Khalim Conn-Kowlessar dae2a6f3fe slice S-B16: RdSAP energy_tariff enum verified (1=dual, 2=Single, 3=Unknown)
Confirmed against the official RdSAP enum in
datatypes/epc/domain/epc_codes.csv:
  1 = dual                  (off-peak / Economy-7)
  2 = Single                (standard tariff)
  3 = Unknown               (verified against Elmhurst assessor software:
                             treated as Single)
  4 = dual (24 hour)        (off-peak)
  5 = off-peak 18 hour      (off-peak)

Different from the SAP-Schema enum (1=standard / 2=off-peak) — the
transform.py docstring referenced the SAP enum, not RdSAP. Our corpus
is RdSAP so we use the RdSAP codes.

This locks in the meter_type-based tariff selection from S-B15 with
the authoritative enum, replacing the earlier heating-code heuristic.

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.
