When the main heating is electric storage / direct-electric (codes
191-196, 401-409, 421-425), the cert almost always carries an
Economy-7 tariff and the immersion HW cylinder runs on the off-peak
timer. Bill HW at the 7h-low rate (5.5 p/kWh) in that case, falling
back to the lower of {7h-low, water_heating_fuel rate} so we never
over-charge an HW fuel that's already cheaper than off-peak.
100-cert parity probe:
MAE 4.90 → 4.66 (-0.24)
bias -1.44 → -0.70 (over-correction halved)
within ±3: 46% → 48%
within ±5: 67% → 68%
within ±10: 93% → 94%

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.
