+# Sprint 151 - Runtime GIS upload and AOI1024 YOLO candidate
+
+## What changed
+
+- Fixed `scripts/train_operator_yolo_detector.sh` so the all-in-one image uses `/opt/geointel/venv/bin/python` by default when that AI venv exists. Explicit `PYTHON_BIN` still wins, and local shells still fall back to `python3`.
+- Raised the Nginx request body limit to `250m` in both `frontend/nginx.conf` and `deploy/unraid/nginx-all-in-one.conf` after the live 1024px GeoTIFF upload path returned `413 Request Entity Too Large`.
+- Kept the change runtime-only: no API contract, persistence model, migration, model-download behavior or default model selection changed.
+
+## What was tested
+
+- Red/green TDD guard for the training wrapper fallback:
+  - `python -m pytest backend\tests\test_sprint129_operator_yolo_training_dataset.py -q`
+- Red/green TDD guard for real GIS upload payload support:
+  - `python -m pytest backend\tests\test_docker_runtime_config.py::test_nginx_runtime_allows_real_gis_upload_payloads -q`
+- `bash -n scripts/train_operator_yolo_detector.sh`
+- Tower live model training on `/app/storage/operator-data/yolo-building-aoi1024-visible025`:
+  - output model: `/app/models/geointel-building-yolov8s-aoi1024visible025e50.pt`
+  - model asset id: `geointel-building-yolov8s-aoi1024visible025e50-pt`
+  - final Ultralytics validation: precision approximately `0.275`, recall `0.331`, mAP50 `0.188`, mAP50-95 `0.0716`
+
+## Known limitations
+
+- The AOI1024 tile audit is still `needs_attention`: median normalized box area is below gate and small-box share remains high.
+- Several dense 1024 GRB reference exports reached the current 1000-feature source cap. Treat those samples as useful but potentially reference-capped until the provider query path supports paging or smaller dense AOIs are chosen.
+- The trained model is intentionally inactive. It needs persisted detection QA/QC matrix evidence and background/hard-negative evidence before default promotion.
+
+## Next recommended pass
+
+- Rebuild/deploy the runtime upload-limit fix, rerun the four-sample AOI1024 persisted QA matrix, then decide whether label/source paging or additional AOI quality work comes before another training run.
