 - **Deferred work:** None. Conditional multi-replica coordination, model deletion, realtime operation delivery and unrelated production changes remain outside current packages.
 - **Immediate order:** the eight-item immediate queue is complete locally: admin version (`a6cffe0`), Career persistence (`f0b9b22`), CV contrast (`3b86ea2`), JOBS-002 (`deed948`), accessibility (`a7c2549`), PRODUCT-001 (`a25c31b`), VER-001 and tracking reconciliation. SEC-009 is complete at `842e793`; PROD-001 read-only evidence and the PROD-003 plan-only harness are complete pending this documentation commit. No further independent implementation remains.
 - **Status counts:** 8 `VERIFIED LOCALLY`; 25 `IMPLEMENTED — NOT VERIFIED`; 0 `IN PROGRESS`; 1 `NOT STARTED`; 5 `BLOCKED`; 0 `DONE`; 0 `DEFERRED`.
-- **Test status:** backend 657/657; frontend 58/58 suites and 237/237 tests; AI sidecar 22/22; Ollama benchmark harness 4/4 plus safe dry-run; optimized production build/TypeScript; EF model parity and MariaDB migration-script generation; Docker Compose config; safe-failure deployment preflight; and Playwright 9/9. Five real-SQLite deletion tests cover lockout, isolation, quarantine failure and restored-backup replay. npm audit 0 evidence remains current because the lockfile did not change. Historical JT-019 and Jest force-exit/open-handle behavior remain recorded.

Jest force-exit/open-handle behavior remains recorded.
 - **Deployment status:** Gitea pull-request run 609 passed the complete CI job in 4m20s. Deploy was intentionally skipped because the workflow deploys only a `push` to `main`; live remains unchanged. No merge/deployment was performed directly, no production migrations were run and the AI operation worker remains disabled by default.
 - **Production status:** State unchanged. Sanitized read-only SSH inventory was performed; no logs, prompts, private rows/content or secret values were read, and no provider/model call, model pull, service restart, file/config change, backup, restore, migration or deployment occurred. It confirmed all-interface Ollama/frontend listeners and stale database-only backups as rollout blockers.
-- **Known regressions:** None found by automated/local browser checks. Jest still needs `--forceExit` and reports its existing open-handle notice. Email-provider/send tests are fake/local only; real delivery is not claimed. Current MAIL browser evidence is 1280×720 only because the browser surface could not resize or perform native Tab traversal. Interrupted attempts are aged after 15 minutes and notified without retry; the five-minute scan is unmeasured on a large ledger. Direct clean EF-only SQLite migration still hits the pre-existing historical blank-chain defect before later migrations; normal startup owns reconciliation. Cross-feature monthly AI usage accounting remains a rollout gap.

 - **Outstanding security findings:** JT-001 repository ownership remains High deployment risk until migration/inventory/provider checks; production portion of JT-002; JT-006 and SEC-009 production retention/restore plus JT-011/JT-012/JT-022 prerequisites. JT-005 foundations are implemented; AI worker activation awaits controlled rollout. Production still exposes ports contrary to the release-branch contract, and JT-007/JT-008/JT-010 lack provider/production verification.
