- Frontend on nginx-unprivileged (non-root, container port 8080)
- Replace unmaintained passlib with bcrypt 5.0.0 (hash-compatible)
- Pass DOCS_ENABLED through to the backend container
- Raise db mem_limit to 768m for MySQL 8.4

 ### Known / accepted
 - npm audit: vite ≤6.4.2 and esbuild advisories affect only the **dev server**, which production never runs (it serves the static build). Fixing them fully needs Vite 6.4+/7.
 - mysql:8.4.11 has upstream findings in Oracle's image: curl, bundled Python tools, and gosu's Go stdlib.

+## v1.1.1 — 2026-09-25
+
+Low-severity items from the 2026-09-24 review.
+
+- Frontend runs as non-root: `nginxinc/nginx-unprivileged:1.30.5-alpine`, listening on **8080** in the container. Host port 8054 is unchanged, so NPM needs no change.
+- Replaced unmaintained `passlib` with `bcrypt` 5.0.0 directly. Existing `$2b$` hashes still verify; passwords are truncated to 72 bytes as before. A malformed hash now fails verification instead of raising.
+- `DOCS_ENABLED` is now passed to the backend container (default `false`), so the README instructions work.
+- db `mem_limit` 512m → 768m (MySQL 8.4 was at ~86% of 512m).

 ### Post-deploy regression
 
 After the HIGH deploy, `POST /api/sessions/{id}/timer` returned **500 on every call**: 8 failures, 0 successes, starting 06:43 UTC. FastAPI 0.141 raises on a failed lazy-load of `current_block.subject.options` during response serialization, where 0.115 silently skipped it. The first smoke test didn't cover timer actions. Fixed in v1.1.0 by eager-loading `Subject.options` in `sessions.py` and `dashboard.py`. The smoke test now covers the full timer lifecycle, the TV dashboard with an active block, schedule/subject writes, and every parameterless GET route (from the OpenAPI spec).
 
+### v1.1.0 deploy verification
+
+All 3 containers are healthy with 0 restarts, and log rotation is active (10m × 3). Public `/api/health` returns 200. Production timer actions return 200 (4 of 4 right after the deploy). Tagged `v1.1.0` and pushed. The pre-review rollback images (`rollback-20260924`) were pruned by the user; `rollback-20260924b` (the HIGH-fix build) remains.
