- Guard prepare script for Docker builds without .git
- Add pre-push hook for heavier quality gates (typecheck/test/build)
- Pin drizzle-orm version in scripts/package.json
- Add E2E_SMOKE_ALLOW_WRITE opt-in guard via e2eEnv abstraction
- Create @household/config env-e2e.ts using same t3-env + zod pattern
- Make e2e teardown robust with optional chaining + allSettled
- Fix markdown code block language identifier (MD040)
- Fix CI integration docs to reflect actual workflow
