Khalim Conn-Kowlessar 67af2e9b43 docs: handover for §8c Space cooling + 000490 SAP-score diagnostic ... Two tickets in order for the next agent: 1. Ticket A — Investigate the 000490 +3 SAP overshoot. Corrects the previous agent's claim that "wiring water_heating_from_cert is the easy win"; that's already done. Real driver is the boiler efficiency cascade selecting 0.80 instead of the PDF Manufacturer-declared 0.882 (Vaillant Ecotec Pro). Time-boxed diagnostic; flag and defer if expensive. 2. Ticket B — §8c Space cooling (xlsx rows 435-466, lines (100)..(108)). All 6 Elmhurst fixtures = 0 cooling. Small slice; mirror §8 pattern. Includes spec anchors (Qcool formula sign, Jun-Aug inclusion rule), codebase pointers, slice plan, and the standard "do not" list.
