# Production DB Schema Migration Reliability Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:systematic-debugging (completed root cause), superpowers:writing-plans (this), superpowers:test-driven-development where code changes have tests, superpowers:verification-before-completion, and superpowers:executing-plans or subagent-driven-development to implement task-by-task. Steps use checkbox syntax.
**Goal:** Ensure that every production deploy (push to main) results in the full schema from `db/migrations/0001_init.sql` (including the `admin_users` and `admin_user_brands` tables required by `getAdminUser()`) being present in the `DATABASE_URL` that the running app connects to via its pool / drizzle client. Eliminate "relation does not exist" errors and the resulting Access Denied screen for properly provisioned Neon Auth users.
**Architecture:**
- Make the CI "Run migrations" step a hard gate (fatal on failure, plus explicit post-migrate verification that critical tables exist).
- Ship the minimal migration runner + SQL files as part of the deploy artifact so the target server has a recovery path.
- Add a lightweight post-deploy / startup verification in the app or deploy script (fail fast with clear message instead of silent 500s on first admin request).
- Keep the "migrate from full source locally" path working for initial prod DB bootstrap and emergencies.
- Do not change the core migration logic or 0001_init.sql in this plan (that would be a separate architectural change if the double-BEGIN wrapping proves fragile).
**Tech Stack:** Gitea Actions (YAML), Node 22 + pg + drizzle on target, Next.js standalone output, pm2 on Ubuntu server, Neon Postgres (with neon_auth schema).
**Root Cause (from systematic-debugging Phase 1):** The prod runtime DB lacked the `admin_users` table because (1) the migration step in `.gitea/workflows/deploy.yml` used `|| echo` making any failure (connection, SQL error in the huge 0001 file, FK to neon_auth.user, tx nesting from the file's BEGIN + script's BEGIN) non-fatal, (2) only `.next/`, `public/`, `package.json` (and optional next.config) are scp'd — `scripts/migrate.js` and `db/migrations/` are never on the server, (3) no verification after "migrate" or at app startup that the tables the admin permission layer depends on actually exist, (4) the `.env.production` written from the same secret as the CI migrate step was used, but the apply didn't happen or was skipped due to _migrations state or partial rollback.
**Evidence Gathered:**
- deploy.yml: Run migrations step, limited scp, .env.production printf, pm2 "npm start".
- scripts/migrate.js: dotenv .env.local + env override, _migrations tracking, per-file client.query(sql) inside script tx, re-throw on error.
- db/migrations/0001_init.sql: explicit CREATE TABLE admin_users (with FK to neon_auth.user), admin_user_brands, brands; file starts with BEGIN;.
- db/client.ts + src/lib/admin-permissions.ts: withPlatformAdmin → drizzle select on adminUsers from schema (the exact query that 42P01s).
- next.config.ts: output: 'standalone' (explains pm2 warning).
- Runtime logs: the repeated "Database query failed" + "relation does not exist", app starts fine.
- Git history: recent deploy "fixes" focused on SSH/env writing, not migration reliability.
**Files to touch (decomposition by responsibility):**
- `.gitea/workflows/deploy.yml` (CI pipeline gates + artifact contents)
- `scripts/migrate.js` (minor hardening if needed for verification hook)
- `src/app/api/health/route.ts` or similar (new, for startup/schema check — or add to existing)
- `CLAUDE.md` + `PRODUCTION_DEPLOYMENT_CHECKLIST.md` (docs)
- Possibly a small `scripts/verify-prod-schema.js` helper
---
### Task 1: Make CI migration step a hard failure + add explicit verification for admin_users
**Files:**
- Modify: `.gitea/workflows/deploy.yml:23-27` (the Run migrations step and surrounding)
- [ ] **Step 1.1:** Replace the non-fatal migration line with a strict block that fails the job if migrate fails or the critical table is missing after.
```yaml
- name: Run migrations
env:
DATABASE_URL: ${{ secrets.DATABASE_URL }}
run: |
set -e
echo "=== Running migrations against prod DB ==="
npm run migrate:one
echo "=== Verifying critical schema (admin_users) ==="
node -e '
const {Client} = require("pg");
const c = new Client({connectionString: process.env.DATABASE_URL});
c.connect().then(() => c.query("SELECT 1 FROM admin_users LIMIT 1")).then(() => {
console.log("✓ admin_users table exists");
return c.end();
}).then(() => process.exit(0)).catch(e => {
console.error("✗ admin_users missing or inaccessible:", e.message);
process.exit(1);
});
'
```
- [ ] **Step 1.2:** Run a local simulation or note that the Gitea runner will now fail the whole deploy if the secret DB is missing the table (good — forces the bootstrap to happen before code that depends on it ships).
- [ ] **Step 1.3:** Commit the yml change with message referencing the root cause (missing table in prod due to masked migration).
### Task 2: Ship migration capability in the deploy artifact so server has a recovery path
**Files:**
- Modify: `.gitea/workflows/deploy.yml` in the "Deploy" step (the scp and ssh sections)
- [ ] **Step 2.1:** Add scp for the migration assets (after the existing public/.next scp):
```bash
echo "Copying migration runner and SQL..."
scp -o ConnectTimeout=15 -o StrictHostKeyChecking=no -r scripts/migrate.js tyler@...:$APP_DIR/scripts/ || true
scp -o ConnectTimeout=15 -o StrictHostKeyChecking=no -r db/migrations tyler@...:$APP_DIR/db/ || true
```
- [ ] **Step 2.2:** Update the server ssh install/restart line to also ensure the scripts dir has the right perms if needed, but mainly document that now `node scripts/migrate.js` will work on the server with the .env.production.
- [ ] **Step 2.3:** In the same Deploy step, after writing .env.production and before or after the pm2 restart, optionally run the migrate on the server as a belt-and-suspenders (using the just-written .env):
```bash
ssh ... "cd $APP_DIR && source .env.production 2>/dev/null || export \$(grep DATABASE_URL .env.production); node scripts/migrate.js || echo 'migrate on server completed or not needed'"
```
(Keep it non-fatal on server for now; the CI gate is the hard one.)
- [ ] **Step 2.4:** Test the scp paths in a dry-run or note the change.
### Task 3: Add a minimal runtime / startup guard (fail fast with clear message)
**Files:**
- Create: `src/app/api/health/db-schema/route.ts` (or add to an existing health if present)
- Or simpler: in the admin layout or a top level, but a dedicated health is better for PM2/docker.
- [ ] **Step 3.1:** Create a tiny health endpoint that does the same check the CI verification does (SELECT 1 FROM admin_users) using the existing pool or withDb, returns 200 or 503 with message "Schema not applied - run migrations".
- [ ] **Step 3.2:** Wire it so the deploy can curl it after restart as a final gate (in the workflow ssh step).
- [ ] **Step 3.3:** (Optional but recommended per defense-in-depth) Call a similar check early in getAdminUser or the admin layout and log a very loud message + return a better error than generic "does not have admin access" when the table is literally missing.
### Task 4: Update documentation and bootstrap instructions (so humans know the right sequence)
**Files:**
- Modify: `CLAUDE.md` (the Commands and Important File Locations + Gotchas sections)
- Modify or create: `PRODUCTION_DEPLOYMENT_CHECKLIST.md` or a new `docs/PROD_BOOTSTRAP.md`
- [ ] **Step 4.1:** In CLAUDE.md under "Commands" and "Adding a New Brand" / auth section, add a "First production deploy / new prod DB bootstrap" subsection:
1. Ensure the Neon project has neon_auth enabled and the DATABASE_URL secret in Gitea points to it.
2. (Before first code push that depends on admin) Locally or in a throwaway runner: `DATABASE_URL=prod... node scripts/migrate.js`
3. Then `DATABASE_URL=prod... npx tsx scripts/provision-admin.ts you@real.com platform_admin` (after signing in on the prod URL).
4. Push; the CI gate + shipped runner will keep it healthy on future deploys.
5. If you ever see "relation admin_users does not exist" in prod logs, the DB the app is talking to is not the one that had migrate run.
- [ ] **Step 4.2:** Add a note about the `|| echo` anti-pattern that was removed and why the new verification step exists.
- [ ] **Step 4.3:** Mention the standalone vs npm start issue (already in logs) and that the start command on server should eventually be updated to `node .next/standalone/server.js -p 3100` (can be a follow-up task).
### Task 5: Verification before claiming success (use the dedicated skill)
**Files:** (none new, just process)
- [ ] **Step 5.1:** Before merging the plan changes, use `superpowers:verification-before-completion` checklist: the change makes a fresh DB get the table, an "already applied" DB is a no-op, a deploy with missing table now fails the job early with clear output, a manual server migrate works because the files are there, the runtime health returns 200 when table present.
- [ ] **Step 5.2:** After the PR is on a branch, trigger a deploy to a staging or the real prod (with a test DB first if possible), capture the CI log showing the new verification passing, and the app logs showing no more "Database query failed" on /admin.
- [ ] **Step 5.3:** Run the provision script as the final user-visible test; confirm the Access Denied with email message is gone and the platform_admin can see the UI.
- [ ] **Step 5.4:** Document the before/after in the plan or a memory file.
### Task 6: (Stretch / follow-up) Improve the migrate script's resilience for huge init files (if the double tx ever bites again)
**Files:**
- Modify: `scripts/migrate.js`
- [ ] Only if during verification the 0001 apply is flaky: change the per-file execution to not wrap the file's own BEGIN/COMMIT, or use a separate connection, or exec `psql -f` (but keep node/pg for consistency). Add a comment explaining the previous fragility.
**Rollback / emergency:** If a deploy breaks because of this, the server now has the scripts + db/migrations copied, so SSH + `source .env.production; node scripts/migrate.js` is the recovery (exactly what the user was trying to do manually).
**Success criteria:**
- A brand new prod DB + push to main results in a green deploy + working /admin after provision.
- The error "relation \"admin_users\" does not exist" no longer appears in prod pm2 logs for normal admin flows.
- The pipeline fails loudly (with the table name in the error) instead of shipping a broken app that only shows "Access Denied".
