SapAlternativeWall.u_value (heat_transmission.py:1616), .wall_thickness_mm
(:1645) and .is_basement (:1618) were read by the calculator but had no column,
so they dropped on save. Latent today (0 gov-API certs lodge them — live only on
the Elmhurst/site-notes path), but is_basement is the nastiest shape: it does not
null out, it FLIPS meaning (True -> None -> is_basement_wall reads False),
silently switching off the RdSAP §5.17 / Table 23 basement-wall U path.
Add alt_wall_{1,2}_{u_value,thickness_mm,is_basement} to EpcBuildingPartModel,
write in from_domain, reconstruct in _to_alt_wall, and drop the three
_UNPERSISTED_ALLOWLIST entries so the structural guard enforces them. is_basement
is nullable (None "not stated" != False "not a basement"; a NOT NULL DEFAULT
false re-enables the code-6 heuristic — same reasoning as #1661's wall_is_basement).
Companion assessment-model migration: six nullable columns on epc_building_part
(deploy gate). Round-trip + field-coverage guard green.
