Khalim Conn-Kowlessar b6544e1cd1 Handover: tighten Summary→SAP chain pin to 1e-4 + brief next agent ... Slice 46c left the chain at SAP Δ=0.26 vs the Elmhurst worksheet PDF's 62.2584. The user rejected the 0.5 tolerance: because the cascade reproduces Elmhurst exactly on hand-built inputs and the Summary PDF carries the same source-of-truth data, the mapped path must hit 1e-4 like every other Elmhurst worksheet pin. This commit: - Tightens `test_summary_000474_full_chain_sap_matches_worksheet_pdf_exactly` from 0.5 to 1e-4. Currently fails with Δ=0.2611 — the forcing function for the next slice. - Replaces the stale `docs/sap-spec/NEXT_AGENT_PROMPT.md` with a fresh handover identifying the two remaining diffs: * pumps_fans_kwh_per_yr 130 vs 160 (30 kWh; likely `central_heating_pump_age` not plumbed) * Window [4] mis-classified as SE (4) instead of E (3); `_compose_window_descriptors` over-joins suffix tokens - Documents the architectural smell (3-schema chain ElmhurstSiteNotes → EpcPropertyData → CalculatorInputs may be over-engineered). - Lists end-goal: API-path < 0.5 SAP (rounded integers), Elmhurst-path < 1e-4 SAP (unrounded worksheet pins), then replicate for the other 5 Summary PDFs.
