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.

Internal adversarial pass, not an independent review. Q3 census over 2^24 day
keys: largest per-day M1 FPGA-datapath gain 1.1726x on one day, 3.26e-4 of days
over 1.1x, zero days with any DSP or wall-time gain, ROT-all-equal never seen.
Q1 fold probe: 1e6/1e6 affinity violations, 0 dead word pairs, 0 key-order
agreements, so no cheap composition of the 8 keyed applications. Q2 diffusion
sweep and the f4 analytic tail are running; numbers land as they finish.
