# faststats/ reaches the wheel only through the `include` glob in pyproject.toml;
# nothing else imports it, so a missing package would pass every other gate
# silently. This must run against a wheel built from the sdist too (the release
# build_sdist job) — that path is what breaks if the include is wheel-scoped. See
# the include comment in pyproject.toml. ModuleNotFoundError means it stopped matching.
