When a stone wall lodges no documentary thickness, RdSAP 10 §3.5 Table 3 supplies the default thickness to feed the §5.6 formula — it does NOT fall to a flat 1.7. Table 3 stone row: A-D = 500 mm, E = 450, F-H = 420; Scotland footnote (*) adds 200 mm for bands A,B and 100 mm otherwise. This matches accredited Elmhurst: an England age-B granite/whinstone wall, as built, unknown thickness defaults to 500 mm → U = 45.315 × 500^(-0.513) = 1.87 (sandstone → 1.68). The previous flat-1.7 fallback was a setup error — Table 6 reads "According to 5.6" for bands A-D with no 1.7 entry, so the formula (not 1.7) is the spec target. The age-E footnote-(a) cap still applies on top. Adds `_table_3_stone_thickness(band, country)`. Updated the stale `..._returns_table_6_age_a_default` pin (was 1.7 → now 1.87 via Table-3) and added sandstone (1.68) + Scotland-+200mm (700 mm → 1.39) pins. Corpus: within-0.5 71.6% unchanged, SAP MAE 0.821 → 0.819, PE MAE 3.7 → 3.6. pyright not installed in this container — strict type gate not run locally.
