+## 2026-08-09 - Model accuracy boundary and truthful evidence labels
+
+### Changed
+
+- Replaced the configured-YOLO Area-name substring gate with a fail-closed,
+  checksum-bound validation-scope manifest. The exact model SHA-256 must match
+  and the immutable EPSG:4326 scope geometry must cover the complete persisted
+  Dataset AOI. Renaming an Area can no longer widen model applicability.
+- Added an operator tool that builds the model-bound manifest from exact model
+  bytes and governed scope GeoJSON without overwriting prior evidence.
+- Corrected the detection UI: legacy Mol/Kempen profile scores are now labelled
+  historical calibration context, spatial independence is explicitly unproven,
+  and no profile is marked approved or promotion-ready.
+
+### Verified
+
+- Targeted backend/UI contract selection: 34 passed.
+- `git diff --check`: passed before the documentation update; final check is
+  part of the handoff verification.
+
+### Remaining limitations
+
+- The current active model is still not nationally validated. A new governed
+  corpus, independent spatial split, representative human review and immutable
+  product benchmark remain required before any production-accuracy claim.
+- Every deployed model asset needs its own generated scope manifest and exact
+  configured manifest checksum before enforced inference is available.
