Khalim Conn-Kowlessar 80845b0919 P5.4: SapResult.intermediate exposes HLC, HLP, τ, annual averages
heat_transfer_coefficient_w_per_k (HLC), heat_loss_parameter_w_per_m2k
(HLP), time_constant_h, and the two annual averages
(internal_gains_annual_avg_w, mean_internal_temp_annual_avg_c) populated
on `intermediate`. The averages let sweep slices verify monthly-loop
outputs without re-summing 12 months.

134 SAP tests pass.

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/.
