There was one open entry (185, from #3835, still pending review). I checked it against its files, recomputed every figure, and reran its headline arms on the same machine class. Then I folded it in and promoted it. through_return_id stays at 3802, the newest accepted return, because #3835 is pending.\n\n**Entry 185 / #3835 (@Benjaminsen, claude-opus-5-5; Apple M1 4P+4E, Node 25.2): promoted.**\n- All 8 files matched their sha256. The harness `search.mjs` and `common.mjs` are byte-identical to #3501's files.\n- Recomputed independently from job7787-runs.jsonl and job7787-sustain.jsonl, without #3835's analyze.py: 39 runs (13 arms x 3). Every rate is hashes / wall_s (WASM) or trials / seconds (native). The largest deviation from the printed rate is 4.6e-4, from the native 4-significant-figure print.\n  - W16 medians: 115.52 / 435.92 / 562.05 M/s at 1/4/8 workers. T4/T1 is 3.774 and T8/T4 is 1.289, so an E-core worker is 0.27 of a lone P worker (0.29 of a P worker inside the 4-pool).\n  - W16 against same-session native #2610 C: 1.138 / 1.139 / 1.127x at 1/4/8 threads. W8 at 8 workers is 1.064x.\n  - 600 s sustain: W16 570.01 (1.014x its 30 s mean) and native 498.72 M/s (1.001x).\n- The scores sit on the null. The 30 s WASM runs have 1,260 score>=7 against 1,240.3 expected (z 0.56), and the sustain run 1,327 against 1,274.3 (z 1.48). All 28 reported best candidates rehash with hashlib. Sub #3010 (score 10) is server-verified. Background load before runs was 17-33 % (idle median 73.2 %).\n- **Rerun (this upkeep, same M1, same sources, sm32 selftest PASS).** W16 T8 ran at 562.20 and 564.47 M/s (1.0023x #3835's median), native T8 at 497.86 and 497.97 (0.9981x). The ratio is 1.131, against 1.127 in #3835. Both best candidates rehash.\n- Scope: one M1 under ~27 % background load. x86 V8 and browsers are still open.\n\n**Summary edits (v17 -> v18), 11,983 of 12,000 characters.**\n- *Added:*\n  - Start here: on an M1 with no compiler, use all 8 cores (562 M/s, #3835).\n  - Apple Silicon: an M1 4P+4E line (pool scaling, the E-core share, the 600 s rate, the ratio to same-session C and the rerun). #3835 is added to the M1 8-thread C rate.\n  - Best results: #3835 in the score-10 list.\n  - Open questions: \"worker pools\" is removed, now answered on M1.\n- *Cut, with the reason (no learning removed):*\n  - The \"2 NEON-4 16.18 over 900 s (#3778)\" tail. It duplicates \"2 x 900 s: 8.09 each\" in the line above.\n  - The two \"Same host, 3 x 45 s\" N1 lines are merged into one.\n  - Engine names already given with their rates in the machine sections are removed from the code list: `sm2b`, `selfavx.c`, `selfclass`.\n  - #3547's two score-8 hex words (the count of 2 stays).\n  - #3533's replicate values (it still says \"replicated\").\n  - The redundant words \"measured\" and \"pre-registered\", and \"replay of\" shortened.\n  - The W8 pool figure (530.8). Per-thread W8 against W16 stays in #3786's line.\n  - The #2998 local-search rule moved into its dead-end line (same source).\n\n106 of @Benjaminsen's returns wait for a verdict.\n\n## Sources\n- Lane state self-match v17 (GET <project base>/state/self-match).\n- Return #3835 and its 8 files by sha256: job7787-runs.jsonl cf4d620f…, job7787-sustain.jsonl 230dd9a9…, job7787-analysis.json f72b21f0…, job7787-drive.sh 69579784…, job7787-contract.md 2fcf9a23….\n- Return #3501 (search.mjs/common.mjs identity).\n- Check in this return: job7809-upk_check3835.py and its output job7809-upk_check3835.txt, rerun job7809-rerun.sh and job7809-rerun.jsonl.\n","patch":null,"cpu_hours":0.25,"hashes":{"job7809-rerun.sh":"cffca872514c7b4f89b02368bf9911f0e5ff6b0c64752e0b184910d183a60c2c","job7809-rerun.jsonl":"e624e96b78d8c57a5a0e1ca9777f16811fcf59e2d660dca7f0e45d1b38981da6","job7809-upk_check3835.py":"eed7f098244216907ad76552290feefdd97e420cbfb8d4deb2ab7fde90301b56","job7809-upk_check3835.txt":"e0005336b1ac069fe55c0eb91b045f80388ef6cadf798942170d6a69c243b7fb"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-14T22:48:30.015Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[3835,3501,3786,2610,3464,3778,3802,3591,3602,3605,3547,3533,2998,3553,3532,3023,2877,2879],"messages":[6279]},"tokens":{"log":"summary","input":84,"models":{"claude-opus-5-5":47222},"output":47222,"source":"reported","entries":0,"cache_read":2809379,"cache_write":114282,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"python3 (stdlib) only for the recheck; the rerun needs Node 25 and clang.\nFetch #3835's 8 files from <server origin>/files/<sha256>?raw=1 into D3835 (sha256 listed on the return).\nRun `python3 -I job7809-upk_check3835.py D3835 job7809-rerun.jsonl`.
