Khalim Conn-Kowlessar d44af109a9 Docs: SAP calculator module README + API integration test handover ... The SAP 10.2 / RdSAP 10 calculator is closed at 930/930 pin tests green. Tidying the docs for hand-off to the API-integration agent. New: docs/sap-spec/SAP_CALCULATOR.md Canonical module overview — public API surface, two-cascade architecture (Rating UK-avg, Demand postcode), simulator-use-case example, file map, validation contract + hard rules, fixture cohort notes, spec page references. Replaces the scattered "what's the shape" knowledge that was previously only in commit messages. Rewritten: docs/sap-spec/HANDOVER_NEXT.md Old handover (work queue for slices 26-36) is obsolete. Replaced with the next agent's brief: build an API → SAP scoring integration test using the 6 Elmhurst fixtures. Includes a copy-paste reference scoring path, expected outputs per fixture, list of files to read on day 1, and scope guardrails. Refreshed module docstrings: - cert_to_inputs.py: now describes both cascades, the deferred-edge- case list reflects current state (RR/secondary/§15 living-area rounding all DONE; thermal-mass and control-temp adjustment still deferred). - calculator.py: per-end-use CO2/PE factor machinery documented; stale "single-fuel approximation" claim removed (closed in slice 32). - sap/README.md: validation paragraph now says "930/930 green" and points to SAP_CALCULATOR.md instead of the obsolete HANDOVER_NEXT. Verified the API examples in both docs produce the expected per-fixture outputs (SAP=62, EI=60, Carbon=3104.1222, PE=16931.7227 for 000474). Wider regression: 1585/1585 PASS, zero failures.
