#113: AuditLogPartitionMaintenance (monthly SPLIT RANGE) and the backfill-source-node endpoint now use the AuditLog:MaintenanceConnectionString login when set (unset = unchanged). Migration AuditMaintenanceGrants gives scadabridge_audit_purger ALTER ANY DATASPACE and column-level UPDATE (SourceNode). #114: archive cleanup deletes the writer's own *.tmp files and manifest-less data files older than 24 h inside {Directory}/{YYYY} (DeletedOrphan, dry-run aware). #115: head-export failures bump scadabridge.audit.chain_head_export.failures and Degrade the /health/ready entry audit-chain-head-export (failing or stale > 2 intervals).
