Khalim Conn-Kowlessar 7e1269fc8e Handover: hand-built fixture skeleton landed (Slice 62); 2/11 pins green ... Update NEXT_AGENT_PROMPT.md with the pivot to the rigorous cohort pattern: cert 001479's hand-built `_elmhurst_worksheet_001479.py` becomes the ground-truth EpcPropertyData. Cross-mapper parity work then collapses to "both mappers produce hand-built-equivalent EpcPropertyData". Two parallel workstreams documented: 1. Iterate the hand-built skeleton (Slice 62) until all 11 cascade pins hit 1e-4. Current state: 2/11 green (pumps_fans, lighting); sap_score_continuous gap −3.02 SAP. Likely next slices: HW demand routing, §2 ventilation tuning, thermal mass parameter, multiple- glazed proportion. 2. Once hand-built is GREEN, add `test_elmhurst_mapper_matches_hand_ built` + `test_api_mapper_matches_hand_built` over the 7-cert cohort (000474..000516 + 001479). Every field diff = mapper bug to close. Cross-parity collapses to "both mappers produce hand-built-equivalent". Documents the M-vs-L Ext1 age-band source-data conflict (hand-built uses worksheet's L; Elmhurst mapper trusts Summary's M) — surfaces as a known caveat in cross-mapper diff.
