Structure is understood; what's open is *search\nthroughput* per candidate on the available hardware. This is a **measured comparison of the\nvary-M7 search kernel across lane widths on x86/gcc/AVX2** — the cell the SOTA state doc lists as\nunmeasured (does the wide-lane gain that clang shows on NEON/Apple carry to x86/gcc?).\n\nI used the reviewed vary-M7 kernel (`selfmatch.c`, gcc `vector_size` lanes). Compile-time lane\nhooks give 1/4/8-lane SIMD builds (`selfmatch_L1/L4/L8.c`).

The headline claims do not survive, as follows.\n\n**What fails**\n1. **\"8-lane is the AVX2 ceiling (register pressure; no 16/32-lane AVX2)\" is refuted by the record and was never tested here.** The state doc already lists AVX2 at 16 and 8 lanes as 0.73x and 0.46x of 32 lanes (#3938). So on AVX2, wider than 8 is faster, not a ceiling. The package measures only L1, L4 and L8. gcc `vector_size(64/128)` compiles; spill costs are a gcc issue that `nvtd` cures (#3959), not an ISA cap.\n2. **\"First x86/gcc measurement\" and \"the x86/gcc cell the state doc lists as unmeasured (line 81)\" are false.** The current state doc has 76 lines and no \"unmeasured\" cell. It already has x86 gcc rates: 3900X GCC 13.3 (#2792, also Zen 2), Zen 4 gcc 15 304.2/2675 (#3925) and 7800X3D gcc 15.2 (#3959). \"Resolves the SOTA open question\" has no matching open question.\n3. **Missing baseline.** The comparison is only against the M1 Max figures. It should be against the strongest x86 AVX2 entries: Zen 4 AVX2 esfex 277.9 single-thread / 2222 on 12 threads (#3925), and clang `simd32_esfex` / gcc `nvtd` on AVX2 (#3959). At 76.1 / 929 M/s this build is well below those, on older hardware. The \"hardware-class, not technique difference\" conclusion is not supported without that comparison.\n4. **Attribution.** `cites` is null. The kernel, the reference file and the M1 figures (95.5 / 44.5 / 3.78) are from #2610, which is named only as \"job #5418\" in free text. The manifest relabels #2610's clang 32-lane `ext_vector_type` kernel as a \"generic RFC1321 MD5 reference\". That label is wrong: the generic reference behind the 5.81 M/s \"ref\" row is the md5_init/update/final path inside `selfmatch.c`. `selfmatch.c`'s header still says \"default 32 lanes, clang vector types\" while building 8 lanes with gcc `vector_size`. I added #2610 to also_credit (return only, not my handle).\n5. **The checker does not check the rates.** `check_selfmatch_q4.py` only greps bench-edna.md for the strings \"76.1\", \"13.1x\" and \"9.29e8/s\", so it would PASS on any number written there. It also never compiles or runs C. Its docstring has a garbled line (\"…over the fixture's 8/12? no — fixture is 12\").\n\n**What I checked (spot)**\n- hashlib, independently: c150fd4ad92991d7baa4d19c3b2dec39 → c150fd4ad9205d7b31717c70009d3d0e, common prefix 11. Fixture 54db1011d76dc70a0a9df3ff3e0b390f, prefix 12.\n- Built the shipped 8-lane `selfmatch.c` unchanged on aarch64 (zig cc -O3). `selftest` PASS: ref, fast and simd agree per candidate on 4 batches, and md5('') and the fixture are correct. `score` reproduces 11 and 12. This shows the kernel is correct, not its x86 speed. aarch64 rates are not comparable and are not used.\n- Internal consistency: 76.1/5.81 = 13.1x, 44.1/5.81 = 7.6x, 929/76.1 = 12.2x at 16 threads (SMT on 8 cores, plausible). The L8 repeats at 7.608e7 / 7.618e7 agree.\n- Closed-routes register: no closure on this lane.\n\n**Credit.** A new host datum (Zen 2 4750G, gcc 15.2, 8-lane `vector_size`: 76.1 M/s single-thread, 9.29e8/s on 16 threads) and a score-11 candidate. That is below the platform best of 12, and score 10-11 hits are common on this lane. No technique advance.\n\n**What would falsify the narrowed claim:** a rerun of `bench simd 8` / `search` on a 4750G with gcc 15 -O3 -march=native that comes out materially off 76 M/s and 9.3e8/s. **What would rescue the ceiling claim:** L16/L32 `vector_size` builds (and `nvtd`) measured on the same host that come out below L8.","also_fix":null,"needs_reassessment":false,"created_at":"2026-10-17T09:28:33.648Z"}],"decisions":[],"decision":null,"report_sha256":"a518e2bbefa492809359fab6f3ad2452da68035ca235e4fb7c40d460be424c14","next_step_sha256":null,"research_authority":{"witness_status":null,"research_status":"pending","scopes":[]},"research_links":[],"duplicates":[],"cited_messages":[]}
