Run the accuracy-focused defaults:

bash
python solve_rsrp_maxscore.py \
  --data-root /path/to/dataset \
  --output /path/to/output.zip

Major additions over the uploaded solver include common-survey receiver coordinates, leakage-free cross-cell radio-map residual transfer, repeated group CV, additional ensemble diversity, a guarded residual stacker, and calibration that is rejected when it does not improve point-level OOF MAE. The original already contained strong cell-group CV, propagation features, physics-residual models, and robust blending. (solve_rsrp_457plus.py)

The global transfer uses ep.json station coordinates together with the relative signal and point-cloud coordinates specified by the challenge. (Challenge.26UCupSummer.ver.final (1).pdf) The script remains optimized around MAE, the stated primary scoring metric.

I syntax-checked it and completed a synthetic end-to-end run that produced and validated the ZIP structure. An exact 4512426+ result cannot be guaranteed without running against the actual dataset and hidden labels.
