Khalim Conn-Kowlessar 3ac07bd04a Slice 37: sap_ventilation mapper fix (21.0.1) + per-cert golden pin ... The 21.0.1 mapper produced EpcPropertyData with sap_ventilation=None, so the cert→inputs cascade defaulted every ventilation count to zero even when the cert lodged extract fans (most schema-21 certs do). extract_fans_count was double-mapped — surfaced as a top-level field the calculator never reads, but missing from the SapVentilation slice the cascade does read. Fix: populate sap_ventilation in from_rdsap_schema_21_0_1 with extract_fans_count. Drives ~⅓ of the rating-cohort drift on a clean no-PV no-secondary gas-combi cert. Refactored test_golden_fixtures.py from global tolerance ceilings (±13 SAP / ±35 PE) to per-cert pinned residuals at abs SAP=0, PE=0.01 kWh/m², CO2=0.001 t/yr. Each cert's _GoldenExpectation now records the actual current residual (SAP/PE/CO2 — CO2 newly pinned via the postcode-cascade environmental section). Drift in either direction fires the test: tighten the pin on improvement, document on regression. Recorded residuals reflect known remaining mapper gaps (RR room-in- roof extraction on cert 0240, oil cascade on 0390, etc.) — tracked in each cert's notes: field, not acceptance bounds. 930/930 Elmhurst cascade pins unchanged (site-notes EPCs already populate sap_ventilation). 257/257 mapper tests green. 10/10 golden cohort green under the new pins. Pyright net-zero (34 errors before and after). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-24 11:30:12 +00:00
