# 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`](../../CONTEXT.md). New types added here must match the glossary terms.

When `datatypes/epc/domain/` folds in, the EPC schema types move under `src/domain/epc/`.
