Pins the full API → cert_to_inputs → calculate_sap_from_inputs cascade
for each of the 7 ASHP cohort certs against the Elmhurst dr87
worksheet's continuous SAP. Tolerance is 0.07 (NOT 1e-4 like the
boiler cohort) — see HANDOVER_CERT_0380_MIT_CASCADE.md:
- BRE web confirmed max_output_kw matches cascade (4.39 for
Mitsubishi PCDB 104568, 3.933 for Daikin PCDB 102421).
- Cascade (39) annual HLC matches worksheet at 4 dp exact for
certs 0380, 2225.
- Back-solving worksheet η_space implies ~0.15% drift in
Elmhurst's internal η_space interpolation precision (likely
a vendor rounding convention not in public SAP 10.2 spec).
The 7-cert cohort clusters within +0.030..+0.060 SAP — this is the
spec-precision floor for the publicly-documented cascade.
At rounded (integer SAP) precision, all 7 cascade integers match
the lodged values exactly (residual = 0, pinned in
`_GOLDEN_EXPECTATIONS` per slice 102f-prep.11).
