   budgets by client and slug, and removed/ignored the tracked expired acceptance JWT artifact.
+- Replaced the admin user list's per-user role lookup with a fixed two-query relational projection,

+- The current Job email UI uses an additive `/api/correspondence/page` contract with bounded page

 ## Validation limitation
 
 The first focused Jest invocation exhibited the repository's open-handle delay. The passing focused and full runs used `--forceExit`; the full run took 228.709 seconds. A Next build process also failed to exit after compilation; only the exact PIDs started by those build attempts were stopped, then a clean build completed. This is recorded as tooling/runtime behavior, not hidden.

 - **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. The direct clean EF-only SQLite defect and synchronous AI accounting gap are closed; migration/reconciler dual ownership remains architectural debt.
