Subject: [PATCH] Implement tasks 60, 61, 62: backups, rate limiting,
 structured logging
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Task 60 — Postgres backups:
- deploy/backups/: backup.sh (pg_dump -Fc nightly), retain.sh (14/8/6 tiers),
  restore.sh, entrypoint.sh, crontab
- famapp-backup Alpine service + backups volume added to deploy/compose.yaml
- Restore procedure in deploy/backups/README.md

Task 61 — Rate limiting on share links:
- src/lib/rate-limit.ts: Edge-compatible sliding-window counter (50/min, LRU eviction)
  with consume(), isRateLimited(), recordFailure() exports
- middleware.ts: enforces 429 with Retry-After: 60 for /s/[token] (IP + token prefix)
- /s/[token]/page.tsx: tracks only failed resolveShareToken calls via recordFailure()

Task 62 — Structured logging:
- pino + pino-pretty installed; serverExternalPackages added to next.config.ts
- src/lib/logger.ts: JSON in production, pretty in dev, level from LOG_LEVEL env
- middleware.ts: structured JSON request log (method, path, status, ms, authenticated)
- _core/push.ts, notify.ts, reminders.ts: console.error/log → logger.error/info

 - **41 — Reminders engine**. Added `fired_at` and `created_by` columns to `reminders` table (migration `0013_push_notify_reminders.sql`); default channel changed to `'auto'`. Created `_core/reminders.ts` with `scheduleReminder` (upsert by entity), `cancelReminder`, `listReminders`, and `tickReminders` (30 s tick, `pg_try_advisory_xact_lock` guard). `startReminderWorker()` started via `src/instrumentation.ts` on the Node.js runtime. Notes actions updated to use `scheduleReminder`/`cancelReminder` instead of raw SQL. Calendar `createEvent` accepts optional `remindMinutesBefore` and schedules a reminder; `deleteEvent` calls `cancelReminder`. Calendar-shell event dialog shows "Remind me 30 min before" checkbox (new events only, checked by default). Reminder worker confirmed starting on server boot (logged in dev server output). `pnpm typecheck`, `pnpm lint`, `pnpm build` pass.
 
+- **60 — Postgres backups**. `famapp-backup` Alpine service added to `deploy/compose.yaml`; scripts in `deploy/backups/`: `backup.sh` (`pg_dump -Fc` for famapp-db + authentik-db nightly at 02:00), `retain.sh` (14 daily / 8 weekly / 6 monthly), `restore.sh` (restore from any dump file), `entrypoint.sh` (installs postgresql-client, sets up crontab, starts crond). Backup files stored in `backups` named Docker volume. Restore procedure in `deploy/backups/README.md`. `pnpm typecheck`, `pnpm lint`, `pnpm build` pass.
+- **61 — Rate limiting on share links**. `src/lib/rate-limit.ts`: pure-JS Edge-compatible sliding-window counter (50 req/min, 1-min window, 10k-key LRU eviction) with `consume()`, `isRateLimited()`, and `recordFailure()` exports. `src/middleware.ts` calls `consume(ip:prefix)` for every `/s/[token]` request and returns 429 with `Retry-After: 60` when the bucket is exceeded. `src/app/s/[token]/page.tsx` additionally tracks only failed `resolveShareToken` lookups via `recordFailure()` in the Node.js runtime (separate module instance from middleware; Redis would unify them for multi-replica deployments). `pnpm typecheck`, `pnpm lint`, `pnpm build` pass.
+- **62 — Structured logging**. Installed `pino` + `pino-pretty` (dev). `src/lib/logger.ts`: pino instance — JSON in production (`stdout`), pretty-printed in dev; level from `LOG_LEVEL` env (default `info`); `pid`/`hostname` stripped, ISO timestamps. `src/middleware.ts` logs every request as structured JSON via `console.log` (Edge-compatible; pino not available in Edge runtime) with `method`, `path`, `status`, `ms`, `authenticated`. All `console.error`/`console.log` calls in `_core/push.ts`, `_core/notify.ts`, `_core/reminders.ts` replaced with `logger.error`/`logger.info`; sensitive fields (endpoint URLs, keys) are never logged as named fields. `next.config.ts` adds `serverExternalPackages: ["pino","pino-pretty"]` so webpack does not bundle them. `pnpm typecheck`, `pnpm lint`, `pnpm build` pass.

+# Backups
+
+The `famapp-backup` service performs nightly compressed `pg_dump` of both
+`famapp-db` and `authentik-db` at **02:00 server time**.
+
+## Storage layout
+
+```
+/backups/           (named Docker volume: famapp_backups)
+  famapp/
+    daily/          ← last 14 days
+    weekly/         ← last 8 Sundays
+    monthly/        ← last 6 first-of-month dumps
+  authentik/
+    daily/
+    weekly/
+    monthly/
+```
+
+Dump files are named `YYYY-MM-DD.dump` in custom (`-Fc`) format (internal
+compression, ~3–5× smaller than plain SQL).
+
+## Retention
+
+| Tier    | Kept | Trigger               |
+| ------- | ---- | --------------------- |
+| daily   | 14   | every night           |
+| weekly  | 8    | Sunday night          |
+| monthly | 6    | 1st of the month      |
+
+Retention is enforced by `retain.sh` at the end of each `backup.sh` run.
+
+## Restore procedure
+
+### 1. Identify the dump
+
+```sh
+# List available dumps
+docker exec famapp-backup-1 ls /backups/famapp/daily/
+```
+
+### 2a. Restore inside the backup container (recommended)
+
+```sh
+docker exec famapp-backup-1 /scripts/restore.sh \
+  /backups/famapp/daily/2024-06-01.dump \
+  postgres://famapp:SECRET@famapp-db:5432/famapp
+```
+
+Replace `SECRET` with the value of `FAMAPP_DB_PASSWORD` in your `.env` file.
+For authentik:
+
+```sh
+docker exec famapp-backup-1 /scripts/restore.sh \
+  /backups/authentik/daily/2024-06-01.dump \
+  postgres://authentik:SECRET@authentik-db:5432/authentik
+```
+
+### 2b. Restore to a separate database (safe — non-destructive)
+
+Create a fresh target database first, then restore into it:
+
+```sh
+# Create the target DB
+docker exec famapp-db-1 createdb \
+  -U "$FAMAPP_DB_USER" famapp_restore
+
+# Restore
+docker exec famapp-backup-1 /scripts/restore.sh \
+  /backups/famapp/daily/2024-06-01.dump \
+  postgres://famapp:SECRET@famapp-db:5432/famapp_restore
+```
+
+### 2c. Restore on a fresh host (disaster recovery)
+
+```sh
+# Copy the dump file out of the volume
+docker cp famapp-backup-1:/backups/famapp/daily/2024-06-01.dump ./
+
+# Spin up a temporary Postgres container and restore
+docker run --rm \
+  -e PGPASSWORD=SECRET \
+  -v "$(pwd)/2024-06-01.dump:/dump.dump:ro" \
+  postgres:16-alpine \
+  pg_restore -h <new-db-host> -U famapp -d famapp \
+    --no-owner --no-acl /dump.dump
+```
+
+## Off-site replication
+
+The backups live in the `famapp_backups` Docker named volume. To copy them
+to another host, rsync the volume's data directory periodically (e.g. from a
+host cron job):
+
+```sh
+# On the Docker host, add to /etc/cron.d/famapp-rsync:
+30 3 * * * root rsync -a --delete \
+  /var/lib/docker/volumes/famapp_backups/_data/ \
+  user@offsite-server:/opt/famapp-backups/
+```
+
+Encryption at rest is handled at the disk/filesystem layer (e.g. LUKS).
