A single ACP-client integration unlocks **every** ACP-compatible agent — Gemini CLI, the Claude Code ACP adapter, and any future agent that speaks the protocol — through one well-specified surface instead of N bespoke ones. This is the highest-leverage expression of the "ecosystem breadth" and "neutral by design" tracks. + +Two facts from research make this a distinct shape from the existing integrations: + +1. Every current integration is **one-shot / request-scoped** (write one NDJSON turn, read stdout, force-kill). ACP is a **persistent, bidirectional JSON-RPC peer** over stdio: the agent calls *back into the client* mid-turn (permission prompts, filesystem reads). The transport core is genuinely new. +2. The official `@agentclientprotocol/sdk` (TypeScript, Apache-2.0, production-stable) provides the transport, framing, connection classes, and types — so the new work is integration and mapping, not protocol plumbing from scratch. + +This plan covers the **client** direction only (Fusion drives external agents).

A best-effort `session/cancel` + pending-permission drain runs first when teardown timing allows, but the **process-registry SIGKILL is the authoritative no-orphan / no-deadlock guarantee** — see KTD4a. +- **R6** — The plugin ships inside the published `@runfusion/fusion` CLI and is discoverable/selectable via the existing plugin-runtime resolution path (`runtimeId: "acp"`). +- **R7** — The integration is validated in CI with no API keys or network: the SDK example echo agent covers handshake + text passthrough, and a small **controllable in-repo fixture agent** deterministically exercises the security-floor paths the echo agent never reaches — `session/request_permission` (allow/deny/post-cancel), `fs/read|write`, `tool_call_*` updates, full-replace `plan` updates, and cancel-mid-prompt.

This is the resolution of the planning-time "integration shape" fork: follow the established plugin-runtime pattern for consistency and discovery (`getRuntimeById`). The dashboard `uiSlots` cards (settings/onboarding) are available via the same shape but are deferred to follow-up in v1 (see Scope Boundaries) — the runtime is selectable without them. + +- **KTD2 — Depend on `@agentclientprotocol/sdk` (Apache-2.0), API-verified at install; do not hand-roll JSON-RPC or vendor schema.** The SDK provides `ClientSideConnection`, the `Client` interface, `ndJsonStream`, the `PROTOCOL_VERSION` constant, and all request/response types tracking the canonical schema. Hand-rolling newline-delimited JSON-RPC framing or vendoring types would duplicate a maintained dependency. **Caveat:** the SDK is v0.24.0, released 2026-06-02 and not yet installed here — "stable" is an external claim, not verified locally. Pin the version and **verify the named exports at install (U1) before designing against them** — a breaking export collapses U2 and the no-plumbing premise, so it is a U1 blocker. License is compatible with the repo (MIT workspace). Per `AGENTS.md` external-integration evidence, the dependency and the agent binaries it targets must be cited in PROMPT.md. _(see external research: agentclientprotocol.com, npm `@agentclientprotocol/sdk`.)_ + +- **KTD3 — Consume the gate context Fusion already threads into every runtime; no contract change.** The ACP `Client.requestPermission` handler must answer synchronously (the agent blocks on it). The engine's canonical `AgentRuntimeOptions` (`packages/engine/src/agent-runtime.ts:35-106`) **already carries `actionGateContext?: AgentActionGateContext`** (line 103), it is **already populated per-run** at every call site via `buildActionGateContext(...)` (`executor.ts:4303/4720/3630`, `agent-heartbeat.ts:2579`, `step-session-executor.ts`), and it **already reaches the runtime** through the single funnel `createResolvedAgentSession` (`agent-session-helpers.ts:335`). `AgentActionGateContext` (`agent-action-gate.ts:30`) already bundles `permissionPolicy` plus the closures the HITL flow needs (`createApprovalRequest`, `findApprovalByDedupeKey`, `pauseForApproval`, `markApprovalCompleted`). So the ACP runtime simply **reads `options.actionGateContext`** in `createSession`, persists it on the session, and the `requestPermission` handler classifies each call via `evaluateAgentActionGate` + `resolveGateOutcome`. _(This corrects an earlier premise that the shared contract had no permission channel — it does, and `plugins/fusion-plugin-droid-runtime/src/types.ts:110` is a plugin-local structural copy the engine never imports. The discarded alternative of adding an `onPermissionRequest?` callback to the contract is unnecessary and would create a redundant second channel to the same approval store.)_ To keep the boundary clean, the plugin depends on a **narrow local `PermissionGate` interface** (the closures + policy it uses), accepting the structurally-compatible `actionGateContext` rather than importing `@fusion/engine` internals. + +- **KTD3a — Per-category gating is the v1 floor, not a deferred enhancement (security-critical).** Fusion's shipped default policy is `unrestricted` (`DEFAULT_AGENT_PERMISSION_POLICY_PRESET_ID = "unrestricted"`), which maps every action category to `allow`. A naive preset→outcome mapping would therefore auto-approve **every** tool call of an untrusted external subprocess the moment a user selects the ACP runtime without changing policy. The `requestPermission` floor (U5) must classify each `toolCall.kind` into a gate category and consult the **per-category disposition** (`permissionPolicy.rules[category]`), never the preset id: categories set to `block` reject, `require-approval` either routes to the HITL approval flow or — when no human channel is available — **default-denies**, and only categories explicitly `allow` auto-approve. ACP's `toolCall.kind` is agent-defined, optional, and partial (U4); a **missing or unmappable `kind` must map to the most-restrictive category and default-deny**, never fall through to allow — otherwise an unclassifiable call under the `unrestricted` default reopens S1. See Risk S1. + +- **KTD4 — Reuse the proven subprocess hardening conventions verbatim.** Self-cleaning process registry (`registerProcess`/`killAllProcesses` on `exit`), async non-blocking presence/auth probes (resolve timeout code `124` / ENOENT `127`), stderr buffering surfaced on non-zero exit, and a high inactivity ceiling (the engine's `StuckTaskDetector` is the authoritative aborter). `killAll` is scoped to agent subprocesses only — never the dashboard/port-4040 (per existing kill-guard conventions). + +- **KTD4a — Teardown enters via synchronous `dispose()`, not a threaded `AbortSignal`; graceful cancel is opportunistic.** The canonical `AgentRuntime` contract (`packages/engine/src/agent-runtime.ts`) carries **no** `AbortSignal`, and the engine invokes teardown as an **unawaited synchronous `session.dispose()`** (`StuckTaskDetector`, executor timeout race) plus the `process.on("exit")` registry kill — the Droid adapter's `promptWithFallback` ignores its options arg entirely. So ACP cannot rely on an `AbortSignal` arriving via `promptWithFallback`. The ACP `dispose()` issues a best-effort `session/cancel` and resolves already-pending `requestPermission` promises with `{ cancelled }` synchronously, but because `dispose()` is not awaited, the JSON-RPC notification flush and any grace window may not complete — **the real guarantee is the registry SIGKILL.** "No agent deadlock" rests on the kill, not the drain; the drain is opportunistic cleanup. The plan does not assume a graceful round-trip the engine cannot await. + +- **KTD5 — v1 passes an empty `mcpServers` at `session/new`; Fusion-custom-tool forwarding via MCP is deferred.** Keeps v1 bounded. The agent operates over its `cwd` (the task worktree). Forwarding Fusion's custom pi-tools to the ACP agent (reusing the `mcp-config.ts` + `mcp-schema-server.cjs` schema-server machinery) is follow-up work. _(Confirmed scope decision.)_ + +- **KTD6 — Filesystem client capabilities are config-gated and default to a conservative posture (security-critical).** Many ACP agents rely on client-side `fs/read_text_file` / `fs/write_text_file` when sandboxed, but granting an untrusted subprocess read+write into the worktree by default is the wrong posture. Therefore: capabilities are advertised in `initialize` **only when the resolved settings enable them** (U2 reads the toggle, never hardcodes `true`); **`writeTextFile` defaults OFF** (opt-in per agent/project); `fs/write_text_file` is treated as a `file_write_delete` action-gate category (subject to the same permission policy as U5), not a free capability; and path access is confined by a dedicated realpath-resolving jail (see KTD6a). Terminal capabilities (`terminal/create`, `terminal/output`, …) are deferred — see KTD6b for the trust-boundary consequence. + +- **KTD6a — Filesystem confinement uses a real symlink-resolving jail, not a string-prefix check.** `packages/core/src/project-root-guard.ts` is a `.fusion`-suffix / git-worktree string check, **not** a path jail — it must not be reused for fs confinement. A dedicated `assertPathWithinCwd` helper must: resolve the real path with `fs.realpath` (following all symlinks), verify it is within the realpath of the session `cwd`, perform the check and the open atomically (`O_NOFOLLOW` on the final component or open-then-`fstat`-validate) to close TOCTOU, reject absolute paths / NUL bytes / separator tricks, and apply a **deny-list regardless of cwd membership**: hard-reject writes to `.git/**` (esp. `.git/hooks`, `.git/config` → RCE/token surface) and deny or gate reads of secret patterns (`.env*`, `*.pem`, `*.key`, `.npmrc`, `.netrc`, `id_*`, `credentials`) that legitimately live inside the worktree. See Risk S3. + +- **KTD6b — The agent's native syscalls are NOT sandboxed in v1; state the real trust boundary.** ACP permissions (U5) and fs confinement (U7) constrain only *protocol-mediated* actions. The agent subprocess runs with Fusion's user privileges and can spawn child processes and reach the network directly (and would fall back to that if it needed the deferred `terminal/*`). v1 mitigations: `cli-spawn.ts` builds the subprocess `env` from an **allow-list**, not inherited `process.env` (strip secret-bearing vars). OS-level sandboxing of the agent process (restricted uid / seccomp / `sandbox-exec` / container) is recommended but deferred.

A missing/renamed export is a **U1 blocker**, not a late surprise in U2 — the whole "no protocol plumbing from scratch" premise (KTD2) depends on these. Then mirror `plugins/fusion-plugin-droid-runtime/src/index.ts` and `manifest.json`: runtime metadata `{ runtimeId: "acp", name: "ACP Runtime", … }`; `runtime-adapter.ts` implements the **full** `AgentRuntime` interface (`plugins/fusion-plugin-droid-runtime/src/types.ts:128`) — `createSession`, `promptWithFallback`, **`describeModel` (required — returns e.g. the agent binary name + negotiated mode)**, and `dispose` — with stubs that throw `not_implemented` until later units. `cli-spawn.ts` provides `resolveCliSettings(settings)` returning `{ binaryPath, args, env }` from plugin settings. + +**Patterns to follow:** `plugins/fusion-plugin-droid-runtime` (index, manifest, package.json, runtime-adapter shape including `describeModel`). + +**Test scenarios:** +- **SDK smoke-import:** `ClientSideConnection`, `ndJsonStream`, and `PROTOCOL_VERSION` are importable from `@agentclientprotocol/sdk` and have the expected shapes; a missing export fails the test (blocks the unit). +- Plugin module default-export is a valid `FusionPlugin`; `manifest.runtime.runtimeId === "acp"`. +- `definePlugin` does not throw at import; `runtime.factory(ctx)` returns an object conforming to `AgentRuntime` (has `id`, `name`, `createSession`, `promptWithFallback`, **`describeModel`**). +- `resolveCliSettings` returns defaults when given `undefined` and honors an explicit `binaryPath`/`args` override. +- Test expectation for stubs: `createSession`/`promptWithFallback` reject with a recognizable `not_implemented` marker (placeholder until U3). + +--- + +### U2.

Wrap Node streams via `Writable.toWeb`/`Readable.toWeb` for `ndJsonStream`. Send `initialize{ protocolVersion: PROTOCOL_VERSION, clientCapabilities: { fs: } }` where the `fs` capability flags are **read from resolved settings, never hardcoded `true`** — advertise `readTextFile`/`writeTextFile` only when enabled, and only because the U7 handlers exist (KTD6). Compare the agent's returned integer `protocolVersion`; if unsupported, close and surface a typed error (do not assume the agent errors first). Guard `initialize()` with a timeout (research notes Gemini-on-macOS and Claude-adapter stalls). For `authMethods` requiring interactive credentials, surface to the user rather than auto-supplying from ambient env; the auth handler must **not** read credentials from `process.env` (the env allow-list strips the *subprocess* env, not Fusion's own handler), credentials collected interactively are held **in-memory for the session lifetime only** (never written to disk), and **tokens/auth payloads are redacted from the stderr buffer and logs** (KTD4's stderr-on-failure surfacing would otherwise leak auth errors verbatim — Risk S8). If no interactive auth surface exists in v1, reject with a descriptive error rather than building an undeclared UI. Process registry self-cleans on `proc.on("exit")`; `process.on("exit", killAllProcesses)` registered in `index.ts`. Teardown is registry-SIGKILL-authoritative with best-effort `session/cancel` (KTD4a); the registry kill is what removes the process, not the cancel round-trip. Idle ceiling high (engine is authoritative aborter). Probe failure taxonomy: missing binary (`127`), handshake timeout (`124`), incompatible protocol version, unauthenticated. + +**Execution note:** Start with a failing integration test driving the SDK example echo agent through `initialize`. + +**Patterns to follow:** `plugins/fusion-plugin-droid-runtime/src/process-manager.ts` (registry, async probes, stderr buffering, kill grace); `probe.ts` failure-taxonomy pattern; `docs/cursor-cli-contract.md`. + +**Test scenarios:** +- Happy path: spawning the example agent and sending `initialize` returns a compatible `protocolVersion` and agent capabilities. +- Version mismatch: agent returns an unsupported integer → connection closes with a typed `incompatible_protocol` error, no hang. +- `initialize` timeout: agent never responds → rejects with `handshake_timeout` within the bound; subprocess force-killed. +- Spawn failure: nonexistent binary → probe resolves `missing_binary` (`127`), never throws into the event loop. +- Abort during handshake: `dispose()` / registry teardown → subprocess SIGKILLed, registry entry removed (no `AbortSignal` dependency — KTD4a). +- Registry: two spawned agents both removed from the active set on exit; `killAllProcesses` reaps survivors and does **not** target the dashboard port. +- Capability gating: with fs settings disabled, `initialize` advertises `fs` as absent/false; with them enabled, advertises true. +- Env allow-list: a secret-bearing var present in `process.env` is **not** present in the spawned agent's environment unless explicitly allow-listed. +- Auth redaction: a simulated auth error containing a token does not appear verbatim in captured stderr/logs. + +--- + +### U3.

Persist on the session object: `sessionId`, `cwd`, and **`options.actionGateContext`** (already populated by the engine — KTD3) so the U5 permission handler and U7 fs handlers can reach the live gate and the confinement root. `promptWithFallback(session, prompt)` sends `session/prompt`, resolving the returned promise only after `stopReason` arrives (research pitfall: `session/prompt` resolves *after* all updates are delivered — drain the bridge before reporting done). Map `stopReason` (`end_turn` | `tool_calls` | `cancelled`) to terminal completion. **Teardown enters via `dispose()` (KTD4a), not an `AbortSignal`** — `dispose()` issues a best-effort `session/cancel` **notification** (fire-and-forget; no ack), drains already-pending permission promises with `{ cancelled }` synchronously, then the registry SIGKILL is the authoritative guarantee. Because the engine calls `dispose()` unawaited, treat the cancel/drain as opportunistic, not guaranteed.

Record external-integration evidence in `README.md`/PROMPT.md: ACP upstream repo (`github.com/agentclientprotocol`), docs homepage (`agentclientprotocol.com`), the SDK release (`@agentclientprotocol/sdk` on npm), and the validation agent binary name (the SDK example agent) with a checksum or `upstream-pending-verification` marker — never invented. + +**Execution note:** External-integration evidence is a blocking `AGENTS.md` requirement — populate it from verified sources, never fabricated URLs/binaries/hashes. + +**Patterns to follow:** `plugins/fusion-plugin-droid-runtime` packaging; `packages/cli/src/commands/plugin.ts` `BUILTIN_PLUGINS`; `docs/cursor-cli-contract.md`; `.changeset/*.md` format. + +**Test scenarios:** +- Bundle test: a built CLI includes `dist/plugins/fusion-plugin-acp-runtime/` and it resolves via `getRuntimeById("acp")`. +- Install-path test: the `BUILTIN_PLUGINS` catalog entry is present (`experimental: true`) so the runtime is installable on demand. +- Default-policy safety: selecting the ACP runtime without an explicit policy acknowledgement does **not** silently run under `unrestricted` — the acknowledgement gate or `approval-required` default applies. _(Covers Risk S1.)_ +- Changeset present and targets `@runfusion/fusion` only (not the private `@fusion/*` packages). +- Test expectation: none for the `docs/acp-contract.md` / README evidence (documentation) — beyond a presence check in the integration-evidence lint if one exists. + +--- + +## Scope Boundaries + +### In scope +- ACP **client** integration: drive external ACP agents (U1–U8). +- Generic validation against the SDK example agent. +- Per-category permission gating (consuming the engine's existing `actionGateContext`) with HITL approval and default-deny floor. +- `fs/read|write` client capabilities behind a realpath path-jail, writes default-OFF and policy-gated. +- Untrusted-input bounds and sanitization. + +### Deferred to Follow-Up Work +- **Forwarding Fusion's custom tools to ACP agents via MCP** (`session/new` `mcpServers` populated from Fusion's pi-tools using the `mcp-config.ts` + `mcp-schema-server.cjs` schema-server machinery). v1 sends empty `mcpServers`. _(Confirmed deferral.)_ **Capability caveat:** v1 ACP agents operate over the worktree (code work via their own tools + the gated `fs` capabilities) but cannot reach Fusion's orchestration pi-tools — they reach feature parity with the bespoke runtimes only once this lands. **Security precondition for lifting the deferral:** before forwarding any `mcpServers` to the untrusted agent, define whether server configs may carry bearer tokens/OAuth credentials (and, if so, a scope-limited credential mechanism), a minimum-fields-forwarded principle, and failure behavior for an unavailable/malicious MCP server. +- **Terminal client capabilities** (`terminal/create`, `terminal/output`, `terminal/wait_for_exit`, `terminal/kill`, `terminal/release`). +- **Dashboard `uiSlots` cards** (settings/onboarding/recommendation) mirroring Droid. v1 ships the runtime selectable without dashboard cards; the cards are polish. +- **A multi-agent ACP registry** (declaring several ACP agents as `customProviders` entries via `packages/engine/src/custom-providers.ts` + `customProviderRegistryKey`). v1 follows the single-runtime `definePlugin` shape; a per-agent registry is a later extension. +- **Capturing a `docs/solutions/`-style learning** documenting the first persistent bidirectional JSON-RPC transport in the codebase, once it lands. + +### Outside this product's identity +- **The ACP *server*/agent direction** — Fusion exposing itself as an ACP agent so external editors (Zed, JetBrains) drive Fusion. This inverts the orchestration model and is a separate initiative. + +--- + +## System-Wide Impact + +- **No shared-contract change.** The permission integration consumes the engine's **existing** `AgentRuntimeOptions.actionGateContext` (`packages/engine/src/agent-runtime.ts:103`), already populated at every run call site and already funneled to runtimes via `createResolvedAgentSession` (`agent-session-helpers.ts:335`). No other runtime (Droid, Cursor, Hermes, OpenClaw, Paperclip) is touched, and `AgentRuntimeOptions` is not modified — so the earlier "touches every runtime" risk does not apply. The plugin couples only to a narrow local `PermissionGate` interface, not `@fusion/engine` internals. +- **Registration lists that must be edited (not auto-discovered).** Shipping a runtime plugin requires explicit entries beyond the workspace glob: `RUNTIME_PLUGIN_IDS` in `packages/cli/tsup.config.ts` (bundling), the chosen install list (`BUILTIN_PLUGINS` in `packages/cli/src/commands/plugin.ts`, or `BUNDLED_PLUGIN_IDS` in `bundled-plugin-install.ts` + `packages/dashboard/src/routes.ts`), and optionally `BUNDLED_PLUGIN_RUNTIMES` for pre-install dashboard visibility. Enumerated in U8. +- **New trust boundary.** This is the first integration that runs an **untrusted external subprocess that calls back into Fusion** (permissions, filesystem). The security floor (U5 per-category gate, U6 input bounds, U7 path jail, KTD6b env allow-list) is load-bearing, not polish — see Risks S1–S7. +- **Deliberate adoption-vs-safety bet.** ACP is positioned as the highest-leverage move for the strategy's "ecosystem breadth" track, yet v1 ships **experimental / on-demand** (U8) — a discovery barrier that suppresses the very metric (unique plugins active per user) the integration exists to move. This is an intentional security-first bet for v1: validate the trust-boundary floor against the SDK example agent plus one real agent, then promote ACP to a more discoverable install posture. The trigger and owner for that promotion are a follow-up decision, not a v1 deliverable. + +--- + +## Risks & Dependencies + +- **S1 — Default `unrestricted` policy → auto-allow of an untrusted subprocess [CRITICAL].** Fusion's shipped default is `unrestricted` (allow-all). A preset-level permission mapping would auto-approve every tool call the moment a user selects the ACP runtime. _Mitigation:_ U5 classifies **per call** via `evaluateAgentActionGate` and honors `rules[category]`, never the preset id; `require-approval` with no human channel **default-denies** (KTD3a). Recommend the dashboard default the ACP runtime to `approval-required`, or gate selection behind an explicit policy acknowledgement. +- **S2 — `allow_always` persists a blanket grant inside the agent [HIGH].** Selecting an `*_always` ACP option delegates the policy decision to untrusted code and loses Fusion's per-call interception. _Mitigation:_ U5 selects `allow_once`/`reject_once` only; an absent `*_once` option falls back to reject, never `*_always`. +- **S3 — Filesystem path-confinement bypass [HIGH].** Symlink escape, TOCTOU, and secrets/git-internals inside `cwd` defeat a naive prefix check; `project-root-guard.ts` is not a jail. _Mitigation:_ U7/KTD6a realpath jail + atomic open + `.git`/secrets deny-list, with symlink-escape and `.git/hooks` tests. +- **S4 — fs capabilities default-ON would over-grant [HIGH].** _Mitigation:_ KTD6 — writes default OFF, advertisement config-gated, `fs/write` routed through the action gate as `file_write_delete`. +- **S5 — Unbounded agent output / oversized fs content [MEDIUM].** The high inactivity ceiling does not bound an *actively* flooding agent. _Mitigation:_ U6 caps `session/update` volume; U7 caps read/write byte sizes. +- **S6 — Agent native syscalls are unmediated [MEDIUM].** ACP permissions + fs jail constrain only protocol-mediated actions; the agent can spawn processes / reach the network directly. _Mitigation:_ KTD6b — env allow-list in `cli-spawn.ts`; document the real trust boundary; OS-level sandboxing recommended (deferred). +- **S7 — Untrusted agent strings (titles, ids, paths) [MEDIUM].** Log/ANSI injection; ids used as map/path keys. _Mitigation:_ U6 sanitizes control/ANSI sequences and validates ids before any filesystem use. +- **S8 — `authenticate` credential handling [LOW-MED].** _Mitigation:_ U2 surfaces interactive auth to the user, redacts tokens from stderr/logs. +- **External dependency maturity.** `@agentclientprotocol/sdk` is young (v0.24.x). _Mitigation:_ pin the version; protocol version is a stable integer (`1`); validate against the SDK's example agent so CI needs no third-party binaries. +- **Cancellation/permission deadlock.** An unanswered in-flight `requestPermission` after `session/cancel` hangs the agent. _Mitigation:_ explicit pending-request drain (U5), test-covered. +- **Agent-specific startup quirks.** Gemini-on-macOS OAuth prompts; Claude-adapter `session/new` stalls. _Mitigation:_ bounded `initialize`/`session/new` timeouts + typed failure taxonomy (U2). +- **Streaming ordering.** `session/prompt` resolves only after all updates are delivered; plan updates are full-replace. _Mitigation:_ drain-before-done (U3), replace-not-append (U4), test-covered. +- **Packaging/bundle drift.** A plugin missing from `RUNTIME_PLUGIN_IDS` is silently never bundled. _Mitigation:_ the U8 bundle-output test asserts the plugin's presence in `dist/plugins/`. + +--- + +## Alternatives Considered + +- **Hand-roll the JSON-RPC transport instead of using the SDK.** Rejected (KTD2): duplicates a maintained dependency, and the newline-delimited framing + bidirectional call handling is exactly what the SDK's `ClientSideConnection`/`ndJsonStream` provide. Revisit only if the SDK proves unmaintained. +- **Build as a `packages/acp-cli` package mirroring `pi-claude-cli`.** Rejected (KTD1): that pattern is now a thin shim; the runtime-plugin shape is canonical and gives discovery + dashboard parity for free. +- **Per-agent provider registration (one provider id per ACP agent) up front.** Deferred: a single `runtimeId: "acp"` runtime is enough for v1; a multi-agent registry via `customProviders` is the natural follow-up if users need several ACP agents side by side. +- **Add an `onPermissionRequest?` callback to the shared `AgentRuntimeOptions` contract.** Rejected (KTD3): the contract **already** carries `actionGateContext`, already populated and threaded to runtimes — a new callback would be a redundant second channel to the same approval store and would needlessly touch the interface every runtime consumes. The ACP plugin consumes the existing field instead. +- **Pass the gate via the plugin runtime factory `ctx`.** Rejected: `PluginContext` is built once *per plugin*, not per run; the gate context is per-run/per-session. Threading it through `ctx` is a lifetime/scope mismatch. Per-session `options.actionGateContext` is the correct vehicle. +- **Preset-level permission mapping (map the policy preset directly to an ACP outcome).** Rejected (KTD3a / Risk S1): the default preset is `unrestricted`, so this silently auto-allows an untrusted subprocess and ignores per-category `block` rules. Per-call category classification is the v1 floor, not a deferred enhancement. + +--- + +## Sources & Research + +- **ACP protocol & SDK** (external, load-bearing for KTD2/KTD5/KTD6 and U2–U5): agentclientprotocol.com (introduction, schema, transports, initialization, tool-calls, agent-plan); `@agentclientprotocol/sdk` (npm, Apache-2.0, `ClientSideConnection`, `ndJsonStream`, `PROTOCOL_VERSION`); `github.com/agentclientprotocol/typescript-sdk`; validation agents — SDK example echo agent (CI), `@agentclientprotocol/claude-agent-acp` and `gemini --acp` (manual e2e). +- **Repo patterns** (local): `plugins/fusion-plugin-droid-runtime/` (canonical runtime-plugin shape, module split, `uiSlots`); `plugins/fusion-plugin-cursor-runtime/`; `packages/engine/src/runtime-resolution.ts` (`getRuntimeById`, factory wrapping); `plugins/fusion-plugin-droid-runtime/src/types.ts:110-135` (`AgentRuntime`/`AgentRuntimeOptions`); `packages/engine/src/agent-action-gate.ts`, `packages/core/src/agent-permission-policy.ts`, `packages/core/src/approval-request-store.ts` (permission/approval surfaces); `packages/cli/tsup.config.ts` + `packages/cli/package.json` `files` (bundling); `docs/cursor-cli-contract.md`, `docs/PLUGIN_AUTHORING.md` §9, `docs/spawn-agent-approval-evaluation.md`. +- **Conventions** (`AGENTS.md`): external-integration evidence (R8/U8), changeset rules (`@runfusion/fusion: minor`), publish/bundle model, sibling `__tests__/` test layout. diff --git a/docs/plans/2026-06-03-001-feat-branch-group-single-pr-flow-plan.md b/docs/plans/2026-06-03-001-feat-branch-group-single-pr-flow-plan.md new file mode 100644 index 0000000000..f0a23740df --- /dev/null +++ b/docs/plans/2026-06-03-001-feat-branch-group-single-pr-flow-plan.md @@ -0,0 +1,363 @@ +--- +title: "feat: End-to-end branch-group single managed PR flow (planning + missions)" +type: feat +status: completed +date: 2026-06-03 +depth: deep +--- + +# feat: End-to-end branch-group single managed PR flow (planning + missions) + +## Summary + +When a user runs **planning** or a **mission**, every task in the resulting group should land on one shared group branch, and that group branch should produce **a single PR that is created and kept in sync** as members land — through to a terminal merge/close. + +The plumbing for most of this already exists (the FN-5782 → FN-5788 → FN-5819 → FN-5830 → FN-5846 chain).

There is no "PR" beyond a status string. + +2. **The manual promote route is dead.** `POST /branch-groups/:id/promote` (`packages/dashboard/src/routes/register-branch-groups-routes.ts`) invokes `engine.promoteBranchGroup(groupId)` as a method on the engine object, but only a standalone function exists. The dashboard test mocks the method, so the gap is invisible in CI. + +3. **Members can't be enumerated by group.** Planning and missions stamp `task.branchContext.groupId` with a synthetic string (`planning:` / `mission:`), while the stored `BranchGroup.id` is a generated `BG-…`. `listTasksByBranchGroup(group.id)` filters on exact `groupId` equality, so auto-created groups won't list their members — which breaks completion gating and PR rollup. + +4. **Inconsistent "landed" semantics.** The route's `isMemberLanded` and the coordinator's `evaluateBranchGroupCompletion` define "landed/complete" differently, so the gate that reveals PR controls can disagree with the gate the engine uses to promote. + +Underlying all of this is a **data-loss risk** (the 2026-05-23 lost-work incident): shared members share branch lineage, so any path that resolves a shared member's merge target to a sibling `fusion/fn-*` branch or to `main` instead of `branch_groups.branchName` can strand or mis-attribute work.

This is the smallest change that makes membership queries correct everywhere and avoids a dual-key convention that would rot. Migration concern for already-created groups is addressed in U1. +- **KTD2 — One canonical landed/completion predicate in `@fusion/core`.** Extract a single function (e.g. in `packages/core/src/task-merge.ts` or a small `branch-group-completion.ts`) consumed by both the route and the coordinator, so the gate can never diverge again. +- **KTD3 — Build a new group-PR sync helper; do NOT reuse `refreshPrInBackground`.** Feasibility review confirmed `refreshPrInBackground` (`packages/dashboard/src/routes/register-git-github.ts:2220`) is task-hardwired and runs the *wrong direction* — it pulls review/merge status *from* GitHub onto a task's PR array; U6 needs to *push* an updated PR **body** for a group PR stored on the `branch_groups` row. `github.ts` has `mergePr` but no `updatePr`/`closePr` helper, so those are net-new. The `(source, externalId)` idempotency key belongs to the comment-import path (`register-git-github.ts:2073`), is unrelated to group-PR sync, and must not be cited as the dedup mechanism here. +- **KTD4 — Promotion/sync idempotency via persisted `prNumber` + `getBranchGroupByBranchName`** (`packages/core/src/store.ts:4373`). Before creating a PR, check for an existing one on the group; create only when absent. Re-running promotion is a no-op on the PR. This — not KTD3 — is the load-bearing idempotency guarantee for R5/R6. +- **KTD5 — A single engine bridge method** (`engine.promoteBranchGroup(groupId)`) wraps the standalone coordinator function so the route wiring in `register-integrated-routers.ts` works and the dashboard test stops mocking a non-existent method. +- **KTD7 — Inject the GitHub client via the existing `processPullRequestMerge` option seam, not `setCreateFnAgent`.** The engine already receives GitHub capability as a constructor-option callback that closes over a dashboard-built `GitHubClient` (`packages/engine/src/project-engine.ts:207`, invoked at `:1877`; constructed in the CLI layer at `daemon.ts:335`, `dashboard.ts:1560`, `serve.ts:361`). Add a sibling option (e.g. `promoteBranchGroupPr`/`createGroupPr`) alongside it and thread it through **all three** CLI construction sites. `setCreateFnAgent` is a weaker module-load global and the wrong model here. +- **KTD6 — Additive schema only.** `branch_groups` already carries `prState`/`prUrl`/`prNumber` (per `storage.md`). If a member-checklist cache is needed it's an additive, forward-only, version-gated `IF NOT EXISTS` column — no destructive backfill, `fusion-central.db` untouched.

The synthetic value never resolves against `getBranchGroup` (a plain PK lookup, `store.ts:4363`), so it is broken for *every* consumer today, not just enumeration. Fix: capture the returned `group.id` and stamp it. `setTaskBranchGroup` should carry the group's actual assignment intent instead of literal `"shared"`. A read-side fallback matching the legacy synthetic key is harmless and preserves enumeration of already-broken old groups — but note it is not preventing a regression (legacy groups were already non-functional for promotion/gating), so keep it minimal and removable. + +**Patterns to follow:** `ensureBranchGroupForSource` idempotency; existing `branchContext` shape in `types.ts` (~1690). + +**Test scenarios:** +- Covers F (planning shared group).

The two existing semantics genuinely disagree (feasibility-confirmed): the route requires `mergeConfirmed === true && mergeTargetSource === "branch-group-integration" && mergeTargetBranch === group.branchName` (`register-branch-groups-routes.ts:13`), while the coordinator accepts `column === "done"` OR `(column === "in-review" && mergeTargetSource === "branch-group-integration")` and **never checks `mergeTargetBranch`** (`group-merge-coordinator.ts:50`). **Decision:** the stricter route semantics win — landing requires `mergeConfirmed` **and** `mergeTargetBranch === group.branchName`. This is load-bearing for U3's merge-target safety guarantee (a member `done` against a sibling/mismatched branch must NOT count as landed).

Every prior agent integration (droid, cursor, hermes, openclaw, pi-claude-cli) is one-shot: write one NDJSON turn, read stdout, force-kill. ACP inverts part of the relationship — Fusion spawns the agent, but the agent **calls back into Fusion mid-turn** (`session/request_permission`, `fs/read_text_file`, `fs/write_text_file`). That makes the agent untrusted *input* on every channel, and several hard-won rules from this build will apply to any future integration with the same shape. + +## Guidance + +**1. The canonical integration shape is a runtime plugin, not a `packages/*-cli` package.** +`packages/pi-claude-cli` / `droid-cli` are legacy shims. New agent integrations live in `plugins/fusion-plugin--runtime` using `@fusion/plugin-sdk`'s `definePlugin` with a `runtime: { metadata: { runtimeId }, factory }` block, implementing the `AgentRuntime` interface (`createSession` / `promptWithFallback` / `describeModel` / `dispose`). The engine resolves it via `getRuntimeById(runtimeId)` once installed. + +**2. Engine lifecycle truths (verified against the engine, not docs):** +- The engine's `AgentRuntimeOptions` (`packages/engine/src/agent-runtime.ts`) **already carries `actionGateContext`** — populated at every run call site and funneled through `createResolvedAgentSession`. Consume it **structurally** via a narrow plugin-local interface; never import `@fusion/engine` and never add a parallel permission channel to the shared contract. +- There is **no `AbortSignal`** in the runtime contract. Teardown enters via an **unawaited synchronous `dispose()`** (StuckTaskDetector, executor timeout) plus the process-registry kill. Design teardown so the registry SIGKILL is the authoritative no-orphan/no-deadlock guarantee; any graceful protocol cancel (`session/cancel` + pending-request drain) is opportunistic. Register `process.on("exit", killAllProcesses)`. +- Bundling is **not automatic**: a new runtime plugin must be added to `RUNTIME_PLUGIN_IDS` in `packages/cli/tsup.config.ts` (or it silently never ships) and to an install list (`BUILTIN_PLUGINS` for on-demand, `BUNDLED_PLUGIN_IDS` for auto-install), plus `pnpm-workspace.yaml`. + +**3. Security floor for an untrusted callback-capable subprocess:** +- **Per-category permission gating, never per-preset.** The shipped default policy preset is `unrestricted` (every category → allow). A preset-level shortcut auto-approves everything the moment the runtime is selected. Classify each call's kind into a category and read `permissionPolicy.rules[category]`; add an explicit acknowledgement setting before honoring blanket allows on sensitive categories. +- Select `allow_once` only — never `allow_always`/`reject_always` (a persisted grant inside untrusted code loses per-call interception). Unmappable/missing kinds, missing gate/policy, and HITL-without-a-readable-decision all default-deny. Require **both** `pauseForApproval` AND `findApprovalByDedupeKey` before creating an approval request — otherwise a human approval is silently discarded and a pending record is orphaned. +- **Filesystem jail = realpath, not string checks.** `project-root-guard.ts` is a suffix check, not a jail. Use realpath-within-realpath(cwd), `lstat` the final component for new files, `O_NOFOLLOW` open, and **truncate only after post-open re-validation** (passing `O_TRUNC` into open() truncates an escaped target before validation — write-path TOCTOU). Deny-list secrets and `.git/**` by basename regardless of cwd membership. Stat-gate reads (a full `readFile` before a byte ceiling is an OOM vector). +- **Bound everything the agent emits**, including the channels that don't look like output: per-turn + per-chunk caps on text/thinking, ANSI/control stripping, bounded identifier lengths and correlation maps, and **plan/structured events** (entry size was bounded but entry *count* wasn't — 1,000 × 64KB entries bypassed the per-turn budget). Redact stderr across chunk boundaries, not per-chunk (secrets split across `data` events evade per-chunk regexes). Build the subprocess env from an allow-list, never inherited `process.env`. + +**4. Per-turn bridge state must actually reset per turn.** Anything accumulated per "turn" (output budgets, cap-flag latches, tool-call correlation maps) needs an explicit `reset()` invoked at the top of each prompt — a latch that never resets silently suppresses all output for the rest of the session after one flood. Write a two-turns-through-the-same-handler test; single-turn tests cannot catch it. + +**5. The installed SDK's types are authoritative over docs/research.** Verify a young SDK's exports with a smoke-import test at scaffold time (a missing export is a day-one blocker, not a late surprise), and read the generated `.d.ts` for shapes: research/docs said `session/update` used `content_chunk`/`tool_call_started`; the real SDK uses `agent_message_chunk`/`tool_call`/`tool_call_update`, and `plan_update` carries a `plan` field, not `entries` (the wrong-shape cast silently no-op'd). + +**6. Test fixtures for bidirectional protocols must be race-proof.** JSON-RPC notifications are dispatched concurrently with suspended request handlers. A fixture that registers a cancellable hang *after* an awaited write loses the race on loaded CI runners (cancel lands first, no-ops, prompt hangs forever). Record a pending-cancel flag so resolution is order-independent — never rely on a `setImmediate` tick for ordering. + +## Why This Matters + +The one-shot integrations never needed any of this: they hold no server→client channel, no long-lived session state, and their kill-after-turn lifecycle hides teardown bugs. A bidirectional peer fails in new ways — permission deadlocks on cancel, latched per-session state, TOCTOU in callback-served filesystem access, budget bypasses through structured events — and three of those shipped as P1s caught only by adversarial review, not by 170+ passing unit tests.

A treacherous conflict class arises when the two sides operate on the same code at different layers: one branch performs a **structural refactor** (extracts/moves a block, behavior-preserving) while main performs a **semantic change** (alters what that block does). Git presents an ordinary either/or conflict, but **both "pick a side" resolutions are wrong** — one discards the refactor, the other silently reverts the semantic change, and the second failure mode is invisible because the behavioral logic has been relocated out of git's view. + +Observed merging `main` into `gsxdsm/missonsdebug` (merge `60c307320`): the branch had extracted an inline validation block from `processTaskOutcome` into a shared helper `runFeatureValidation` (`packages/engine/src/mission-execution-loop.ts`); main's FN-5902 (`cc18206bc`) changed that same block's semantics (zero-assertion auto-pass → lazy `ensureFeatureAssertionLinked`). A docs-level variant landed in the same merge: two ce-compound runs had each bootstrapped `CONCEPTS.md` (add/add), and the incoming FN-5902 semantics falsified a glossary entry the branch had written. + +## Guidance + +**When one side refactors code and the other changes that code's behavior, keep the refactor's structure and re-apply the semantic change at the code's new location.** Git cannot do this for you. + +1. **Recognize the shape.** The tell: one conflict side is a call/one-liner, the other is a large block — the block that *used to* live there. Structure moved on one side; behavior changed on the other. +2. **Keep the call site** (preserve the refactor). +3. **Port the incoming semantic change into the helper body** at its new home — do not accept either hunk verbatim. +4. **Sweep the moved code's documentation** — a doc comment or glossary entry describing the old behavior is now a lie; fix it in the same merge. +5. **Run the merged (union) test suite + typecheck**, not just one branch's tests — the merge creates a combination neither branch tested. +6. **Name the merge commit after the adopted change** (e.g. `Merge main: adopt FN-5902 lazy assertion linkage in shared runFeatureValidation`), not a bare `merge main`. + +For **accretive docs** (`CONCEPTS.md`, glossaries, registries) hitting add/add: **merge as a union** — clusters are independent; keep one preamble. For near-identical pointer lines (e.g. `AGENTS.md` references), take the wording that minimizes the diff. Then sweep the merged prose for statements the incoming commits falsified. + +## Why This Matters + +The dangerous resolution is invisible. Keeping the branch side verbatim looks clean: + +```ts +await this.runFeatureValidation(feature); // tidy one-liner — but the helper body + // still contains the OLD auto-pass +``` + +```ts +// stale helper body — silently reverts FN-5902 +if (assertions.length === 0) { + await this.handleValidationPass(feature.id, undefined, "No assertions linked"); + return; +} +``` + +The merge diff shows **no trace** of the regression — the reverted logic lives in a region git never flagged. FN-5902 is silently undone and the diff passes review as a clean refactor. The mirror mistake (keeping main's block) drops the extraction and breaks the other call site that motivated it. + +The collision class is not hypothetical or rare here: **four parallel branches bootstrapped or substantially extended `CONCEPTS.md` on the same day, each as a full-file write rather than an append** — so every one of them will hit this add/add when merging, until they all land. + +## When to Apply + +- A merge/rebase conflict where one side is a call/delegation and the other is a multi-line block that previously lived at that spot. +- One branch moved/extracted/renamed code that the other branch changed the behavior of.

Fixed in PR #1357. + +## Symptoms + +- Shared groups never reached `complete`/`finalized` — `listTasksByBranchGroup(group.id)` returned `[]` because entry points stamped synthetic `planning:` / `mission:` strings into `branchContext.groupId` while the stored row id was a generated `BG-…`; no primary-key lookup could resolve them. +- `POST /api/branch-groups/:id/promote` threw `"promoteBranchGroup is not available on engine"` (`packages/dashboard/src/routes/register-integrated-routers.ts`) — the route invoked `engine.promoteBranchGroup(groupId)` as a method, but only a standalone coordinator function existed. +- `prState: "open"` with `prNumber`/`prUrl` null — promotion flipped the state field without performing the side effect, so dashboards *looked* correct. +- The route's `isMemberLanded` required `mergeConfirmed` + matching `mergeTargetBranch`; the coordinator's `evaluateBranchGroupCompletion` accepted bare `column === "done"` and never checked the branch — the two gates could disagree, and a member merged onto a sibling branch could count as "landed" (the failure class behind the 2026-05-23 lost-work incident). + +## What Didn't Work + +- **Trusting the green test suite.** `routes-branch-groups.test.ts` mocked the missing engine method with `vi.fn(async () => ({ prNumber: 202, ... }))` and asserted the mock was called — fabricating an API that never existed on `ProjectEngine`. The test passed; production threw. +- **Reading the state fields.** `prState` was written independently of PR creation, so every read surface (dashboard, API, CLI) reported a healthy PR pipeline that did not exist. +- **Assuming the documented contract held.** `docs/missions.md` ("Shared branch-group invariant") and `docs/architecture.md` (FN-5830) describe the intended `branchContext.groupId → branch_groups` resolution and "idempotent promoteBranchGroup (single shared→default merge/PR)" — the implementation silently diverged from both until #1357. + +## Solution + +Four core fixes (commits `66ca583`…`f3bc757` on PR #1357): + +1. **Capture and stamp the real `BG-` id.** Entry points called `ensureBranchGroupForSource(...)` for its side effect and discarded the returned row. Bind it: + + ```ts + // before — return value discarded, synthetic string stamped into branchContext + this.taskStore.ensureBranchGroupForSource("mission", missionId, {...}); + // ...branchContext built with groupId: `mission:${missionId}` + + // after — bind the returned row's id + const group = this.taskStore.ensureBranchGroupForSource("mission", missionId, {...}); + missionGroupId = group.id; // the real BG- id, spread into branchContext only when a group exists + ``` + + Same pattern at both planning entry points (`register-planning-subtask-routes.ts`). Non-shared members now carry **no** `groupId` at all (it became optional) so they can't be swept into a group by the legacy fallback. + +2. **Real engine bridge method + de-mocked test.** Added `ProjectEngine.promoteBranchGroup(groupId)` delegating to the standalone coordinator (no duplicated logic). The test now guards the wiring instead of masking it: + + ```ts + expect(typeof (ProjectEngine.prototype as { promoteBranchGroup?: unknown }).promoteBranchGroup).toBe("function"); + ``` + + plus a test that binds the *real* method body to a stub context and drives the route through it. + +3. **Real PR creation via injected callbacks.** `CreateGroupPrFn` / `SyncGroupPrFn` types are defined in `packages/engine/src/group-merge-coordinator.ts` and injected from the CLI composition layer (mirroring the existing `processPullRequestMerge` DI seam) — the engine never imports the dashboard's GitHub client. The two callbacks serve different paths: `createGroupPr` runs during promotion; `syncGroupPr` runs on the separate member-landing path (and on-read reconciliation), not during the promote call. Wired at **all three** engine-construction sites (`daemon.ts`, `serve.ts`, `dashboard.ts`); missing one site gives that entry point divergent behavior. Idempotency keys on the persisted `prNumber` with open-PR-only reuse; on GitHub failure the code does **not** flip `prState` ("do NOT flip prState to a lie") — the error surfaces and idempotent re-promotion retries. + +4. **Canonical predicates in `@fusion/core`.** `isBranchGroupMemberLanded` / `isBranchGroupComplete` (`packages/core/src/branch-group-completion.ts`) are consumed by both the route and the coordinator. The stricter branch-anchored semantics won: landed iff `mergeConfirmed && mergeTargetSource === "branch-group-integration" && mergeTargetBranch === group.branchName`. + +## Why This Works + +- **Identity must be the stored row's id, not a re-derivable string.** Only `ensureBranchGroupForSource` knows the real `BG-` id; discarding its return value guarantees every downstream primary-key lookup misses. +- **Wiring must be proven by a real-method test.** A `vi.fn()` named like the method proves nothing about the method existing; asserting on the real prototype makes the wiring load-bearing. +- **State fields that mirror an external side effect must be written only by the path that performs it.** `prState: "open"` written independently of PR creation is structurally a lie. +- **Predicates shared, not duplicated.** Two copies of "is this landed?" drift; one function in core consumed by every gate cannot. + +## Prevention + +- **Never discard the return value of an `ensure*`/`create*` store method when stamping a reference.** Bind the returned row's `.id`; never reconstruct a synthetic key. +- **Before mocking an engine/service method in a test, assert it exists on the real prototype** — or better, bind the real method to a stub context and drive it. A mock of a non-existent method is a permanent false-green. +- **Only write side-effect-mirroring status fields from the code path that performs the side effect.** Never flip them speculatively "so the UI looks right." +- **Extract shared predicates to the core package** when a route and an engine make the same decision. +- **For cross-package capabilities, use the injected-callback DI seam** (define `XxxFn` types in the lower package, inject from the composition layer) and **audit every construction site together** — a capability wired at only some sites produces entry-point-dependent bugs no single test catches. + +## Related Issues + +- PR #1357 — the fix (branch `gsxdsm/taskbranch`) +- Issue #1259 (FN-5830) — the incomplete re-land of the completion gate + promotion API that this corrects; Issue #1227 (FN-5788) — the promotion-hook predecessor +- `docs/incidents/2026-05-23-lost-work-tasks.md` — same failure family (silent merge-target/landing-attribution bugs); the branch-anchored landed predicate here closes a gap from that incident +- `docs/missions.md` ("Shared branch-group invariant across entry points") and `docs/dashboard-guide.md` ("Shared branch groups", single group-level PR contract) — the intended contracts the implementation diverged from +- `docs/architecture.md` FN-5782/5788/5830/5846 block — the canonical branch-group merge-routing narrative this fix repairs +- Known follow-up: 2 pre-existing failures in `shared-branch-group-entry-points.test.ts` (per-task-derived working-branch derivation) are a separate bug, untouched by this fix (auto memory [claude]) diff --git a/docs/solutions/logic-errors/files-changed-inflated-by-origin-first-base-commit.md b/docs/solutions/logic-errors/files-changed-inflated-by-origin-first-base-commit.md new file mode 100644 index 0000000000..9fadf0110b --- /dev/null +++ b/docs/solutions/logic-errors/files-changed-inflated-by-origin-first-base-commit.md @@ -0,0 +1,101 @@ +--- +title: In-review files-changed inflated by origin-first baseCommitSha capture +date: 2026-06-03 +category: logic-errors +module: engine +problem_type: logic_error +component: development_workflow +symptoms: + - "In-review tasks showed 20-31 files changed when only 2-12 were actually touched" + - "Extra files in a task's diff belonged to other, already-merged tasks" + - "All in-review tasks in a cohort shared a suspiciously old baseCommitSha" + - "Inflation was permanent — display-time merge-base recovery could not tighten it" +root_cause: logic_error +resolution_type: code_fix +severity: medium +related_components: + - testing_framework +tags: + - git-merge-base + - basecommitsha + - fork-point + - origin-vs-local-main + - files-changed + - worktree-pool + - rebase-and-push + - diff-base +--- + +# In-review files-changed inflated by origin-first baseCommitSha capture + +## Problem + +New task branches recorded a `baseCommitSha` that was too old, so the dashboard's `baseCommitSha..HEAD` diff swept in files belonging to other, already-merged tasks — showing 20–31 "files changed" when the task actually touched 2–12 (FN-5937: 31 shown vs 12 real). `captureBaseCommitSha` computed `git merge-base HEAD origin/main` while the merger lands commits on **local** main before pushing. + +## Symptoms + +- In-review tasks on the dashboard displayed inflated "files changed" counts (20–31) versus their true touched-file count (2–12). +- The extra files all belonged to other tasks that had already merged (FN-5937's inflated diff contained files from FN-5936/FN-5907/FN-5939/FN-5940). +- The inflation was **permanent** — display-time recovery could not tighten it because the orphaned predecessor SHAs were no longer reachable from `main`. +- All in-review tasks in a dispatch cohort shared a suspiciously too-old `baseCommitSha`; the pattern recurred on the next cohort (FN-5953) after the next rebase-push cycle. + +## What Didn't Work + +- **Worktree-pool reassignment** — a recycled worktree hosting a foreign branch could surface another task's commits.

A real-git regression suite (`packages/engine/src/__tests__/base-commit-capture.real-git.test.ts`) locks the behavior in, including the local-ahead-of-origin scenario. The 5 already-corrupted live in-review tasks were repaired in place via `TaskStore.updateTask`, recomputing each base as the parent of the branch's first own-attributed commit, with ancestry safety checks.

Two consequences flow from this: + +1. At the moment a new task's base is captured (right after worktree acquisition — the worktree forks from the **local** main tip via `prepareForTask` → `resolveIntegrationBranch`), local `main` can be **ahead of `origin/main`** by merged-but-unpushed commits. Measuring `merge-base HEAD origin/main` rewinds the base past those commits. +2. The post-merge rebase-and-push rewrites those commits' SHAs in `main`, **orphaning** the originals that the task branch still descends from. Even display-time `merge-base(HEAD, main)` recovery can't find a tightening point afterward — the orphaned SHAs aren't in `main` anymore. + +``` +fork time: ...59cd9ea ── 839d191 (merged, unpushed) ── 8db04c4 ← local main tip + │ + └─ taskBranch: a1 a2 ... +captured base = merge-base(HEAD, origin/main) = 59cd9ea ← too old: includes 839d191's files + +after rebase-push: main = ...59cd9ea ── ── 419f688 (was 839d191) ── ... + taskBranch still descends from the now-orphaned 839d191/8db04c4 + merge-base(HEAD, main) = 59cd9ea → no recovery possible +diff 59cd9ea..HEAD permanently shows predecessors' files as this task's changes +``` + +**The invariant:** any base / fork-point computation in this codebase must measure against **local `main` first**, with `origin/main` only as a fallback. Because the merger lands commits locally before pushing — and the push rewrites their SHAs — `origin/main` is systematically behind, and an origin-first merge-base will rewind the base into a predecessor's history and then strand it. + +## Prevention + +- **Follow the invariant**: every base/fork-point computation uses `git merge-base HEAD main 2>/dev/null || git merge-base HEAD origin/main` (local-first).
