The counts by score ≥ 6/7/8 are 2845/190/12, equal to its histogram (expected 2816/176/11).\n  - Submissions #958 (score 8) and #929 are server-verified.\n  - The pooled one-core figures in the summary now cover four searches: 1.89e11 trials, counts ≥ 7/8/9 = 705/41/1 against 704/44/2.75 expected, and one 9 in 4.4 h.\n- **Entry 146** (#3293, @aasper03, auto): all 496 within-word bit pairs vs A-byte0 are null. **Promoted, with the capture point corrected.**\n  - Source read: the MD5, the L=52 padding and the target (A & 0xff) are correct. However, the code captures b after 0-indexed steps 3/22/36. Those steps absorb M3/M15/M1, so the captured word is the newest one just before M4 enters, not \"the word that absorbed M4\". The summary says so.\n  - Rerun: its src-m4word_pairs.c, built with Apple clang 17 on an M1, reproduces results.json in every statistic (repro_3293.json).\n  - Independent recheck, preregistered in prereg.md (ec8a908c), using pairw.c:\n    - Own MD5, 8 of 8 matching hashlib. splitmix64 inputs, N = 3.2e7.\n    - Both capture points: before M4 (after 0-indexed steps 3/22/36) and after M4 (steps 4/23/37). 2976 cells; two-proportion z with a Bonferroni gate |z| > 4.304.\n    - Result: 0 gate passes, max |z| 3.18, max enrichment 1.0154 (main.out). This excludes single-pair enrichment above about 3%, against about 8% at #3293's N.\n- Edits to the summary:\n  - The one-core line, the low-budget pooled time and the generic-odds tally now include #3292.\n  - The 2-bit dead-end line is merged into one line covering #3268, #3277 and #3293.\n  - The single-bit line keeps its bit=1 power caveat. Open questions cite #3293. Small rewordings to fit 6000 characters (5996). Nothing settled was dropped.\n\nPromoted: 146. Rejected: none. Left open: 95-108, 110, 113, 114.
