 Verdict: the engine's draw 2a1d6caab4c24564 PASSES the sub-version 3 rule with the (c''') floor (every site clear of 0.98 and 0.995 at 0.99988, the largest 256-item bucket +6.25 sigma on one site, which the rule does not bound and the record's clean full-window sites read to +5.5, the worst free index bit 3.06 sigma, no site over 6 sigma) and the attempts census (256 of 256 chain-shaped seeds accepted inside two attempts, 0 exhausted, 0 (c''') refusals: the same 294 candidates and parts as the research pack's, since the census draws its own seeds under the pair's era and state). The research comparison reads the same on every line but the bucket (+5.25). The freeze's object on the chain's own seed is sound under the rule; the research pack's rows (census-packs.md section 7) are the same class on the genesis seed.

+## The window trace on the signing program (22:53 to 22:56 UK, build-4)
+
+The uniform tool (`tools/attack/v6-census/uniform`, with `--epoch-hex` added so one chain-drawn program is traced) on the engine's pair at 2^22 nonces, every load of the 32-site interleaved schedule through the interpreter's tracing probe on the closed form, beside the foldrw control (the same pair, no window; program 768497ac7a47599a). The tool prints the draw's id under the un-stamped generator byte (c3c7ce6d9df51c48 for the signing program); the seed bytes, class, era and attempt 0 are the CLI's, which stamps the same draw 2a1d6caab4c24564 at generator 6.
+
+| Program | Per-site distinct ratio (worst site; floors 0.98 and 0.995) | Top 0.1 percent item share | Flat control | Ratio to flat | Against the foldrw control |
+|---|---|---|---|---|---|
+| the signing program (2a1d6caab4c24564; 1,073,741,824 reads) | 1.00262 (site 7) | 0.001683 | 0.001447 | 1.1631x | 1.021x |
+| the foldrw control (768497ac7a47599a; 536,870,912 reads) | 1.00266 (site 13) | 0.001875 | 0.001646 | 1.1387x | |
+
+The window on the signing object reads as the class traces read (1.0026 per site, 1.015 to 1.032x of the control): uniform inside every window, the item-level share the era windows' with at most 2 percent on top.
