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.
