Khalim Conn-Kowlessar 6e6bba7e67 Slice 26c: §7 mean internal temperature cascade pin (44/60 PASS) ... Added `mean_internal_temperature_section_from_cert` composing §1 (dim) + §2 (effective_monthly_ach) + §3 (total HLC) + §5 (internal gains) + §6 (solar gains) + climate (external temp) and threading them through the §7 orchestrator — exact mirror of the cert_to_inputs internal cascade. Added 60 strict pin cases for §7 worksheet lines (85)..(94): T_h1 scalar, living_area_fraction scalar, η_living + T_living + T_h2 + η_elsewhere + T_elsewhere + T_92 + T_93 + η_whole monthly tuples. §7 per-fixture monthly pin status: fixture | passing 000474 | 6 of 8 (LINE_92/93 ~0.0001 K residual) 000477 | 6 of 8 (LINE_92/93 ~0.0002 K residual) 000480 | 6 of 8 (LINE_92/93 ~0.0001 K residual) 000487 | 0 of 8 (cascade from §3 RR + §4 HW defects) 000490 | 6 of 8 (LINE_92/93 ~0.0001 K residual) 000516 | 8 of 8 ✓ LINE_92/93 marginal fails on 4 fixtures: weighted-sum of T_living + T_elsewhere drifts by ~1e-4 K from PDF despite the per-zone temps matching at 1e-4 individually. Likely a PDF intermediate-precision artefact (analogous to U_eff at 5 dp in §3 windows); investigation deferred — no widening per project policy. Scoreboard: section_cascade_pins: 230 → 274 PASS (+44; 60 new tests, 16 fail) e2e SapResult: 32 → 32 PASS (unchanged — §7 cascade was already running internally, pin tests just surface the line refs) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-23 21:50:12 +00:00
