"""Elmhurst build for UPRN 100031768368 (RdSAP-21.0.1, END-TERRACE HOUSE, band C,
SOLID BRICK 280 mm uninsulated, pitched 100 mm loft insulation, SOLID ground
floor uninsulated, mains-gas COMBI (PCDB 18250, Baxi 630 Combi 88.4%) +
gas ROOM-HEATER SECONDARY, single electric shower with WWHRS (no mixer
shower), extract fan lodged (1) + 1 other-heater flue, 10 DG windows across
2 orientations (~13.48 m2 total: East 5.52 m2, West 5.13+2.83 m2 across two
glazing eras), TFA 76. Lodged SAP 61; engine 59.12 (Delta -1.88).

Per-cert Elmhurst validation, continuing the 1-2 SAP-band reconciliation
pass. Uses set_window_groups (3 orientation/glazing groups, not a single
collapsed window — see the 100061275133 finding that a single-orientation
simplification meaningfully understates solar gain) + reset_transient_state
at the end so the shared assessment is left neutral. Run:
