Khalim Conn-Kowlessar 2d3355ee48 Slice 86: 1:1 windows expansion in cohort 000516 (2 → 5 entries)
Closes the final `sap_windows: LEN 5 vs 2` divergence by replacing
the cohort 000516 hand-built's 2-window collapsed encoding with 5
SapWindow entries mirroring the Summary §11 1:1. Single-bp dwelling;
single glazing-type group (PVC double / g⊥=0.76 / U=2.8); per-
orientation totals preserved:

  NE (orient=2): 3.88 m² split 2.15 + 1.73 (2 rows)
  SW (orient=6): 4.43 m² split 1.94 + 1.67 + 0.82 (3 rows)

Mapper interleaves NE/SW rows; hand-built mirrors that order so
list-position diffs are zero.

Cascade output unchanged: all 11 `_FIXTURE_PINS["000516"]` SapResult
pins remain GREEN at 1e-4 against worksheet `SAP value 62.7937`.

**Cohort 000516 is now fully Layer-2 GREEN.**

**All 6 cohort certs (000474, 000477, 000480, 000487, 000490, 000516)
are now Layer-2 zero-diff** — the mapper produces a load-bearing-
field-equivalent EpcPropertyData for every cohort cert. This clears
the way for closing cert 001479 (the load-bearing API↔Elmhurst
parity-test fixture; Slice 62 skeleton at 2/11 cascade pins green,
gap −3.02 SAP) and then adding the API mapper diff test (Layer 3)
and the production acceptance test (Layer 4 — ±0.5 of published SAP
69 for cert 0535-9020-6509-0821-6222).

Full sweep: 107 passed (was 105 pre-Slice-84; +2 new diff tests for
000490 + 000516), 10 failed (same 10 001479-related). Pyright net-
zero on every touched fixture across Slices 71–86.

domna-domain

Shared domain types — Property, Properties, BaselinePerformance, Plan, PlanPhase, Scenario, ScenarioPhase, ScenarioSnapshot, Recommendation, OptimisedPackage, EpcPropertyData, etc.

Boundary: types only. No persistence, no IO, no business logic. Other packages and services depend on domna-domain; this package depends on nothing internal.

Domain definitions live in ../../CONTEXT.md. New types added here must match the glossary terms.
