Internal adversarial pass, not an independent review. Adds the cube-sum
(higher-order differential) command to bound the algebraic degree of the
applications: a low degree would admit a cheap polynomial batching of the 8
applications, so degree saturation at small d is the no-shortcut bound. Plan
section 8 records main's three-lane re-scope: this lane is the algebraic
structure of M_r.

Internal adversarial pass, not an independent review. The plan restates M_r
from the frozen crate and spec 1.8, ranks Q3/Q2/Q1/Q4, gives the method, the
planted known-fail shape and the box-hour estimate per step, and lists every
file opened. Records the byte-identity result: build/master differs from the
frozen commit in accept.rs, emit.rs, generator.rs, packcheck.rs and two test
files, but is byte-identical over memhard.rs, seed.rs, bind.rs, derive.rs and
the Cargo pin, which define M_r.
Harnesses: adv-mixer (new: diffusion margin for Q2, the fold probe for Q1,
with a planted-weak-day hook), f4-weakday (copied read-only from
build/attack-pass for the Q3 census), f8-uniform (copied from the regate
worktree).
