+
+## Stack and first deploy
+
+The compose stack is `deploy/compose.yaml`: the `mealquest` service (built
+from the repository `Dockerfile`, runs as uid/gid 10001, listens on 8080 in
+the container), the `litestream` service and the `searxng` recipe-search
+sidecar (see "Recipe search (SearXNG)"). Data lives in the named volume
+`mealquest-data`.
+
+### 1. Choose and check the port
+
+The container's 8080 is published on `10.60.1.14:8090`. Ports 8080 and 8081
+on this host belong to NestQuest, so 8090 was chosen. Before the first
+deploy it was checked free with:
+
+```sh
+ss -ltnp | grep 8090   # printed nothing
+```
+
+After the deploy the same host shows NestQuest on 8080/8081 and MealQuest
+on 8090:
+
+```
+LISTEN 0 4096 10.60.1.14:8080 0.0.0.0:*
+LISTEN 0 4096 10.60.1.14:8081 0.0.0.0:*
+LISTEN 0 4096 10.60.1.14:8090 0.0.0.0:*
+```
+
+The published host port is fixed in `deploy/compose.yaml`, in
+`deploy/systemd/mealquest-firewall.sh` and in the Traefik route; change all
+three together.
+
+### 2. Clone
+
+The checkout lives at `/home/overseer/mealquest`, next to NestQuest's
+`~/nestquest` (not `/opt/mealquest`). Clone over HTTPS with a Gitea token,
+then reset the remote to the clean URL so the token is not stored in
+`.git/config`:
+
+```sh
+cd /home/overseer
+git clone https://<user>:<token>@code.cubecraftlabs.com/Maniacs_Mansion/MealQuest.git mealquest
+cd mealquest
+git remote set-url origin https://code.cubecraftlabs.com/Maniacs_Mansion/MealQuest.git
+git remote -v   # must show no token
+git checkout main
+```
+
+### 3. Environment file
+
+`deploy/.env` (git-ignored) is copied from `deploy/.env.example` and is
+mode 0600, owned by `overseer`:
+
+```sh
+cp deploy/.env.example deploy/.env
+chmod 600 deploy/.env
+```
+
+Then edit `deploy/.env` to the values below. In particular
+**`MEALQUEST_BIND_ADDRESS` must be changed**: `.env.example` ships
+`127.0.0.1` (a dev machine), and left as is the service listens only on
+the host's loopback, which Traefik cannot reach. Set it to the LAN address
+and check:
+
+```sh
+sed -i 's/^MEALQUEST_BIND_ADDRESS=.*/MEALQUEST_BIND_ADDRESS=10.60.1.14/' deploy/.env
+grep '^MEALQUEST_BIND_ADDRESS=' deploy/.env      # MEALQUEST_BIND_ADDRESS=10.60.1.14
+docker compose -f deploy/compose.yaml config | grep -A4 'ports:'
+#   host_ip: 10.60.1.14, target: 8080, published: "8090"
+```
+
+After step 5 the listener is `10.60.1.14:8090` (container port 8080):
+
+```sh
+docker compose -f deploy/compose.yaml port mealquest 8080   # 10.60.1.14:8090
+sudo ss -ltnp 'sport = :8090'                               # 10.60.1.14:8090 only, no 0.0.0.0 or 127.0.0.1
+```
+
+Values in use:
+
+| Variable | Value |
+| --- | --- |
+| `MEALQUEST_BIND_ADDRESS` | `10.60.1.14` |
+| `MEALQUEST_PUBLIC_URL` | `https://mealquest.cubecraftlabs.com` |
+| `MEALQUEST_SHUTDOWN_TIMEOUT` | `10s` |
+| `MEALQUEST_TRUSTED_PROXY` | `10.60.1.33` |
+| `MEALQUEST_DEFAULT_TZ` | `America/New_York` |
+| `MEALQUEST_OIDC_ISSUER` | `https://auth.cubecraftlabs.com/application/o/mealquest/` |
+| `MEALQUEST_OIDC_CLIENT_ID` | `i6zraqmWsF552b8nmte070LXz0SI5pRdArBxFxeq` (not a secret) |
+| `MEALQUEST_OIDC_ALLOWED_GROUPS` | `mealquest-admin` |
+| `MEALQUEST_SESSION_IDLE` / `MEALQUEST_SESSION_MAX` | `720h` / `4320h` |
+
+`MEALQUEST_HTTP_ADDR`, `MEALQUEST_DATA_DIR` and the `*_FILE` variables are
+set by `deploy/compose.yaml` and must not appear in `deploy/.env`.
+
+### 4. Secrets
+
+`deploy/secrets/` (git-ignored) is mode 0700, owned by `overseer`. Each
+file holds one value, is owned by `10001:10001` (host user `mealquest`) and
+is mode 0600. Compose bind-mounts file secrets with their host owner and
+mode, so any other owner or mode stops the container reading them and the
+service refuses to start.
+
+| File | Content | Mounted at |
+| --- | --- | --- |
+| `secret_key` | base64 of 32 random bytes; encrypts stored secrets (AES-256-GCM) | `/run/secrets/secret_key` |
+| `oidc_client_secret` | Client Secret of the Authentik provider `mealquest` | `/run/secrets/oidc_client_secret` |
+| `litestream_key` | dedicated SSH private key for the NAS (see "Backups") | `/etc/litestream/sftp_key` |
+| `searxng.env` | `SEARXNG_SECRET=<64 hex characters>`; SearXNG's secret key | not mounted; compose passes it as an environment variable |
+
+`searxng.env` is the one exception to the owner rule: compose itself reads
+it (as `env_file`), so it is owned by `overseer`, mode 0600.
+
+```sh
+mkdir -p deploy/secrets && chmod 700 deploy/secrets
+head -c 32 /dev/urandom | base64 > deploy/secrets/secret_key
+printf '%s\n' '<Authentik client secret>' > deploy/secrets/oidc_client_secret
+# litestream_key: see "Backups" > "Database — Litestream"
+sudo chown 10001:10001 deploy/secrets/secret_key deploy/secrets/oidc_client_secret deploy/secrets/litestream_key
+sudo chmod 600 deploy/secrets/*
+(umask 077; printf 'SEARXNG_SECRET=%s\n' "$(openssl rand -hex 32)" > deploy/secrets/searxng.env)
+sudo ls -la deploy/secrets   # three files mealquest mealquest, searxng.env overseer overseer; all -rw-------
+```
+
+The `mealquest` host user (uid/gid 10001) is created in "Media — nightly
+rsync"; until it exists `ls` shows the numeric ids.
+
+### 5. Firewall, then the stack
+
+Install the firewall unit and the stack unit first (see "Host firewall"
+and "Stack unit"), so port 8090 is never open to the LAN. Create the media
+directory (see "Media — nightly rsync"), then build and start:
+
+```sh
+docker compose -f deploy/compose.yaml build
+sudo systemctl enable --now mealquest   # starts mealquest-firewall first
+docker compose -f deploy/compose.yaml ps   # mealquest healthy, litestream up, searxng healthy
+curl -fsS http://10.60.1.14:8090/health
+curl -s -o /dev/null -w "%{http_code}\n" https://mealquest.cubecraftlabs.com/health   # 200
+```
+
+### Host checkout state on 2026-10-05
+
+The first deploy ran before Feature 07 reached `main`. The checkout is at
+`main` `9cddbbb` and the Feature 07 files under `deploy/` were copied in
+from the feature branch: `deploy/compose.yaml` and `deploy/.env.example`
+are listed in `.git/info/exclude`, the rest show as untracked. Before the
+first routine deploy of a `main` that contains `deploy/`, remove those
+`.git/info/exclude` lines and the copied files (keep `deploy/.env` and
+`deploy/secrets/`), or `git checkout` refuses to overwrite them:
+
+```sh
+cd /home/overseer/mealquest
+git status --porcelain --untracked-files=all deploy   # the copied files
+sed -i '/^deploy\/\(compose.yaml\|.env.example\)$/d' .git/info/exclude
+git clean -n deploy      # dry run: must not list .env or secrets/ (both git-ignored)
+git clean -f deploy
+```
+
+On 2026-10-06 `deploy/compose.yaml` was replaced and
+`deploy/compose.dev.yaml` and `deploy/searxng/settings.yml` were copied in
+from the Feature 10 branch (task 641f468b) to start the SearXNG sidecar;
+they too must go before that checkout (`git clean -n -d deploy` lists
+them).
+
+Then follow "Routine deploy"; the checkout brings the tracked copies back.
+
+## Authentik
+
+Sign-in is OpenID Connect against Authentik at
+<https://auth.cubecraftlabs.com>.
+
+| Object | Setting |
+| --- | --- |
+| Provider | OAuth2/OpenID provider `mealquest`, client type **Confidential** |
+| Redirect URI | `https://mealquest.cubecraftlabs.com/auth/callback` (strict) |
+| Signing | RS256, with the instance's signing key |
+| Scopes | MealQuest requests `openid profile email groups offline_access`; the provider's scope mappings include openid, profile, email and offline_access, and the `groups` claim is delivered by a property mapping (the default profile mapping carries `groups`) |
+| Application | name MealQuest, slug `mealquest`, provider `mealquest` |
+| Group | `mealquest-admin`, bound to the application; household members are added to it |
+| Client ID | `i6zraqmWsF552b8nmte070LXz0SI5pRdArBxFxeq` (not a secret; in `deploy/.env` as `MEALQUEST_OIDC_CLIENT_ID`) |
+| Client Secret | in `deploy/secrets/oidc_client_secret` only |
+
+MealQuest refuses a sign-in unless the user's `groups` claim (from the ID
+token, or from userinfo when the token has none) contains a group in
+`MEALQUEST_OIDC_ALLOWED_GROUPS`.
+
+Check discovery from the Docker host — the service discovers the issuer
+at boot and will not start if it cannot:
+
+```sh
+curl -s -o /dev/null -w "%{http_code}\n" \
+  https://auth.cubecraftlabs.com/application/o/mealquest/.well-known/openid-configuration   # 200
+```
+
+On 2026-10-05 discovery returned 200 with issuer
+`https://auth.cubecraftlabs.com/application/o/mealquest/` and
+`id_token_signing_alg_values_supported: ["RS256"]`.

+shared Traefik instance on 10.60.1.33 (Feature 07, task 0c1dc172). The
+route is a dynamic-configuration file that lives on the Traefik host only,
+at `/home/overseer/Code/traefik/config/dynamic/mealquest-ccl.yml`. Its exact
+contents:
+
+```yaml

+
+Traefik watches the dynamic directory, so saving the file loads the route;
+the certificate comes from `certResolver: myresolver` (Let's Encrypt,
+DNS-01 through Cloudflare). Check from the LAN:
+
+```sh
+curl -s -o /dev/null -w "%{http_code}\n" https://mealquest.cubecraftlabs.com/health   # 200
+```
+
+## DNS
+
+| Where | Record |
+| --- | --- |
+| Cloudflare, zone `cubecraftlabs.com` | `CNAME mealquest.cubecraftlabs.com` → `cubecraftlabs.com`, **proxied = true** (orange cloud). Because it is proxied, public resolvers answer with Cloudflare's anycast addresses, A and AAAA (AAAA on 2026-10-05: `2606:4700:3032::6815:34ed`, `2606:4700:3035::ac43:cd75`), never the origin |
+| Pi-hole primary 10.60.1.101 (`dns.ccl`), Local DNS records | `A mealquest.cubecraftlabs.com` → `10.60.1.33` (Traefik) |
+| Pi-hole secondary 10.60.1.85 (`dns2.ccl`), Local DNS records | `A mealquest.cubecraftlabs.com` → `10.60.1.33` (Traefik) |
+
+The local record must be on **both** Pi-holes, or clients using the
+secondary go out through Cloudflare. Check:
+
+```sh
+for s in 10.60.1.101 10.60.1.85; do dig +short @$s mealquest.cubecraftlabs.com A; done
+# 10.60.1.33 from each
+```
+
+**AAAA caveat.** The Pi-hole local record is A only, so both Pi-holes still
+forward AAAA queries and return Cloudflare's IPv6 addresses
+(`2606:4700:3032::6815:34ed`, `2606:4700:3035::ac43:cd75` on 2026-10-05). An
+IPv6-capable LAN client may prefer those and reach MealQuest through
+Cloudflare instead of directly through Traefik. It still works (Cloudflare
+proxies to the public route), but it is not the LAN path. If that matters,
+add a local AAAA override or block AAAA for this name on both Pi-holes.
+
+## Host firewall
+
+Docker publishes `10.60.1.14:8090` past the host's INPUT rules, so the
+port is restricted in the `DOCKER-USER` chain instead: only Traefik
+(10.60.1.33) and the host itself (10.60.1.14) may connect; every other
+source is dropped.
+
+Docker DNATs the published port to the container address and port 8080
+**before** `DOCKER-USER`, so a plain `-p tcp --dport 8090` rule never
+matches. The rules match the original destination `10.60.1.14:8090` with
+conntrack (`--ctorigdst 10.60.1.14 --ctorigdstport 8090 --ctdir ORIGINAL`)
+and are tagged with the comment `mealquest-firewall`. The port is never
+open while the rules change: if the chain does not already start with
+exactly the three rules, the script first inserts the DROP at position 1,
+then deletes its other tagged rules and inserts the two RETURN rules above
+the DROP. A re-run on a correct chain changes nothing. NestQuest's
+8080/8081 rules below them are left untouched.

+
+The unit is `Type=oneshot`, `RemainAfterExit=yes`, `Requires=` and
+`PartOf=docker.service`, and `WantedBy=multi-user.target docker.service`:
+it re-applies the rules whenever Docker starts or restarts (Docker
+recreates `DOCKER-USER` empty), and a failure fails this unit only.
+
+Install (done on 10.60.1.14 on 2026-10-05):
+
+```sh
+cd /home/overseer/mealquest
+sudo install -o root -g root -m 0755 deploy/systemd/mealquest-firewall.sh /usr/local/sbin/mealquest-firewall
+sudo install -o root -g root -m 0644 deploy/systemd/mealquest-firewall.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable --now mealquest-firewall
+```
+
+Check:
+
+```sh
+systemctl is-enabled mealquest-firewall; systemctl is-active mealquest-firewall   # enabled, active
+sudo iptables -S DOCKER-USER
+```
+
+Expected head of the chain (recorded 2026-10-05; NestQuest's rules follow):
+
+```

+-A DOCKER-USER -m conntrack --ctorigdst 10.60.1.14 --ctorigdstport 8090 --ctdir ORIGINAL -m comment --comment mealquest-firewall -j DROP
+```
+
+From any other LAN machine, `curl -m 5 http://10.60.1.14:8090/health` must
+time out; from 10.60.1.33 and 10.60.1.14 it returns 200.
+
+## Stack unit
+
+`deploy/systemd/mealquest.service` owns the compose stack and is the only
+way it starts. Both compose services use `restart: "no"`, so Docker never
+starts them on its own; the unit has `Requires=` and
+`After=mealquest-firewall.service`, so the stack starts only after the
+firewall rules are applied, and not at all if that unit fails. It is
+`PartOf=docker.service`, so restarting Docker (which recreates
+`DOCKER-USER` empty) stops the stack, re-applies the firewall, then starts
+the stack again. `ExecStart` is `docker compose … up -d` and `ExecStop` is
+`docker compose … down`; neither builds, so build before starting.
+
+Containers no longer restart after a crash; `systemctl restart mealquest`
+brings them back.
+
+| Repository file | Installed as |
+| --- | --- |
+| `deploy/systemd/mealquest.service` | `/etc/systemd/system/mealquest.service` (root, 0644) |
+
+Install (done on 10.60.1.14 on 2026-10-05):
+
+```sh
+cd /home/overseer/mealquest
+sudo install -o root -g root -m 0644 deploy/systemd/mealquest.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable --now mealquest
+```
+
+Check:
+
+```sh
+systemctl is-enabled mealquest; systemctl is-active mealquest   # enabled, active
+systemctl show mealquest -p Requires -p After                    # both list mealquest-firewall.service
+```
+
+Start, stop and restart the whole stack with `sudo systemctl start|stop|restart
+mealquest`, never with `docker compose up` or `down`. Per-service compose
+commands (`stop mealquest`, `up -d --force-recreate litestream`) are fine
+while the unit is active, because the firewall is already in place.
+
+## Recipe search (SearXNG)
+
+The `searxng` service in `deploy/compose.yaml` is a private SearXNG
+instance for recipe search. On the compose network it is reachable at
+`http://searxng:8080`; that is the address to configure in the app.
+
+Starting the sidecar does not connect the app to it. The recipe-search
+provider and base URL live in the `recipe_search_settings` row and are set
+through `GET`/`PATCH /api/v1/settings/recipe-search` (the API behind the
+recipe search card on Settings → AI assistant). Until that row exists,
+recipe search answers 409 `not_configured`.
+
+`deploy/compose.yaml` sets `MEALQUEST_SEARXNG_URL=http://searxng:8080`.
+The service only suggests it: `GET` returns it as `default_base_url`, and
+the recipe search card pre-fills the SearXNG URL with it while no URL is
+saved. Nothing is stored until the card is saved, and a saved `base_url`
+always wins. A set value must be an absolute `http://` or `https://` URL
+without credentials, a query or a fragment, or the service refuses to
+start; unset, `default_base_url` is `null`.
+
+To set it up, open Settings → AI assistant, check that the recipe search
+card shows SearXNG with `http://searxng:8080`, select **Save recipe search**
+and then **Test**. Or, from a signed-in session (every non-`GET` request
+needs the `X-MealQuest-CSRF` header set to `csrfToken` from
+`GET /api/v1/me`):
+
+1. `PATCH /api/v1/settings/recipe-search` with
+   `{"provider": "searxng", "base_url": "http://searxng:8080"}`.
+2. `GET /api/v1/settings/recipe-search` shows `"provider": "searxng"` and
+   `"base_url": "http://searxng:8080"`.
+3. `POST /api/v1/settings/recipe-search/test` searches
+   "chicken tikka masala" and must answer 200 with
+   `{"query": "chicken tikka masala", "count": <n>}`. A 502
+   `search_failed` carries SearXNG's error.
+
+| Item | Value |
+| --- | --- |
+| Image | `searxng/searxng:2026.10.4-d48c4b555`, pinned by digest `sha256:76b0bf285aca014c7191fc4d9234c4bfb358624ac33d8883833d496c059ec072` |
+| Settings | `deploy/searxng/settings.yml`, mounted read-only at `/etc/searxng/settings.yml` |
+| Secret | `deploy/secrets/searxng.env` (`SEARXNG_SECRET`), see "Secrets" |
+| Network | `mealquest` only; **no published port** |
+| Health | `wget http://127.0.0.1:8080/healthz` inside the container |
+
+The settings enable the `json` output format, turn off the public limiter
+and bot detection (the only client is the `mealquest` service), and keep
+only the general web search engines DuckDuckGo, Brave, Google, Bing,
+Mojeek and Startpage. Engines that block the host (CAPTCHA, "too many
+requests") are suspended by SearXNG for a while and listed under
+`unresponsive_engines` in the JSON; the others still answer.
+
+Check from inside the app container (the only place it is reachable):
+
+```sh
+docker compose -f deploy/compose.yaml exec mealquest \
+  wget -qO- 'http://searxng:8080/search?q=chicken+tikka+masala+recipe&format=json'
+docker compose -f deploy/compose.yaml port searxng 8080   # prints ":0": nothing published
+```
+
+On 2026-10-06 that query returned 17 results. From this host four of the
+six engines were blocked (Brave, DuckDuckGo, Google and Startpage were
+rate-limited or served a CAPTCHA), so the results came from Bing and
+Mojeek. SearXNG retries suspended engines after their suspension ends, so
+the set that answers can change. From 10.60.1.85 nothing on 10.60.1.14 answered as SearXNG:
+8888 refused the connection and 8080 is NestQuest's API.
+
+For development, `deploy/compose.dev.yaml` publishes SearXNG on the
+dev machine's loopback only (`127.0.0.1:8888`). It is never used on
+office-srvr.
+
+To move to a newer image, pull the new tag, take its digest from
+`docker image inspect --format '{{json .RepoDigests}}' searxng/searxng:<tag>`,
+update both in `deploy/compose.yaml`, then deploy as usual.
+
+## Routine deploy and rollback
+
+Production runs `main` (a release); only `overseer` merges `dev` → `main`.
+Every deploy builds the image on the host from the checked-out commit.
+
+### Deploy
+
+```sh
+cd /home/overseer/mealquest
+git fetch origin
+git rev-parse --short HEAD          # the SHA being replaced: note it for rollback
+git checkout --detach origin/main   # or a release tag
+docker compose -f deploy/compose.yaml build
+sudo systemctl restart mealquest    # applies the firewall, then down + up -d
+docker compose -f deploy/compose.yaml ps   # mealquest healthy, litestream up, searxng healthy
+curl -fsS http://10.60.1.14:8090/health
+curl -s -o /dev/null -w "%{http_code}\n" https://mealquest.cubecraftlabs.com/health   # 200
+git rev-parse HEAD                  # the deployed SHA
+```
+
+Record the deployed SHA, the previous SHA and the date in the Maestro task
+for the release. Migrations run at start-up; the service refuses to start
+if the database has an applied migration it does not know.
+
+If `deploy/.env.example` gained a variable, add it to `deploy/.env` before
+the restart; the service fails fast at boot naming any missing required variable.
+
+### Rollback to a previous SHA
+
+```sh
+cd /home/overseer/mealquest
+git checkout --detach <previous SHA>
+docker compose -f deploy/compose.yaml build
+sudo systemctl restart mealquest
+docker compose -f deploy/compose.yaml ps
+curl -fsS http://10.60.1.14:8090/health
+```
+
+A rollback across a release that added a migration fails at start-up
+(the older binary refuses the newer schema). In that case restore the
+database to a point before the upgrade — "Restore the database" with
+`-timestamp` set just before the deploy — then start the older SHA.
+Changes made since that point are lost; say so to the household.
+
+## Backups
+
+### Database — Litestream
+
+The `litestream` compose service streams every committed change to
+`mealquest.db` to the NAS over SFTP (`deploy/litestream.yml`). It takes a
+full snapshot daily (compaction level 9) and keeps a week of snapshots
+plus the incremental LTX files between them.
+
+One-time setup (already done on 10.60.1.14):
+
+1. Generate the dedicated keypair, git-ignored, owned by the container
+   user:
+
+   ```sh
+   cd /home/overseer/mealquest
+   ssh-keygen -t ed25519 -N '' -C mealquest-litestream -f deploy/secrets/litestream_key
+   # append deploy/secrets/litestream_key.pub to joshua@10.60.1.50:~/.ssh/authorized_keys
+   rm deploy/secrets/litestream_key.pub
+   sudo chown 10001:10001 deploy/secrets/litestream_key
+   sudo chmod 0600 deploy/secrets/litestream_key
+   ```
+
+2. The NAS host key is pinned in `deploy/litestream.yml` (`host-key`).
+
+Check replication — list every LTX file at every level. Level 9 holds the
+full snapshots; the default listing (`-level 0`) shows only L0 files:
+
+```sh
+docker compose -f deploy/compose.yaml exec -T litestream \
+  litestream ltx -config /etc/litestream.yml -level all /data/mealquest.db
+```
+
+### Media — nightly rsync
+
+`mealquest-media-backup.timer` runs `mealquest-media-backup.service` at
+03:30 every night. The service runs `/usr/local/sbin/mealquest-media-backup`
+(`deploy/systemd/mealquest-media-backup.sh`) as the unprivileged host user
+`mealquest` (uid/gid 10001, the app's own user) with no capabilities.
+systemd bind-mounts the data volume read-only at `/run/mealquest-data` and
+passes the Litestream key in as the credential `nas_key`; uid 10001 cannot
+otherwise reach `/var/lib/docker` or `deploy/secrets/`. The script refuses a
+`media` path that is a symlink and fails (exit 1) if `media` is missing.
+
+One-time setup (already done on 10.60.1.14):
+
+```sh
+cd /home/overseer/mealquest
+# Host user for the backup; ssh needs a passwd entry for its uid.
+sudo groupadd --system --gid 10001 mealquest
+sudo useradd --system --uid 10001 --gid 10001 --no-create-home \
+  --home-dir /nonexistent --shell /usr/sbin/nologin mealquest
+# Pinned NAS host keys, root-owned and world-readable.
+sudo install -d -o root -g root -m 0755 /etc/mealquest
+sudo install -o root -g root -m 0644 deploy/known_hosts /etc/mealquest/known_hosts
+# The media directory; the backup fails if it is ever missing.
+sudo install -d -o 10001 -g 10001 -m 0755 /var/lib/docker/volumes/mealquest-data/_data/media
+# Script and units.
+sudo install -o root -g root -m 0755 deploy/systemd/mealquest-media-backup.sh /usr/local/sbin/mealquest-media-backup
+sudo install -o root -g root -m 0644 deploy/systemd/mealquest-media-backup.service \
+  deploy/systemd/mealquest-media-backup.timer /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable --now mealquest-media-backup.timer
+```
+
+Run it by hand and read the result:
+
+```sh
+sudo systemctl start mealquest-media-backup.service
+journalctl -u mealquest-media-backup --no-pager -n 30
+```
+
+To restore media, follow "Restore photos (media)" — never copy back while
+the timer or the service can still run.
+
+## Restore the database
+
+SQLite in WAL mode keeps recent commits in `mealquest.db-wal`, indexed by
+`mealquest.db-shm`. **A restored database must never sit beside an old WAL
+or shared-memory file**: on open, SQLite would replay the old WAL's pages
+onto the restored database and corrupt it or mix in state from the
+database it replaced. So all three files are moved aside together, with
+Litestream's local state directory `.mealquest.db-litestream`, before the
+restore — and the restore runs into an empty volume.
+
+Run from `/home/overseer/mealquest`:
+
+```sh
+D=/var/lib/docker/volumes/mealquest-data/_data
+A=/var/tmp/mealquest-restore-aside-$(date +%Y%m%d%H%M)
+
+# 1. Stop the whole stack (app and Litestream). Nothing may hold the
+#    database open; a clean close checkpoints the WAL into mealquest.db.
+sudo systemctl stop mealquest
+
+# 2. Move the database, its -wal and -shm files and Litestream's state
+#    aside — all of them, every time. Keep the directory until the
+#    restored stack is verified.
+sudo mkdir "$A"
+for f in mealquest.db mealquest.db-wal mealquest.db-shm .mealquest.db-litestream; do
+  if sudo test -e "$D/$f"; then sudo mv "$D/$f" "$A/"; fi
+done
+sudo ls -la "$D"   # must list only media/
+
+# 3. Restore from the NAS. --no-deps keeps the app stopped so it cannot
+#    create a fresh, empty database first.
+docker compose -f deploy/compose.yaml run --rm --no-deps litestream \
+  restore -config /etc/litestream.yml -o /data/mealquest.db /data/mealquest.db
+sudo ls -la "$D"   # mealquest.db only: no -wal, no -shm
+
+# 4. Check the restored file before starting the app (see "Count check").
+
+# 5. Start the stack and check health.
+sudo systemctl start mealquest
+docker compose -f deploy/compose.yaml ps
+curl -s -o /dev/null -w "health %{http_code}\n" http://10.60.1.14:8090/health
+```
+
+To restore to a point in time, add `-timestamp 2026-10-05T23:00:00Z` (or
+`-txid`) to the `restore` command.
+
+### Count check
+
+`/tmp/mqcount.py` prints row counts for key tables, the number of
+application tables, a SHA-256 over every application row (first 16 hex
+digits; Litestream's own `_litestream*` tables are excluded) and
+`PRAGMA integrity_check`. Run it on a **copy** of the database, never on the
+live file; copy `-wal`/`-shm` along with it when the app is running.
+
+```python
+import sqlite3, sys, hashlib
+c = sqlite3.connect(sys.argv[1])
+tabs = [r[0] for r in c.execute("select name from sqlite_master where type=\"table\" and name not like \"sqlite_%\" and name not like \"_litestream%\" order by name")]
+for t in ("dinners", "week_plans", "schema_migrations"):
+    print(t, c.execute(f"select count(*) from {t}").fetchone()[0])
+h = hashlib.sha256()
+for t in tabs:
+    for row in c.execute(f"select * from \"{t}\" order by rowid"):
+        h.update(repr(row).encode())
+print("tables", len(tabs), "content-sha256", h.hexdigest()[:16])
+print("integrity", c.execute("pragma integrity_check").fetchone()[0])
+```
+
+```sh
+rm -rf /tmp/mqcheck && mkdir /tmp/mqcheck
+sudo sh -c "cp -a $D/mealquest.db* /tmp/mqcheck/" && sudo chown -R "$USER" /tmp/mqcheck
+python3 /tmp/mqcount.py /tmp/mqcheck/mealquest.db
+```
+
+Before and after must match exactly.
+
+## Restore photos (media)
+
+Recipe and dinner photos live in `media/` in the data volume and are
+backed up nightly to `joshua@10.60.1.50:/volume1/homes/Joshua/mealquest-backups/media/`
+(see "Media — nightly rsync"). The backup service mirrors with
+`rsync --delete`. **An `rsync --delete` run must never see an empty or
+partial `media/`**: it would delete the NAS copy you are about to restore
+from. Stopping the timer is not enough — it does not stop a run that is
+already in flight, and the service can still be started by hand. So stop
+**both** the timer and the service, confirm no rsync is running, and do
+not start the service until the restore is verified.
+
+Run from `/home/overseer/mealquest`:
+
+```sh
+M=/var/lib/docker/volumes/mealquest-data/_data/media

+sudo $SSH joshua@10.60.1.50 "find $NAS -type f | wc -l"   # unchanged from step 2
+

+
+The local count may exceed the NAS count only if `media/` still held
+files the NAS never received (photos added since the last nightly run);
+the next nightly run then copies them up. If the local count is lower,
+the copy did not complete: leave the timer stopped and re-run step 5.
+
+When the database is restored too, restore it first ("Restore the
+database"), then the media, so every photo the database refers to is
+present. This media restore has not been run against production yet; the
+backup direction was checked on 2026-10-05 (see "Media backup checks").

+1. `docker compose -f deploy/compose.yaml down` — both containers stopped
+   and removed. The volume then held `mealquest.db`,
+   `.mealquest.db-litestream/` and `media/`; the clean close had
+   checkpointed and removed `-wal` and `-shm`.
+2. Before (copy of the stopped database):
+

+
+3. Moved aside to `/var/tmp/mealquest-restore-aside-20261005`:
+   `mealquest.db` and `.mealquest.db-litestream` (no `-wal`/`-shm` existed
+   after the clean stop; the loop moves them whenever they do). Volume
+   afterwards: `media/` only.
+4. `docker compose -f deploy/compose.yaml run --rm --no-deps litestream restore -config /etc/litestream.yml -o /data/mealquest.db /data/mealquest.db`
+   — volume afterwards: `mealquest.db` (258048 bytes) and `media/`; no
+   `-wal`, no `-shm`.
+5. After (copy of the restored file, before the app started):
+

+
+6. `docker compose -f deploy/compose.yaml up -d` — `mealquest-mealquest-1`
+   healthy, `mealquest-litestream-1` up; `GET /health` → `200`. Counts on a
+   copy of the running database (`mealquest.db`, `-wal`, `-shm`) were
+   identical to the above.
+7. Litestream resumed against the restored database:

+
+## Secret rotation
+
+Rotate a secret when it may have leaked, when someone with access leaves,
+or on the owner's schedule. Never paste a secret into a ticket, chat or
+this file.
+
+### App key (`deploy/secrets/secret_key`)
+
+The app key encrypts every stored secret: the `_ct` columns
+`ai_settings.api_key_ct` (LLM API key), `recipe_search_settings.api_key_ct`
+(recipe-search API key), `integrations_google.refresh_token_ct` (Google
+Calendar refresh token) and `chat_settings.webhook_url_ct` (Google Chat
+webhook URL). **Rotating it re-encrypts nothing**: a value encrypted with
+the old key can no longer be read. A `mealquest rotate-key` helper that
+re-encrypts in place is planned but does not exist yet.
+
+**What is recoverable today.** The service currently exposes only
+household settings; no shipped flow writes or re-enters any of these four
+secrets. The re-entry flows are planned: the LLM key in Settings → AI
+assistant (the AI settings feature), the recipe-search key (Feature 10),
+Google Calendar reconnect (Feature 16) and the Google Chat webhook
+(Feature 19). So today the rotation is safe **only if no `_ct` value is
+stored**, which the pre-check below proves. If the pre-check finds a
+stored value, do not rotate: it could not be re-entered afterwards. Keep
+the current key and wait for the matching flow (or the `rotate-key`
+helper).
+
+**The pre-check and the key replacement run with the whole stack
+stopped**, from the pre-check until the new key is in place. A raw copy of
+`mealquest.db` and `mealquest.db-wal` taken while the stack runs is **not**
+a consistent snapshot: the two files are copied one after the other, and a
+checkpoint (by the app or by Litestream) between the two copies can move
+committed pages out of the WAL into `mealquest.db` after `mealquest.db` was
+already copied, then reset the WAL before it is copied. The copy then
+lacks those commits — possibly a stored `_ct` value — and the pre-check
+reports a false 0. A running app could also store a `_ct` value after a
+correct pre-check and before the key is replaced. Stopping both containers
+removes every writer (Litestream also writes and checkpoints), and the
+clean close checkpoints the WAL into `mealquest.db`, so the file alone is
+complete.
+
+Run from `/home/overseer/mealquest`:
+
+```sh
+D=/var/lib/docker/volumes/mealquest-data/_data
+
+# 1. Stop the whole stack (app and Litestream) and leave it stopped until
+#    step 4. Nothing may hold the database open.
+sudo systemctl stop mealquest
+sudo ls -la "$D"   # mealquest.db and media/ only: no -wal, no -shm; if
+                   # either exists, the close was not clean — stop here
+
+# 2. Pre-check, on a copy of the now-quiescent database.
+rm -rf /tmp/mqcheck && mkdir /tmp/mqcheck
+sudo cp -a "$D/mealquest.db" /tmp/mqcheck/ && sudo chown -R "$USER" /tmp/mqcheck
+python3 - /tmp/mqcheck/mealquest.db <<'PY'
+import sqlite3, sys
+c = sqlite3.connect(sys.argv[1])
+for t, col in (("ai_settings", "api_key_ct"), ("recipe_search_settings", "api_key_ct"),
+               ("integrations_google", "refresh_token_ct"), ("chat_settings", "webhook_url_ct")):
+    print(t, col, c.execute(f"select count(*) from {t} where {col} is not null").fetchone()[0])
+PY
+rm -rf /tmp/mqcheck
+# every count must be 0; otherwise start the stack again on the current
+# key (sudo systemctl start mealquest) and stop here
+
+# 3. Replace the key, still with the stack stopped.
+sudo cp -a deploy/secrets/secret_key /var/tmp/secret_key.old   # keep until verified, then shred
+head -c 32 /dev/urandom | base64 | sudo tee deploy/secrets/secret_key >/dev/null
+sudo chown 10001:10001 deploy/secrets/secret_key
+sudo chmod 600 deploy/secrets/secret_key
+
+# 4. Start the stack on the new key and check health.
+sudo systemctl start mealquest
+docker compose -f deploy/compose.yaml ps
+curl -fsS http://10.60.1.14:8090/health
+```
+
+Then sign in and open household settings to confirm the service runs on
+the new key. Finally `sudo shred -u /var/tmp/secret_key.old`. Once the
+planned flows ship, this section gains a step per secret to re-enter it
+and confirm it works.
+
+### OIDC client secret (`deploy/secrets/oidc_client_secret`)
+
+In Authentik, open the provider `mealquest` and regenerate the Client
+Secret. Write it to the file (same owner and mode as above) and recreate
+the service:
+
+```sh
+printf '%s\n' '<new Authentik client secret>' | sudo tee deploy/secrets/oidc_client_secret >/dev/null
+sudo chown 10001:10001 deploy/secrets/oidc_client_secret
+sudo chmod 600 deploy/secrets/oidc_client_secret
+docker compose -f deploy/compose.yaml up -d --force-recreate mealquest
+```
+
+Sign in at <https://mealquest.cubecraftlabs.com> to confirm; sign-ins
+fail between regenerating the secret in Authentik and recreating the
+service.
+
+### LLM API key
+
+Stored encrypted in the database, not in `deploy/`. In the app, open
+**Settings → AI assistant**, choose **Replace**, paste the new key and
+**Verify**, and check the verified state is shown. Then revoke the
+old key in the provider's console. (The AI assistant settings page is
+delivered by its own feature; until it ships there is no stored LLM key
+to rotate.)
+
+### VAPID keys (Web Push)
+
+Planned with Web Push (Feature 19): the public key goes in
+`deploy/.env` as `MEALQUEST_VAPID_PUBLIC_KEY`, the private key in
+`deploy/secrets/vapid_private_key` (owner `10001:10001`, mode 0600), and
+the pair is generated with `cmd/vapidgen`. **Changing the VAPID pair
+invalidates every push subscription**: each device must turn
+notifications on again (`/settings/notifications`) before it receives
+pushes. Rotate only when the private key may have leaked, write both
+halves, recreate the service with `--force-recreate mealquest`, and tell
+the household to re-enable notifications on each device.
+
+### SearXNG secret (`deploy/secrets/searxng.env`)
+
+Only signs SearXNG's own cookies and image-proxy links; nothing stored
+depends on it. Replace it and recreate the service:
+
+```sh
+(umask 077; printf 'SEARXNG_SECRET=%s\n' "$(openssl rand -hex 32)" > deploy/secrets/searxng.env)
+docker compose -f deploy/compose.yaml up -d --force-recreate searxng
+docker compose -f deploy/compose.yaml ps searxng   # healthy
+```
+
+### Litestream / NAS key (`deploy/secrets/litestream_key`)
+
+Generate a new keypair as in "Database — Litestream", add the new public
+key to `joshua@10.60.1.50:~/.ssh/authorized_keys`, replace the file
+(owner `10001:10001`, mode 0600), run
+`docker compose -f deploy/compose.yaml up -d --force-recreate litestream`
+and `sudo systemctl start mealquest-media-backup.service`, check both
+(`litestream ltx` and the journal), then remove the old public key from
+the NAS.
+
+## Context records
+
+The confirmed values in this runbook (port 8090, checkout path, Authentik
+group `mealquest-admin`, DNS, firewall, backup target) are also recorded in
+the CTXD project `mealquest`: `RUNBOOKS.MD` (deployment procedure) and the
+open questions in `CONTEXT.MD`, updated for Feature 07 task 876134bc.

+  Responses also carry the read-only `default_base_url`, the deployment's
+  `MEALQUEST_SEARXNG_URL` (or null), which the client pre-fills while no
+  base_url is saved; only a PATCH of base_url stores a URL.
   `POST /api/v1/settings/recipe-search/test` searches "chicken tikka
   masala" and returns `{query, count}`, 409 `not_configured`, or 502
   `search_failed` with the provider's error.
+- `GET`/`PATCH /api/v1/settings/ai` (`aisettings.Service`) — provider,
+  base_url, model, temperature, system_prompt, plus the read-only
+  `api_key_last4` and `key_verified_at`. PATCH requires a preset name as
+  provider, temperature 0–1 in 0.1 steps, a non-empty model and a
+  system_prompt of at most 8000 characters; a fixed-URL preset's base_url
+  must be empty or its own. Provider and base_url cannot change while a
+  key is stored (remove the key first), so a stored key is never sent to
+  an endpoint it was not stored for.
+  `PUT /api/v1/settings/ai/api-key` takes `{api_key}` (write-only, at least
+  8 characters, sealed with the secret box; an empty string removes it) and
+  clears `key_verified_at`; a preset without a fixed base_url takes a key
+  only when its base_url passes `secureurl.Check`. `POST /api/v1/settings/ai/verify` calls
+  `Provider.Verify` and records `key_verified_at`;
+  `GET /api/v1/settings/ai/models` returns `{models: [{id, display_name}]}`
+  live from the provider, with the key redacted from every id and
+  display_name. Both work before a model is chosen
+  (`presets.ForAccount`), answer 409 `not_configured` when the settings
+  cannot build a provider, and 502 with the provider's typed error
+  (`auth_failed`, `rate_limited`, `bad_output`, `provider_error`; 504
+  `timeout`) when the call fails. `POST /api/v1/settings/ai/reset-prompt`
+  restores `household.DefaultPersonaPrompt` (CTXD PROMPTS.MD §4). No
+  response holds the key. `Service.HarnessConfig` reads the settings for
+  each skill run, so a saved change applies to the next run.
+- Dinners (`dinners.Service`). `POST /api/v1/dinners` adds a Regular from
+  `{name}` or `{name, recipe_url}` (an https:// link, kept in
+  `recipe_url` for grounding and never returned in a dinner response, as
+  it may carry a personal token) with status and origin `regular` and
+  grounding_status `pending`, answering 201 with the dinner. The name is
+  always the household's: no part of a link is ever used as a dinner's
+  name, and a link without a name is 400. A name
+  is trimmed, at most 120 characters and must keep a word after
+  `harness.Normalize`, which sets `normalized_name`. A name
+  `harness.Similar` to an unarchived dinner's, or a link one already has
+  (the source_url of the recipe it is grounded in, else its pasted
+  `recipe_url`), is 409 `duplicate_dinner`; archived names may be added
+  again.
+  `GET /api/v1/dinners?status=regular|quest_log` returns
+  `{dinners: [...]}` ordered by normalized name, each with `photo_url`
+  (`/media/photos/{photo_id}-400.jpg`, or null) and `grounding_status`;
+  any other status is 400. The Quest log (`quest_log`) is the dinners
+  accepted and not yet scheduled: one on the plan for the household's
+  current week (by its timezone) or a later week is left out. `PATCH /api/v1/dinners/{id}` edits `name`
+  (deduplicated against the other unarchived dinners), `method`
+  (`stovetop` / `oven` / `crockpot` / `grill` / `other`), `minutes_total`
+  (1–1440) and `difficulty` (`easy` / `medium` / `hard`); invalid values
+  are 400 `invalid_dinner` and change nothing. `DELETE /api/v1/dinners/{id}`
+  sets status `archived` and keeps the row; `POST
+  /api/v1/dinners/{id}/favorite` toggles `is_favorite`. Every write records
+  the session's subject as `updated_by`; an unknown id is 404.
+- Dinner grounding. `POST /api/v1/dinners` also enqueues a `ground_dinner`
+  job and answers with its `grounding_job_id` without waiting for it
+  (`GET /api/v1/jobs/{id}` reports it); if the job cannot be enqueued it
+  still answers 201, with grounding_status `failed` (`grounding_error`)
+  and `grounding_job_id` null. The job grounds the dinner's
+  `recipe_url` directly with `GroundURL`, else its name with `Ground`
+  (see Recipe grounding), and sets grounding_status `grounded` with the
+  recipe's recipe_id, photo_id, method, minutes_total and difficulty, or
+  `failed` with `grounding_error` — also the job's failure code — one of
+  `no_recipe_found`, `recipe_unusable` (the pasted link), `search_not_configured`,
+  `search_failed`, `ai_failed`, `interrupted` (the server stopped) or
+  `grounding_error`. Each job carries the dinner's `grounding_revision`
+  from when it was enqueued; renaming a `pending` dinner clears its
+  `recipe_url`, raises the revision and enqueues a job for the new name.
+  A job for a dinner archived, no longer `pending` or at another revision
+  does no work, and a job only writes a dinner still unarchived, `pending`
+  and at its revision, so a fix-up made meanwhile wins and an earlier job
+  for an old name — queued or running — never decides the outcome.
+  Archiving or renaming a dinner also stops its running job where it is,
+  so no further search, page fetch, photo download or model call is made
+  for it. A
+  method, minutes_total or difficulty a member saved while the dinner was
+  `pending` is kept; grounding fills only those left empty. At boot, after
+  the job runner fails the jobs a previous process left running, every
+  unarchived dinner still `pending` with no `ground_dinner` job for its revision
+  queued or running is set `failed` with `interrupted`, so no dinner stays
+  pending with nothing left to ground it.
+  `GET /api/v1/dinners/{id}/recipe-candidates`
+  searches for the dinner's name and returns `{candidates: [{candidate_id,
+  title, site_name, photo_url, minutes}]}`, at most 3, ranked as `Ground`
+  ranks them; it fetches pages but downloads no photo and runs no model,
+  so `photo_url` is set only for a page already stored, and `candidate_id`
+  is the page's URL. `POST /api/v1/dinners/{id}/ground` takes exactly one
+  of `{candidate_id}`, `{recipe_url}` (both grounded with `GroundURL`,
+  setting `grounded`) or `{manual: {ingredients[], steps[], minutes,
+  method}}` (1–100 ingredient lines, up to 100 steps, each non-blank and at
+  most 500 characters; minutes 1–1440). A manual recipe is stored as typed
+  — no model runs — as a `recipes` row whose source_url is
+  `mealquest:manual:{recipe_id}` and whose raw_jsonld is a schema.org
+  Recipe built from it, and sets `manual` with its method and minutes, no
+  photo and the dinner's difficulty unchanged. Either clears the dinner's
+  pasted `recipe_url`: the recipe chosen replaces it. It answers 200 with
+  the dinner; an invalid body is 400, an unknown dinner 404, a page that cannot
+  ground it 422 `ungroundable` (the dinner is unchanged), recipe search not
+  set up 409 `not_configured`, a search or model failure 502
+  `search_failed` / `ai_failed` (only the reason code is logged, never the
+  provider's text), and grounding a candidate or link that runs past 90
+  seconds (fetch, photo and `normalize_recipe`, all in the request) 504
+  `ground_timeout`, leaving the dinner unchanged. An archived dinner is 409
+  `dinner_archived`. A candidate or link is written only if the dinner is
+  still as it was before grounding began: one renamed or grounded some
+  other way meanwhile is 409 `ground_conflict`, and one archived meanwhile
+  409 `dinner_archived`, either leaving the dinner unchanged. A method,
+  minutes or difficulty a member edits meanwhile is kept over the recipe's.
+  Any other failure grounding a candidate or link, or recording it on the
+  dinner, is 500, logged with a fixed reason and the dinner id only —
+  never the link, which can carry a personal token, or dependency error
+  text.
+- Side quest suggestions (`suggest.Service`). `POST
+  /api/v1/suggestions/batches` creates a `manual` batch and enqueues its
+  `suggestion_batch` job, answering 202 `{batch_id, job_id, trigger,
+  status}` without waiting; while a batch is `pending` or `running` it
+  answers 202 with that batch instead, so at most one runs at a time (the
+  check, the batch and its job share one write transaction). The job reads the
+  household context, the deck's names and every declined name, runs
+  `suggest_side_quests` for 5 Side quests (scope: the batch id), then
+  grounds the survivors in the model's order with `Grounder.GroundMany`,
+  as many as are still wanted at a time, until 5 are kept or none are
+  left. A Side quest no recipe grounds is dropped; each round's grounded
+  ones are stored before the next — a dinner with status `suggested`,
+  origin `side_quest`, grounding_status `grounded` with the recipe's
+  recipe_id, photo_id, method, minutes_total and difficulty and the
+  model's cuisine, and a `pending` suggestion with the name it is
+  suggested under, the reason and `cited_regular_ids` — unless, since the
+  job read its input, a dinner it repeats was added, a suggestion it
+  repeats passed, or a Regular it cites renamed or archived (checked in
+  the storing transaction). The job publishes
+  `{batch_id, stage, suggestion_ids, dropped}` as it goes (`suggesting`,
+  `grounding`, `done`). It fails with `no_regulars`, `ai_failed` (the
+  skill or `normalize_recipe` failed; no Side quest is made up instead,
+  D-017), `search_not_configured` or `search_failed`, and the batch is set
+  `failed`; Side quests stored before the failure stay in the deck. If
+  recording the batch's end fails, its job fails; the job runner retries
+  a job's final status write with backoff until it lands, each attempt
+  bounded at 5 seconds; at shutdown an attempt that fails or times out is
+  not retried, and the next start fails the job as interrupted. Recording
+  the batch's end is bounded the same way (one attempt, 5 seconds, made
+  even during shutdown), so a busy writer cannot hold a stopping worker;
+  a batch whose end timed out is left `running` with its job. Each time a
+  batch is started, before the active batch is selected, every batch
+  still `pending` or `running` with no job queued or running (the process
+  stopped, or recording its end failed) is set `failed`, so it does not
+  block the next.
+  `GET /api/v1/suggestions/deck` returns `{suggestions: [{id, dinner_id,
+  name, photo_url, difficulty, method, minutes_total, cuisine, reason,
+  cited_regular_ids, status, dinner_status, decided_at, created_at}]}`:
+  the `pending` suggestions whose dinner is still `suggested`, oldest
+  first. `POST /api/v1/suggestions/{id}/accept` (Try it) sets the
+  suggestion `accepted` and moves its dinner to `quest_log`; `POST
+  /api/v1/suggestions/{id}/decline` (Pass) sets it `declined` and archives
+  the dinner; every later batch, and the household context's passed list,
+  reads the suggestion's own name as declined, so renaming the archived
+  dinner changes nothing. Both record
+  the session's subject as the dinner's `updated_by` and answer 200
+  `{suggestion, replenish_job_id}`. Repeating a decision changes nothing
+  and answers 200; the opposite decision is 409 `suggestion_decided`, a
+  suggestion whose dinner left the deck some other way 409
+  `dinner_not_suggested`, and an unknown id 404. A decision that leaves

+First run: while `household_settings.onboarding_completed_at` (read from
+`GET /api/v1/settings/household`) is null, every route redirects to
+`/onboarding`. Onboarding is a full screen outside the app shell, in three

+waits for three saved Regulars, and a common pick is not offered once a
+Regular has a name `harness.Similar` to it — the PWA's copy of the name
+rules in `web/src/dinners/names.ts` folds letters with
+`web/src/dinners/letterFolds.json`, which `gen_folds.py` writes from the
+same table as the server's, and runs the same cases,
+`internal/ai/harness/testdata/dedupe_cases.json`, as the server's) and
+notifications (`/onboarding/notifications`: what MealQuest notifies about,
+the iOS install hint, "Turn on notifications" and "Maybe later"). Either
+button sends `PATCH /api/v1/settings/household` with
+`{"onboarding_completed": true}`; the server sets `onboarding_completed_at`
+to the time of that update (keeping the first time if it is already set;
+the field itself is read-only and `false` is refused) and the app goes Home.
+Completing needs at least three Regulars (`household.MinRegulars`); with
+fewer the server answers 400 `invalid_settings` naming
+`onboarding_completed` and changes nothing. Step 3 can be reached with
+fewer — by its URL, or after another member removes a Regular — so it then
+shows the server's reason with an "Add Regulars" button back to step 2.
+Notification permission is never asked for on page load; until Feature 19
+wires Web Push, "Turn on notifications" asks for nothing. Offline on the saved pages the
+settings cannot be read (the service worker never caches `/api/v1/settings`),
+so the saved pages open as they are.
+
+Regular dinners (`/settings/regulars`) lists the Regulars from
+`GET /api/v1/dinners?status=regular`, each with its photo, "method ·
+minutes", favorite heart and grounding badge ("Finding recipe…" while
+`pending`, "Recipe found" when `grounded` or `manual`, "Needs a recipe" when
+`failed`). The add field takes a name or a pasted `https://` recipe link.
+Tapping a Regular opens an edit sheet (name, method, minutes, difficulty;
+remove archives it after a confirmation); tapping one that needs a recipe
+opens "Fix recipe" (pick one of the recipe candidates, paste a link or type
+the ingredients and steps in). Adds, removals and the heart show at once and
+are undone if the server refuses them. While any Regular is `pending`, the
+list is read again every 3 seconds (not while a change is in flight), and
+polling stops once none is.

+You suggest Side quests: new dinners for the household to try, based on the dinners it already makes.
+
+Every Side quest must be a dinner the household has not had: never one of its Regulars, its Quest log, its pending Side quests or the dinners it has passed, and never one of those under another name. Base every Side quest on one or more of the household's Regulars, such as a familiar protein in a new cuisine or familiar flavours cooked a new way. Prefer the favorite Regulars, and vary the cuisines across the batch.
+
+Give for each Side quest:
+- name: the dinner's usual name, as a recipe site would title it.
+- cuisine: its cuisine, e.g. "Thai" or "Tex-Mex".
+- method: how it is mainly cooked: "stovetop", "oven", "crockpot" (slow cooker or crock pot), "grill" or "other".
+- est_minutes: your estimate of the whole minutes from starting prep to the table.
+- difficulty: "easy", "medium" or "hard" for a home cook.
+- reason: one sentence of at most 180 characters saying why the household would like it. It must name at least one of the Regulars in cited_regulars.
+- cited_regulars: the Regulars the reason relies on, at least one, each written exactly as its name appears in the Regulars list of the household context, without the details in parentheses. Cite only Regulars from that list.
+- search_query: a web search query that finds a recipe for this dinner.
+
+One valid Side quest, for a household with a Regular named "Chicken Fajitas" (an example only, not about this household):
+{"name": "Chicken Shawarma Bowls", "cuisine": "Middle Eastern", "method": "oven", "est_minutes": 40, "difficulty": "easy", "reason": "Spiced roast chicken and crisp toppings, like your Chicken Fajitas with a Middle Eastern twist.", "cited_regulars": ["Chicken Fajitas"], "search_query": "chicken shawarma bowls recipe"}

+## Instructions
+You suggest Side quests: new dinners for the household to try, based on the dinners it already makes.
+
+Every Side quest must be a dinner the household has not had: never one of its Regulars, its Quest log, its pending Side quests or the dinners it has passed, and never one of those under another name. Base every Side quest on one or more of the household's Regulars, such as a familiar protein in a new cuisine or familiar flavours cooked a new way. Prefer the favorite Regulars, and vary the cuisines across the batch.
+
+Give for each Side quest:
+- name: the dinner's usual name, as a recipe site would title it.
+- cuisine: its cuisine, e.g. "Thai" or "Tex-Mex".
+- method: how it is mainly cooked: "stovetop", "oven", "crockpot" (slow cooker or crock pot), "grill" or "other".
+- est_minutes: your estimate of the whole minutes from starting prep to the table.
+- difficulty: "easy", "medium" or "hard" for a home cook.
+- reason: one sentence of at most 180 characters saying why the household would like it. It must name at least one of the Regulars in cited_regulars.
+- cited_regulars: the Regulars the reason relies on, at least one, each written exactly as its name appears in the Regulars list of the household context, without the details in parentheses. Cite only Regulars from that list.
+- search_query: a web search query that finds a recipe for this dinner.
+
+One valid Side quest, for a household with a Regular named "Chicken Fajitas" (an example only, not about this household):
+{"name": "Chicken Shawarma Bowls", "cuisine": "Middle Eastern", "method": "oven", "est_minutes": 40, "difficulty": "easy", "reason": "Spiced roast chicken and crisp toppings, like your Chicken Fajitas with a Middle Eastern twist.", "cited_regulars": ["Chicken Fajitas"], "search_query": "chicken shawarma bowls recipe"}
+
+## Household context
+### Today
+- Tuesday 2026-10-06 (America/New_York)
+
+### Regulars
+- Beef Chili (Tex-Mex, crockpot, 240 min)
+- Chicken Fajitas (Tex-Mex, stovetop, 30 min, favorite)
+- Spaghetti Bolognese (Italian, stovetop, 45 min)
+
+### Quest log
+- Pad Thai
+
+### Passed, oldest first
+- Chicken Tikka Masala
+
+### Recent plans
+- 2026-10-05 Mon: Chicken Fajitas
+- 2026-10-06 Tue: Beef Chili
+
+### Pending Side quests
+- Shrimp Scampi
