Counter ASIC 3.0 gates (hash): ledger AP-F8-1, the suite (103 of 103), CI and census lines at a5d735b2; the census draws in parallel

Suite at a5d735b2 on box 2: 103 passed, 0 failed (lib 140.8 s: every class v4 draw in the tests pays the 2^20 ratio pass). CI 37639406567 success. Census: 4,099 programs, 0 lossy sites of 65,584, 0 exhaustions, mean attempt 2.086 (a3859c1f 1.998), max 17; the ratio refuses about 4 percent of candidates that pass every other test. tools/ca3-v4-uniform draws the seeds across the available cores (the serial run became a four-hour job under the ratio pass); the analysis and the row order are unchanged.

 Sub-version 3, second commit (7 October 2026, 14:44 UTC, the hash lane; the sub-version number stays 3 and the stream is unchanged: re-export diff 0 on the eight packs, the id a785001687d8688a, the seven fingerprints and the zip sha256 stand), two rules. The shared-operand rule, in the draw's source rule and in the acceptance's (a') pass: or-then-xor or or-then-sub on one operand is `d & ~s`, xor-then-or is `d | s`, so the second write leaves the register lossy although either op alone injects; any write to either register clears the relation. On p23 the chain's attempt 1 (id d65122675f16a1c7) now draws site 7 (instruction 38) from r5 and passes; the devnet epoch-0 seed still draws attempt 1, the same program. Rule (c''), the distinct-index ratio: over 4,096 units (2^20 evaluations per site, the closed-form words, the shadow executed) every load site's count of distinct word indices against the uniform expectation on its window (N - N^2 / 2W, the window 2^28 >> min(win, 2)) must reach 0.98 (`MIN_DISTINCT_RATIO_V4`), the last test of the chosen candidate; a candidate under it is rejected and the next attempt drawn under the 256 cap and the last resort. The floor from the 64-seed run at 2^20 (box 2): the 55 clean seeds' minimum over their site rows 0.9960 (p1 0.9990, median 1.0000); the strong five p23 0.8361, p18 0.9274, p19 0.9335, p15 0.9432, p56 0.9654; 0.98 sits 0.015 from each side. The chain's own candidates it refuses (the test `class_v4_distinct_ratio_rejects_the_low_entropy_band`, box 2, 2.1 to 2.2 s each): p15 attempt 3 id 52638ea2e8b0fd68 site 2 at 0.943, p18 attempt 2 id 9a37e9489d8ba698 site 6 at 0.927, p19 attempt 0 id 79d7441de0689223 site 15 at 0.933, p56 attempt 2 id 486a8ad2701ec3b5 site 2 at 0.965; p23's attempt 1 with site 7 put back to r6 is refused by (a') (`UnfreshLoadSource`) and, run anyway, by the ratio at 0.836 (874,928 distinct of 1,048,576). Main's rule for a staged 2^24 pass (taken only if 2^24 separates the weak four from the clean seeds by at least the 2^20 gap) was decided by the 2^24 lines (box 2, 35 s per seed on one core): the weak four p34 0.9181, p4 0.9614, p8 0.9630, p10 0.9612; the clean seeds p44 0.9612, p52 0.9613, p3 0.9971, p2 and p5 1.0004; p23's attempt 1 1.0004. Two clean seeds sit on the weak four's value, so a 2^24 floor that reaches the weak four rejects clean seeds, and the 0.961 that recurs on both sides is a band the ratio reads at 2^24 that F8's hot-set gate did not flag on p44 or p52. Committed: the ratio at 0.98 over 2^20 alone (`ACCEPT_UNITS_DISTINCT_V4` = 4096), no 2^24 stage. Open tail: p4, p8, p10 and p34 (1.22x to 1.50x on F8's gate) read 0.9927 to 0.9963 at 2^20, inside the clean spread; unattributed and chased. The (B) most-repeated-value bound stays in the file unwired (`MAX_SOURCE_REPEAT_V4`, `most_repeated`). Cost: the chosen candidate's acceptance gains one 2^20 pass, 2.1 to 2.2 s on one box-2 core, once per epoch draw per node.
 
+The second sub-version 3 commit is 017e70376489251e18564c0abce7e466e606c8b3 (pushed 15:10 UTC's preceding hour, pre-push gate GREEN, CI run 37639406567 success). The crate suite at 017e7037 on box 2 (rc 0, 184 s): 64 lib + 7 derive + 4 mixer + 19 packs + 2 recheck + 7 scratch = 103 passed, 0 failed, 3 diagnostics ignored; the lib tests took 140.8 s against ddacfbd3's 41 s for the whole suite, because every class v4 draw in the tests now pays the 2^20 pass on its chosen candidate (2.2 s each); that is CI time, not node time. The static census at 017e7037 (box 2, 15:1x UTC, 4,096 chain-shaped seeds plus F8's p1 to p3, the draws in parallel over the box's cores since the ratio pass makes the serial run a four-hour job): 4,099 programs, 0 lossy-sourced load sites of 65,584 (57,322 inject, 8,262 bijective), 0 exhaustions; the accepted attempt 1,297 at attempt 0, 899, 609, 416, 298, 197, 125, 92, 54, 46, 21, 14, 13, 9, 6, 0, 2, 1 (mean 2.086, max 17) against ddacfbd3's 1,328, 917, 622, 409, 284, ... (mean 1.998, max 17): the ratio refuses about 4 percent of the candidates that pass every other test, one more attempt on about one seed in twelve; the devnet epoch-0 seed at attempt 1, id a785001687d8688a; F8's p2 at attempt 5, p3 at attempt 1. The attack-pass lane's class check of ddacfbd3's shadow-executed verdicts against 8bdcbdd8 (598,678 chain-shaped seeds): 11,990 (2.0 percent) accept at a different attempt, 0 exhausted, max attempt 32; on 017e7037 the pairing holds (the devnet epoch-0 program draws as a785001687d8688a) and its 64-seed gate at 2^24 and 10^6 exhaustion count were running at 15:1x UTC (finish about 16:05 UTC).

 Owed (recorded, not run, by the project lead's word): G2 (the CPU verifier on 1,024 hashes per card) on the amended stream; G3 (the Metal fuzz, edge, stats and determinism runs) on the amended stream; the hash-rate ladder re-measure on the M5 Max and the RTX 5090 (the amendment changes the base program's source draws, not the op mix or the load count, so the latency-bound rows of `docs/analysis/latency-shadow-2026-10-06.md` are expected to hold within their spread; unmeasured); AMD (the RX 9070 XT, PC 1); the 2019-class verifier core (O-1.14); F8's phase E (the 64-seed dynamic census) on the amended stream, which is the attack-pass lane's and the test of the per-op table. The row reads FIXED-AND-PASSED only after phase E passes against the amended class.
