User pivot at end of prior session: don't hand-build EpcPropertyData
fixtures — route Summary PDFs through `EpcPropertyDataMapper.from_
elmhurst_site_notes` so the pin grid exercises extractor + mapper +
calculator, and each new Elmhurst doc grows mapper coverage instead
of bespoke fixture code.
New fixture cert 000565 is a stress-test cert (5 building parts, age
mix A→J, conservatory with heaters, curtain wall, basement walls,
mixed party-wall constructions) that surfaces many uncommon cascade
paths absent from the cohort-2 + ASHP corpus.
Mapper coverage extended for 3 Elmhurst §11 glazing labels surfaced
on this cert (per RdSAP-Schema-21.0.1, `datatypes/epc/domain/
epc_codes.csv` glazed_type rows):
"Triple between 2002 and 2021": 9 (RdSAP-21 schema row 9 — triple
glazing, installed 2002-2022 in EAW; `_G_PERPENDICULAR_BY_
GLAZING_TYPE[9] = 0.68`, `_G_LIGHT_BY_GLAZING_CODE[9] = 0.70`)
"Single glazing": 1 (alias of bare "Single"; cascade
g_L = 0.90, g⊥ = 0.85 per SAP 10.2 Table 6b)
"Double glazing, known data": 3 (Elmhurst lodgement of RdSAP-21
schema row 7 "double, known data"; manufacturer U-value and
g-value lodged via WindowTransmissionDetails override the
cascade's defaults — grouped under code 3 with other unknown-
date DG variants for cascade-equivalence on g_L/g⊥)
Per [[feedback-e2e-validation-philosophy]] + [[feedback-zero-error-
strict]]: pin tolerances are abs=1e-4 against U985-0001-000565.pdf
Block 1 line refs (pinned: SAP int + SAP continuous + ECF + total
fuel cost + CO2 + space heating + main 1 fuel + secondary fuel +
hot water + lighting + pumps/fans).
Outcome: 1/11 pin green (`secondary_heating_fuel_kwh_per_yr = 0`);
10 pins are now named calculator-gap residuals to fix in subsequent
slices:
main_heating_fuel_kwh_per_yr +27,665.01 kWh/yr (heat-pump SAP code
224 + gas combi via WHC 914 "from second main"; cascade probably
runs ASHP for DHW instead of routing through gas combi)
hot_water_kwh_per_yr +164.88 kWh/yr (FGHRS / solar HW /
Table 3a no-keep-hot for the gas combi DHW path)
lighting_kwh_per_yr -236.19 kWh/yr (RdSAP §12-1 bulb-
count cascade; 27 total / 7 low-energy / 20 incandescent lodged)
pumps_fans_kwh_per_yr -122.52 kWh/yr (cascade defaults
to 130; expected 252.52 = MEV PCDF 500755 + flue + solar pump)
Cohort regression check: 472 pass + 10 expected 000565 failures.
Pyright net-zero (32 errors before, 32 after).
