Add an optional systemPromptOverride to spawnAgentParams. When non-empty,
the spawned child runs under that persona system prompt instead of the
generic child base prompt (executor instructions still appended), so a
caller can spawn a specific persona — the primitive the compound-
engineering reviewer/research fan-out needs.
Two spikes confirmed the need: fn_spawn_agent had no persona param, and
Fusion has no plugin agent-contribution channel — so the lightweight path
is a generic override here + plugin-local persona defs the skill reads and
passes inline (revised KTD-4/U2/U3 in the plan). Behavioral coverage lands
with U10.

U1: workflow-step sessions now carry FUSION_WORKFLOW_STEP=1 (scoped to
the step session, not the main executor) so skills detect autonomous
context and surface questions via await-input instead of a dead blocking
tool.
U8: bundle ce-commit, ce-commit-push-pr, and ce-resolve-pr-feedback
(vendored from compound-engineering 3.9.4) so the CE merge/PR flow has
its skills. Registered in COMPOUND_ENGINEERING_SKILLS; manifest test
updated.

Reconcile the FN-352 no-commit coordination guard skip with main's
independently-landed FN-424 work. Both branches added a no_commits
guard bypass at the same fn_task_done call site:
- FN-352 (this branch): getNoCommitEligibilityReason(task) covering
Review Level 1 coordination prompts with board-only scope and
explicit no-source intent (e.g. "Do not change product source").
- FN-424 (main): evaluatePromptDerivedNoCommitEligibility(...) plus
non-blocking audit logging of the skip.
Their prompt phrase-matching differs, so neither alone satisfies the
merged test file. Resolved by OR-ing both eligibility checks and
wrapping the skip in main's audit-logging block. Both helpers still
refuse the contradictory implementation+coordination prompt.
All 18 executor-task-done-invariant tests pass; engine typecheck clean.

Self-healing now resumes stranded assigned in-progress work when an agent has no active run or execution.
- Add a self-healing pass that groups stale assigned in-progress tasks by durable agent and calls the executor resume seam without moving tasks backward.
- Emit run-audit telemetry for reattached orphaned executions and wire the resume hook through the in-process runtime.
- Cover grace windows, pause/active-run/active-execution guards, task filtering, and registration order with engine tests.
- Document the recovery behavior and add a patch changeset for the published CLI package.

Resolve conflicts from main's FN-6232 single-source triage prompt refactor:
- Drop the inline FAST_TRIAGE_SYSTEM_PROMPT const removed by main; the fast
triage prompt now lives in agent-prompts.ts (planning-fast seam).
- Migrate the PR's no-commit/operational-routing heuristic edits into the
fast block of agent-prompts.ts (standard block already carried them).
- Point triage tests at FAST_PLANNING_PROMPT/TRIAGE_POLICY_PROMPT instead of
the removed const.

Quarantine unrelated engine test flakes so the gate avoids known unstable fixtures.
- Add the soft-delete blocker residue reliability test to the quarantine ledger and reliability interaction exclusions.
- Add the bubblewrap sandbox backend test to the quarantine ledger and engine-core exclusions.

Move frontend UX criteria out of triage self-instructions and into deterministic workflow policy.
- Add a shared frontend UX policy helper that matches frontend file scopes and injects the byte-equivalent checklist idempotently.
- Apply the policy during triage finalization and persist the updated PROMPT.md when applicable.
- Replace the legacy prompt-based injection instructions with a pointer to the deterministic policy.
- Cover path matching, insertion behavior, and checklist parity with focused core tests.
- Add a minor changeset for the published Fusion package.

Stabilize the self-healing dirty worktree recovery test by avoiding timer and async cleanup races.
- Force real timers for branch conflict reclaim tests.
- Provide explicit integration branch settings and dispatcher behavior for the recovery path.
- Use synchronous fixture setup and cleanup around the recovery patch assertion.

Ensure assigned agents resume task work even when their heartbeat loop is idle.
- add deferred assignment refiring when an agent is assigned work without an active heartbeat run
- track in-process runtime activity so scheduled work is not double-started
- cover idle, active, and concurrent heartbeat assignment paths with scheduler and runtime tests
- document the deferred assignment wake-up behavior and add a changeset

Deduplicate self-healing log entries for queued tasks that remain blocked by the same active file-scope overlap.
- Track the last active overlap blocker logged per task and skip duplicate preserved-queued log entries across self-healing passes.
- Clear the memo when blockers change, resolve, or the manager stops so legitimate future recoveries are still logged.
- Cover unchanged blockers, blocker changes, resolved blockers, stop/reset behavior, and FN-5488 stale-blockedBy preservation with regression tests.

Keep task detail PR and review affordances synchronized with the current project auto-merge setting.
- Thread the live auto-merge value into task detail modals and list split-pane detail views.
- Prefer the live auto-merge setting over the stale fetched modal snapshot while preserving task-level overrides.
- Cover PR and review tab behavior for auto-merge on/off and document the dashboard behavior.
- Evict flaky engine gate entries and add a patch changeset for the published CLI package.

Rescue the already-merged self-healing real-git test while quarantining a separate flaky merger AI suite.
- Call the already-merged recovery path directly in the rescued test and assert specific audit event types instead of exact total counts.
- Remove self-healing-already-merged.real-git.test.ts from the engine default quarantine list and ledger.
- Add merger-ai.test.ts to the engine default quarantine list and quarantine ledger with FN-6238 evidence.
