test(corpus): ratchet SAP floor 0.65->0.67, ceiling 1.08->1.00

Browse source 
Lock in the detailed-RR slope + stud-wall gain (corpus within-0.5
67.3% -> 67.5%, MAE 1.020 -> 0.987). The corpus is a fixed 1000-cert
deterministic gauge, so the thresholds track measured HEAD with a small
margin per the ratchet convention.

# DETAILED RR SLOPE + STUD WALL (RdSAP 10 §3.9 Figure 4 + §5.11.3 Table 17 cols

# Those fields were UNDECLARED on the schema, so `from_dict` dropped them and the
# mapper built only gable + flat-ceiling — the (large) sloping roof and knee
# walls contributed ZERO heat loss -> undercounted RR fabric -> over-rate.
