The conftest's pytest_sessionfinish writes per-cell tagged-union JSON
(compat-results.json) and the per-provider rate-limit summary to paths
controlled by COMPAT_RESULTS_PATH / COMPAT_RATE_LIMIT_SUMMARY_PATH.
The PR gate never set either env var, so the artifacts were written to
the working directory — but store_test_results only collects
test-results/junit.xml, leaving the per-cell JSON unreachable from the
CircleCI artifact browser. Reviewers triaging a red PR gate couldn't
pull the cell-level breakdown without re-running.
Point both env vars at a dedicated compat-artifacts/ directory and add
a store_artifacts step so the JSON blobs become downloadable. Also
extend the existing PR-gate wiring test to pin all three pieces:
COMPAT_RESULTS_PATH override, COMPAT_RATE_LIMIT_SUMMARY_PATH override,
and at least one store_artifacts step whose path matches the directory
the exports point at. Without the cross-check, a future refactor could
break the chain (e.g. only export the env vars, or only add the
store_artifacts step) and the wiring would silently drop the artifacts
again.
