# Runbook Sources of truth: `docker-compose.yml`, `main/check.sh`, `main/docs-check.sh`, `main/app/cli.py`, `main/alembic/`, `backups/`, rian's crontab. How to work on, check, deploy, and recover the app. Rules live in `agents.md`; this file is the procedure. Nothing here is a status: for what is running, ask the app (`/api/health`, `/api/stats`, `python -m app.cli status`). ## Open a session Always from the workspace root, which is where the checkpoint hook and the project commands find `.logs/`: `claude`. Rian's shortcut: ```bash alias dfp='cd /srv/apps/dutyfreeprofessor && claude' ``` A session opened in the old WordPress folder writes no diary; that folder's `CLAUDE.md` redirects here. ## The dev loop - Python lives in `.venv-dev/` at the workspace root; the frontend in `main/web/` (Node is build-time only in production). - **Dev database:** the `dfp-devdb` container on `127.0.0.1:5433`. Point `DATABASE_URL` at it for any local run and for every migration rehearsal. **Never run a migration against the live database** (`dutyfreeprofessor-db`, reachable only inside the compose network). - Local API: from `main/`, `../.venv-dev/bin/uvicorn app.main:app --reload` with `DATABASE_URL` set to the dev database; the SPA dev server is `npm run dev` in `main/web/`. - **Before every commit and every deploy:** `main/check.sh`. It runs the pure-logic tests, regenerates the typed API client from the backend's OpenAPI schema, typechecks the SPA against it, and runs the doc gates (`main/docs-check.sh`). Seconds, not the minutes a Docker build takes to find the same error. - Tests are the bugs that shipped: `main/tests/README.md`. ## Migrations `alembic heads` must show one head before you write one. Migrations are schema-only (create tables, add nullable columns or columns with a `server_default`); every backfill is an idempotent `python -m app.cli` command run after the deploy, never Python inside Alembic. The container runs `alembic upgrade head` on start (see the Dockerfile `CMD`), so a deploy applies whatever is at head. Ownership order for the current wave: build plan §2. After a deploy carrying migration #1 (`0a1b2c3d4e5f`), run the backfills it expects, in this order, each safe to repeat: `backfill accounts`, `vertical`, `stuck_runs`, `locations`, `orphan_tiles`, `image_provenance`. Each prints one line saying what it changed. After a deploy carrying migration #3 (`f3a4b5c6d7e8`), in this order, each safe to repeat and each rehearsed twice on a copy of the dump: `backfill implausible_sizes`, `backfill brands`, `backfill sizes`, `backfill categories`, `rederive`, `backfill merges`. Run them with no collection in progress: `rederive` re-keys every product and `merges` re-points listings. After 0.34.0: `backfill perfume` (renames the stored category Fragrance to Perfume; it has run on the live database, and a second run reports zero). After a deploy carrying migration #4 (`b5c6d7e8f9a0`, the account system), in this order, each safe to repeat and each rehearsed twice on a copy of the dump: `backfill accounts` (the seeded owner row gains its username), `backfill levels` (the two launch levels, insert if absent), then the account commands under Accounts below, then `backfill authors --map Adam=adam --map Mark=mark --map rian=rian` (links typed comment and to-do names to the three accounts; add `--include-defaulted` only to link the two tables where the page defaulted an anonymous actor to a name), and `backfill overrides` (reports what exists; writes nothing). Every backfill takes `--check` to print what a run would change and write nothing. Other commands, all `python -m app.cli ...` inside the container: `awards --rebuild [--file]` (re-match competition medals from `import/winners.json`; ids survive a rebuild), `images import` (product imagery from the openly licensed source), `discussion import` (the decision cards on `/discuss` from `import/discussion.json`), `discussion inbox --for claude [--since ]` (what rian said to the next session on `/issues`; `ACCOUNTS.md` Notifications), `sources` (list, and the per-source kill switch), `locations --show/--hide` (site visibility), `indexnow --since | --hours N [--dry-run]` (after a collection, once `INDEXNOW_KEY` is set and the host is not gated), `audit`, `verify`, `verify-status`, `verify-clear` (`QUALITY.md`), `articles`, `subscribers` (Content, below). The generated reference at the end of this file is the authority for flags. Environment (`app/config.py`, read from `.app.env`): `APP_ENV` (production unless set), `DATABASE_URL`, `PUBLIC_BASE_URL` (the origin every absolute URL is built from; required in production), `INDEXNOW_KEY`, the feature switches `FEATURE_MY_AIRPORTS`, `FEATURE_FEATURED_HOME`, `FEATURE_RICH_CARDS`, `FEATURE_TEASERS`, `FEATURE_CLIENT_TODOS`, the social profiles `SOCIAL_INSTAGRAM_URL` and `SOCIAL_YOUTUBE_URL`, `BROWSER_URL` (the render sidecar; empty means no browser), `FETCH_SERVICE_KEY` (absent by design), `ACCOUNT_OWNER` and `SITE_ACCESS` (the account system, under Accounts below), and `MAIL_PROVIDER`, `MAIL_FROM`, `RESEND_API_KEY` (mail for invites and resets; `none` until a provider is staged). A `REPLACE_WITH_` placeholder reads as absent everywhere. Host-side scripts in `main/scripts/` (run with the workspace Python, from the workspace root): `items.py` (the running list), `plan-set.py` (task status on `/plan`), `docmap.py` (the generated doc blocks), `seed-todos.py` (the client to-do rows, applied inside the container), `review-checklist.py` (the thirty-page human check), `beauty-candidates.py` (the targeted list), `export_competition_winners.py` (the winners file from the competition network), `render-probe.py` (one rendered page through the sidecar). Each carries its usage in its docstring. ## The three tokens Rian grants each, one holder at a time (build plan §2): - **Deploy.** Sessions build and test locally and never deploy. Say "green and ready". - **Migration.** One head, serialized, schema-only, as above. - **Crawl.** Long runs announce a window in `.logs/runs/`; no deploy inside it. ## Deploy (rian) A deploy recreates the app container and **kills any running collection**. 1. Check nothing is running: `ls -lt .logs/runs/ | head` and `pgrep -af app.cli`. 2. If the deploy carries a migration, dump first: `docker exec dutyfreeprofessor-db pg_dump -U dfp -Fc dfp > backups/dfp-$(date +%F)-.dump` 3. Bump `main/app/version.py`, and turn the `## Unreleased` heading in `main/CHANGELOG.md` into that version with today's date. `docs-check.sh` fails if the two disagree, or if the NOW block in `brief.md` still names the old version. 4. `main/check.sh`, then `srv-gw deploy --project dutyfreeprofessor --build`. 5. Confirm: `curl -s https://dutyfreeprofessor.demoing.info/api/health` shows the new version; `srv-gw security-audit` after any change to compose or ports. ## Collecting Inside the container: `docker exec dutyfreeprofessor-app python -m app.cli collect [--source ] [--limit N] [--delay S]`. One process per host so each host's crawl delay applies independently. Every run re-reads robots.txt; a refusal ends the run (`main/docs/COLLECTORS.md`). Log long runs to `.logs/runs/`. The per-source kill switch is the `enabled` column on `sources` (`/api/sources`, the sources page); a collector can be stopped without a deploy, which is a legal control, not a convenience. ## Content (articles in, subscribers out) Adam's text arrives on `/todo` as Word, Markdown or plain-text uploads, stored under `uploads//` (mounted read-write at `/srv/uploads`). Inside the container: ```bash docker exec dutyfreeprofessor-app python -m app.cli articles import --todo --author rian docker exec dutyfreeprofessor-app python -m app.cli articles import --upload --kind airport_writeup --airport LHR docker exec dutyfreeprofessor-app python -m app.cli articles list --all # drafts too docker exec dutyfreeprofessor-app python -m app.cli articles publish [ ...] ``` A file that is not an upload goes into `import/editorial/` on the host (create the folder on first use; read-only in the container at `/srv/import/editorial/`) and is imported by path. Imports are drafts and idempotent on slug: fix the text, run the same command, nothing is republished or unpublished. Word images are counted and left out; put them under `public/` with versioned names and reference them from the text. `--airport` and `--category` give the keyed kinds one slug per airport or category, so a second hand-in replaces the first. The subscriber list is personal data and leaves the database only through the owner's shell, to a file only rian can read; never into `backups/` or `uploads/` (group-readable, served): ```bash docker exec dutyfreeprofessor-app python -m app.cli subscribers stats docker exec dutyfreeprofessor-app python -m app.cli subscribers export > ~/subscribers-$(date +%F).csv && chmod 600 ~/subscribers-*.csv docker exec dutyfreeprofessor-app python -m app.cli subscribers unsubscribe

It mirrors the dev server's shape: the same compose file plus `docker-compose.production.yml`, Caddy alone on 80 and 443, the app on the bridge port, Postgres on the internal network with no published port. The app gates itself (`SITE_ACCESS`); Caddy carries no gate. - **Reach it:** `ssh deploy@bwlive` (keys only, from the tailnet or the dev server; root is off). Break-glass if the tailnet is gone: DigitalOcean's recovery console after a root password reset. - **Deploy:** `deploy/production.sh` from this repository on the dev server. It dumps the production database first, rsyncs `main/`, `import/`, `public/`, `uploads/` and the compose files over Tailscale, builds there, recreates, and waits for `/api/health`. Add `--caddy` when `deploy/caddy/` changed. It never copies `.app.env` or `data/`. A deploy kills a running collection there too: check `.logs/runs/` first. - **First deploy only:** `deploy/production.sh --seed-db backups/dfp-nightly-.dump` restores the dev server's nightly dump into the empty production database. - **Roll back:** check out the previous commit and run `deploy/production.sh` again; a migration that rode along is reversed by restoring the pre-deploy dump it took (`backups/dfp--pre-deploy.dump` on the droplet). - **Restore from dump** (rehearse into a scratch database first, as on dev): `docker exec -i dutyfreeprofessor-db pg_restore -U dfp -d dfp --clean --if-exists --no-owner < backups/.dump` - **Backups:** the deploy user's crontab dumps nightly at 03:15 UTC into `backups/`, 14 days; the dev server pulls that directory into `backups/production/` at 04:15 local (`deploy/install-backup-cron.sh` installs both). DigitalOcean snapshots, if enabled, are the whole-box tool; the dumps are the everyday one. - **Secrets:** `.app.env` on the droplet (0600, deploy user). Machine secrets were generated there; the owner's values are filled in his own shell, never in chat. Caddy's Cloudflare DNS token lives in `/srv/caddy/cloudflare.env`, scoped to the one zone. Rotate by editing the file and recreating the container. - **Certificates:** a Cloudflare Origin CA certificate (15 years) in `/srv/caddy/origin/` on the droplet, trusted only by Cloudflare's edge, so the zone must stay proxied and Full (strict). Renew by creating a new one in the dashboard and pasting it over the two files, then `docker compose up -d` in `/srv/caddy`. The DNS-challenge module stays configured for any un-proxied host (`deploy/caddy/`). - **Egress:** `deploy/egress-test.py` re-runs the retailer check from any machine; compare against a same-day run from the dev server before trusting a new address. - **The sidecar fence:** `deploy/sidecar-firewall.sh`, owner-applied, keeps the browser sidecar off private ranges and the cloud metadata service. ## Backups and restore - Nightly `pg_dump` from rian's crontab at 03:15 into `backups/dfp-nightly-.dump`, kept for 14 days; failures append to `.logs/runs/backup.log`. Manual dumps before risky work follow the same shape with a reason in the name. - Restore (rehearse on `dfp-devdb` first): `docker exec -i dutyfreeprofessor-db pg_restore -U dfp -d dfp --clean --if-exists < backups/.dump` - `data/postgres/` is the live cluster and is not the backup. ## Staging refresh Adam comments on staging, so a refresh from production must keep every table people write on the site (`CLIENT_WRITTEN_TABLES` in `app/services/discussion.py`: the decision cards and their comments, the feature ranking, the quote selections and requests, the to-dos and their uploads, rian's running-list states; the list grows with the schema and the refresh reads it, never a copy). One host command, from the workspace root: ``` python3 main/scripts/staging-refresh.py --from backups/production/.dump --check python3 main/scripts/staging-refresh.py --from backups/production/.dump ``` `--check` exports every client-written row to `backups/refresh/-client-rows.json`, prints the counts and the commands the real run would issue, and restores nothing. The real run exports again, drops and recreates the `public` schema in the database container, restores the dump, runs `alembic upgrade head` in the app container (production may be behind staging), `backfill accounts` and `backfill levels`, then puts the exported rows back through `app.cli staging-refresh apply` and revokes every session (production's session rows are not staging's; sign in again). The report says, per table, what was restored, what was already there, what was updated or kept on a natural-key conflict (the newer row wins, a tie keeps production's) and what was renumbered (a comment whose id production has since used comes back under a fresh id; the deep link to the old id then lands on production's comment). Who-columns are remapped by username, so account ids need not agree between hosts; an author whose account does not exist on the restored side keeps the typed name with an empty link, and `backfill authors --map` relinks once the account exists. A second run of `apply` on the same file changes nothing. The export file is kept: whatever fails after it, the rows are on disk, and `app.cli staging-refresh apply --from - < ` inside the container puts them back. The seeded to-do text is production's after a refresh; re-run `seed-todos.py` on staging if it should differ. The app container is not stopped; a request during the restore fails once. Rehearse on `dfp-devdb` first: `--db dfp_r --db-container dfp-devdb --app-exec "../.venv-dev/bin/python -m app.cli" --alembic-exec "../.venv-dev/bin/alembic"` with `DATABASE_URL` pointed at `dfp_r`. Rehearsed 11 Sep with Adam's three comments of that day as the rows that had to survive (`tests/test_staging_refresh.py` pins the policy on SQLite). ## Secrets `.app.env` (mode 660) holds the database password and any service keys; the compose file reads it for both containers. Never print it, never commit it, never paste a value into chat. ### Accounts The site's own login (`ACCOUNTS.md` is the mechanism; this is the procedure). Two lines in `.app.env`, staged as placeholders in `.app.env.example` at the workspace root: ``` ACCOUNT_OWNER=REPLACE_WITH_USERNAME # the super admin; the owner is code, not a row SITE_ACCESS=members # sign in to see anything; `public` is the go-live flip ``` Set them in your own shell; delete `OWNER_PASSWORD` and `SESSION_SECRET` if present (ignored either way). Tighten the file so only you and the gateway read it: `setfacl -b .app.env && chmod 600 .app.env && setfacl -m u:srv-gateway:r .app.env` (a bare `chmod 600` sets the ACL mask to nothing and `srv-gw deploy` fails, because the gateway's compose reads `env_file` as `srv-gateway`); check with `sudo -u srv-gateway test -r .app.env && echo readable` (reads nothing); `srv-gw fix-permissions` widens it back to 660 plus the group ACL, so re-run the `setfacl` line after any permissions repair; `grep -c REPLACE_WITH_ .app.env` prints 0. Then recreate the container. With the owner unset the startup log says CRITICAL, nobody is super admin and the site stays up; `python -m app.cli accounts owner-check` says the same. **Seeding a host**, inside the container after the deploy that carries migration #4, in order: ``` python -m app.cli backfill accounts python -m app.cli backfill levels python -m app.cli accounts create --username adam --email --display-name Adam --level admin python -m app.cli accounts create --username mark --email --display-name Mark --level admin python -m app.cli accounts set-password --username rian # prompted twice, never argv python -m app.cli accounts invite-link --username adam # printed once; send it yourself python -m app.cli accounts invite-link --username mark python -m app.cli backfill authors --map Adam=adam --map Mark=mark --map rian=rian ``` A welcome link is `https:///welcome#`: the token is the fragment, so it never reaches a request line. The container's stdout is an access log of every request line, so nothing secret may ever sit in a URL path or query; the CLI prints a link once to your terminal and to nothing else. Links work for 48 hours and once. `accounts reset-link` is the same for a forgotten password until a mail provider exists (`MAIL_PROVIDER=resend` with `RESEND_API_KEY` and `MAIL_FROM` in an app-only env file, never the shared one); then `/forgot` on the site and "Send reset link" in the People panel work too. Other commands: `accounts list | disable | enable | unlock`, `sessions revoke --username | --all` (the break-glass: everyone out at once), `sessions prune`, `audit-log prune`, `accounts bench` (the argon2 cost on this host). The generated reference at the end of this file has the flags. **Rollout on the dev host** (the staging order, in full, in the accounts plan §7): dump first because a migration rides; the two lines above; the tightening; bump the version and deploy; seed as above and `awards --rebuild` if it is still pending; the curl list from the host against `http://172.17.0.1:` (every POST with `-H 'Origin: https://'`); the browser round trip; `srv-gw security-audit`; then, owner only, `srv-gw id-gate --site --mode public`, after which the app's login is the only barrier (rollback: `srv-gw id-gate --site `); the curls again through the public host; `srv-gw security-audit` again. Production repeats the seeding with its own passwords and links minted on its own `PUBLIC_BASE_URL`; the curl list runs through the domain credential before it comes off. **Transfer of ownership:** set `ACCOUNT_OWNER` to the new owner's username, create that account (`accounts create`, `set-password`), recreate the container; the previous owner's row is an ordinary account from then on, and nothing in the codebase points at this server. **One worker.** The per-address login throttle and the argon2 semaphore live in the process: one uvicorn worker is a launch assumption, and a `login_attempts` table comes before a second. **Members-only and the flip.** `SITE_ACCESS=members` answers every anonymous page with a 302 to `/login`, serves `Disallow: /` and no sitemap, and stamps `X-Robots-Tag: noindex, nofollow` on every response. The flip to `public` is the go-live checklist's step (with the IndexNow key and the uptime checks), one env line and a container recreate; it is never set earlier. ### Mail The provider is Resend behind three lines, `MAIL_PROVIDER=resend`, `MAIL_FROM=` and `RESEND_API_KEY`, and they belong in an **app-only env file**, never `.app.env`, which the database container reads too (`docker-compose.yml` gives both containers the same `env_file`; the split is Stream W's W3 and its compose change gets a security review and `srv-gw security-audit` first). Until those lines exist every mail path is inert: invites and resets go by CLI link, the People panel says so, and `notify digest` reports "no mail provider" and stamps nothing. When they do: every send counts against a daily cap in `email_sends` (6 auth mails per account: welcome, reset, access notice; 25 invites per host; 40 notification mails per account), a spent cap refuses before the provider is called (`MAIL_CAP` in the People panel), and the notification digest goes out from host cron on the machine that runs the app: ``` */30 * * * * docker exec dutyfreeprofessor-app python -m app.cli notify digest >> /srv/apps/dutyfreeprofessor/.logs/runs/notify-digest.log 2>&1 ``` One mail per person per run for the rows not yet delivered (a row already read in the app is stamped delivered and not mailed; a person who turned mail off under Account, or has no email, is skipped and their rows wait); `notify digest --check` prints what would go out and writes nothing. Nothing about a message is logged beyond the provider's status. ## What lives where Workspace root: docs, `.logs/`, compose, `import/` (read-only into the container, so the `/plan` page and the awards and discussion imports update without a deploy), `public/` (explainer pages served at `/.html`), `data/`, `backups/`. Code: `main/`.
