fix(ci): satisfy sanitization + test-enumeration gates for #1129

Two gates added to CI after this branch was written:

- verify-sanitized: the harness header named the operator repo the
  live payload was captured from. Genericized; the payload itself
  was already synthetic.
- check-test-enumeration (#1017): the new harness was not on any CI
  surface. Enumerated in test:framework-shell beside its three
  ci-queue-wait siblings.

All four ci-queue-wait suites green; both gates green locally.
