Khalim Conn-Kowlessar 1f271ca891 Slice 80: 1:1 windows expansion in cohort 000487 (2 → 5 entries)
Closes the final `sap_windows: LEN 5 vs 2` divergence by replacing
the cohort 000487 hand-built's 2-window collapsed encoding with 5
SapWindow entries mirroring the Summary §11 1:1. All South-facing
(orient=5) / PVC frame; two glazing-type groups; per-bp totals
preserved (cascade-equivalent):

  g=0.76/U=2.8: 0.77 m² (Ext1) — unchanged
  g=0.72/U=1.4: 6.69 m² total split per-bp
    Main: 1.65 m² (1 row)
    Ext1: 5.04 m² split 2.16 + 1.53 + 1.35 (3 rows)

Mapper places the Main window between two Ext1 rows in the §11 table;
the hand-built mirrors that order so list-position diffs are zero.

Cascade output unchanged: all 11 `_FIXTURE_PINS["000487"]` SapResult
pins remain GREEN at 1e-4 against worksheet `SAP value 61.6431`.

**Cohort 000487 is now fully Layer-2 GREEN** —
`test_from_elmhurst_site_notes_matches_hand_built_000487` passes with
zero load-bearing divergences between the mapped EpcPropertyData and
the hand-built fixture.

Full sweep: 105 passed (was 104 pre-Slice-77; +1 new diff test), 10
failed (same 10 001479-related). Pyright net-zero.

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/.
