Rescues the database recovery corruption test by reducing its fixture size and removing its quarantine.
- Reduce recovery test fixture rows so sqlite3 .recover is not overfed while still corrupting a B-tree page.
- Re-enable packages/core/src/__tests__/db.test.ts in the core Vitest config.
- Remove the db recovery test entry from the quarantine ledger.

Classify the archive FTS churn and merge-queue hook timeouts as deterministic test-cost fixes instead of quarantines.
- Reduce the archive FTS churn fixture while preserving rebuild shrinkage and search coverage.
- Use in-memory TaskStore setup for merge-queue cases that do not require disk persistence.
- Keep disk-backed coverage for legacy migration and competing-store lease arbitration.
- Verification: targeted archive FTS + merge-queue run passed in 7.47s versus 27.69s before the fix.

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.

Quarantine the flaky deferred-hook title summarization coverage while preserving focused store-create coverage.
- Extract the deferred task-created hook summarization test into its own file.
- Exclude the extracted test file from the core Vitest suite.
- Record the flake investigation and quarantine rationale in the test quarantine ledger.

Stabilize the checkout leasing AgentStore regression test setup.
- Recreate the nested checkout-leasing AgentStore with an in-memory database after replacing the TaskStore.
- Keep the disk-backed TaskStore for persistence assertions while avoiding a shared disk-backed AgentStore database lifecycle.
- Let the top-level cleanup own AgentStore closure to avoid double-closing in the nested hook.

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.

Close plugin-store migration test database handles so migration cleanup does not hang.
- Close legacy project database handles after seeding plugin rows.
- Close central and local database handles after idempotency assertions.
- Preserve the migration coverage while preventing open handles from delaying test teardown.

Stabilize the process supervisor cascade teardown assertion without relying on the lifetime timer.
- Disable maxLifetimeMs for the explicit cascade teardown test so it cannot race the test's wait window.
- Assert the supervised child exits from SIGTERM and the supervisor registry is cleaned up.
- Keep the grandchild termination assertion explicit after cascade cleanup.

Title summarization now accepts oversized task descriptions while bounding the model prompt.
- Remove the 2000-character validation ceiling for summarize-title requests.
- Truncate long descriptions only at model-input time with a dedicated exported cap.
- Update route/API docs and tests for long-description behavior.
- Add a patch changeset for the published Fusion package.

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.

Use per-invocation Vitest worker roots to keep compound-engineering tests from timing out on stale temp fixtures.
- Allocate a fresh FUSION_TEST_WORKER_ROOT during Vitest global setup and remove it during teardown.
- Preserve per-worker fallback root creation when global setup is not available.
- Clean compound-engineering harness project roots on close and cover the setup invariants with regression tests.

FN-6035 modeled the merge lifecycle as a branching subgraph of merge/
retry/branch-group primitives instead of a single `merge` seam, but the
linear workflow compiler still tried to lower those nodes and rejected
merge-gate's fan-out — so task creation failed with "node 'merge-gate'
branches into 2 edges — graphs with branches require the workflow
interpreter (deferred)".
Treat the merge-region primitive kinds (merge-gate, merge-attempt,
manual-merge-hold, retry-backoff, recovery-router,
branch-group-member-integration, branch-group-promotion, pr-merge) as an
engine-owned terminal boundary: exempt from the single-edge linearity
rule and never lowered to a step. Linear-prefix workflows compile to
their pre-merge step list again.
Also refresh the stale builtin-workflows assertions that referenced the
removed `merge` seam node.

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.
