Khalim Conn-Kowlessar 2f3b1dbd3f test(modelling): Solar PV Elmhurst cascade pins + battery tripwire
Slice 9 of the Solar PV Recommendation Generator (ADR-0026). Pins the
overlay→calculator PV cascade against Elmhurst's before/after re-lodgements of
cert 001431, across the orientation/pitch/overshading config space (the certs
lodge synthetic 1.00 kWp test vectors):
 - SE/SW, shaded (overshading 3/2), pitch 30°/45°
 - E/W, unshaded, pitch 60°/45°
 - NW/N, unshaded, pitch 60°/45° (the low-yield orientations)
Each hand-built SolarOverlay reproduces the relodged after at abs ≤ 1e-4 on
SAP / CO2 / primary energy.

Battery tripwire (per user): the "with battery" cert lodges a §19 5 kWh battery
the current extractor does NOT parse, so it scores identically to its
no-battery twin — the no-battery overlay reproduces it today, and the pin will
fail (alerting us to switch to the with-battery overlay) once the extractor
parses the battery. A companion test pins that the calculator already models
the 5 kWh battery (it raises SAP), so the fix target is established.

All five certs share an EES 'WGK' / SAP-code-502 main-heating lodgement the
mapper doesn't yet derive a fuel for; the pins patch the shared fuel (mains gas
26) identically on before+after to isolate the PV delta (the solar overlay
never touches heating), and `test_solar_before_baselines` xfails as the
forcing-function tripwire for that separate mapper-front gap.
