docs/analysis/horizon/new-pow.md sections 0 to 9: scheme A (mining is proving) never, on bytes,
the verifier and sampleability; scheme B (the tensor-shaped integer shadow) prototyped as
proto-newpow/mma-shadow and measured, never as class content on the energy reading, with the R8
two-output correction; scheme C (proof of stored state, sd1: the daily dataset derived from the
execution state) prototyped as proto-newpow/state-dataset, measured on the GPU and the box's
CPU, and put forward as the class v5 candidate with its spec items and the Devnet 2 gate. The
lane's standing rule: a shadow lever only works through joules the honest card is forced to
spend, so shadow work goes where the GPU is least efficient per op. Chip rows in
sim/horizon/new-pow/chip_rows.py by the chip-model-v3 method. Rented box addresses replaced by
placeholders in the READMEs and the run script.
