"""Window-extraction completeness pin for cert 001431.

The Modelling glazing overlay's draught-proofing recompute (RdSAP 10 §8.1 — a
count over openable windows + doors) needs every openable §11 window captured
with its `draught_proofed` flag. The Elmhurst Summary §11 block lodges 17
openable windows; two extraction gaps previously surfaced only 14:

  1. The extractor rejected the one "Double glazing, known data" row whose
     data-source cell is "BFRC data" (laid out as its own line, with no frame
     factor) — it does not fit the `<data-source> <U>` Manufacturer-line shape.
  2. The mapper's `_is_elmhurst_roof_window` reclassified the two "Double pre
     2002" rows (U 3.1 / 3.4 > 3.0) as roof windows, even though both are
     lodged on an "External wall" — a false positive of the U-value backstop.

With both closed, all 17 windows are `sap_windows` (none mis-routed to
`sap_roof_windows`), and 14 carry `draught_proofed=True` — reconstructing
Elmhurst's lodged 84% draught-proofing (16/19 = (14 windows + 2 doors) /
(17 windows + 2 doors)).
