Convoy: single-sql-client (P1 quality, launch sequence step 8)
Addresses: AGENTS.md Gotcha #1, .convoys/ship-readiness.md P1 #8
## Decisions
- D1: Caller inventory = 2 files (1 source + 1 test), not "~3 based on graph".
Only pages/api/auth-utils.js imports `db`; test/api/auth-utils.test.js mocks
it purely to satisfy the import graph (the 5 tests exercise
generateToken/verifyToken, not isAdmin/getUserById).
- D2: Migrate both call sites (isAdmin, getUserById) to @vercel/postgres
tagged-template SQL. Queries are SELECT-only, single-table,
single-numeric-parameter — byte-equivalent translation; same result shape
({rows, rowCount}); no transaction or pool semantics differ.
- D3: KEEP @neondatabase/serverless as a dep. 11 scripts/* files still use
`neon()` directly (setup-neon-db.js, migrations/, reset-db.js, 8 historical
add-*/fix-*/seed-* jobs). They are out of scope per the no-go-zones rule
and the convoy spec; purging the dep entirely would be its own convoy
(queued as `purge-neondatabase-serverless-fully`, blocked on migration-tool).
- D4: sql.unsafe audit — NOT a real injection vector with current callers
(userId comes from a verified JWT, is a numeric SERIAL id). Security
finding: NO. Pure refactor + foot-gun removal that prevents the FUTURE
caller that would have been the incident.
- D5: Test mock cleanup — drop the now-unneeded `vi.mock('../../lib/database.js')`
call + unused `vi` import. Test count + assertions unchanged (5/5).
## Per-file changes
- pages/api/auth-utils.js: swap `import { db } from '../../lib/database.js'`
for `import { sql } from '@vercel/postgres'`; rewrite isAdmin's
`db.query(SELECT … WHERE id = $1, [userId])` and getUserById's same shape
to `sql\`SELECT … WHERE id = ${userId}\``. Same try/catch, same
result.rows[0] access, same error returns.
- test/api/auth-utils.test.js: drop vi.mock for lib/database.js + the unused
`vi` import. 5/5 tests still pass.
- lib/database.js: DELETED (47 lines removed; manual-interpolation + sql.unsafe
wrapper is gone).
- .convoys/single-sql-client.md: NEW (the convoy file documenting all
decisions + caller inventory + verification + risks + follow-ups).
## Verification
- npm run lint → 128 problems (baseline preserved, no regression)
- npm run test:run → 21/21 pass (vitest)
- Grep "lib/database" --type js -l → 0 hits anywhere
- Grep "@neondatabase/serverless" --type js -l → still matches the 11
scripts/* sites (expected; out of scope per D3)
- node --check pages/api/auth-utils.js → exit 0
## Scope note
This convoy collapses the lib/database.js abstraction onto the canonical
@vercel/postgres surface for pages/api/**. It does NOT eliminate
@neondatabase/serverless from the dependency tree — that would require
migrating the scripts/* helpers, which is out of scope here (no-go-zones
rule + convoy spec). Queued as a follow-up.
## Live smoke
Deferred. The two migrated functions (isAdmin, getUserById) are only
reachable via pages/api/admin/index.js which requires an admin Bearer
token and a populated users table in prod Neon. Byte-equivalent SQL +
identical result shape gives high confidence; rollback is a single-commit
revert if a post-merge admin action 500s.

- New `lib/auth-secret.js` is the single source of truth for `JWT_SECRET`
and the canonical `JWT_TOKEN_TTL = '24h'`. Module throws at import time
if `process.env.JWT_SECRET` is unset — no silent fallback to the literal
`'your-secret-key-change-in-production'`.
- 7 callers refactored to import from the helper:
lib/permission-middleware.js
pages/api/auth-utils.js (also drops unused `'7d'` → JWT_TOKEN_TTL)
pages/api/auth/login.js (also routes via auth-utils.generateToken)
pages/api/auth/register.js (same)
pages/api/auth/verify.js (Brief 2 still owns the no-token admin branch)
pages/api/favorites.js
pages/api/users/search.js
- `process.env.JWT_SECRET` now appears exactly once in the JS source
(lib/auth-secret.js). `your-secret-key-change-in-production` is gone.
- TTL drift reconciled: auth-utils used `'7d'`, login/register used
inline `'24h'`. Both now route through imported `JWT_TOKEN_TTL` (24h).
Pre-deploy reminder: Vercel must have `JWT_SECRET` set before merge or
serverless functions refuse to boot. Existing tokens (signed against the
fallback literal) will be invalidated — users will need to log in again.
Resolves AGENTS.md gotcha #3. Brief 2/3/4/5 still pending in convoy.
