 # Changelog

+## Sprint 173 Expanded building model promotion (2026-07-13)
+
+- Trained and fully gated the inactive `geointel-building-yolov8s-aoi1024expandedminpx4vis035e50-pt` candidate from the 20-source expanded real-data corpus.
+- The recommended `512` tile / `64` overlap / `0.15` confidence profile reached mean precision `0.6471`, recall `0.4700` and F1 `0.5433` across seven positive AOIs; all three pure-empty background AOIs remained at zero detections.
+- Compared fixed-threshold persisted evidence against the previous active model and reduced the false-negative rate in every validated positive AOI.
+- Activated the exact promoted local model through the guarded dry-run-first helper; no model was downloaded and no fake inference or QA result was introduced.
+- Updated Detection Lab operator profiles so the promoted expanded model is the recommended balanced review choice while the previous high-precision model remains available as a legacy conservative profile.
+- Persistent small-building misses remain the primary model-quality limitation and still require operator QA/QC.

 ## Sprint 172 CPU AI image build hardening (2026-07-12)

 - Reordered the Unraid all-in-one Docker build so backend source changes reuse the Python/GIS/AI dependency layer.
