- createPendingAuditLog/markAuditCommitted/markAuditFailed implement the pending -> committed/failed lifecycle (D-07, SC-3); markAuditFailed always sanitizes via sanitizeAwsError
- insertPulseCrudHistory writes 'pulse_crud' history rows, documented as callable only after a committed write
- upsertMirrorRecord/softDeleteMirrorRecord/loadMirrorRecord manage the route53_records mirror; mirror writes are best-effort and soft-delete only (D-08), audit/history writes are not best-effort
- log same pre-existing itglue-search.test.ts failures (unrelated, out of scope) in deferred-items.md
