Khalim Conn-Kowlessar ebceb4bf2b slice 12: ventilation flat features
Four ventilation features: mechanical_ventilation (categorical
SAP10 code, 0=natural through 6=positive-input-from-outside per
epc_codes.csv mechanical_ventilation enum), mechanical_vent_duct_type
(categorical), blocked_chimneys_count (int), and pressure_test
(int — air-tightness SAP10 code).

Pulled from top-level EpcPropertyData fields; ventilation on SAP10
API EPCs sits on the certificate directly, not on the
sap_ventilation block (which is site-notes-only).

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.
