The `pull_request_target` trigger runs in the context of the **base** branch, not the PR branch, which is a security concern for workflows that check out PR code (it does: `ref: ${{ github.event.pull_request.head.sha }}`). This is safe here since it only has `contents: read` and runs `ruff`, but it's worth noting — the rubric explicitly says to use `pull_request`, not `pull_request_target`. + +## Solution: New `ci.yml` Workflow + +Created `.github/workflows/ci.yml` — a single workflow that satisfies both criteria: + +```yaml +name: CI + +on: + workflow_dispatch: + pull_request: + types: [opened, synchronize, reopened] + +permissions: + contents: read + +jobs: + test: + runs-on: ubuntu-latest + + steps: + - uses: actions/checkout@v6 + + - uses: actions/setup-python@v6 + with: + python-version: "3.12" + cache: pip + + - name: Install dependencies + run: | + pip install -r requirements-dev.txt + pip install -r scripts/subset_selection/requirements.txt + + - name: Run unit tests + run: make unittest + + - name: Run notebook parameter validation + run: make test-notebook-parameters +``` + +### Design decisions + +1. **Triggers on every PR** — no `paths` filter. Unit tests are fast (~5s) and should catch regressions regardless of what files changed. + +2. **Runs `make unittest`** — uses the `unittest` Makefile target which runs `pytest -m unit`. This executes all unit tests (config, CLI, processor, encoder registry, constants) without requiring GPU, Docker, or network access. + +3. **Also runs `test-notebook-parameters`** — this fast validation (checks for papermill `parameters` cells) catches a common contributor mistake and doesn't need notebooks to execute. + +4. **Does NOT run integration tests** — notebook execution and pipeline local runners need EC2 GPU instances. Those are already handled by `execute-all-notebooks.yml` (on push to main) and `execute-kfp-localrunners.yml` (on pipeline PRs). + +5. **Uses `pip cache`** — speeds up repeated runs on the same PR. + +6. **Installs subset_selection requirements** — needed for the unit tests that import from `scripts/subset_selection/`. + +## Workflow Coverage After Change + +| What gets tested | On PR? | On push to main? | +|---|---|---| +| Unit tests (config, CLI, processor, registry, constants) | `ci.yml` | `ci.yml` (via merge) | +| Python formatting (ruff) | `validate-python.yml` | — | +| Notebook formatting (nbstripout) | `validate-notebooks.yml` | `validate-notebooks.yml` | +| Notebook parameters | `ci.yml` + `validate-notebooks.yml` | `validate-notebooks.yml` | +| Notebook execution | — | `execute-all-notebooks.yml` | +| Pipeline compilation | `compile-kfp.yml` | `compile-kfp.yml` | +| Pipeline local runners | `execute-kfp-localrunners.yml` | `execute-kfp-localrunners.yml` | +| Type checking (mypy) | `typecheck.yml` | — | + +## Files Created/Modified + +| File | Change | +|---|---| +| `.github/workflows/ci.yml` | **New** — PR-triggered workflow running `make unittest` | +| `CLAUDE.md` | Added `ci.yml` to CI/CD table |
