End-to-end §3 fabric heat loss now matches the Elmhurst worksheet to
0.1 W/K (the worksheet displays per-element U-values to 2 d.p.; our
cascade keeps full precision so the totals differ at the third decimal).
Cert inputs lodged on the fixture:
- roof_insulation_thickness=300 mm on Main and Ext1 → Table 16 U=0.14
- door_count=2 (cascade default 1.85 m²/door → 3.70 m² worksheet area)
- WINDOW_TOTAL_AREA_M2=9.03 with WINDOW_AVG_RAW_U_VALUE=2.8 (pre-2002
double-glazed PVC, 12mm gap; Table 24 row → U_eff=2.518)
Per-part window/door apportionment cancels in the §3 line totals — net
wall sums to the same value whether openings sit on Main or Ext1 — so a
single aggregate area/U pair reproduces (33) exactly.

domna-domain
Shared domain types — Property, Properties, BaselinePerformance, Plan, PlanPhase, Scenario, ScenarioPhase, ScenarioSnapshot, Recommendation, OptimisedPackage, EpcPropertyData, etc.
Boundary: types only. No persistence, no IO, no business logic. Other packages and services depend on domna-domain; this package depends on nothing internal.
Domain definitions live in ../../CONTEXT.md. New types added here must match the glossary terms.
