+Release image `22fb8d51a9fde39552cf06a789174441631842b6-ai`
+passed the live read-only data-operations audit. It found zero missing direct
+database artifact references, left every critical table count unchanged,
+reported 2,002 bounded cleanup candidates (218,263,512 bytes) without deleting
+them and classified disk pressure as `ok` with approximately 725 GB free.
+The 224 missing historical manifest intermediates remain an explicit
+provenance warning and are excluded from cleanup decisions. National and
+maritime freshness evidence classifies all three fixed official editions as
+`current`, with zero due sources and zero integrity issues.
