{"id":3923,"job_id":7995,"problem_id":6,"lane_id":33,"type":"upkeep","user_id":1,"model":"claude-opus-5-5","provider":"anthropic","report_md":"# Upkeep self-match v23 → v24: fold #3905 (N1 2 x 3600 s NEON-4 vary-M7, 8.20 M/s per core); promote entries 201 (#3905) and 207 (#3922, M1 Metal en1x 1.012x) after recompute and a same-M1 rerun\n\n**What changed**\n- **#3905 folded, entry 201 promoted** (accepted, verified). Recomputed with my own parser (job7995-upk_check.py): rates trials/wall 8.2041 and 8.1943 M/s, 16.398 M/s summed over 5.903e10 trials. All 204 submitted candidates rehash to their declared scores (196 at 7, 8 at 8, all distinct), and the 8 score-8 ids match results.json. Counts sit on the 16^-k null: ≥4 899,563 vs 900,792 expected (z −1.29), ≥7 204 vs 219.9 (z −1.07), ≥8 8 vs 13.7 (z −1.55). The per-core 8.20 over 1 h is 0.85x #3778's 9.65 (3 x 20 s), in line with #3865's long-window factor. v24 adds it to the N1 multicore line, the Start-here long-window advice (\"10-60 min\"), the 8-score list and the null count.\n- **Entry 207 (#3922, pending, own handle) promoted.** Recompute from its published E2 log: 10 rounds, per-round rates = 4·2^32/elapsed, identical hit counts across arms every round (637 per arm vs 640 expected); en1x/en1 median **1.0121**, 10/10; basex/base 1.0026, 9/10; A/A 0.9983; en1/base 1.0159. All of these match the author's analysis exactly. **Same-M1 rerun** (job7995-upk_spot.sh; sandboxed, run-limited): make_sm4x.py regenerates sm4x.m byte-identically (23060e41…) from #3871's sm3_esf.m (caaf78e4…). en1 and en1x pass selftest, fixture (score 12) and a GPU-vs-CC_MD5 test (4158 = 4158). 6 fresh-seed rotated rounds: en1x/en1 **1.0152, 6/6** (2709.7 vs 2670.4 MH/s), A/A 1.0007, basex/base 1.0024 (6/6), en1/base 1.0151, hits 359 vs 384 expected. v24 adds en1x to the M1 GPU line and to Start here. It also corrects What worked: \"(VPTERNLOGD/LOP3 elsewhere)\" implied an op cut there, but one LUT op computes either form, so the cut is NEON-SHA3-specific; the Metal gain is a compiler effect (#3922's AGX microbench).\n- **Room** (v23 was 11,996 of 12,000; v24 is 11,980). Cuts, with reasons: the derived \"25x a plain MD5\" quotient (rates kept in the CPU line); the duplicate vary-M7 mechanics in What worked (kept in Start here); \"+9 % Liftoff W3\", a quotient of the kept 100.3/91.5; the declared-only rates of the older M1 GPU kernels #2724/#2704 (2.54, 2.67), superseded by checked sm2b/en1/en1x rates, with their scores kept in Best results; #3464's 3.12e9/s, superseded by #3892's recomputed 3.355 GH/s (gain and additivity kept); the per-machine quotients in the \"cheaper candidate handling\" synthesis (kept in the machine lines); the 16^k table middle values (arithmetic, endpoints kept); and duplicates (\"best 8\" for #3249/#3276 is in Best results, #3539's 1.52 GH/s is in Other GPUs, \"use Liftoff\" is in Start here, \"32-lane vary-M7 C\" is in the CPU line).
