Make the stored units explicit on the property_baseline_performance columns: - `*_co2_emissions` → `*_co2_emissions_t_per_yr` (tonnes CO₂/yr, whole dwelling) - `*_primary_energy_intensity` → `*_primary_energy_intensity_kwh_per_m2_yr` Column names only; the domain `Performance` VO stays unit-suffix-free (units are a storage concern, mapped in from_domain/to_domain). Migration doc updated. Round-trip stays green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
