Khalim Conn-Kowlessar 13719e010a Slice 28: §8c + §8f cascade pins (48/48)
Adds `space_cooling_section_from_cert(epc)` and
`fabric_energy_efficiency_from_cert(epc)` to the cert→inputs cascade.

§8c (lines 100..108) — all 6 Elmhurst fixtures have
`has_fixed_air_conditioning=False` so f_C=0 collapses (107)/(108) to
zero, (101) η_loss=1 for every month (γ=0 branch), (103) gains=0, and
(106) intermittency follows the spec Jun-Aug mask 0.25. (100), (102),
(104) depend on H × (24 − T_e) per fixture and are not asserted in the
cascade (covered by `test_space_cooling.py` synthetic-positive case).
42/42 §8c pins PASS.

§8f (line 109) — Fabric Energy Efficiency = (98a)/(4) + (108). For all
6 fixtures (98b) solar space heating = 0 and (108) = 0, so (109) = (99)
exactly. 6/6 §8f pins PASS.

Cascade scoreboard: 348/348 → 396/396 (§7..§8f closed).

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.
