Update NEXT_AGENT_PROMPT.md for the TDD session that landed 3 more
slices on top of Session 1's fabric work:
58: secondary fuel cost routes through lodged secondary_fuel_type
(closes the biggest single gap on cert 001479 — 9 SAP)
59: heat_transmission apportions windows per bp via window_location
60: thermal bridging y uses primary bp's age (dwelling-wide)
Chain pin `test_summary_001479_full_chain_sap_matches_worksheet_pdf_
exactly` is committed RED as the load-bearing TDD forcing function:
Pre-workstream: delta +5.84 SAP (cascade 63.17 vs target 69.0094)
Post-Slice 60: delta −1.19 SAP (cascade 70.20 vs target 69.0094)
Per-bp fabric U-values all match the worksheet exactly. Remaining
1.19 SAP overshoot maps to ~3 W/K of HLC undercount in roof + floor:
- Ext2 PS sloping-ceiling roof area uses floor projection (1.92 m²)
instead of slant area (2.22 m²). −0.81 W/K.
- Main ground-floor U: `u_floor` Table 19 returns 0.60 for age C;
worksheet expects 0.65 (same as age B). −1.52 W/K.
- (31) external area under-count drives bridging gap. −2.08 W/K.
Slice 61 (SapFloorDimension.floor_lodged_u_value override using
Summary §9 "Default U-value") was attempted and reverted: closed
001479 floor gap exactly but broke 000474 cohort's 1e-4 pin (its
cascade calibration uses u_floor age-B 0.77 vs Summary's lodged
0.75). Next session needs a different fix — Table 19 audit for
age C, or selective override.
