"""Elmhurst build for UPRN 100021924710 (RdSAP-21.0.1, MID-TERRACE HOUSE, band B,
SOLID BRICK 250 mm uninsulated, pitched insulated (assumed) loft, floor to
UNHEATED space, mains-gas COMBI (PCDB 19008) + gas room-heater SECONDARY, DUAL
meter, 11 DG windows ~18.32 m², TFA 116. Lodged SAP 63; engine 65.0 (Δ +2.0).

Per-cert Elmhurst validation. Uses set_single_window (deletes the shared
assessment's carried-over window rows) + reset_transient_state at the end so the
assessment is left neutral. Run:
