 - The script writes per-run logs and a `quality_matrix_summary.json` with detection count, QA score, precision, recall, F1, mean IoU, matches, false positives and false negatives.
 - The summary ranks `best_by_score`, `best_by_recall` and `best_by_precision` for operator model-quality decisions.
 - Added readiness syntax coverage and static regression coverage for the quality matrix contract.
+- Ran the matrix on Tower against the Geel operator sample: `yolov8n-building-segmentation-pt` with tile `512`, overlap `64` and threshold `0.15` ranked best by score/recall with 80 detections, 6 matches, 74 false positives, 611 false negatives and F1 `0.017216642754662843`; generic `yolov8n-pt` produced zero building detections.

 Open:
-- Live Tower matrix run still needed against the current Geel operator sample.
+- None for matrix tooling.
 
 Limitations:
 - This is operator benchmarking tooling only. It does not change inference behavior, add model downloads, seed fixture detections, fetch providers, change API contracts or change migrations.
 - A single Geel sample is not enough to declare a production V1 building-extraction baseline; additional orthophoto/reference samples are still needed before picking defaults.
 
 Next recommended pass:
-- Run the matrix on Tower for the current Geel operator sample, then decide whether the active building model should remain the default evaluation model or be replaced.
+- Add at least two more local orthophoto/reference samples and run the same quality matrix before choosing V1 defaults; the current Geel evidence says runtime plumbing works, but the active model is still not extraction-quality.
