Stage 2 of First Run. Establishes each Property's Baseline Performance from persisted source data and writes it back — reads only from repos, never a Fetcher or HTTP (ADR-0003), so it is byte-identical whether Ingestion ran milliseconds ago or last week. Domain (`domain/baseline/`): - `Performance` VO — the four rated quantities: SAP / EPC Band / CO2 / Primary Energy Intensity. `lodged_performance(epc)` reads them off the EPC's recorded fields (PEUI = `energy_consumption_current`). - `BaselinePerformance` (ADR-0004) — the paired `lodged` + `effective` Performance + `rebaseline_reason`, plus the no-derivation part of the energy block (`space_heating_kwh` / `water_heating_kwh`, off the RHI, deterministic per ADR-0006). Both halves always populated. - `Rebaseliner` port + `StubRebaseliner`: the re-score-on-override seam (ADR-0011). SAP10 certs pass through (effective == lodged, reason "none"); a pre-SAP10 cert raises `RebaselineNotImplemented` rather than fabricating a plausible-but-wrong "none" — ML rebaselining is not wired yet. Mirrors the repo's strict-raise culture. Persistence: new `BaselineRepository` port + `BaselinePostgresRepository` + flat-column `baseline_performance` SQLModel (one row per Property). Per ADR-0004's amendment this is a standalone table, NOT columns on the retiring `property_details_epc`. Production migration is FE-owned (Drizzle) — docs/migrations/baseline-performance-table.md. Docs (grill-with-docs): corrected CONTEXT.md Lodged/Effective Performance to Primary Energy Intensity (the term collided with its own _Avoid_ entry under "heat demand") + fixed stale RHI field names; amended ADR-0004 Consequences for the standalone-table decision. Fuel split + bills (rest of EPC Energy Derivation) deferred to a follow-up — they need a Fuel Rates source (Ofgem-cap ETL) that does not exist yet. TDD, one test -> one impl: 7 tests (lodged read, rebaseliner pass-through + raise, orchestrator establish-and-persist + pre-SAP10 raise, Postgres round-trip + absent). pyright strict clean; AAA layout.

baseline_performance table — FE-owned migration
Context: Slice 6 (Hestia-Homes/Model#1135) of the ara_first_run rebuild. The
BaselineOrchestrator establishes a Property's Baseline Performance (ADR-0004) and persists it
via a new BaselineRepository port. This is a brand-new table — no predecessor.
Per ADR-0004's amendment, the lodged/effective pair does not land on property_details_epc
(which is being retired as too coupled to the legacy EPC-API schema). It lands here, as its own
aggregate's table.
The SQLModel row is defined in infrastructure/postgres/ so the ephemeral-Postgres tests build it
via SQLModel.metadata.create_all. The production migration is FE-owned (Drizzle ORM) — a
straight lift-and-shift of the columns below.
baseline_performance — one row per Property
| Column | Type | Notes |
|---|---|---|
id |
serial PK | |
property_id |
int, FK → property.id, unique |
one Baseline Performance per Property |
lodged_sap_score |
int | Lodged Performance — gov register, off the Effective EPC |
lodged_epc_band |
text | the Epc enum, stored as its string value (e.g. "C") |
lodged_co2_emissions |
float | |
lodged_primary_energy_intensity |
int | PEUI (kWh/m²/yr); not "heat demand" — see CONTEXT.md |
effective_sap_score |
int | Effective Performance — what modelling scored against |
effective_epc_band |
text | |
effective_co2_emissions |
float | |
effective_primary_energy_intensity |
int | |
rebaseline_reason |
text | none | pre_sap10 | physical_state_changed | both |
space_heating_kwh |
float | off renewable_heat_incentive; deterministic (ADR-0006) |
water_heating_kwh |
float | off renewable_heat_incentive |
This slice has no ML rebaselining, so effective_* == lodged_* and rebaseline_reason = 'none'
for every row written (a pre-SAP10 cert raises rather than persisting a wrong-but-plausible row —
see #1135). The effective_* columns exist now so the table shape is stable when ML lands.
Deferred (follow-up — EPC Energy Derivation + Fuel Rates)
fuel_split and bills are not in this table yet. They are produced by
EpcEnergyDerivationService, which needs a current Fuel Rates source (Ofgem-cap ETL) that does
not exist yet. They land together in the follow-up so this table is not migrated twice. Likely
shape: a bills-style block (per-fuel kWh + standing charge + SEG) — to be specified in that
slice's migration note.
