Priivacy-ai/spec-kitty v3.1.0a3 on GitHub

Doctrine artifact discovery in subdirectories — all 7 doctrine repositories now use rglob() instead of glob(), so artifacts in subdirectories of shipped/ are no longer silently skipped (#396).
Dashboard /api/features empty response — StatusEvent.from_dict() now accepts both feature_slug and mission_slug field names and normalizes the legacy in_review lane to for_review.
Stale patch() targets caught at lint time — new scripts/check_patch_targets.py validates every @patch() target string resolves, added as an [ENFORCED] CI lint step (#394).
Architectural layer coverage guards — meta-tests fail when a src/ package has no layer assignment or a defined layer matches no module (#395).
Sonar reliability bugs — resolved 7 findings: unreachable code (S1763), identical branches (S3923), premature async task GC (S7502), always-true condition (S2583), tautological assertion (S3981), CSS shorthand override (S4657), parameter shadowing (S1226).
Async task GC in event emitter — asyncio.ensure_future() results held in _pending_tasks set with done-callback cleanup, preventing premature garbage collection.
check-readiness CI gate unblocked — post-release version bump missed after tagging v3.1.0a2 (#408).

CI test parallelization — fast-tests and integration-tests split into doctrine + core phases running in parallel (#397).
--mission-run as canonical CLI flag — added as alias for --feature across all CLI commands. --feature remains accepted as legacy alias.
Node.js 20 → 22 in CI workflows (current LTS).
Mutation testing CI job disabled — too slow to run reliably.
Ruff max line length increased from 120 to 164.
Defunct tests/legacy references removed.

RTK search tooling toolguide — new shipped doctrine artifact documenting RTK interception patterns and correct search tooling for worktree sessions.
last_updated field on Toolguide model and schema.
Integration tests for nested artifact discovery — 281-line test suite covering all 8 doctrine repository types.
integration pytest marker registered in pyproject.toml.
