Skill — temperature
Blenders vs ERA5 truth + EGTE METAR and Taw Green obs (both lower than the 393 m tor → expect a warm bias).
Vs truth
Phase 2b lean (13 features)
Six per-model temperatures, their mean/std/range, and cyclical hour/day-of-year encodings. The original champion.
Phase 2d exact-runtime (T2, leads 12+24)
Per-cycle exact init time + lead, GFS+AIFS required, IFS+MO Global optional. Champion at lead 12; challenger at lead 24. Sparse panel until verify catches up (~5d ERA5 latency).
