History
Khalim Conn-Kowlessar 74b2c1131f §4 conformance: extend Elmhurst fixtures to 6/6 across (42)..(65) 
Populates §4 LINE_42..LINE_65 + per-fixture HW inputs (HAS_BATH,
MIXER_SHOWER_FLOW_RATES_L_PER_MIN, COLD_WATER_TEMPS_C, LOW_WATER_USE,
COMBI_LOSS_OVERRIDE, ELECTRIC_SHOWER_OVERRIDE) in 000477, 000480,
000487, 000516 — values extracted from the Elmhurst U985 worksheets
supplied 2026-05-20. 000474 + 000490 get the same input constants for
uniform parametrization.

Adds electric_shower_monthly_kwh_override to water_heating_from_cert
to unlock 000487 (instantaneous electric shower, no mixer). The
orchestrator's has_shower flag now also accounts for the electric path.

Extends 6 parametrized §4 tests from (000474, 000490) to ALL_FIXTURES
and adds a new ALL_FIXTURES-parametrized e2e test exercising the
orchestrator end-to-end through (42)..(65) for every Elmhurst fixture.
Tolerance on (43)/(44) loosened to 5e-3 to absorb Elmhurst's 4-d.p.
display rounding.

Result: 150/150 tests pass; §1-§4 conform at ≤1e-2 kWh / 5e-3 L for
every fixture. Deferred branches surfaced via overrides:
- PCDB Table 3b combi loss (000474, 000477, 000516)
- Non-time-clock Table 3a combi loss rows (000480, 000487)
- Electric-shower (64a)m derivation from cert codes (000487)

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.
