Add the Ara modelling aggregate root (ADR-0002): domain/property/ with PropertyIdentity, SiteNotes, Property, Properties. Property.source_path implements the two disjoint source paths + Recency Tie-Break (ADR-0001; survey wins on an equal date); effective_epc resolves to the surveyed data (Site Notes path) or the public EPC (epc_with_overlay path — Landlord Overrides overlay is a later slice). Pure dataclasses, no infrastructure imports. PropertyRepository port + PropertyPostgresRepository hydrate the aggregate whole from a defensive view of the FE-owned 'property' table (identity columns) plus the EPC slice via EpcRepository.get_for_property. Reads only from repos (ADR-0003). 8 domain + 1 hydration test; pyright strict clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
