 - **Production-verified work:** None.
 - **Blocked work:** SEC-006 parser upgrades remain outside the scoped frontend advisory permission; PROD-001/003/004 and REL-001 require documented production access and unfinished dependencies. Real provider, SMTP/MariaDB and production environments are unavailable; DEP-001 awaits approved merge/live verification. The in-app browser is available for local UI checks.
 - **Deferred work:** None. Conditional multi-replica coordination, model deletion, realtime operation delivery and unrelated production changes remain outside current packages.
-- **Immediate order:** CV contact contrast; JOBS-002 parity/regression; cross-app contrast/accessibility; PRODUCT-001; VER-001. The admin version indicator is pushed in `a6cffe0`; Career lossless manual persistence is locally complete. External-only work remains skipped, not allowed to stall this queue.
+- **Immediate order:** JOBS-002 parity/regression; cross-app contrast/accessibility; PRODUCT-001; VER-001. Admin version (`a6cffe0`), Career lossless persistence (`f0b9b22`) and CV contact contrast are locally complete. External-only work remains skipped, not allowed to stall this queue.

-- **Test status:** backend 642/642; affected Career/import/profile/job paths 112/112; Career/Profile UI 17/17; prior frontend 53/53 suites and 221/221 tests plus optimized production build/TypeScript pass. The version indicator also has focused Auth/System 36/36 and AppShell 2/2 evidence. Prior AI sidecar 22/22, Playwright 6/6, pathological nine-page Chromium/PDF proof and npm audit 0 evidence remain current. Historical JT-019 and Jest force-exit/open-handle behavior remain recorded.

Real Chromium contrast/overflow checks pass and the harder pathological fixture exports a 17-page A4 PDF with final-page text.

 - **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:** Unchanged and unverified. No provider/model call, model pull, external request or paid API occurred.
 - **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.
