Khalim Conn-Kowlessar 5324ae0e57 PasHub floor exposure + alternative walls + extension floor 🟩
Resolve #1601 and land #1602/#1603 on the merged-#1609 tree, adjudicated
against Khalim's verified ground truth (not pre_sap).

#1601 (upper-floor +0.25 m joist void) — RESOLVED as keep-raw. The
gov-API/Elmhurst mappers add 0.25 m to upper-storey heights because their
lodged height is a clear internal ceiling. Against verified truth RAW beats
+0.25 on all 7 verified dwellings (16 Stillwater raw -0.35 within-band vs
+0.25 -0.75; every verified property is already under truth and +0.25 only
lowers SAP). pashub surveys internal dimensions (202/205 "Measurements
Location: Internal") and its upper-ground height gap is modal 0.00, so the
joist void is not differentially present and a blanket +0.25 is unsafe.
_map_floor_dimensions keeps the raw surveyed height with a RESOLVED note.

#1602 — semi-exposed / exposed floor exposure. The surveyed "Floor type"
"Semi Exposed (unheated)" now sets is_above_partially_heated_space (RdSAP
§5.14 U=0.7) and "Exposed Floor" sets is_exposed_floor (§5.13 Table 20), on
the lowest storey (floor==0) only, mirroring the gov-API/Elmhurst siblings.
New strict-raise _pashub_floor_exposure (ADR-0015).

#1603a — alternative walls. New AlternativeWall survey dataclass +
extract_alternative_walls (the "Alternative Wall"->"Windows" section) +
_map_pashub_alternative_walls -> sap_alternative_wall_1/2. The cascade
deducts each alt-wall area from the part's main opaque wall (no double
count), so a mixed-facade dwelling is billed at each sub-area's own
construction. The alt-wall block lodges "As Built" (capital B) — aliased to
the existing default insulation code.

#1603b — extension floor construction. ExtensionConstruction gains a floor
block (parsed like the main building) and _map_extension_building_part now
threads floor_type/construction/insulation/u_value_known, which the main
path already did and the extension silently dropped.

Cohort: within-0.5 50.2% -> 51.2%, MAE 0.652 -> 0.624, 0 strict-raise
errors across all 205. Verified-truth safe: none of the 7 verified
dwellings have alt walls, and #1602 moves the one it touches (2 Philips
exposed ext floor) by -0.00. pyright 0-new (mapper baseline 39). Goldens
test_full_building_construction + end_to_end EXTENSION_1 updated.
