+## Autonomous Belgium and North Sea RC program (2026-07-17)
+
+- Expanded the release-candidate geography from Mol/Kempen to all of Belgium
+  and the Belgian North Sea while retaining the existing areas as golden
+  regression references.
+- Added an executable autonomous RC-0 through RC-11 roadmap and explicit
+  national/maritime scope freeze.
+- Folded fresh-install, upgrade, rollback and runtime proof into RC-5 and
+  RC-11 instead of creating a separate RC-12 phase.
+- Added a read-only release-evidence manifest command with Git, migration,
+  dependency, configuration checksum and optional live endpoint evidence.
+- Replaced the obsolete pre-build status with the current implemented
+  foundation and active release blockers.
+- Added atomic PostgreSQL release backup, read-only checksum verification and
+  isolated generated-database restore-smoke tooling.
+- Split health into process liveness and fail-closed readiness covering
+  PostgreSQL, PostGIS, Alembic head and writable storage.
+- Made system capabilities report real PostGIS and configured local YOLO
+  state, added request IDs and exception logging, reduced SQL engine logging,
+  and terminalized impossible orphaned work after all-in-one restarts.
