# Epic objective

Get the repo to a place where `pnpm test` is a real command and a PR can't merge with broken lint/types/tests. Today there is no test runner (`AGENTS.md` is explicit about this) and no CI workflow.

## In scope / out of scope

**In scope**

- Add Vitest to the workspaces that need it most: `packages/database`, `packages/shared`, `packages/ai`.
- Add a `pnpm test` script wired through Turborepo so cached test runs work.
- Add `.github/workflows/ci.yml` running `pnpm lint && pnpm type-check && pnpm test` on PRs.

**Out of scope**

- Testing React components. Component testing in Next.js + React 19 + RSC is its own rabbit hole; defer until there's a real motivating bug.
- End-to-end (Playwright) tests. Same reason.

## Related tasks

| Task | Link |
|------|------|
| Bootstrap Vitest and GitHub Actions CI | `./Task-bootstrap-vitest-and-ci.md` |

## Dependencies

- Depends on: `Task-fix-lint-and-shared-types` from `Plan-daily-driver-finish` (CI needs lint + type-check to be green).

## Acceptance criteria

- [ ] `pnpm test` runs Vitest across at least 3 packages.
- [ ] CI workflow gates PRs on lint + type-check + test.
- [ ] At least 3 real tests exist (one in each chosen package) that catch a real regression if their target code is broken.

## Proposed timeline

| Phase | Window | Notes |
|-------|--------|-------|
| Vitest + first tests | Day 1 | Set up runner, write seed tests. |
| CI workflow | Day 2 | Pin Node 20, run lint/type/test on PR. |
