@@ -10,6 +10,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Auth: stateless JWT sessions (HS256, 30d, HttpOnly cookie unchanged) replace the `user_sessions` table (Alembic revision drops it; all sessions invalidated at deploy); slowapi run throttle replaces the hand-rolled sliding window; mail via jinja template + fastapi-mail (same copy/fallback contract); CLIs on typer; `JWT_SECRET` enforced by `check_prod.py`.
 - Forms: thin variant components over shared `components/kirche/_form_core.py` (codegen-inlined by `kirche_node()` for LFX; all 5 flows regenerated + level-4 validated), structured `visible_if` key alongside legacy markers, `LangflowClient.upsert_flow` + `scripts/push_flows_to_langflow.py` (6 canonical flows pushed to Langflow UI).
 - Store/sync: single `next_version_no` query per version, validation only at the `create_version` choke point, mtime-cached `.flowsignore`.
+- Fix batch: typer CLIs exit non-zero via `typer.Exit` (`check_prod` gate works again); JWT expiry 30d→7d with startup warning and new expiry/deleted-user tests; deleted dead `resolve_tenant`, test alias helpers now delegate to `conftest` (flows/approvals/sync/deploy suites migrated to shared fixtures); `AdminTab` reads via react-query; Mantine aligned to 9.6.3 (consistent lockfile, `npm ci` green).
 - Tests (full real LFX kept): shared `conftest` helpers + `tests/_harness.py` adopted by fixtures and smoke script, parametrized matrices (export stems, check_prod env, deploy failures, sync listing failures, API auth probes, input_schema types), relaxed brittle asserts (ui:order sets, per-flag cookie asserts, SSE any-match).
 - Frontend: react-query reads + notifications, `useForm`+zod static forms, shared `DecisionButtons`/`ErrorAlert`/`JsonView`/`FormattedDate`/`RunsTable`/`Landing` blocks, new aggregate `GET /api/runs` kills the Tasks N+1, `Promise.all` version fetches, `sharp` icons, selector-based screenshots, dead photo removed.
 ### Added
