Khalim Conn-Kowlessar 6baf66cdde Slice 68: party-wall "U Unable" + central_heating_pump_age_str → 1 diff left ... Closes 4 of 5 remaining cohort 000474 diffs (5 → 1): **Mapper:** Add "U" → 0 to `_ELMHURST_PARTY_WALL_CODE_TO_SAP10`. The modal cohort lodgement Summary §7 "Party Wall Type: U Unable to determine" was previously falling through to None; the cohort hand- built convention uses 0 as the explicit "unknown" sentinel. The cascade resolves both 0 and None to the same `u_party_wall` default (0.25), so cascade output is unchanged. Closes 3 diffs (one per bp). **Hand-built:** Set `central_heating_pump_age_str="Unknown"` on cohort 000474 Main heating detail (post-construction since the helper doesn't expose the kwarg). Matches the Elmhurst mapper's surfaced value from Summary §14 "Heat pump age: Unknown" — the str dual- encoding internal_gains.py reads. Closes 1 diff. All 66 cohort cascade pins remain GREEN at 1e-4. Pyright 35-error baseline preserved on mapper.py; 0 errors on the hand-built file. Remaining 1 diff on cohort 000474: - `sap_windows: LEN 7 vs 5` — the cohort hand-built collapsed §11 by glazing-type × orientation × bp group (preserving total area, cascade-equivalent but not field-equal); the mapper extracts 1:1 with the worksheet's 7 §11 table rows. Next slice will expand the hand-built to 7 individual SapWindow entries matching the mapper. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-25 17:02:04 +00:00
