# Final release report

> **Historical snapshot (2026-07-19).** The current release state is maintained in

> 2026-07-19. Compiled at the release-candidate stage after the CI runner failure was investigated and

## Release status

### READY WITH DOCUMENTED RISKS

The code and deployment path have no known blocker. The most recent CI failure — which had been assumed
environmental — was found to be a **real code bug** and is fixed and verified on the runner's exact ICU
version. What remains are (a) the runner's separately-evidenced instability, which the owner must
confirm is gone by re-running CI, and (b) owner-only verification that cannot be automated (sign-in,
production data, production backup). None of these is a code defect.

## Verification summary

### Backend
- **Tests:** 420 passing, Release configuration, real build (not `--no-build`).
  - Windows (local).
  - Linux, full ICU — Debian 12 / libicu72 and Ubuntu 24.04 / libicu74.
  - Linux under `DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1`.
  - **Ubuntu 20.04 / libicu66 with .NET 9.0.316 installed via `dotnet-install.sh` — the exact CI
    runner environment — 420/420.** This is the environment that failed before the ICU fix.
- **Build:** backend Docker image builds.
- No test weakened, skipped, filtered, or disabled.

### Frontend
- **Tests:** 128 passing (36 suites).
- **TypeScript:** `tsc --noEmit` clean.
- **Build:** production build clean; frontend Docker image builds.

### Database
All four startup scenarios run against live MariaDB 11 and SQLite, with the real backend binary:

| Scenario | Result |
|---|---|
| Empty MariaDB | 42 tables created, healthy, 0 exceptions, 0 skipped indexes |
| Populated MariaDB restart | idempotent — 42 tables, rows preserved |
| Partially-migrated MariaDB | healed 35 → 42, 7 Phase 4/5 tables recreated, surviving rows preserved |
| Fresh SQLite + restart | schema built, idempotent, 0 errors |

Startup order confirmed in logs: **reconcile → `Database.Migrate()` → reconcile → seed**. All seven
Phase 4/5 migrations have empty `Up` bodies; the reconciler owns their DDL. No duplicate ownership.

### Deployment
- **Backup:** the real `deploy.sh backup_database` produces a valid gzip dump with 42 `CREATE TABLE`
  statements and the `Dump completed` trailer. Validation rejects empty/truncated/wrong-type files.
  Backup runs **before** build/replace (verified by line order).
- **Restore:** dump restored into a clean MariaDB 11 container; all 42 tables and every row count
  matched; the application started healthy against the restored database.
- **UTF-8 / Norwegian characters:** `Ærøskøbing`, `Søknad – Bjørn Håkonsen`, `bjørn@dåg.no`, and
  career-profile Norwegian text survived a full backup → restore **byte-exact** (HEX compared).
- **Health checks:** `/health` 200 (anonymous, no DB touch); frontend `wget`; compose gates frontend
  on backend `service_healthy`; 4 healthcheck blocks defined.

### Security
- **Authorization:** every user-owned controller has class-level `[Authorize]`; 5 user endpoints return
  401 unauthenticated; independent of the `Auth:Require` flag.
- **Tenant isolation:** 25 global query filters, all deny-on-null.
- **Public endpoints:** `/health` 200, `api/auth/config` 200, public CV unknown slug 404 (not 401/500,
  no leak). `ai-service` unreachable from outside its private network; authenticates its caller.

## Remaining risks

Separated by kind. Nothing here is hidden.

### Code issues
- **None open.** Fixed this release cycle: the ICU language-alias precedence bug (`fba858e`), the
  MariaDB follow-up-reminder index (`95646e1`), the nondeterministic timeline test (`c1ff98f`), the CV
  language ICU drop (`9681618`), `/health` version (`8f6f2ba`), and the deploy backup env-loading
  (`66b02bc`).

### Infrastructure issues
- **Runner instability (Findings A & B)** — separate from the ICU bug and still unconfirmed-fixed. The
  test host has died at ~3 s and the deploy SSH step at ~3 s on prior runs, with host-access-only
  diagnostics. **The ICU fix removes the known code cause of red, but does not prove the runner is
  stable.** The owner should re-run CI; if it still dies at a fixed ~3 s mark regardless of the change,
  Findings A/B are confirmed and need host access (`journalctl -u act_runner`, runner resources).
- **Runner ICU is old (libicu66 / Ubuntu 20.04-class).** Legitimate as a signal — it caught a real bug
  — but worth upgrading so the CI environment is closer to production and to developer machines.

### Manual owner verification (cannot be automated)
- **Sign-in and the authenticated journey** — requires a password; no tool here handles one. Use
  `docs/deployment/manual-smoke-test.md`.
- **Production backup on real data** — no production access from this environment; no credentials were
  discovered or guessed. Owner must run one real backup + scratch restore, including the æøå check.
  See `docs/deployment/backup-restore.md`.
- **Production dataset scale** — dump duration, disk headroom, and lock behaviour are unproven on a
  large real database.

## Deployment recommendation

**Deploy with documented risks**, in this order:

1. **Re-run CI** with the ICU fix included. If the `test` job now passes, the current known red is
   cleared. If it still dies at a fixed early mark, Findings A/B are confirmed environmental — decide
   whether to deploy manually from the verified commit or fix the runner first.
2. **Owner runs a production backup + scratch restore** (with the æøå check) before deploying.
3. **Deploy** via `deploy/deploy.sh` — backup is automatic and gates the deploy.
4. **Owner runs `docs/deployment/manual-smoke-test.md`** immediately after.

Do not treat a green pipeline as sufficient on its own: two real defects this cycle passed local test
runs and only surfaced against a real container or the runner's older ICU. The manual smoke test is
not optional.
