Khalim Conn-Kowlessar a243055de7 slice S-A7b: RdSAP cert→inputs mapper + Sap10Calculator.calculate(epc) 
Adds domain.sap.rdsap.cert_to_inputs.cert_to_inputs(epc) which produces a
typed CalculatorInputs from an EpcPropertyData, and a thin
Sap10Calculator.calculate(epc) entry point that wraps the mapper + the
S-A7a orchestrator. Defaults follow RdSAP 10 (Table 27 for living-area
fraction, Table 5 for ventilation, Table 12 for fuel cost + CO2 factor)
and SAP 10.3 Tables 4a/4b for heating efficiency via the existing
domain.ml.sap_efficiencies cascade.

Deferred to Session B: conservatory modes, room-in-roof, secondary
heating split (Table 11), multi-fuel weighted cost, thermal-mass
parameter from construction type, control-temp adjustment from
main_heating_control code.

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/.
