Khalim Conn-Kowlessar 54cc9bd3ba Appendix L slice 2: cert→cascade lighting kWh + 000474 e2e closes to delta=0 Closes the +9.2% cost residual on 000474 by swapping the legacy `predicted_lighting_kwh` heuristic (9.3 × TFA × bulb-share) for the spec-faithful Appendix L L1-L11 cascade that already drove §5 (67) internal gains. Single source of truth via `InternalGainsResult. lighting_kwh_per_yr`; the cost side and the gains side now derive from the same monthly distribution. Engine bug found during the wire-up: `annual_lighting_kwh` was returning the L1-L9 continuous formula value (E_L), but the SAP10.2 worksheet lodges line ref (232) as Σ(L11 monthly distribution). Discrete cosine integral Σ(n_m × factor) / 365 = 0.998539, not 1.0 exactly — caused a uniform +0.146% bias across all 6 Elmhurst fixtures. Fixed by factoring a private `_lighting_monthly_kwh` and having `annual_lighting_kwh` sum it directly. Synthetic S1 pin updated 189.152079 → 188.875713 (post-modulation). Cert-side updates: lodge `low_energy_fixed_lighting_bulbs_count` + `sap_windows` on 000474 / 000490 `build_epc()` so the cert→cascade path receives spec-faithful inputs (was defaulting to L5b/L8c + C_daylight=1.433 no-bonus). Per-fixture `LINE_232_LIGHTING_KWH_PER_YR` constants pin each U985 PDF value at 4 d.p. E2E pin updates (per feedback-e2e-validation-philosophy: components validate the engine; SAP integer = delta 0 is the integration gate): - 000474 SAP integer ceiling tightened 3 → 0 (lands at 62 = PDF 62 exactly); continuous 3.5 → 0.5 (lands at 0.09) - 000490 SAP integer + fuel-cost tests xfail with rationale — Appendix L direction is correct (lighting closes 614→171 = PDF 171.4217), but cost residual widens past 5% / SAP delta widens 3→6 due to other broken components (fuel pricing, Table D1-3 Ecodesign, main heating +2.5%). Re-enable when those close. - Golden fixtures `_PE_TOLERANCE_KWH_PER_M2` widened 30 → 35 to absorb the elec-PEF × lighting-Δ contribution (~4 kWh/m²) on a non-Elmhurst cohort whose pre-existing residual already sat near -28 kWh/m² from unrelated components. Component validation: `result.lighting_kwh_per_yr == PDF (232)` to abs=1e-4 for 000474 (139.9452) + 000490 (171.4217); §5 worksheet- level pin on `InternalGainsResult.lighting_kwh_per_yr` covers all 6 Elmhurst fixtures at the same tolerance. Existing §5 (67) LINE_67 monthly tuple tests remain green (refactor preserves monthly W distribution). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-22 09:15:22 +00:00

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.
