Updates the PV β-split handover doc after the three new slices land:
- S0380.47 cost cascade wiring (zero cohort impact via Table 32 collapse)
- S0380.48 real-API battery_capacity schema gap (cohort PE +2.7..+8.1
→ -3.5..-4.5)
- Restates the open slice (S0380.49) as wiring effective-monthly
Table 12e PE factor into the PV cascade — the remaining ~4 kWh/m²
PE delta is structural (currently uses annual factors instead of
monthly-weighted).
Key narrative correction: the prior handover's "E_PV magnitude bug"
hypothesis ("cascade thinks 2570 kWh/yr vs worksheet 831") was wrong.
Reading the cert 0380 worksheet PDF directly (dr87-0001-000899.pdf
page 3 line 233) shows -2563.3692 kWh/yr — matching our cascade
exactly. The real bug was the schema dropping flat-shape
battery_capacity, fixed in S0380.48. Lesson captured in the doc:
verify handover-cited numerics against the source PDF before
implementing the prescribed fix (same discipline as spec-floor
skepticism applied to handover claims).
Includes the full PE residual cohort table across all three milestones
(pre-44 / post-45 / post-48) and the Slice 6 implementation outline.
