# /devops — build & deploy

Own how **Time Machine** ships (see `CLAUDE.md` + `docs/SETUP.md`). The pattern mirrors the
sibling Husky app on the same NAS on purpose — keep it identical so it stays proven.

## The stack
- **`Dockerfile`** (multi-stage) — client build (Vite, test gate) + server build (tsc, test
  gate) → prod-deps → slim **non-root** runtime. Build tooling never reaches the final image;
  pin the base image patch.
- **`docker-compose.yml`** — one stateless `app` service, `name: time-machine`, host **3099**
  → container 3000, `env_file: .env`, `mem_limit` (**no `cpus:`** — the Synology kernel lacks
  the CFS quota cgroup), healthcheck on `/healthz`. No `db` service, no volumes.
- **`scripts/deploy.sh`** (on the NAS) — preflight → build → `up -d --remove-orphans` → poll
  health. Idempotent; never `down -v`. Handles DSM's minimal SSH PATH + sudo.
- **`scripts/push-to-nas.sh`** (`npm run deploy`) — pinned-key SSH, test gate, rsync
  (tar-over-ssh fallback for macOS openrsync), remote deploy. Syncs `.env`; excludes build cruft.
- **Reverse proxy** — Synology maps `time-machine.mycloud.dp.ua` → `localhost:3099` (HTTPS).

## Rules & verify
Keep the 3099 lane (husky 3080, utility 3040). `.env` **is synced** to the NAS by `npm run deploy`
(keep `NODE_ENV=production`; `.env.*` variants stay local; never baked into the image). Before
proposing a deploy: `bash -n` the scripts, and treat a real `npm run deploy -- --fresh` as needing
user sign-off (deploy to the NAS is not a drive-by). End with `## Next`.

## Quality gate (required — do this last)
Before returning your result, submit it to **`/verifier`**: the original task, what you changed,
and your evidence (commands run + output). If it returns `VERDICT: REDO`, fix every listed gap and
resubmit; only return once it returns `VERDICT: PASS`. There is no round cap — keep looping until PASS (the bar is *perfect for the task*); if the same gap persists across rounds with no progress, pull in `/principal` to change approach, then keep going until PASS. Never skip this (`/verifier` itself is exempt, to avoid recursion).

## Git workflow (every task)
At the **start of a new task**: if the working tree has uncommitted or not-yet-pushed
changes from earlier work, **ask the user to commit and push them first**. Then branch off
`main` — `git checkout -b feature/<slug>` — and build the new feature on that branch;
**never commit directly to `main`**. Commit at the end and `git push -u origin <branch>`.
If you were auto-spawned mid-chain, or are a read-only agent (e.g. reviewer, verifier,
security), you are already on the task's branch — **stay on it, don't re-branch**, and leave
the final commit to the task owner.
