+ * reset.ts — Drop all application tables, re-run migrations, and re-seed.
  *
  * Intended for local development only. Never run against production.
  *
  * Usage:
  *   DATABASE_URL=postgres://... npx tsx packages/db/src/reset.ts
+ *
+ * GRO-2139: the entire drop→migrate→seed chain runs inside a single
+ * Postgres advisory lock (SEED_ADVISORY_LOCK_KEY) so a concurrent
+ * `seed.ts` (e.g. the dev `seed-test-data-*` Job being recreated at
+ * the top of the hour) cannot interleave between `reset.ts` (DROP)
+ * and `seed.ts` (TRUNCATE+insert) and collide on `invoices_pkey`.
+ *
+ * Why this matters: `seed.ts` derives every primary key from a single
+ * shared Mulberry32 PRNG seeded with 42 (see `createPrng(42)` and
+ * `uuid()` in seed.ts). Two concurrent same-profile seeders therefore
+ * emit *identical* ids for the same logical row, and any moment
+ * between a concurrent `seed.ts` TRUNCATE and INSERT is exactly the
+ * window in which the second seeder's INSERT can hit a pkey already
+ * taken by the first. Pre-GRO-2123 this raced unconditionally;
+ * GRO-2123 added the advisory lock around `runSeedBody` but left
+ * `reset.ts` and `drizzle-kit migrate` outside the lock. This script
+ * now wraps the *whole* chain in the same lock: `withSeedAdvisoryLock`
+ * pins the lock to one reserved session and the DROP → migrate → seed
+ * work runs on the rest of the pool, so the lock guarantees mutual
+ * exclusion against any concurrent seeder for the entire chain.
+ *
+ * See: groombook/infra `apps/base/reset-cronjob.yaml` (CronJob) and
+ * `apps/base/seed-job.yaml` (one-shot Job) — both invoke the same
+ * `seed.ts` code path on the same database in `groombook-dev`.

+
+/**
+ * GRO-2311 / GRO-2313: give the UAT portal customer (`uat-customer@groombook.dev`)
+ * a deterministic spread of appointments so the customer-portal StatusBadge
+ * palette can be LIVE-observed (not just code-verified against the bundle).
+ *
+ * `appointment_status` enum is (`scheduled, confirmed, in_progress, completed,
+ * cancelled, no_show`) — the portal's <StatusBadge> renders `appointment.status`
+ * verbatim. `pending` and `waitlisted` are NOT valid appointment statuses, so
+ * GRO-2319 derives them in the portal: `pending` from an upcoming appointment's
+ * `confirmationStatus` (the `scheduled` row below carries `pending`), and
+ * `waitlisted` from an ACTIVE `waitlist_entries` row (seeded at the end of this
+ * function) which `GET /api/portal/appointments` surfaces as a synthetic card.
+ * The `no_show`→`no-show` badge-key fix is the web side of GRO-2319.
+ *
+ *   - confirmed  → future startTime → renders as an Upcoming card (Confirmed badge)
+ *   - scheduled  → future startTime → renders as an Upcoming card (Scheduled badge)
+ *   - cancelled  → past startTime   → Past tab (isUpcoming excludes cancelled)
+ *   - no_show    → past startTime   → Past tab (raw `no_show` label until GRO-2319)
+ *
+ * The existing GRO-2100 `completed` appointment (a0000001-…-0001) is left
+ * untouched (AC #4), so Completed is also covered.
+ *
+ * Idempotent: each appointment uses a fixed UUID and is upserted with
+ * onConflictDoNothing, so the hourly reset-demo-data CronJob (which TRUNCATEs
+ * then re-seeds) and non-truncating dev re-seeds never dup-key
+ * (see GRO-2033 for the dup-key class).
