Longitude first everywhere in `features.py`. + +**Zimbabwe bounds**: Lon 25.2–33.1, Lat -22.5 to -15.6 (enforced in `worker.py` validation). + +**Radius limit**: Max 5000m enforced in both API (`apps/api/main.py:90`) and worker validation. + +**RQ queue name**: `geocrop_tasks`. Redis service: `redis.geocrop.svc.cluster.local`. + +**API vs worker function name mismatch**: `apps/api/main.py` enqueues `'worker.run_inference'` but the worker only defines `run_job`. Any new worker entry point must be named `run_inference` (or the API call must be updated) for end-to-end jobs to work. + +**Smoothing kernel**: Must be odd — 3, 5, or 7 only (`postprocess.py`). + +**Feature order**: `FEATURE_ORDER_V1` in `feature_computation.py` — exactly 51 scalar features. Order matters for model inference. Changing this breaks all existing models. + +## MinIO Buckets & Path Conventions + +| Bucket | Purpose | Path pattern | +|--------|---------|-------------| +| `geocrop-models` | ML model `.pkl` files | ROOT — no subfolders | +| `geocrop-baselines` | Dynamic World COG tiles | `dw/zim/summer///DW_Zim___--.tif` | +| `geocrop-results` | Output COGs | `results//` | +| `geocrop-datasets` | Training data CSVs | — | + +**Model filenames** (ROOT of `geocrop-models`): +- `Zimbabwe_Ensemble_Raw_Model.pkl` — no scaler needed +- `Zimbabwe_XGBoost_Model.pkl`, `Zimbabwe_LightGBM_Model.pkl`, `Zimbabwe_RandomForest_Model.pkl` — require scaler +- `Zimbabwe_CatBoost_Raw_Model.pkl` — no scaler + +**DW baseline tiles**: COGs are 65536×65536 pixel tiles.

Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6.
