Fixed the build script (explicit chimney zeroing + wall thickness set to 220mm, since `CheckBoxWallThicknessUnknown` doesn't persist via Playwright and leaving it blank makes the Walls section invalid) and a real build-script bug (`ref.input_value()` truthiness check treated the string `"0"` as truthy, causing spurious navigation to Home.aspx that broke the SpaceHeating nav). Clean rebuild: eng 53 vs Elmhurst 51 โ€” only a ~2pt gap now (was ~5-7pt). No mapper.py change was needed/made โ€” the gov-API mapper's open_chimneys_count=0 was correct all along; the register itself lodges open_fireplaces_count=0. Remaining ~2pt gap not chased further: single-window-orientation approximation (South, max solar gain) plus untriaged minor divergences.
