Khalim Conn-Kowlessar 8ac548ca2a Audit: pin u_floor §5.12 formula cascade for cert 0240 cohort geometry ... Floor U is formula-driven (BS EN ISO 13370 + RdSAP10 §5.12), not a table lookup, so cohort pins assert per-geometry values derived by hand from the spec formula. Cert 0240's main + extension building parts cover both the dt < B and dt > B branches of the solid-floor cascade with age J → Table 19 default 75 mm insulation. Hand-derivation matches calculator output to 2 d.p.; the formula cascade is correct on this cohort case. Suspended-floor + Table 19 footnote (2) overrides remain unpinned until cohort coverage demands them. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-24 17:20:01 +00:00
