- SPEC_COVERAGE §4 row: closed (combi-gas single-rate) — PCDB Table 3b + Eq D1 cascade. 000474 + 000490 HW kWh ≤0.1% of PDF. Remaining §4 work list refreshed: storage / FGHRS rows, Table 3c two-profile, Electric CPSU Appendix F, instant electric shower, Appendix L lighting (separate ticket per memory). - §4 slice progress table: (61)m row updated with `760e25de` commit pointer + dual sourcing (Table 3a default + PCDB Table 3b row 1 override). - test_golden_fixtures.py: SAP_TOLERANCE stays ±11 — §4 HW closure doesn't shift the oil-heated golden certs because they aren't PCDB Table-3b-listed. Comment block updated with the §4 slice 2 note. No code changes — docs + tolerance comment only. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

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/.
