# The unit tests for the Python helpers that decide what the rest of the
# pipeline does: scripts/affected_tests.py chooses which tests an MR builds,
# ci/scripts/test_cache.py chooses which of them can be skipped as already
# passed, and scripts/clang_tidy_hook.py decides which edit-time diagnostics
# interrupt an agent.  They fail closed, but a wrong answer is silent -- a job
# that skips too much or drops a hook diagnostic still reports success -- so
# these are blocking, and they run on every merge request rather than under the
# affected-tests label that gates select:tests (which is where the selector's
# tests used to run alone).
