Parallelization & caching
Preview / staging environments
Deployment safety

Findings

GitHub Actions Pipeline (.github/workflows/ci.yml)

Triggers: push/PR to main/dev

Jobs:
1. docs-lint (parallel) - Validates markdown front-matter
2. lint (parallel) - Biome check
3. typecheck (parallel) - tsc
4. test (parallel) - Vitest
5. build (sequential) - Depends on all above

Service role key for worker operations
ADMIN_EMAIL_ALLOWLIST for admin access control
CRON_SECRET protects cron endpoints

Database Security

RLS on all tables
Ownership-based access (users see only their data)
Service role bypasses RLS (workers only)

Strengths

Runtime validation catches missing/invalid env vars
RLS prevents cross-user data access
Security policy documented (SECURITY.md)
Explicit scope boundaries defined

Weaknesses

No dependency scanning (Dependabot, Snyk, etc.)
No secret scanning (git-secrets, trufflehog)
