+# PR CI for PyAutoHands's own test suite
+
+Shipped: PyAutoLabs/PyAutoHands#230 (squash-merged as `6d5d608`, 2026-08-05).
+
+PyAutoHands had **28 test modules / ~300 tests and zero PR checks**. None of its
+three workflows was triggered by `pull_request`: `python_matrix.yml` is a weekly
+cron over the five *libraries'* suites, `navigator_check.yml` is
+`workflow_call`-only, and `release.yml`'s `python3 -m pytest` runs inside
+`${{ matrix.project.path }}` — a matrix of the five libraries, with PyAutoHands
+checked out beside them only as a helper, so `tests/` was never collected. A
+Hands PR's only gate was whatever the authoring session happened to run locally.
+
+That matters more here than for a leaf repo: `build_util` and `env_config`
+execute every workspace smoke run and every release build, so a regression
+surfaces as a mysterious workspace-CI failure three repos away.
+
+Added `.github/workflows/tests.yml` on the shape of the two existing organ
+self-test gates (PyAutoBrain `tests.yml`, PyAutoHeart `heart-tests.yml`) —
+`push: [main]` + `pull_request`, Python 3.12/3.13/3.14, pytest only,
+`cancel-in-progress` restricted to non-`main` refs. PyAutoHands is now the third
+organ with a self-test gate; Gut still has none (no workflows at all).
+
+## Findings worth keeping
+
+**The dependency set is not what reading the source suggests.** PyAutoHands has
+no `pyproject.toml`, so there is no `.[dev]` extra to install the way
+`heart-tests.yml` does, and `pytest` is not in `requirements.txt`. Derived
+empirically by starting from `pytest --collect-only` in a clean venv and adding
+one package at a time, the real set is `pytest PyYAML ipynb-py-convert Pillow`.
+Two traps: `nbformat`/`nbconvert` look required from the imports but are **not**
+(tests self-skip on their absence), while **`ipynb-py-convert` is needed as a
+CLI binary** `build_util` shells out to — not as an import, so no amount of
+reading import statements finds it. Naming packages explicitly beats
+`-r requirements.txt`, which drags in `jupyterlab` + `ipykernel` and turns a 6s
+gate into a slow one.
+
+**The gate immediately paid for itself.** The suite was not green: 9 failures.
+Seven were the missing dependencies. Two were real —
+`tests/test_python_matrix_workflow.py` still asserted that Python 3.14 lives in
+an isolated `experimental_python_314` job with `continue-on-error: true`, but
+`b038fdc` ("promote Python 3.14 to required matrix legs", following the
+PyAutoFit#1439 forkserver fix) had deliberately promoted 3.14 into the required
+unit + smoke matrices and retired that job, updating `summary.needs` and the
+banner text to match — but not the test guarding the contract. It had been
+failing unnoticed for five days because nothing ran it. **A deliberate CI-policy
+change orphaned its own guard test and nothing reported it** — which is the
+argument for the gate, discovered by building the gate.
+
+The workflow was correct and the test stale, so the test was updated to the
+promoted shape rather than the workflow reverted (human-confirmed: 3.14 required
+is the intent). Worth noting the general shape of that judgment — "never edit a
+test to mask a regression" is the right default, and the evidence that overrode
+it here was that the commit message stated the promotion as intent, referenced
+the upstream fix that unblocked it, and left `python_matrix.yml` internally
+consistent (`summary.needs` and banner both updated). Only the test lagged.
+
+**Python 3.14 was declared but never exercised on Hands's own code.** Verified
+clean before adding it to the matrix — CI ran real 3.14.6 (301 passed, 4
+skipped, ~6s, identical profile to 3.12/3.13). Added
+`test_self_test_gate_tracks_the_supported_python_set`, asserting `tests.yml`'s
+matrix equals `python_matrix.yml`'s required `unit_tests` matrix, so promoting
+or dropping a version has to touch both files. Checked the assertion is not
+vacuous — both sides parse to non-empty lists.
+
+**A green tick hid a coverage hole, and CI/local disagreement is how it
+surfaced.** CI reported 301 passed / 4 skipped against a local 302 / 3. Same
+total, so nothing was missing, but one test that passes locally *skips* in CI:
+`test_workspace_config_precedence.test_actual_workspace_files_exist` walks
+`repo_root.parent / <workspace>` asserting each of the six workspaces owns its
+`config/build/{no_run,profile_smoke,visualise_notebooks}.yaml`, and skips at the
+first one absent. In a full local workspace it asserts all six; in CI's bare
+checkout it asserts nothing. Left open deliberately — closing it means six extra
+checkouts for a repo-layout invariant, coupling a 6s gate to six other repos —
+but stated in the workflow header rather than hidden. **Generalisable habit:
+compare CI's pass/skip counts against the local baseline rather than accepting
+the green.**
+
+## Trap for next time
+
+`lifecycle.py record --prompt` only folds prompts from `active/`. This task
+never went through `/create_issue` → `active/` (the work was done in the same
+session that filed the prompt), so the draft was folded into this record by hand
+and `draft/test/pyautohands/pr_ci_for_own_test_suite.md` removed explicitly.
+
+## Original prompt
+
+# PyAutoHands PRs run zero checks — gate its own test suite on `pull_request`
+
+Type: test
+Target: pyautohands
+Repos:
+- PyAutoHands
+Difficulty: small
+Autonomy: supervised
+Priority: normal
+Status: formalised
+
+`@PyAutoHands/tests/` holds **28 unit-test modules** covering the executor's
+core logic — `build_util` (script/notebook execution, per-script timeouts,
+clean-skip exit codes), `env_config` (profile discovery, per-script env
+building, JAX marking, workspace config precedence), `result_collector`,
+`check_navigator`, `clone_seed.substitute`, `generate_release_notes` /
+`slack_release_notes`, `bump_colab_urls`, `repro_command`, and the
+`python_matrix` workflow parser.
+
+**None of it runs in CI.** PyAutoHands has exactly three workflows and not one
+of them is triggered by `pull_request`:
+
+| Workflow | Trigger | What it actually tests |
+|---|---|---|
+| `python_matrix.yml` | `workflow_dispatch` + weekly cron (Mon 03:00 UTC) | the **five libraries'** suites (`test_autonerves`, `test_autoarray`, …) on 3.12/3.13/3.14 — never `tests/` |
+| `navigator_check.yml` | `workflow_call` only | reusable catalogue check invoked by the *workspaces* |
+| `release.yml` | `workflow_dispatch` (driven by Brain's nightly-release) | the `release_test_pypi` job's `python3 -m pytest` runs inside `${{ matrix.project.path }}`, whose matrix is PyAutoNerves/PyAutoFit/PyAutoArray/PyAutoGalaxy/PyAutoLens. PyAutoHands is checked out beside them as a *helper*, so its own `tests/` are never collected. |
+
+`grep -rn "pull_request" .github/workflows/` returns nothing. So a PyAutoHands
+PR carries **zero check runs**, and its only gate is whatever the authoring
+session happened to run locally — the same hole PyAutoBrain had before
+`tests.yml` and PyAutoHeart had before `heart-tests.yml`.
+
+This matters more here than for a leaf repo: PyAutoHands is the **Hands** —
+`build_util` and `env_config` are what execute every workspace smoke run and
+every release build. A regression in `timeout_for` or `build_env_for_script`
+surfaces as a mysterious workspace-CI failure three repos away.
+
+## What to do
+
+Add `@PyAutoHands/.github/workflows/tests.yml`, mirroring
+`@PyAutoBrain/.github/workflows/tests.yml` and
+`@PyAutoHeart/.github/workflows/heart-tests.yml` — they are the two
+established organ-self-test gates and this should be the third of the same
+shape, not a new pattern:
+
+- `on: { push: { branches: [main] }, pull_request: }` — one run per commit.
+- `concurrency: { group: hands-tests-${{ github.ref }}, cancel-in-progress: ${{ github.ref != 'refs/heads/main' }} }`.
+  **Keep the `!= main` condition**: a cancelled run on `main` reads as red CI,
+  because `cancelled` is in Heart's `FAILURE_CONCLUSIONS`.
+- Matrix `python-version: ["3.12", "3.13"]`, `fail-fast: false`.
+- Run `pytest tests/ -q` from the repo root.
+
+**Deliberately pytest only.** It must not invoke `autohands generate` /
+`run_all` / `pre_build`, and must not reach the network or check out a
+workspace — those need live sibling checkouts and belong to the release and
+scheduled drivers, not to a PR gate. Both sibling workflows carry that
+constraint as a header comment; write the equivalent here, naming what this
+gate does *not* cover.
+
+### The dependency set is the one real unknown
+
+PyAutoHands has **no `pyproject.toml`** — it runs from its checkout, so there
+is no `.[dev]` extra to install the way `heart-tests.yml` does. `pytest` is not
+in `requirements.txt` either. The modules under test pull third-party imports
+at import time: `yaml` (`env_config`), `nbformat` and
+`nbconvert.preprocessors.ExecutePreprocessor` (`build_util`). So the install
+step needs roughly `pip install pytest PyYAML nbformat nbconvert` — but derive
+the real set empirically rather than trusting that list:
+
+1. Create a clean venv, install nothing but `pytest`, and run
+   `pytest tests/ --collect-only`. Add packages one at a time until collection
+   succeeds, then until the suite runs.
+2. Prefer naming the packages explicitly in the workflow (PyAutoBrain's
+   approach: `pip install pytest PyYAML`) over `-r requirements.txt`, which
+   drags in `jupyterlab` and `ipykernel` and would make a ~30s gate slow.
+3. If a test turns out to need something genuinely heavy, that is a signal the
+   test should be isolated or marked — say so rather than bloating the gate.
+
+### Establish the green baseline first
+
+The suite has never been run by CI, so **do not assume it is green**. Run it
+locally on 3.12 and 3.13 before writing the workflow. If entries fail:
+
+- A **real** failure (stale API, drifted expectation) → fix it in the same PR
+  if it is small and obvious; otherwise split it out and say so.
+- Never weaken an assertion or delete a test to reach green. If something is
+  genuinely broken in `autohands`, that is a `bug/pyautohands/` prompt, and
+  this task lands the gate around whatever is passing plus a filed follow-up.
+
+Report the baseline in the PR: how many tests, how long, on both versions.
+
+## Out of scope
+
+- **Coverage gates / thresholds.** No sibling organ gate enforces one; do not
+  introduce the pattern here.
+- **Running the ecosystem-facing entrypoints in CI** (`generate`, `run_all`,
+  the navigator regeneration). Those are release-path concerns.
+- **Adding a `pyproject.toml`** to PyAutoHands. Packaging PyAutoHands is a
+  separate decision with its own blast radius; this task installs deps
+  explicitly in the workflow and leaves the repo un-packaged.
+- **Touching `python_matrix.yml`.** Its weekly library sweep is a different
+  job with a different purpose; leave it alone.
+
+## Done when
+
+- A PyAutoHands PR shows a passing `pytest (3.12)` / `pytest (3.13)` check pair.
+- `main` pushes build the same workflow (so Heart's `ws_ci` rollup, which reads
+  main-HEAD conclusions, has something to read for this repo).
+- The workflow header states what the gate deliberately does not run.
