+### Source freshness audit
+
+Source freshness is derived state and does not introduce a scheduler or status
+table. `Dataset.source_name`, `imported_at`, `observed_at`, `source_version`,
+checksum/storage metadata and immutable `DatasetVersion` rows remain the
+persistence source of truth. The project source-freshness service groups those
+records under explicit publication policies and performs a read-only local
+evidence audit. External catalogue checks and refresh jobs remain explicit
+operator actions; they may never overwrite a fixed edition or scenario in
+place.
