+## Sprint 221 - Governed source freshness audit (2026-07-16)
+
+Implemented:
+- Added a project-level canonical source-freshness endpoint derived exclusively
+  from persisted Dataset, DatasetVersion and local storage evidence.
+- Defined explicit policies for GRB/VRBG/register snapshots, annual
+  population/land-use/agriculture/nature/water series, fixed DHMV/soil/thematic
+  editions, VMM scenarios, historical archives and local artifacts.
+- Added fail-closed classification for unknown sources and local integrity
+  checks for missing versions, checksum mismatches, missing files and stored
+  size disagreement.
+- Added a compact Status workspace panel and packaged
+  `audit_source_freshness.py` for explicit Unraid cron/reporting use.
+
+Boundaries:
+- No migration, provider call, background daemon, source download or automatic
+  Dataset refresh was introduced.
+- A fixed historical edition/scenario remains current evidence of that edition;
+  old publication dates alone are not treated as corruption or staleness.
+
+Validation:
+- Focused service, policy, canonical envelope, CLI and UI contract tests added.
+- Full release, live deployment and browser validation are recorded in the
+  delivery result after this implementation entry.
+
+Next:
+- Add machine-readable catalogue release probes only for providers with stable
+  official version endpoints, keeping every acquisition an explicit bounded
+  operator action.
