 # Changelog
 
+## Sprint 197 Measured detection accuracy and durable review (2026-07-15)
+
+- Re-ran the active local building model at confidence thresholds `0.10` and
+  `0.15` over independent Mol holdouts in Achterbos, Gompel, Donk and Postel,
+  plus the pure-empty Postel forest control. Threshold `0.15` retained the best
+  F1 in every positive zone and both thresholds produced zero forest-control
+  detections, so no speculative threshold or model promotion was made.
+- Aligned the map-driven building QA flow with the documented operational
+  footprint match IoU `0.25`. The map now reports candidate count, matches,
+  precision, recall, F1, false positives and false negatives instead of
+  presenting every model box as a recognized building.
+- Added first-class `detection_reviews` persistence and canonical project QA
+  endpoints for paginated false-positive/false-negative review decisions.
+- Added a focused frontend review queue with role/status filters, notes,
+  pagination and map handoff. Unreviewed or alignment-mismatch evidence cannot
+  silently become hard-negative training data.
+- Bounded QA evidence resolution to the persisted evidence identifiers instead
+  of loading complete regional reference datasets into application memory.
+- Added regression coverage for migration alignment, decision validation, API
+  envelopes, bounded evidence access and the map QA threshold.
+- Passed the complete readiness gate with 592 backend tests, 88 documented API
+  routes, one Alembic head and a green frontend typecheck/production build.

 ## Sprint 196 Map-driven official orthophoto analysis (2026-07-15)
 
 - Added an explicit bounded endpoint for the official Digitaal Vlaanderen
