Internal adversarial pass, not an independent review. Q1 (this lane, the
algebraic structure of M_r): the fold probe and the integral cube-sum degree
test on the frozen-identical binary show no composition cheaper than 8x. No
affine fold, no word separability, no key-order commutation; algebraic degree
>= 16 after one application and saturated after two. The 9,360 ops per item
stand. Q2 margin (full diffusion at 2 applications) and Q3 census (best day a
1.17x FPGA multiply datapath, 1 in 2^24, zero wall-time gain, ROT-all-equal
never seen) kept as courtesy runs attributed to adv-mixer-3 and adv-mixer-2.
igneum-pow merged to build/master and re-proven byte-identical to c3d32437;
pre-merge runs re-run on the merged tree and matched. Logs copied into the
branch so the report paths survive; run-box.sh writes outside the mirror.
