Jun-te Kim 8e487a9bae docs(elmhurst): validate slice-5 wall fix against accredited Elmhurst worksheet (uprn 200004296092) ... Built the cert in accredited Elmhurst RdSAP10-Online on the lodged register inputs; downloaded Input Summary + SAP Worksheets (committed alongside). Confirmed: - Slice 5 DIRECTION validated: the externally-insulated solid-brick wall is billed insulated by both tools (Elmhurst U 0.48, engine U 0.29), far below the uninsulated 1.40 the pre-fix §5.8 gate produced. - ROOF matches EXACTLY (U 0.30, 9.35 W/K). - Engine 71.74 = lodged 71; Elmhurst current SAP 66 (its "unknown external insulation" default is more conservative + this build used a generic combi and no keyed wall thickness, so 66 is not a clean engine-comparison). Follow-up lead (documented in ELMHURST_FINDINGS.md): the engine feeds the UNMEASURED lodged wall_thickness (360 mm, measured=N) into the §5.6 formula, whereas RdSAP §5.3 uses measured thickness / Table-3 default otherwise. The party-wall "difference" is NOT a bug (engine 0.25 is spec-correct, Table 15 row 4). Also adds the build script scripts/hyde/build_200004296092.py. No engine change in this commit.
