Captures the 4-slice arc this session — Table 32 default prices (sap_score
28 → 29 EXACT), Table 12a Grid 2 dual-rate CO2 (CO2 65% closed), extractor
gable_type recognition + mapper preservation of cert 9501, and the full
RR mapper + cascade fix per RdSAP 10 §3.9.2 + §3.10 + Table 4 (11
per-BP RR surface areas EXACT vs worksheet PDF).
Documents the BP main-wall residual −161 W/K diagnostic localising the
next slice block to two spec-cited cascade gaps: Curtain Wall (−112
W/K, no _ENG_WALL entry for WALL_CURTAIN=9) + thin-wall stone granite
alt (−47 W/K, _insulation_bucket short-circuit + thin-wall §6.6/§6.7
formula). Each spans extractor → datatype → mapper → cascade and is a
single coherent slice when the spec lookup is tractable.
NEXT_AGENT_PROMPT_POST_S0380_84.md prescribes S0380.85 (Curtain Wall)
as the highest-leverage next slice with audit + implementation +
expected-outcome details.
