A load whose source was last written by or, mul or mulhi makes a cross-hash hot set
7 October 2026The item histogram of class v4 over 2^26 nonces is not uniform: the top 0.1 percent of items take 0.520 percent of reads against 0.115 for a uniform control (4.05x), one item takes 78,479 reads (153x the mean), and site 15 feeds 6.37 percent of its reads into that top 0.1 percent in every iteration."

The eighth live hot set (seed 122960, id 4be7393ab6c84802, the deepest found: X_f +0.111 percent, 1.54x the window model, its hottest item at 475,616 reads from an all-ones source) reads minimum site 12 at 0.9824 at the acceptance's own 2^20 sample (live 0.9822), refused by class v5's (c''') floor at 0.995; so the floor refuses nine of nine live hot sets by X_f at or above f found in the tail of 269,250 accepted programs (minimum sites 0.9809 to 0.9919; the ninth, seed 228763 from a non-saturated source, at 0.9809 on 8 October 2026) against 0 hot sets in 20 random programs; what it misses stays the three mild shadow-block-written concentrations at 0.9992 to 0.9997 (Devnet 3's first program among them), about 1.0004x to a chip, the value-level test in the next class (22:41 local time; the logs under a repository file/ on branch adv-accept; the v5 design's section 14). The public sentence (the coordinator's wording, 7 October 2026, night; the count moved to nine at 01:13 local time on 8 October when the ninth live hot set, seed 228763 from a non-saturated source, read 0.9809 and was refused): nine of nine hot sets refused; the diffuse era-stride excess, bounded under 0.1 percent of a hash's reads per site, is not caught by the floor and is the next class's test. The reason, read by the in-house pass (adv-cache-2) and the class v5 lane together: the distinct-index count at 2^20 sees concentration on few word indices whatever their source, saturated or not (the hot sets put about 3 percent of a site's reads on 512 indices, so the ratio falls to 0.981 to 0.992; the final tally 9 of 9 live hot sets and both single-item programs refused, 7 clean-live programs refused among the 12 deepest, 3 mild residuals missed) and not a diffuse excess over the top 0.1 percent of items (16,384 items), which is what the era-stride low-bit law produces (13 of 27 drawn-era programs carry a site over 1.04x, 8 over 1.2x, worst 1.75x; 0 of 29 refused at the 2^20 sample, minimum sites 0.9965 to 1.0000); its chip value is about 1.0024x at the worst site read, under this row's bound by an order; the row for it is AP-F8-6. The RTX 5080 grid's knee is not in tonight; X37 keeps the 5080's stock premium only.The answer as first written
Correct as a fault, wrong as a null. The window layer (spec 01 1.13.1 as proposed, a repository file 1.4) moves the uniform null from 0.115 to 0.160 percent at the top 0.1 percent (1.39x, not 4.05x) and explains every per-site row of F8's attribution except site 15. Site 15's source r6 was last written by or r6, r4 (instruction 61, the load at 63), a non-injective op whose output bits are 1 with probability 3/4, so the all-ones source recurs with probability (3/4)^32 per read; the era map sends it to item 0xca5b92, F8's hottest item exactly, and F8's next seven items are exactly the seven one-zero-bit sources whose zero survives the window mask. The popcount model at the measured bias (p = 0.7585) predicts 77,348 all-ones reads against 78,479, and the program's top-0.1-percent share at 0.58 against 0.52. The acceptance rule's part (a) takes any write as a fresh source and part (c) counts saturation on final register values only, so the class of fault passes it: of 1,024 chain-shaped class v4 programs 96.6 percent carry a load whose source's last writer is or, mul or mulhi, 48.5 percent an or-sourced one (0.30 percent of all reads per site), 4.9 percent an or-of-or chain (p3's class: 72 percent of that site's reads, 4.6 percent of all reads, on 0.1 percent of items). The ceiling under rule (c)'s 120-of-128 floor is one site repeating its item in all 8 iterations, 6.25 percent of reads, a chip edge of at most 1.067x in 64 bytes of SRAM; the public claim's 2x margin stands, and the public line says "bounded", not "uniform" (a repository file sections 1 to 4).
