+## 2026-07-18 - Belgium/North Sea RC-10 data operations and retention
+
+Implemented:
+
+- Added a read-only data-operations audit for storage lifecycle, disk pressure,
+  persisted artifact references, failed work and national, regional and
+  maritime source families.
+- Added dry-run-first cleanup restricted to explicit derived/cache categories.
+  Apply mode requires an exact confirmation token, a recent checksum-verified
+  release backup and a bounded delete ceiling.
+- Mounted release backups read-only and protected release evidence, official
+  source editions, originals, uploads, model assets, operator evidence and
+  unknown paths from cleanup.
+- Hardened artifact discovery for large production tables with bounded SQL
+  counts and distinct-path queries, strict manifest field traversal and
+  separate current-reference and historical-manifest findings.
+- Classified fixed NGI and RBINS national/maritime editions so old publication
+  dates are not mislabeled as stale.
+
+Validation:
+
+- Repository readiness passed backend compilation, 1,021 backend tests,
+  16 frontend tests, frontend typecheck/build and Alembic head
+  `202607160001`; focused final policy tests passed 19/19.
+- Immutable image
+  `22fb8d51a9fde39552cf06a789174441631842b6-ai` deployed healthy with
+  PostgreSQL/PostGIS and the expected migration.
+- The exact live image passed
+  `scripts/run_rc10_data_operations_audit.sh`: disk pressure `ok`, zero missing
+  direct database references, 2,002 dry-run candidates totaling 218,263,512
+  bytes and unchanged critical table counts.
+- The audit retained 224 unavailable historical manifest intermediates as a
+  non-destructive provenance warning. No cleanup was applied.
+- Live national/maritime freshness evidence reports three current sources,
+  zero due/review-required sources and zero integrity issues.
+
+Decision:
+
+- RC-10 is complete. RC-11 final release packaging and acceptance is active.

-**State: in progress.**
+**State: complete.**
+
+Release image `22fb8d51a9fde39552cf06a789174441631842b6-ai`
+passed the live read-only data-operations audit. It found zero missing direct
+database artifact references, left every critical table count unchanged,
+reported 2,002 bounded cleanup candidates (218,263,512 bytes) without deleting
+them and classified disk pressure as `ok` with approximately 725 GB free.
+The 224 missing historical manifest intermediates remain an explicit
+provenance warning and are excluded from cleanup decisions. National and
+maritime freshness evidence classifies all three fixed official editions as
+`current`, with zero due sources and zero integrity issues.
