Refresh repo docs to match what was built (Maestro 3b22e48b)

ARCHITECTURE.md: drop the Feature 01 "planned application" framing; add the missing packages (forwarded, secureurl, home, ai/aisettings) to the layout; add photo backfill (text as on dev), a job-kinds table and a Deployment section (compose stack, systemd units, release flow, automated deploy of main); correct the onboarding notifications step, which now subscribes to Web Push. AGENTS.md: the internal/* list is no longer "planned" and names every package; migrations/ and deploy/ describe what exists; cmd/vapidgen and the sqlc targets are listed; the release flow notes the auto-deploy of main. README.md: replace the scaffold status with the production URL, the stack, sqlc-check, and where the deploy runbook lives (deploy/RUNBOOK.md + CTXD).

+# MealQuest deploy runbook
+
+The one way to deploy MealQuest to production: the docker compose project
+`mealquest` on office-srvr `10.60.1.14` (see
+[ARCHITECTURE.md](../docs/ARCHITECTURE.md#topology)). Production runs `main`
+or a release tag; only `overseer` merges `dev` → `main`. Every deploy builds
+on the host, from the checked-out commit, with `make docker`.
+
+Host setup (clone, firewall, the systemd unit, Traefik, DNS, Litestream) and
+the database restore are in CTXD project `mealquest`, `RUNBOOKS.MD`. This
+file is the build, restart, verification and rollback procedure; where it
+uses a CTXD section, it names it.
+
+All commands run on `10.60.1.14` as `overseer`, in bash, from the checkout
+`/home/overseer/mealquest`. A block that ends with `FAILED` or a non-zero
+`$?` stops the deploy: do not go on to the next step.
+
+## How the image carries its version
+
+`make docker` runs `docker build --build-arg VERSION=<version>` and tags the
+image `mealquest:<version>`, where `<version>` is
+`git describe --tags --always` of the checkout (a release tag such as
+`v1.0.0`, otherwise the short SHA), with `-dirty` added when a tracked file
+is modified. The [Dockerfile](../Dockerfile) links it into the binary, and
+`/health` reports it:
+
+```json
+{"status":"ok","version":"v1.0.0"}
+```
+
+Never pass `--build-arg VERSION` by hand, and never build with
+`docker compose build` or `docker compose up --build`: compose passes no
+version, so that image reports `dev`.
+
+The compose service `mealquest` runs the image named `mealquest-mealquest`
+(compose's name for the image it would build; check with
+`docker compose -f deploy/compose.yaml config --images mealquest`). It
+already exists, so `docker compose up` uses it and never builds. A deploy
+points that name at the `make docker` image with `docker tag`. Every
+`mealquest:<version>` image is kept for rollback; do not prune them.
+
+## Prerequisites
+
+- `make`, `git`, `curl`, `python3` and Docker Engine with Compose on the
+  host (`make` is not in the base install: `sudo apt-get install make`).
+- `deploy/.env` (git-ignored, owner `overseer`, mode 0600) sets every
+  variable [`deploy/.env.example`](.env.example) sets, with
+  `MEALQUEST_BIND_ADDRESS=10.60.1.14`. It must not set the variables
+  `deploy/compose.yaml` fixes (`MEALQUEST_HTTP_ADDR`, `MEALQUEST_DATA_DIR`,
+  `MEALQUEST_SEARXNG_URL` and the `*_FILE` variables). Creating it: CTXD
+  `RUNBOOKS.MD` "Stack and first deploy" > "3. Environment file".
+- `deploy/secrets/` (git-ignored, mode 0700) holds `secret_key`,
+  `oidc_client_secret`, `google_client_secret`, `vapid_private_key` and
+  `litestream_key`, each owned by `10001:10001` with mode 0600, and
+  `searxng.env`, owned by `overseer` with mode 0600. Creating them: CTXD
+  `RUNBOOKS.MD` "Stack and first deploy" > "4. Secrets".
+- The compose file is the checkout's [`deploy/compose.yaml`](compose.yaml);
+  the systemd unit [`mealquest.service`](systemd/mealquest.service) starts
+  and stops it and is the only way the stack starts.
+- DNS and Traefik already route `https://mealquest.cubecraftlabs.com` to
+  `10.60.1.14:8090` (CTXD `RUNBOOKS.MD` "Reverse proxy (Traefik)", "DNS").
+
+Check `deploy/.env` and the secrets before every deploy (a new release may
+add a variable; the service refuses to boot without it). Both commands must
+print nothing:
+
+```sh
+cd /home/overseer/mealquest
+comm -23 <(grep -oE '^MEALQUEST_[A-Z_]+' deploy/.env.example | sort -u) \
+         <(grep -oE '^MEALQUEST_[A-Z_]+' deploy/.env | sort -u)   # variables missing from deploy/.env
+sudo find deploy/secrets -type f ! -perm 600                       # secrets not mode 0600
+```
+
+## Deploy
+
+### 1. Build
+
+Record the release production is running now, check out the new release
+and build its image. Nothing restarts.
+
+The rollback target is the version the running service reports on
+`/health`, read before the checkout changes, never the checkout's `HEAD`:
+after a failed or deferred deploy the checkout can be ahead of production.
+The block resolves that version to a commit and prints it as the rollback
+SHA. A running version of `dev` or `*-dirty` names no commit: the block
+fails, and the rollback target must be established by hand before going on.
+
+The checkout must be clean (the same test as the Makefile's `GIT_DIRTY`:
+no modified tracked file outside the generated `internal/frontend/dist`).
+The block computes the image tag exactly as `make docker` does, `-dirty`
+included, and checks that image exists after the build.
+
+```sh
+cd /home/overseer/mealquest && (
+set -euo pipefail
+fail() { echo "$*" >&2; exit 1; }
+built=
+trap 'st=$?
+if [ "$st" -eq 0 ] && [ -n "$built" ]; then echo "built: $built"
+else [ "$st" -ne 0 ] || st=1; echo "build FAILED (status $st)" >&2; fi
+exit "$st"' EXIT
+bind=$(grep -E '^MEALQUEST_BIND_ADDRESS=' deploy/.env | cut -d = -f 2-)
+[ -n "$bind" ] || fail "deploy/.env sets no MEALQUEST_BIND_ADDRESS"
+running=$(curl -fsS "http://$bind:8090/health" | python3 -c 'import json, sys; print(json.load(sys.stdin)["version"])') \
+  || fail "http://$bind:8090/health did not return a version: no running release to roll back to"
+case "$running" in
+  dev|*-dirty) fail "the running release reports $running, which names no commit" ;;
+esac
+git fetch --tags origin
+rollback=$(git rev-parse --verify --quiet "$running^{commit}") \
+  || fail "running version $running is not a commit in this repository"
+echo "rollback SHA: $rollback (running version $running)"   # RECORD it for rollback
+git checkout --detach "refs/remotes/origin/main^{commit}"   # or the release tag, e.g. v1.0.0

+make docker
+docker image inspect "mealquest:$v" > /dev/null 2>&1 || fail "no image mealquest:$v: the build failed"
+built="mealquest:$v"
+)
+```
+
+### 2. Ship and restart
+
+1. **Pre-restart gates.** Run CTXD `RUNBOOKS.MD` "Routine deploy and
+   rollback" > "Deploy" step 2 (a verified pre-deploy restore point; record
+   it with the rollback SHA) and step 3 (boot-required configuration). The
+   restart applies migrations the previous release refuses, so without that
+   restore point there is no rollback. If either fails, do not restart:
+   production stays on the previous release.
+2. **Point the stack at the new image and restart.** `docker compose pull`
+   fetches the pinned `litestream` and `searxng` images before anything
+   stops; `mealquest` is never pulled. The restart applies the firewall,
+   then runs `down` and `up -d`, and returns once `mealquest` passes its
+   healthcheck (`/health` inside the container).
+
+```sh
+cd /home/overseer/mealquest && (
+set -euo pipefail
+fail() { echo "$*" >&2; exit 1; }
+up=
+trap 'st=$?
+if [ "$st" -eq 0 ] && [ -n "$up" ]; then echo "restarted on: $up"
+else [ "$st" -ne 0 ] || st=1; echo "restart FAILED (status $st)" >&2; fi
+exit "$st"' EXIT
+v=$(git describe --tags --always)
+docker compose -f deploy/compose.yaml pull litestream searxng
+docker tag "mealquest:$v" mealquest-mealquest
+sudo systemctl restart mealquest
+for s in mealquest litestream searxng; do
+  id=$(docker compose -f deploy/compose.yaml ps --status running --quiet "$s")
+  [ -n "$id" ] || fail "$s is not running"
+done
+id=$(docker compose -f deploy/compose.yaml ps --quiet mealquest)
+health=$(docker inspect -f '{{.State.Health.Status}}' "$id")
+[ "$health" = healthy ] || fail "mealquest is $health, not healthy"
+up="mealquest:$v"
+)
+```
+
+On failure read `journalctl -u mealquest` and
+`docker compose -f deploy/compose.yaml logs mealquest`: a configuration
+error names the variable. Fix it or roll back.
+
+### 3. Verify the deployed version and a real screen
+
+A `/health` 200 alone proves only that some build is up. This step checks,
+on the LAN address and through Traefik, that:
+
+- `/health` reports exactly the checkout's `git describe --tags --always`;
+- `/` and the Plan screen's route `/plan` serve the built PWA shell (the
+  React root and a hashed `/assets/` script, not the placeholder page an
+  unbuilt embed serves);
+- that script is served as JavaScript.
+
+```sh
+cd /home/overseer/mealquest && (
+set -euo pipefail
+fail() { echo "$*" >&2; exit 1; }
+want=
+trap 'st=$?
+if [ "$st" -eq 0 ] && [ -n "$want" ]; then echo "deployed and verified: $want ($(git rev-parse HEAD))"
+else [ "$st" -ne 0 ] || st=1; echo "verification FAILED (status $st): the deploy is not verified" >&2; fi
+exit "$st"' EXIT
+v=$(git describe --tags --always)
+for base in http://10.60.1.14:8090 https://mealquest.cubecraftlabs.com; do
+  got=$(curl -fsS "$base/health" | python3 -c 'import json, sys; print(json.load(sys.stdin)["version"])') \
+    || fail "$base/health did not return a version"
+  [ "$got" = "$v" ] || fail "$base/health reports version $got, the checkout is $v"
+  for path in / /plan; do
+    page=$(curl -fsS "$base$path") || fail "$base$path did not return 200"
+    grep -q '<div id="root"></div>' <<< "$page" || fail "$base$path is not the PWA shell"
+    js=$(grep -oE 'src="/assets/[^"]+\.js"' <<< "$page" | head -n 1 | cut -d '"' -f 2) || true
+    [ -n "$js" ] || fail "$base$path references no built /assets/ script"
+    type=$(curl -fsS -o /dev/null -w '%{content_type}' "$base$js") || fail "$base$js did not return 200"
+    case "$type" in
+      text/javascript*) ;;
+      *) fail "$base$js is $type, not JavaScript" ;;
+    esac
+  done
+  echo "$base: version $got, PWA shell and $js served"
+done
+want=$v
+)
+```
+
+- `deployed and verified: <version> (<SHA>)` and `$?` = `0` → open
+  `https://mealquest.cubecraftlabs.com` in a browser: sign in and the Home
+  screen renders with the household's data. Then record the deployed
+  version and SHA, the rollback SHA, the pre-deploy restore point and the
+  date in the release's Maestro task.
+- `verification FAILED`, any error or a non-zero `$?` → the deploy is not
+  done. A version mismatch means the stack runs a different image than the
+  checkout: repeat step 2, or roll back.
+
+## Rollback to a previous release
+
+Rolling back points `mealquest-mealquest` at the previous release's
+`mealquest:<version>` image again; that release's checkout keeps the
+compose file and the version check consistent with it.
+
+1. **Check whether the rollback crosses a migration** with CTXD
+   `RUNBOOKS.MD` "Routine deploy and rollback" > "Rollback to a previous
+   SHA" (its first block), run against the rollback SHA that deploy step 1
+   recorded. If it prints versions unknown to the rollback SHA, restore the
+   database to the pre-deploy restore point first (CTXD `RUNBOOKS.MD`
+   "Restore the database", with `-timestamp <restore point>`); changes
+   since then are lost, so tell the household.
+2. **Check out the rollback SHA and retag its image.** An image built before
+   this runbook was not tagged `mealquest:<version>`; `make docker` builds
+   it from the same commit.
+
+```sh
+cd /home/overseer/mealquest && (
+set -euo pipefail
+fail() { echo "$*" >&2; exit 1; }
+P=<rollback SHA>   # recorded by step 1, from the running release's /health
+back=
+trap 'st=$?
+if [ "$st" -eq 0 ] && [ -n "$back" ]; then echo "rolled back to: $back"
+else [ "$st" -ne 0 ] || st=1; echo "rollback FAILED (status $st)" >&2; fi
+exit "$st"' EXIT
+git checkout --detach "$P"
+v=$(git describe --tags --always)
+docker image inspect "mealquest:$v" > /dev/null 2>&1 || make docker
+docker image inspect "mealquest:$v" > /dev/null 2>&1 || fail "no image mealquest:$v"
+docker tag "mealquest:$v" mealquest-mealquest
+sudo systemctl restart mealquest
+back="mealquest:$v"
+)
+```
+
+3. **Run step 3 above** unchanged. The rollback is done only when it prints
+   `deployed and verified:` with the previous release's version.
+
+## Automated deploys
+
+[`auto-deploy.sh`](auto-deploy.sh), installed as
+`/usr/local/sbin/mealquest-auto-deploy`, runs this runbook's deploy unattended:
+step 1 (build), the prerequisite `deploy/.env` and secrets check, CTXD
+`RUNBOOKS.MD` "Deploy" steps 2 (pre-deploy restore point) and 3
+(boot-required configuration), step 2 (ship and restart) and step 3
+(verify). No check is skipped or weakened, and it stops at the first
+failure. Every failure before the restart leaves production on the previous
+release.
+
+### What runs, and when
+
+[`mealquest-auto-deploy.timer`](systemd/mealquest-auto-deploy.timer) starts
+[`mealquest-auto-deploy.service`](systemd/mealquest-auto-deploy.service)
+at every quarter hour (`OnCalendar=*-*-* *:0/15:00`), plus up to 5 minutes'
+random delay; a check missed while the host was down runs as soon as it is
+back (`Persistent=true`). The service runs the script as `overseer` from the
+checkout, and only while `mealquest.service` is active: a stack stopped on
+purpose (a database or media restore) is skipped, not redeployed. Output goes
+to the journal (`journalctl -u mealquest-auto-deploy`).
+
+Each run fetches `origin` and compares `origin/main` with the last
+`deployed=` SHA in the deploy record `/home/overseer/mealquest-auto-deploy.log`:
+
+| `origin/main` | Result |
+| --- | --- |
+| is the last deployed SHA | No-op: exit 0, no output. |
+| CI (Gitea commit status) `pending` | Exit 0, no output; the next run checks again. |
+| CI `failure`, `error`, `warning`, or no status yet | Error in the journal, exit 1, nothing deployed. |
+| the last record line is `FAILED` for this SHA | Error in the journal, exit 1, nothing deployed: a failed deploy is never retried by the timer. |
+| CI `success` | Deploy. |
+
+The CI status is read from
+`https://code.cubecraftlabs.com/api/v1/repos/Maniacs_Mansion/MealQuest/commits/<SHA>/status`
+(public; no credential). A commit merged moments before a run can briefly
+report no status, which fails that run; the next run reads it again.
+
+A deploy appends one line to the record:
+
+```text
+2026-10-12T15:04:05Z previous=<rollback SHA> deployed=<SHA> restore_point=2026-10-12T15:01:59Z
+```
+
+`previous` is the rollback SHA (from the running release's `/health`,
+never the checkout) and `restore_point` the verified pre-deploy restore
+point: record both in the release's Maestro task. A failed deploy appends
+`<date> FAILED target=<SHA> status=<exit status>` and logs
+`auto-deploy FAILED (status <n>)` to the journal, adding whether it failed
+before the restart (production untouched) or after it (read
+`journalctl -u mealquest`, then fix or roll back). Either way the checkout is
+left at the target commit; the running release on `/health` stays the
+rollback target.
+
+### Install on the host
+
+The script and units are installed copies: repeat this whenever a release
+changes `deploy/auto-deploy.sh` or the units. From the checkout, at a release
+that contains them:
+
+```sh
+cd /home/overseer/mealquest
+sudo install -m 0755 deploy/auto-deploy.sh /usr/local/sbin/mealquest-auto-deploy
+sudo install -m 0644 deploy/systemd/mealquest-auto-deploy.service \
+  deploy/systemd/mealquest-auto-deploy.timer /etc/systemd/system/
+sudo systemctl daemon-reload
+```
+
+The timer refuses to deploy until the record holds a deploy, so seed it with
+one manual deploy of the release production should run (below), then start
+the timer:
+
+```sh
+sudo /usr/local/sbin/mealquest-auto-deploy --ref refs/remotes/origin/main
+sudo systemctl enable --now mealquest-auto-deploy.timer
+systemctl list-timers mealquest-auto-deploy.timer
+```
+
+To stop automated deploys: `sudo systemctl disable --now mealquest-auto-deploy.timer`.
+
+### Manual override
+
+```sh
+sudo /usr/local/sbin/mealquest-auto-deploy --ref <ref>
+```
+
+deploys an explicit ref (a SHA, tag or `origin/<branch>`) through the same
+blocks, bypassing the CI and no-op gates: for a roll-forward fix, a re-run
+after a `FAILED` record, or seeding the record. Run as root, the script
+re-executes itself as `overseer`; it holds a lock, so it never runs alongside
+the timer's run. It prints `deployed and verified:` and exits 0 only when
+step 3 passed.
+
+### Rollback
+
+Rollback is not automated: follow "Rollback to a previous release" above
+and CTXD `RUNBOOKS.MD` "Routine deploy and rollback" > "Rollback to a
+previous SHA", using the `previous` SHA and `restore_point` from the record.
+The timer does not undo a manual rollback: `origin/main` is still the last
+recorded deploy, so its runs are no-ops until `main` moves, and a new `main`
+then deploys as usual. Disable the timer if the rollback must hold.

+## Deployment
+
+Production is the compose project `mealquest` on 10.60.1.14
+([`deploy/compose.yaml`](../deploy/compose.yaml)): the `mealquest` image built
+from the root `Dockerfile`, `litestream` replicating the database to the
+NAS over SFTP, and `searxng` on the internal network only. Configuration is
+`deploy/.env` and file secrets in `deploy/secrets/`, neither committed. The
+services never restart themselves; systemd units in `deploy/systemd/` own
+the host:
+
+| Unit | Does |
+| --- | --- |
+| `mealquest-firewall.service` | Restricts port 8090 to Traefik in `DOCKER-USER`; required before the stack starts. |
+| `mealquest.service` | Starts and stops the compose stack. |
+| `mealquest-media-backup.timer` / `.service` | Backs up cached photos to the NAS nightly at 03:30. |
+| `mealquest-auto-deploy.timer` / `.service` | Automated deploy of `main` (below). |
+
+Releases: only `overseer` merges `dev` into `main`. The image carries its
+version (`git describe`: a release tag, else the short SHA), which
+`/health` reports. A deploy follows
+[`deploy/RUNBOOK.md`](../deploy/RUNBOOK.md) — build, pre-deploy restore
+point, boot-config check, ship and restart, verify the deployed SHA and a
+real screen — with rollback to the previous release. The automated deploy
+([`deploy/auto-deploy.sh`](../deploy/auto-deploy.sh), installed as
+`/usr/local/sbin/mealquest-auto-deploy`) runs those same steps unattended:
+its timer checks every quarter hour (plus up to 5 minutes' random delay),
+and deploys `refs/remotes/origin/main` only when it differs from the last
+SHA in the deploy record `/home/overseer/mealquest-auto-deploy.log`, its
+Gitea CI status is `success`, its last attempt did not fail, and
+`mealquest.service` is active. It stops at the first failure and never
+retries a failed SHA; `--ref <ref>` is the manual override. Installing,
+seeding the record and enabling the timer are host steps in the runbook's
+"Automated deploys". Database restore and the boot configuration are in
+CTXD `RUNBOOKS.MD`.
