"""Regressions for the isolation holes an adversarial review of M1+M2 found.

Every test here corresponds to a defect that was real on this branch before
the hardening commit. They are grouped by the shape of the mistake, because
that shape is the thing worth remembering:

  * a guard wired to ONE call site of several (artifact bytes were checked by
    path inside `_api`, while `/preview/` dispatches before `_api` and
    version-/filename-addressed serves never match the path pattern);
  * a resource family with NO guard at all (`/projects/*`);
  * a cheap substring pre-check that a generic new word turns into a
    single-user regression (`host.query`).

All passwords/tokens are fake test values.
