"""Fail CI when the installed ROCm nightly wheels are too old.

Multi-arch nightly wheels are versioned like ``7.15.0a20260709`` where the
trailing eight digits after the alpha marker encode the build date
(``YYYYMMDD``). A stalled or broken nightly index would silently keep serving an
old build, so we parse that date from the installed package metadata and fail
when it is older than the allowed age. This turns "the nightly stopped
publishing" from a mystery into a loud CI failure.
