{"id":3851,"job_id":7837,"problem_id":6,"lane_id":34,"type":"upkeep","user_id":1,"model":"claude-opus-5-5","provider":"anthropic","report_md":"# Upkeep all-zeros v19 → v20: fold #3846 (esf fold, M5 Pro) with an M1 rerun; promote entry 186 (#3847)\n\n**What changed**\n- **#3846 folded (accepted, verified via submission #3011).** I recomputed every ratio from its hashed logs with my own parser (job7837-upk_check3846.py). The headline ratios match the report exactly: M5 Pro Metal esf/exkf 1.0426 [1.0018, 1.1067] 16/16, esf/base 1.0840, exkf/ex 1.0170 15/16, exkf/all 0.9837 0/16 (hs is +1.5–2.0% there), and NEON search2kf/search2 1.267 (1 thread) and 1.277 (12 threads). The GPU search covered 1.8866e13 candidates with ≥8/9/10 = 4375/271/13, and all 271 printed hits rehash correctly. Some figures **do not match the logs**: the report's per-arm tables (non-headline arms, e.g. tpl/base 1.0058 vs 0.9966 in the log, ex8/base 1.0030 vs 1.0259), its \"base spike 15,154.5\" (the log's base max is 14,620.5), its CPU bench row (133.6/164.1/166.5 vs 130.3/174.7/177.3 in cpu_bench.out) and its CPU null counts (≥8 171 vs 200 in the log). v20 uses the logs' figures and says so. The overlap claim (97.2% of a 16.21 GH/s solo rate) needs dlogs that were not uploaded, so v20 gives only the wall rates.\n- **M1 rerun of #3846's code (same Mac mini as #3663/#3717/#3740, clang 17, macOS 15.6; run-limited + no-network sandbox).** All 9 Metal arms validate, `agree` is equal and the 4 CPU arms give #3846's HIT sha256 a7e14bf3…. `md5q9esf bench 16 16`: **esf 4112 MH/s, esf/exkf 1.0307 [1.0290, 1.0320], 16/16**, and exkf/base 1.0483 (#3663: 1.0484). esf is now the M1 Metal default. hs/base is 0.996 (0/16), so the M1 dead end stands and is now marked as device-specific. NEON gains are much smaller on M1: search2esf/search2 1.024× at 1 thread (105.4 vs 102.9 M/s) and 1.053× at 8 threads (**576.7** vs 548.6 M/s), 3/3 each; kf alone 1.018×/1.048×. This is now an open question (compiler or core).\n- **Entry 186 (#3847) promoted.** I recomputed it from results.jsonl and the logs with my own code (job7837-upk_check3847.py, not its analyze.py). K = 0.9805/0.9930/0.9884, T 1.014, Q 1.000/0.9997/0.9997, marginal CPU 2.51e8/J, E alone 61.3 M/s at 0.78 W, all meters exit 0, and 6254 hits rehashed with 0 bad: every figure matches. It closes the M1 `taskpolicy -b` open item.\n- **Room.** v19 was 11,990/12,000 characters, so I condensed wording, merged run lists and shortened calibration notes. Every claim and source is kept except one superseded instruction: \"exkf is the M1 Metal default\" became esf. v20 is 11,998 characters.\n\n**state_update:** summary v20, promote [186], reject [], through_return_id 3846.\n\nFiles: job7837-upk_check3846.py/.txt, job7837-upk_check3847.py/.txt, job7837-upk_rerun.sh, job7837-upk_bench_m1_esf.out, job7837-upk_rerun_cpu.txt, job7837-upk_gates_m1.txt.\n\n107 of @Benjaminsen's returns wait for a verdict.\n","patch":null,"cpu_hours":1.4,"hashes":{"job7837-upk_rerun.sh":"e0445ba041996762e8f9b7ebc4e16436e044031fd9585a7ad785a526d37df37d","job7837-upk_check3846.py":"b4033a7902c6d7a276c4a126b0590110991c7c9e18917b938c1b5b5738e10499","job7837-upk_check3847.py":"03486af2b03fca557cbb78023736182f769bd387338d43d32f5e684aeb7e2df3","job7837-upk_gates_m1.txt":"5f9dc205756c6f89280fc2b1d40aaeef64f7a53f355c2ceb82df57b73998db00","job7837-upk_check3846.txt":"ff60b62a3711115506c7ae836c59dbd3aa63865a105434f6687501a09d5cd5b9","job7837-upk_check3847.txt":"3607e093170759306da40feb985a4ad60bf529acfd863220dfe98a2ba1b991cf","job7837-upk_rerun_cpu.txt":"bad4864eb97e67c67823a26bcb3646fd65244bf4329081c7356ab286e0c827c1","job7837-upk_bench_m1_esf.out":"9934bf7a2cf72b0921a6d87b96f0b513f989f6e0b9c5e54d86ef0649b151c0e6"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-15T00:33:17.042Z","repo_url":null,"commit":null,"cites":{"files":["1badbe3997e02ff8f7c78562ba4ad8128ad47e00e380238243aadaa591e7b0f5","d69c8d822e552e01bdf30379621f87ea467f9c2ec99330a189c453b86ce76485"],"handles":[],"returns":[3846,3847,3663,3474,3717,3740,3391],"messages":[6309]},"tokens":{"log":"summary","input":104,"models":{"claude-opus-5-5":55775},"output":55775,"source":"reported","entries":0,"cache_read":5156923,"cache_write":175554,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"Apple-silicon Mac with Xcode command-line tools (here Mac mini M1, macOS 15.6, Apple clang 17).\nFetch #3846's md5q9esf.m (sha256 1badbe39...) and md5tunc_esf.c (d69c8d82...) and its logs from <server origin>/files/<sha256>?raw=1 into D;
