 # Changelog
 
+## Sprint 110 Map QA evidence drilldown (2026-06-25)
+
+- Extended the Map workspace QA/QC shortcut with inline evidence after comparing a saved derived selection dataset.
+- The result now shows quality-check id, matches, false positives, false negatives, mean IoU and QA warnings beside precision/recall/F1.
+- Added an `Open QA/QC evidence` handoff to the existing QA/QC workspace drilldown instead of creating a parallel QA detail system.
+- No backend API contracts, migrations, provider fetching, AI behavior or new product domains were introduced.

 ## Sprint 109 Map selection QA shortcut (2026-06-25)

+## Sprint 110 Map QA evidence drilldown (2026-06-25)
+
+Changed:
+- Extended `QaComparisonResult` frontend typing with optional `quality_check_id`, matching the existing backend QA result payload.
+- Updated `useMapSelectionQa` to keep the latest persisted map-selection quality-check id after a successful QA/QC comparison.
+- Extended the Map workspace QA/QC result state with inline evidence: quality-check id, matches, false positives, false negatives, mean IoU and QA warnings.
+- Added `Open QA/QC evidence` handoff from Map workspace to the existing QA/QC workspace drilldown, avoiding a parallel QA detail system.
+- Added compact styling for the Map QA evidence and warning surface.
+- Updated `frontend/README.md`, `CHANGELOG.md` and `docs/TODO.md`.
+- Added regression coverage in `backend/tests/test_sprint110_map_qa_evidence_drilldown.py`.
+
+Validation:
+- RED: `python -m pytest backend\tests\test_sprint110_map_qa_evidence_drilldown.py -q` failed before implementation because the hook/evidence wiring was absent.
+- `python -m pytest backend\tests\test_sprint110_map_qa_evidence_drilldown.py -q` passed: 2 tests.
+
+Limitations:
+- The Map evidence handoff opens the existing QA/QC workspace; selecting a specific historical check inside that workspace remains governed by the QA/QC panel's own latest-check behavior.
+- False-positive and false-negative geometries are summarized by persisted metrics/findings; dedicated map overlays for unmatched evidence remain future work.
+- No backend API contract, migration, provider fetching, AI dependency, real model behavior or new product domain was added.
+
+Next recommended pass:
+- Add optional unmatched-evidence map overlays once the QA persistence model stores explicit matched/unmatched feature ids or geometries.

 - After an area extract, `Save area export` persists the selected FeatureCollection as a normal Export Center artifact (`vector_selection_geojson`) so the handoff remains in project export history.
 - `Save as dataset` persists the same selected FeatureCollection as a derived vector dataset, selects it in the workbench and keeps it queryable through backend `vector_features` for later QA/QC or analysis.
 - Once a map selection has been saved as a derived dataset, the Map workspace can run QA/QC against a selected reference dataset without switching workspaces. The action reuses the existing QA comparison endpoint and shows precision, recall, F1 and persisted quality-check status inline.
+- Map selection QA results also show persisted quality-check id, matches, false positives, false negatives, mean IoU and QA warnings. `Open QA/QC evidence` hands operators to the existing QA/QC evidence drilldown for the full parameters/findings record.
 - The Data catalog shows a compact selected/reference/candidate/source summary and scan-friendly badges. Persisted `reference` datasets are shown as Reference, non-reference vector/GeoJSON layers are shown as QA Candidates for workbench scanning, and raster/other uploads remain Source.
 - Dataset cards explain the recommended next action and use compact two-line action buttons for inspect, map, export/QA and metadata refresh. Disabled actions keep a visible reason, such as `Vector/GeoJSON only`.
 - Raster controls show the latest generated tile manifest path from persisted `raster.tile` jobs and can hand that path directly to Detection Lab or Segmentation Lab with the selected raster dataset.
