The "Run migrations" job (and thus the whole deploy) was failing on every push after the first successful bootstrap with:
✗ 0001_init.sql failed: relation "admin_users" already exists
Root causes:
- 0001_init.sql used plain CREATE TABLE/INDEX/TRIGGER despite the header comment claiming "CREATE TABLE IF NOT EXISTS".
- The _migrations tracking row for 0001_init.sql was never recorded on the prod DATABASE_URL (tracking logic landed after initial apply, or apply happened outside the runner).
Fix (3 layers of defense):
* db/migrations/0001_init.sql: every CREATE TABLE now uses IF NOT EXISTS (63 tables), CREATE INDEX uses IF NOT EXISTS (49), all CREATE TRIGGER wrapped in safe DO $$ IF NOT EXISTS (pg_trigger join check) THEN ... END IF; $$, removed the file's own BEGIN/COMMIT so the runner's transaction is authoritative. RLS drop+create and CREATE OR REPLACE FUNCTION were already safe.
* scripts/migrate.js: added ensureTracked() right after loading the applied set. For 0001/0002, if the core objects (admin_users table, password_hash column) already exist in information_schema but the tracking row is absent, INSERT the filename (ON CONFLICT DO NOTHING) and log "repaired tracking". Then the normal skip path handles it.
* .gitea/workflows/deploy.yml: added an inline node -e pre-repair (same admin_users existence check → force _migrations row) immediately before `npm run migrate:one`. This protects even on an older checkout of the runner. The neon_auth preflight and post-apply "admin_users must exist" hard gate are untouched.
* Minor: cleaned 0002_admin_password.sql tx wrapper for consistency; updated MEMORY.md with the incident + resolution.
Result: deploys (and any server-side `node scripts/migrate.js` recovery runs) on an already-initialized prod DB will repair/skip 0001 cleanly, pass the verification query, and continue to build/deploy. The scp of scripts/ + db/migrations/ in the Deploy step now carries the fixed versions.
See the plan note in deploy.yml and MEMORY.md for background.
