ts`) rather than the package directory, and enabling a plugin heals legacy directory-path registrations in place.

+## Follow-up failure: directory registered as plugin path
+
+Fixing the fallback surfaced a second, independent bug: both dashboard install routes registered the **manifest directory** as the plugin path, but since FN-4128 the loader requires a loadable entry **file** (Node ESM cannot import directories) — enable then failed with `Plugin entry must be a file, got directory: <dir>`. Only the CLI startup path had been migrated to `resolvePluginEntryPath` (`bundled.js` → `dist/index.js` → `src/index.ts`), which is why CLI-auto-installed plugins worked and Settings-installed ones never did. Fix: the install routes now resolve and register the entry file (helper added to `@fusion/core`), and the enable route heals legacy directory-path rows in place — mirroring the CLI's startup heal.
+
 ## Why This Works
 
 The Settings card sends a relative `./plugins/<id>` path. The server resolves it against `process.cwd()` — normally the user's project dir, not the Fusion repo — so it 404s and falls back to `extractBundledPluginId()`, which only recognizes ids in routes.ts's `BUNDLED_PLUGIN_IDS`. Adding the id makes the fallback resolve the staged bundled copy; the tsup staging block guarantees that copy exists in packaged installs.

Subject: [PATCH 015/112] Address PR review feedback (#1428)

- Add heal block to createPluginRouter's enable handler so it matches
  routes.ts (directory-path registrations re-pointed at entry files)
- Test the 400 "no loadable entry file" install branch
- Add a real-fs drift-guard test asserting the CLI and @fusion/core
  copies of resolvePluginEntryPath resolve identically

Subject: [PATCH 016/112] Tighten plugin install route tests to full
 entry-resolution contract (#1428)

- Bundled fallback assertions for dependency-graph/reports now require
  the bundled.js entry-file suffix instead of just containing the id
- Add route-level fallback cases for dist/index.js and src/index.ts

+ * Workflows declare typed settings ({@link WorkflowSettingDefinition}); setting

+ * validation core that the store write authority

+ *
+ * Two operations:
+ *  - {@link validateSettingValuePatch} — validate a `Record<string, unknown>`
+ *    patch against a setting schema, normalizing accepted values. `null`/`undefined`
+ *    in the patch is a delete sentinel for that setting (always accepted).
+ *  - {@link resolveEffectiveSettingValues} — compose stored values + declaration
+ *    defaults into the effective value map, implementing DROP-ON-ORPHAN (KTD-6).
+ *
+ * KTD-6 — DELIBERATE DIVERGENCE FROM `task-fields.ts`. The custom-field reconciler
+ * (`reconcileFieldsOnWorkflowChange`) RETAINS orphaned values and surfaces them in
+ * a UI disclosure — safe for display data. Workflow settings are POLICY the engine
+ * consumes (a retyped enum→number setting with a stale string value would feed
+ * garbage into execution), so effective resolution DROPS any stored value that no
+ * longer validates against the current declaration and falls to the declaration
+ * `default`. The dropped raw values never reach the engine; the editor surfaces

+# feat: Workflow editor consolidation — primary entry, step migration, import/export, AI design
+
+## Summary
+
+Make the graph node editor the single workflow surface: the header/mobile entry opens it directly and the legacy `WorkflowStepManager` is retired; legacy `WorkflowStep` records auto-migrate into a template library (fragments + a combined default workflow); workflow creation gains a template picker; workflows and templates round-trip as JSON files; and an in-editor "design with AI" affordance plus verified agent-tool exposure make workflows fully agent-authorable. Engine execution semantics are untouched.
+
+---
+
+## Problem Frame
+
+The node editor is feature-rich (cards, success/failure edges, auto-layout, dialogs — plan 002) but buried: the Header's "Workflow Steps" button opens the legacy flat-steps `WorkflowStepManager`, and the graph editor is only reachable through a hand-off button inside it. Two parallel models confuse users: flat per-step records with `enabled`/`defaultOn` flags feeding per-step checkboxes in `TaskForm`, versus graph `WorkflowDefinition`s selected per task. Steps authored in the legacy screen have no representation in the editor; built-ins are the only "templates"; nothing imports or exports; and although `fn_workflow_*` agent tools exist in the executor, there is no user-facing AI authoring affordance and chat/planning-agent exposure is absent (they pass no workflow tools today).
+
+---
+
+## Scope Boundaries
+
+### In scope
+- Entry-point rewire (Header desktop + overflow, MobileNavBar) → node editor; full retirement of `WorkflowStepManager`.
+- Steps→IR converter; idempotent migration of user-authored steps into fragments + a combined default workflow; `kind` discriminator on workflow definitions.
+- Template picker on workflow creation; dynamic palette templates (fragments, built-in step templates, plugin-contributed step templates); safe fragment insertion.
+- JSON import/export for workflows and fragments (built-ins exportable), with approval-flag stripping at the write boundary.
+- `POST /api/workflows/design` AI endpoint + in-editor affordances; wire `fn_workflow_*` into chat/planning lanes via `customTools`.
+- Workflow-centric `TaskForm`: per-step checkboxes replaced by a workflow picker, with a create-time `workflowId` path.
+
+### Deferred to Follow-Up Work
+- Removing the `WorkflowStep` records/routes/engine path itself — steps remain the compiled execution substrate (`materializeWorkflowSteps`, `enabledWorkflowSteps`); only their authoring UI is retired.
+- Per-node "Refine with AI" inside the editor inspector (the legacy manager's refine button dies with it; whole-graph AI design covers v1).
+- AI design retry/repair loops and streaming/detached turns (sync v1; upgrade path noted in KTD-6).
+- Cross-project template gallery beyond file import/export; workflow versioning/history.
+- Mobile-optimized canvas authoring.
+- Schema-level rejection of trust-escalating config fields in `parseWorkflowIr` (point-fixed at import/design boundaries here; systemic enforcement is a follow-up).
+
+### Outside this product's identity
+- Changing how compiled steps execute, the seam model, or `parseWorkflowIr`/compiler semantics. Migration and import produce artifacts the existing validators accept; they never relax validation.
+
+---
+
+## Requirements
+
+**Entry & consolidation**
+- R1 — The Header button (desktop + overflow) and MobileNavBar item open the node editor directly; labels say "Workflows". No surface routes through the legacy manager.
+- R2 — `WorkflowStepManager` is fully removed: component, tests, `useModalManager` state (`workflowStepsOpen`/`open`/`close`, `anyModalOpen` membership), `onOpenGraphEditor` hand-off, and `App.tsx`/`AppModals.tsx` wiring. `/api/workflow-steps` routes and step records remain (execution substrate). Removal lands only after R3's picker has replaced the per-step checkboxes (no release window with neither surface).
+- R3 — `TaskForm`'s per-step checkbox list is replaced by a workflow picker: project default preselected and badged "(default)"; "No workflow" listed first; built-ins + user workflows (fragments excluded); loading placeholder while definitions fetch; helper text explains what the selected workflow runs. Selection is applied at create time via a new `workflowId` create parameter materialized server-side inside the task-creation transaction (see KTD-4). An empty/new project shows a CTA into the editor.
+
+**Templates & migration**
+- R4 — A pure steps→IR converter produces a valid v1 IR from a `WorkflowStep[]` (seams encoded per the `linear()` convention; `phase` honored, with undefined phase mapping to pre-merge; the merge seam always emitted); compiling the produced IR yields steps equivalent to the input over all compiler-visible fields (round-trip parity).
+- R5 — On first editor open per project, user-authored steps (excluding `WORKFLOW_COMPILED_STEP_TEMPLATE_PREFIX`-tagged rows) migrate idempotently: **every** user step (enabled or not) → a single-node fragment; the **defaultOn** set → one combined "Migrated steps" workflow; when that set is non-empty the migrated workflow becomes the project default (preserving "new tasks run these" behavior). Enabled-but-optional steps remain available as fragments. Source steps are marked migrated; re-runs and concurrent opens create no duplicates. After a migration that produced anything, the editor shows a one-time dismissible notice explaining where steps went, and the migrated workflow carries a system description ("Converted from your legacy workflow steps").
+- R6 — Workflow definitions carry `kind: "workflow" | "fragment"`; fragments never appear in task workflow pickers, default-workflow selection, or compile/selection paths.
+- R7 — Workflow creation offers a template picker: blank, built-in workflows, and user workflows as starting points — copies with fresh IDs, never references. Each entry shows name, description, and node count; the copy's default name is the source name + " copy" and inherits the source description. With no user workflows, the picker shows blank + built-ins only.
+- R8 — The editor palette gains a Templates section grouped into Fragments / Built-in steps / Plugin steps subsections (alphabetical within groups; a filter input appears when the combined list exceeds 8 entries; plugin entries carry the owner badge). Entries insert pre-configured nodes; insertion remaps node IDs and pre-validates seam duplication, surfacing conflicts as a persistent inline error in the palette section.
+
+**Import/export**
+- R9 — Any workflow or fragment (including built-ins) exports as a JSON envelope (format marker, schema version, kind, name, description, ir, layout) via file download. Export is disabled while the canvas is dirty (tooltip: save first); the export affordance notes that files contain full prompt/command text.
+- R10 — Import validates the envelope and IR server-side at the write boundary; always mints a fresh ID (stripping `builtin:`); suffixes the name on collision; **strips `cliSkipApproval`/`autoApprove` from all node configs** (flagged in the response so the UI can notify); rejects IRs referencing unavailable traits/columns with a message naming the missing trait; warns (without blocking) when a script node's `scriptName` is absent from the target project. Envelopes with `schemaVersion` ≤ the server's are accepted; newer are rejected with a version message. Invalid files never persist partial state. Validation failures render as a persistent inline error near the import affordance (not a toast); the file input resets either way.
+
+**AI & agents**
+- R11 — "Design with AI" takes a prompt (and, for the edit flow, the persisted workflow read server-side by ID — the client never posts IR) and returns a server-validated IR with the same approval-flag stripping as import; failures and interpreter-only results reuse the existing banner triage; the canvas is never replaced without the dirty guard, and never on failure. The affordance shows an in-flight state (disabled control + spinner + `aria-busy`) and a client-side cancel; the route is rate-limited like the other AI routes.
+- R12 — `fn_workflow_create/update/delete/list/get/select` are verifiably exposed to the task executor (existing), and to chat and planning lanes via `createFnAgent`'s `customTools`, with a guard test asserting all six tool names per lane.
+
+---
+
+## Key Technical Decisions
+
+- KTD-1 — **Fragments are `WorkflowDefinition`s with a `kind` column, stored as parseable full IRs.** Add `kind TEXT NOT NULL DEFAULT 'workflow'` to `workflows` (`addColumnIfMissing`, SCHEMA_VERSION 108→109). A fragment's IR is a normal `start → nodes → end` v1 graph so `parseWorkflowIr` validates it unchanged; insertion strips `start`/`end` and remaps IDs. `createWorkflowDefinition` gains `input.kind` in both the definition object and the INSERT column list; fragment IRs are pure v1 so `downgradeIrToV1IfPure` leaves them intact. **Caching:** `listWorkflowDefinitions` keeps caching the full merged set; the `kind` filter applies to the returned slice after the cache read — never cache a filtered result (the single unconditional cache would otherwise poison unfiltered consumers).
+- KTD-2 — **Steps→IR converter is the literal inverse of the compiler, proven by round-trip — and its blind spots are named.** New pure `stepsToWorkflowIr(steps)` in `@fusion/core` inverts `nodeToStepInput` field-by-field and encodes seams exactly as `linear()` does. Parity covers exactly the compiler-visible fields (`name/mode/phase/gateMode/prompt/scriptName/toolMode/modelProvider/modelId`); `enabled`/`defaultOn`/`templateId` are **not** compiler-visible and are handled by migration policy (KTD-3), not the converter. Undefined `phase` maps to pre-merge; the merge seam is always emitted. A comment at both `nodeToStepInput` and the converter requires extending parity when fields are added.
+- KTD-3 — **Migration is lazy, server-side, marker-idempotent — and preserves defaultOn semantics via the project default.** `POST /api/workflows/migrate-legacy-steps` runs on first editor open inside `transactionImmediate` (write lock before the unmigrated-rows SELECT, matching `selectTaskWorkflow`'s pattern); each source row is stamped with `migratedFragmentId`. Representation policy: every user step → fragment (composable reuse in the palette); the **defaultOn** subset → the combined "Migrated steps" workflow (these were the steps that ran automatically on new tasks); if that subset is non-empty the migrated workflow is set as the project default so new-task behavior is preserved. Enabled-but-optional steps deliberately do NOT join the combined workflow — their per-task opt-in granularity maps to "insert the fragment" or "pick a different workflow", not to always-on execution. The combined workflow is a migration-continuity artifact (the TaskForm landing path for legacy users); fragments are the reusable pieces — that division is the payoff of the dual representation.
+- KTD-4 — **TaskForm goes workflow-centric with a create-time `workflowId` parameter (user decision + feasibility correction).** `selectTaskWorkflow` requires an existing task ID and is NOT reusable at create time; instead, task-create input gains `workflowId?: string`, and the store materializes the selection inside the same task-creation transaction (mirroring the existing `materializeDefaultWorkflowSteps` + `pendingWorkflowSelection` + `writeTaskWorkflowSelection` default-workflow block at store.ts ~3974-4035). No create-then-select window exists, so the executor can never pick up a task with the wrong step set. `enabled`/`defaultOn` flags stop being user-facing.
+- KTD-5 — **Import/export follows the Settings JSON pattern with a versioned envelope and trust-boundary stripping.** Client: `createObjectURL` download / `FileReader` upload. Server: `POST /api/workflows/import` validates envelope marker + schema version (≤ current accepted; newer rejected) + `parseWorkflowIr` + trait availability before any write; strips `cliSkipApproval`/`autoApprove` from node configs (these flags bypass the CLI first-run approval gate — the only user-visible gate on arbitrary command execution — and must not survive an untrusted file boundary); collision policy = fresh ID always, name suffix ` (imported)`.
+- KTD-6 — **AI design reuses the refine-route pattern — synchronous, output-extracted, validated, stripped, canvas-safe, rate-limited.** `POST /api/workflows/design` constructs a one-shot tool-less agent via the `createFnAgent` DI seam (module-level `__setCreateFnAgentForDesign` co-located with the route), planning-lane model, system prompt that emits IR JSON (vocabulary per `fn_workflow_create`'s description). The accumulated text passes through the repo's existing JSON-from-text extraction helper (planning/agent-generation precedent — models fence and wrap JSON) before `parseWorkflowIr` + compile triage (interpreter-only via the message-suffix convention) + approval-flag stripping. For the edit flow the route takes a `workflowId` and reads the persisted IR from the store — the client never posts IR (removes the injection vector and matches how compile/selection routes work). Rate-limited 10/hour like `/ai/refine-text`. A detached-turn upgrade (observable-long-running pattern) is the documented path if design ever grows tools.
+- KTD-7 — **Agent exposure is wired via `customTools`, not assumed.** `fn_workflow_*` live only in the task executor's toolset today; chat (`tools: "coding"`, no customTools) and planning (`customTools: createPlanningBoardTools`) gain the workflow tool factories through `createFnAgent`'s `customTools` option with a scoped store handle. A guard test asserts all six tool names per intended lane. Tool handlers parse args defensively (string-JSON accepted).
+- KTD-8 — **Plugin step templates surface as a palette subsection.** The editor fetches `WORKFLOW_STEP_TEMPLATES` + the plugin template registry (client fn `fetchPluginWorkflowStepTemplates` already exists — currently consumed by the manager; it survives U3's deletion) and renders preset single nodes with config prefilled via the converter's field mapping.

+
+## Implementation Units
+
+### U1. `kind` discriminator + steps→IR converter (core)
+
+**Goal:** Storage and conversion foundations: fragments distinguishable from workflows; a proven inverse of the compiler.
+**Requirements:** R4, R6.
+**Dependencies:** none.
+**Files:**
+- `packages/core/src/db.ts` (modify) — `kind` column on `workflows`, `migratedFragmentId` column on `workflow_steps` (both `addColumnIfMissing`); `SCHEMA_VERSION` 108→109.
+- `packages/core/src/workflow-definition-types.ts` (modify) — `kind` on `WorkflowDefinition`/`Input`.
+- `packages/core/src/store.ts` (modify) — `createWorkflowDefinition` accepts `input.kind`, includes it in the definition object AND the INSERT column list (default `workflow`); confirm fragment IRs survive `downgradeIrToV1IfPure`; `listWorkflowDefinitions({ kind? })` filtering the returned slice AFTER the cache read (cache always holds the full merged set); fragments excluded from task-selection/default-workflow consumers; `selectTaskWorkflow` rejects fragment IDs.
+- `packages/core/src/workflow-steps-to-ir.ts` (new) — `stepsToWorkflowIr(steps, name)`, `stepToFragmentIr(step)`; inverse of `nodeToStepInput`; seams per `linear()`; undefined phase → pre-merge; parity-extension comments at both sites.
+- `packages/core/src/index.ts` (modify) — re-exports.
+- `packages/core/src/__tests__/workflow-steps-to-ir.test.ts` (new), `packages/core/src/__tests__/workflow-definition-store.test.ts` (extend).
+**Approach:** Additive, forward-only migration. Fragment IRs are full parseable graphs (KTD-1). Converter is pure, no I/O.
+**Patterns to follow:** `addColumnIfMissing` (db.ts ~3795); `linear()` builder; `compileWorkflowToSteps`/`nodeToStepInput` as the inversion source of truth.
+**Test scenarios:**
+- Covers R4: round-trip parity — mixed pre/post-merge steps with prompt/script/gate modes, model overrides, toolMode → `compileWorkflowToSteps(stepsToWorkflowIr(steps))` reproduces every compiler-visible field.
+- All-phase-undefined step set → parseable IR with the canonical seam pipeline; round-trips to phase `pre-merge`.
+- Produced IR passes `parseWorkflowIr`; seams once each, execute→review→merge order, seam `failure → end` edges.
+- Empty step list → minimal valid IR; post-merge-only set → nodes after the merge seam.
+- `stepToFragmentIr` → `start → node → end`, parseable, config mirrors the step.
+- Covers R6: kind=fragment persists and round-trips (INSERT includes kind); `listWorkflowDefinitions({kind:"fragment"})` returns only fragments; calling filtered-then-unfiltered (and reverse) returns correct sets both times (cache-poisoning regression); task-selection list excludes fragments; `selectTaskWorkflow(fragmentId)` rejects; fragment IR unchanged by `downgradeIrToV1IfPure`.
+- Migration 109 applies on a v108 DB and is idempotent on re-run.
+
+### U2. Lazy idempotent step migration (server + core)
+
+**Goal:** Existing user steps become fragments + a combined default workflow, exactly once per project, with user awareness.
+**Requirements:** R5.
+**Dependencies:** U1.
+**Files:**
+- `packages/core/src/store.ts` (modify) — `migrateLegacyWorkflowSteps()`: `transactionImmediate` (write lock before the unmigrated-rows SELECT); every unmigrated user step → fragment; defaultOn subset → combined "Migrated steps" workflow with the system description; sets project default workflow when that subset is non-empty; stamps `migratedFragmentId`.
+- `packages/dashboard/src/routes/register-workflow-routes.ts` (modify) — `POST /api/workflows/migrate-legacy-steps` returning `{migrated, skipped, combinedWorkflowId?}`.
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — fire the migration call once on editor open (refetch list after); non-fatal on error (404 tolerated if the route ships later); when `migrated > 0`, show a one-time dismissible notice (persisted dismissal, localStorage) explaining where steps went.
+- `packages/dashboard/src/routes/__tests__/workflow-migrate-route.test.ts` (new), `packages/core/src/__tests__/workflow-step-migration.test.ts` (new).
+**Approach:** KTD-3 representation policy. No deletion of step records. Zero user steps → no-op, no combined workflow, no notice.
+**Execution note:** exercise the real store seam in route tests — do not mock store methods the route depends on (mock-masked dead-wiring learning).
+**Test scenarios:**
+- Covers R5: defaultOn + enabled-optional + disabled steps + one compiled-prefixed row → 3 fragments; combined workflow contains ONLY the defaultOn step; project default set to the migrated workflow; compiled row untouched; all sources stamped.
+- No defaultOn steps → fragments created, NO combined workflow, project default unchanged.
+- Second run → `{migrated: 0, skipped: n}`, no new definitions (idempotency).
+- Two sequential invocations racing the marker → definitions created once (transactionImmediate honored).
+- Zero user steps → no-op.
+- Editor: notice shown once when migrated > 0; dismissal persists; absent when migrated = 0.
+
+### U3. Entry rewire + retire WorkflowStepManager
+
+**Goal:** Node editor is the only workflow surface; the legacy manager is gone — with no coverage gap.
+**Requirements:** R1, R2.
+**Dependencies:** U1, U6 (the TaskForm picker must land before or with the manager's removal — no release window where users can neither author steps nor pick workflows). U2 must merge before release so the editor's migrate call has a route, but does not gate this unit's landing (the call is non-fatal).
+**Files:**
+- `packages/dashboard/app/components/Header.tsx` (modify) — button (~1601) + overflow item (~1947) → `openWorkflowEditor`, label `t("header.workflows", "Workflows")`.
+- `packages/dashboard/app/components/MobileNavBar.tsx` (modify) — more-menu item (~592) → editor.
+- `packages/dashboard/app/hooks/useModalManager.ts` (modify) — remove `workflowStepsOpen`/`openWorkflowSteps`/`closeWorkflowSteps` + `anyModalOpen` membership.
+- `packages/dashboard/app/App.tsx`, `packages/dashboard/app/components/AppModals.tsx` (modify) — drop wiring + `onOpenGraphEditor`.
+- `packages/dashboard/app/components/WorkflowStepManager.tsx` + `.css` + tests (delete). The `fetchPluginWorkflowStepTemplates`/`fetchWorkflowStepTemplates` client fns it consumed live in `app/api` and survive (consumed by U9).
+- `packages/dashboard/app/components/__tests__/AppModals.test.tsx`, Header/MobileNavBar tests (modify).
+**Approach:** Surface Enumeration: Header desktop, Header overflow, MobileNavBar more-menu, AppModals mount, useModalManager state + `anyModalOpen`, App.tsx props, `onOpenGraphEditor`. `/api/workflow-steps` routes, the refine route, and `WORKFLOW_STEP_TEMPLATES` exports stay.
+**Test scenarios:**
+- Covers R1: Header button opens the node editor; desktop + overflow + mobile more-menu.
+- Covers R2: no `WorkflowStepManager` references remain; `anyModalOpen` correct with the editor open; `openWorkflowSteps` no longer exported (type-level).
+- Mobile breakpoint: more-menu item opens the editor.
+
+### U4. Template picker on workflow creation (editor)
+
+**Goal:** Creation starts from a previewable template choice.
+**Requirements:** R7.
+**Dependencies:** U1 (kinds); U8 (shares fresh-ID copy helpers).
+**Files:**
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — create dialog gains a template step: a focus-trapped option list (arrow-key navigable; each entry shows name, description, node count) of blank / built-ins / user kind=workflow definitions; selecting seeds a fresh-ID copy (name = source + " copy", description inherited).
+- `packages/dashboard/app/components/WorkflowNodeEditor.css` (modify).
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (extend).
+**Approach:** Copies via the U8 ID-remap helpers applied to the whole graph. With no user workflows: blank + built-ins only. The migrated workflow appears with its system description.
+**Test scenarios:**
+- Covers R7: create-from-builtin seeds a copy (fresh IDs, same node count, name "X copy", description inherited); builtin stays read-only; blank unchanged.
+- Picker entries render name/description/node count; empty-user-workflow state lists blank + builtins.
+- Fragments never appear in the picker.
+- Keyboard: arrow navigation + Enter selects (a11y).
+
+### U5. Import/export (server + editor)
+
+**Goal:** Workflows and fragments round-trip as files, safely.
+**Requirements:** R9, R10.
+**Dependencies:** U1.
+**Files:**
+- `packages/dashboard/src/routes/register-workflow-routes.ts` (modify) — `GET /api/workflows/:id/export`, `POST /api/workflows/import` per KTD-5 (strip approval flags + response flag; scriptName warning; version gate ≤ current).
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — Export button (disabled while dirty, tooltip "Save to export"; enabled for built-ins; tooltip notes files contain full prompt/command text), Import affordance (sidebar; keyboard-accessible trigger for `<input type="file" accept=".json">`; persistent inline error region for validation failures; toast only for network errors; input resets after any attempt; notice when approval flags were stripped).
+- `packages/dashboard/app/api/legacy.ts` (modify) — client fns.
+- `packages/dashboard/src/routes/__tests__/workflow-import-export.test.ts` (new), `__tests__/WorkflowNodeEditor.test.tsx` (extend).
+**Approach:** Envelope per HTD. Server is the sole validator. Export reads the persisted definition (dirty-guard makes stale export impossible).
+**Test scenarios:**
+- Covers R9: export → import reproduces ir/layout/description semantically; fragment kind preserved; export blocked while dirty (button disabled).
+- Covers R10: name collision → suffixed; builtin export → fresh non-builtin editable ID; missing envelope marker → 400; malformed IR → 422 + parser message, zero writes; unknown trait → 422 naming the trait; `schemaVersion` older → accepted; newer → 409 version message; CLI node with `cliSkipApproval: true` → persisted node lacks the field and the response flags the strip; script node with unknown scriptName → 200 + warning field.
+- Editor: validation failure renders the inline error (not a toast) and the list is unchanged; success refreshes + activates; strip notice shown when flagged.
+
+### U6. Workflow-centric TaskForm + create-time workflowId
+
+**Goal:** Tasks pick a workflow, applied atomically at creation.
+**Requirements:** R3.
+**Dependencies:** U1 (fragment exclusion). (U2's migrated workflow appears automatically once present — runtime ordering, not a build dependency.)
+**Files:**
+- `packages/core/src/types.ts` + `packages/core/src/store.ts` (modify) — `workflowId?: string` on the task-create input; materialization inside the creation transaction mirroring the default-workflow block (`materializeDefaultWorkflowSteps`/`pendingWorkflowSelection`/`writeTaskWorkflowSelection`, store.ts ~3974-4035); explicit `workflowId` overrides the project default; fragment IDs rejected.
+- `packages/dashboard/src/routes` task-create route (modify) — accept + pass `workflowId`.
+- `packages/dashboard/app/components/TaskForm.tsx` (modify) — replace the per-step checkbox section (~280, ~330-339, ~1331-1337) with the workflow dropdown (states per R3); remove `fetchWorkflowSteps` usage; empty-workflow-list CTA into the editor.
+- `packages/dashboard/app/components/__tests__/` TaskForm tests (extend), `packages/core/src/__tests__/` task-create tests (extend).
+**Approach:** The engine path is untouched — materialization writes `enabledWorkflowSteps` exactly as the default-workflow path does, in the same transaction, so no executor-pickup race exists. `selectTaskWorkflow` remains the post-create path only.
+**Test scenarios:**
+- Covers R3: create with `workflowId` → task's `enabledWorkflowSteps` populated within the creation write (no intermediate empty state observable); explicit pick overrides project default; "No workflow" → no custom steps; fragment ID → rejected.
+- Dropdown: loading placeholder; "(default)" badge on the project default; "No workflow" listed first; fragments absent; built-ins present.
+- Empty project → CTA opens the editor.
+- Regression: per-step checkboxes gone; no `fetchWorkflowSteps` call remains in TaskForm.
+
+### U7. AI design route (server)
+
+**Goal:** Prompt → validated, stripped, rate-limited IR.
+**Requirements:** R11 (server half).
+**Dependencies:** U1.
+**Files:**
+- `packages/dashboard/src/routes/register-workflow-routes.ts` (modify) — `POST /api/workflows/design` `{prompt, workflowId?}` per KTD-6: module-level `__setCreateFnAgentForDesign` DI seam co-located with the route; planning-lane model; tool-less; JSON-from-text extraction via the existing helper (planning/agent-generation precedent); `parseWorkflowIr` + compile triage (`interpreterOnly` flag) + approval-flag stripping; `workflowId` read from the store (client never posts IR); rate limit 10/hour mirroring `/ai/refine-text`; bounded prompt length.
+- `packages/dashboard/src/routes/__tests__/workflow-design-route.test.ts` (new).
+**Execution note:** route tests use the DI seam with a fake agent — no real model calls.
+**Test scenarios:**
+- Covers R11: fake agent returns valid linear IR → 200 `{ir, interpreterOnly:false}`; branching IR → 200 `{interpreterOnly:true}`; fenced/prose-wrapped JSON → still extracted and 200; invalid JSON / IR failing `parseWorkflowIr` → 422 + message, nothing persisted; IR containing `cliSkipApproval` → returned IR lacks it + strip flag set.
+- `workflowId` flow: route reads the persisted IR; unknown ID → 404.
+- Rate limit: 11th call within the window → 429.
+- Over-length prompt → 400.
+
+### U8. Fragment insertion + graph-copy helpers (mapping layer)
+
+**Goal:** Pure, tested primitives for inserting fragments and copying graphs.
+**Requirements:** R8 (helper half), R7 (copy helpers).
+**Dependencies:** U1.
+**Files:**
+- `packages/dashboard/app/components/workflow-flow-mapping.ts` (modify) — `insertFragment(nodes, edges, fragmentIr, position)` (strips start/end, remaps all node IDs to fresh `newNodeId`s, rewires internal edges), `fragmentSeamConflicts(fragmentIr, nodes)`, `copyIrWithFreshIds(ir, layout)`.
+- `packages/dashboard/app/components/__tests__/workflow-flow-mapping.test.ts` (extend).
+**Approach:** Pure-helper-first so jsdom limits don't bite; consumed by U4 (copies) and U9 (palette insertion).
+**Test scenarios:**
+- Covers R8: `insertFragment` remaps every node ID (no collisions), strips start/end, preserves internal edges/config; double-insert → disjoint ID sets.
+- Fragment containing a `merge` seam vs a graph that has one → `fragmentSeamConflicts` flags it.
+- `copyIrWithFreshIds` → same structure, all-new IDs, layout keys remapped consistently.
+
+### U9. Palette Templates section (editor)
+
+**Goal:** The template library is insertable from the palette.
+**Requirements:** R8.
+**Dependencies:** U1, U8. (U2's fragments appear once migrated — runtime ordering.)
+**Files:**
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — Templates palette section: Fragments / Built-in steps / Plugin steps subsections (alphabetical; filter input when combined > 8; plugin owner badges); entries keyboard-activatable (Enter/Space) with descriptive aria-labels; fragment insertion via U8 with the persistent inline conflict error in the section; preset step nodes via the converter field mapping; section collapsed state persisted.
+- `packages/dashboard/app/api/legacy.ts` (modify) — fragments fetch (kind param); reuse existing `fetchWorkflowStepTemplates`/`fetchPluginWorkflowStepTemplates`.
+- `packages/dashboard/app/components/WorkflowNodeEditor.css` (modify).
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (extend).
+**Test scenarios:**
+- Covers R8: three subsections render with their sources; plugin entry carries owner badge; inserting a step template adds a node with prefilled config; inserting a fragment with a seam conflict → inline error, no insertion; filter input appears above 8 combined entries and filters across groups.
+- Empty fragment library → Fragments subsection hidden.
+- Builtin active → insertion disabled (read-only gating).
+- Keyboard activation inserts (a11y).
+
+### U10. Design-with-AI editor affordances
+
+**Goal:** Prompt-to-workflow UX in both entry points.
+**Requirements:** R11 (client half).
+**Dependencies:** U7.
+**Files:**
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (modify) — create dialog: an optional "Describe it instead" textarea (placeholder with an example prompt) before template selection — submitting designs a new workflow from the result; toolbar: "Design with AI" opens a popover panel (textarea + submit) targeting the active workflow via `workflowId`; proposed replacement applies only through the dirty-guard confirm. In-flight: control disabled + spinner + `aria-busy`, client-side cancel (abort the fetch); failure → server message inline, canvas untouched; `interpreterOnly` → existing info banner on the seeded graph; strip notice when flagged.
+- `packages/dashboard/app/components/WorkflowNodeEditor.css` (modify).
+- `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.test.tsx` (extend).
+**Test scenarios:**
+- Covers R11: mocked design success in create dialog → new workflow seeded from returned IR; toolbar flow over a dirty canvas → discard confirm first, cancel keeps edits.
+- Mocked 422 → inline error, canvas untouched.
+- In-flight state: control disabled, aria-busy set; cancel aborts and re-enables.
+- interpreterOnly result → info banner visible.
+
+### U11. Agent-lane exposure (engine)
+
+**Goal:** Chat and planning agents can author workflows; drift-guarded.
+**Requirements:** R12.
+**Dependencies:** none (independent; lands first safely).
+**Files:**
+- `packages/dashboard/src/chat.ts` (modify, ~1288/1612) — pass `fn_workflow_*` factories via `createFnAgent`'s `customTools` (chat passes none today — introduce the array) with the scoped store.
+- `packages/dashboard/src/planning.ts` (modify, ~842) — append the workflow tool factories to the existing `customTools: [...createPlanningBoardTools(store)]`.
+- `packages/engine/src/__tests__/agent-workflow-tools-exposure.test.ts` (new) — asserts all six names (`fn_workflow_create/update/delete/list/get/select`) per lane: executor, chat, planning.
+- Touched tool handlers (verify) — defensive arg parsing (string-JSON accepted).
+**Approach:** Grep every `fn_workflow_` registration surface first and mirror all hits (drift learning).
+**Test scenarios:**
+- Covers R12: exposure test enumerates executor + chat + planning toolsets and asserts `fn_workflow_create/update/delete/list/get/select` membership in each; fails when any lane loses one.
+- Chat lane: customTools array introduced without disturbing existing chat tool behavior (existing chat tests stay green).
+- A workflow tool invoked with stringified-JSON args still parses.
+
+---
+
+## Risks & Dependencies
+
+- **Migration writes to user DBs.** Additive only (2 columns, new rows, marker stamps, one project-default settings write); `transactionImmediate`; idempotent by stored marker; nothing deleted or rewritten.
+- **defaultOn policy is a behavior interpretation.** Mapping defaultOn → combined-workflow-as-project-default preserves "new tasks run these" but collapses per-task uncheckability into workflow choice + fragments. Named in release notes; the migration test suite pins the policy.
+- **Round-trip fidelity gaps.** Parity covers compiler-visible fields only — by design; `enabled`/`defaultOn`/`templateId` are policy-handled. Extend parity when `nodeToStepInput` gains fields (comments at both sites).
+- **Trust boundary.** `cliSkipApproval`/`autoApprove` bypass the CLI approval gate; import and design strip them (R10/R11). Systemic schema-level rejection is an explicit follow-up. Exported files contain full prompt/command text — disclosure note on the export affordance.
+- **Removal blast radius.** U3's Surface Enumeration is the sweep list; U3 is gated on U6 to avoid the no-surface window.
+- **Import strictness vs. portability.** Unknown traits block (422 naming trait + owning plugin); unknown scriptNames warn without blocking — scripts are project-settings content the user can add after import.
+- **AI output variance.** JSON extraction + server validation bound the failure mode to a clean 422; retry/repair deferred. Synchronous route bounded by rate limit + prompt-length cap; detached-turn upgrade documented.
+- **Registration drift** (agent tools, palette template sources): grep-and-mirror; U11 guard test.
+- **Mid-migration TaskForm state.** A user can open TaskForm before ever opening the editor — they see built-ins (+ any existing workflows) until migration runs on first editor open; acceptable, noted here so it isn't mistaken for a bug.
+- **Changeset:** user-facing feature in the bundled CLI → `@runfusion/fusion` minor changeset.
+
+---
+
+## System-Wide Impact
+
+- **Schema:** SCHEMA_VERSION 108→109 (two additive columns).
+- **Engine:** no execution-semantics change; chat/planning lanes gain workflow tools (additive).
+- **Existing users:** flat steps keep executing on existing tasks; the step-authoring UI is replaced by migrated workflows/fragments; defaultOn behavior is preserved via the migrated project default; TaskForm visibly changes (workflow picker) — release-notes worthy, plus the in-editor one-time migration notice.
+- **Plugins:** contributed step templates move to the editor palette; plugin API unchanged.

 *Avoid:* built-in plugin (as a distinct concept; the Settings label uses "Built-in" for the same thing)
 
 A Bundled Plugin must be registered in several independently maintained surfaces — the Settings catalog, the dashboard server's bundled-id fallback set, the CLI's startup auto-install list, and the build step that stages a loadable copy into the distribution. The surfaces do not cross-check each other: a plugin registered in some but not all appears installable yet fails to install or load, so adding one means mirroring an existing bundled plugin across every surface.
+
+### Plugin Entry
+The single loadable file persisted as a plugin's path and dynamically imported by the loader. The contract is strict: a package directory is never a valid entry (ESM cannot import directories), so every install surface must resolve a concrete file before persisting, preferring the shipped bundle, then a prebuilt output, then raw workspace source. Legacy registrations that stored a directory are healed in place — re-pointed at a resolved entry — the next time the plugin is enabled or auto-installed.

 ## Workflow columns & traits
 
 *Behind the `experimentalFeatures.workflowColumns` flag. With the flag off, the legacy fixed pipeline (the closed column enum + `VALID_TRANSITIONS`) is authoritative and unchanged.*

 ## Follow-up failure: directory registered as plugin path
 
-Fixing the fallback surfaced a second, independent bug: both dashboard install routes registered the **manifest directory** as the plugin path, but since FN-4128 the loader requires a loadable entry **file** (Node ESM cannot import directories) — enable then failed with `Plugin entry must be a file, got directory: <dir>`. Only the CLI startup path had been migrated to `resolvePluginEntryPath` (`bundled.js` → `dist/index.js` → `src/index.ts`), which is why CLI-auto-installed plugins worked and Settings-installed ones never did. Fix: the install routes now resolve and register the entry file (helper added to `@fusion/core`), and the enable route heals legacy directory-path rows in place — mirroring the CLI's startup heal.
+Fixing the fallback surfaced a second, independent bug (fixed in PR #1428): both dashboard install routes registered the **manifest directory** as the plugin path, but since FN-4128 the loader requires a loadable entry **file** (Node ESM cannot import directories) — enable then failed with `Plugin entry must be a file, got directory: <dir>`.

+
+### Trap: vitest fs mocks don't reach externalized workspace deps
+
+Moving `resolvePluginEntryPath` to `@fusion/core` and re-exporting from the CLI broke the CLI's tests: `vi.mock("node:fs")` in the CLI package does **not** intercept fs calls made inside the externalized `@fusion/core` import (vitest only inlines/mocks modules in the test package's transform graph — the dashboard package inlines core, the CLI doesn't). Resolution: the CLI keeps an intentionally duplicated local copy (its fs mocks work against it), both copies carry keep-in-sync comments, and a **real-fs drift-guard test** (`packages/cli/src/plugins/__tests__/resolve-plugin-entry-path-sync.test.ts`) imports both copies and asserts identical resolution across real temp-dir layouts — each candidate alone, precedence pairs, all three, and the no-entry → `null` case. Real directories are the only seam that exercises both implementations equally; a candidate-list change applied to one copy but not the other now fails CI.
 
 ## Why This Works
 
@@ -75,9 +80,13 @@ The Settings card sends a relative `./plugins/<id>` path. The server resolves it
 
 - **When adding a bundled plugin, grep for an existing one** (e.g. `rg -l "fusion-plugin-roadmap" packages/` ) and mirror every hit — that surfaces all four lists plus view registration.
 - Route tests must force the fallback: mock fs so the cwd-relative path **misses** and only `dist/plugins/<id>` exists (see "installs bundled compound engineering plugin when relative path misses cwd" in `packages/dashboard/src/__tests__/plugin-routes.test.ts`). A mock that matches any path containing the plugin id tests nothing.
+- **Pin assertions to the exact contract, not substring containment.** `stringContaining(pluginId)` passed for both the correct entry-file path and the buggy directory path — when a mock or matcher can satisfy both the correct and the buggy value, the test proves nothing. Route tests now assert the registered path ends in an entry-file suffix, cover the `dist/index.js` and `src/index.ts` fallbacks, and the 400 no-entry branch.
+- When duplicating a helper is forced by test infrastructure (fs mocks vs externalized deps), add a real-fs drift-guard test that runs every copy against the same on-disk fixtures and asserts identical output.
 - Consider a future consistency test asserting every `BUILTIN_PLUGINS` UI entry with a `path` is present in both server-side `BUNDLED_PLUGIN_IDS` sets.

+ *
+ * This is what keeps U3 behavior-identical BEFORE the U4 hard-move: a customized
+ * project setting still present in the base is NOT clobbered by a declaration
+ * default; only a real stored workflow value overrides it. After the hard-move the
+ * base lacks the moved key, so the declaration default fills it. Absent-default
+ * model lanes contribute nothing, so they never override a real project value.

 A workflow-declared, typed task field (`string | text | number | boolean | enum | multi-enum | date | url`, with enum options and render hints) whose values live in `tasks.customFields`, keyed by field id. The task model is thereby recast as core fields (title, description) + standard metadata + these workflow-defined fields. Writes pass through a single store authority (`updateTaskCustomFields`) that validates each value against the resolving workflow's schema and returns typed rejections (offending `fieldId` + `code`); agents write them via `fn_task_update`'s `custom_fields` patch. Editing a workflow's fields or switching a task's workflow orphans (never destroys) values for removed or type-incompatible ids — orphans are retained and surfaced under a detail disclosure, excluded from cards. Same id means the same field within a project; there is no cross-workflow shared field namespace.

+### CLI Executor
+The executor type `cli-agent`: a Fusion agent session (task execute step, planning, validator, CE plugin session, or chat) driven by an interactive CLI coding agent running in a Fusion-owned PTY. Distinct from the pre-existing non-interactive `cli` executor kind (the named-script/raw-command runner). Selected on the workflow node for task surfaces (per-task override) and per session for chat/CE. The board lifecycle is unchanged — the terminal is the execution surface, not a separate workflow.

+The per-CLI integration that launches and understands one CLI agent. Native-telemetry adapters (Claude Code, Codex, Droid, Pi) tap the CLI's own hooks/session logs for precise agent state, structured transcript, and native session identity; the generic adapter runs any CLI command with heuristic idle detection and a raw-terminal-only view. Adapters carry their own launch configuration (command, args, permission mode) with shipped defaults.
+
+### CLI Session
+A server-owned PTY bound to a task or chat entity. It survives client disconnects, supports concurrent attach from any surface, and carries an agent state (starting, ready, busy, waiting-on-input, done, dead). Its CLI-native session ID is persisted so a dead PTY or engine restart resumes via the CLI's own resume mechanism — needs-attention is the fallback when resume fails, never the first response.
+
+### Waiting-on-input
+The CLI Session state where the agent is blocked on the human (permission prompt, clarifying question), as distinct from idle-because-done. Entering it fires the notification configured on the workflow node; the task neither advances nor fails while in it.

 - "Merging" a shared-branch-group Task had been used for both member integration and group promotion — these are distinct steps with independent gating and must not be conflated.

+# CLI Executor — Requirements
+
+## Summary
+
+Add a new executor type — **cli-agent** — that runs Fusion agent sessions inside server-owned PTYs running interactive CLI coding agents (Claude Code, Codex, Droid, Pi). Fusion injects prompts, tracks agent state and session identity through each CLI's native telemetry, and drives the full task pipeline off it, while the user co-drives through a live interactive terminal on any surface. Chat gains a CLI-backed mode rendered as a structured transcript with a raw-terminal toggle.
+
+---
+
+## Problem Frame
+
+Fusion's primary persona is the developer juggling many Claude Code and Codex terminals across machines. Today Fusion can only drive agents through API-backed runtimes (model executors and agent executors over headless adapters like ACP). But the CLI agents are where these developers actually live: their subscriptions, authentication, configuration, skills, hooks, and muscle memory are attached to the CLI tools, not to raw API keys. There is currently no way to make a board task's execution *be* a Claude Code or Codex session — visible, steerable, and co-drivable — nor any way to chat through one.
+
+Orca (onorca.dev) demonstrates the model this feature should match: server-managed terminal sessions with per-CLI awareness — readiness detection, prompt injection, idle/busy tracking via installed agent hooks, native session-id capture, and resume across restarts — while the terminal stays fully interactive for the human.
+
+---
+
+## Key Decisions
+
+- **Native telemetry first, heuristics as fallback.** Each launch CLI gets an adapter that taps the CLI's own machinery — hooks and structured session logs — for precise state (busy / waiting-on-input / done), transcript content, and session identity. Any CLI without an adapter can still run through a generic PTY adapter using screen-quiet/idle heuristics, with a raw-terminal-only view. This mirrors Orca's hooks-based approach and keeps the adapter registry open, consistent with Fusion's neutrality thesis. Native-telemetry status for Codex, Droid, and Pi is contingent on a planning-time verification gate; only Claude Code is verified today.
+- **The executor identifier is `cli-agent`, not `cli`.** The engine already wires an `executorKind` of `cli` as a non-interactive runner for named project scripts and approval-gated raw commands (`packages/engine/src/executor.ts`) — opposite semantics to this feature. The interactive-PTY executor ships under the distinct `cli-agent` identifier, joining the existing executor kinds (model, agent, skill, and the script-runner `cli`).
+- **Full pipeline retained.** A CLI-executed task is a normal task: worktree and branch setup, completion detection driving the lifecycle, validator, in-review, and auto-merge all apply. The terminal is the execution surface; the board lifecycle is unchanged.
+- **Per-CLI launch configuration.** Each adapter carries its own configurable launch settings (command, args, permission/autonomy flags) with sensible shipped defaults, rather than a single global autonomy posture.
+- **Executor selection and attention behavior live on the workflow node for task surfaces; chat and CE sessions choose per session.** The workflow's execute node configures the CLI executor for task execution — the same node-level pattern covers planning and validator runs — including what happens when the agent blocks on input (notification), with per-task override. Chat and CE plugin sessions are not workflow nodes; they select their CLI executor in per-session settings.
+- **Orca-style session identity and resume.** The CLI's native session ID is captured per session and persisted; a dead PTY or engine restart relaunches the CLI with its native resume mechanism so agent context survives. Needs-attention is the fallback when resume fails, not the first response.
+- **Chat is a hybrid transcript.** A CLI-backed chat session renders structured messages parsed from the CLI's native telemetry, with a toggle to drop into the raw interactive terminal. No screen-scraping of TUI output into bubbles.
+- **Full surface parity.** The interactive terminal works on the desktop dashboard, mobile, and the TUI surface, all attached to the same server-owned session.
+
+---
+
+## Actors
+
+- A1. Developer — selects CLI executors, watches sessions, co-drives in the terminal, answers agent prompts.
+- A2. CLI agent — an external interactive process (Claude Code, Codex, Droid, Pi) running in a Fusion-owned PTY.
+- A3. Engine — spawns and owns CLI sessions, injects prompts, consumes telemetry, drives the task pipeline.
+- A4. Surfaces — desktop dashboard, mobile, and TUI clients that attach to live sessions for viewing and input.
+
+---
+
+## Key Flows
+
+- F1. CLI task execution
+  - **Trigger:** A task whose resolved executor is `cli-agent` starts its execute step.
+  - **Steps:** Engine prepares worktree/branch as usual; the adapter launches the configured CLI in a server-owned PTY in the worktree; waits for readiness; injects the task prompt; tracks busy state via telemetry; on done, the normal pipeline continues (validator, in-review, auto-merge).
+  - **Covers:** R1, R4, R5, R6, R10.
+- F2. Waiting on input
+  - **Trigger:** The CLI agent blocks mid-task (permission prompt, clarifying question).
+  - **Steps:** Telemetry (or heuristic) detects waiting-on-input; the task surfaces the state and fires the notification configured on the workflow node; the user opens the terminal on any surface, answers, and the agent resumes; state returns to busy.
+  - **Covers:** R6, R9, R11, R14.
+- F3. CLI-backed chat
+  - **Trigger:** User starts or switches a chat session to a CLI executor.
+  - **Steps:** Engine spawns (or resumes) the CLI session; chat messages are injected into the CLI; the conversation renders as a structured transcript from native telemetry; the user can toggle into the raw terminal at any time and type directly; transcript persists as chat history.
+  - **Covers:** R1, R15, R16.
+- F4. Session resume
+  - **Trigger:** Engine restart, PTY death, or a task/chat reopening an existing session.
+  - **Steps:** Engine looks up the persisted native session ID; relaunches the CLI with its resume mechanism in the same worktree; telemetry re-attaches; if resume fails, the task or chat surfaces needs-attention instead.
+  - **Covers:** R7, R8.
+- F5. Multi-surface attach
+  - **Trigger:** User opens a running session from another surface (e.g., phone).
+  - **Steps:** The surface attaches to the same server-owned PTY; output streams live; input from any attached surface reaches the session; detaching never kills the session.
+  - **Covers:** R4, R14.
+
+---
+
+## Requirements
+
+**Executor model**
+
+- R1. A task's execute step, planning session, validator run, Compound Engineering plugin session, and chat session can each specify executor type `cli-agent` with a chosen CLI adapter, alongside the existing executor kinds (model, agent, skill, and the non-interactive `cli` script runner, from which `cli-agent` is distinct).
+- R2. For task surfaces (execute, planning, validator), CLI executor selection and attention/notification behavior are configured on the workflow node, with per-task override. Chat and CE plugin sessions are not workflow nodes: they select their CLI executor in per-session settings.
+- R3. CLI support is an adapter registry. Claude Code ships as a verified native-telemetry adapter; Codex, Droid, and Pi are native-telemetry targets contingent on a planning-time verification gate (telemetry + resume), and any that fail verification launch on the generic tier instead. Any other CLI command can run through the generic PTY adapter (heuristic state detection, raw-terminal-only view).
+
+**Session management**
+
+- R4. CLI sessions are server-owned PTYs bound to their task or chat entity: they survive client disconnects and browser refreshes, and any number of surfaces can attach concurrently.
+- R5. The adapter detects CLI readiness before injecting a prompt, and defines the canonical safe injection format for its CLI; all injected text — task prompts and chat-composed messages alike — is escaped and delivered per that format (no premature or interleaved injection, no raw control-sequence passthrough).
+- R6. The engine tracks each session's agent state — starting, ready, busy, waiting-on-input, done/idle, dead — via the adapter's native telemetry, falling back to idle heuristics for generic adapters. A positive completion signal is distinct from mere idleness; adapters report which of the two they observed.
+- R7. The adapter captures the CLI's native session identity and persists it with the Fusion session record.
+- R8. After engine restart or PTY death, the engine resumes the session via the CLI's native resume mechanism in the same worktree; if resume fails, the owning task or chat surfaces needs-attention. Resume restores conversation context, not in-flight work: behavior for an action interrupted mid-flight (mid-tool-call or mid-edit at death) is explicitly defined, and worktree state is reconciled at resume rather than assumed clean.
+- R9. The user can type into the session at any time. Non-interference is a designed behavior, not an assumption: engine injection and human keystrokes are serialized on the shared PTY input stream (injection only occurs in detected ready/quiet windows, never mid-keystroke), and user input that changes the agent's state is reflected back into state tracking via telemetry.
+- R17. Attaching to a session from any surface requires the same authentication that governs other dashboard access; a session ID alone is never sufficient authorization, and sessions are accessible only to their owning authenticated user or workspace member.
+- R18. The engine enforces a configurable per-node limit on concurrent CLI sessions with a defined behavior at the ceiling (queue, or reject with a clear error) — never silent degradation.
+- R19. Stall backstop: a session showing no output progress beyond a configurable threshold without a detected done or waiting-on-input signal surfaces needs-attention, bounding the cost of a missed detection.

+  dead --> needsAttention: resume failed
+  done --> [*]
+```
+
+**Pipeline integration**
+
+- R10. A CLI-executed task follows the full task lifecycle: worktree/branch setup, completion detection advancing the task to the next stage, validator, in-review, and auto-merge behave as they do for model-executed tasks.
+- R11. When a session enters waiting-on-input, Fusion fires a notification according to the workflow node's configuration.
+- R12. A validator run on a CLI executor produces the same verdict contract (pass / fail / blocked / error) as a model-executed validator run.
+- R20. Advancement that leads toward merge (execute → validator → in-review/auto-merge) requires a positive completion signal from the adapter's native telemetry; idleness alone never advances a task. On the generic heuristic tier, idle-based completion requires explicit user confirmation before the task leaves the execute step; idle without a completion signal surfaces needs-attention instead of advancing.
+
+**Per-CLI configuration**
+
+- R13. Each adapter exposes launch configuration — command, arguments, permission/autonomy mode — with shipped defaults, editable in settings at the adapter level.
+- R21. Autonomy/permission launch flags above an adapter's shipped baseline are privileged settings (workspace-administrator editable), and a session's active autonomy posture is visibly surfaced wherever its terminal renders.
+- R22. Each adapter defines an explicit environment allowlist for its spawned CLI process; Fusion service credentials (API keys, tokens, database paths) are never forwarded into CLI-agent PTY environments.
+
+**Surfaces**
+
+- R14. The desktop dashboard task card, mobile, and the TUI surface each provide a live interactive terminal attached to the task's session.
+- R15. A CLI-backed chat session renders as a structured transcript with the standard chat composer injecting into the session, plus a toggle to a raw interactive terminal view.
+- R16. The structured transcript persists as the chat session's history, available after the session ends and across surfaces. Persistence reuses the existing chat-history storage layer (no parallel history store), and transcripts are sensitive data inheriting the originating session's access controls; retention specifics are a planning question.
+
+---
+
+## Acceptance Examples
+
+- AE1. **Covers R6, R10.** Given a CLI task whose agent finishes its work and goes idle with a completed result, when the adapter reports done, then the task advances out of the execute step into the normal validator/in-review flow without user action.
+- AE2. **Covers R6, R11.** Given a Claude Code task configured interactive, when the CLI shows a permission prompt, then the session state becomes waiting-on-input and the notification configured on the workflow node fires; the task does not advance and is not marked failed.
+- AE3. **Covers R7, R8.** Given an in-progress CLI task whose engine restarts, when the engine comes back up, then the session relaunches with the CLI's native resume and the agent retains its prior conversation context; the task remains in-progress.
+- AE4. **Covers R3.** Given a CLI with no native adapter launched via the generic adapter, when its session runs, then the user gets a raw interactive terminal and heuristic idle-based state, and no structured transcript is shown.
+- AE5. **Covers R9.** Given a busy CLI task session, when the user types guidance directly into the terminal mid-run, then the agent receives it, state tracking continues, and subsequent completion detection still advances the task normally.
+- AE6. **Covers R4, R14.** Given a CLI session started from the desktop, when the user opens the same task on mobile, then the same live terminal renders there and input from either surface reaches the one session.
+- AE7. **Covers R15, R16.** Given a CLI-backed chat session, when the user toggles between transcript and terminal views, then both reflect the same underlying session, and the transcript persists as chat history after the session ends.
+
+---
+
+## Scope Boundaries
+
+Deferred for later:
+
+- Agent-side completion protocol (instructing the agent to run a command when done) — a reliability layer on top of telemetry, not core.
+- CLI executors for arbitrary workflow script/prompt nodes — v1 surfaces are the execute step, planning, validator, CE plugin sessions, and chat.
+- Structured transcripts for generic-adapter CLIs (screen-output parsing) — generic tier is raw terminal only.
+- Multi-user collaborative co-driving semantics (presence, input arbitration) — v1 assumes the single-developer persona; concurrent attach is supported but unmediated.
+
+---
+
+## Dependencies / Assumptions
+
+- The chosen CLIs are installed and authenticated on the node where the engine runs; Fusion does not manage CLI installation or vendor auth in v1.
+- Each launch CLI offers usable native telemetry (hooks and/or structured session logs) and a session-resume mechanism. Verified for Claude Code (hooks, JSONL transcripts, `--resume`). Codex, Droid, and Pi verification is an explicit planning gate (per R3): each must demonstrate telemetry and resume before shipping at the native tier, with the generic tier as the defined fallback.
+- Existing engine PTY infrastructure (node-pty) and realtime transport (SSE/WebSocket) can carry interactive terminal streams to all three surfaces.
+- Mobile interactive terminal is feasible within the existing mobile web constraints (virtual keyboard handling is a known hard area).
+
+---
+
+## Outstanding Questions
+
+Deferred to planning:
+
+- Exact telemetry mechanism per CLI (hook events vs session-log tailing vs both) and what each CLI's resume supports.
+- Idle-heuristic thresholds and prompt-pattern sets for the generic adapter.
+- How planning and validator sessions map onto each CLI (interactive session vs the CLI's non-interactive/one-shot mode) while keeping the terminal visible.
+- Transcript persistence format and its relationship to existing chat history storage.
+- Concurrency/resource limits for simultaneous PTY sessions per node.
+
+---
+
+## Sources / Research
+
+- Orca behavior (inspected locally): per-CLI agent hook scripts (`~/.orca/agent-hooks/*.sh`) POST native CLI telemetry payloads — including the CLI's session ID — to a local endpoint keyed by pane/tab/worktree; terminals carry stable runtime handles; workspace session state (tabs, agent association) persists and restores across restarts; `orca terminal wait --for tui-idle` exposes idle detection as a primitive.
+- Existing executor/runtime seam: `packages/engine/src/runtime-resolution.ts`, `packages/engine/src/agent-runtime.ts`, `packages/engine/src/executor.ts`; headless CLI adapters already exist (`plugins/fusion-plugin-acp-runtime`, `packages/pi-claude-cli`, `packages/droid-cli`) — precedent for adapters, but none expose an interactive PTY.
+- PTY and transport infrastructure: `packages/dashboard/src/terminal-service.ts` (node-pty session manager, backend-only today), SSE buffers (`packages/dashboard/src/sse-buffer.ts`) and WebSocket manager (`packages/dashboard/src/websocket.ts`).
+- Workflow graph context: execute-node seam and node-level configuration per `docs/workflow-steps.md` (workflow IR, columns/traits, step instances) — the natural home for R2.

+
+## Deferred / Open Questions
+
+### From 2026-06-04 review
+
+- **Mobile interactive terminal fallback posture** — Surfaces / Dependencies (P1, design-lens, scope-guardian, confidence 100)
+
+  R14 commits full mobile interactive terminal while the dependencies section acknowledges mobile virtual-keyboard handling as a known hard area. No fallback posture is defined if full interactivity slips — e.g., a read-only terminal stream with a simplified input affordance and desktop handoff.
+
+  <!-- dedup-key: section="surfaces dependencies" title="mobile interactive terminal fallback posture" evidence="Mobile interactive terminal is feasible within the existing mobile web constraints (virtual keyboard handling is a known hard area)." -->
+
+- **Terminal embed placement on task card/detail view** — Surfaces (P1, design-lens, confidence 100)
+
+  The requirements give no product-level guidance on where the terminal lives in the existing task detail structure — a new tab, replacing the log viewer, or an overlay. Different implementers will independently invent the placement, producing inconsistent UX across surfaces.
+
+  <!-- dedup-key: section="surfaces" title="terminal embed placement on task carddetail view" evidence="R14. The desktop dashboard task card, mobile, and the TUI surface each provide a live interactive terminal attached to the task's session." -->
+
+- **Composer behavior in raw-terminal chat mode** — Surfaces (P1, design-lens, confidence 100)
+
+  R15 defines the transcript/terminal toggle but not what happens to the standard chat composer when raw-terminal mode is active. If the composer stays visible alongside a terminal that also accepts input, two competing input paths exist simultaneously.
+
+  <!-- dedup-key: section="surfaces" title="composer behavior in rawterminal chat mode" evidence="R15. A CLI-backed chat session renders as a structured transcript with the standard chat composer injecting into the session, plus a toggle to a raw interactive terminal view." -->
+
+- **Waiting/needs-attention surfacing vs existing stall badges** — Session management (P1, design-lens, confidence 100)
+
+  waiting-on-input and needs-attention are new task-card states with no defined visual relationship to the existing staleness, stuck, and stalled-review signals. Implementers will invent badges that may collide with the existing signal system.
+
+  <!-- dedup-key: section="session management" title="waitingneedsattention surfacing vs existing stall badges" evidence="R8. if resume fails, the owning task or chat surfaces needs-attention." -->
+
+- **Generic-adapter empty-state where transcripts render** — Requirements (P2, design-lens, confidence 75)
+
+  AE4 specifies generic-adapter sessions show no structured transcript, but not what users see where a transcript normally renders — hidden panel, explanatory message, or absent toggle. Each surface rendering transcripts must handle this fallback state consistently.
+
+  <!-- dedup-key: section="requirements" title="genericadapter emptystate where transcripts render" evidence="AE4. Given a CLI with no native adapter launched via the generic adapter, when its session runs, then the user gets a raw interactive terminal and heuristic idle-based state, and no structured transcript is shown." -->

+type: feat

+
+# feat: Add cli-agent executor with interactive PTY sessions
+
+## Summary
+
+Add a new executor kind, `cli-agent`, that runs Fusion agent sessions inside engine-owned PTYs running interactive CLI coding agents (Claude Code, Codex, Droid, Pi). The engine injects prompts, tracks agent state through per-CLI native telemetry adapters, captures native session IDs for resume, and drives the full task pipeline; users co-drive through live terminals on the dashboard, mobile, and TUI, and chat gains a hybrid transcript mode.
+
+---
+
+## Problem Frame
+
+Fusion drives agents only through API-backed runtimes today, but the primary persona lives in CLI coding agents — their subscriptions, auth, config, and skills are attached to the CLI tools. There is no way to make a board task's execution *be* a Claude Code or Codex session: visible, steerable, co-drivable, and resumable. Orca demonstrates the target model (hooks-based telemetry, session-id capture, resume); the origin doc pins the product behavior. This plan defines how it lands in the Fusion codebase.
+
+---
+
+## Requirements
+
+Carried from origin (see origin: docs/brainstorms/2026-06-04-cli-executor-requirements.md); the origin's R-IDs are authoritative and referenced by units below.
+
+**Executor model** — origin R1–R3: `cli-agent` selectable on the task execute step, planning, validator, CE plugin sessions, and chat; workflow-node configuration for task surfaces with per-task override, per-session for chat/CE; adapter registry with Claude Code verified native, Codex/Droid/Pi gated, generic PTY fallback.
+
+**Session management** — origin R4–R9, R17–R19: server-owned reattachable PTYs; safe readiness-gated injection; telemetry-driven state machine; native session-id capture and resume with worktree reconciliation; designed injection/keystroke serialization; attach auth; per-node concurrency limit; stall backstop.
+
+**Pipeline integration** — origin R10–R12, R20: full task lifecycle; waiting-on-input notifications per workflow-node config; validator verdict contract preserved; positive-completion-signal gating before merge-bearing advancement.
+
+**Per-CLI configuration** — origin R13, R21–R22: adapter-level launch config with shipped defaults; privileged autonomy flags with visible posture; per-adapter env allowlist.
+
+**Surfaces** — origin R14–R16: interactive terminal on dashboard, mobile, TUI; chat hybrid transcript with raw-terminal toggle; transcript persistence reusing chat history storage.
+
+The CLI verification gate origin R3 requires has been run (see Sources): all four CLIs pass for the native tier — Codex with a hybrid caveat (no native waiting-on-input signal), Droid with message-parsing on its `Notification` hook.
+
+---
+
+## Key Technical Decisions
+
+- **Engine-owned `CliAgentAdapter` abstraction, not an `AgentRuntime` plugin.** The existing runtime contract (`packages/engine/src/agent-runtime.ts`: `createSession`/`promptWithFallback`/`describeModel`) is API-shaped and cannot model a PTY stream, two-way co-driving, or resume. A new adapter interface (spawn command/args, telemetry wiring, state classification, resume invocation, injection formatting) lives in the engine; the four launch adapters ship as engine code. A plugin contribution point for third-party adapters is deferred to follow-up — this avoids the 5-list bundled-plugin registration burden (see `docs/solutions/integration-issues/bundled-plugin-registration-drift.md`) while keeping the registry shape open.
+- **Executor identifier is `cli-agent`.** `executorKind === "cli"` already exists in `packages/engine/src/executor.ts` (`runGraphCustomNode`) as the non-interactive script runner. The new kind branches alongside `model`/`agent`/`skill`/`cli` and routes to the PTY session path — never into `executeWorkflowStep`.
+- **Resume-the-CLI architecture; SIGKILL registry is the authoritative teardown.** PTYs cannot survive engine process death (no detached broker in v1). Recovery is relaunching the CLI with its native resume mechanism (`claude --resume`, `codex resume`, `droid exec -s`, `pi --session`) in the same worktree. Teardown follows the ACP precedent: process registry with scoped SIGKILL on engine exit, graceful close opportunistic, never targeting port 4040.
+- **Termination taxonomy and resume-eligibility predicate.** Every PTY end is classified — `completed` (positive done signal), `userExited` (clean child exit mid-task), `killed` (hard cancel / column exit), `crashed` (signal/nonzero exit), `authFailed` (credential pattern), `engineDeath` (found dead on restart). Only `engineDeath` and `crashed` are resume-eligible, capped at 2 attempts with backoff; `killed` and `userExited` never auto-resume; `authFailed` goes straight to needs-attention with a re-authenticate message. The classification persists on the session record so self-healing sweeps cannot resurrect a cancelled session.
+- **Telemetry tiering with per-adapter capability flags.** Adapters declare which states they detect natively. Claude Code: full hooks (`Stop`, `Notification`, `PermissionRequest`, `session_id` in every payload). Codex: native turn-complete via `notify` config only — waiting-on-input falls back to PTY prompt-pattern detection (hybrid tier). Droid: Claude-style hooks, but `Notification` conflates permission/idle and requires message parsing. Pi: event stream / session JSONL. Generic adapter: output-quiet heuristics, raw-terminal-only. Hook scripts POST to a **dashboard-served localhost endpoint that forwards to the engine telemetry hub** (the engine has no HTTP server — only the dashboard serves HTTP; the Orca pattern, adapted). The engine mints a high-entropy per-session hook token at spawn; the dashboard route validates it against the engine-held registry and rejects Origin/Host headers from browser contexts — localhost is not a trust boundary, and a forged completion event would otherwise drive pipeline advancement (see Risks).
+- **PTY ownership: node-pty becomes an engine dependency, with the native-asset machinery extracted to a shared utility living in the engine.** The PTY-fragility apparatus in `packages/dashboard/src/terminal-service.ts` (prebuild path resolution, dlopen fallback, permission repair for packaged binaries) is extracted into a shared module **in `@fusion/engine`** consumed by both the engine's `CliSessionManager` and the dashboard terminal service (the dashboard already depends statically on `@fusion/engine`; `@fusion/core` never takes node-pty — a native dep in core would transitively reach every core consumer). Binary-release validation of engine-side PTY spawn is an explicit acceptance item (U16), not deferred polish. Alternative rejected: dashboard-injected PTY service — it would invert the ownership the whole design rests on (engine owns sessions).
+- **The engine `CliSessionManager` exposes an explicit async interface, not EventEmitter callbacks.** Attach returns scrollback + an async byte stream; write/resize/requestPause/requestResume are methods. The engine is the sole owner of the scrollback ring buffer and of watermark-driven PTY pause/resume; the dashboard WS layer forwards ACK credit and never buffers bytes itself. This keeps the engine↔dashboard seam process-split-credible (today's terminal-service EventEmitter shape would not survive a split).
+- **Positive completion signal gates pipeline advancement (origin R20).** Idle never advances a task. Native adapters advance on their done event; the generic tier surfaces an idle-based "looks done — confirm to advance" affordance; idle without signal beyond the stall threshold → needs-attention. waiting-on-input suppresses the existing stuck-task detector (expected idleness).
+- **Separate per-node PTY concurrency pool.** CLI sessions hold slots for human-paced durations; they get their own configurable ceiling (default modest, reject-with-error at ceiling) instead of consuming `AgentSemaphore` execute slots, so a watched terminal never starves model-executor throughput. Resume-on-restart respects the same ceiling (queue beyond it).
+- **Transport: WebSocket for terminal bytes, SSE for state.** Terminal I/O extends the existing `/api/terminal/ws` upgrade path (JSON-framed scrollback/data messages, daemon-token authenticated at upgrade, project-scoped) with CLI-session attach; agent-state transitions (`cli:session:state`) ride the existing SSE event bus so cards/banners update without touching the byte stream. Attach auth rides the existing single daemon-token model + project scoping — a per-user/workspace-member model does not exist in the codebase and is explicitly deferred; origin R17's intent (session ID alone is never authorization) is satisfied by token-gated upgrade.
+- **Privileged autonomy flags map to the approval-gate precedent, not a new role system.** Launch configs above an adapter's shipped baseline (e.g. `--dangerously-skip-permissions`, `codex --full-auto`) require an explicit stored approval per project — same shape as `isWorkflowCliCommandApproved` for raw workflow commands — and the active posture renders as a visible chip wherever the terminal renders (origin R21). A real admin role is out of scope.
+- **Validator and planning run the CLI's non-interactive one-shot mode with a read-only terminal.** One-shot invocations (`claude -p`, `codex exec --json`, `droid exec`, pi headless) yield deterministic output for the pass/fail/blocked/error verdict contract (origin R12) while the PTY output still streams to a read-only terminal view for observability. Interactive co-driving is execute-step and chat only.
+- **Chat transcripts reuse `chat_sessions`/`chat_messages`.** The structured transcript is parsed from native telemetry (transcript JSONL tail / event stream) into `chat_messages` rows; the native session id persists on the session record (the `chat_sessions.cliSessionFile` column is existing precedent). Injection from the composer and raw keystrokes share one FIFO per session; the composer shows a queued state while the agent is busy.
+- **UI placements (resolves the origin's deferred design questions).** Task detail: a new `terminal` tab in `TaskDetailModal`'s `TabId` union (Logs tab unchanged). Chat: raw-terminal mode replaces the message list and hides the composer (the terminal owns input; a toggle returns to transcript view). waiting-on-input / needs-attention surface as a task-card badge plus the existing `SessionNotificationBanner` — distinct from staleness/stall badges, which are suppressed while waiting. Generic-adapter sessions render terminal-only (no transcript pane, no toggle). Mobile ships the interactive terminal with a visible input field + accessory key bar (Esc/Tab/Ctrl/arrows) — xterm's hidden-textarea input is unreliable on mobile; if interactivity slips during implementation, the defined fallback is read-only stream + input field.
+- **Client terminal stack: `@xterm/xterm` 6.x** with fit, webgl (with context-loss fallback to DOM renderer), unicode11 addons; custom WS bridge (not `addon-attach` — no flow control); server-side byte ring buffer replay on attach; resize policy: latest-active-client wins (single-developer multi-surface), debounced. ACK-based backpressure (pause/resume PTY on watermarks).
+- **No web-push in v1.** Origin R11's notification fires through the existing in-app surfaces (SSE-driven banner/badge + OS-level notification where the desktop shell supports it); workflow-node config selects banner-only vs. banner+notify. Push infra is a deferred follow-up.

+## Implementation Units
+
+Phased: A (engine core) → B (pipeline) → C (transport & surfaces) → D (config & polish). Units are dependency-ordered within phases; Phase A order is U16 → U1 → U2 → U3 → U17 → U4 → U5 → U6.
+
+### U16. Shared PTY native-asset utility and redactSecrets extraction
+
+**Goal:** Extract the node-pty loading/permission-repair machinery into an engine-owned shared module consumed by engine and dashboard; extract `redactSecrets` into core; validate engine-side PTY spawn in packaged binaries.
+**Requirements:** prerequisite for origin R4 (engine-owned PTYs) and the R16 transcript-redaction mitigation.
+**Dependencies:** none. (U16 and U1 are independent and parallelizable; the stated Phase A order is a suggested sequence, not a dependency chain.)
+**Files:** `packages/engine/src/pty-native.ts` (new — extracted from `packages/dashboard/src/terminal-service.ts` lines ~21–178), `packages/dashboard/src/terminal-service.ts` (consume the shared module via its existing static `@fusion/engine` dependency), `packages/engine/package.json` (node-pty dependency), `packages/core/src/redact-secrets.ts` (new — extracted from `plugins/fusion-plugin-acp-runtime/src/process-manager.ts`, with the plugin re-importing it), `packages/engine/src/__tests__/pty-native.test.ts`, `packages/core/src/__tests__/redact-secrets.test.ts`.
+**Approach:** Move the lazy-load, prebuild path resolution, dlopen fallback, and native-permission repair into one engine utility; the dashboard terminal service keeps identical behavior; node-pty is declared in the engine (never in core — a native dep there would reach every core consumer). `redactSecrets` moves to `@fusion/core` (pure string logic, no native deps) so U12's transcript persistence can import it; the ACP plugin re-imports the shared function. Binary-release validation (Bun-compiled binary spawns a PTY from engine code) is part of this unit's acceptance, exercised via the release-branch `workflow_dispatch` path noted in the release-pipeline learnings.
+**Patterns to follow:** existing terminal-service loader; release-pipeline gotchas (never cache node_modules on Windows, native asset staging).
+**Test scenarios:**
+- Loader resolves node-pty in dev (workspace) mode and packaged-binary mode (fixture paths).
+- Dashboard terminal service behavior unchanged (existing terminal tests stay green).
+- Permission-repair path exercised on a fixture with broken modes.
+- `redactSecrets` parity: shared function produces identical output to the plugin's previous local copy on its existing fixtures; the ACP plugin's tests stay green against the re-import.
+**Verification:** existing dashboard terminal tests green against the shared module; packaged-binary PTY smoke recorded as a release-validation checklist item.
+
+### U1. cli_sessions persistence and session records
+
+**Goal:** Durable session records carrying identity, state, termination classification, and resume bookkeeping.
+**Requirements:** origin R4, R6, R7, R8.
+**Dependencies:** none.
+**Files:** `packages/core/src/db.ts` (schema v109), `packages/core/src/cli-session-store.ts` (new), `packages/core/src/cli-session-types.ts` (new), `packages/core/src/__tests__/cli-session-store.test.ts`, `packages/core/src/__tests__/db-migrate.test.ts` (extend).
+**Approach:** New `cli_sessions` table following the `ai_sessions`/`chat_sessions` patterns: TEXT PK, owning entity (taskId | chatSessionId | purpose), projectId, adapterId, agent state, termination reason, native session id, resume attempt count, autonomy posture, worktree path, timestamps. Store class follows `ChatStore` (EventEmitter + SQLite). Migration as an `applyMigration(109, ...)` block.
+**Patterns to follow:** `chat_sessions` table + `ChatStore`; `addColumnIfMissing`/`CREATE TABLE IF NOT EXISTS` migration idiom; DB-corruption-resilience posture (integrity-checked, recoverable).
+**Test scenarios:**
+- Happy path: create/read/update a session record; state transitions persist; native session id round-trips.
+- Migration: v108 → v109 migrates cleanly on an existing DB fixture; fresh DB creates the table.
+- Edge: termination reason and resume attempt count update atomically with state; querying sessions by task and by chat entity.
+- Error: invalid state value rejected at the store boundary.
+**Verification:** store tests green; migration test proves both upgrade and fresh-create paths.
+
+### U2. CliSessionManager and CliAgentAdapter interface
+
+**Goal:** Engine-owned PTY lifecycle: spawn, ring-buffer scrollback, injection FIFO, resize, process registry teardown, concurrency pool.
+**Requirements:** origin R4, R5, R9, R18, R22.
+**Dependencies:** U1, U16.
+**Files:** `packages/engine/src/cli-agent/adapter.ts` (new — interface + registry), `packages/engine/src/cli-agent/session-manager.ts` (new), `packages/engine/src/cli-agent/__tests__/session-manager.test.ts`, `packages/engine/src/cli-agent/__tests__/adapter-registry.test.ts`.
+**Approach:** Adapter interface declares: launch command/args builder (from settings + autonomy posture), env allowlist, capability flags (native done / native waiting / transcript source / resume), readiness detection, injection formatter, resume command builder, telemetry wiring. Injection formatting: bracketed paste only when `?2004h` observed (interleaving safety), and control characters (`\r` beyond intended submits, `\x03`, `\x04`, ESC-prefixed sequences) are stripped/escaped **unconditionally** on the raw fallback path — control-char neutralization is the security control and must hold when paste mode is off. Session manager owns node-pty processes via the U16 shared loader, is the **sole owner** of the byte-bounded scrollback ring and watermark-driven PTY pause/resume (exposing `requestPause`/`requestResume` for transport-layer ACK credit), a single serialized write queue (engine injections + user input share it; injections wait for ready/quiet windows), resize with latest-active-client policy, and a process registry with `process.on("exit")` scoped SIGKILL (never port 4040). Attach surface is an explicit async interface (scrollback fetch + async byte stream + write/resize methods), not EventEmitter callbacks. Separate PTY concurrency pool with configurable ceiling, reject-with-error at ceiling.
+**Patterns to follow:** `plugins/fusion-plugin-acp-runtime/src/process-manager.ts` (env allowlist, scoped SIGKILL, self-cleaning registry); `terminal-service.ts` scrollback/throttle machinery; `superviseSpawn` policy from AGENTS.md (route PTY spawn through the sanctioned path or explicit allowlist).
+**Test scenarios:**
+- Happy path: spawn a fake CLI (scripted PTY child), readiness detected, prompt injected once ready, output lands in ring buffer, clean teardown kills the child.
+- Injection serialization: user write queued mid-injection never interleaves bytes; two queued injections deliver in FIFO order; injection deferred while output is streaming.
+- Bracketed paste: wrapped only when the child enabled `?2004h`; raw otherwise.
+- Control-char neutralization: injected message containing `\x03`, `\x04`, and an ESC sequence is neutralized on the raw (non-paste) path — never reaches the PTY as control input.
+- Concurrency: (ceiling = 2) third session rejected with a clear error; slot released on teardown.
+- Env: child env contains only the allowlist — assert `FUSION_*` tokens and service credentials absent.
+- Teardown: process-registry kill on simulated engine exit leaves no orphans (two-turns-through-one-session test for latched state).
+**Verification:** all session-manager tests green with a scripted PTY fixture; no orphan processes after suite run.
+
+### U3. Telemetry hub and session state machine
+
+**Goal:** Authoritative agent-state machine with completion gating, stall backstop, and termination classification — pure engine code, fixture-driven, no HTTP.
+**Requirements:** origin R6, R19, R20; flows F1, F2.
+**Dependencies:** U1, U2.
+**Files:** `packages/engine/src/cli-agent/telemetry-hub.ts` (new — ingestion contract + per-session token registry), `packages/engine/src/cli-agent/state-machine.ts` (new), `packages/engine/src/cli-agent/__tests__/state-machine.test.ts`, `packages/engine/src/cli-agent/__tests__/telemetry-hub.test.ts`.
+**Approach:** The hub exposes an in-process ingestion contract consumed by the U17 route and by adapters that tail logs (Codex rollout, Pi JSONL). It mints high-entropy per-session hook tokens at spawn (registry keyed by session id, invalidated on session end; on engine restart the registry is rebuilt only from sessions still live in `cli_sessions`, so stale on-disk tokens never validate) that U17 validates. State machine implements the HTD diagram including the dead-classification choice and resume-attempt caps; emits `cli:session:state` SSE events (throttled) and persists transitions via U1. Positive-completion distinct from idle; stall backstop (no output progress past configurable threshold without done/waiting) → needsAttention. Inactivity watchdog re-armed by telemetry/output events — no fixed turn timeout. Bound and sanitize everything ingested: per-chunk and per-turn caps, ANSI/control stripping before pattern matching, redaction across chunk boundaries.
+**Patterns to follow:** `docs/solutions/architecture-patterns/observable-long-running-agent-turns-through-blocking-plugin-route-seam.md` (push channel additive, deltas not snapshots, never-reject detached turns, inactivity watchdog, throttled SSE); ACP event-bridge bounding rules.
+**Test scenarios:**
+- Covers AE1. Native done signal advances state to done; idle alone never does.
+- Covers AE2. Permission-prompt signal → waitingOnInput; notification dispatch invoked per node config; state does not advance or fail.
+- Stall backstop: quiet session with no signals past threshold → needsAttention; busy session streaming output never trips it.
+- Termination classification: clean exit-0 mid-task → userExited; SIGKILL from hard cancel → killed (no resume); nonzero exit → crashed (resume-eligible); credential-failure pattern in output → authFailed.
+- Resume caps: two failed resumes → needsAttention, third never attempted.
+- Token registry: token validates only for its own session; invalidated after session end; a forged completion for session A using session B's token is rejected.
+- Two-turns-through-one-handler: per-turn latches/budgets reset between turns.
+**Verification:** state-machine tests cover every edge in the HTD diagram, with no HTTP involved.
+
+### U17. Hook ingestion route and token lifecycle
+
+**Goal:** Dashboard-served localhost endpoint that authenticates hook POSTs and forwards them to the engine telemetry hub.
+**Requirements:** origin R6 (telemetry delivery), R17 principle applied to the hook channel.
+**Dependencies:** U3.
+**Files:** `packages/dashboard/src/routes/cli-agent-hooks.ts` (new), Fusion-provided hook scripts/notify shim under `packages/engine/src/cli-agent/hook-scripts/` (new), `packages/dashboard/src/routes/__tests__/cli-agent-hooks-route.test.ts`.
+**Approach:** Route validates the per-session token against the U3 engine-held registry (session id alone never sufficient), rejects browser-context requests (Origin/Host header check — localhost is not a trust boundary; a page must not be able to CSRF the endpoint), caps payload size, and forwards validated payloads in-process to the hub. Hook scripts (Orca `~/.orca/agent-hooks/*.sh` shape) carry the token via session-scoped env/config; **the session-scoped hook config directory is deleted on session end**, and tokens are registry-invalidated at the same moment, so the at-rest exposure is bounded to the session's lifetime.
+**Test scenarios:**
+- Valid token + session → forwarded to hub; state visible downstream.
+- Missing/wrong/expired token → 401; valid-format token for the wrong session → rejected.
+- Request with a browser `Origin` header → rejected; oversized payload → capped/rejected.
+- Unknown session key is a no-op, not a crash.
+- Lifecycle: session end deletes the hook config dir and invalidates the token; a replayed POST with the old token is rejected; after engine restart, tokens for non-live sessions are rejected.
+**Verification:** route tests prove auth, CSRF rejection, lifecycle cleanup, and bounding against a stub hub.
+
+### U4. Claude Code adapter (native tier)
+
+**Goal:** Reference native adapter: hooks installed per session, JSONL transcript tail, session-id capture, resume.
+**Requirements:** origin R3, R5–R8; AE3.
+**Dependencies:** U2, U3.
+**Files:** `packages/engine/src/cli-agent/adapters/claude-code.ts` (new), `packages/engine/src/cli-agent/adapters/__tests__/claude-code.test.ts`.
+**Approach:** Launch with per-session hook config (settings-dir scoped to the session, never mutating the user's global `~/.claude` hooks — additive project/local hook config) wiring `Stop`, `Notification`, `PermissionRequest`, `SessionStart` to the U17 endpoint with the U3-minted session token; capture `session_id` from the first payload; transcript content from the JSONL at `transcript_path` for chat transcripts; resume via `--resume <session-id>` (confirm `SessionStart.source === "resume"`); waiting-on-input from `PermissionRequest`/`Notification` types. Verify actual hook roster against the installed version at scaffold time (smoke test), per the SDK-authoritative learning.
+**Patterns to follow:** ACP `cli-spawn.ts` settings resolution; the plugin-skills learning's `assertPluginLocalTarget` posture (never write to global agent config dirs).
+**Test scenarios:**
+- Happy path: simulated hook payload sequence (SessionStart → PreToolUse → Stop) drives ready→busy→done; session_id persisted on first payload.
+- Covers AE3. Kill PTY, resume builder produces `--resume <id>`, simulated `SessionStart{source:resume}` re-attaches telemetry; state returns to busy.
+- Waiting: `PermissionRequest` payload → waitingOnInput; `Notification{idle_prompt}` → waitingOnInput.
+- Edge: hook payload missing optional fields tolerated; hooks config written only to session-scoped location.
+**Verification:** adapter tests green against recorded payload fixtures; a manual smoke run against a real `claude` binary is an explicit implementation-time checklist item (not CI).
+
+### U5. Codex, Droid, and Pi adapters
+
+**Goal:** Remaining launch adapters at their verified tiers.
+**Requirements:** origin R3, R5–R8.
+**Dependencies:** U2, U3, U4 (patterns).
+**Files:** `packages/engine/src/cli-agent/adapters/codex.ts`, `packages/engine/src/cli-agent/adapters/droid.ts`, `packages/engine/src/cli-agent/adapters/pi.ts` (new), with sibling `__tests__/` files per adapter.
+**Approach:** Codex (hybrid tier): `notify` config invokes a Fusion-provided program POSTing `agent-turn-complete` (carries `thread-id` as session id); waiting-on-input via PTY prompt-pattern detection (ANSI-stripped, spinner-aware); resume via `codex resume <thread-id>`; rollout JSONL path treated as version-sensitive (probe, don't hardcode). Droid: Claude-style hooks; parse `Notification.message` to split permission vs idle (documented gap); resume interactive `--resume <id>` / headless `exec -s <id>` (never `-r` in exec mode). Pi: `--mode json` event stream or session-JSONL tail; session file/id via session dir; resume `--session <id>`. Each adapter declares honest capability flags so the UI can render tier differences.
+**Test scenarios (per adapter):**
+- Done signal: simulated native event → done.
+- Waiting: Codex prompt-pattern fixture (ANSI noise included) → waitingOnInput; Droid permission-vs-idle message fixtures classified correctly; Pi `input` event → waitingOnInput.
+- Resume: builder produces the correct CLI invocation per mode; Droid exec-mode `-r` footgun explicitly asserted absent.
+- Session-id capture from each CLI's native source.
+- Covers AE4 (boundary): an adapter with native flags disabled behaves identically to the generic tier.
+**Verification:** fixture-driven tests per adapter; per-CLI manual smoke runs are implementation-time checklist items.
+
+### U6. Generic PTY adapter (heuristic tier)
+
+**Goal:** Any CLI command runs with output-quiet idle heuristics and raw-terminal-only presentation.
+**Requirements:** origin R3, R6, R20; AE4.
+**Dependencies:** U2, U3.
+**Files:** `packages/engine/src/cli-agent/adapters/generic.ts` (new), `packages/engine/src/cli-agent/adapters/__tests__/generic.test.ts`.
+**Approach:** ANSI-stripped last-screen analysis: prompt-glyph + spinner-override busy detection, configurable quiet-window idle; no native done — idle yields a "confirm to advance" affordance per the R20 decision; no transcript source (capability flags all false). No resume (fresh launch only) — surfaced honestly in UI.
+**Test scenarios:**
+- Covers AE4. Generic session exposes raw terminal only; no transcript; heuristic idle state reported as idle, never as done.
+- Spinner override: prompt visible + spinner animating → busy.
+- Quiet window: output silence past threshold → idle; resumed output flips back to busy.
+**Verification:** heuristic fixtures (recorded PTY byte streams) classify correctly.
+
+### U7. Executor seam wiring and task lifecycle integration
+
+**Goal:** `cli-agent` selectable on workflow nodes; execute step runs through a CLI session honoring cancel/abort/re-entry semantics and pipeline advancement.
+**Requirements:** origin R1, R2, R10, R20; F1; AE1, AE5.
+**Dependencies:** U1–U4.
+**Files:** `packages/engine/src/executor.ts` (seam branch in `runGraphCustomNode` + execute/stepExecute seams), `packages/engine/src/cli-agent/task-session.ts` (new — task↔session orchestration), `packages/core/src/workflow-ir-types.ts` (node config additions), `packages/engine/src/__tests__/cli-agent-executor.test.ts`, `packages/engine/src/cli-agent/__tests__/task-session.test.ts`.
+**Approach:** Node config gains `executor: "cli-agent"`, adapter id, autonomy posture ref, and attention/notification settings (origin R2, R11); per-task override follows existing per-task settings precedent. Live sessions snapshot their resolved executor at launch — node-config edits apply to the next run only. Hard cancel (`moveTask(in-progress→todo)`) and column-exit abort SIGKILL the PTY tree, mark `killed`, release the pool slot, and never resume. Done (per R20 gating) advances the normal pipeline; PTY is reaped at the execute→in-review handoff (autoMerge:false tasks don't hold slots). Re-plan/RETHINK re-entry launches fresh (context reset); follow-up to a done-but-reaped session resumes first, then injects.
+**Patterns to follow:** existing `agent`/`skill`/`cli` kind branches in `runGraphCustomNode`; `active-session-registry` worktree-keyed ownership; `moveTask` hard-cancel contract (AGENTS.md).
+**Test scenarios:**
+- Covers AE1 / F1. Execute step with cli-agent node: worktree session spawns, prompt injected, simulated done advances task to validator/in-review; PTY reaped at handoff.
+- Covers AE5. Simulated user input mid-busy: state tracking continues; subsequent done still advances.
+- Hard cancel: moveTask in-progress→todo kills PTY, session `killed`, no resume on next self-healing sweep, slot released.
+- Re-entry: needs-replan re-entering execute starts a fresh session; follow-up on done task resumes the recorded session id.
+- Node-config edit mid-run: live session keeps launch-time executor; next run uses the new config.
+- Ceiling: execute step at PTY-pool ceiling surfaces a clear queued/rejected state, task does not silently stall.
+**Verification:** engine integration tests with scripted adapters prove the full lifecycle without real CLIs.
+
+### U8. Resume, restart recovery, and self-healing integration
+
+**Goal:** Engine restart finds dead sessions and resumes per the eligibility predicate; failures surface as needs-attention; existing sweeps respect CLI semantics.
+**Requirements:** origin R7, R8, R19; F4; AE3.
+**Dependencies:** U1–U4, U7.
+**Files:** `packages/engine/src/cli-agent/resume-coordinator.ts` (new), `packages/engine/src/self-healing.ts` (CLI-session awareness), `packages/engine/src/stuck-task-detector.ts` (suppress while waitingOnInput), `packages/engine/src/cli-agent/__tests__/resume-coordinator.test.ts`, `packages/engine/src/__tests__/self-healing-cli-sessions.test.ts`.
+**Approach:** On engine start, sessions persisted as live are classified `engineDeath` and queued for resume (respecting the pool ceiling); resume relaunches via the adapter's resume builder in the recorded worktree, reconciles worktree state (dirty-tree detection logged, surfaced on the session), re-attaches telemetry, and re-injects nothing (replay-suppression: scrollback replays to viewers, but no prompt re-injection). **Worktree-existence precondition:** the resume coordinator verifies the recorded worktree still exists before relaunch — a missing worktree routes to needsAttention, never a CLI spawned into a vanished directory; conversely, self-healing's idle-worktree sweeps (`enforceWorktreeCap`, `scanIdleWorktrees`) must treat a worktree backing a resume-eligible `cli_sessions` record as in-use, so a reaped-but-resumable session (e.g. done task awaiting a follow-up) cannot have its worktree reclaimed out from under it. Eligibility predicate per the termination-taxonomy KTD; attempt cap 2 with backoff; exhaustion or missing vendor session store → needsAttention. waitingOnInput suppresses stuck/inactivity detection; R19's stall backstop is the only escalation path while waiting.
+**Test scenarios:**
+- Covers AE3 / F4. Simulated engine restart with a live session record: resume invoked with the recorded native id; state returns busy; task stays in-progress.
+- Eligibility: `killed` and `userExited` records are never resumed by sweeps; `authFailed` goes to needs-attention without a resume attempt.
+- Cap: two consecutive resume failures → needsAttention; no third spawn across multiple sweep cycles.
+- Missing vendor store: resume command fails immediately → permanent-failure path, not retry loop.
+- Suppression: waitingOnInput session not flagged by stuck-task detector; same session trips the stall backstop only when genuinely quiet.
+- Dirty worktree at resume: flagged on the session record, resume proceeds, flag visible to UI.
+- Missing worktree at resume: routes to needsAttention without spawning; idle-worktree sweep skips a worktree backing a resume-eligible session record.
+**Verification:** restart-shaped integration test (new engine instance over the same DB fixture) proves recovery without duplicate sessions.
+
+### U9. Validator, planning, and CE plugin session support
+
+**Goal:** The remaining v1 surfaces run on CLI executors in one-shot mode with read-only terminals.
+**Requirements:** origin R1, R12.
+**Dependencies:** U2–U5, U7, U10 (read-only terminal attach).
+**Files:** `packages/engine/src/cli-agent/one-shot-session.ts` (new), validator/planning resolution touchpoints in `packages/engine/src/executor.ts` and `packages/engine/src/interactive-ai-session.ts`, CE plugin seam in `plugins/fusion-plugin-compound-engineering` (session factory option), `packages/engine/src/cli-agent/__tests__/one-shot-session.test.ts`, `packages/engine/src/__tests__/cli-agent-validator.test.ts`.
+**Approach:** One-shot mode invokes the adapter's non-interactive form (`claude -p`, `codex exec --json`, `droid exec --output-format json`, pi headless), streams output to a read-only terminal view (same WS channel and attach-ticket route as interactive sessions, with input disabled **server-side**, not just in the client), and parses the structured result. Validator maps the parsed result into the existing pass/fail/blocked/error verdict contract — a malformed/unparseable result is `error`, never a silent pass. Planning sessions persist their output through the existing planning flow. CE plugin sessions thread the executor choice through the session-factory option seam (per the plugin-skills learning: thread options end-to-end, prove with a real loader).
+**Test scenarios:**
+- Validator verdict mapping: fixtures for pass/fail/blocked outputs per adapter shape; malformed output → error verdict (never pass).
+- One-shot lifecycle: session record created, read-only flag set, terminal stream available, reaped on completion.
+- Planning: one-shot output lands in the planning flow as a model-backed run would.
+- Error path: one-shot CLI nonzero exit → verdict error with stderr (bounded) on the record.
+**Verification:** validator integration test proves the verdict contract is indistinguishable from model-executed runs downstream.
+
+### U10. Transport: WS attach, SSE state events, injection API
+
+**Goal:** Surfaces attach to live sessions (authenticated), receive scrollback + live bytes, send input; state events stream over SSE; chat composer injects via API.
+**Requirements:** origin R4, R9, R14, R17; F5; AE6.
+**Dependencies:** U2, U3.
+**Files:** `packages/dashboard/src/server.ts` (WS upgrade routing for cli-agent sessions), `packages/dashboard/src/routes/cli-sessions.ts` (new — list/attach-ticket/inject/confirm-advance routes), `packages/dashboard/src/sse.ts` (new `cli:session:state` event), `packages/dashboard/src/__tests__/cli-sessions-routes.test.ts`, `packages/dashboard/src/__tests__/cli-session-ws.test.ts`.
+**Approach:** cli-agent attach is a **distinct connection handler** keyed off session kind, sharing only the upgrade gate with the existing terminal WS — the connection body resolves sessions from the engine's `CliSessionManager` (via U2's explicit async interface), not the dashboard-local terminal service. Attach auth: the daemon-token upgrade gate plus a **short-lived, single-use, session-scoped attach ticket** minted by an authenticated route (the long-lived daemon token never authorizes PTY write access by itself), and an **Origin allowlist check** on the upgrade — the existing terminal WS's weaker posture is insufficient for a channel carrying keystroke injection into privileged agent PTYs. Scrollback replay on connect, JSON-framed data/resize/input messages; flow control forwards ACK credit to U2's `requestPause`/`requestResume` (the dashboard never buffers bytes). Outbound hardening: the terminal byte stream is untrusted (see Risks) — the server-side bridge neutralizes clipboard-write (`OSC 52`), constrains `OSC 8` hyperlink schemes, and strips device-query sequences whose auto-responses would forge input. Input frames and engine injections converge on U2's FIFO, and each input frame's source (attach-ticket identity) is logged on the session record for post-incident attribution — v1 has no per-user arbitration, so attribution is the accountability floor. SSE event carries state transitions + bounded last-output preview; clients merge (never wholesale-replace enriched fields — the stale-`isGenerating` learning). Inject route powers the chat composer and any non-WS surface; confirm-advance route powers the generic-tier R20 affordance (UI pinned in U11: a persistent action strip below the terminal viewport — "This session looks idle — advance to review?" with Advance / Not yet; dismissing stays in execute and re-arms the idle timer).
+**Patterns to follow:** existing terminal WS handler (`server.ts` upgrade + scrollback frames); `sse-buffer.ts` ring replay; queued-chat-message learning (re-fetch authoritative state before side-effecting actions).
+**Test scenarios:**
+- Covers AE6 / F5. Two concurrent attaches to one session both receive live bytes; input from either reaches the PTY; detach of one never kills the session.
+- Auth: attach without daemon token rejected at upgrade; cross-project session id rejected by scope check; foreign/absent `Origin` rejected; replayed attach ticket rejected; ticket for session A cannot attach session B.
+- Output hardening: recorded byte stream containing `OSC 52`, an `OSC 8` `javascript:` link, and a device-status query is neutralized — clipboard untouched, link scheme rejected, no synthetic input frame emitted.
+- Replay: late attacher receives ring-buffer scrollback then live stream, no duplicated bytes.
+- Flow control: slow consumer triggers pause at high watermark; resume at low watermark; fast consumer unaffected.
+- Resize: latest-active-client policy applied; both viewers reflow to broadcast size.
+- SSE: state transition emits one throttled event; reconnect with lastEventId replays missed transitions.
+**Verification:** WS tests run against a real server instance on an ephemeral port (never 4040), per the worktree-testing learning.
+
+### U11. Dashboard terminal UI and task-card states
+
+**Goal:** Terminal tab on the task detail view, live xterm terminal, posture chip, waiting/needs-attention badges and banner.
+**Requirements:** origin R6 (visibility), R11, R14, R21 (posture surfacing); F2.
+**Dependencies:** U10.
+**Files:** `packages/dashboard/app/components/SessionTerminal.tsx` (new shared component + CSS), `packages/dashboard/app/components/TaskDetailModal.tsx` (`terminal` TabId), `packages/dashboard/app/components/TaskCard.tsx` (state badge), `packages/dashboard/app/components/SessionNotificationBanner.tsx` (waiting-on-input entries), `packages/dashboard/app/components/__tests__/SessionTerminal.test.tsx`, `packages/dashboard/app/components/__tests__/TaskDetailModal.terminal-tab.test.tsx`, `packages/dashboard/app/components/__tests__/TaskCard.cli-states.test.tsx`.
+**Approach:** `@xterm/xterm` 6.x + fit/webgl/unicode11 addons, lazy-loaded (keep it out of the main bundle); custom WS bridge with ACK flow control; WebGL context-loss fallback to DOM renderer. xterm configured defensively (no clipboard-write handling for `OSC 52`, link handler restricted to http/https) as the client-side layer of the U10 output hardening.
+
+Tab visibility matrix: starting/execute-active → live terminal; execute-done but session resumable → scrollback replay with a "session idle" header; validator/planning one-shot → read-only live stream with a visible Read-only badge in the terminal header; in-review/done (PTY reaped) → scrollback replay with a "session ended" state; no recorded session → tab hidden. needsAttention variants carry pinned copy and actions: `userExited` → "Agent exited before completing — Advance / Retry / Cancel task"; `authFailed` → "CLI authentication failed — Re-authenticate (opens adapter settings) / Retry"; resume-exhausted → "Couldn't resume the session — Relaunch fresh / Cancel task". `SessionNotificationBanner` is explicitly extended: its closed `TYPE_ICONS`/`TYPE_LABEL_KEYS` union gains a `cli-agent` session type (single Terminal icon for all adapters) and the new action verbs — reusing the banner without this extension crashes on the unknown type. Confirm-to-advance strip per U10. Posture chip states: baseline = neutral chip with adapter name + mode; elevated = warning-color chip with shield icon naming the elevated flag; clicking opens a tooltip listing the resolved posture with a link to adapter settings (chip spec shared by U12 chat header and U13 mobile). Task card shows waiting-on-input / needs-attention badges distinct from staleness/stall badges (which are suppressed in these states per U8). All strings through the i18n layer (namespaces.json, app-relative catalog imports, canonical CSS tokens).
+**Patterns to follow:** plugin-tab injection precedent in `TaskDetailModal` for tab plumbing; `SessionNotificationBanner` shape; i18n foundation learning.
+**Test scenarios:**
+- Covers F2. waitingOnInput SSE event → card badge + banner entry; answering (state→busy) clears both.
+- Terminal tab appears only for cli-agent tasks; read-only flag disables input for one-shot sessions.
+- Posture chip reflects the session's recorded autonomy posture, including elevated-flag styling.
+- needs-attention state renders the pinned per-variant copy and actions (userExited / authFailed / resume-exhausted); banner renders the cli-agent type without crashing (union extension).
+- Tab visibility matrix: each lifecycle phase renders its specified state (live / replay / read-only badge / session-ended / hidden).
+- Confirm-to-advance strip renders for generic-tier idle; Advance moves the task on; Not yet re-arms the idle timer.
+- i18n: new strings resolve through catalogs (missing-key guard).
+**Verification:** component tests green; manual cross-browser smoke (WebGL fallback) is an implementation-time checklist item.
+
+### U12. Chat hybrid transcript and raw-terminal toggle
+
+**Goal:** CLI-backed chat sessions: structured transcript from native telemetry persisted as chat history, composer injection with queueing, raw-terminal toggle.
+**Requirements:** origin R15, R16; F3; AE7.
+**Dependencies:** U3, U4, U10.
+**Files:** `packages/dashboard/src/chat.ts` (CLI-backed session path), `packages/core/src/chat-store.ts` (native session linkage), `packages/dashboard/app/components/ChatView.tsx` + chat hooks (transcript/terminal toggle, composer queue state), `packages/dashboard/src/__tests__/chat-cli-sessions.test.ts`, `packages/dashboard/app/components/__tests__/ChatView.cli-toggle.test.tsx`.
+**Approach:** A chat session selecting a CLI executor spawns (or resumes) a session in a configured working directory; adapter transcript events map to `chat_messages` rows (user/assistant/tool-summary granularity — fine-grained tool events stay in the terminal, not the transcript), with the shared `redactSecrets` pass (extracted to `@fusion/core` in U16) applied to transcript text before persistence — durable chat rows must not become a secret store (see Risks). Characterize what the pass covers as part of this unit (its known patterns vs gaps) so the deferral of deeper heuristics is scoped against a measured baseline. SSE `chat:message:added` streams them as today. Composer sends route through the inject API; while busy, sends queue with visible state (flush decisions re-fetch authoritative session state — never a cached flag). Raw-terminal mode swaps the message list for the SessionTerminal component and hides the composer; toggle restores transcript. Generic-tier sessions render terminal-only with no toggle (the transcript affordance is absent, not empty).
+**Patterns to follow:** `ChatStore`/`chat_messages` persistence; Generation/Queued-message concepts (CONCEPTS.md); queued-chat-flush learning.
+**Test scenarios:**
+- Covers AE7 / F3. Toggle between transcript and terminal reflects one underlying session; transcript rows persist and reload after session end.
+- Transcript mapping: adapter transcript fixture produces expected chat_messages sequence; tool noise excluded.
+- Composer queue: send while busy → queued indicator; flush on done; flush decision uses re-fetched state.
+- Generic tier: no transcript pane, no toggle, terminal renders directly.
+- Redaction: transcript fixture containing a bearer/API token is redacted before landing in chat_messages; a token spanning a chunk split (prefix in one chunk, value in the next) is still caught; an env-dump fixture (KEY=VALUE lines) is redacted.
+- Mobile viewport: composer/keyboard behavior keeps existing mobile chat tests green.
+**Verification:** chat integration tests prove transcript persistence reuses chat history storage (no parallel store).
+
+### U13. Mobile terminal interaction
+
+**Goal:** Interactive terminal on the mobile surface with a usable input model.
+**Requirements:** origin R14; AE6.
+**Dependencies:** U11.
+**Files:** `packages/dashboard/app/components/SessionTerminal.mobile.css` (or co-located mobile styles), mobile input bar component within `SessionTerminal.tsx`, `packages/dashboard/app/components/__tests__/SessionTerminal.mobile.test.tsx`.
+**Approach:** Same web component (mobile is the Capacitor-wrapped dashboard). xterm's hidden-textarea input is unreliable on mobile: render a visible input field + accessory key bar that forwards into the session, applying the established iOS patterns (pointerdown/mousedown preventDefault on bar keys, fixed-footer behavior when the keyboard opens, visualViewport scale guard). Accessory bar semantics: Esc (`0x1B`), Tab (`0x09`), arrows (ANSI cursor sequences), and a **sticky Ctrl modifier** — tap Ctrl, then the next key tapped combines (Ctrl-C `0x03`, Ctrl-D `0x04`, Ctrl-Z `0x1A`); a dedicated Ctrl-C shortcut also sits on the bar. Bar keys write directly to the session input path as deliberate control input (exempt from U2's injected-text neutralization, which governs composed/injected strings, not user keystrokes). Mobile defaults to read-mostly with the input bar; full inline xterm typing is progressive enhancement. If interactive input proves unshippable within the unit, the defined fallback is read-only stream + input field (decision pre-made in origin's open question resolution).
+**Patterns to follow:** `useMobileKeyboard` + iOS composer survival patterns; mobile breakpoint conventions.
+**Test scenarios:**
+- Accessory bar keys emit correct control sequences into the session.
+- Keyboard-open does not occlude the input bar (fixed-footer behavior); pinch-zoom guard respected.
+- Covers AE6 (mobile leg): mobile attach renders the same live session bytes as desktop.
+**Verification:** mobile-viewport component tests green; on-device smoke is an implementation-time checklist item.
+
+### U14. TUI terminal attach
+
+**Goal:** The Ink TUI can open a task's CLI session as a full-screen passthrough.
+**Requirements:** origin R14.
+**Dependencies:** U10.
+**Files:** `packages/cli/src/commands/dashboard-tui/terminal-attach.ts` (new — WS client + passthrough), wiring in `packages/cli/src/commands/dashboard-tui/app.tsx`, `packages/cli/src/commands/dashboard-tui/__tests__/terminal-attach.test.ts`.
+**Approach:** Suspend-and-handoff, not embedding: on opening a session, suspend Ink rendering, enter the alternate screen, run a raw passthrough loop (stdin raw mode → WS input frames; WS data frames → stdout; SIGWINCH → resize frames); on exit keystroke (e.g. a documented detach chord), leave alt-screen and remount Ink. The passthrough applies the same U10 output-neutralization set before writing to the host TTY — the host terminal honors more sequences than xterm.js and verbatim passthrough of an untrusted stream is the riskiest leg (see Risks). WS client is net-new for the TUI (HTTP-only today) — minimal client with the daemon token. CJK double-width and raw-mode ref-counting handled per the i18n/Ink learnings.
+**Patterns to follow:** Ink `useStdin().setRawMode` conventions; alt-screen handoff pattern (vim/less model) from research.
+**Test scenarios:**
+- Passthrough loop frames stdin bytes into WS input messages and writes data frames to stdout verbatim (fixture transport).
+- Detach chord restores Ink rendering and leaves alt-screen; raw-mode refcount returns to baseline.
+- Resize propagates as a resize frame.
+- Output neutralization (full U10 set): data frames containing `OSC 52` clipboard-write, `OSC 8` with a non-http/https scheme, and device-status queries are all sanitized before reaching stdout — parallel assertions to U10's.
+- Error path: WS drop mid-attach surfaces a message and restores the TUI cleanly.
+**Verification:** unit tests on the passthrough loop with a fake transport; manual TTY smoke is an implementation-time checklist item.
+
+### U15. Adapter settings, autonomy approval gate, and node editor config
+
+**Goal:** Settings surfaces for adapter launch config and autonomy posture; workflow node editor support for cli-agent executor selection and attention behavior.
+**Requirements:** origin R2, R11, R13, R21, R22.
+**Dependencies:** U2, U7.
+**Files:** `packages/core/src/global-settings.ts` (cliAgents settings shape), `packages/dashboard/app/components/SettingsModal.tsx` (adapter settings section), `packages/dashboard/app/components/WorkflowNodeEditor.tsx` (executor: cli-agent + adapter + notification config), `packages/dashboard/src/routes/cli-agent-settings.ts` (new, incl. approval route), `packages/core/src/__tests__/global-settings-cli-agents.test.ts`, `packages/dashboard/app/components/__tests__/WorkflowNodeEditor.cli-agent.test.tsx`, `packages/dashboard/src/routes/__tests__/cli-agent-settings-route.test.ts`.
+**Approach:** Per-adapter settings (command override, extra args, autonomy mode, env allowlist additions) in `GlobalSettings` with shipped defaults defined by each adapter. Autonomy modes above the adapter baseline require a stored per-project approval (route + confirmation UI), mirroring the workflow raw-command approval precedent. The gate covers the adjacent free-form channels, not just the autonomy-mode field: each adapter defines an elevation detector over the **fully resolved argv + env** (e.g. `--dangerously-skip-permissions` smuggled via extra args, autonomy-toggling env vars via allowlist additions), and command override to an arbitrary path is itself a privileged setting — elevation expressed through any channel routes through the same approval or is rejected at the write boundary. The posture chip derives from the resolved argv+env, never from the autonomy-mode field alone, and the effective posture is denormalized onto session records at launch (U1). Approving principal in v1: the holder of the daemon token (the single workspace owner) grants approvals; a role-based check is deferred with the rest of the authz model (see Scope Boundaries). Node editor exposes executor kind, adapter picker (with tier labels: native/hybrid/generic), and waiting-on-input notification behavior. Validation at the settings write boundary (Global Settings convention). i18n for all new strings.
+**Test scenarios:**
+- Settings round-trip: adapter config persists, merges with defaults, invalid values dropped at the write boundary.
+- Approval gate: elevated autonomy mode without approval fails launch with a clear error; approved project launches and records posture.
+- Bypass closure: `--dangerously-skip-permissions` added via extra args (not the autonomy field) trips the gate; an autonomy-toggling env var via allowlist addition is rejected/gated; posture chip reflects effective argv+env posture.
+- Node editor: selecting cli-agent surfaces adapter + notification fields; config lands in node config; per-task override path verified.
+- Env additions: user-added allowlist entries reach the child env; service credentials still excluded.
+**Verification:** settings/route/editor tests green; the approval gate is exercised by a U7 integration test variant.
+
+---
+
+## Scope Boundaries
+
+Carried from origin — deferred for later:
+- Agent-side completion protocol ("run this command when done") — reliability layer on top of telemetry.
+- CLI executors for arbitrary workflow script/prompt nodes.
+- Structured transcripts for generic-tier CLIs (screen-output parsing).
+- Multi-user collaborative co-driving semantics (presence, input arbitration beyond FIFO serialization).
+
+### Deferred to Follow-Up Work
+
+- Plugin-contributed CLI adapters via plugin-sdk (the registry interface is designed for it; the contribution point + registration checklist ships separately).
+- Per-user / workspace-member authorization and a real admin role. **This is an explicit narrowing of origin R17/R21**: the origin commits access scoped to the "owning authenticated user or workspace member" and "workspace-administrator editable" flags; v1's single daemon-token + approval-gate model satisfies neither for multi-user workspaces — it is adequate for the single-developer deployment the persona targets, and inadequate where multiple people share a daemon token (any token holder can attach and inject into any session). Input-frame attribution (U10) is the v1 accountability floor until per-user auth ships.
+- Web/OS push notifications for waiting-on-input (in-app banner + badge in v1).
+- Headless-xterm serialize-addon snapshot replay (v1 uses raw byte ring-buffer replay; revisit if mid-sequence truncation artifacts appear).
+- tmux/broker-based PTY liveness across engine restarts (v1 is resume-the-CLI by design).
+- Advanced transcript redaction heuristics and retention policy enforcement (v1 applies the existing `redactSecrets` pass before persistence and inherits session access controls; deeper detection and retention are settings follow-ups).
+
+---
+
+## System-Wide Impact
+
+- **Scheduler/self-healing semantics:** new session states interact with stuck detection, hard-cancel, and restart recovery (U7/U8); regressions here affect non-CLI tasks too — the suppression and eligibility predicates are additive guards, not rewrites.
+- **Packaged binaries:** node-pty native modules already ship for the dashboard; engine-side PTY use must keep the Bun-binary native-asset handling intact (release pipeline gotchas learning). `@xterm/*` additions are lazy-loaded client code.
+- **Auth surface:** one new localhost hook endpoint and CLI-session WS attach. This is **new local attack surface — localhost is not a trust boundary**: any local process or browser page can reach 127.0.0.1, so the hook endpoint requires per-session high-entropy tokens + Origin/Host rejection, and PTY attach requires single-use tickets + Origin allowlisting (see Risks).
+- **i18n:** new namespaces/strings across dashboard and TUI; CI catalog guards apply.
+- **Changesets:** published CLI surface changes (TUI attach) require a changeset; private packages do not.
+
+---
+
+## Risks & Dependencies
+
+- **Untrusted terminal output rendering (high):** CLI PTY output is attacker-influenceable (the agent renders repo content, tool output, web fetches) and reaches three terminal emulators — xterm web/mobile and the host TTY via TUI passthrough. Hostile sequences can write the clipboard (`OSC 52`), plant `javascript:`/`file:` hyperlinks (`OSC 8`), or trigger device-query auto-responses that forge input into the shared FIFO. Mitigation: server-side neutralization in the WS bridge (U10), defensive xterm config (U11), and the same neutralization set on the TUI passthrough (U14) — the host-TTY leg is the riskiest and is never verbatim.
+- **Local hook-endpoint spoofing (high):** telemetry drives pipeline advancement toward merge (origin R20), so a forged `Stop`/completion POST from any local process or a CSRF-ing browser page could advance incomplete work, suppress the stall detector, or wedge sessions. Mitigation: high-entropy per-session tokens bound server-side and invalidated on session end (U3), Origin/Host rejection and payload caps on the route (U17). The token's at-rest exposure in session-scoped hook config is an accepted, lifetime-bounded risk.
+- **PTY input from a hostile browser tab (high):** an origin-unchecked WS upgrade with a URL-borne long-lived token would grant keystroke injection into privileged PTYs (arbitrary command execution in the worktree at the session's autonomy posture). Mitigation: Origin allowlist on the cli-agent upgrade, short-lived single-use session-scoped attach tickets distinct from the daemon token (U10).
+- **Autonomy-gate bypass via adjacent settings (high):** extra-args, command override, and env-allowlist additions can encode the very elevation the approval gate controls, leaving the posture chip false-safe. Mitigation: per-adapter elevation detection over resolved argv+env, command-override treated as privileged, chip derived from effective posture (U15).
+- **Transcripts as a durable secret sink (medium):** CLI agents routinely print tokens and env dumps; persisting transcripts to queryable chat rows turns transient scrollback into durable storage. Mitigation: the shared `redactSecrets` pass (extracted to `@fusion/core` in U16) runs on transcript text before persistence, with cross-chunk and env-dump coverage characterized in U12; deeper heuristics and retention policy remain follow-ups.
+- **CLI version churn (high):** hook rosters, notify payloads, session file layouts are version-sensitive (Claude `PermissionRequest` is newer; Codex `~/.codex/sessions/` layout is community-sourced). Mitigation: adapters probe capabilities at launch, degrade tier honestly, and pin verification smoke-tests per CLI as implementation checklist items.
+- **Codex waiting-state detection (medium):** PTY prompt-pattern heuristics may misclassify across Codex UI updates. Mitigation: hybrid tier marks waiting-detection as heuristic in capability flags; stall backstop bounds the failure cost.
+- **Mobile interactive input (medium):** xterm mobile input is a known-hard area. Mitigation: visible input field + accessory bar is the primary input model; read-only fallback pre-agreed.
+- **Engine/dashboard process boundary (medium):** session manager lives in the engine but HTTP/WS/SSE serve from the dashboard (the engine has no HTTP server); telemetry therefore round-trips CLI → dashboard route → engine hub. The U2 async attach interface and engine-owned flow control keep this seam explicit so a future process split stays credible — the EventEmitter shape of the existing terminal service is deliberately not reused.
+- **node:sqlite resilience:** new table inherits the DB-corruption posture; store code must tolerate recovery (existing patterns).
+
+---
+
+## Open Questions
+
+Deferred to implementation (execution-time discovery):
+- Exact hook/notify payload field availability per pinned CLI versions — verified by scaffold-time smoke tests against installed binaries, per the SDK-authoritative learning.
+- Pi `--mode json` event-line schema and whether it applies to the interactive launch path (fall back to session-JSONL tail if not).
+- Generic-tier idle thresholds and prompt-pattern sets — tuned against recorded fixtures during implementation.
+- Ring-buffer sizing and ACK watermark values — start at researched defaults (256KB–1MB ring; 128KB/16KB watermarks) and tune.

 CLI nodes can run arbitrary commands (not just named scripts); the first run of an exact command pauses the task for explicit user approval. The task modal's input/approval banner is interactive — reply-and-resume for user-input nodes, approve-and-run for CLI commands.
 
-Agents reach workflows too: new `fn_workflow_list` and `fn_workflow_select` task tools give agents the same list/select capability as the dashboard picker. Built-in workflows are now read-only in the editor (palette/inspector disabled, with a "Duplicate to edit" action), and a node's "Auto-approve requests" toggle now actually bypasses the CLI first-run approval pause.
+Agents reach workflows too: the `fn_workflow_list`, `fn_workflow_get`, `fn_workflow_select`, `fn_workflow_create`, `fn_workflow_update`, and `fn_workflow_delete` tools (plus `fn_trait_list` for the column vocabulary) give agents the same author/list/select capability as the dashboard. These are exposed not only to the task executor but also to the chat and planning agents, so you can author and edit workflows directly in a chat or planning conversation; a guard test locks all six tool names to each lane to prevent silent exposure drift. Built-in workflows are now read-only in the editor (palette/inspector disabled, with a "Duplicate to edit" action), and a node's "Auto-approve requests" toggle now actually bypasses the CLI first-run approval pause.
 
 Also fixes a latent persistence bug where `pausedReason` was written to the in-memory task and read by queries but never stored by the task upsert or mapped back on read — so it was lost on every reload. This silently broke any pause/resume that depends on the reason (workflow CLI-approval and await-input nodes, token-budget pauses, worktrunk failures). The approve-CLI endpoint now derives the approved command solely from the task's pausedReason (ignoring any caller-supplied command), await-input nodes only resume when this node actually paused the task (not on a pre-existing steering comment), and write-capable custom nodes are refused until a task worktree exists so they never mutate the shared repo root.

+/**
+ * WorkflowSettingsPanel — the workflow editor's typed-settings surface (U6, R5).
+ * Sibling to {@link WorkflowFieldsPanel} and {@link WorkflowColumnPanel}: lives
+ * alongside the canvas in {@link WorkflowNodeEditor}. It is ONE panel with an
+ * internal TAB PAIR (KTD-1/KTD-2):
+ *
+ *  - "Definitions" — declare/edit the workflow's typed settings (id, name, type,
+ *    default, options for enum kinds, description, widget). Edits mutate
+ *    `ir.settings` through the editor's shared `settings`/`onChange` state and
+ *    ride the editor's existing IR Save flow; validation runs server-side at save
+ *    (parseWorkflowIr) and surfaces through the editor's error band. Built-in
+ *    workflows render this tab read-only (declarations are not editable; values
+ *    are — KTD-2).
+ *
+ *  - "Values" — per-PROJECT setting values for the project active when the panel
+ *    opened. Values batch in panel state and commit through a DEDICATED "Save
+ *    values" button that sends ONE PATCH to the value authority route — never
+ *    per-field writes, never fused with the IR Save (the two write authorities
+ *    stay separate, KTD-2). Per-field typed rejections render on the matching
+ *    rows. Below the live list, a collapsible "Orphaned values" disclosure (KTD-6
+ *    drop-on-orphan) shows stored values that no longer validate against the
+ *    current declarations, each with a delete affordance (null patch).
+ *
+ * The Values tab BINDS the projectId at open. If the dashboard's active project
+ * changes while the editor is open, it shows a stale-context notice instead of
+ * silently rebinding writes. With no active project it shows a requires-project
+ * state and no write path.

+## Workflow settings: declarations vs. values
+
+Workflow settings split into two surfaces (the same split as custom task fields, one level up):
+
+- **Declarations** (the typed schema) live in the workflow IR's `settings` array and are authored with `fn_workflow_create` / `fn_workflow_update`. Built-in workflow declarations cannot be edited (the store's built-in guard rejects the IR edit with a `WorkflowIrError`/built-in error surfaced through the tool result).
+- **Values** (the per-`(workflow, project)` data) are read/written with `fn_workflow_settings`. Built-in workflow **values** are writable so each project can tune `builtin:coding` differently.
+
+Declare a setting (custom workflow):
+
+```jsonc
+// fn_workflow_create
+{
+  "name": "QA",
+  "ir": {
+    "version": "v2",
+    "name": "QA",
+    "columns": [{ "id": "intake", "name": "Intake", "traits": [] }],
+    "nodes": [],
+    "edges": [],
+    "settings": [
+      { "id": "reviewHandoffPolicy", "name": "Review handoff", "type": "enum",
+        "default": "disabled",
+        "options": [
+          { "value": "disabled", "label": "Disabled" },
+          { "value": "always", "label": "Always" }
+        ] }
+    ]
+  }
+}
+```
+
+Write a value (built-in workflow VALUE — accepted even though built-in declarations are read-only):
+
+```jsonc
+// fn_workflow_settings
+{ "action": "set", "workflow_id": "builtin:coding",
+  "values": { "workflowStepTimeoutMs": 600000, "reviewHandoffPolicy": "always" } }
+```
+
+An invalid value (e.g. an enum violation) is rejected with a typed list and persists nothing:
+
+```jsonc
+// returns isError:true with details.rejections:
+// [{ "code": "enum-violation", "settingId": "reviewHandoffPolicy", "message": "..." }]
+```
+
+Read values — `effective` is what the engine actually consumes (declaration defaults filled in, orphaned values dropped); `stored` is the raw override map:
+
+```jsonc
+// fn_workflow_settings
+{ "action": "get", "workflow_id": "builtin:coding" }
+// → { "workflowId": "builtin:coding",
+//     "stored":    { "workflowStepTimeoutMs": 600000 },
+//     "effective": { "workflowStepTimeoutMs": 600000, "reviewHandoffPolicy": "disabled", ... } }
+```

Subject: [PATCH 029/112] Fix quality-backfill suites broken by fast-tests x
 workflow-columns merge race
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Main went red when the fast-tests quality-backfill projects (PR #1385)
landed alongside the workflow-columns stream (PR #1424) — the new test
projects were written against pre-stream code:

- TaskFieldsSection.css toggle knob used background: #fff, violating the
  theme-token assertion in AgentListModal's styling-parity test; use
  var(--card) per the SkillsView toggle convention
- ListView.test.tsx api mock lacked fetchBoardWorkflows (TaskDetailModal
  now calls it on mount)
- chat.test.ts and routes-agent-import.test.ts @fusion/core mocks lacked
  registerTraitHookImpl (engine merge-trait registers hooks at import)
- auto-merge-toggle-blank.mobile and board-mobile-initial-render used
  vi.runAllTimers(), which never terminates now that sse-bus starts a
  keepalive setInterval; use vi.runOnlyPendingTimers()

Both quality-backfill projects now pass fully: 7151/7151 across 414
files.

Subject: [PATCH 030/112] feat(engine): add CliAgentAdapter interface and
 CliSessionManager (U2)

Engine-owned PTY lifecycle for CLI agent sessions:
- adapter.ts: CliAgentAdapter interface (launch/env-allowlist builders,
  capability flags, readiness detection, injection formatter, resume builder,
  telemetry wiring) + CliAdapterRegistry with typed unknown/duplicate errors.
- session-manager.ts: CliSessionManager owning node-pty processes via the U16
  shared loader. Byte-bounded scrollback ring (default ~512KB), single
  serialized write queue shared by injections + user input (FIFO, deferral in
  quiet windows), latest-active-client resize, scoped-SIGKILL process registry
  on process exit (never port 4040), explicit async attach interface
  (scrollback + AsyncIterable<Uint8Array> + write/resize/detach),
  requestPause/requestResume watermark hooks, separate concurrency pool with
  typed CliConcurrencyLimitError at the ceiling.
- Security: bracketed paste only when ?2004h observed; unconditional control-char
  neutralization on the raw path; user keystrokes bypass neutralization.
- Persists lifecycle into the U1 CliSessionStore (create on spawn, update
  state/termination).

+/**
+ * CliAgentAdapter interface and registry (CLI Agent Executor, U2).
+ *
+ * An adapter teaches the engine how to drive one CLI coding agent (Claude Code,
+ * Codex, Droid, Pi, or a generic PTY fallback) inside an engine-owned PTY. The
+ * adapter is pure policy — it declares *how* to launch, *how* to recognize
+ * readiness, *how* to format an injected prompt, *how* to resume — while the
+ * CliSessionManager owns the actual node-pty process lifecycle.
+ *
+ * Design notes (KTD):
+ * - Engine-owned abstraction, NOT an AgentRuntime plugin: the runtime contract
+ *   is API-shaped and cannot model a PTY stream / co-driving / resume.
+ * - Adapters declare honest capability flags so surfaces can render tier
+ *   differences (a generic adapter with everything disabled behaves like the
+ *   heuristic tier).
+ * - The env builder follows the ACP hardening convention: NEVER inherit
+ *   `process.env` wholesale; copy only an explicit allowlist.

+/**
+ * CliSessionManager — engine-owned PTY lifecycle for CLI agent sessions
+ * (CLI Agent Executor, U2).
+ *
+ * Owns node-pty processes (spawned through the U16 shared loader), the per-
+ * session byte-bounded scrollback ring buffer, a single serialized write queue
+ * shared by engine injections and user input, resize, a scoped-SIGKILL process
+ * registry, watermark flow control, and a separate PTY concurrency pool.
+ *
+ * Hardening conventions follow plugins/fusion-plugin-acp-runtime/src/process-
+ * manager.ts:
+ * - Env allowlist: NEVER inherit `process.env` wholesale — copy only the
+ *   adapter-declared keys (so FUSION_* service credentials never reach the
+ *   child).
+ * - Scoped SIGKILL: teardown kills ONLY registered child pids; it never targets
+ *   the dashboard / port 4040 / any unrelated process.
+ * - Self-cleaning registry: a process removes itself on exit.
+ *
+ * Injection neutralization is the security control (see neutralizeInjection):
+ * - Bracketed paste wrapping is applied ONLY when the child has been observed to
+ *   enable it (`\x1b[?2004h` seen and not since disabled).
+ * - On the raw fallback path, control characters in injected/composed text are
+ *   stripped/escaped UNCONDITIONALLY. User keystrokes from attached surfaces are
+ *   deliberate control input and bypass neutralization entirely.
+ *
+ * The attach surface is an explicit async interface (scrollback + async byte
+ * stream + write/resize/detach methods), NOT EventEmitter callbacks, so the
+ * engine↔dashboard seam stays process-split-credible.

Subject: [PATCH 032/112] feat(engine): add cli-agent telemetry hub and session
 state machine (U3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pure engine code (no HTTP) for the CLI agent executor:

- state-machine.ts: authoritative per-session state machine implementing the
  HTD diagram (starting→ready→busy⇄waitingOnInput→done; done→busy follow-up;
  dead-classification choice → killed/userExited/authFailed/resuming; resume cap
  of 2 with backoff → needsAttention). Positive completion is distinct from idle
  (idle never produces done); inactivity stall backstop re-armed by output/
  telemetry events (no fixed turn timeout); termination classification helper for
  all five paths; per-turn latches reset between turns. Persists every transition
  via CliSessionStore (the transient `resuming` machine state maps onto the U1
  `dead` store enum) and exposes a throttled `onStateChange` subscription for the
  later SSE bridge — no dashboard imports.

- telemetry-hub.ts: in-process ingestion contract (ingest(sessionId, event)) for
  the U17 route and log-tailing adapters. Mints high-entropy per-session hook
  tokens (issueToken/validateToken/invalidate); rebuilds the registry only from
  live sessions in CliSessionStore so stale tokens for non-live sessions never
  validate; a token validates only for its own session. Bounds everything
  ingested: per-event size caps, per-turn count caps (lifecycle events exempt),
  ANSI/control stripping before pattern matching, and secret redaction that
  survives chunk boundaries via a held-back carry window (redactSecrets from
  @fusion/core).

Tests: 35 new (state-machine.test.ts, telemetry-hub.test.ts) covering AE1/AE2,
stall backstop, all termination paths, resume caps, token registry, two-turn
latch reset, oversized capping, ANSI stripping, and cross-chunk redaction.

+ *   ready → busy                (prompt injected)
+ *   busy → waitingOnInput       (permission / question signal)
+ *   waitingOnInput → busy       (user answers)
+ *   busy → done                 (POSITIVE completion signal — idle NEVER does this)
+ *   done → busy                 (follow-up; resume first if the PTY was reaped)
+ *   busy → dead                 (PTY end / engine death)
+ *   waitingOnInput → dead       (PTY end / engine death)
+ *   dead → {killed|userExited|authFailed|resuming}   (classification choice)
+ *   resuming → busy             (native resume ok)
+ *   resuming → needsAttention   (2 attempts exhausted)
+ *   userExited → needsAttention (advance / retry / cancel prompt)
+ *   authFailed → needsAttention (re-authenticate message)
+ *
+ * Key behaviors (KTD — completion gating, termination taxonomy, stall backstop):
+ * - Positive completion is distinct from idleness. `signalDone()` advances to
+ *   `done`; output progress / idleness NEVER advance to done.
+ * - Stall backstop: no output progress past a configurable threshold WITHOUT a
+ *   done/waiting signal → needsAttention. The inactivity watchdog is re-armed by
+ *   any telemetry/output event (no fixed turn timeout); `waitingOnInput`
+ *   suppresses it (expected idleness).
+ * - Termination classification helper maps the manner of a PTY end onto the
+ *   taxonomy (killed / userExited / crashed / authFailed / engineDeath).
+ * - Resume attempt cap = 2 with backoff metadata; exhaustion → needsAttention.
+ * - Per-turn latches/budgets reset between turns (a new busy turn re-arms the
+ *   completion latch so a second turn through one handler is tracked cleanly).
+ *
+ * Persistence + observability:
+ * - Every transition persists through `CliSessionStore.updateSession` (state +
+ *   terminationReason + resumeAttempts written atomically by the store).
+ * - A throttled `onStateChange` callback is exposed for the SSE bridge to
+ *   subscribe to later. This module NEVER imports dashboard code.

+/**
+ * TelemetryHub — in-process telemetry ingestion + per-session token registry
+ * (CLI Agent Executor, U3).
+ *
+ * The hub is the single in-process sink for normalized telemetry events about a
+ * CLI agent session. It is consumed later by:
+ * - the dashboard hook route (U17), which forwards validated hook POSTs, and
+ * - log-tailing adapters (Codex rollout, Pi JSONL) that synthesize events.
+ *
+ * The engine has NO HTTP server — this module is pure engine code. It performs
+ * NO networking; it only validates tokens and ingests already-delivered events.
+ *
+ * Responsibilities (KTD — telemetry tiering, completion gating, security):
+ * - Token registry: mint a high-entropy per-session hook token at spawn
+ *   (`issueToken`), validate it scoped to its own session (`validateToken`), and
+ *   invalidate it on session end (`invalidate`). On construction the registry is
+ *   rebuilt ONLY from sessions still live in `CliSessionStore`, so stale on-disk
+ *   tokens for non-live sessions never validate after an engine restart.
+ *   A forged completion using another session's token is rejected because a
+ *   token validates only for the session it was issued to.
+ * - Normalization + bounding: per-event payload size caps, per-turn event count
+ *   caps, ANSI / control stripping BEFORE any pattern matching, and secret
+ *   redaction that survives chunk boundaries (a token split across two chunks is
+ *   still caught — uses `redactSecrets` from @fusion/core on the joined tail).
+ * - Routing: maps a normalized event onto the session's state machine
+ *   (sessionStart→ready, busy→signalBusy, waitingOnInput→signalWaitingOnInput +
+ *   notification dispatch, done→signalDone, outputProgress→signalOutputProgress).
+ *   Idle/output NEVER advances to done — that gating lives in the state machine.

Subject: [PATCH 033/112] feat(core): one-time hard-move migration of
 workflow-policy settings to workflow setting values

30 moved keys (step execution, review/approval, per-phase model lanes) leave
DEFAULT_PROJECT_SETTINGS; marker-gated idempotent per-project migration writes
customized values to every in-use (workflowId, projectId); stale-writer guard;
tombstone allowlist derived from the builtin catalog.

+/**
+ * Tombstone allowlist for the U4 hard-move (KTD-5).
+ *
+ * `MOVED_SETTINGS_KEYS` is the single, authoritative record of the settings keys
+ * that left `DEFAULT_PROJECT_SETTINGS` and now live exclusively as **workflow
+ * setting values** per `(workflowId, projectId)`. It is derived directly from the
+ * built-in workflow declaration catalog (`BUILTIN_WORKFLOW_SETTINGS`) so the move
+ * has exactly one source of truth — a key is "moved" iff a built-in workflow
+ * declares it. Adding/removing a key from the catalog automatically reflows the
+ * tombstone list, the migration write target, and the stale-writer guard.
+ *
+ * What the tombstone shields (KTD-5, R8):
+ *   - the project/global settings WRITE paths (`updateSettings` /
+ *     `updateGlobalSettings`) — incoming moved keys from stale writers are silently
+ *     dropped, never persisted (they would otherwise re-materialize in raw
+ *     storage and, via the default re-injection trap, silently override the
+ *     migrated workflow value);
+ *   - the migration's raw-key null-out (it nulls exactly these keys from the
+ *     persisted project + global stores);
+ *   - (in U5) settings export v2 / cross-node sync diff / v1 import.
+ *
+ * ── TYPE-vs-SCHEMA SPLIT (deliberate, documented per the U4 plan) ──────────────
+ * The moved keys are REMOVED from `DEFAULT_PROJECT_SETTINGS` (so they vanish from
+ * `PROJECT_SETTINGS_KEYS` / `isProjectSettingsKey` / the save-split), but the
+ * corresponding fields are RETAINED on the `ProjectSettings` / `Settings`
+ * TypeScript interfaces. This is intentional: the engine still types its ~20 flat
+ * `settings.<movedKey>` read sites and the U3 effective-settings merge off
+ * `Partial<Settings>`, so dropping the fields from the type would break those
+ * call sites. The schema MEMBERSHIP (key lists / predicates / persistence
+ * filters) is the thing that must not include moved keys — not the type shape.
+ *
+ * NOTE on `buildTimeoutMs`: it has NO reader anywhere in the engine, so it fails
+ * the per-task-reader rule (KTD-5 / catalog-shrink) and was removed from
+ * `BUILTIN_WORKFLOW_SETTINGS` entirely. It therefore stays a plain project
+ * setting and is intentionally ABSENT from this list.

+   *      project `config.settings`, and set the marker. (The async validation /

+# feat: Per-column agent assignment — permanent agents for workflow columns
+
+## Summary
+
+Let a workflow-defined column name a **permanent agent** from the agent registry, with a per-column mode: **defer** (column agent is the default for work in that column that carries no agent/model settings of its own) or **override** (column agent wins over node-level and task-level agent/model settings). The binding applies to all session-running work attributable to the column — custom prompt/gate/script nodes, the execute seam's coding session, and step-execute sessions — and the column-resolved agent becomes the *principal* for action gating, heartbeat deferral, and session-restart detection, not merely a model source. The built-in default workflow carries no column agents and stays byte-identical (parity oracle).
+
+---
+
+## Problem Frame
+
+The columns/traits track (`docs/plans/2026-06-03-003-feat-workflow-custom-columns-traits-plan.md`, PR #1418) made columns first-class workflow IR entities with composable traits, and the step-inversion track (active on this branch) is making steps workflow-modelable. But **who does the work** in a column is still decided node-by-node or task-by-task: a custom node can set `executor: "agent"` + `agentId` in its config (`packages/engine/src/executor.ts:4546`), and a task can carry `assignedAgentId` / `modelProvider` + `modelId` — there is no way to say "everything that runs in my Review column runs as the senior-reviewer agent."
+
+A user authoring a workflow with specialized columns (planning, implementation, review, docs) wants to staff each column once and have every card flowing through inherit that staffing — while still being able to either respect finer-grained node settings (defer) or enforce the column's agent unconditionally (override).
+
+---
+
+## Requirements
+
+**Binding & precedence**
+
+- R1. A workflow column can optionally name an agent from the agent registry plus a mode, `defer` or `override`.
+- R2. Defer: the column agent applies only when the work carries no agent/model settings of its own — for custom nodes, no `cfg.agentId` and no `cfg.modelProvider`+`cfg.modelId` pair; for coding seams, no `task.assignedAgentId` and no `task.modelProvider`+`task.modelId` pair. Granularity is all-or-nothing: any own agent identity or complete model pair suppresses the column agent entirely.
+- R3. Override: the column agent supersedes node-level and task-level agent/model settings — identity, model, and persona.
+- R4. The binding keys off the node's **declared** IR column (`node.column`), never the task's current board lane. Foreach template nodes inherit the enclosing foreach node's column unless they declare their own. A node with no declared column resolves normally (no column agent), even in override mode.
+
+**Principal semantics**
+
+- R5. Under an effective column agent, action gating (`buildPermanentAgentGatingContext` / `buildActionGateContext`) is computed for the column agent — the agent actually running — not `task.assignedAgentId`.
+- R6. Heartbeat deferral (`shouldDeferForHeartbeat`) and resume (`resumeTaskForAgent`) honor the effective column agent: a column agent with `allowParallelExecution=false` is serialized the same way an assigned agent is. This includes `resumeTaskForAgent`'s task-selection query (it must re-dispatch tasks whose *effective* agent matches, not only `assignedAgentId` matches) and the heartbeat scheduler's reverse-direction guards keyed on `agent.taskId`.
+- R7. Column-agent-driven changes to the effective model/agent (workflow-definition edit, agent `runtimeConfig` change) hot-swap a running session with the same user-visible effect as a `task.modelProvider` change today, via save-event invalidation feeding the restart watcher (KTD-4). Agent deletion falls back without a restart storm.
+
+**Resilience & parity**
+
+- R8. A missing/deleted agent at resolution time logs and falls back to normal resolution (mirrors the existing best-effort posture at `packages/engine/src/executor.ts:4555`); a live session is never aborted because its column agent was deleted mid-flight.
+- R9. The built-in default workflow is untouched: the new IR field is omitted entirely when unset (never serialized as `agent: null` / explicit defaults), v2-only-feature detection registers it, and the existing parity suites stay green.
+- R10. Feature behavior requires both `experimentalFeatures.workflowColumns` and `experimentalFeatures.workflowGraphExecutor`; with either off, column agents are inert and the editor surfaces that.
+
+**Authoring surface**
+
+- R11. The workflow editor's column panel gets a per-column agent picker (registry-backed) plus a defer/override mode toggle; agent references are validated at write time with a clear error for unknown agents. Bound columns are visibly indicated, and a node inside an override column shows that its own executor settings are superseded — override must never look like a bug to the author.
+- R12. New IR types are re-exported type-only from `@fusion/plugin-sdk` (`WorkflowColumnAgent`; verify whether `WorkflowIrColumn`/`WorkflowIrColumnTrait` are already reachable through the existing core re-export block and add them only if absent).
+- R13. Binding an agent whose permission policy is broader than the project default requires explicit confirmation at save time — override cannot silently re-key action gates to a more-privileged agent.
+
+---
+
+## Key Technical Decisions
+
+- **KTD-1 — First-class optional field on `WorkflowIrColumn`, not a trait.** Traits are board-transition policy (flags + lifecycle hooks consumed by the move machinery); the agent binding is *execution identity* consumed by the executor's session-building paths. A typed `agent?: { agentId: string; mode: "defer" | "override" }` field gets schema validation, plugin-sdk type parity, and a purpose-built picker UI — a trait would bury it in an opaque `config: Record<string, unknown>` and overload the trait registry with a concept the transition machinery never reads. Follows the additive-optional-field precedent of `artifacts?`/`fields?` on `WorkflowIrV2`.
+
+- **KTD-2 — One shared resolver in `@fusion/core`; defer/override are explicit named rules, never a `??` collapse.** A single `resolveColumnAgentBinding(ir, nodeId)` (declared-column lookup + foreach template inheritance) and an effective-agent precedence function live in core and are consumed by every reader — the three engine resolution sites and the dashboard write-validation route. Two institutional learnings drive this: the per-task auto-merge override died because the override was honored at the action site but not at the 20+ trigger-layer gates (`docs/solutions/logic-errors/per-task-auto-merge-override-ignored-by-trigger-gates.md`), and route-vs-engine predicate duplication drifted into a data-loss hazard (`docs/solutions/integration-issues/branch-group-single-pr-synthetic-id-dead-wiring.md`).
+
+- **KTD-3 — The effective column agent is the principal.** Several subsystems assume the running agent is `task.assignedAgentId` today: the restart watcher (`packages/engine/src/executor.ts:2060`), heartbeat deferral/resume (defined `:3031`/`:3056`; the deferral gate call is `:4723`, and `resumeTaskForAgent`'s task-selection query filters on `assignedAgentId`), the heartbeat scheduler's reverse-direction guards keyed on `agent.taskId` (`packages/engine/src/agent-heartbeat.ts`), and permanent-agent action gating (`:1515`, `:1581`). Under override, the agent actually running differs from `assignedAgentId` — computing permission gates for the wrong principal is a security boundary error, and bypassing `allowParallelExecution=false` violates the agent's own contract. All of these must consult the effective agent. The gating-context builders already accept an `Agent` object parameter (callers resolve and pass it in), so principal substitution there is a call-site object swap, not gating-internals surgery — the real risk is resolving the right agent per session and closing the resume/heartbeat reverse-mapping gaps (U5).
+
+- **KTD-4 — Mid-flight edits hot-swap via save-event invalidation; no new edit guard.** The existing restart watcher diffs cached *task* fields — a workflow-definition edit or agent `runtimeConfig` change mutates nothing it observes, so "just feed the diff" is not a mechanism that exists. The primary mechanism is event-driven invalidation: workflow-definition saves and agent-config updates re-resolve the column-effective provider/model/agent into the watcher's tracked state, which then triggers the same restart path a `task.modelProvider` change does today. (Per-tick IR re-resolution is the fallback only if event hooks prove insufficient — it is hot-path-expensive, not the default.) The invalidation hook distinguishes agent-deleted (fall back per R8, no restart) from agent-changed (restart). We deliberately do not mirror `packages/core/src/node-override-guard.ts` (which blocks node-override edits while in-progress): hot-swap is the established posture for model/agent changes, and blocking workflow saves because some card somewhere is in a bound column would make workflow editing unusably brittle. Pause of the effective agent routes through heartbeat deferral (R6).
+
+- **KTD-5 — Defer granularity is all-or-nothing.** "Own settings" means an own agent identity OR a complete `modelProvider`+`modelId` pair; either suppresses column defer entirely. An incomplete model pair with no agent identity does not count (the existing resolver already ignores incomplete pairs — `resolveExecutorSessionModel`'s both-present semantics, `packages/engine/src/agent-session-helpers.ts:147-150`). The column agent is never blended with own settings: filling "only the missing half" would create hybrid identities (column agent's model with the task agent's persona) that are impossible to reason about in audit.
+
+- **KTD-6 — Persona injection follows the coding-session path, and reconciles the field drift.** The custom-node `"agent"` branch reads `agent.customInstructions` (`packages/engine/src/executor.ts:4553`) while the `Agent` type exposes `soul`/`instructionsText` (`packages/core/src/types.ts:5955-5957`) and the coding session resolves persona via `resolveInstructionsForRole` + `buildPromptLayers` (`executor.ts:5800-5840`). The column-agent path uses the typed fields consistently in both places; U3 fixes the custom-node branch to read the same fields rather than perpetuating the drift.
+
+- **KTD-7 — No store schema bump.** The binding lives inside the JSON-serialized workflow IR (parsed by `parseWorkflowIr`); workflow definitions are stored as blobs, so no `SCHEMA_VERSION` change is needed. Write-time validation happens in the dashboard route; read-time misses degrade gracefully (R8).

+## High-Level Technical Design

+
+## Implementation Units
+
+### U1. IR schema, validation, and parity registration
+
+**Goal:** `WorkflowIrColumn` gains an optional, additively-validated `agent` binding that never perturbs legacy or default workflows.
+
+**Requirements:** R1, R9, R12
+
+**Dependencies:** none
+
+**Files:**
+- `packages/core/src/workflow-ir-types.ts` — `WorkflowColumnAgent` interface; `agent?: WorkflowColumnAgent` on `WorkflowIrColumn`
+- `packages/core/src/workflow-ir.ts` — extend `validateColumns` (`:729`); register in v2-only-feature detection (`:858-878`); ensure serialization omits the field when unset
+- `packages/plugin-sdk/src/index.ts` — type-only re-export `WorkflowColumnAgent`; check whether `WorkflowIrColumn`/`WorkflowIrColumnTrait` are already reachable through the existing `@fusion/core` re-export block and add them only if absent (R12)
+- `packages/core/src/__tests__/workflow-ir-column-agent.test.ts` (new)
+
+**Approach:** Mirror the `validateFields` pattern (`workflow-ir.ts:660` — early return when absent). Validation when present: `agentId` non-empty string, `mode` one of `defer`/`override`. Additionally validate that every `node.column` reference — **including nodes inside foreach `template` subgraphs** — resolves to a declared column id, so a template node with a dangling column is a typed validation error rather than a silent no-binding no-op at runtime. Agent *existence* is not an IR-validation concern (the IR layer has no agent store) — that's write-time route validation (U6) and read-time fallback (U3/U4).
+
+**Patterns to follow:** `artifacts?`/`fields?` additive-optional precedent on `WorkflowIrV2`; `validateFields` early-return validator shape.
+
+**Test scenarios:**
+- Column with `agent: { agentId: "agent-001", mode: "defer" }` parses and round-trips; field absent → parses identically to today.
+- `agent` with empty `agentId`, missing `mode`, or unknown `mode` value → typed validation error naming the column id.
+- v1 graph upgrade via `synthesizeDefaultColumns` produces columns with no `agent` field (absent, not null).
+- Template-subgraph node with a `column` value matching no declared column id → typed validation error naming the node.
+- Default workflow IR (`builtin-coding-workflow-ir.ts`) round-trips byte-identically; v2-only-feature detection flags a graph with a column agent as non-default.
+- Serialization of a column whose binding was removed omits the key entirely.
+
+**Verification:** core IR tests green; existing `workflow-ir.test.ts`, `migration-workflow-columns.test.ts`, and the cli `plugin-sdk-export` test untouched-green.
+
+---
+
+### U2. Core effective-agent resolver
+
+**Goal:** A single `@fusion/core` module owns "which agent does this node's work" — binding lookup and the two named precedence rules — so engine and dashboard can never drift.
+
+**Requirements:** R2, R3, R4
+
+**Dependencies:** U1
+
+**Files:**
+- `packages/core/src/column-agent-resolver.ts` (new)
+- `packages/core/src/index.ts` — export
+- `packages/engine/src/workflow-graph-foreach.ts` — re-point `instanceNodeId` import to core (format ownership moves)
+- `packages/core/src/__tests__/column-agent-resolver.test.ts` (new)
+
+**Approach:** Two pure functions. `resolveColumnAgentBinding(ir, nodeId)` resolves the node's `column` against `ir.columns` and returns the binding or undefined (a column without an `agent` field yields no binding — that, not "column undeclared," is the operative guarantee, since v1→v2 upgrade synthesizes a column for every node); for foreach instance node ids (`<foreachId>#<i>:<templateNodeId>`) it resolves the *enclosing foreach node's* column, honoring a template node's own declared column when present. The instance-id format currently lives engine-side (`workflow-graph-foreach.ts` `instanceNodeId`): move `instanceNodeId` plus a paired `parseInstanceNodeId` into `@fusion/core` and re-point the engine import, so the format has exactly one owner (the route/engine predicate-drift learning). Parse defensively — split on the first `#`, then the first `:`, since `templateNodeId` is not sanitized against containing `:`. `resolveEffectiveAgent({ binding, ownAgentId, ownModelPair })` implements R2/R3 as explicit branches (per the auto-merge-override learning: distinct named rules, no effective-value `??` collapse) and returns a discriminated result (`column-agent` | `own-settings` | `none`) so callers and audit logs can state *why* an agent was chosen.
+
+**Test scenarios:**
+- Override × own settings present → column agent. Override × no own settings → column agent.
+- Defer × own agentId only → own settings win. Defer × complete own model pair only → own settings win. Defer × lone provider with no modelId and no agentId → column agent wins (an incomplete pair does not count as own settings, matching `resolveExecutorSessionModel`'s both-present rule, KTD-5). Pin all three explicitly.
+- No `node.column` → no binding, even when other columns carry override agents.
+- Foreach instance id resolves to the foreach node's column; template node with its own `column` wins over inheritance.
+- Two tasks differing only in column binding diverge (the divergence-assertion pattern from the auto-merge learning).
+
+**Verification:** resolver tests enumerate the full mode × own-settings matrix; no engine import in the module (core stays DI-clean).
+
+---
+
+### U3. Custom-node resolution honors the column binding
+
+**Goal:** Prompt/gate/script/skill nodes in a bound column run as the column agent per mode.
+
+**Requirements:** R2, R3, R4, R8
+
+**Dependencies:** U2
+
+**Files:**
+- `packages/engine/src/executor.ts` — `runGraphCustomNode` (`:4498-4644`)
+- `packages/engine/src/__tests__/executor-column-agent-custom-node.test.ts` (new)
+
+**Approach:** The IR is *not* in scope inside `runGraphCustomNode` — resolve the column binding in the `runCustomNode` seam wiring (`executor.ts:3327`, where the graph runner's callbacks are constructed and the resolved IR is available) and pass the binding into `runGraphCustomNode` as a parameter; if resolution must happen inside instead, use `resolveWorkflowIrForTask` with the `hold-release.ts` irCache pattern — never an uncached per-node store fetch. On `column-agent`: fetch via `agentStore.getAgent` (best-effort, log + fall back on null — same posture as `:4555`), adopt `runtimeConfig.executorProvider/executorModelId` and persona, and emit a `logEntry` naming the substitution and mode (e.g., "running as column agent X (override)") so the audit trail explains who ran and why — mirroring the `:4556` fallback-log pattern. Override replaces the node's own `agentId`/model/persona wholesale; defer fires only when the resolver said so. Persona uses the typed `soul`/`instructionsText` fields and this unit fixes the existing `customInstructions` drift (KTD-6). `executorKind: "cli"`/`"skill"` nodes keep their execution mechanics; the column agent contributes model/persona where a session runs (skill prompt sessions), and is a no-op for raw CLI script execution — log the skip so audit explains it.
+
+**Patterns to follow:** the existing `"agent"` branch at `executor.ts:4546-4560` (model adoption + persona prepend + best-effort fallback).
+
+**Test scenarios:**
+- Override column: node with its own `cfg.agentId` runs as the column agent (model + persona from column agent asserted on the synthesized `WorkflowStep`), and the task log records the substitution and mode.
+- Defer column: node with own `cfg.agentId` keeps it; bare node adopts the column agent.
+- Missing column agent in registry → logged, node falls back to its own/default resolution, node still executes.
+- Node with no declared column in a graph that has bound columns → untouched resolution.
+- CLI-executor node in an override column → mechanics unchanged, audit log notes the skip.
+
+**Verification:** new tests green; existing `workflow-graph-executor-handlers.test.ts` and `workflow-node-handlers.test.ts` untouched-green.
+
+---
+
+### U4. Coding seams: execute + step-execute sessions
+
+**Goal:** The main coding session and per-step sessions run as the column agent when the seam node's column is bound — the "does whatever work for that column's steps" half.
+
+**Requirements:** R2, R3, R4, R8
+
+**Dependencies:** U2
+
+**Files:**
+- `packages/engine/src/executor.ts` — execute-seam session build (`:5649-5767`), step-session branch (`:5154-5183`), graph seam wiring (`:4203-4223`)
+- `packages/engine/src/step-session-executor.ts` — model/agent resolution (`:985-1021`)
+- `packages/engine/src/agent-session-helpers.ts` — only if the effective-agent input needs threading into `resolveExecutorSessionModel` callers
+- `packages/engine/src/__tests__/executor-column-agent-seams.test.ts` (new)
+
+**Approach:** At the graph seams the executor knows the seam node and the resolved IR. Resolve the effective agent once per seam invocation; when it yields `column-agent`, substitute that agent where `assignedAgentId`'s agent flows today — `resolveExecutorSessionModel`'s `assignedAgentRuntimeConfig` argument, `extractRuntimeHint`, persona via `resolveInstructionsForRole`/`buildPromptLayers`, memory tools, and the session's `agentId` attribution in `StepSessionExecutor`. Adoption is audited via `logEntry` at the seam (same contract and wording shape as U3). Defer mode maps onto the resolver verdict computed from `task.assignedAgentId` + `task.modelProvider/modelId`. Foreach instances inherit the foreach node's column (resolver handles id parsing, U2). Flag-OFF and legacy (non-graph) execution never reach this code path — the legacy executor doesn't read `node.column` at all, preserving R10 structurally.
+
+**Execution note:** characterization-first — pin the current `assignedAgentId` session-identity behavior for both seams before introducing the substitution, so the no-binding path is provably byte-identical.
+
+**Test scenarios:**
+- Execute seam, override column, task with `assignedAgentId` Y → session built with column agent X's model/persona/identity; audit shows the `column-agent` reason.
+- Execute seam, defer column, task with complete `modelProvider/modelId` → task settings win.
+- Step sessions: foreach template `step-execute` node inherits the foreach node's bound column; each instance session carries the column agent's identity (`agentId` attribution asserted).
+- No binding anywhere → session construction byte-identical to the pinned characterization (parity).
+- Column agent missing from registry at seam time → fallback to `assignedAgentId` path, logged, run proceeds.
+- Integration scenario (per the plugin-skills learning — prove with a real resolver, not a scripted session): a real session-build path carries the column agent's `executorProvider/executorModelId` end-to-end into `createResolvedAgentSession` options.
+
+**Verification:** new seam tests green; `step-session-executor.test.ts`, `agent-session-helpers.test.ts`, and `workflow-graph-executor-parity.test.ts` untouched-green.
+
+---
+
+### U5. Principal alignment: gating, heartbeat deferral, restart watcher
+
+**Goal:** The three subsystems that assume "the running agent is `task.assignedAgentId`" consult the effective column agent instead, closing the security and serialization gaps.
+
+**Requirements:** R5, R6, R7
+
+**Dependencies:** U4
+
+**Files:**
+- `packages/engine/src/executor.ts` — restart watcher (`:2060-2090`), `shouldDeferForHeartbeat` (defined `:3031`; the deferral gate call site that must consult the effective principal is `:4723`), `resumeTaskForAgent` (defined `:3056` — both its gate input AND its task-selection query change), gating-context builders (`:1515`, `:1581`)
+- `packages/engine/src/agent-heartbeat.ts` — reverse-direction `agent.taskId` parallel-execution guards
+- `packages/engine/src/__tests__/executor-column-agent-principal.test.ts` (new)
+
+**Approach:** Introduce `resolveEffectivePrincipal(task, resolvedBinding)` — **session-scoped**, receiving the binding already computed by the U2 resolver for the specific governing node (not a task-wide lookup), returning the principal (column agent when the binding governs, else `assignedAgentId`). Feed it to: (a) `buildPermanentAgentGatingContext`/`buildActionGateContext` — both already accept an `Agent` object, so this is a call-site object swap at the session-build sites; (b) heartbeat serialization in **both directions**: the deferral gate at `:4723` consults the effective principal, `resumeTaskForAgent`'s task-selection query gains a second pass that re-dispatches tasks whose effective column agent matches (after the existing `assignedAgentId` filter), and the heartbeat scheduler's `agent.taskId`-keyed guards in `agent-heartbeat.ts` learn that an agent may be effectively executing column-bound tasks it is not assigned to — otherwise an `allowParallelExecution=false` column agent heartbeats concurrently with its own override session; (c) the restart watcher via save-event invalidation (KTD-4): workflow-definition saves and agent-config updates re-resolve the column-effective provider/model/agent into the watcher's tracked state, distinguishing agent-deleted (fall back per R8, no restart) from agent-changed (restart). Per-node resolution means a task may have >1 effective agent across concurrent split-branch sessions — deferral/gating evaluate per session, not per task.
+
+**Test scenarios:**
+- Override column, task assigned to Y, column agent X with `allowParallelExecution=false` and an active heartbeat run → execute defers; `resumeTaskForAgent(X)` re-dispatches it via the effective-agent pass (the `assignedAgentId` filter alone would miss it — assert the second pass fires).
+- Reverse direction: agent X (`allowParallelExecution=false`) is executing an override-column task it is not assigned to → X's heartbeat timer does not fire concurrently.
+- Action gating context built for X (not Y) when the column binding governs; built for Y when no binding.
+- Workflow edit changes the column's agent while a session runs → restart watcher fires (mirrors the existing model-change restart assertion shape at `executor.ts:2062-2075` tests).
+- Column agent deleted mid-session → no restart-storm, session finishes, next resolution falls back (R8).
+- Split branches with different bound columns → two sessions, two principals, each gated independently.
+
+**Verification:** principal tests green; no regression in existing heartbeat/gating suites (`agent-*` engine tests).
+
+---
+
+### U6. Dashboard: column agent picker, mode toggle, write-time validation
+
+**Goal:** Workflow authors staff a column from the editor; invalid agent references are rejected at save.
+
+**Requirements:** R10, R11
+
+**Dependencies:** U1
+
+**Files:**
+- `packages/dashboard/app/components/WorkflowColumnPanel.tsx` — agent picker + defer/override toggle per column, bound-column indicator
+- `packages/dashboard/app/components/WorkflowNodeEditor.tsx` — "overridden by column agent" note on nodes in override columns; stale-agentId treatment shared with the column picker
+- `packages/dashboard/src/routes/register-workflow-routes.ts` — extend the POST `/api/workflows` and PATCH `/api/workflows/:id` handlers: `assertColumnAgentsExist(ir, agentStore)` helper parallel to `assertCodeNodesCompile`, plus the policy-escalation confirmation (R13)
+- `packages/dashboard/src/__tests__/workflow-routes.test.ts` — extend
+- `packages/dashboard/src/routes/__tests__/board-workflows.test.ts` — extend if column payloads surface there
+
+**Approach:** Mirror the `fetchAgents()` dropdown pattern from `WorkflowNodeEditor.tsx:560-571, 800-803`, loading eagerly on panel mount. Picker renders "(none)" + registry agents; selecting one reveals the defer/override toggle (default `defer` — the less surprising mode). Interaction states are specified, not implementer-invented: **flags off** → disabled (not hidden) with a tooltip naming both required flags, matching the existing `readOnly` title-hint pattern (`WorkflowColumnPanel.tsx:113-115`); **fetch in flight** → picker disabled; **fetch failed** → inline error on the picker, not only a toast; **stored `agentId` absent from the registry** → render "Agent not found — \<id\>" warning instead of a blank select, preserving the IR until the author explicitly clears or replaces it (apply the same stale-id treatment to the node-level picker). **Override visibility (R11):** a bound column shows the agent name/badge on its header, and a node inside an override column shows an "overridden by column agent" note beside its own executor settings — without this, authors diagnose override as a bug. **Write-time validation (R13):** `assertColumnAgentsExist` returns a typed 4xx naming the column for unknown agents; when the bound agent's `permissionPolicy` is broader than the project default, the save requires an explicit `confirmPolicyEscalation` flag in the request body so override cannot silently re-key action gates to a more-privileged agent. Per the SWR-identity learning, key any selection/reset state on agent ids, not cached array identity.
+
+**Test scenarios:**
+- Save with valid `agent` binding persists and round-trips through the definition GET.
+- Save referencing an unknown `agentId` → typed 4xx naming the column; definition unchanged.
+- Save binding a more-privileged agent without `confirmPolicyEscalation` → typed 4xx naming the policy gap; with the flag → persists (R13).
+- Save with binding absent → stored IR has no `agent` key (omission asserted, R9).
+- Stored `agentId` missing from the registry response → picker renders the not-found warning with the stale id; IR untouched until explicitly cleared (component-level).
+- Node inside an override column renders the overridden-by-column-agent note (component-level).
+- Flags off → picker disabled with the flag-naming hint (component-level), and the route still accepts/round-trips bindings (config is data; execution is what's gated).
+
+**Verification:** dashboard route tests green; manual editor check via the worktree-safe dashboard flow (`docs/solutions/` browser-testing note) if UI verification is wanted.
+
+---
+
+### U7. Surface-enumeration test matrix, parity proof, changeset, docs
+
+**Goal:** Prove the invariant across every surface and both modes; document the feature.
+
+**Requirements:** R9, plus cross-cutting assertions for R1-R8
+
+**Dependencies:** U3, U4, U5, U6
+
+**Files:**
+- `packages/engine/src/__tests__/workflow-graph-executor-parity.test.ts` — extend: default workflow with no bindings is byte-identical
+- new matrix coverage distributed into the U3/U4/U5 test files (this unit audits completeness rather than duplicating)
+- `.changeset/*.md` — minor, `@runfusion/fusion`
+- docs: workflow-authoring docs section covering column agents, defer/override semantics, and the foreach inheritance rule
+
+**Approach:** Per FN-5893 surface enumeration, the matrix is mode (`defer`/`override`) × surface (custom node, execute seam, step-execute, heartbeat-deferred, missing-agent fallback) × own-settings (present/absent). Most cells land in U3-U5; this unit's job is the completeness audit, the parity extension, and the explicit two-tasks-differing-only-in-binding divergence test if not already present.
+
+**Test scenarios:**
+- Matrix audit: every mode × surface × own-settings cell has an assertion somewhere (enumerate in a comment block or table in the parity test).
+- Default workflow parity: graph with zero bindings produces identical observations via `compareWorkflowRunObservations`.
+
+**Verification:** `pnpm test` (changed) green; `pnpm lint` and `pnpm build` green; changeset present.
+
+---
+
+## Scope Boundaries
+
+### Deferred to Follow-Up Work
+
+- **Legacy (non-graph) executor support** — column agents only act under `workflowGraphExecutor`; teaching the legacy fixed pipeline about column staffing is not planned (the legacy path is slated for post-graduation removal per the columns track).
+- **Per-column agent *pools*** (multiple agents per column with load-balancing) — single agent per column this round; the IR field shape (`agent?` object) leaves room to widen.
+- **Exclusive reservation semantics** — the binding is execution identity, not a scheduling reservation; the column agent can still do unrelated work. Capacity remains the `wip` trait + `AgentSemaphore`'s job.
+- **Plugin-authored column agents in manifests** — plugins get the types (R12) but no manifest contribution surface for column bindings this round.
+
+### Outside this product's identity
+
+- Human assignee semantics (columns "assigned" to people, approvals routing) — agents only; human gates remain the `human-review` trait's territory.
+
+---
+
+## Risks & Dependencies
+
+- **Step-inversion track is active on this branch.** U4 touches the same seam code (`step-execute`, `StepSessionExecutor`) that track is building. Sequence this plan's U4 after the step-inversion units that establish `runTaskStep` land, or coordinate in the same PR series — implementer should check branch state at execution time.
+- **Principal substitution (U5) is the highest-risk unit** — it alters permission-gating identity. The characterization-first posture in U4 plus the no-binding byte-identical assertions are the guardrails; any ambiguity during implementation should resolve toward "gate as the agent actually running."
+- **Restart-watcher integration** is event-driven (KTD-4): workflow-definition saves and agent-config updates are the invalidation triggers. If an event path proves unreliable, per-tick IR re-resolution is the (hot-path-expensive) fallback — a contained implementation decision inside U5. Note the weaker guarantee either way: a stale session restarts on the *event*, not on an arbitrary-time diff.

+- Graph executor never reads `node.column` today (confirmed by sweep) — the binding lookup is net-new plumbing at the seams, not a change to walk routing.

+/**
+ * Claude Code adapter — the reference native-tier CliAgentAdapter (U4).
+ *
+ * Claude Code exposes the richest native telemetry of the four launch agents:
+ * a full hook roster (`SessionStart`, `PreToolUse`/`PostToolUse`,
+ * `UserPromptSubmit`, `Notification`, `PermissionRequest`, `Stop`) that each
+ * deliver a JSON payload (`hook_event_name`, `session_id`, `transcript_path`,
+ * `source`, `notification_type`, …) on the hook command's stdin, plus a JSONL
+ * transcript on disk. This adapter teaches the engine to:
+ *   - launch `claude` with a SESSION-SCOPED additional settings file that
+ *     registers those hooks pointing at this session's hook script (so we never
+ *     touch the user's global `~/.claude` or the repo's tracked `.claude/`);
+ *   - normalize raw hook payloads → engine `TelemetryEvent`s;
+ *   - tail the JSONL transcript incrementally for chat;
+ *   - resume via `claude --resume <session-id>`.
+ *
+ * ── Verified against the installed binary (Claude Code 2.1.165, arm64) ──
+ * The following were confirmed by probing the shipped binary, not assumed:
+ *   - CLI flags: `--settings <file-or-json>` (additional settings), `--resume`
+ *     / `-r [value]` (resume by session id), `--session-id <uuid>`,
+ *     `--setting-sources`, `-p/--print` (non-interactive).  [`claude --help`]
+ *   - Hook event names present in the binary: `SessionStart`, `PreToolUse`,
+ *     `PostToolUse`, `UserPromptSubmit`, `Notification`, `PermissionRequest`,
+ *     `Stop`, `SubagentStop`, `PreCompact`, `SessionEnd`.
+ *   - Payload field names present: `hook_event_name`, `session_id`,
+ *     `transcript_path`, `notification_type`, plus notification kinds
+ *     `permission_prompt` / `idle_prompt`, and SessionStart `source` enum
+ *     values `startup` / `resume` / `clear` / `compact`.
+ *   - Settings hook schema shape (from the binary's embedded docs):
+ *       { "hooks": { "<EventName>": [ { "matcher": "...",
+ *           "hooks": [ { "type": "command", "command": "<script>" } ] } ] } }
+ *     The hook command receives the event payload as JSON on stdin.
+ *
+ * ── Assumed (marked so wiring composes; revisit if a version drifts) ──
+ *   - The session-scoped hook SCRIPT itself is produced by the U17 hook-scripts
+ *     module. That module does not exist in this worktree yet, so this adapter
+ *     accepts the already-written script paths via `HookScriptRefs` on the
+ *     launch settings (see `claudeCodeSettings`). The adapter only emits the
+ *     settings JSON that references them.
+ *   - `Stop` carries no machine-readable success/failure flag in the payload we
+ *     can rely on across versions; we map `Stop` → `done` (positive completion)
+ *     and expose `classifyStop` so a caller can downgrade to an error-ish event
+ *     when it has out-of-band failure evidence (e.g. `stop_reason`).

+
+Add the generic heuristic-tier CLI agent adapter (U6).
+
+Arbitrary user-configured CLI commands can now run as engine-owned PTY sessions. The generic adapter declares every native capability disabled (no native done/waiting signal, no transcript) and infers state purely from the terminal byte stream: busy while output progresses or a spinner animates, and a synthetic idle after a configurable quiet window when a prompt-like glyph is showing and no spinner overrides it. Per the completion-gating decision (origin R20) the generic tier NEVER reports done — idle surfaces a "looks idle — confirm to advance" affordance via a new busy-equivalent idle sub-state and never advances the pipeline.

+/**
+ * GenericCliAdapter — heuristic-tier adapter for arbitrary CLI commands
+ * (CLI Agent Executor, U6).
+ *
+ * The generic adapter drives ANY user-configured CLI command inside an
+ * engine-owned PTY when no native-tier adapter (Claude Code / Codex / Droid /
+ * Pi) applies. It has NO native completion signal, NO native waiting signal, and
+ * NO structured transcript — every capability flag is disabled and its
+ * transcript source is `"none"`. Surfaces render the honest heuristic tier from
+ * these flags (origin R3, AE4).
+ *
+ * Because the command is opaque, state is inferred purely from the terminal byte
+ * stream by {@link GenericHeuristicAnalyzer}:
+ * - BUSY when output is progressing OR a spinner is animating (braille spinner
+ *   glyphs, `/-\|` rotation, "Working"/"Thinking" tickers, an elapsed-time
+ *   counter).
+ * - IDLE after a configurable quiet window (default ~8s) of no output AND a
+ *   prompt-like trailing glyph (`>`, `❯`, `$`, `:`, `?`, …) AND no active
+ *   spinner override.
+ *
+ * Completion gating (origin R20, KTD — the generic tier NEVER reports done):
+ * idle is emitted as the telemetry `"idle"` kind, which the state machine maps
+ * to a busy-equivalent idle sub-state surfacing a "looks idle — confirm to
+ * advance" affordance. It NEVER advances to `done`. Resumed output flips back to
+ * busy. The only positive completion path is operator confirmation downstream.
+ *
+ * No resume (`supportsResume: false`) — a fresh launch only; the lack of resume
+ * is surfaced honestly in the UI (U8 routes generic sessions to needs-attention
+ * on engine death rather than auto-resuming).

Subject: [PATCH 038/112] feat(core): column agent IR schema, validation, and
 effective-agent resolver

U1+U2 of the column-agent plan: WorkflowColumnAgent on WorkflowIrColumn
(defer/override), template-subgraph column validation, v2-only-feature
registration, plugin-sdk type parity, and the shared core resolver with
instanceNodeId format ownership moved to core.

+
+Add the CLI Agent Executor hook ingestion route and per-session hook scripts
+(U17). The dashboard now serves a localhost-only `POST /api/cli-agent/hooks`
+endpoint that authenticates per-session hook POSTs from a spawned CLI agent and
+forwards the validated payload in-process to the engine telemetry hub (the engine
+has no HTTP server — only the dashboard serves HTTP).
+
+The route is hardened because localhost is not a trust boundary: it validates the
+high-entropy per-session token against the engine-held registry (a session id
+alone is never sufficient, and a token for one session never validates for
+another), rejects browser-context requests via Origin/Host CSRF checks, caps the
+payload size, and treats an unknown/non-live session as a 200 no-op rather than a
+crash. It is exempt from the daemon bearer-token middleware (hook scripts only
+hold the per-session token) but authenticates with that token instead.
+
+The engine gains `hook-scripts.ts`: it generates the per-session hook script and
+notify shim (Orca `agent-hooks` shape — `curl` POST of the stdin JSON with the
+session token header, short timeouts, always exit 0), writes them into a
+session-scoped config dir (owner-only, executable), and deletes that dir on
+session end (the token is registry-invalidated at the same moment, bounding its
+at-rest exposure to the session lifetime).

+/**
+ * CLI-agent hook ingestion route (CLI Agent Executor, U17).
+ *
+ * A localhost POST endpoint that authenticates per-session hook POSTs from a
+ * spawned CLI agent (Claude Code, Codex, Droid, …) and forwards the validated,
+ * parsed payload IN-PROCESS to the engine-held telemetry hub. The engine has no
+ * HTTP server — only the dashboard serves HTTP (the Orca pattern, adapted).
+ *
+ * Security posture (KTD — hook-endpoint security; localhost is NOT a trust
+ * boundary: any local process or browser page can reach 127.0.0.1):
+ *
+ * 1. Per-session token, constant-time. The request must carry the high-entropy
+ *    per-session hook token AND the session id; the route validates that the
+ *    token was issued for exactly that session against the engine-held registry
+ *    (`hub.validateToken`). A session id alone is NEVER sufficient, and a valid
+ *    token for session B never validates for session A. Comparison is
+ *    constant-time inside the hub registry lookup; the header presence check here
+ *    avoids leaking timing on the cheap path only.
+ *
+ * 2. Origin / Host CSRF defense. A browser page on any origin can POST to
+ *    127.0.0.1, so a forged `Stop`/completion could otherwise advance incomplete
+ *    work or suppress the stall detector. We REJECT any request carrying a
+ *    browser `Origin` header, and any request whose `Host` is not a loopback
+ *    host. Hook scripts are plain `curl` (no Origin); browsers always attach one
+ *    on cross-origin fetch — so this cleanly separates the two.
+ *
+ * 3. Payload cap. Oversized bodies are rejected (413) — both at parse time (a
+ *    route-scoped `express.json` limit) and defensively via `Content-Length`.
+ *
+ * 4. No daemon bearer token. Hook scripts only hold the per-session token, so
+ *    this path is EXEMPT from the daemon-token middleware (see auth-middleware
+ *    `EXEMPT_PATHS`). It is not unauthenticated — it authenticates with the
+ *    per-session token instead.
+ *
+ * 5. Never crash. An unknown / non-live session key is a 200 no-op (the hub's
+ *    `ingest` is itself a no-op for unknown sessions); malformed JSON is a 400;
+ *    nothing here throws into the agent's hook chain.

+ *   registry-invalidated at the same moment (`hub.invalidate`).
+ * - The script NEVER sets an `Origin` header — the route rejects browser-context
+ *   requests (Origin/Host CSRF defense). A plain `curl` POST has no Origin.

+ *   slow / down / wedged endpoint can never block or fail the agent's own hook
+ *   chain (telemetry is best-effort; it must not gate the CLI).
+ *
+ * This module is pure engine code: it only generates script text and writes /
+ * removes files. It performs no networking and never mutates the user's global
+ * agent config (`~/.claude`, etc.) — only the session-scoped dir it is handed.

+/**
+ * cli-session-output-filter — outbound terminal-output hardening
+ * (CLI Agent Executor, U10).
+ *
+ * The CLI agent's terminal byte stream is UNTRUSTED: the agent (or anything it
+ * runs) controls the bytes, and a co-driving surface (browser xterm, TUI host
+ * TTY) honors escape sequences. Some sequences let an attacker exfiltrate or
+ * forge input, so the server-side WS bridge neutralizes them BEFORE forwarding
+ * a data frame. `neutralizeTerminalOutput` is the single, pure, streaming-safe
+ * implementation; the TUI (U14) re-imports it so every passthrough applies the
+ * identical set.
+ *
+ * The neutralized set (KTD — output hardening):
+ * - OSC 52 (clipboard write): `ESC ] 52 ; … BEL|ST` — a remote write to the
+ *   user's clipboard. Stripped entirely.
+ * - OSC 8 hyperlinks with a non-http/https scheme (e.g. `javascript:`,
+ *   `file:`): `ESC ] 8 ; params ; URI BEL|ST`. The URI is stripped (replaced
+ *   with an empty URI so the hyperlink is closed/neutral) while the visible
+ *   link TEXT that follows is kept. http/https links pass through untouched.
+ * - Device-status / query sequences whose auto-responses would forge INPUT back
+ *   into the PTY: DSR (`ESC [ … n`), DA1/DA2 (`ESC [ c`, `ESC [ > c`), and
+ *   DECRQSS (`ESC P $ q … ESC \`). A terminal answers these by writing bytes to
+ *   stdin — which converge on the agent's input FIFO — so a malicious stream
+ *   could smuggle keystrokes. Stripped.
+ *
+ * Streaming-safe: a sequence may be split across two chunks. The function takes
+ * (and returns) a small carry buffer holding a trailing partial sequence; the
+ * caller threads the carry across calls. `flush` emits any residual carry on
+ * stream end. The carry is bounded so a never-terminated sequence can't grow
+ * without limit.

+/**
+ * cli-session-ws — distinct WebSocket attach handler for CLI agent sessions
+ * (CLI Agent Executor, U10).
+ *
+ * This is a SEPARATE connection handler from the existing terminal WS
+ * (`/api/terminal/ws`): it shares only the upgrade gate shape (daemon-token
+ * auth) and the JSON frame protocol style. The connection body resolves the
+ * session from the engine's `CliSessionManager` (the explicit async attach
+ * interface), never the dashboard-local terminal service.
+ *
+ * Path: /api/cli-sessions/ws?sessionId=<id>&ticket=<ticket>[&fn_token=<token>]
+ *
+ * Upgrade gate (stronger than the terminal WS — this channel injects keystrokes
+ * into privileged agent PTYs):
+ *  1. daemon-token auth (authenticateUpgradeRequest), AND
+ *  2. an Origin allowlist check (reject foreign/absent browser Origin), AND
+ *  3. a valid, unconsumed, single-use ticket bound to this exact session.
+ *
+ * Frame protocol (JSON, mirrors the terminal WS shape):
+ *  server→client: {type:"scrollback", data}  (base64 bytes) — once, on connect
+ *                 {type:"data", data}         (base64 bytes) — live, neutralized
+ *                 {type:"state", ...}         (optional state hints)
+ *                 {type:"error", message}     (e.g. read-only input rejected)
+ *  client→server: {type:"input", data}        (utf8 keystrokes → PTY write)
+ *                 {type:"resize", cols, rows}  (latest-active-client resize)
+ *                 {type:"ack", bytes}          (ACK-credit flow control)
+ *
+ * Flow control: the client ACKs bytes it has consumed; the server tracks
+ * outstanding unacked bytes and, above the high watermark, calls
+ * `manager.requestPause`; back below the low watermark, `manager.requestResume`.
+ * The server never buffers PTY bytes — the engine owns the ring + pause/resume.
+ *
+ * Output hardening: every live `data` frame is passed through
+ * `neutralizeTerminalOutput` (carry threaded across chunks) BEFORE send.

Subject: [PATCH 043/112] feat(engine): custom workflow nodes run as their
 column's agent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

U3: per-run IR resolution feeds the core column-agent resolver at the
runCustomNode seam; override supersedes node agent/model/persona wholesale,
defer fills bare nodes only; adoption and fallback are audited via logEntry;
raw-CLI nodes log a skip. Also fixes the customInstructions persona drift —
node-level executor:"agent" persona injection now uses the typed
soul/instructionsText fields (KTD-6).

Subject: [PATCH 044/112] feat(dashboard): column agent picker, override
 visibility, write-time validation

U6: WorkflowColumnPanel agent picker + defer/override toggle with specified
interaction states (flags-off hint, loading, fetch-error, stale-agent
warning, bound-column badge); WorkflowNodeEditor overridden-by-column-agent
note + stale-id treatment; assertColumnAgentsExist + confirmPolicyEscalation
gate (R13) on workflow save routes; flowToIr now preserves column agent
bindings through the editor round-trip.

Subject: [PATCH 046/112] feat(cli): TUI full-screen attach to cli-agent
 sessions (U14)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Suspend-and-handoff passthrough from the Ink TUI to a cli-agent PTY session:
mint an attach ticket, open the cli-session WebSocket, enter the alternate
screen + raw mode, stream WS scrollback/data frames to stdout, frame stdin
bytes into input messages, propagate resizes, and ACK consumed bytes for flow
control. Detach chord Ctrl-] restores the terminal and remounts Ink; a dropped
WS surfaces the error and restores the terminal cleanly.

Untrusted terminal output is neutralized through the same hardening filter the
dashboard WS bridge uses (re-exported from @fusion/dashboard) so OSC 52, non-
http(s) OSC 8 links, and device-status queries are stripped before reaching the
host TTY — the riskiest leg, since the host terminal honors more sequences than
xterm.js. CJK/double-width bytes pass through verbatim.

- packages/cli/src/commands/dashboard-tui/terminal-attach.ts (passthrough loop +
  injectable WS transport for tests)
- controller.openTerminalAttach() Ink integration (unmount/run/remount)
- adds `ws` runtime dep to packages/cli
- re-exports neutralizeTerminalOutput/flushTerminalOutput from @fusion/dashboard

+Add full-screen TUI attach to cli-agent sessions (U14). The Ink dashboard TUI
+can hand the terminal to a CLI agent session as a raw passthrough: it enters the
+alternate screen, streams WebSocket terminal bytes to stdout and stdin keystrokes
+back as input frames, propagates resizes, and ACKs consumed bytes for flow
+control. The detach chord (Ctrl-]) restores the TUI cleanly, and a dropped
+connection surfaces an error and restores the terminal. Untrusted terminal output
+is neutralized through the same hardening filter the dashboard WS bridge uses
+(OSC 52 clipboard writes, non-http(s) OSC 8 links, and device-status queries are
+stripped before reaching the host TTY).

+/**
+ * terminal-attach — full-screen passthrough attach to a CLI agent session
+ * from the Ink TUI (CLI Agent Executor, U14).
+ *
+ * Model: SUSPEND-AND-HANDOFF, not embedding. The caller pauses Ink rendering,
+ * then `attachTerminalSession` takes over the real TTY:
+ *   - enter the alternate screen (`\x1b[?1049h`) and put stdin in raw mode,
+ *   - WS `scrollback`/`data` frames → neutralize (U10 filter) → write to stdout,
+ *   - stdin bytes → WS `input` frames (base64),
+ *   - SIGWINCH / stdout resize → WS `resize` frames,
+ *   - ACK `bytes` consumed after every ~32KB written, for flow control,
+ *   - detach chord Ctrl-] (0x1d) → leave alt-screen, restore raw mode, close WS,
+ *   - WS close/error mid-attach → restore the terminal cleanly + surface via
+ *     `onDetach(error)`.
+ *
+ * SECURITY (the riskiest leg): the byte stream is UNTRUSTED. The host terminal
+ * honors more escape sequences than xterm.js, so every byte written to the host
+ * TTY is passed through `neutralizeTerminalOutput` FIRST — the identical filter
+ * the dashboard WS bridge uses (re-exported from `@fusion/dashboard`). OSC 52
+ * clipboard writes, OSC 8 non-http(s) links, and device-status queries (whose
+ * auto-responses forge input) are stripped before they ever reach the terminal.
+ *
+ * CJK / double-width: bytes pass through verbatim — no width math is needed in a
+ * passthrough (the host terminal does the width handling).
+ *
+ * The WS transport is injectable (`wsFactory`) so tests drive the loop with an
+ * in-memory WS-like object and NEVER open a real socket (and never touch port
+ * 4040). The default factory uses the `ws` Node client.

Subject: [PATCH 047/112] feat(engine): add Codex, Droid, and Pi cli-agent
 adapters (U5)

Codex (hybrid tier): native done via session-scoped notify config,
heuristic PTY waiting detection, codex resume <thread-id>, probed rollout
JSONL tailer. Droid (native tier): Claude-style hooks with a Notification
permission-vs-idle classifier, --resume / exec -s resume (never -r in exec
mode). Pi (native tier): session-JSONL telemetry + transcript tailing,
pi --session resume. Adds the session-jsonl transcript source.

+---
+
+Add the Codex, Droid, and Pi CLI agent adapters (U5).
+
+Three new launch adapters join the engine's CLI agent executor, each declaring honest, verified capability flags so surfaces can render tier differences:
+
+- **Codex** (hybrid tier): native turn-complete via the session-scoped `notify` config program (`-c notify=[…]`), capturing `thread-id` as the native session id; waiting-on-input is inferred from ANSI-stripped PTY prompt-pattern heuristics (approval menus, idle composer markers, with a spinner/working override) because Codex has no native waiting signal; resume via `codex resume <thread-id>`; rollout JSONL transcript tailed by probing (not hardcoding) the sessions directory for the file matching the thread-id.
+- **Droid** (native tier): Claude-style hooks (`SessionStart`, `Stop`, `Notification`, tool-activity) delivering `session_id`/`transcript_path`/`permission_mode`; a message classifier splits the conflated `Notification` event into permission-request vs idle sub-reasons (both treated as waiting-on-input); resume via interactive `droid --resume <id>` or headless `droid exec -s <id>` — never the bare `-r` that means `--reasoning-effort` in exec mode.
+- **Pi** (native tier): telemetry and transcript from session-JSONL tailing under a session-scoped `--session-dir`; lifecycle events (turn/agent start→busy, end→done, input-request→waiting) plus message rows→transcript; resume via `pi --session <path|partial-uuid>`.
+
+A new `session-jsonl` transcript source is added to the adapter capability union for Pi.

+/**
+ * Codex adapter — HYBRID-tier CliAgentAdapter (U5).
+ *
+ * Codex is the hybrid tier: it has a NATIVE turn-complete signal (via its
+ * `notify` config program) and a structured rollout transcript on disk, but NO
+ * native waiting-on-input signal. Waiting-on-input is therefore inferred from
+ * the PTY byte stream with Codex-specific prompt-pattern heuristics (composed on
+ * top of the same ANSI-stripping the generic adapter uses). The capability flags
+ * advertise this honestly: `nativeDone: true`, `nativeWaiting: false`.
+ *
+ * This adapter teaches the engine to:
+ *   - launch `codex` with a SESSION-SCOPED notify program so a turn-complete
+ *     event reaches the engine without touching the user's `~/.codex/config.toml`
+ *     (mechanism below);
+ *   - normalize the notify JSON payload → a `done` `TelemetryEvent`, capturing
+ *     `thread-id` as the native session id;
+ *   - detect waiting-on-input via {@link CodexWaitingAnalyzer} (heuristic — see
+ *     the per-method docs; this is the hybrid-tier fallback, NOT a native signal);
+ *   - tail the rollout JSONL transcript incrementally (probing the sessions dir,
+ *     never hardcoding the layout — it is version-sensitive);
+ *   - resume via `codex resume <thread-id>`.
+ *
+ * ── Verified against the installed binary (Codex 0.128.0, arm64) ──
+ *   - `codex` is on PATH; `~/.codex/` is the default `CODEX_HOME`.
+ *   - Rollout JSONL layout CONFIRMED by inspecting real files:
+ *       `~/.codex/sessions/YYYY/MM/DD/rollout-<ts>-<thread-id>.jsonl`
+ *     with a first line `{type:"session_meta", payload:{ id:<thread-id>, cwd,
+ *     originator, cli_version, ... }}`, then `{type:"event_msg", payload:{
+ *     type:"task_started", turn_id, ... }}`, then `{type:"response_item",
+ *     payload:{ type:"message", role, content:[{type,text}] }}` lines. The
+ *     `thread-id` IS the `session_meta.payload.id` and is embedded in the
+ *     filename. We PROBE for the file by thread-id (see {@link findRolloutPath}),
+ *     never assuming the date path.
+ *   - `codex resume` and `codex exec` subcommands exist (`codex --help`); the
+ *     interactive `--help` for subcommands could not be captured in this sandbox
+ *     (the binary opens a TUI), so the exact resume arg shape below is per the
+ *     documented public interface: `codex resume <thread-id>` and the `-c
+ *     key=value` config-override flag.
+ *
+ * ── Assumed / mechanism choice (marked so wiring composes; revisit on drift) ──
+ *   - NOTIFY MECHANISM. Codex's documented native turn-complete is the `notify`
+ *     config key: `notify = ["<program>", ...args]`. Codex invokes that program
+ *     with a single JSON-string argument `{ type:"agent-turn-complete",
+ *     "thread-id":…, "turn-id":…, cwd:…, "last-assistant-message":… }`. Two
+ *     session-scoped delivery options exist; we choose **`-c notify=[...]`
+ *     config-override on the launch argv** as the PRIMARY mechanism (it is
+ *     session-scoped by construction and never mutates the user's config), and
+ *     expose a **layered `CODEX_HOME`** fallback for callers that prefer a
+ *     scratch config dir. See {@link buildNotifyOverrideArg} and
+ *     {@link codexSessionHomeLayout}. The notify PROGRAM itself (the shim that
+ *     forwards the payload to the engine telemetry hub) is produced by the U17
+ *     hook-scripts module; this adapter only references its path.
+ *   - The notify payload uses hyphenated keys (`thread-id`, `turn-id`,
+ *     `last-assistant-message`) per the documented schema; {@link mapNotifyPayload}
+ *     also tolerates the snake_case / camelCase variants in case a version drifts.

+/**
+ * Droid adapter — NATIVE-tier CliAgentAdapter (U5).
+ *
+ * Droid (Factory's CLI) exposes Claude-style hooks (`Stop`, `Notification`,
+ * `SessionStart`, `PreToolUse`/`PostToolUse`) that deliver a JSON payload
+ * carrying `session_id`, `transcript_path`, and `permission_mode`. Like Claude
+ * Code it is native tier — but with ONE caveat the KTD calls out: its
+ * `Notification` hook CONFLATES a permission request and a 60s-idle prompt into a
+ * single event whose only discriminator is a free-form `message` text field.
+ * This adapter implements a {@link classifyNotification} message classifier that
+ * tags the sub-reason while defaulting BOTH to `waitingOnInput` (both mean
+ * blocked-on-human).
+ *
+ * Capability flags advertise the native tier honestly: `nativeDone: true`,
+ * `nativeWaiting: true` (via parsing), `transcriptSource: "jsonl"`,
+ * `supportsResume: true`.
+ *
+ * Resume modes (the `-r` footgun):
+ *   - INTERACTIVE: `droid --resume <sessionId>` (`-r`/`--resume`).
+ *   - HEADLESS:    `droid exec -s <sessionId>` — `-s`/`--session-id`. In `exec`
+ *     mode `-r` means `--reasoning-effort`, NOT resume. {@link buildResume}
+ *     therefore NEVER emits a bare `-r` for resume in exec mode (asserted in the
+ *     tests). VERIFIED against the installed binary's `droid exec --help`.
+ *
+ * ── Verified against the installed binary (Factory Droid CLI) ──
+ *   - `droid` is on PATH (`~/.local/bin/droid`).
+ *   - `droid --help`: `-r, --resume [sessionId]`, `--settings <path>` ("Path to
+ *     runtime settings file merged for this process only" — the session-scoped
+ *     hook-config seam), `--cwd <path>`, `--fork <sessionId>`.
+ *   - `droid exec --help`: `-s, --session-id <id>` ("Existing session to
+ *     continue (requires a prompt)"), `-r, --reasoning-effort <level>`,
+ *     `-o, --output-format <format>`, `--auto <level>`,
+ *     `--skip-permissions-unsafe`. CONFIRMS the `-r` footgun.
+ *
+ * ── Assumed (marked so wiring composes; revisit on drift) ──
+ *   - HOOK CONFIG MECHANISM. Droid's `--settings <path>` merges a runtime
+ *     settings file for this process only — the session-scoped equivalent of
+ *     Claude's `--settings`. We assume it accepts a Claude-style `hooks` block
+ *     (event → [{ hooks:[{ type:"command", command }] }]); the binary's hooks
+ *     reference is documented as Claude-style. The hook SCRIPTS themselves come
+ *     from U17; this adapter only references their paths and emits the settings
+ *     JSON. If a Droid version diverges from the Claude hook schema this is the
+ *     one place to adjust ({@link buildDroidSettings}).
+ *   - The `Notification` payload's idle vs permission discriminator is the
+ *     `message` text; {@link classifyNotification} is the documented-gap
+ *     classifier.

+/**
+ * Pi adapter — NATIVE-tier CliAgentAdapter (U5).
+ *
+ * Pi (github.com/earendil-works/pi) is native tier: it writes a structured
+ * session JSONL to disk that we tail for telemetry AND transcript. Capability
+ * flags advertise this honestly: `nativeDone: true`, `nativeWaiting: true`,
+ * `transcriptSource: "session-jsonl"` (a JSONL transcript on disk), and
+ * `supportsResume: true`.
+ *
+ * This adapter teaches the engine to:
+ *   - launch `pi` with a SESSION-SCOPED `--session-dir <dir>` so the session file
+ *     is written somewhere discoverable (and never collides with the user's other
+ *     sessions);
+ *   - tail the session JSONL incrementally, mapping its event/message entries
+ *     onto normalized `TelemetryEvent`s and chat transcript entries;
+ *   - capture the native session id from the file's `session` header;
+ *   - resume via `pi --session <path|partial-uuid>`.
+ *
+ * ── Verified against the installed binary (Pi) ──
+ *   - `pi` is on PATH (`/opt/homebrew/bin/pi`).
+ *   - `pi --help`: `--session <path|id>` ("Use specific session file or partial
+ *     UUID"), `--session-dir <dir>` ("Directory for session storage and lookup"),
+ *     `--mode <mode>` ("Output mode: text (default), json, or rpc"),
+ *     `--resume, -r` (interactive picker), `--continue, -c`, `--no-session`,
+ *     `--print, -p` (non-interactive), `--fork <path|id>`.
+ *   - Session JSONL layout CONFIRMED by inspecting real files under
+ *     `~/.pi/agent/sessions/<cwd-encoded>/<ts>_<uuid>.jsonl`: a first line
+ *     `{type:"session", version, id:<uuid>, timestamp, cwd}`, then
+ *     `{type:"model_change"|"thinking_level_change", ...}` and
+ *     `{type:"message", id, parentId, timestamp, message:{ role, content:[
+ *     {type:"text"|"thinking", text|thinking} ] }}` rows. `role` is one of
+ *     `user` / `assistant` / `toolResult`.
+ *
+ * ── Assumed (marked so wiring composes; revisit on drift) ──
+ *   - TELEMETRY EVENT MAPPING. The KTD specifies turn_start/agent_start→busy,
+ *     turn_end/agent_end→done, input-request→waitingOnInput, message→transcript.
+ *     The recorded v3 sessions I inspected contained only `message` rows (no
+ *     explicit turn_* / agent_* / input-request rows — those arrive via the
+ *     event bus / `--mode json` in newer builds). {@link mapSessionLine}
+ *     therefore handles BOTH: explicit lifecycle events when present, AND a
+ *     message-shape fallback (assistant message → busy/transcript). The explicit
+ *     lifecycle event names are best-effort per the documented event bus and are
+ *     matched case-insensitively with several spellings.
+ *   - `--mode json` is an ALTERNATIVE interactive event stream; we implement the
+ *     deterministic JSONL tail instead (the file is the source of truth and
+ *     survives restarts). The session-dir mechanism makes the file discoverable.

Subject: [PATCH 048/112] feat(engine): wire cli-agent executor seam and task
 session lifecycle (U7)

Add `cli-agent` as a task-execute executor kind. A workflow node with
`config.executor === "cli-agent"` drives an engine-owned CLI coding agent
through the execute step via the new cli-agent/task-session.ts orchestration:
spawn in the worktree, issue the hook token + write hook scripts, inject the
prompt after readiness, subscribe to the state machine, and resolve on a
positive completion signal (R20 gating). Config is snapshotted at launch; the
PTY is reaped (completed) at the in-review handoff.

Executor seam: runGraphCustomNode gains a cli-agent branch delegating to
runCliAgentNode; the hard-cancel/abort path (awaitAbortInFlightTaskWork +
abortAllInFlight) claims and SIGKILLs the CLI session as a first-class surface,
marking it killed (never resume-eligible). Re-entry kills any prior live
session and launches fresh; follow-up resumes the recorded native session id
when supported. A PTY-pool ceiling surfaces as a typed task value, not a stall.

Node-config typing extended minimally (WorkflowNodeExecutorKind /
WorkflowNodeExecutorConfig in @fusion/core).

Tests: cli-agent/__tests__/task-session.test.ts (12) and
__tests__/cli-agent-executor.test.ts (9) cover AE1/AE5, hard cancel, re-entry,
follow-up, config snapshot, ceiling, and the generic-tier confirm-advance path,
using scripted adapters + a mock PTY seam. Engine typecheck clean; full
src/cli-agent suite + new tests green (144 passing).

+
+Wire the CLI Agent Executor as a selectable executor kind for the task execute
+path (U7). A workflow node with `config.executor === "cli-agent"` (plus
+`cliAdapterId` and optional `cliAutonomy`/`cliNotify`) now drives an engine-owned
+CLI coding agent (Claude Code / Codex / Droid / Pi / generic) through the execute
+step inside the task worktree.
+
+The new `cli-agent/task-session.ts` orchestrates the task↔session lifecycle:
+spawn in the worktree, mint the per-session hook token and write the hook scripts,
+inject the task prompt after readiness, subscribe to the authoritative state
+machine, and resolve on a positive completion signal (origin R20 gating — a
+native `done` advances the pipeline; the generic tier never auto-advances on idle
+and exposes a `confirmAdvance()` affordance instead). The resolved executor config
+is snapshotted at launch, so a mid-run node-config edit applies to the next run
+only. The PTY is reaped (recorded `completed`) at the execute→in-review handoff.
+
+Lifecycle semantics honor the existing contracts: a hard cancel
+(`moveTask(in-progress→todo)` / column-exit abort) SIGKILLs the CLI session via
+the same dispose/abort path API sessions use and marks it `killed` (never
+resume-eligible); a re-plan/RETHINK re-entry kills any prior live session and
+launches fresh; a follow-up to a done task resumes the recorded native session id
+when the adapter supports resume, else launches fresh. A PTY-pool ceiling
+(`CliConcurrencyLimitError`) surfaces as a clear queued/rejected task state rather
+than a silent stall.

+/**
+ * Task ↔ CLI session orchestration (CLI Agent Executor, U7).
+ *
+ * This module is the bridge between the task execute pipeline and the engine-
+ * owned CLI session machinery (U2 CliSessionManager + U3 TelemetryHub /
+ * state machine + U17 hook scripts). It takes a task + the resolved workflow-
+ * node executor config and runs one CLI agent through the execute step:
+ *
+ *   1. Spawn a CLI session in the task worktree (CliSessionManager.spawn). A
+ *      CliConcurrencyLimitError at the ceiling is propagated as a typed error
+ *      (the seam surfaces it as a queued/rejected task state — never a stall).
+ *   2. Mint the per-session hook token (TelemetryHub.issueToken) and write the
+ *      session-scoped hook scripts (writeSessionHookScripts) into a scratch dir.
+ *   3. Build the adapter launch settings (the Claude adapter consumes the written
+ *      hook-script paths via its settings flow). NOTE: the launch invocation is
+ *      computed by the manager from the settings we pass through `spawn`; this
+ *      module assembles those settings BEFORE spawn so the hooks are wired at
+ *      launch.
+ *   4. Inject the task prompt after readiness (manager.waitForReady → inject).
+ *   5. Subscribe to the state machine and resolve on a terminal signal (R20):
+ *        - native `done`           → success      (PTY reaped at handoff)
+ *        - generic-tier `idle`     → NEVER resolves; `confirmAdvance()` resolves
+ *                                    it as success (the operator affordance)
+ *        - `needsAttention`        → needs-attention (stall / userExited /
+ *                                    authFailed escalation)
+ *        - `killed`                → killed       (hard cancel / column exit)
+ *
+ * Config snapshot: the resolved executor config is captured at launch. A mid-run
+ * node-config edit therefore applies to the NEXT run only — this object holds the
+ * launch-time snapshot.
+ *
+ * Re-entry policy (caller-driven):
+ *   - A needs-replan / RETHINK re-entry launches a FRESH session: the caller
+ *     kills any prior live session for the task first (see
+ *     `killLiveTaskSessions`) and calls `launchCliTaskSession` again.
+ *   - A follow-up to a done task resumes the recorded native session id when the
+ *     adapter supports it (`followUp`); if resume is unsupported or fails the
+ *     follow-up falls back to a fresh launch.
+ *
+ * Pure engine code: no dashboard imports, no HTTP. The hub is the in-process
+ * telemetry sink; the dashboard route (U17) forwards validated hook POSTs into it.

+ *                      The task does NOT advance and is NOT a hard failure — it
+ *                      needs a human.
+ * - `killed`         — hard cancel / column exit SIGKILL'd the PTY. Never resume-
+ *                      eligible; the task left in-progress.
+ * - `user-exited`    — the child exited cleanly mid-task (no done). Surfaced as

Subject: [PATCH 050/112] feat(engine): execute and step-execute sessions run
 as the column agent

U4: seams stamp the governing node id into run context; a per-seam
resolveSeamColumnAgent feeds the core resolver and threads the effective
agent through resolveExecutorSessionModel, runtime hints, persona, memory
tools, and StepSessionExecutor attribution. Characterization tests pin the
no-binding path byte-identical. Gating/deferral principal moves in U5.

+Add per-column agent assignment for workflow columns, behind the combined `experimentalFeatures.workflowColumns` + `experimentalFeatures.workflowGraphExecutor` flags.
+
+A workflow column can now name a permanent agent from the registry plus a mode — `defer` (the column agent is the default for work in that column that carries no agent/model settings of its own) or `override` (the column agent supersedes node- and task-level agent/model settings). The binding applies to all session-running work attributable to the column's nodes: custom prompt/gate/script nodes, the execute seam's coding session, and step-execute sessions. Precedence is resolved by one shared `@fusion/core` resolver (`resolveColumnAgentBinding` + `resolveEffectiveAgent`) consumed by every reader, with defer/override expressed as explicit named rules and defer granularity all-or-nothing (an own agent identity OR a complete `modelProvider`+`modelId` pair suppresses the column agent). The binding keys off the node's declared IR column; foreach template nodes inherit the enclosing foreach node's column. A missing/deleted agent at resolution time logs and falls back to normal resolution — a live session is never aborted. The built-in default workflow carries no column agents and stays byte-identical (parity oracle); with either flag off, column agents are inert.

+ * Pins the regression-critical behavior the redesign must preserve byte-for-byte:
+ *   - one global + one project edit in a single session produce the expected
+ *     `updateGlobalSettings` / `updateSettings` patches with strict scope routing;
+ *   - clearing a project override emits null-as-delete;
+ *   - untouched inherited project values are NOT written (changed-only gate);
+ *   - explicit clears of global keys emit null, plain undefined is dropped.
+ *
+ * The split logic was lifted out of the modal into the pure `splitSettingsSave`
+ * helper; this test exercises it against the real `@fusion/core` key predicates
+ * so it stays honest about which keys land in which scope.

+/**
+ * Save-split logic for SettingsModal (U9 / KTD-10).
+ *
+ * The modal edits a single merged form that mixes global-scope and
+ * project-scope keys. On save it must split that form into two patches with
+ * strict scope separation and preserve three subtle semantics:
+ *
+ *   1. Global keys are routed via {@link isGlobalSettingsKey} to the global
+ *      patch; project keys via {@link isProjectSettingsKey} to the project
+ *      patch. (A key can be neither — server-only/UI-only fields are dropped.)
+ *   2. null-as-delete: an explicit clear (current value `undefined`, but the
+ *      initial value was defined) is written as `null` so it survives
+ *      `JSON.stringify` and tells the server to delete the key. Plain
+ *      `undefined` is dropped.
+ *   3. changed-only project writes: an inherited/effective project value that
+ *      the user never touched is NOT serialized as an explicit override —
+ *      doing so would silently break inheritance for every project setting on
+ *      every save. Only keys whose value differs from the initial project-scoped
+ *      value are written.
+ *
+ * This module is pure (no React, no network) so the regression-critical split
+ * behavior is characterized in isolation; the modal shell calls it and performs
+ * the actual `updateGlobalSettings`/`updateSettings` writes.

+ *
+ * Tunnel status, provider selection (Tailscale / Cloudflare), cloudflared
+ * install affordance, start/stop/use-existing flows, and the auth-link / QR
+ * tooling. This section is heavily stateful and side-effecting; rather than
+ * lift all of that into the section, the shell continues to own the remote
+ * state machine (status polling, busy-action guard, install handler, token
+ * previews) and the `runRemoteAction` wrapper. The section receives them via a
+ * single `remote` prop bag plus the modal form. API calls are imported directly
+ * here (pure module functions) so they don't bloat the prop surface. Behavior
+ * and i18n keys are preserved verbatim from the original inline JSX.

+Add CLI-agent one-shot sessions for the validator, planning, and CE plugin
+surfaces (U9). A one-shot session runs an adapter's non-interactive invocation
+(`claude -p`, `codex exec --json`, `droid exec --output-format json`,
+`pi --print`) to completion in a working directory, streams output to a
+read-only terminal (input disabled server-side via the durable
+`autonomyPosture.readOnly` flag the transport's `isReadOnlySession` honors),
+parses the adapter's structured JSON result, and reaps the PTY on exit.
+
+The new `cli-agent/one-shot-session.ts` returns a typed result: a success with
+the parsed payload, or a typed failure (`nonzero-exit` / `unparseable` /

+/**
+ * One-shot CLI agent sessions (CLI Agent Executor, U9).
+ *
+ * A *one-shot* session runs an adapter's NON-INTERACTIVE invocation
+ * (`claude -p`, `codex exec --json`, `droid exec --output-format json`,
+ * `pi --print`) to completion in a working directory, streams its output to a
+ * read-only terminal (so U10's attach surface works exactly as for interactive
+ * sessions — but with input disabled server-side), collects the output, parses
+ * the adapter's structured (JSON) result, and returns a typed result.
+ *
+ * Read-only enforcement: the dashboard transport's `isReadOnlySession` treats
+ * `validator`/`planning` purposes as inherently read-only, and ALSO honors an
+ * `autonomyPosture.readOnly === true` flag. One-shot sessions persist that flag
+ * unconditionally so a `ce` (or any future) purpose is read-only too — the flag
+ * is the durable, transport-readable signal, not a transient client hint.
+ *
+ * Design notes:
+ * - The non-interactive command is built by `buildOneShotLaunch`, keyed off the
+ *   adapter id. The interactive adapter launch builders intentionally don't
+ *   model the `-p`/`exec` forms (those drive a REPL); one-shot is a distinct
+ *   invocation that produces a single machine-readable result and exits.
+ * - Output is merged stdout+stderr (a PTY has a single stream). The structured
+ *   result is parsed from that stream per adapter. On a nonzero exit or an
+ *   unparseable result we return a typed failure carrying a BOUNDED tail of the
+ *   output as `stderr` (the best available diagnostic on a PTY).
+ * - The PTY is reaped on completion: spawn → wait-for-exit → the session
+ *   manager has already removed the live session and closed streams by the time
+ *   `waitForExit` resolves.

+Add the CLI agent resume coordinator and self-healing integration (U8). On
+engine start, sessions persisted as live (starting / ready / busy /
+waitingOnInput) are classified `engineDeath` and queued for resume respecting
+the session-manager concurrency ceiling. Resume verifies the recorded worktree
+still exists (missing → needsAttention, never a CLI spawned into a vanished
+directory), detects a dirty worktree (logged + flagged on the session record,
+resume proceeds), relaunches via the adapter's `buildResume` with the recorded
+native session id in the recorded worktree, re-attaches telemetry, and
+re-injects no prompt. Only `crashed`/`engineDeath` are resume-eligible
+(`killed`/`userExited`/`authFailed`/`completed` never); attempts are capped at 2
+with backoff; exhaustion, an unsupported adapter, a missing vendor session
+store, or an immediate spawn error route to needsAttention (a permanent-failure
+path, not a retry loop).
+
+Self-healing idle-worktree sweeps (`enforceWorktreeCap`, `cleanupOrphans`,
+unregistered-orphan reap) now skip a worktree backing a resume-eligible
+`cli_sessions` record via a narrow `isWorktreeResumeReserved` seam, and the
+stuck-task detector suppresses stuck/inactivity flagging while a task's CLI
+session is `waitingOnInput` via a narrow `isCliSessionWaitingOnInput` seam — the
+U3 stall backstop remains the only escalation while genuinely waiting.

+/**
+ * CliResumeCoordinator — engine-restart recovery for CLI agent sessions
+ * (CLI Agent Executor, U8).
+ *
+ * On engine start, sessions persisted as live (starting / ready / busy /
+ * waitingOnInput) were orphaned by the engine's death — there is no live PTY
+ * behind them. This coordinator finds those records, classifies them as
+ * `engineDeath`, and queues a resume that respects the session-manager
+ * concurrency ceiling.
+ *
+ * Resume semantics (KTD — termination taxonomy, resume-the-CLI):
+ * - Eligibility: ONLY `crashed` and `engineDeath` are resume-eligible
+ *   (`isResumeEligible`). `killed` / `userExited` are never auto-resumed;
+ *   `authFailed` and `completed` are never resumed. A record found live on
+ *   restart is reclassified to `engineDeath` (it had no chance to record a
+ *   terminal reason), making it eligible.
+ * - Worktree-existence precondition: the recorded worktree MUST still exist —
+ *   a missing worktree routes the session to `needsAttention`, NEVER a CLI
+ *   spawned into a vanished directory.
+ * - Dirty-tree detection: a dirty `git status` is logged and flagged on the
+ *   session record (under `autonomyPosture.resumeDirtyWorktree`), then resume
+ *   PROCEEDS — the flag surfaces to the UI.
+ * - Relaunch: via the manager's resume path (adapter `buildResume` with the
+ *   recorded `nativeSessionId`, in the recorded worktree). Telemetry is
+ *   re-attached (a fresh hook token + scripts via `wireTelemetry`/the hub).
+ *   NO prompt is re-injected — scrollback replays to viewers, the agent
+ *   continues from its own native transcript.
+ * - Attempt cap: 2 attempts with backoff (tracked on `resumeAttempts`).
+ *   Exhaustion, an adapter without resume support, a missing vendor session
+ *   store, or an immediate spawn error route to `needsAttention` (a permanent
+ *   failure path, NOT an infinite retry loop).
+ *
+ * The coordinator NEVER imports dashboard code. The worktree-existence check
+ * and the dirty-tree probe are injected seams so tests need no real git/FS.

Subject: [PATCH 055/112] feat(engine): effective column agent becomes the
 execution principal

U5: action-gating contexts, the heartbeat deferral gate, a two-pass
resumeTaskForAgent, and the reverse-direction agent.taskId guards (via a
new isAgentEffectivelyExecuting callback wired at the in-process runtime)
all consult the column-effective agent; the restart watcher re-resolves
column bindings per tick for bound graph sessions, hot-swapping on
agent-changed and falling back without restart on agent-deleted.

 Add per-column agent assignment for workflow columns, behind the combined `experimentalFeatures.workflowColumns` + `experimentalFeatures.workflowGraphExecutor` flags.
 
 A workflow column can now name a permanent agent from the registry plus a mode — `defer` (the column agent is the default for work in that column that carries no agent/model settings of its own) or `override` (the column agent supersedes node- and task-level agent/model settings). The binding applies to all session-running work attributable to the column's nodes: custom prompt/gate/script nodes, the execute seam's coding session, and step-execute sessions. Precedence is resolved by one shared `@fusion/core` resolver (`resolveColumnAgentBinding` + `resolveEffectiveAgent`) consumed by every reader, with defer/override expressed as explicit named rules and defer granularity all-or-nothing (an own agent identity OR a complete `modelProvider`+`modelId` pair suppresses the column agent). The binding keys off the node's declared IR column; foreach template nodes inherit the enclosing foreach node's column. A missing/deleted agent at resolution time logs and falls back to normal resolution — a live session is never aborted. The built-in default workflow carries no column agents and stays byte-identical (parity oracle); with either flag off, column agents are inert.
+
+The effective column agent is also the principal for the subsystems that previously assumed the running agent is always `task.assignedAgentId`: action gating (`buildActionGateContext` / `buildPermanentAgentGatingContext`) is computed for the agent actually running; heartbeat serialization honors it in both directions (the execute deferral gate, a second `resumeTaskForAgent` pass that re-dispatches tasks whose effective column agent matches, and a reverse-direction heartbeat-scheduler guard so an `allowParallelExecution=false` column agent never heartbeats concurrently with its own session); and a workflow-definition edit or agent runtimeConfig change that re-keys the column-effective agent/model hot-swaps the running graph session, while an agent deleted mid-session falls back without a restart.

+
+Add CLI-agent adapter launch settings, an autonomy approval gate, and workflow
+node-editor configuration for the CLI Agent Executor (U15).
+
+A new `cliAgents` slice of global settings holds per-adapter operator launch
+config — command override, extra args, autonomy mode, and env allowlist
+additions — validated and sanitized at the write boundary (unknown adapter ids
+and invalid fields are dropped). Shipped defaults are owned by the adapters.
+
+The autonomy gate closes the "adjacent settings" bypass: elevation requested
+through ANY channel (the autonomy field, extra args such as
+`--dangerously-skip-permissions`, an autonomy-toggling env var, or a non-default
+command override) is detected over the FULLY RESOLVED argv + env via per-adapter
+elevation markers plus a shared generic env-pattern set. `resolveEffectivePosture`
+derives the posture chip from the resolved invocation — never the autonomy field
+alone — and the effective posture is denormalized onto the session record at
+spawn. An elevated launch without a stored per-project approval fails with a
+typed `CliAutonomyNotApprovedError` instead of stalling. Approvals are per-project
++ per-adapter (mirroring the raw workflow-CLI-command approval precedent) and the
+approving principal in v1 is the daemon-token holder.
+
+The dashboard adds daemon-token-authed routes
+(`/api/cli-agents`, `/api/cli-agents/settings`,
+`/api/cli-agents/:adapterId/approve-autonomy` + revoke), a Settings section for
+per-adapter launch config with an explicit confirmation flow before elevated
+autonomy is approved, and a workflow node-editor block that surfaces an adapter
+picker (with native/hybrid/generic tier labels), an autonomy toggle, and the
+waiting-on-input notification mode (banner / banner+notify) when a node's executor
+is `cli-agent`. All new strings are localized in the `app` i18n catalog.

+/**
+ * CLI-agent autonomy posture resolution + elevation approval gate (U15).
+ *
+ * The autonomy approval gate's central invariant: **elevation expressed through
+ * ANY channel must be caught.** Operators can request bypass-permissions-style
+ * autonomy through four distinct settings channels:
+ *
+ *   1. the autonomy field        (`nodeConfig.cliAutonomy.autoApprove`, or the
+ *                                  settings `autonomyMode: "elevated"`),
+ *   2. extra args                (`--dangerously-skip-permissions` smuggled in),
+ *   3. env additions             (`*_DANGEROUS*` / `*_SKIP_PERMISSIONS*` vars),
+ *   4. a command override        (pointing the binary at an arbitrary path).
+ *
+ * A posture chip derived from the autonomy *field alone* would be false-safe
+ * when elevation rides one of the other channels. So `resolveEffectivePosture`
+ * derives the posture from the **fully resolved argv + env** — it asks the
+ * adapter to build the actual launch invocation (which already folds in the
+ * posture flags, extra args, and command override), then scans that argv plus
+ * the env additions against the adapter's declared elevation markers and a
+ * shared generic env-pattern set. A non-default command override is itself
+ * privileged.
+ *
+ * Any resolved elevation requires a stored per-project approval (mirroring the
+ * raw workflow-CLI-command approval precedent). `assertAutonomyApproved` throws
+ * a typed `CliAutonomyNotApprovedError` when elevation is present but no
+ * approval is recorded for the project — the caller surfaces this as a launch
+ * failure, never a stall.
+ *
+ * Pure engine policy: no HTTP, no DB. The approval lookup is injected as a
+ * small async predicate so the dashboard can back it with the project store.

 A workflow column can now name a permanent agent from the registry plus a mode — `defer` (the column agent is the default for work in that column that carries no agent/model settings of its own) or `override` (the column agent supersedes node- and task-level agent/model settings). The binding applies to all session-running work attributable to the column's nodes: custom prompt/gate/script nodes, the execute seam's coding session, and step-execute sessions. Precedence is resolved by one shared `@fusion/core` resolver (`resolveColumnAgentBinding` + `resolveEffectiveAgent`) consumed by every reader, with defer/override expressed as explicit named rules and defer granularity all-or-nothing (an own agent identity OR a complete `modelProvider`+`modelId` pair suppresses the column agent). The binding keys off the node's declared IR column; foreach template nodes inherit the enclosing foreach node's column. A missing/deleted agent at resolution time logs and falls back to normal resolution — a live session is never aborted. The built-in default workflow carries no column agents and stays byte-identical (parity oracle); with either flag off, column agents are inert.
 
 The effective column agent is also the principal for the subsystems that previously assumed the running agent is always `task.assignedAgentId`: action gating (`buildActionGateContext` / `buildPermanentAgentGatingContext`) is computed for the agent actually running; heartbeat serialization honors it in both directions (the execute deferral gate, a second `resumeTaskForAgent` pass that re-dispatches tasks whose effective column agent matches, and a reverse-direction heartbeat-scheduler guard so an `allowParallelExecution=false` column agent never heartbeats concurrently with its own session); and a workflow-definition edit or agent runtimeConfig change that re-keys the column-effective agent/model hot-swaps the running graph session, while an agent deleted mid-session falls back without a restart.
+
+Authoring lands in the workflow editor: the column panel gains a registry-backed per-column agent picker plus a defer/override mode toggle, bound columns are badged on their headers, and a node inside an override column shows that its own executor settings are superseded (so override never reads as a bug). Picker interaction states are explicit — flags off disables the picker with a tooltip naming both required flags, an in-flight fetch disables it, a failed fetch shows an inline error, and a stored `agentId` missing from the registry renders an "Agent not found" warning that preserves the IR until the author clears or replaces it. Agent references are validated at save time: the `POST`/`PATCH` workflow routes reject an unknown `agentId` with a typed 4xx naming the offending column, and binding an agent whose permission policy is broader than the project default requires an explicit `confirmPolicyEscalation` flag so override cannot silently re-key action gates to a more-privileged agent.

 The `workflowColumns` track introduces **IR v2** (`version: "v2"`), where a workflow additionally defines its own **columns** (`{ id, name, traits: [{ trait, config }] }`), places nodes in columns (`node.column`), and gains `hold`, `split`, and `join` node kinds. Columns become first-class, workflow-defined task state carrying composable **traits** (declarative flags + lifecycle hooks); this generalizes the fixed pipeline + the `gateMode` semantics documented below into per-column trait configuration. v1 graphs still parse and upgrade by synthesizing default-workflow columns. The column/trait model — the trait vocabulary, the substrate/policy line, the transition authority, and the graduation gate — is documented in **`docs/architecture.md` § 9 "Workflow-defined columns & traits"** and the **Concepts** glossary (column, trait, lane, hold node, split/join, default workflow, `transitionPending`). The whole v2 model is gated behind `experimentalFeatures.workflowColumns`; with the flag off, the v1 IR and the quality-gate `WorkflowStep` model below are unchanged.
 
+### Workflow IR v2 — per-column agent assignment
+
+A v2 column can optionally name a **permanent agent** from the agent registry, staffing every card that flows through it once instead of node-by-node or task-by-task. The binding is a first-class optional field on the column (not a trait — traits are board-transition policy; this is execution identity):
+
+```
+{ id: "review", name: "Review", traits: [],
+  agent: { agentId: "agent-001", mode: "defer" | "override" } }
+```
+
+**Binding shape.** `agent.agentId` is a non-empty registry agent id; `agent.mode` is `defer` or `override`. The field is omitted entirely when unset — a column with no `agent` key yields no binding, and the built-in default workflow carries none (it stays byte-identical, the parity oracle). Adding a binding forces the workflow to v2.
+
+**Which column governs.** The binding keys off the node's **declared** IR column (`node.column`), never the task's current board lane. A node with no declared column resolves normally (no column agent), even when other columns carry override bindings.
+
+**`defer` vs `override`.**
+
+- **`defer`** — the column agent is the default *only* when the work carries no agent/model settings of its own. "Own settings" is all-or-nothing: an own agent identity **or** a complete `modelProvider`+`modelId` pair suppresses the column agent entirely. An incomplete model pair (provider with no model id) does **not** count as own settings, so the column agent still wins (matching the executor's both-present model rule). The column agent is never blended with own settings — filling only the missing half would create hybrid identities that are impossible to audit.
+- **`override`** — the column agent supersedes node-level and task-level agent/model settings: identity, model, **and** persona.
+
+**Where it applies.** The effective agent governs all session-running work attributable to the column's nodes: custom prompt/gate/script nodes, the execute seam's coding session, and step-execute sessions. Raw CLI script nodes run no session, so the binding is a no-op there (the skip is audited). Every adoption is logged (`running as column agent '<id>' (<mode>)`) so the audit trail explains who ran and why.
+
+**Foreach template inheritance.** A node inside a `foreach` template subgraph inherits the **enclosing foreach node's** column, unless the template node declares its own `column` (which then wins). Each per-step instance session is attributed to the resolved column agent.
+
+**Principal semantics.** The effective column agent becomes the **principal**, not merely a model source. Action gating is computed for the agent actually running (a security boundary — never `task.assignedAgentId` when an override governs). Heartbeat serialization follows it in both directions: a column agent with `allowParallelExecution=false` is serialized like an assigned agent, the engine re-dispatches tasks whose *effective* column agent matches (not only `assignedAgentId` matches), and the heartbeat scheduler never lets a column agent heartbeat concurrently with its own override session. A workflow-definition edit or agent `runtimeConfig` change that re-keys the effective agent/model hot-swaps a running session, the same way a `task.modelProvider` change does today.
+
+**Missing-agent fallback.** A missing or deleted agent at resolution time logs and falls back to normal resolution — a live session is never aborted because its column agent was deleted mid-flight.
+
+**Flag requirements.** Column agents act only when **both** `experimentalFeatures.workflowColumns` and `experimentalFeatures.workflowGraphExecutor` are on; with either off the binding is inert (config is still stored and round-trips — only execution is gated), and the editor surfaces that the picker is disabled with a tooltip naming both flags.
+
+**Write-time validation.** Saving a workflow validates agent references: an unknown `agentId` is rejected with a typed 4xx naming the column. Binding an agent whose permission policy is broader than the project default requires an explicit policy-escalation confirmation (`confirmPolicyEscalation`) at save time, so override cannot silently re-key action gates to a more-privileged agent.
+
 ### Workflow IR v2 — step inversion (foreach, step-review, parse-steps, code)
 
 The **step-inversion** track makes task *steps* themselves workflow-modelable. Today the engine owns step policy end-to-end (PROMPT.md parsing, per-step review verdicts, RETHINK/REVISE control flow, merge blocking). Step inversion extracts exactly one new substrate capability — *run one step inside a task's session, and reset one step to its baseline* — and exposes everything else as authored graph structure. It is additive to IR v2 and gated by `experimentalFeatures.workflowGraphExecutor`. The default coding workflow is untouched and byte-identical (it keeps its monolithic `execute` seam and is the parity oracle); inversion is opt-in via custom workflows and a new built-in **stepwise coding workflow**.

+ * The intentional exceptions are the redirect stubs and the `MODEL_LANES`
+ * descriptor table, which only NAMES the keys (as `projectProviderKey` /
+ * `projectModelKey` string literals) so the surviving "default" lane can be
+ * rendered — those are not form bindings. We therefore match the precise binding

@@ -11,3 +11,9 @@ CLI nodes can run arbitrary commands (not just named scripts); the first run of
 Agents reach workflows too: the `fn_workflow_list`, `fn_workflow_get`, `fn_workflow_select`, `fn_workflow_create`, `fn_workflow_update`, and `fn_workflow_delete` tools (plus `fn_trait_list` for the column vocabulary) give agents the same author/list/select capability as the dashboard. These are exposed not only to the task executor but also to the chat and planning agents, so you can author and edit workflows directly in a chat or planning conversation; a guard test locks all six tool names to each lane to prevent silent exposure drift. Built-in workflows are now read-only in the editor (palette/inspector disabled, with a "Duplicate to edit" action), and a node's "Auto-approve requests" toggle now actually bypasses the CLI first-run approval pause.
 
 Also fixes a latent persistence bug where `pausedReason` was written to the in-memory task and read by queries but never stored by the task upsert or mapped back on read — so it was lost on every reload. This silently broke any pause/resume that depends on the reason (workflow CLI-approval and await-input nodes, token-budget pauses, worktrunk failures). The approve-CLI endpoint now derives the approved command solely from the task's pausedReason (ignoring any caller-supplied command), await-input nodes only resume when this node actually paused the task (not on a pre-existing steering comment), and write-capable custom nodes are refused until a task worktree exists so they never mutate the shared repo root.
+
+The editor itself got a major usability upgrade: card-style nodes with kind accents and live config summaries (model/agent/skill/command, gate mode, hold release, join mode); success/failure edge authoring on regular edges with distinct styling, parallel conditioned edges, and an author-time cycle guard; one-click auto-layout that respects column swimlanes; safe node/edge deletion with cascade semantics; proper dialogs (create/delete/discard) with inline rename, descriptions, and a dirty-state guard on every dismissal path; onboarding/empty states; and the Columns and Fields panels now live in the editor's left sidebar under the workflow list.
+
+The node editor is now the primary workflow surface: the header and mobile nav open it directly and the legacy Workflow Steps screen is retired. Existing flat steps migrate automatically (and idempotently) on first editor open — every step becomes an insertable template fragment in the new palette Templates section (alongside built-in and plugin step templates), and your default-on steps become a "Migrated steps" workflow that's set as the project default. Task creation now picks a workflow (applied atomically at create) instead of individual step checkboxes.
+
+Workflows and template fragments import/export as JSON files — with server-side validation, name-collision handling, and automatic stripping of approval-bypass flags from untrusted files. And you can ask AI to design a workflow: describe what you want in the create dialog (or redesign the active workflow from the toolbar) and a planning-lane model emits a validated graph, with interpreter-only branching flagged honestly.

+# Residual Review Findings — feat/column-agent-assignment
+
+Source: ce-code-review autofix run `20260605-003401-136dbfd5` (artifact: `/tmp/compound-engineering/ce-code-review/20260605-003401-136dbfd5/`), reviewing the column-agent-assignment feature against `docs/plans/2026-06-04-002-feat-column-agent-assignment-plan.md`.
+
+All other actionable findings from the review (validated P1 correctness bugs, R13 agent-path gate bypass, reliability guards, test gaps — findings #1-#10, #12-#18) were fixed on-branch in commit `fix(review): apply autofix feedback` before PR creation. One design-level residual was deferred to the tracker:
+
+## Residual Review Findings
+
+- **[P2]** `packages/dashboard/src/routes/register-workflow-routes.ts:119` — Column-agent policy-escalation gate is save-time-only (TOCTOU): broadening a bound agent's policy (or narrowing the project default) after save silently escalates the substituted principal with no re-confirmation. Filed: https://github.com/Runfusion/Fusion/issues/1431
+
+## Advisory notes (report-only, no action required)
+
+- `confirmPolicyEscalation` is a transient per-request flag; no persisted record of which policy state was confirmed.
+- KTD-4 hot-swap covers execute-seam sessions; step-session tasks are not hot-swapped mid-flight (documented limitation).
+- `resumeTaskForAgent` pass-2 performs sequential per-candidate IR resolution; consider a fast-path skip when no bindings are active if it shows up in profiles.
+- `effectiveColumnAgentByTask` is per-executor-instance while `graphRouting` is process-static — a second `TaskExecutor` instance would not see the first's column-bound sessions in the heartbeat reverse guard.

Enabled by default; only disable if it causes issues with your workflow.

+                worktrees still checked out on that branch (typically your project-root
+                checkout). <code>Stash + fast-forward</code> snapshots real local edits as a patch
+                against the previous tip, snaps the worktree to the new tip, then reapplies the
+                patch — untracked files that collide with newly-tracked paths are left in a temp
+                dir for manual recovery. <code>Fast-forward only</code> snaps cleanly when the

+                inverted as &quot;staged changes&quot; until you pull manually. Only applies to direct

+CLI agent terminal UI (U11): a shared `SessionTerminal` component (lazy-loaded
+xterm + fit/webgl/unicode11) that attaches to the U10 cli-sessions WebSocket
+with ACK flow control, a posture chip (baseline vs elevated), a read-only
+badge, session-idle/ended replay states, and a generic-tier confirm-advance
+strip. Adds a `terminal` tab to the task detail view driven by the lifecycle
+visibility matrix (live / read-only live / replay-idle / replay-ended / hidden)
+with live `cli:session:state` SSE merging, waiting-on-input and needs-attention
+task-card badges (distinct from staleness/stall badges), and extends
+`SessionNotificationBanner` with a `cli-agent` session type plus the pinned
+needs-attention variants (userExited / authFailed / resume-exhausted) and their
+actions. All new strings flow through the i18n catalogs.

+Add a first-class workflow settings mechanism and hard-move execution policy onto it.
+
+- **Workflow settings.** Workflows now declare typed settings in their IR (id, type, default, options) — the same authoring pattern as custom task fields. Setting *values* persist per `(workflow, project)` behind a single validating store authority, and the engine resolves *effective settings* per task (`stored value ?? declaration default`, dropping values that no longer validate). Built-in `builtin:coding` declares every moved key with its former default, so an untuned project behaves identically.
+- **Hard-move migration.** A one-time, idempotent, per-project migration relocates the step-execution, review/approval, and per-phase model-lane keys out of project/global settings into workflow setting values, removing them from the settings schema entirely. A `MOVED_SETTINGS_KEYS` tombstone list shields cross-node sync, v1 imports, and stale writers from resurrecting a moved key; a consistency test enforces one home per key.
+- **Settings UI redesign.** The Settings modal is rebuilt from shared schema-driven field primitives and per-section components; moved settings show a redirect stub linking to the workflow editor (one release). The new **Workflow editor → Settings** panel (Definitions/Values tabs) and the `fn_workflow_settings` agent tool edit values with typed validation.
+- **Export v2.** Settings export bumps to version 2 with a `workflowSettings` value section; importing a v1 export upgrades any moved key it carries into the appropriate workflow's values. Workflow settings are not synced across nodes yet (surfaced in the sync UI).

 ### Workflow Setting
 A typed setting declared by a workflow in its IR (id, type, default, options), mirroring the custom-task-field shape. Declarations describe the schema; *values* persist per workflow + project through a single validating store authority, so built-in workflows can carry values without their IR being editable. The engine consumes **effective settings** — stored value falling back to declaration default, with values that no longer validate against the current declaration dropped (never fed to execution).
 
+### Effective Settings
+The per-task, flat `Partial<Settings>`-shaped value map the engine reads at executor entry, composed from the task's resolved workflow: for each declared Workflow Setting, the stored `(workflowId, projectId)` value falls back to the declaration default, with stored values that no longer validate against the current declaration dropped. Resolution never throws — a missing or corrupt workflow degrades to the built-in coding declarations — so every read site receives a usable value. Because built-in declaration defaults are byte-equal to the legacy project-settings defaults, an untuned project resolves to identical behavior across the settings hard-move.
+
+### Moved Settings Keys
+The tombstone allowlist (`MOVED_SETTINGS_KEYS`) of the step-execution, review/approval, and per-phase model-lane keys that the one-time hard-move migration relocated from project/global settings into Workflow Settings. It is the single record of the old names and shields every surface that can encounter a legacy payload — cross-node sync diffs, v1 settings imports, and stale writers — from resurrecting a moved key. A consistency test enforces that a key lives in exactly one regime (project settings *or* the tombstone list, never both).
+
 ### Three-Tier Setting
 The named persistence pattern for a user preference on the dashboard: a device-local cache for instant reads, a write-through to Global Settings so other Surfaces see it, and a hydrate-on-mount from the server when no local value exists. A local or in-flight user choice always wins over server hydration, and changes propagate to other open tabs.

+## Workflow Settings
+
+Some knobs that used to live in this Settings reference as project settings are now
+**workflow settings**: they are declared by a workflow and their values are stored
+**per `(workflow, project)`**, not as ambient project settings. A workflow models
+*how* tasks execute, so the timeouts, review gates, and per-phase model lanes that
+govern that execution belong to the workflow.
+
+**Where to set them.** Open the **workflow editor** (the workflow node editor in the
+dashboard) and select the **Settings** panel. It has two tabs:
+
+- **Definitions** — the typed declarations and defaults (read-only for the built-in
+  `builtin:coding` workflow; editable for custom workflows).
+- **Values** — the per-project values for the workflow that is open. Values are
+  editable for any workflow, including built-ins. Edits batch and commit through a
+  single **Save** in the Values tab.
+
+**How values resolve.** The engine resolves *effective settings* per task as
+`stored value ?? declaration default`. A built-in workflow with no stored value
+falls back to the declaration default, which is byte-equal to the legacy project
+default — so an untuned project behaves exactly as before. Switching a project to a
+**new** custom workflow starts that workflow from its own declaration defaults, not
+the project's prior customized values.
+
+**Agents.** `fn_workflow_create`/`fn_workflow_update` accept `settings` declarations,
+and the `fn_workflow_settings` tool reads and writes values with the same typed
+validation as the editor (invalid values are rejected, never persisted). See
+[engine tools reference](../packages/cli/skill/fusion/references/engine-tools.md).
+
+**Sync & export.**
+
+- Workflow settings are **not synced across nodes yet** (a node-sync channel for the
+  value table is planned). Cross-node settings sync filters these keys out of its
+  diff and surfaces a "Workflow settings are not synced across nodes yet" note.
+- Workflow setting values **are** included in **settings export v2** under a
+  `workflowSettings` section keyed `workflowId → { settingKey: value }`. Importing a
+  v1 export upgrades any moved key it carries into the appropriate workflow's values
+  instead of writing it back into project settings.
+
+### Where did my setting go?
+
+These groups moved out of project settings and into workflow settings (built-in
+`builtin:coding` declares all of them with their former defaults):
+
+| Group | Keys (examples) |
+|---|---|
+| **Step execution** | `workflowStepTimeoutMs`, `runStepsInNewSessions`, `maxParallelSteps`, `workflowStepScopeEnforcement`, `strictScopeEnforcement`, `verificationFixRetries`, `maxPostReviewFixes`, `buildRetryCount` |
+| **Review / approval** | `requirePrApproval`, `requirePlanApproval`, `reviewHandoffPolicy`, `maxReviewerContextRetries`, `maxReviewerFallbackRetries` |
+| **Per-phase model lanes** | `executionProvider`/`executionModelId`, `planningProvider`/`planningModelId` (+ fallbacks), `validatorProvider`/`validatorModelId` (+ fallbacks), `titleSummarizerProvider`/`titleSummarizerModelId` (+ fallback) |
+
+In the dashboard Settings modal, the former locations now show a short redirect stub
+linking to the workflow editor (for one release). Set these in the workflow editor's
+**Settings → Values** tab for the workflow you want to tune.
+
+> Note: the global baseline model lanes (`executionGlobalProvider` etc.) and
+> integrity guarantees stay where they are — only the per-workflow process policy
+> moved.
+
 ## Project Settings
 
 Defaults from `DEFAULT_PROJECT_SETTINGS`; key scope from `PROJECT_SETTINGS_KEYS`.
 
+> **Moved keys retained for reference.** Some rows below — the step-execution,
+> review/approval, and per-phase model-lane keys listed under
+> [Where did my setting go?](#where-did-my-setting-go) — are no longer project
+> settings. They are documented here for type/default reference only; configure them
+> in the **workflow editor → Settings → Values** tab. They are not writable through
+> `PUT /api/settings`.
+
 | Setting | Type | Default | Description |
 |---|---|---:|---|
 | `globalPause` | `boolean` | `false` | Hard stop: terminate active engine sessions and pause scheduling immediately. |

+## Workflow Settings
+
+Workflows can declare **typed settings** in their IR — the same authoring pattern as
+custom task fields, one level up. A setting declaration carries `{ id, name, type,
+default?, options?, description? }` with the type whitelist `string | text | number |
+boolean | enum | multi-enum`. Declarations are validated at save (unique ids, type
+whitelist, options only for enum kinds, default validates against its own type).
+
+Setting **values** persist per `(workflowId, projectId)` in a dedicated value table,
+separate from the declarations: built-in workflows declare settings but their
+declarations are non-editable, while their *values* are writable per project. The
+engine resolves *effective settings* per task as `stored value ?? declaration
+default`, dropping any stored value that no longer validates against the current
+declaration (drop-on-orphan) and falling back to the default.
+
+The **step-execution**, **review/approval**, and **per-phase model-lane** knobs that
+used to be project settings are now workflow settings declared by `builtin:coding`
+with their former defaults. See
+[Settings Reference → Workflow Settings](./settings-reference.md#workflow-settings)
+for the full moved-key catalog, the editor walkthrough, and the export/sync posture.
+
+Authoring surfaces:
+
+- **Workflow editor → Settings panel** — Definitions (declarations/defaults) and
+  Values (per-project) tabs.
+- **Agent tools** — `fn_workflow_create`/`fn_workflow_update` accept `settings`
+  declarations; `fn_workflow_settings` reads/writes values.

+/**
+ * U10 — End-to-end characterization of the workflow-settings hard-move (R3, R6, R7).
+ *
+ * This is the parity-closure suite: it proves the whole move is behavior-preserving
+ * across one deterministic journey, with NO real polling and NO slow work (in-memory
+ * timers are unnecessary — every step is synchronous store/resolver work; the store
+ * is opened on a temp dir with a disk-backed DB so the raw `config.settings` row and
+ * the global settings file survive across the seeding/migration steps, exactly as the
+ * settings-migration suite does).
+ *
+ * The journey (single test):
+ *   a. Build a PRE-migration store state: a project with customized MOVED keys
+ *      (`workflowStepTimeoutMs`, `requirePrApproval`, `executionProvider`) written
+ *      into the RAW `config.settings` row the way a v108-era store would hold them —
+ *      BEFORE the migration runner fires (marker cleared, raw seeded). Pattern reused
+ *      from settings-migration.test.ts (`seedRawProjectSettings` + `clearMarker`).
+ *   b. Run the migration → assert effective values via `resolveEffectiveSettingsById`
+ *      equal the customized values (engine-parity anchor).
+ *   c. Edit a value via `store.updateWorkflowSettingValues` (the panel/tool write
+ *      path) → assert `resolveEffectiveSettingsById` reflects it.
+ *   d. Export via `exportSettings` (v2) → wipe (fresh store/project) → `importSettings`
+ *      → assert identical effective values, including the `workflowSettings` section
+ *      round-trip.
+ *   e. Assert NO moved key exists in raw project settings at any point post-migration,
+ *      and an unrelated settings save does not resurrect them.
+ *
+ * ── Surface-enumeration checklist (FN-5893 discipline) ────────────────────────────
+ * Every surface that touches workflow settings carries at least one assertion in a
+ * dedicated suite. The `surface-enumeration` describe block below asserts each of
+ * these files exists (cheap meta-test) so the parity coverage cannot silently rot:

+Read values — `effective` is what the engine actually consumes (declaration defaults filled in, orphaned values dropped); `stored` is the raw override map; `orphaned` lists stored entries with no current declaration (or a value that no longer validates). `set` returns the same `{stored, effective, orphaned}` shape:
 
 ```jsonc
 // fn_workflow_settings
 { "action": "get", "workflow_id": "builtin:coding" }
 // → { "workflowId": "builtin:coding",
 //     "stored":    { "workflowStepTimeoutMs": 600000 },
-//     "effective": { "workflowStepTimeoutMs": 600000, "reviewHandoffPolicy": "disabled", ... } }
+//     "effective": { "workflowStepTimeoutMs": 600000, "reviewHandoffPolicy": "disabled", ... },
+//     "orphaned":  [] }
 ```
+
+Patching a key to `null` clears any stored value for it — including a value left behind under an orphaned key — so `set` doubles as the way to drop orphans. To see the full declaration catalog (every setting id, type, and default) call `fn_workflow_get` on `builtin:coding`, whose IR `settings` array is the canonical catalog.

+# Residual Review Findings — gsxdsm/cleanupsettings
+
+Source: ce-code-review run `20260605-011952-1c8655ba` (mode:autofix) against `main` (BASE e5bab640f), reviewing the workflow-settings mechanism branch (plan: `docs/plans/2026-06-04-002-feat-workflow-settings-mechanism-plan.md`). 11 safe fixes were applied on-branch in `fix(review): apply autofix feedback`; the findings below were filed as tracker issues rather than fixed inline.
+
+## Residual Review Findings
+
+- [P2] `packages/core/src/store.ts:11848` — Migration may key workflow setting values by rootDir before project identity exists → [#1434](https://github.com/Runfusion/Fusion/issues/1434)
+- [P2] `packages/core/src/store.ts:12921` — deleteWorkflowDefinition cascade of workflow_settings rows is not transactional → [#1435](https://github.com/Runfusion/Fusion/issues/1435)
+- [P2] `packages/core/src/settings-export.ts:336` — v1 settings import fan-out overwrites existing per-workflow customizations → [#1436](https://github.com/Runfusion/Fusion/issues/1436)
+- [P2] `packages/dashboard/app/components/WorkflowSettingsPanel.tsx:584` — pending value edits made while save is in flight are cleared → [#1437](https://github.com/Runfusion/Fusion/issues/1437)
+- [P2] `packages/engine/src/merger.ts:11596` — runAiAgentForCommit throws if task deleted mid-merge (getTask for effective settings) → [#1438](https://github.com/Runfusion/Fusion/issues/1438)
+- [P2] `packages/engine/src/self-healing.ts:5020` — in-review sweep resolves effective settings for every task, not just candidates → [#1439](https://github.com/Runfusion/Fusion/issues/1439)
+- [P2] `packages/core/src/workflow-settings.ts:64` — WorkflowSettingRejection shape diverges from CustomFieldRejection → [#1440](https://github.com/Runfusion/Fusion/issues/1440)
+- [P2] `packages/dashboard/src/routes/register-settings-sync-routes.ts:107` — outbound settings push not tombstone-filtered (defense-in-depth) and untested → [#1441](https://github.com/Runfusion/Fusion/issues/1441)
+- [P2] `packages/core/src/store.ts:1587` — repeated silent settings-migration failure has no surfaced signal → [#1442](https://github.com/Runfusion/Fusion/issues/1442)
+- [P3] `packages/core/src/store.ts:11876` — migration drops customized values for in-use custom workflows lacking declarations → [#1443](https://github.com/Runfusion/Fusion/issues/1443)
+- [P3] test-helper and `kebab()` duplication across workflow-settings code → [#1444](https://github.com/Runfusion/Fusion/issues/1444)
+
+Validated false during synthesis: "migration's global null-out stripped by its own guard" — the migration calls `globalSettingsStore.updateSettings` directly (`store.ts:11963`), bypassing the guarded wrapper; the null-out is effective.
+
+Advisory (report-only, no ticket): `updateWorkflowSettingValues` read-modify-write lost-update under concurrent writers; cross-project v2 import can write orphan rows for unknown workflow ids; binary downgrade after migration runs moved policy at defaults (forward-only posture, documented in `docs/settings-reference.md`).

+Mobile terminal interaction for cli-agent sessions (U13). `SessionTerminal` now
+detects mobile viewports via the canonical breakpoint
+(`(max-width: 768px), (max-height: 480px)`) and renders a bottom input model in
+place of relying on xterm's hidden-textarea (unreliable on mobile): a visible
+text input that forwards typed text + `\r` as input frames on submit, plus an
+accessory key bar emitting exact control sequences — Esc (`0x1B`), Tab (`0x09`),
+a dedicated Ctrl-C (`0x03`), ANSI CSI cursor arrows (`CSI A/B/C/D`), and a sticky
+Ctrl modifier whose next key combines into a control byte (Ctrl-C `0x03`,
+Ctrl-D `0x04`, Ctrl-Z `0x1A`) with a visible active state.
+
+Bar keys apply the iOS composer survival pattern (pointerdown/mousedown
+preventDefault, action on click) so the input keeps focus, and the bar behaves as
+a fixed footer that lifts above the virtual keyboard via `useMobileKeyboard`
+(including its pinch-zoom `vv.scale > 1` guard, which is not treated as
+keyboard-open). xterm `onData` input stays attached (the bar is primary, not
+exclusive). Bar keys and the input are deliberate user keystrokes routed straight
+to the session input path. All new strings are localized in the `app` i18n
+catalog.

+CLI-agent hybrid chat (U12): a chat session can select a cli-agent executor and
+be driven by a long-lived CLI agent process. Adapter transcript telemetry maps
+to durable chat_messages rows at user/assistant/tool-summary granularity (raw
+tool noise stays in the terminal), with the shared `redactSecrets` pass applied
+before persistence so transcripts never become a secret store. Composer sends
+route through the inject path with FIFO queueing; the flush decision re-fetches
+authoritative session state rather than trusting a cached busy flag. The chat
+surface gains a transcript ↔ raw-terminal toggle (terminal owns input, composer
+hidden in terminal mode); generic-tier sessions render terminal-only with no
+toggle. New per-session `cliExecutorAdapterId` linkage on chat_sessions.

+//     transcript ↔ terminal toggle. Raw-terminal mode swaps the message list for
+//     <SessionTerminal> and HIDES the composer (the terminal owns input);
+//     toggling back restores the transcript and composer.
+//  2. Generic tier: terminal-ONLY. No toggle, no transcript pane — the affordance
+//     is absent, not empty (screen-output parsing for a structured transcript is
+//     out of scope for generic CLIs).
+//  3. Composer queued state: while the underlying CLI session is busy, sends are
+//     queued with a visible indicator. The flush decision is owned server-side
+//     (CliChatSessionRunner, which re-fetches authoritative state — the
+//     stale-isGenerating learning); this component only surfaces the queued count.

+// renderer (passed in as `renderTranscript`) so there is no parallel message UI.

+/**
+ * CLI-backed chat session runner (CLI Agent Executor, U12).
+ *
+ * When a chat session selects a cli-agent executor (`ChatSession.cliExecutorAdapterId`),
+ * the chat is driven by a long-lived CLI agent process instead of the standard
+ * model-provider path. This runner is the server-side bridge between that CLI
+ * session and the durable chat transcript:
+ *
+ *  - It spawns (or resumes) a `CliSessionManager` session with purpose "chat",
+ *    cwd = the configured working directory (or the project root), persisting the
+ *    native session id back onto the chat session for resume.
+ *  - Composer messages route through the inject path (FIFO, serialized by the
+ *    manager's write queue). While the session is busy, sends queue; the flush
+ *    decision re-fetches authoritative session state from the store rather than
+ *    trusting a cached/streamed busy flag (the stale-isGenerating learning,
+ *    docs/solutions/logic-errors/queued-chat-message-flush-trusts-stale-isgenerating.md).
+ *  - Adapter transcript telemetry events map to `chat_messages` rows at
+ *    user/assistant/tool-summary granularity. Fine-grained tool noise
+ *    (toolActivity, outputProgress, idle) stays in the terminal and is NOT
+ *    persisted — the durable transcript is the readable conversation, not the
+ *    raw scrollback.
+ *
+ * Secret hygiene: the shared `redactSecrets` pass runs on transcript text
+ * BEFORE persistence. Durable chat rows must not become a secret store — CLI
+ * agents routinely print bearer tokens and env dumps. See the test block in
+ * packages/dashboard/src/__tests__/chat-cli-sessions.test.ts for the
+ * characterized coverage of what `redactSecrets` catches and its known gaps.
+ *
+ * This module owns no PTY/adapter internals directly: it depends on narrow
+ * interfaces (`ChatStoreLike`, `CliSessionManagerLike`) so it is unit-testable
+ * with mocked PTY/adapters per the U12 constraints.

Subject: [PATCH 081/112] feat(dashboard): wire cli-agent chat surface and
 runner glue; fix stale engine mocks (U12 completion)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mount CliChatSurface in ChatView for cli-backed chat sessions (sessions carrying
cliExecutorAdapterId): the message-pane + composer region is delegated to the
surface (transcript/raw-terminal toggle for hybrid/native adapters, terminal-only
for the generic adapter), while regular sessions keep the standard composer. The
existing message list and composer JSX are captured once as render thunks and
passed through, so there is no parallel message/composer UI.

Add a narrow telemetry seam: TelemetryHub gains an optional onEvent tap (also
settable post-construction via setEventListener) invoked with each sanitized
event after routing — best-effort, a throwing listener never breaks ingest. This
is the seam the CliChatSessionRunner uses to build the durable transcript from
the same sanitized events the hook route already feeds the hub, without the hub
becoming a general subscriber bus.

Fix the stale @fusion/engine vi.mocks across dashboard tests: object-literal
mocks that fully replace the module now also return listCliAdapterDescriptors
(added by U15's cli-agent-settings route, evaluated at module load). Mocks that
spread importOriginal/importActual already pick it up.

Tests: new ChatView.cli-mount.test.tsx (cli session → CliChatSurface, regular
session → normal composer, generic → terminal-only); telemetry-hub onEvent tap
coverage. chat-attachment-routes, chat-cli-sessions, cli-agent-hooks-route,
ChatView.cli-toggle all green.

+Bootstrap the CLI Agent Executor runtime and wire it end-to-end.
+
+A new `createCliAgentRuntime` factory (engine) constructs the per-project bundle — a `CliSessionStore` over the project's existing core Database, a per-runtime adapter registry with all five bundled adapters, the `CliSessionManager` (PTY lifecycle), the `TelemetryHub` (per-session token registry rebuilt from live records), and the `CliResumeCoordinator` (relaunch re-mints a hook token + rewrites hook scripts) — returning the executor bundle, the `isWorktreeResumeReserved` / `isCliSessionWaitingOnInput` predicates, and a scoped `dispose`.
+
+The runtime is instantiated per project in `InProcessRuntime` behind the `experimentalFeatures.cliAgentExecutor` flag (opt-in, matching the `workflowGraphExecutor` precedent): the bundle threads into `TaskExecutorOptions.cliAgentRuntime`, the predicates feed the self-healing idle-worktree sweep and the stuck-task detector, and `resumeCoordinator.recoverOnStart()` runs non-blocking after engine start (errors logged, never thrown). The dashboard hook endpoint URL is derived from a server-threaded option, falling back to a localhost URL from `FUSION_DASHBOARD_PORT` (default 4040).
+
+The dashboard now resolves the project's `TelemetryHub` via `cliAgentHubResolver`, mounts the cli-sessions transport from the runtime's manager + store, and brokers cli-backed chat sends: a chat session with a `cliExecutorAdapterId` routes composer sends to a `CliChatSessionRunner` (instead of the model agent loop), and the hub's sanitized telemetry is routed per-session into the runner's transcript handler.

+ * - Registers all bundled adapters into a fresh {@link CliAdapterRegistry} (a
+ *   per-runtime registry, NOT the process-wide `defaultCliAdapterRegistry`, so
+ *   multi-project boots never collide on duplicate-registration).
+ * - Constructs the {@link CliSessionManager} (PTY lifecycle) and
+ *   {@link TelemetryHub} (per-session token registry, rebuilt from live store
+ *   records on construction).
+ * - Constructs the {@link CliResumeCoordinator}, wiring `reattachTelemetry` to
+ *   re-mint a hook token + rewrite the session's hook scripts on relaunch.
+ *
+ * It returns the {@link CliAgentRuntime} bundle the {@link TaskExecutor}
+ * consumes, plus the two narrow predicates the self-healing / stuck-task seams
+ * read, plus a `dispose` that tears the manager down cleanly (scoped SIGKILL of

+
+Fix a batch of CLI Agent Executor review defects:
+
+- **Schema-version gate**: bump `SCHEMA_VERSION` to 110 so a DB already at 109
+  runs migration 110 and gains the `chat_sessions.cliExecutorAdapterId` column
+  (it was previously short-circuited). Add the column to the compat-fingerprint
+  `MIGRATION_ONLY_TABLE_SCHEMAS.chat_sessions` entry so the fingerprint matches.
+- **Generic adapter double-wrap**: `formatInjection` no longer re-wraps injected
+  text in bracketed-paste markers when `bracketedPasteActive`; the session
+  manager's security path is the sole wrapper, so the generic adapter (like every
+  native one) only appends a carriage return.
+- **Output-filter cross-boundary bypass**: thread one carry buffer across the
+  scrollback→live seam in the CLI session WS bridge so a dangerous escape (e.g.
+  OSC 52) split across the seam is fully neutralized instead of the held
+  introducer being flushed verbatim into the scrollback frame.
+- **Output-filter overflow leak**: when an over-length carry begins with a
+  recognized dangerous introducer (OSC `ESC ]` / DCS `ESC P`), drop the
+  introducer instead of flushing it as literal, so it cannot recombine with a
+  later terminator at the client.
+- **Follow-up never resolves**: `followUp()` now drives the authoritative state
+  machine `done→busy` before injecting, so the re-armed result promise resolves
+  on the next positive `done` instead of hanging on an idempotent done.

Subject: [PATCH 086/112] fix(ci): align engine/schema test stubs with
 cli-agent surface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cli-agent executor feature added engine.getCliAgentRuntime() (called by
the CLI dashboard command at load) and bumped @fusion/core SCHEMA_VERSION
108→110. Update the stale test stubs:

- cli dashboard.test.ts: add getCliAgentRuntime() to the mock FnAgent class
  (returns undefined; runDashboard handles the no-runtime path). Fixes 52
  failures all rooted at `cwdEngine?.getCliAgentRuntime is not a function`.
- roadmap-store.test.ts: the roadmap store layers on core's Database, so its
  schema version tracks core; assert 110 instead of 108.

Subject: [PATCH 087/112] fix(ci): repair dashboard tests broken by cli-agent
 feature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- TaskFieldsSection.css: restore the toggle knob fill to the themed
  var(--card) token (was hardcoded to #fff on this branch), which the
  AgentListModal theme-token guard scans all app CSS for and rejects.
- ListView.test.tsx: add fetchBoardWorkflows + api to the ../../api mock;
  TaskDetailModal (rendered via the embedded detail) now calls both at mount
  for board workflows and the cli-sessions lookup, so the object-literal mock
  must provide them ("No X export is defined on the ../../api mock").
- auto-merge-toggle-blank.mobile.test.tsx / board-mobile-initial-render.test.tsx:
  revert the runOnlyPendingTimers→runAllTimers change; with the installed rAF
  shim that re-schedules itself, runAllTimers loops forever and trips vitest's
  10000-timer infinite-loop abort.

+/**
+ * Boot smoke check — the merge gate's "the app starts and serves" proof.
+ *
+ * Verifies, against the *built* workspace (run `pnpm build` first):
+ *   1. The CLI answers `--help` with exit 0.
+ *   2. `fn serve` boots a real HTTP server on an ephemeral port and
+ *      GET /api/health returns 200 within the timeout.
+ *   3. The server shuts down cleanly on SIGTERM.
+ *
+ * Safety properties (see scripts/check-no-kill-4040.mjs and AGENTS.md):
+ *   - Never binds or touches port 4040 / FUSION_RESERVED_PORTS — an ephemeral
+ *     port is requested from the OS (listen on 0) and double-checked against
+ *     the reserved list.
+ *   - Never kills anything except the child process it spawned itself.
+ *   - Runs with an isolated $HOME (mkdtemp) so it cannot read or corrupt a
+ *     developer's real fusion.db or auth state.
+ *
+ * Exit code is the verdict: 0 = boots and serves, non-zero = broken, with
+ * captured child stderr on stdout for CI logs.

Subject: [PATCH 092/112] refactor(ci): thin PR gate to
 lint/typecheck/build/gate; demote full suite to non-blocking push-to-main
 workflow

- pr-checks.yml: gate job = boot smoke + pnpm test:gate; shards/slow/inventory removed
- full-suite.yml (new): 4-way shards, engine slow tier, inventory guard on push to main
- ci.yml deleted (trigger-disabled since FN-1541; was dead config)
- ci-workflow.test.ts rewritten to pin the new gate shape; release/signing blocks preserved
- docs/contributing.md: pnpm test:gate is the merge gate; verify:workspace repositioned as deep opt-in

BRANCH-PROTECTION CUTOVER: set required checks to exactly [Lint, Typecheck, Build, Gate] after merging; open PRs must rebase.

 - Package-scoped hooks now mirror this bootstrap for fresh worktrees where needed: `@fusion/dashboard` and `@fusion-plugin-examples/dependency-graph` run `pretest: node ../../scripts/ensure-test-artifacts.mjs`.

 `test:ci:shard` is a CI-focused entrypoint (`scripts/ci-test-shard.mjs`) that deterministically balances workspace packages with `test` scripts by counting package-local `**/__tests__/**/*.test.{ts,tsx,mjs}` files, auto-splitting oversized packages into virtual shard entries (`{ name, shardIndex, shardCount }`), then assigning entries in descending weight order with best-fit placement for unsplit entries (closest under-budget fit, otherwise minimum overshoot) while keeping slices of the same package on different shards when possible. Whole entries run as grouped `pnpm --filter <pkg> test` calls, and virtual entries run one-by-one via `pnpm --filter <pkg> test -- --shard <index>/<count>`. This keeps coverage reproducible while improving shard balance.
 
-`pnpm test` now uses a changed-only entrypoint (`scripts/test-changed.mjs`) for faster local iteration. It resolves the comparison base from `.changeset/config.json` (`baseBranch`) and runs only affected workspaces from `pnpm-workspace.yaml` (both `packages/*` and `plugins/**`) using safe package-first filtering (`pnpm --filter <pkg> test`). It automatically falls back to the full suite when the run is forced (CI / `--full`), the git comparison base or diff cannot be resolved, no changes are detected, shared/root test infrastructure changes, or changed workspace paths cannot be resolved to a workspace package (fail-safe coverage behavior).
+`pnpm test` now uses a changed-only entrypoint (`scripts/test-changed.mjs`) for faster local iteration. It resolves the comparison base from `.changeset/config.json` (`baseBranch`) and runs only affected workspaces from `pnpm-workspace.yaml` (both `packages/*` and `plugins/**`) using safe package-first filtering (`pnpm --filter <pkg> test`). It runs the merge-gate suite first, then the affected set. The full suite runs only on explicit opt-in (`--full` / `pnpm test:full`); shared-infrastructure changes and unresolvable diffs widen the affected set but never escalate to an implicit full-suite run (the old escalation was the local OOM path).
 
 Root test entrypoints (`pnpm test`, `pnpm test:full`, and `pnpm test:ci:shard`) now use a shared CPU-aware default worker budget instead of fixed low values. By default, Fusion sets `FUSION_TEST_TOTAL_WORKERS` to `max(4, min(12, cpuCount - 1))` and `FUSION_TEST_CONCURRENCY` to `2` (clamped to the total budget), while still honoring explicit overrides from `VITEST_MAX_WORKERS`, `FUSION_TEST_TOTAL_WORKERS`, and `FUSION_TEST_CONCURRENCY`.

Subject: [PATCH 094/112] feat(test): pnpm test runs gate + affected set;
 remove implicit full-suite escalation (the local OOM path)

- decideExecutionPlan: implicit wide-blast reasons (missing base, diff failed,
  no changes, shared infra, unmapped package) route to new gate mode instead of full
- CI===true force-full branch removed (CI no longer calls test-changed.mjs)
- changed mode runs pnpm test:gate before the affected set
- full suite reachable only via explicit --full / FUSION_TEST_FULL=1
- characterization tests updated + new only-explicit-full invariant test

+- A flake INSIDE the merge gate is evicted, not skipped: remove its line from the `engine-core` allow-list in `packages/engine/vitest.config.ts` (the eviction PR does not need the flaky test to pass).
+- A second quarantine in the same subsystem is a product-race smell — look at the product code before the deletion clock runs out (see `docs/solutions/ui-bugs/skill-autocomplete-highlight-reset-on-swr-revalidation.md`: a flake "stabilized" three times was a real race).

-## Required workspace gates
+## The merge gate
 
-Tests are required. Typechecks and manual verification are not substitutes for assertions.
+CI blocks PRs on exactly four checks (`.github/workflows/pr-checks.yml`): **Lint, Typecheck, Build, Gate**. The Gate job runs the boot smoke (`scripts/boot-smoke.mjs`: CLI `--help` + a real `fn serve` answering `GET /api/health`) and `pnpm test:gate` (the curated `engine-core` vitest project + the CI-shape test). Everything else — the 4-way shards, the engine slow tier, the dashboard inventory guard — runs NON-BLOCKING in `.github/workflows/full-suite.yml` on push to main.
+
+Gate membership is the explicit allow-list in `packages/engine/vitest.config.ts` (`engine-core` project). Admission requires evidence of value (the test catches real regressions); tests never graduate in by default. A flaky gate test is evicted by deleting its allow-list line — the eviction PR does not need the flaky test to pass. The whole `engine-core` project must stay under ~60s wall-clock.
+
+**The gate's blind spot, stated honestly:** typecheck + build + boot smoke + curated suite does not run the union suite a merge creates. Logic regressions outside the curated set land non-blocking by design — that is the accepted trade: the old broad gate caught no recalled real bugs while consuming ~70% of shipping time in flake triage.
+
+## Required workspace gates
 
 Use the narrowest command that exercises the behavior you changed, then broaden before reporting completion.
 
 ```bash
-pnpm test              # changed-only workspace tests; falls back to full gate in safety contexts
-pnpm test:full         # full workspace quality gate
+pnpm test              # gate suite + changed-only affected tests (bounded; never full-suite)

-pnpm verify:workspace  # canonical pre-merge gate: lint -> test:full -> build
+pnpm verify:workspace  # deep opt-in verification: lint -> test:full -> build (NOT the merge gate)
 ```
 
 `pnpm test:full` runs each package's default test script with capped worker fanout (`FUSION_TEST_TOTAL_WORKERS=4 FUSION_TEST_CONCURRENCY=2 pnpm -r --workspace-concurrency=2 test`). Do not casually raise worker counts; dashboard/jsdom and integration-heavy packages destabilize when oversubscribed. Use `VITEST_MAX_WORKERS=<n>` only for targeted package-level investigation.

+## Quarantine ledger and the deletion ratchet
+
+Flaky tests are quarantined ON SIGHT and deleted on a 2-week clock. This is written policy with minimal mechanics — deliberately no loader module, no automation (see the AGENTS.md standing rule "Flaky Tests Are Quarantined on Sight").
+
+**To quarantine a test** (a test that failed without a corresponding real bug in the change), in one commit:
+
+1. Add an entry to `scripts/lib/test-quarantine.json`:
+   `{ "file": "<repo-relative test path>", "reason": "<why + link to the failing run>", "quarantinedAt": "YYYY-MM-DD" }`
+2. Add a matching one-line `exclude` entry to that package's vitest config.
+
+**The clock:** an entry expires 14 days after `quarantinedAt`. Whoever touches the suite and finds an expired entry deletes the test file, its ledger entry, and its config exclude (git history is the archive). `scripts/check-test-inventory.mjs --diff` stays deliberately unwired in CI because it would fail on exactly these deletions.
+
+**Rescue** (before the clock runs out) requires both: evidence the test catches real regressions, and a root-cause fix for the flake. Stabilization passes — widened timeouts, retries, loosened assertions — are appeasement, not rescue, and are banned (for agents especially).
+
+**Gate eviction:** a flake inside the merge gate cannot block all merges while red — it is evicted by removing its line from the `engine-core` allow-list (no quarantine entry needed unless it should also leave the non-blocking tier).
+
+**Product-race escalation:** a second quarantine in the same subsystem is a smell that the flake is a real product race, not test noise — look at the product code before deleting (a dashboard flake was "stabilized" three times before being found to be a real race; see `docs/solutions/ui-bugs/skill-autocomplete-highlight-reset-on-swr-revalidation.md`).

+# Fast, Trusted Test Gate
+
+## Summary
+
+Shrink the PR merge gate to a minimal trusted set — typecheck, build, boot smoke, and a small curated core-engine suite — demote everything else to non-blocking, and install a deletion ratchet: flaky tests are quarantined on sight and deleted after 2 weeks unless rescued with evidence. De-duplicate the overlapping shard runs across CI workflows.
+
+---
+
+## Problem Frame
+
+PRs currently trigger multiple test shard jobs at 4–10 minutes each, and the suite appears to run in both `.github/workflows/ci.yml` (3 shards) and `.github/workflows/pr-checks.yml` (4 shards). Failures are mostly flaky/infra — timeouts, port conflicts, OOM kills — not real bugs. Local developers hit OOM running tests.
+
+The cost is severe: roughly 70% of shipping time goes into a loop of asking an agent to fix the failure and re-running. The agent-fix loop has a known degradation mode — agents appease flaky tests (widen timeouts, add retries, loosen assertions) rather than fix root causes, draining whatever signal the tests had.
+
+Against that cost, the suite's recalled value is zero: no PR test failure in recent memory caught a bug that would have actually broken users. ~3,880 test files are currently pure cost. Substantial speed infrastructure already exists on this branch (affected-only runner with content-hash caching in `scripts/test-changed.mjs`, CI sharding, a `.slow` split, isolation checks) — speed tuning alone has not fixed the problem because the core issue is trust, not throughput.
+
+---
+
+## Key Decisions
+
+- **Thin trusted gate over broad coverage.** The merge gate guarantees only what the maintainer needs to merge without anxiety: typecheck, build, boot smoke, core-engine correctness. The evidence (zero recalled real catches across ~3,880 files) says breadth was not buying protection.
+- **Delete over quarantine-forever.** Quarantine is a 2-week waiting room, not a retirement home. Without a deletion deadline, the demoted suite rots into a permanently red zombie that still consumes attention.
+- **Policy, not machinery.** The ratchet is a written rule (in `AGENTS.md` and contributor docs), not new test infrastructure. This repo's history shows a pattern of answering test pain with more test machinery (sharding, isolation checks, lock runners, kill guards); this change deliberately breaks that pattern.
+- **Agents are banned from "fixing" flaky tests.** When an agent encounters a flaky test, the correct action is quarantine, never appeasement. This stops the suite-weakening loop.
+- **Reuse existing infrastructure.** `scripts/test-changed.mjs`, the `.slow` split, and shard timing artifacts stay. The change is what blocks merges, not how tests run.
+
+---
+
+## Requirements
+
+**Merge gate**
+
+- R1. The PR merge gate consists of: typecheck, build, a boot smoke check (the app starts and serves), and a curated core-engine test suite.
+- R2. The curated core-engine suite runs as a single CI job targeting under ~3 minutes, with zero known-flaky tests admitted.
+- R3. The gate is the only merge-blocking test signal; no other test job can block a PR.
+- R4. If no suitable boot smoke check exists, a single small one is created (see Dependencies).
+
+**CI de-duplication**
+
+- R5. The full suite runs at most once per PR event; the overlapping shard runs between `.github/workflows/ci.yml` and `.github/workflows/pr-checks.yml` are consolidated.
+- R6. Tests outside the gate run as a non-blocking job (post-merge or scheduled); their failures never block a PR.
+
+**Deletion ratchet (policy)**
+
+- R7. Any test observed to fail without a corresponding real bug (flake) is quarantined on sight — removed from all blocking and non-blocking runs, not retried, not patched.
+- R8. A quarantined test is deleted after 2 weeks unless someone rescues it with evidence that it catches real regressions; rescue requires fixing the flake at the root, not appeasing it.
+- R9. The quarantine/delete rule and the agent prohibition on flaky-test appeasement (no widened timeouts, added retries, or loosened assertions to make a flake pass) are written into `AGENTS.md`.
+- R10. Admission to the blocking gate requires evidence of value; tests do not graduate into the gate by default.
+
+**Local development**
+
+- R11. The default local test command (`pnpm test`) runs the gate suite, sized so it cannot OOM a typical dev machine.
+- R12. Running anything larger locally is opt-in via explicitly named commands.
+
+---
+
+## Acceptance Examples
+
+- AE1. **Covers R7, R8.**
+  - **Given:** a test fails on a PR, and the failure does not correspond to a bug in the change.
+  - **When:** a maintainer or agent triages it.
+  - **Then:** the test is quarantined (skipped everywhere) in that same PR or a follow-up, with a dated marker; 2 weeks later it is deleted unless rescued with evidence.
+- AE2. **Covers R3, R6.**
+  - **Given:** a non-gate test fails in the non-blocking run.
+  - **When:** a PR is open.
+  - **Then:** the PR's mergeability is unaffected; the failure surfaces as information only.
+- AE3. **Covers R9.**
+  - **Given:** an agent is asked to deal with a red flaky test.
+  - **When:** it consults `AGENTS.md`.
+  - **Then:** it quarantines the test rather than widening timeouts, adding retries, or weakening assertions.
+
+---
+
+## Success Criteria
+
+- PR wall-clock for required checks drops from tens of minutes to under ~5 minutes.
+- Maintainer time spent on the fix-and-rerun loop drops from ~70% to near zero; a red gate reliably indicates a real problem.
+- No local OOMs from the default test command.
+- Suite size shrinks over time via the ratchet rather than growing unboundedly.
+
+---
+
+## Scope Boundaries
+
+- No new test machinery: no auto-quarantine infrastructure, no flake-scoring system, no test-value telemetry (the Approach C ratchet automation was considered and rejected as more of the machinery pattern).
+- No root-cause fixing of existing flaky tests as part of this work — flakes exit via quarantine and deletion.
+- Healthy non-gate tests survive indefinitely in the non-blocking run; this work does not mass-delete tests that aren't flaky.
+- Coverage targets and coverage tooling are untouched.
+
+---
+
+## Dependencies / Assumptions
+
+- **Unverified:** whether a usable boot smoke test already exists. If not, R4 creates one — kept deliberately small.
+- **Unverified:** the exact trigger overlap between `ci.yml` and `pr-checks.yml` shard jobs on PR events; confirmed shard matrices exist in both, but trigger conditions need checking during planning.
+- The existing `.slow` split and `scripts/test-changed.mjs` remain the mechanism for selecting and running tests; this work changes gating, not the runner.
+- Branch protection / required-checks settings are adjustable to match the new gate.
+
+---
+
+## Outstanding Questions
+
+**Deferred to planning**
+
+- Which engine tests make the curated gate suite (selection criteria: deterministic, fast, covering core orchestration logic the maintainer actually relies on).
+- Quarantine mechanics: skip annotation vs. exclusion list vs. moving files — whichever is cheapest with the existing runner.
+- Where the non-blocking run lives (post-merge on main vs. scheduled) and how its results surface without demanding attention.

+# refactor: Shrink PR merge gate to a fast trusted set with a deletion ratchet
+
+## Summary
+
+Replace the current 9-runner PR gate (lint, typecheck, build, 4 test shards, dashboard curated-gate guard, engine slow tier) with a thin trusted gate — 4 blocking checks: lint, typecheck, build, and a gate job combining boot smoke + the curated `engine-core` suite, with the gate job's test run under ~1 minute. (Lint is preserved from the existing gate as status quo; origin R1 does not name it.) Everything else moves to a non-blocking workflow on push to main. A quarantine ledger plus 2-week deletion ratchet (written policy, minimal mechanics) keeps flaky tests from re-accumulating, and local `pnpm test` is re-defaulted so developers cannot OOM.
+
+---
+
+## Problem Frame
+
+PR failures are mostly flaky/infra and consume ~70% of maintainer shipping time in an agent-fix-and-rerun loop; no recalled PR test failure caught a real user-facing bug (see origin: docs/brainstorms/2026-06-04-fast-trusted-test-gate-requirements.md). Research corrected one origin assumption: there is **no double shard run** — `.github/workflows/ci.yml` is trigger-disabled (`workflow_dispatch` only, per FN-1541). The live gate is `.github/workflows/pr-checks.yml` alone. The local OOM path is also pinned: `shouldForceFullSuite` in `scripts/test-changed.mjs` (~line 431) escalates almost any shared-file change to a full-suite run at `--workspace-concurrency=2`, with dashboard lanes requesting 6GB heaps.
+
+---
+
+## Key Technical Decisions
+
+- **The gate gets a dedicated command (`pnpm test:gate`); CI never invokes `pnpm test`.** `scripts/test-changed.mjs` hard-forces the full suite when `CI === "true"` (~line 1064), so any gate job calling `pnpm test` silently expands to everything. A dedicated command is the only way the ~1 min target is structurally guaranteed.
+- **Gate membership is an explicit allow-list, not a glob.** A new `engine-core` vitest project in `packages/engine/vitest.config.ts` with an enumerated include list (precedent: the existing `engine-default`/`engine-reliability`/`engine-slow` project split). Recorded membership makes R10 (tests earn their way in) enforceable, and lets a flaky gate test be evicted by editing the list — no need for the flaky test itself to pass (resolves the chicken-and-egg eviction problem).
+- **The non-blocking tier is a separate workflow file, not jobs inside `pr-checks.yml`.** A red full-suite run must not paint the gate's workflow red, or "red means real" dies on day one. New `full-suite.yml` triggered on push to main carries the 4 shards, engine slow tier, and inventory guard.
+- **`ci.yml` is deleted and `packages/cli/src/__tests__/ci-workflow.test.ts` is rewritten in the same unit.** That test hard-asserts the current CI shape (ci.yml exists, 3-shard matrix, pr-checks 4-shard matrix, `docs/contributing.md` gate wording). Deleting the workflow without rewriting the test makes the change self-inconsistent. The rewritten test guards the *new* gate shape and is admitted to the gate suite — a test that guards the gate's own shape earns blocking status.
+- **Quarantine ledger is a dated JSON file modeled on `scripts/lib/dashboard-curated-skiplist.json`, with `check-test-inventory.mjs --diff` left unwired.** The dashboard skiplist (entries with mandatory `reason`, shared between a guard script and vitest excludes) is the proven template; the ledger adds `quarantinedAt` so the 2-week clock is computable. `--diff` would fail CI on any test deletion — the exact opposite of the ratchet — so it stays unwired, documented as a deliberate exemption.
+- **Quarantine stays on-sight (origin decision), with a product-race escalation note in the policy.** Institutional learning (`docs/solutions/ui-bugs/skill-autocomplete-highlight-reset-on-swr-revalidation.md`) documents a flake "stabilized" three times that was a real product race. The policy keeps on-sight quarantine but states: a second quarantine in the same subsystem is a product-race smell worth a look before the deletion clock runs out. No triage gate, no machinery.
+- **Local `pnpm test` = gate suite + affected-package tests, with the force-full fallback removed.** Keeps the value of changed-code coverage (the affected-package expansion in `test-changed.mjs` already works) while deleting the OOM path: `shouldForceFullSuite` no longer escalates to a full recursive run locally; shared-infra changes run the gate suite plus a bounded affected set instead. `pnpm test:full` remains the explicit opt-in full suite.

+
+---
+
+## Requirements
+
+Carried from origin (R-IDs below are the origin's; see origin doc for full text).
+
+**Merge gate**
+
+- R1–R3. Gate = typecheck, build, boot smoke, curated `engine-core` suite; gate job's test run ~1 min; only merge-blocking test signal. (Lint stays as a separate pre-existing blocking check — status-quo preservation, not new scope from R1.)
+- R4. Boot smoke is greenfield — verified that nothing real exists (`packages/cli/src/commands/__tests__/serve.test.ts` mocks `listen`; the only artifact smoke lives in the disabled `ci.yml`).
+
+**CI de-duplication (revised by research)**
+
+- R5 (revised). No double run exists; the work is deleting dead `ci.yml` and consolidating the gate in `pr-checks.yml`.
+- R6. Non-gate tests run non-blocking in `full-suite.yml` on push to main; failures never block a PR.
+
+**Deletion ratchet**
+
+- R7–R10. Quarantine on sight; delete after 2 weeks unless rescued; policy in `AGENTS.md` including the agent appeasement ban; gate admission requires evidence.
+
+**Local development**
+
+- R11–R12. `pnpm test` cannot OOM (gate + bounded affected set, no force-full); bigger runs are explicit opt-ins.
+
+---
+
+## Implementation Units
+
+### U1. Curated `engine-core` gate suite and `test:gate` command
+
+- **Goal:** A single fast command that runs the gate's test content, locally and in CI.
+- **Requirements:** R1, R2, R10.
+- **Dependencies:** none.
+- **Files:** `packages/engine/vitest.config.ts`, `packages/engine/package.json`, `package.json` (root), `scripts/test-timings.json` (read-only input for selection).
+- **Approach:** Add an `engine-core` vitest project with an explicit include list. Selection criteria: deterministic (no module-level shared-state bleed, no real timers/network), fast (use `scripts/test-timings.json` per-file data; total budget ~60s single-threaded, leaving headroom under 1 min with boot smoke), and covering invariants the KB marks regression-prone: merge-queue trigger-gate eligibility, shared-branch-group landing/promotion idempotency, fork-point/files-changed attribution, executor/scheduler core paths. Exclude `reliability-interactions/**` and `*.slow.test.ts` outright (heaviest, single-threaded). Root script `test:gate` runs the `engine-core` project plus the rewritten CI-shape test from U3. Exact file list is execution-time discovery against timing data — the criteria above are binding, the list is not pre-enumerable here.
+- **Patterns to follow:** the existing three-project split in `packages/engine/vitest.config.ts` (lines ~50–95).
+- **Test scenarios:** Test expectation: none — config/selection unit; its verification is the gate run itself (below).
+- **Verification:** `pnpm test:gate` passes locally in under ~1 min cold; running it 5× consecutively produces 5 green runs (flake screen); it executes only the allow-listed files (verify via vitest `list`).
+
+### U2. Boot smoke check
+
+- **Goal:** A real "the app starts and serves" check — greenfield (R4).
+- **Requirements:** R1, R4.
+- **Dependencies:** none.
+- **Files:** `scripts/boot-smoke.mjs` (new), `package.json` (root, `test:gate` integration or separate `smoke:boot` script).
+- **Approach:** Script builds nothing itself (gate job already runs after `pnpm build` artifacts exist or reuses the build job's dist cache — mirror the dist-artifact cache steps in `pr-checks.yml` lines ~86–121). It starts the dashboard server on an ephemeral port (respect `FUSION_RESERVED_PORTS`; never touch port 4040 — see the kill-guard conventions in `scripts/check-no-kill-4040.mjs`), polls an HTTP endpoint until 200 or a hard timeout (~60s), asserts the CLI binary answers `--help`, then shuts down cleanly. Exit code is the verdict.
+- **Patterns to follow:** the packaged `--help` smoke in `scripts/release.mjs`; server-start handling in `packages/cli/src/commands/serve.ts` (the real one, not the mocked test).
+- **Test scenarios:**
+  - Happy path: server starts → 200 within timeout → clean shutdown → exit 0.
+  - Error path: server fails to bind / crashes → nonzero exit with captured stderr.
+  - Error path: port already in use → picks another ephemeral port rather than failing or killing anything.
+- **Verification:** `node scripts/boot-smoke.mjs` exits 0 on a built workspace and nonzero when the dashboard entry point is deliberately broken.
+
+### U3. Delete `ci.yml`, rewrite the CI-shape test, update CONTRIBUTING wording
+
+- **Goal:** Remove the dead workflow without leaving the repo self-inconsistent.
+- **Requirements:** R5 (revised).
+- **Dependencies:** U4 (the new pr-checks shape must be settled so the test asserts it; land in the same PR).
+- **Files:** `.github/workflows/ci.yml` (delete), `packages/cli/src/__tests__/ci-workflow.test.ts` (rewrite), `docs/contributing.md`, `README.md` (command block the test pins, if affected).
+- **Approach:** The test's first describe block loads `ci.yml` in `beforeAll` — deleting the workflow without removing that block crashes the entire suite at setup, not just one assertion. Delete the whole CI-workflow describe block; rewrite the PR-checks describe block (drop the 4-shard-matrix and no-pre-test-build assertions, add the new invariants); **preserve** the unrelated version.yml/release.yml/test-release.yml/code-signing describe blocks sharing the file. New invariants: `pr-checks.yml` contains the gate jobs (lint, typecheck, build, gate) and no shard matrices; `full-suite.yml` exists, triggers only on push to main, and contains the demoted jobs; `docs/contributing.md` names `pnpm test:gate` as the merge gate (the old "canonical pre-merge gate" string lives at `docs/contributing.md:83`). This test joins the gate suite (via U1's `test:gate`).
+- **Patterns to follow:** the existing assertion style in `ci-workflow.test.ts` (YAML load + structural expectations).
+- **Test scenarios:** (this unit IS a test)
+  - Asserts gate job set and absence of shard matrices in `pr-checks.yml`.
+  - Asserts `full-suite.yml` trigger is push-to-main only (no `pull_request`).
+  - Asserts `docs/contributing.md` gate wording matches the new commands.
+- **Verification:** rewritten test passes against the new workflows and fails if a shard matrix is reintroduced into `pr-checks.yml`.
+
+### U4. Rework `pr-checks.yml` and create `full-suite.yml`
+
+- **Goal:** The blocking gate becomes lint + typecheck + build + gate; demoted jobs move to a separate non-blocking workflow.
+- **Requirements:** R1, R2, R3, R6.
+- **Dependencies:** U1, U2.
+- **Files:** `.github/workflows/pr-checks.yml`, `.github/workflows/full-suite.yml` (new).
+- **Approach:** `pr-checks.yml` keeps `lint`, `typecheck`, `build`, and gains a `gate` job (boot smoke + `pnpm test:gate`) reusing the dist-artifact cache; it loses `test-shards`, `test-slow`, and `test-inventory-guard`, and its `push: main` trigger (post-merge signal moves to full-suite.yml). `full-suite.yml` runs on `push: branches: [main]` with the 4-shard matrix, engine slow tier, and inventory guard moved verbatim, keeping the per-shard timing artifact upload. Keep the `pretest` guards (`check-no-nohup`, `check-no-kill-4040`) on any path that runs tests. Cutover (manual admin step, do immediately after merge): update branch protection required checks to exactly `Lint`, `Typecheck`, `Build`, `Gate` — stale names like `Test shard 1/4` left required will block every PR forever ("Expected — waiting for status"). Open PRs must rebase onto post-change main before merging.
+- **Test scenarios:** covered by U3's rewritten CI-shape test (Covers AE2: a red `full-suite.yml` run does not affect PR mergeability — verify once live by observing a PR merge during a red main run).
+- **Verification:** a test PR shows only the 4 gate checks, total wall-clock under ~5 min; a deliberate failure in a demoted test does not block that PR.
+
+### U5. Quarantine ledger
+
+- **Goal:** A single recorded place for quarantined tests, feeding both vitest excludes and the 2-week clock.
+- **Requirements:** R7, R8.
+- **Dependencies:** none.
+- **Files:** `scripts/lib/test-quarantine.json` (new), vitest configs of packages that gain quarantined entries (exclude entries maintained by hand), `scripts/check-test-inventory.mjs` (doc comment only — `--diff` exemption note).
+- **Approach:** Schema per entry: `{ "file": "<repo-relative test path>", "reason": "<why, link to failing run>", "quarantinedAt": "YYYY-MM-DD" }` — modeled on `scripts/lib/dashboard-curated-skiplist.json` but with the date the ratchet needs. **No loader module, no CLI flag** (a shared module wired into vitest configs would itself be new test machinery — the failure mode the origin rejected). Quarantining a test = add the ledger entry AND add a matching one-line `exclude` entry to that package's vitest config, by hand, in the same commit; the ledger is the dated record, the config exclude is the mechanism. The 2-week sweep is performed by whoever (human or agent) touches the suite, per policy in U7 — an entry is expired when `quarantinedAt` is older than 14 days. Document that `check-test-inventory.mjs --diff` stays unwired because it would fail on ratchet deletions.
+- **Patterns to follow:** `scripts/lib/dashboard-curated-skiplist.json` (data file with mandatory `reason`, mirrored by config excludes).
+- **Test scenarios:** Test expectation: none — a data file plus hand-maintained config excludes; no executable surface to test. (Covers AE1: a quarantined file listed in the ledger with its config exclude no longer appears in the package's vitest run — verify via vitest `list`.)
+- **Verification:** adding a real test file to the ledger plus its config exclude removes it from `pnpm test:gate` and shard discovery without editing the test file itself.
+
+### U6. Local `pnpm test` re-default
+
+- **Goal:** Developers cannot OOM from the default command (R11), and changed-code coverage is preserved.
+- **Requirements:** R11, R12.
+- **Dependencies:** U1.
+- **Files:** `scripts/test-changed.mjs`, `package.json` (root).
+- **Approach:** `pnpm test` becomes: run `test:gate`, then affected-package tests via the existing changed-file → package → reverse-dependents expansion. Remove the local full-suite escalation: `shouldForceFullSuite` (~line 431) no longer triggers a recursive full run — shared-infra changes now run gate + a bounded affected set, with a printed note naming `pnpm test:full` for the full sweep. The `CI === "true"` force-full branch (~line 1064) is removed (CI no longer calls this script). `test:full`, `test:serial`, `test:fast`, `verify:workspace` keep their current full-suite semantics as explicit opt-ins; docs reposition `verify:workspace` as the deep pre-release check, not the pre-merge gate.
+- **Execution note:** characterization-first — `scripts/__tests__/` has existing coverage of test-changed behavior; capture the current selection behavior you're keeping before removing the escalation paths.
+- **Test scenarios:** (extend `scripts/__tests__/`)
+  - Changed file in one package → that package + reverse-dependents selected (unchanged behavior).
+  - Changed shared-infra file (e.g. `.github/workflows/x.yml`) → no full-suite escalation; gate + affected set only, hint printed.
+  - `--full` flag still runs the full suite (opt-in preserved).
+- **Verification:** `pnpm test` after touching a workflow file completes without spawning the recursive full run; memory stays bounded (no 6GB dashboard lanes invoked).
+
+### U7. Policy docs: ratchet, appeasement ban, gate semantics
+
+- **Goal:** The policy is written where humans and agents actually look (R9).
+- **Requirements:** R7, R8, R9, R10.
+- **Dependencies:** U1–U6 (documents the shipped reality).
+- **Files:** `AGENTS.md`, `docs/testing.md`.
+- **Approach:** `AGENTS.md`: rewrite line ~69 ("Tests are required. Typechecks/manual checks are not substitutes.") to describe the gate-vs-non-blocking split; add the ratchet as a standing rule adjacent to FN-5048 (~lines 79–85): quarantine on sight via ledger entry; delete after 2 weeks unless rescued with evidence and a root-cause fix; **agents must never appease a flaky test** (no widened timeouts, added retries, loosened assertions — quarantine instead); a flake *inside the gate* is evicted from the allow-list, not skipped; a second quarantine in the same subsystem is a product-race smell — look before the clock runs out (see `docs/solutions/ui-bugs/skill-autocomplete-highlight-reset-on-swr-revalidation.md`). `docs/testing.md`: new section with ledger schema, rescue procedure, gate admission criteria (evidence of value), and the known blind spot stated honestly: the gate does not run the union suite a merge creates — logic regressions outside the curated set land non-blocking by design. Mind the AGENTS.md add/add pointer-line merge convention (`docs/solutions/best-practices/merge-conflict-extraction-vs-semantics-and-parallel-bootstrap.md`).
+- **Test scenarios:** Test expectation: none — documentation unit. (AE3 — agent consults AGENTS.md and quarantines instead of appeasing — is enforced by the policy text this unit writes; U3's test pins the CONTRIBUTING wording.)
+- **Verification:** AGENTS.md and docs/testing.md describe the shipped gate accurately; no remaining references to the 4-shard PR gate or `verify:workspace` as "the canonical pre-merge gate".
+
+---
+
+## Scope Boundaries
+
+- No new test machinery: no auto-quarantine, no flake-scoring, no test-value telemetry, no quarantine loader module (see origin). The ledger JSON + hand-maintained vitest config excludes are the entire mechanical surface.
+- No root-cause fixing of existing flaky tests; flakes exit via quarantine and deletion.
+- Healthy non-gate tests survive indefinitely in `full-suite.yml`; no mass deletion.
+- Release pipelines untouched: `version.yml`/`release.yml` already run zero tests (verified), so nothing weakens; the consequence — regressions can reach main and ship behind build+typecheck+smoke — is the accepted thesis of this change.
+- Coverage tooling untouched.
+
+### Deferred to Follow-Up Work
+
+- Capturing the vitest auto-kill incident, port-4040 kill guards, and `.slow` split conventions into `docs/solutions/` (learnings researcher flagged these exist only in auto-memory/AGENTS.md).
+- A scheduled `--write-timings` refresh if shard balance in `full-suite.yml` degrades once PR-driven timing uploads stop (accept staleness initially).
+- Extending the `.slow`-style project split to non-engine packages if their non-blocking lanes ever need tiering.
+
+---
+
+## Risks & Dependencies
+
+- **Branch-protection cutover is the sharpest edge.** Required checks are matched by job name; leaving a removed name required blocks all PRs indefinitely. Mitigation: U4 names the exact new check set; do the admin update immediately after merge; audit open PRs and require rebase.
+- **Gate blind spot (deliberate).** Typecheck + build + smoke + curated suite does not test the union a merge creates; documented honestly in U7.
+- **Curated suite quality risk.** If the allow-list admits a latent flake, the gate loses trust fast. Mitigation: 5×-consecutive-green screen in U1 verification; eviction rule in U7.
+- **Timing snapshot staleness** once shards leave PRs (deferred above) — affects only non-blocking shard balance.
+- **Branch protection settings are server-side** — unverifiable from the repo; the actual required-check list at cutover time must be read from GitHub settings, not assumed.

 **Gate eviction:** a flake inside the merge gate cannot block all merges while red — it is evicted by removing its line from the `engine-core` allow-list (no quarantine entry needed unless it should also leave the non-blocking tier).
 
+**Gate admission:** the mirror operation — add the test's path to the `engine-core` `include` array in `packages/engine/vitest.config.ts`, citing the evidence of value (a real regression it caught) in the PR. Keep the project under its ~60s wall-clock budget.

 **Product-race escalation:** a second quarantine in the same subsystem is a smell that the flake is a real product race, not test noise — look at the product code before deleting (a dashboard flake was "stabilized" three times before being found to be a real race; see `docs/solutions/ui-bugs/skill-autocomplete-highlight-reset-on-swr-revalidation.md`).

Subject: [PATCH 099/112] Address PR review feedback (#1432)

- delimiter-safe foreach instance-id resolution via IR-validated candidates
- restart watcher handles binding removal/defer-flip and re-keys the reverse
  heartbeat guard on agent change/delete
- governing-node stamp owned by the pass-initiating foreach instance (race fix)
- editor: policy-escalation confirm/retry handshake on save; foreach children
  inherit the override note; project-scoped agent fetches; picker disabled on
  registry fetch error; column-agent strings in the canonical i18n catalog
- tests: update-tool escalation surface, PATCH escalation route, parity bound
  to run-derived stages, try/finally cleanup, deterministic event waits,
  symmetric defer surfaces, binding-release regression

Subject: [PATCH 102/112] Address PR review feedback (#1433)

- always dispose AI design session (try/finally) + rejecting-agent test
- prune expired design rate-limit entries per check
- apply workflowId precedence in createTaskWithReservedId
- compare-and-set migrated project default (no pre-transaction snapshot)
- reject fragment ids in setDefaultWorkflowId at the write boundary
- guard stripApprovalBypassFlags against malformed template nodes
- hoist duplicate stepToFragmentIr call in migration loop
- auto-layout preserves unplaced nodes (strictColumnForY)
- second same-pair connection births a failure edge for condition-capable sources
- insertFragment expands foreach templates into child nodes (lossless round-trip)
- copyIrWithFreshIds remaps namespaced foreach child layout keys
- discard stale AI-edit results after workflow switch
- i18n: returnEmptyString:false so empty locale placeholders fall back to en
- test fixes: schema-version titles, migrate idempotency assertion, TaskForm post-resolve + cross-mode regression, deterministic waits

Subject: [PATCH 103/112] Address PR review feedback (#1453)

- boot-smoke: shutdown verdict now requires SIGTERM actually delivered and a
  clean exit (code 0 or SIGTERM); EADDRINUSE port race retries with a fresh
  port (3 attempts)
- test-changed: rename shouldForceFullSuite -> isSharedInfraChange (it routes
  to gate mode, not full); run the changed-mode gate under the isolation guard
- workflows: least-privilege permissions (contents: read) on pr-checks and
  full-suite

 ### Three-Tier Setting
 The named persistence pattern for a user preference on the dashboard: a device-local cache for instant reads, a write-through to Global Settings so other Surfaces see it, and a hydrate-on-mount from the server when no local value exists. A local or in-flight user choice always wins over server hydration, and changes propagate to other open tabs.
 
+### Translation Placeholder
+An empty-string value for a catalog key in a non-English locale, marking "not yet translated." Placeholders are intentionally backfilled when keys are added; at runtime they are treated as missing (never rendered), falling back through the locale chain to English. A non-empty value — even an English one left in a non-en catalog — is rendered as-is.

 ### Supported Locale
 A language tag in the closed set Fusion ships translations for. Any external tag (browser, environment, flag) is normalized into this set or rejected — never passed through raw. Chinese tags route by script and region so Traditional-script users are never silently served Simplified, and the two Chinese variants never collapse into a generic base tag.

+# Empty-string locale placeholders render blank UI (i18next returnEmptyString default)
+
+## Problem
+
+The repo's translator workflow backfills `""` placeholders into non-en catalogs for untranslated keys, on the assumption that empty values fall back to English at runtime. They don't: i18next's default `returnEmptyString: true` treats `""` as a *found* value, so es/fr/ko/zh users saw blank buttons, nav labels, and dialog copy for every new key — even though components pass inline English defaults (`t("key", "Default")`).
+
+## Symptoms
+
+- New UI strings render blank in any non-English locale while en looks correct.
+- The inline second-argument default to `t()` does not rescue it — `""` short-circuits the fallback chain entirely.
+- Verified empirically (i18next 26.x): `t("empty", "InlineDefault")` returns `""` when the active locale defines the key as `""`.
+
+## What Didn't Work
+
+- Assuming the standing convention was safe because hundreds of `""` placeholders pre-existed — the convention had been silently rendering blanks all along for any key reached in a non-en locale.
+- Relying on inline `t()` defaults as a safety net — they only apply when the key is *missing*, not empty.
+
+## Solution
+
+One config line in the shared i18next init (`packages/i18n/src/config.ts`, `baseInitOptions()`):
+
+```ts
+returnEmptyString: false,
+```
+
+With this set, `""` values are treated as missing and fall through the fallback chain (`fallbackLng` → en, or the inline default). Locale files stay untouched, the `""`-placeholder translator convention keeps working, and every existing empty placeholder is fixed at once.
+
+Empirical check that settles the question in seconds (run against `node_modules` i18next, initialized like the app):
+
+```js
+// lng: "fr", resources: { fr: { empty: "" }, en: { empty: "EnglishValue" } }
+t("empty", "InlineDefault")
+// returnEmptyString true  (default) → ""           ← blank UI
+// returnEmptyString false           → "EnglishValue"
+```
+
+## Why This Works
+
+i18next resolution asks "does the key exist with a usable value?" — `returnEmptyString` defines whether `""` is usable. The default (`true`) is meant for apps where empty is a legitimate translation; in a placeholder-backfill workflow it's exactly wrong, because every placeholder is an intentional "not translated yet" marker.
+
+## Prevention
+
+- When adopting any `""`-placeholder catalog convention, set `returnEmptyString: false` in the same commit — the two are a package deal.
+- Don't trust the inline-`t()`-default mental model; prove fallback behavior with a 5-line init script before relying on it.
+- **Related catalog trap (hit twice in the same PR):** `pnpm i18n:extract` prunes keys whose usages it cannot see (CLI/TUI surfaces, dynamic keys) — it deleted live keys like `taskFields.*` and `common.cancel` from `en/app.json`. After running extract, semantically diff catalogs against the base ref (flatten both JSONs, assert zero removed/changed keys vs upstream, only intended additions) before committing. The content sanity test `packages/i18n/src/__tests__/config.test.ts` ("has real en content") exists because of this; prefer hand-adding keys + `i18n:sync`/`i18n:types` over trusting `i18n:extract` output wholesale.

+
+## Problem
+
+A new SQLite migration block (`applyMigration(110, ...)` adding `chat_sessions.cliExecutorAdapterId`) was added to `packages/core/src/db.ts`, but the `SCHEMA_VERSION` constant was only bumped to `109`. Any database already at version 109 never ran migration 110, so the new column was missing on every upgraded DB — while brand-new databases worked fine.
+
+## Symptoms
+
+- Runtime `no such column: cliExecutorAdapterId` on databases that had been initialized before the change.
+- Fresh databases (created after the change) had the column and worked — masking the bug in most local/dev setups and in any test that builds a DB from scratch.
+- Every migration test hard-coded `getSchemaVersion()` to `109`, which actively *masked* the defect rather than catching it.
+
+## What Didn't Work
+
+- Schema-from-scratch tests passed: a fresh DB starts at version 0 and falls through *all* migration blocks (ending at 110), so it incidentally gets the column. The bug only reproduces on the upgrade path (a DB sitting at exactly the stale constant value).
+- Per-package targeted test runs during implementation stayed green because no test seeded a DB at version 109 to exercise migration 110.
+
+## Solution
+
+Set the version constant to the highest migration target, and add an invariant test so the two can never drift again.
+
+```ts
+// packages/core/src/db.ts
+// BEFORE
+const SCHEMA_VERSION = 109;        // but an applyMigration(110, ...) block exists below
+// AFTER
+const SCHEMA_VERSION = 110;
+```
+
+The migrate loop gates on this constant:
+
+```ts
+// Any DB whose stored version is >= SCHEMA_VERSION returns BEFORE later blocks run.
+if (version >= SCHEMA_VERSION) return;
+```
+
+So a DB at 109 satisfies `109 >= 109` and returns *before* the `if (version < 110)` block — the migration is permanently skipped.
+
+Two secondary fixes that travel with this class of change:
+
+1. **Update the compat/fingerprint surface.** `MIGRATION_ONLY_TABLE_SCHEMAS.chat_sessions` (which feeds `SCHEMA_COMPAT_FINGERPRINT`) also has to list the new column, or the declared schema drifts from the migrated schema.
+2. **Seed-at-stale-version migration test.** Add a test that seeds a DB at the *previous* version with the old table shape, runs `init()`, and asserts both the new column exists and `getSchemaVersion()` equals the new constant:
+
+```ts
+// seed __meta schemaVersion = '109' + a chat_sessions table, then:
+db.init();
+const cols = db.raw.prepare("PRAGMA table_info(chat_sessions)").all();
+expect(cols.some((c) => c.name === "cliExecutorAdapterId")).toBe(true);
+expect(getSchemaVersion()).toBe(110);
+```
+
+## Why This Works
+
+The version constant is the *only* gate on whether later migration blocks execute. A migration block whose target exceeds the constant is dead code on the upgrade path. Bumping the constant to match the highest block re-arms the gate; the seed-at-stale-version test reproduces the exact upgrade path that fresh-DB tests skip.
+
+## Prevention
+
+- **Invariant test: the constant equals the highest migration target.** The most durable guard is a test that scans the migration blocks for the maximum `applyMigration(N)` / `if (version < N)` target and asserts `SCHEMA_VERSION === maxTarget`. This catches the drift mechanically regardless of which migration was added.
+- **Always add a seed-at-previous-version migration test** alongside any new migration — fresh-DB tests structurally cannot catch a skipped-on-upgrade migration.
+- **Treat hard-coded version assertions as a smell.** Many tests asserting `toBe(<oldVersion>)` will need updating on a bump; if updating them feels like whack-a-mole, that is the signal an invariant test should own the number instead.
+- **When adding a column, update every declared-schema mirror** (compat fingerprint maps, schema snapshots) in the same change — a migration that adds a column the canonical schema map omits is a second, quieter drift.

 ### Trait
 Composable column configuration: declarative flags (e.g. `complete`, `archived`, `countsTowardWip`) plus optional lifecycle hooks (`guard`, `gate`, `onEnter`, `onExit`, `releaseCondition`). Built-in and plugin-contributed traits register through one registry. Sync `guard` hooks and the `complete`/`archived` flags are built-in-only; plugin traits get async hook points only. A column's effective flags are the merged flags of its traits; conflicting compositions are rejected at save (server-side and in the editor).
 
+### Column agent
+A permanent agent binding on a workflow-defined column — a registry agent plus a mode — staffing all session-running work attributable to that column (custom nodes, the execute seam's coding session, per-step sessions; foreach template nodes inherit the enclosing foreach's column unless they declare their own). `defer` makes the column agent the default, applying only when the work carries no own agent identity and no complete model pair; `override` supersedes node- and task-level agent/model settings wholesale.
+
+Requires both the workflow-columns and graph-executor flags; with either off, bindings are inert at execution time. A missing or deleted agent degrades to normal resolution without aborting a live session. Binding an agent whose permission policy is broader than the project default requires explicit confirmation at save time on every write surface.
+
+### Effective agent (execution principal)
+The agent identity that actually runs a piece of work after column-agent precedence resolves — and the principal every identity-keyed subsystem must consult: permission gating, heartbeat serialization in both directions, resume re-dispatch, and mid-flight change detection. It may differ from the task's assigned agent under an override binding, and one task may have multiple effective agents across concurrent branch sessions.
+
 ### Lane
 A horizontal row on the multi-lane board, one per workflow in use by visible cards. Each lane renders its own workflow's columns. Tasks with no workflow selection appear in the Default workflow's lane; every card appears in exactly one lane. Zero-card lanes are hidden; lanes are collapsible with persisted state.

+# Per-entity execution-principal override: the full blast-radius checklist
+
+## Context
+
+The column-agent feature (PR #1432) lets a workflow column bind a registry agent that supersedes task/node agent settings (`defer`/`override`). The auto-merge-override lesson already taught "consult the override at every trigger gate, not just the action site." This feature showed the *execution-principal* variant has an even wider blast radius: plan review, code review, and two rounds of PR bots each found another subsystem still keyed on the old identity (`task.assignedAgentId`) — found one at a time, at increasing cost.
+
+## Guidance
+
+When work can run as an identity different from the one stored on the entity, enumerate and re-key ALL of these up front (Fusion's catalog; analogous sets exist elsewhere):
+
+1. **Session identity** — model resolution (`resolveExecutorSessionModel` runtimeConfig arg), persona, memory tools, attribution id.
+2. **Permission gating** — `buildActionGateContext`/`buildPermanentAgentGatingContext` must receive the agent *actually running* (security boundary, not UX).
+3. **Serialization, BOTH directions** — the deferral gate (`shouldDeferForHeartbeat`) AND the reverse guards keyed on `agent.taskId` in `agent-heartbeat.ts` (an agent may be effectively executing work it isn't assigned to → `isAgentEffectivelyExecuting` callback, wired at every scheduler construction site).
+4. **Wake-up/resume queries** — `resumeTaskForAgent`'s task-SELECTION filter, not just its gate input; a second pass matching the *effective* identity. Watch for nodes that live only in nested structures (foreach templates are not in `ir.nodes` — walk subgraphs).
+5. **Change detection / hot-swap** — the restart watcher diffs *task fields*; an override sourced from a workflow definition or agent config needs its own invalidation path, including the **release** branch (binding removed, or defer re-resolving to own settings) which must also clear the tracked principal and reverse-guard map.
+6. **Kill-switch parity** — if the rollback story is "disable flag X," every execution-path entry point must actually read flag X. Gate the single choke point (resolver installation) AND any path that resolves independently (resume pass 2 resolved the IR directly and needed its own guard).
+7. **Write-surface parity for safety gates** — a confirmation gate (policy escalation) added to the HTTP route is bypassed by agent tools writing through the store; share one validator (`validateColumnAgentBindings` in core) across ALL write surfaces.
+
+Precedence itself: one shared core resolver with explicit named branches (no `??` collapse), discriminated result for audit, and all-or-nothing own-settings semantics matched to the existing model resolver's both-present rule.
+
+## Why This Matters
+
+Each missed subsystem is a distinct production failure: gates computed for the wrong principal (privilege error), tasks stranded in-progress after heartbeats (resume miss), serialization contract violated (reverse guard), stale sessions after edits (watcher), and a rollback flag that doesn't actually roll back. None are caught by the feature's own happy-path tests; all were found by adversarial review or bots after implementation. The checklist converts five rounds of discovery into one design pass.
+
+## When to Apply
+
+Any feature where resolution of "who runs this" gains a new input: column/lane staffing, per-project agent defaults, delegation, impersonation, or model-override layers. Also when reviewing: grep every reader of the old identity field (`assignedAgentId`-style) and demand each is either re-keyed or argued irrelevant.
+
+## Examples
+
+- Single-flight interaction: when one memoized implementation pass serves many callers (foreach instances), a per-call mutable slot races — the pass-*initiating* caller must own the slot for the pass's lifetime (`runGraphTaskStep` stamps `graphSeamGoverningNodeId` only when it creates the memo, clears on settle).
+- Surface-matrix tests (FN-5893): mode (defer/override) × surface (custom node, execute seam, step-execute, heartbeat, missing-agent fallback) × own-settings, plus characterization tests pinning the no-binding path byte-identical (parity oracle) and a kill-switch inertness test.
+- Ambiguous composite ids: `<foreachId>#<i>:<templateNodeId>` is unparseable under any single split when ids contain the delimiters — iterate candidates and validate against the graph (`parseInstanceNodeIdCandidates`), including that the *template node* exists, not just the container.

 ### Merge Gate
-The minimal set of merge-blocking PR checks: typecheck, build, boot smoke, and a small curated core-engine suite. The gate is the only test signal that can block a PR; admission requires evidence of value, and tests never graduate into it by default. All other tests run non-blocking.
+The minimal set of merge-blocking PR checks: lint, typecheck, build, a Boot Smoke, and a small curated engine test suite. The gate is the only test signal that can block a PR; all other tests run non-blocking after merge.
+
+Gate membership is an explicit allow-list, never a glob: a test earns its slot with evidence of value and never graduates in by default. A flake inside the gate is *evicted* — its allow-list entry is removed — which deliberately requires no green run from the flaky test itself, so the gate can always be repaired while red.
+
+### Boot Smoke
+The gate's "app starts and serves" proof: the CLI answers its help command and a real server boots on a throwaway port, answers its health endpoint, and shuts down cleanly on signal. A pass requires both that the shutdown signal was actually delivered and that the exit was clean — a crash after serving is a failed boot path, not a pass.
 
 ### Deletion Ratchet
-The standing policy for flaky tests: a test observed failing without a corresponding real bug is quarantined on sight (removed from all runs, not retried, not patched), then deleted after 2 weeks unless rescued with evidence it catches real regressions. Rescue means fixing the flake at the root; appeasement (widened timeouts, added retries, loosened assertions) is prohibited, for agents especially.

+
+A second quarantine in the same subsystem is a product-race smell: the flake may be a real bug, so the product code gets a look before the deletion clock runs out. Gate flakes exit by Merge Gate eviction rather than quarantine, unless they should also leave the non-blocking tier.

+# Thin trusted merge gate with a flaky-test deletion ratchet
+
+## Context
+
+The PR test gate had undergone trust collapse: 9 required CI checks (4 duration-balanced test shards at 4–10 min each, an engine slow tier, a dashboard inventory guard) failed mostly for flaky/infra reasons. ~70% of maintainer shipping time went to an agent-fix-and-rerun loop, and no recalled PR test failure had ever caught a real user-facing bug — the gate was pure cost. Worse, agents "stabilized" flakes by widening timeouts and adding retries, draining each test's remaining signal (the suite rotted from the inside). A separate incident compounded the distrust: the fn TUI was SIGKILLing all vitest processes on a broken memory metric, producing silent exit-137 deaths misread as flakiness/OOM (auto memory [claude]). Locally, `pnpm test` escalated to an implicit full recursive run on any shared-infra change — the dev-machine OOM path.
+
+Shipped in Runfusion/Fusion#1453 (origin: `docs/brainstorms/2026-06-04-fast-trusted-test-gate-requirements.md`, plan: `docs/plans/2026-06-04-001-refactor-fast-trusted-test-gate-plan.md`).
+
+## Guidance
+
+The pattern: **thin trusted gate on PRs + demoted non-blocking tier on main + deletion ratchet as written policy**.
+
+**1. Block PRs on a minimal trusted set, and pin that set with a test.** PRs block on exactly Lint, Typecheck, Build, Gate (`.github/workflows/pr-checks.yml`). The CI-shape test (`packages/cli/src/__tests__/ci-workflow.test.ts`) — itself part of the gate — makes drift fail loudly:
+
+```typescript
+it("blocks PRs on exactly lint, typecheck, build, and gate", () => {
+  expect(Object.keys(workflow.jobs ?? {}).sort()).toEqual(["build", "gate", "lint", "typecheck"]);
+});
+```
+
+**2. The Gate job = boot smoke + curated allow-list suite.** The boot smoke (`scripts/boot-smoke.mjs`) proves the app actually starts: CLI answers `--help`, a real `fn serve` returns `/api/health` 200 on an ephemeral port (isolated `$HOME`), and shutdown is SIGTERM-verified. The test half is `pnpm test:gate`: a curated `engine-core` vitest project (`packages/engine/vitest.config.ts`) whose membership is an **explicit file-by-file allow-list, not a glob** — 20 files, ~4s wall, ~1,025 tests, selected from committed per-file timing data (`scripts/test-timings.json`) with a determinism criterion (no real-git contention suites, no `*.slow.test.ts`, no shared-state bleed).
+
+**3. Demote everything else to a separate non-blocking workflow.** `full-suite.yml` runs the shards/slow tier/inventory guard on push to main only — a red run there is information, never a merge stopper. A separate workflow file (not `continue-on-error` jobs) keeps a red full-suite run from painting the gate's workflow red. Key the concurrency group by SHA:
+
+```yaml
+concurrency:
+  group: full-suite-${{ github.sha }}   # ref-keyed + cancel-in-progress would let
+  cancel-in-progress: false             # consecutive merges cancel each other's coverage
+```
+
+**4. The deletion ratchet is policy with minimal mechanics.** A test that fails without a corresponding real bug is quarantined on sight: a dated entry in `scripts/lib/test-quarantine.json` (`file`, `reason` + failing-run link, `quarantinedAt`) plus a hand-maintained `exclude` line in that package's vitest config, same commit. The entry expires in 14 days — then the test is deleted unless rescued with evidence it catches real regressions plus a root-cause fix. There is deliberately no loader module and no automation; `check-test-inventory.mjs --diff` stays unwired because a snapshot diff guard would fail on exactly the deletions the ratchet performs. Appeasement (timeouts/retries/loosened assertions) is banned outright in `AGENTS.md` — for agents especially.
+
+**5. Remove implicit full-suite escalation from the local default.** `scripts/test-changed.mjs` routes every ambiguous condition to gate mode instead of an implicit full run:
+
+```javascript
+if (!comparisonBase) return { mode: "gate", reason: "missing-comparison-base" };
+if (!changedFiles) return { mode: "gate", reason: "diff-failed" };
+if (changedFiles.length === 0) return { mode: "gate", reason: "no-changes" };
+if (isSharedInfraChange(changedFiles)) return { mode: "gate", reason: "shared-infra-changed" };
+```
+
+The full suite runs only on explicit opt-in (`--full` / `pnpm test:full`). In changed mode the gate suite runs first, under the isolation guard.
+
+## Why This Matters
+
+- **Red means real.** A gate with a high false-positive rate teaches everyone that red is noise. A gate small enough to curate and cheap enough to evict from restores the only property a merge gate needs.
+- **The allow-list solves the eviction chicken-and-egg.** Under a glob, removing a flaky gate test needs a PR that passes the flaky gate. Under an allow-list, eviction is deleting one line — the eviction PR never waits on the flaky test.
+- **Policy beats machinery.** This repo's history answered test pain with more test machinery (sharding, isolation checks, lock runners, kill guards). The ratchet is a written rule plus a dated JSON record; automation would let entries accumulate silently.
+- **Appeasement is how suites rot.** The ratchet leaves exactly two exits for a flake: deletion or a root-cause rescue. There is no "stabilize it" option — the prior suite was the proof of where that leads.
+- **The blind spot is documented, not hidden.** The gate does not run the union suite a merge creates; logic regressions outside the curated set land non-blocking by design (`docs/testing.md`). Stating this honestly beats the illusion of coverage that 9 untrusted jobs provided.
+
+## When to Apply
+
+- Trust collapse indicators (see `applies_when`): flake-dominated reds, zero recalled catches, appeasement loops, fix-and-rerun dominating shipping time, reflexive dismissal of red CI.
+- When eviction must be cheap: an explicit allow-list is the right gate shape even for small suites — one flaky gate test poisons the gate for everyone.
+- **Counter-case:** a repeatedly "stabilized" flake can be a real product race — see `../ui-bugs/skill-autocomplete-highlight-reset-on-swr-revalidation.md` (a flake "fixed" three times that was a genuine race). The complete triage tree: root cause known → fix the invariant; root cause unknown and no real bug → quarantine → deletion clock; second quarantine in the same subsystem → product-race smell, look before deleting.
+
+## Examples
+
+Before/after CI topology:
+
+```
+Before: PR → lint/typecheck/build + 4 test shards (4–10 min, flaky) + slow tier + inventory guard
+After:  PR → Lint, Typecheck, Build, Gate (boot smoke + ~4s curated suite)   [blocking]
+        main push → full-suite.yml: shards + slow tier + guard               [non-blocking]
+```
+
+Operational gotchas discovered while shipping this:
+
+- **A PR in `CONFLICTING` mergeable state runs zero GitHub Actions.** No `pull_request` workflows fire because GitHub cannot build the merge ref — it looks exactly like "CI never started" (no pending checks at all). Fix: merge the base branch; the resulting push triggers normally.
+- **Deleting a workflow file crashes tests that `readFileSync` it.** The asserting test fails at `beforeAll`, taking its whole file with it. Rewrite the test in the same PR and convert the absence into an invariant: `expect(() => loadWorkflow("ci.yml")).toThrow()`.
+- **Node does not fire `'exit'` on SIGTERM/SIGINT.** A smoke script registering only `process.on("exit", cleanup)` orphans its server child when the CI job is cancelled. Register explicit signal handlers that call cleanup and re-exit with 143/130.
+- **A new "always run" mode must be excluded from cache fast paths.** Gate mode initially fell into `test-changed.mjs`'s cache-fresh short-circuit and silently no-opped; the fix treats gate mode as always having work.
+- **Smoke-test shutdown verdicts need both halves:** SIGTERM actually delivered AND a clean exit (`code 0`/`SIGTERM`) — otherwise a server that crashes after the health check still prints PASS.

Parsing failures fail closed to a routable `outcome:parse-error` rather than crashing. A parse-steps node must dominate (precede on all paths) any `foreach(source:"task-steps")`, and running one after a foreach has already expanded trips pin protection (an audited failure) so re-plan loops cannot desynchronize an expanded region.

 ### Custom task field
 A workflow-declared, typed task field (`string | text | number | boolean | enum | multi-enum | date | url`, with enum options and render hints) whose values live in `tasks.customFields`, keyed by field id. The task model is thereby recast as core fields (title, description) + standard metadata + these workflow-defined fields. Writes pass through a single store authority (`updateTaskCustomFields`) that validates each value against the resolving workflow's schema and returns typed rejections (offending `fieldId` + `code`); agents write them via `fn_task_update`'s `custom_fields` patch. Editing a workflow's fields or switching a task's workflow orphans (never destroys) values for removed or type-incompatible ids — orphans are retained and surfaced under a detail disclosure, excluded from cards. Same id means the same field within a project; there is no cross-workflow shared field namespace.

+### Schema-Version Sweep
+The named process performed atomically with any bump of the core schema-version counter: a repo-wide hunt for hard-coded assertions of the old version number, updated in the same commit as the bump. The sweep's scope is every workspace that can embed the core database — packages *and* plugins — because any package instantiating the core store observes the current version; scoping the hunt to one workspace silently strands assertions in the others. Downstream consumers should prefer asserting against the exported version constant instead of a literal, which removes them from the sweep entirely.

+# Schema-version literal sweep must include plugin workspaces
+
+## Problem
+
+When `packages/core`'s `SCHEMA_VERSION` was bumped 108 → 109 (adding the `workflow_settings` table), the established "broad literal sweep" — `grep -rn 'toBe(108)' packages/` — was executed correctly and updated ~40 assertion sites. CI still failed: `plugins/fusion-plugin-roadmap` has a store test asserting `getSchemaVersion()` against a hard-coded literal, and `plugins/` lives outside the sweep's grep scope.
+
+## Symptoms
+
+```
+FAIL plugins/fusion-plugin-roadmap/src/store/__tests__/roadmap-store.test.ts
+  RoadmapStore > schema version > schema version is 108 after init
+    AssertionError: expected 109 to be 108
+```
+
+- CI shard 4/4 red on the first run after the bump landed; all `packages/` suites green.
+- Invisible locally: the plan's execution note and pre-push verification both scoped to `packages/`, and the roadmap plugin's suite is not part of a `packages/`-only vitest run.
+
+## What Didn't Work
+
+- **Following the documented sweep convention diligently.** After the bump, `grep -rn 'toBe(108)' packages/` returned zero hits — the sweep *looked* complete. The gap was scope, not carefulness: at least two plan cycles (step-inversion v108, workflow-settings v109) codified the sweep as `packages/`-scoped, an assumption that silently became false when `fusion-plugin-roadmap` grew a store layer on `@fusion/core`'s `Database` and added a schema-version pinning test.
+
+## Solution
+
+One-line fix in `plugins/fusion-plugin-roadmap/src/store/__tests__/roadmap-store.test.ts`:
+
+```ts
+// Before (failing)
+it("schema version is 108 after init", () => {
+  expect(db.getSchemaVersion()).toBe(108);
+});
+
+// After
+it("schema version is 109 after init", () => {
+  expect(db.getSchemaVersion()).toBe(109);
+});
+```
+
+The durable fix is the corrected sweep command — run at the **repo root**, not `packages/`, whenever `SCHEMA_VERSION` changes (substitute the old version):
+
+```sh
+grep -rn --exclude-dir=node_modules 'toBe(108)' .
+```
+
+## Why This Works
+
+`SCHEMA_VERSION` in `packages/core/src/db.ts` is the authoritative migration counter. Any workspace that instantiates `@fusion/core`'s `Database` runs all migrations on `init()` and therefore observes the current version — including plugin workspaces. `pnpm-workspace.yaml` globs both `packages/*` and `plugins/*` (plus named plugin dirs); schema-version assertions can live in any of them. The sweep convention predated plugin store layers, so its `packages/` scope was stale, not wrong-by-construction.
+
+## Prevention
+
+- **Sweep the whole repo, not `packages/`.** Canonical command for a bump old → new: `grep -rn --exclude-dir=node_modules 'toBe(<OLD>)' .` — the workspace globs in `pnpm-workspace.yaml` are the authoritative list of places assertions can hide.
+- **Prefer the import over the literal.** `SCHEMA_VERSION` is a named export of `@fusion/core`; plugin store tests should pin against it instead of a number, which survives every future bump with no sweep at all:
+
+  ```ts
+  import { SCHEMA_VERSION } from "@fusion/core";
+
+  it("schema version matches core after init", () => {
+    expect(db.getSchemaVersion()).toBe(SCHEMA_VERSION);
+  });
+  ```
+
+  (Core's own migration tests legitimately keep literals — they pin specific forward-path versions. The import pattern is for *downstream* consumers that just track core.)
+- **As of 2026-06-05**, `fusion-plugin-roadmap` is the only plugin with a live `getSchemaVersion()` assertion, but any plugin adding a store layer backed by core's `Database` becomes a candidate. CI shards do run `plugins/` suites, so CI is the backstop — the sweep exists to catch it pre-push.
+
+## Related Issues
+
+- [[bundled-plugin-registration-drift]] (`docs/solutions/integration-issues/bundled-plugin-registration-drift.md`) — companion failure class: an operation scoped to `packages/` silently missing the `plugins/` workspace peer. Its `packages/`-scoped grep example is correct *for its own domain* (registration points live in `packages/`); do not read it as endorsing `packages/`-only scope for schema sweeps.
+- `docs/solutions/architecture-patterns/i18n-foundation-vite-ink-monorepo-code-split-catalogs.md` — shared principle: eliminate the hardcoded second source of truth in favor of the derived/imported value.
