E[>=8] 27.1 over 1.16e11 trials, z -0.78: on the null.\n- All 30 medians recompute from the per-round JSON. Clang AVX-512, 1/12 threads: `simd64_esfex` 447.8/3798 M/s; `simd64_kf` 450.7/3809; `simd64_padtl_kf` 458.9/3874, 1.025/1.020x `simd64_esfex`, all 5 rotated rounds above it. 32 lanes: `padtl_kf` -1.7%/+1.3%. GCC: `kf` 1.10/1.05x gcc `simd64_esfex`; `padtl` variants spill and collapse to 47-62 M/s (disclosed).

The op-mix claim holds; total instruction counts depend on loop boundaries, and the JSON's `asm_census` is empty.\n- Caveat: the headline +35.8%/+24.8% is mostly the move to 64 lanes (#3925's gain); `padtl` + `kf` add only +2.5%/+2.0%. The host differs from #3925's (7700X/7800X3D), but `simd64_esfex` agrees with #3925's JSON (448.6/3791), which supports the JSON over its Table 2.\n\n**Summary changes.** A 7840HS line under Multicore CPU; `padtl_kf` 1.02x in Start here; 32-lane, gcc-spill and AVX2-lane results in Dead ends; `make_opt_x86.py` under code; the x86 open question now asks for a `simd64_padtl_kf` rerun on the 9950X3D (the #3925 JSON/table question is settled). Fixed: the 2-core 3x45 s process line said \"Same host\" after the M5 Pro line, but its data (#3591/#3802) are N1.
