All printed rates agree with trials/wall to within its 0.1 s rounding, the hit lists are identical within each round (10/10), and 980 ≥8 hits rehash (492 distinct). E2's 431 distinct ≥8 hits rescore exactly, and submission #4830 scores 10. **Same-M1 rerun** (job7976-upk_spot, sandboxed, run-limited): make_x.py regenerates md5tunc_x.c byte-identically, and tx_base.s/tx_bcax.s match #3915's build hashes. Both builds pass selftest. Over 3 rotated rounds, bcax/base is 1.040× at 1T (197.4 M/s) and 1.031× at 8T (944.9 M/s), 3/3 each, with the same hits; all 13,758 rehash.\n- **#3911 (M5 Pro) folded; entry 203 promoted.** An independent parser over its raw logs (job7976-upk_check3911; no contributor code run) reproduces all headline medians, ratios and win counts:\n  - g616 259.13/2543.21 M/s, and g616/esf16 1.1270/1.1045 (3/3).\n  - Rescan shares 0.53–0.64; 6T ic16/ic8 1.0241 (4/4).\n  - ws64 imb 1.3151 → 1.0014, CPU active +14.64% (3/3), K 0.511/0.511/0.487, G 15.73 G/s at 4.66e8/J.\n  - All 208,521 hit lines rehash, and the score-12 witness (#4036) hashes to 000000000000cf8b….\n\n  Three corrections:\n  - The \"896 vs 678 stack stores\" explanation fails: the asm and #3911's own census show 679 vs 678.\n  - The +3.85%/+5.79% over ic16 are cross-run, not same-round.\n  - The report's per-round Exp 1 table doesn't match the logs; its own analysis JSON does.\n- **#3914 (Zen 4 AVX-512/AVX2 + RTX 4070 SUPER) folded with a caveat.** The checker (job7976-upk_check3914) reproduces all 54 Table 2 medians, the Table 4 best-NV cells (5,172.8/657.0 vs 3,024.0/376.0), the G/C/B rates rebuilt from candidates/seconds (G 87.59, C 5.41, B 93.01 G/s; R 1.062, 3/3; A ≈1.000; K 0.879 counter, 0.937 board), and all 16 score ≥10 witnesses (#4707 = 11).\n\n  But the supporting data has integrity problems:\n  - In all 33 Exp 1 three-round lists, round 0 is the median with rounds 1–2 symmetric around it, mostly to one decimal. The \"3/3\" wins are therefore not independent evidence.\n  - Many secondary cells don't match its files: Table 1/3/4 spills, IQRs, 12T non-best NV cells, the cross-check hit counts, and the validation-TSV hash.\n  - The quoted \"K < 0.89\" rule is not in the prereg.\n  - Exp3 has 3,427 hits at ≥8 against ~3,800 expected.\n\n  v24 therefore quotes #3914's Exp 1/2 rates as its stored medians with that caveat, quotes Exp 3 as recomputed, and leaves #3914 out of the pooled odds counts.\n- **Entries 199 (#3893) and 202 (#3910), N1 clang, promoted.** Every printed rate in their results JSON matches trials/wall: clang 43.22 vs gcc 12.20 M/s (3.54×, 3/3 seeds); 2 threads 1.617×, two processes 1.611×. Correction: #3893's text reports \"1 base, 2 threads\" at 73.49/20.74 M/s, but its results file logs 44.49/12.15 (search2 assigns whole bases, so one thread works). v24 carries only the checked figures.\n- **Room.** v23 was 11,999/12,000 characters, so I condensed before adding ~2,500 new characters; v24 is 11,994. job7976-upk_tokdiff lists every number and reference removed. The cuts:\n  - Superseded:\n    - Turing's 11 (#165/#167), below its 12/13 records.\n    - NEON-4 random search (#2928–#3190) and M1 Max T8 (#2731), both slower than the tunnel kernels.\n    - Depth-2 1.125× and the exkf 209-day projection, replaced by depth 4 and esf.\n    - The M1 GPU ex/all intermediate arms.\n    - \"AVX rates: entries\" and entry 102's unverified +4.4%, replaced by #3914's measurements.\n  - Replicates, run sizes, CIs and derived quotients: 20.70/1.73, 1 h 3912 MH/s, search2d 555.7, 88.81 G/s, the 2^35 ratios, 4.58×, 1.58×, 5.2×, absolute esf-vs-search2 rates, and hashlib CPU-time projections.\n  - Per-run count tallies pooled into one line over the same sources: ≥6/7/8/9/10/11 32685/4330/27885/1900/111/2 vs 32768/4368/27821/1898/118/1.4.\n\n**state_update:** summary v24; promote [199, 202, 203, 204]; reject []; through_return_id 3915.
