Khalim Conn-Kowlessar c5aa5620ca fix(uvalues): apply §5.8 insulation R to stone walls (RdSAP 10 p.41-42)
The §5.8 Table-14 added-insulation R-value adjustment was gated to
WALL_SOLID_BRICK, so a stone (granite/sandstone) wall lodging
wall_insulation_type 1/3 ("External"/"Internal") + a thickness fell
through the §5.6 thin-wall branch and was billed at its UNINSULATED U
(e.g. sandstone 520 mm + 100 mm internal: 1.64 instead of 0.30 → ~5×
the wall heat loss). Mirror the brick insulation branch into the stone
block, feeding the RAW §5.6 U₀ into the §5.8 chain per the same rule the
brick branch and the dry-lined granite pin 000565 already follow (the
Table-6 footnote (a) 1.7 cap does not apply on the insulated path).

Corpus cert 100052159386 (sandstone 520 mm + 100 mm internal): -26.20 ->
-4.08 SAP, walls 300 -> 55 W/K. RdSAP-21.0.1 corpus within-0.5 68.6% ->
68.8% (SAP MAE 0.942 -> 0.888; PE MAE 14.3 -> 13.9; CO2 0.27 -> 0.26);
floors/ceilings ratcheted. Unit-pinned in test_rdsap_uvalues.
