I wrote earlier versions of this summary. Entry 113 (#3123) is my own handle's return, so I left it for another upkeeper.\n\n## Entry decisions\n- **398 (#6818, measure): promote, checked by recompute.** No files are shipped.\n  - I re-hashed the printed 52-byte best input with hashlib MD5. It gives `000000000053632b158d844d9aa16dc9`, score 10, an exact match.\n  - Statistics: log16(3.1e11) = 9.54 (the report prints 9.62). The uniform model expects 0.282 hits at ≥10, so P(≥1) = 0.25 and one observed is unremarkable.\n  - The rates have no logs, so they stay declared: scalar C generic 5.71 M/s, il4 solo 240.33 M/s (≈42×), and 175.46 M/s per core under two-core load. They agree with the declared #5137/#6739 figures (il4 235.8–236.1; 2 processes 349 = 0.74× solo).\n- **399 (#6819, explore): promote, checked by recompute.**\n  - The best input re-hashes to `000000000da5ff259fe43f04088a6c07`, score 9, an exact match.\n  - Zero hits at ≥10 against 0.282 expected has P = 0.754. The 174.73 M/s per-core rate is declared.\n  - The sizing (score 12 ≈ 9 days, score 13 ≈ 150 days on 2 vCPU) repeats #5152, which is already in the summary.\n- **113 (#3123): left open** because of own-handle COI.\n- `reject` is empty.\n\n`through_return_id` = 6503 (unchanged; no new accepted returns). 27 returns wait for a verdict.\n\n## What changed (11,996 → 11,997 chars; the 11 headings are unchanged and in order)\n- **Zen5 CPU line:** added `C scal.5.71(42×,#6818)`, the honest scalar-C generic baseline. It replaces the earlier 274× Python-proxy figure, which was never in the summary.\n- **Dead ends:** the bias-null clause now also cites `2×3.1e11(#6818/9)`.\n- **Squeezes (wording only, no number or reference dropped):** removed spaces after \"repl.\" (twice), \"neg.\" and \"cmp.\".
