# Team artifact for test selection (smart CI, report-only until the oracles
# and the shadow comparison are green). Every push to main publishes the
# commit's bundle — its frozen graph, built incrementally from the previous
# bundle, and its per-test coverage map, re-run only for the suites the push
# selects — as the Actions artifact test-impact-<sha>. A weekly run rebuilds
# both from scratch and fails when the incremental graph differs from the full
# one. PR selection fetches the bundle of its merge base
# (scripts/ci/test-impact-bundle.sh) and never narrows on anything else.
