+"""Tests for the launch-time stale-bytecode sweep (checkout fingerprint guard).
+
+Bug class: the checkout's ``.py`` files change (``hermes update``, manual
+``git pull``, ZIP update) while ``__pycache__`` retains bytecode compiled
+from the previous revision; the next process to import trusts the stale
+``.pyc`` and dies with ``cannot import name ...`` (#6207, #60242).
+
+The launch-time guard compares the current checkout fingerprint against the
+last-validated stamp and sweeps ``__pycache__`` once when they diverge —
+covering paths no update-time clear can reach (manual pulls, pre-hardening
+updaters).
