fix: clarify active AI result context

CHANGELOG.md

@@ -18,6 +18,7 @@
 - Detection QA now applies the persisted tile coverage through the existing GiST-indexed PostGIS geometry column before loading reference rows, while retaining the complete reference population in audit counts.
 - The unchanged exact IoU matcher now uses a Shapely spatial index to avoid testing geometries whose envelopes cannot intersect.
 - Clarified the primary map source and legend whenever an AI result is active so detections are never presented as the underlying official GRB source.
+- Made the fixed workbench context bar follow the active AI layer and exposed the IoU match threshold beside every detection-QA score.

 - Focused detection, coverage, QA and guided-workflow tests passed.
 - Frontend TypeScript typecheck passed after the source/legend correction.
 
+Live operational proof:
+- The final repository readiness gate passed 578 backend tests, API/document audits, frontend typecheck/build, one Alembic head and all shell smoke checks.
+- Deployed commit `0cad8fd` to the Tower all-in-one runtime with AI extras enabled. Health, PostGIS 3.6, the single migration head, required schema/indexes and the port-1202 browser proxy all passed.
+- The bounded QA request completed in 1.82 seconds. It retained a raw GRB population of 466,078, materialized/evaluated 1,826 coverage features and excluded 464,252 outside the nine persisted tiles.
+- At match IoU 0.25, persisted quality check `341b0076-663a-4427-8a36-d5d9247a730e` measured 1,186 matches, precision 0.6073, recall 0.6495, F1 0.6277 and mean IoU 0.4565. No metric was fabricated.
+- A separate UI run at its default stricter match IoU 0.50 also completed and persisted quality check `7a4464cd-152d-424f-a2b9-ed321b91524c`; the lower F1 is now explained by displaying the threshold beside the score.
+- In-app browser inspection confirmed 1,953 persisted rows, map rendering over OpenStreetMap and explicit `AI-detecties`, `Detectierun`, `Gevonden gebouwen` and `controle vereist` labels.
+
 Next:
-- Deploy the bounded QA correction, rerun the live persisted detection-versus-GRB comparison, verify persisted metrics and inspect the result in MapLibre before declaring the guided operational flow complete.
+- Add bounded operator-triggered orthophoto acquisition from a drawn map rectangle, then hand that raster to this proven guided pipeline. Keep external acquisition out of browser/startup paths and retain explicit source licensing/provenance.
