--- This migration slot is preserved for historical DB compatibility.
--- The original content added a `password_hash` column to a legacy `users`
--- table used by the old Auth.js Credentials provider. That table no longer
--- exists — auth moved to Neon Auth (Better Auth), which manages its own
--- `neon_auth.user` schema. See CLAUDE.md "Authentication & Authorization".
+-- Adds a `password_hash` column to `users` so the Auth.js Credentials
+-- provider can verify email + password against the database.

--- Production DBs that ran the original migration already have this filename
--- recorded in `_migrations` and will skip it. Fresh DBs would otherwise
--- fail on `ALTER TABLE users`; this no-op keeps the apply path clean while
--- preserving the migration numbering (0003_*.sql onward is unaffected).
+-- Idempotent: uses `ADD COLUMN IF NOT EXISTS`. The column is nullable
+-- because OAuth-only users (Google) never set a password.
 --
--- Do not reintroduce an `ALTER TABLE users` here — the table does not exist
--- and Neon Auth owns user identity.
+-- The Credentials provider's `authorize` function is documented in
+-- `src/lib/auth.ts` — it queries this column and runs `verifyPassword`
+-- (see `src/lib/passwords.ts`) before returning the user.
