Khalim Conn-Kowlessar 6bfb0614aa Slice 19a: strict cascade-pin scoreboard for SapResult vs U985 PDFs
Replaces the loose collection of fixture-specific SAP score tests +
parametrized lighting / pumps_fans / secondary spot-checks with a
single strict cascade pin: every SapResult float field vs PDF line
ref at abs=1e-4, every fixture × field pair as its own parametrized
case. 66 cases (11 fields × 6 fixtures); 18 pass, 48 fail.

Why: the Elmhurst corpus is a deterministic test-vector set — input
lodgement, intermediate values per line ref, final SAP outputs all
known to 4 d.p. To replicate SAP 10.2 exactly there is no reason to
accept tolerance >0 on the final outputs. The prior pattern (per-
section unit tests using PDF values as INPUTS, fixture-specific SAP
tests at <=0.5 continuous, fuel-cost tests at rel=0.05 / rel=0.15)
let cascade biases propagate without surfacing as named failures.

Pin matrix:

Each failing test name is the work queue. No tolerance widening, no
xfail — a failing pin is a named calculator bug. Subsequent slices
close them one at a time.

Existing loose-tolerance tests in test_fuel_cost.py (rel=0.15 for
000474 and rel=0.05 for 000490) are subsumed by the new
total_fuel_cost_gbp pin at abs=1e-4 and will be removed in 19b.

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.
