Built generically against the official `@agentclientprotocol/sdk` (no single reference agent), validated in CI against the SDK's example echo agent. + +--- + +## Problem Frame + +Fusion's thesis (see `STRATEGY.md`) is to be the model- and surface-agnostic orchestration layer, with a plugin ecosystem so it adapts as agents evolve. Today every agent integration is bespoke: `plugins/fusion-plugin-droid-runtime` drives the Droid CLI, `fusion-plugin-cursor-runtime` drives Cursor, `fusion-plugin-hermes-runtime`, `fusion-plugin-openclaw-runtime`, and `packages/pi-claude-cli` (now a thin shim) each hand-roll a subprocess transport, a stdout parser, and an event bridge for one specific tool. + +ACP is an open, versioned protocol (Zed Industries; protocol version `1`) that standardizes exactly this client↔agent contract. 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). The reverse direction (Fusion exposing *itself* as an ACP agent for editors like Zed) is explicitly out of scope. + +--- + +## Requirements + +- **R1** — Fusion can launch a configured ACP agent binary as a subprocess and complete the `initialize` capability handshake, including integer protocol-version negotiation and a readiness timeout. +- **R2** — Fusion can open a session (`session/new`), send a user turn (`session/prompt`), and receive the terminal `stopReason`. +- **R3** — Streaming `session/update` notifications (agent text, reasoning, tool calls, plan) are mapped onto the existing `AgentRuntime` callbacks (`onText`, `onThinking`, `onToolStart`, `onToolEnd`) so ACP agents appear in Fusion's UI/logs identically to existing runtimes. +- **R4** — The agent's `session/request_permission` requests are answered according to Fusion's agent permission policy, with correct cancellation semantics. +- **R5** — Run teardown (engine stuck-task detection / executor timeout) invokes the runtime's `dispose()` and force-kills the subprocess; no orphaned processes survive. 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. Real agents (Gemini CLI, the Claude-adapter) remain manual e2e. +- **R8** — Third-party-integration evidence (upstream repo, docs, release, binary name, checksum/marker) is recorded per `AGENTS.md`. + +**Success criteria:** a user can configure an ACP agent, assign a Fusion task/agent to `runtimeId: "acp"`, and watch the agent stream text + tool calls and honor the user's permission policy — with the same lifecycle guarantees (abort, no orphans) as the Droid/Cursor runtimes. + +--- + +## Key Technical Decisions + +- **KTD1 — Build as a runtime plugin (`plugins/fusion-plugin-acp-runtime`), not a `packages/*-cli` package.** Research confirmed the `packages/pi-claude-cli` / `droid-cli` packages are now thin compatibility shims; the canonical integration shape is a first-class plugin under `plugins/` using `@fusion/plugin-sdk`'s `definePlugin` with a `runtime` manifest + `AgentRuntime` adapter (see `plugins/fusion-plugin-droid-runtime` and `fusion-plugin-cursor-runtime`). 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.

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.

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.

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.

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.

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).

If a PR already exists for the group (persisted `prNumber` or matching open PR via `getBranchGroupByBranchName`), reuse it — never open a second (KTD4). The GitHub client reaches the coordinator via the injected `processPullRequestMerge`-style option callback (KTD7), never a static dashboard import.

On each member landing, if the group has an open PR, enqueue a body refresh (member list + completion); idempotency comes from the persisted `prNumber` (KTD4), so coalescing/retry must be built here, not inherited. On group completion/merge, set `prState=merged`; on abandon (`status=abandoned`), close the GitHub PR and set `prState=closed`. + +**Patterns to follow:** `updateBranchGroup` closing semantics; the injected-callback seam from U5 (KTD7). + +**Test scenarios:** +- Second member lands after PR open → PR body reflects 2/N; no duplicate PR. +- Group fully merged → `prState=merged`, GitHub PR merged/closed. +- Group abandoned → `prState=closed`, GitHub PR closed. +- Concurrent member landings → single coalesced refresh (idempotent), no race-duplicated updates. +- Sync failure is retryable and does not corrupt `prState`. +- Group PR closed/merged out-of-band on GitHub (persisted `prNumber` no longer open) → sync detects and reconciles `prState` rather than erroring or re-opening. + +**Verification:** PR body tracks completion as members land; terminal states reconcile both `prState` and the GitHub PR. + +--- + +### U7.

End-to-end integration tests (planning + mission) + +**Goal:** Prove the full flow for both entry points: group creation → members land on the shared branch → single managed PR created and synced. *(R9)* + +**Dependencies:** U1–U7. + +**Files:** +- `packages/dashboard/src/__tests__/` — extend `planning.test.ts`, `mission-e2e.test.ts` / `mission-integration.test.ts`. +- `packages/engine/src/__tests__/reliability-interactions/shared-branch-group-lifecycle.test.ts` — full lifecycle assertion. + +**Approach:** Drive each entry point through to a single PR, asserting member enumeration (U1), unified gating (U2), safe routing (U3), real PR creation (U5), and sync/terminal (U6).

Planning → shared group → all subtasks land → one PR created, synced to N/N, merged → `prState=merged`. +- Covers F (mission E2E). Mission triage → shared group → members land → one PR; abandon mid-flight → `prState=closed`. +- Re-running promotion in either flow → no duplicate PR. +- A self-healing finalize during the flow keeps members on the group branch (no lost work). + +**Verification:** Both entry points reach a single managed PR with correct terminal state; no duplicate PRs; no mis-routed members. + +--- + +## Risks & Dependencies + +- **Data loss (high).** Shared members share branch lineage; a regression in merge-target resolution can strand work (2026-05-23 incident).

From 7c8a3d407599269ff46f50bb118bc715f9a178f0 Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Wed, 3 Jun 2026 09:04:36 -0700 Subject: [PATCH 07/46] feat(acp): per-category permission floor + HITL + cancel drain (U5) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The security floor for session/request_permission. Classifies each tool call's kind into a Fusion action category and reads the per-category disposition from the live policy (never a preset shortcut — S1/KTD3a), so a custom rule blocking command_execution is honored even under the default unrestricted preset. Selects allow_once only, never allow_always (S2). Unmappable/missing/other kind and missing gate/policy default-deny; require-approval routes through the gate's HITL closures (createApprovalRequest -> pauseForApproval -> re-read status) or default-denies when no approver exists. requestPermission tracks in-flight requests and drains them cancelled on teardown (KTD4a). Couples only to a local PermissionGate (no @fusion/engine import, KTD3). +29 tests (106 total).

Adds the Risk S1 default-policy safety: an acpAllowUnrestricted acknowledgement (default false) — without it, a blanket allow on a sensitive category is escalated to approval rather than auto-approved under the allow-all default policy, applied in both the permission floor and fs write gating. Adds docs/acp-contract.md (launch/readiness + failure taxonomy), a README with the AGENTS.md-required upstream evidence (SDK repo/docs/release/integrity), a bundle-output test for the staged plugin, and a @runfusion/fusion minor changeset.

The PR number/url/state are persisted on the branch group and promotion is idempotent — re-running never opens a second PR (an existing persisted or open PR is reused). The GitHub client is injected into the engine via the same option-callback seam as `processPullRequestMerge`, wired at the `fn daemon`, `fn dashboard`, and `fn serve` construction sites. PR creation only happens for eligible (completion-gated, auto-merge-allowed) groups, and a GitHub failure leaves the group recoverable rather than persisting a false PR state. The single managed group PR is now kept in sync through its terminal lifecycle: as additional members land, the PR body is rewritten with the latest member checklist and x/N completion (idempotent body rewrite — sync failures are non-fatal and retry on the next landing). When the persisted PR is closed or merged out-of-band on GitHub, the stored `prState` is reconciled rather than re-opened.
