Extracts `water_heating_section_from_cert(epc) -> WaterHeatingResult`
helper to expose the full §4 cascade output for tests (mirrors the
existing private `_water_heating_worksheet_and_gains`, drops unused
args).
§4 pins at abs=1e-4:
scalar (2 line refs × 6 = 12): (42) occupancy, (43) annual avg L/day
monthly (7 line refs × 6 × 12 months = 504 assertions across 42
parametrized cases): (44)m daily, (45)m energy content,
(46)m distribution loss, (61)m combi loss, (62)m total demand,
(64)m output, (65)m heat gains
Per-fixture results:
000474: 9/9 PASS ✓
000477: 5/9 — combi loss (61)m diverges → cascades to
62/64/65 monthly
000480: 9/9 PASS ✓
000487: 1/9 — LINE_43 + every monthly fails (HW lodgement
defect: number_baths=1 but PDF arithmetic
suggests different shower/bath profile)
000490: 9/9 PASS ✓
000516: 9/9 PASS ✓
4/6 fixtures close §4 fully — strong cascade floor. The 000477 combi
loss residual is a specific Table 3c sub-row issue; the 000487 §4 gap
is part of its broader cert lodgement defect (RR + HW lodgement).
Cumulative scoreboard:
§1: 12 PASS / 0 FAIL
§2: 96 PASS / 0 FAIL
§3: 1 PASS / 23 FAIL (precision residuals + 000487 RR)
§4: 42 PASS / 12 FAIL
---
total: 151 PASS / 35 FAIL

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.
