Khalim Conn-Kowlessar 42ed6f8e46 Persist the explicit basement-wall determination 🟩
RdSAP 10 §5.17 / Table 23. `wall_is_basement` is not a lodged U-value — it is a
disambiguation flag selecting WHICH RdSAP default applies, so unlike
wall/roof/floor_u_value it must survive the round-trip.

Code 6 is canonically SYSTEM-BUILT and the gov-API path infers "basement" from a
code-6 heuristic; the Elmhurst site-notes mapper sets wall_is_basement=False
precisely to defeat it. Dropping the field inverted the answer — a system-built
wall came back as a basement wall, dragging the whole ground floor onto the
Table 23 basement-floor U-value via `has_basement`.

Declared on no RdSAP schema, so it never arrives via the gov API; the earlier
corpus scan showing 0 occurrences measured the wrong population. The Elmhurst
site-notes path sets it and those EPCs are persisted
(scripts/wchg_elmhurst_ingest.py).

Nullable is load-bearing: None = "not stated, use the heuristic", False =
"explicitly system-built, do not".
