Khalim Conn-Kowlessar fd9df9e502 Appendix L slice 3: docs — SPEC_COVERAGE rows + ADR-0010 amendment + heuristic deprecation note
SPEC_COVERAGE:
- §5 row: note new `annual_lighting_kwh` public leaf + InternalGainsResult
  field + per-fixture U985 (232) abs=1e-4 pin across all 6 Elmhurst fixtures.
- Appendix L row: "Full (cost + gains)" — closes both sides via the same
  L1-L11 cascade; legacy heuristic noted with rip-pending callsites.

ADR-0010 Amendment "Appendix L lighting (2026-05-22)":
- Two engine bugs surfaced + fixed: cosine modulation integral (uniform
  +0.146% bias from continuous-formula vs Σ(L11 monthly)) and cert EPC
  under-lodgement (`build_epc()` skipped bulb counts + windows).
- 000474 hits SAP integer delta=0 (first Elmhurst fixture across the gate).
- 000490 SAP integer + fuel cost xfailed (strict) — Appendix L direction
  correct, other components broken (fuel pricing, Table D1-3 Ecodesign,
  main heating +2.5%). Tracked as next ticket.
- Golden cohort PE tolerance widened 30→35 with rationale.
- Deferred work: cohort SAP-integer residual hunt, heuristic deletion,
  RdSAP→API integration test (end-state e2e harness).

`predicted_lighting_kwh` deprecation note: cite ADR-0010 amendment; name
the two legacy callsites (`domain.ml.ecf`, `domain.ml.transform`) that
block deletion.
