Khalim Conn-Kowlessar 7f099d986a Slice S0380.13: widen cantilever gate to accept "House" descriptive form ... Closes cert 2636 to spec floor (Δ +0.5167 → +0.0323) by accepting both the EPC schema enum-as-string ("0") AND the Elmhurst Summary mapper's descriptive form ("House") for the cantilever-detection property-type gate at `heat_transmission.py:768`. Root cause: slice 102f-prep.9 (commit 06b4ef3d) added cantilever detection gated on `epc.property_type == _PROPERTY_TYPE_HOUSE` where `_PROPERTY_TYPE_HOUSE = "0"`. That matches the API mapper's encoding (schema enum), but the Summary mapper produces "House" (descriptive) and the hand-built worksheet fixtures also use "House" — so neither triggers the gate and the cantilever path silently no-ops on the Summary path. Cert 2636's worksheet (28b) "Exposed floor Main 3.74 × 1.20 = 4.4880" is the cantilever — without surfacing it the cascade missed 4.488 W/K of floor heat loss. Three-encoding origins: - API mapper: property_type='0' (schema enum-as-string) - Summary mapper: property_type='House' (descriptive from §1) - Hand-built fixtures: property_type='House' (legacy convention) Fix: replace the equality check with a `_is_house()` helper that accepts the {"0", "House"} frozenset. Centralised so future property-type sensitive gates can call the same helper. Forcing function: cert 2636 first-attempt Summary SAP closes from Δ +0.5167 (after S0380.12 walls fix) to Δ **+0.0323** — within the ±0.07 ASHP-cohort spec floor. `floor_w_per_k` moves from 19.1982 (ground floor only) to 23.6862 (ground 19.20 + cantilever 4.49 = worksheet (28a) + (28b) exact match). Cohort closure status (6 of 7 ASHP certs at spec floor): cert Δ vs worksheet spec floor? 0380 +0.0594 ✓ 0350 +0.0458 ✓ 2225 +0.0441 ✓ 2636 +0.0323 ✓ ← this slice 3800 +0.0442 ✓ 9285 +0.0502 ✓ 9418 +2.5973 ✗ (Daikin EDLQ05CAV3 — final cert) Boiler hand-built parity verified intact: 5 hand-built cohort certs (000474, 000477, 000480, 000490, 000516) all use property_type= "House" and now also fire the cantilever gate, but none have floor1_area > floor0_area + 1m² (the cantilever-area trigger) so their cascade output is unchanged. Regression suite 683 pass + 10 fail (= handover baseline 669 + 10 + 17 new GREEN tests across S0380.2..S0380.13).
