SWISS24: all 25 hours, spatial deviation bands

All native stored cells, no masks; finite-first [M]. Blue: GPU-versus-original-CPU RMSE; orange: signed mean bias. Dark/light bands: spatial |error| p25–p75/p5–p95, not confidence intervals. No paired comparator is available; diagnostic GPU-versus-original-CPU only. Ratio row: deviation RMSE / pair RMSE where defined; reference lines1/2. The50% rule applies only to frozen D6 exceedance frames; zero denominators stay undefined. Dashed/off-scale arrow: unchanged D6 limit; hourly rain tau0 is undefined and its accumulated limit is informational.

Actualbe0 shippedSwiss24 against original CPU-WRF RD11. One unchanged raw24h report supplies both full-window andstrict24 reading; no annex or synthetic sidecar. Field limits/source/IC remain unchanged.; measured tree be0dd543c9f7f6d619a8b504348b11267ffe913f. All stored cells, no masks, finite-first. Blue line: GPU-versus-original-CPU RMSE. Orange: signed mean bias. Dark/light blue: spatial |error| p25–p75/p5–p95. No paired comparator is available for this standalone diagnostic GPU-versus-original-CPU comparison. No grey pair-spread curve or pair-RMSE ratio is reported. Dashed/off-scale arrow: frozen D6 RMSE limit; hourly rain uses the accumulated limit as an informational reference.

Ratio 2 = 50% pair/RC rule; a single pair is not a confidence interval. Ratio > 2 at small absolute error is expected where the CPU pair is near zero (early leads, d01); the 50% rule is applied only to D6 exceedance frames.

Summary n=1: cross-case sample SD is unavailable. Final summaries will show all cases and pointwise mean ± one sample SD per domain.
