## Source

```yaml
# .github/workflows/ci.yml
name: CI

on:
  push:
  pull_request:

jobs:
  core:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: oven-sh/setup-bun@v1
        with:
          bun-version: "1.3.4"
      - name: Install
        run: bun install --frozen-lockfile
      - name: Typecheck
        run: bun run typecheck
      - name: Test
        run: bun test
```

## Notes

- Uses `oven-sh/setup-bun` for fast Bun-based CI.
- `--frozen-lockfile` pins exact dependency versions.
- Typecheck and tests run as separate steps -- type errors surface even if tests pass.
- Triggers on all pushes and pull requests with no branch filtering.
