//
// Pre-build sanity check: probes every PocketBase filter used by the driver
// app against the live server and reports any reference to an unknown
// field. Catches the exact "added a clause to a filter, forgot to add the
// field to PB" class of bug that produced the July-2026 4×400 incident.
//
// Usage:
//   npm run check-pb-schema
//
// Env (optional — defaults match this project's dev PB + e2e creds):
//   NEXT_PUBLIC_POCKETBASE_URL=https://your-pb.example.com
//   PB_USER_EMAIL=...
//   PB_USER_PASSWORD=...
//
// Exit codes:
//   0  all filters and identifiers parse against the live schema
//   1  one or more filters reference unknown fields
//   2  couldn't authenticate against PB (fix env / network first)
