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.

Quarantines the flaky active-session pruning coverage without hiding the rest of merger cleanup tests.
- Move the active-session pruning scenario into its own focused test file.
- Keep the broader merger cleanup suite in the reliability project.
- Point the quarantine ledger and engine default exclude at only the isolated flaky test.

Restore Pi-upgraded workspaces to keep Fusion resources accessible and recover title generation when configured models go stale.
- Mark read-only Fusion/Pi provider settings views as project-trusted so extension loading keeps working after Pi upgrades.
- Retry task title summarization with automatic model resolution when the configured provider model is missing from the Pi registry.
- Cover provider settings trust behavior and stale summarizer fallback paths with regression tests.
- Document the read-only settings trust contract and add a patch changeset.

The idle-worktree sweep (cleanupOrphans) and cap-enforcement sweep only
guarded isWorktreeResumeReserved (CLI resume sessions), not in-process
active sessions. scanIdleWorktrees treats a worktree as active only while
a non-done task points at it, but the executor transiently moves tasks to
done or nulls the worktree field mid-run — so a checkout backing a live
executor/merger/step/workflow session could be removed before the work
finished. Add the activeSessionRegistry.isPathActive guard to both loops,
mirroring reapUnregisteredOrphans (FN-4811/FN-5065).

Move undocumented flaky engine tests into the formal quarantine path.
- add quarantine ledger entries for flaky engine test files observed under concurrent/full-suite load
- exclude the quarantined engine test files from vitest projects so they no longer run in gate and reliability pools
- remove the undocumented it.skip markers by quarantining at the file/config level instead

Update @earendil-works/pi-coding-agent and @earendil-works/pi-ai from
^0.78.0 to ^0.79.1 across cli, engine, and dashboard. This brings in
Claude Fable 5 (claude-fable-5) on the Anthropic and Amazon Bedrock
providers.
Fusion's model picker is registry-driven (/api/models -> pi ModelRegistry,
filtered by provider, not model id), so Fable surfaces automatically for
users with Anthropic or Claude CLI auth configured — no Fusion-side model
list change needed.
Verified: all core packages typecheck clean against 0.79.1; boot smoke
(fn --help, /api/health 200, clean shutdown) passes.

Guarantee AI merge clean-room worktrees are pruned on merge completion and swept by task state.
- prune pre-existing same-task AI merge temp worktrees before starting a new merge and audit cleanup outcomes
- add task-aware tempdir sweep rules with a short grace period for done or archived tasks and immediate cleanup for deleted tasks
- extend merger and self-healing coverage and document the updated stale worktree policy

Stop the self-healing DB corruption test from leaking into unrelated tmpdir state while quarantining the known flake.
- mock node:os tmpdir usage so the test runs inside a per-test sandbox and cleans it up after each case
- add the flaky self-healing DB corruption test to the engine default exclude list
- record the quarantine entry and failure context in scripts/lib/test-quarantine.json

Prevent rebuilt dashboard tabs from reusing stale cached assets after a deploy.
- revalidate service-worker asset requests against the network before falling back to cache and bump the cache version
- suppress repeated version-change reloads for the same remote build and cover the new behavior with dashboard tests
- update engine heartbeat test expectations for summarized task creation metadata and add the published package changeset

- spy on [1mpiLog.log[22m instead of [1mpiLog.warn[22m in the structured logger diagnostics test
- keep the existing [skills] and [executor] assertions while matching the current logging path
