Khalim Conn-Kowlessar c496f345f8 slice 14l: bigger-run fixes — UCL guard, PV Measurement coercion, sMAPE ... Three changes surfaced by the 25k 2026 run: - transform._peui_ucl returns None for non-positive raw PEUI (net-exporters). apply_ucl_correction would otherwise raise ValueError on negative input. - PhotovoltaicArray scalars (peak_power, pitch, orientation, overshading) now accept Measurement | int | float in the schema; mapper coerces via _measurement_value. - train_baseline reports sMAPE alongside MAPE — handles zero-actual rows (e.g. co2_emissions for net-zero certs) where MAPE explodes. Results at N=25,000 RdSAP 2026 certs (~32s end-to-end): sap_score MAPE=0.064 sMAPE=0.054 R^2=0.762 co2_emissions sMAPE=0.140 R^2=0.890 peui_raw MAPE=0.126 sMAPE=0.120 R^2=0.714 peui_ucl MAPE=0.114 sMAPE=0.108 R^2=0.736 space_heating_kwh MAPE=0.167 sMAPE=0.157 R^2=0.915 hot_water_kwh MAPE=0.089 sMAPE=0.086 R^2=0.737 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-16 21:15:37 +00:00
