ci: run the repo-level guard tests, and find them by glob - #306
Conversation
Five guards under scripts/ have never run in CI:
test_schedule_window_plumbing.py
test_odds_fetch_scope.py
test_property_order_coverage.py
test_scroll_cache_rebuild.py
test_odds_centre_collision.py (on its branch, not yet merged)
The structure workflow names its three by hand, so a guard added later is
simply not picked up, and nothing reports that. Each of these protects a
regression that was found on live hardware -- the schedule window silently
pinned to defaults, odds fetched for 946 games to display one, 26 settings
unreachable in the web UI, a scroll cache that never rebuilt -- and any of them
could have come back without a single check failing.
Discovered by glob rather than listed, so the next one runs the day it lands.
The step fails if the glob matches nothing, since "no guards found" and "all
guards passed" would otherwise look identical, which is the same failure mode
as the enumeration.
Placed in the safety workflow rather than the structure one because several
guards import a plugin's modules, which pull in the core, and this is the job
that checks core out. They are written to skip cleanly when core is absent, so
running them without it would report success while checking nothing.
The workflow's paths now include scripts/** and the workflow itself. Without
that a PR touching only a guard matches no path, the workflow never runs, and
the guard merges without ever having executed -- which is how this happened.
All seven guards on main pass when run the way the step runs them. The
failure path is verified too: a failing guard fails the step and is named.

Handle the schedule guard's skip status.
scripts/test_schedule_window_plumbing.py exits with status 2 when LEDMATRIX_CORE is unavailable, but this loop treats every nonzero status as failure. Accept status 2 as a skip and fail on status 1 or other errors.

scripts/test_schedule_window_plumbing.py exits 2 when it cannot find a
LEDMatrix core checkout:
print("SKIP: no LEDMatrix core checkout found (set LEDMATRIX_CORE)")
sys.exit(2)
The loop ran it as `if python "$guard"`, so every nonzero status counted
as a failure and that skip would have been reported as "guard failed".
The core is checked out earlier in the job and LEDMATRIX_CORE is set, so
this does not fire today. It matters because the step is `if: always()`:
a failed core checkout still runs the guards, and the job would then
blame the guard rather than the checkout that actually broke. That is a
misleading error in the exact situation where a clear one is worth most.
Status is now captured explicitly -- 0 passes, 2 skips with a ::notice,
anything else fails with the status in the message. The bare invocation
needs `set +e` around it because Actions runs `run:` under `bash -e`,
which is why the original used `if` in the first place.
Verified by extracting the loop and running it under `bash -e` against
three fake guards exiting 0, 1 and 2:
ok + skip + fail -> failed: test_fail.py, exit 1 (fail still fails)
ok + skip -> STEP PASSED, exit 0 (skip does not)
and the failing guard no longer aborts the loop before later guards run.

Reviewed as a reviewer, and specifically tried to break the thing this PR depends on: that python scripts/test_<x>.py actually checks something. A globbed runner is only as good as the guards it finds, and the obvious failure mode is a pytest-style file with def test_* and no __main__ — python file.py would import it, run nothing, and exit 0. A green step that checks nothing is worse than no step.
Checked all of them. All nine are standalone-runnable with a __main__ block and a nonzero exit path, so the glob approach holds:
test_check_manifest_version_fields.py test_odds_fetch_scope.py
test_check_scroll_adoption.py test_property_order_coverage.py
test_check_sports_display_contract.py test_schedule_window_plumbing.py
test_logo_cache_key_consistency.py test_scroll_cache_rebuild.py
test_odds_centre_collision.py
Also confirmed the dependency question, because it's the one that would make this flaky rather than wrong. Several guards import plugin modules that need PIL and pytz, and the per-plugin pip install -r requirements.txt in the harness step only runs for changed plugins — so a PR touching one unrelated plugin could plausibly hit ModuleNotFoundError and report it as a plumbing failure. It doesn't: the setup step runs working-directory: core and core's requirements.txt carries Pillow>=12.2.0 and pytz>=2024.2, so the guards have their imports regardless of which plugin changed. (I hit exactly this locally with those two missing and got a very convincing FAILED: 10 check(s) out of test_schedule_window_plumbing.py — worth knowing that's what a missing-dep failure looks like.)
Two notes, neither blocking:
1. The table in the description is missing a guard. It lists eight; there are nine. test_logo_cache_key_consistency.py isn't in it — worth adding so the "five never ran" count is checkable against reality.
2. The exit-2 skip convention isn't uniform, and the comment implies it is. The step's comment presents status 2 as the general "skipped, and said why" contract, but only test_schedule_window_plumbing.py actually implements it. The others exit 1 on a missing prerequisite — test_odds_centre_collision.py just raises ModuleNotFoundError and dies with a traceback.
That's harmless today, since core's requirements cover what they import. It stops being harmless the moment a guard imports a plugin module needing a dep that lives only in that plugin's requirements.txt (paho-mqtt, say) — then an unrelated PR goes red with a stack trace pointing at the guard rather than at the missing install. Given the step's whole thesis is "distinguish 'checked nothing' from 'checked and passed'", the same distinction is worth having for 'couldn't check': catching ImportError at the top of each guard and exiting 2 would make the convention real rather than documented.
The three deliberate details in the description — failing on an empty glob, living in the safety workflow rather than the structure one, and adding scripts/** to paths — all check out. The paths addition in particular is load-bearing and easy to miss: without it this PR could not have run its own new step.
Found by asking whether the guards I'd been adding actually run. Five of them never have.

test_check_manifest_version_fields.pytest_check_scroll_adoption.pytest_check_sports_display_contract.pytest_schedule_window_plumbing.pytest_odds_fetch_scope.pytest_property_order_coverage.pytest_scroll_cache_rebuild.pytest_odds_centre_collision.pyThe structure workflow names its three by hand, so a guard added later is simply not picked up, and nothing reports that.
test_schedule_window_plumbing.pyhas been in this position since #293.Each of these protects a regression found on live hardware — the schedule window silently pinned to defaults, odds fetched for 946 games to display one, 26 settings unreachable in the web UI, a scroll cache that never rebuilt. Any of them could have come back without a single check failing.
The fix
A step that discovers guards by glob rather than listing them, so the next one runs the day it lands.
Three deliberate details:
pathsnow includesscripts/**and the workflow itself. Without that, a PR touching only a guard matches no path, the workflow never runs, and the guard merges having never executed — which is exactly how this happened.Verification
