Khalim Conn-Kowlessar a374bd075e P6.1 follow-on: use BuildingPartIdentifier enum in ml/transform + tests
Replace the string literal "Main Dwelling" / "Extension 1" comparisons
in `_building_part_aggregates` and the four affected tests with the
typed `BuildingPartIdentifier.MAIN` / `.EXTENSION_1` enum values, so
the transform is consistent with the typed domain introduced in the P6.1
cert→inputs adapter. Fixes a latent mismatch that would silently return
`main=None` if the string ever drifted.

Shared packages

Workspace packages consumed by services/*. Each package is its own Python distribution with its own pyproject.toml; services import via the workspace dependency mechanism ({ workspace = true }).

Package Purpose
domain/ Shared domain types — Property, BaselinePerformance, Plan, Scenario, EpcPropertyData, etc. No persistence, no IO, no business logic.
repos/ Persistence layer — one repo per aggregate. Owns the SQL. Depends on domain.
fetchers/ External API clients (gov EPC, Ofgem, Google Solar, etc.). Depend on domain for response shapes.
utils/ Cross-cutting infra — logging, S3, CloudWatch URL builders, SQS task helpers.

Adding a new shared package

Only when a real second consumer materialises. Don't pre-shatter (repos-epc, repos-property, ...) — split when a deployment needs to drop a dep, not before.

See ../ara_backend_design.md §11 for the broader monorepo layout and ../CONTEXT.md for the domain glossary that names the types living in domain/.
