The shared-operand rule (or-then-xor, or-then-sub, xor-then-or on one operand is a mask) in the draw's source rule and in the acceptance's (a') pass: p23's chain attempt 1 (id d65122675f16a1c7) now draws site 7 from r5 and passes. Rule (c''): over 4,096 units (2^20 evaluations per site, the shadow executed) every load site's distinct word indices against the uniform expectation on its window must reach 0.98, the last test of the chosen candidate; the floor sits 0.015 from the clean minimum (0.9960) and from the strong failing maximum (p56 0.9654). The staged 2^24 pass was not taken: at 2^24 the clean p44 and p52 (0.9612, 0.9613) read the weak four's value (0.9181 to 0.9630), so no 2^24 floor separates them. Open tail: p4, p8, p10, p34 (0.9927 to 0.9963 at 2^20), unattributed and chased. The (B) bound stays unwired. The test class_v4_distinct_ratio_rejects_the_low_entropy_band pins p15 (attempt 3), p18 (2), p19 (0), p56 (2) refused and p23's attempt 1 passing, its r6 variant refused by (a') and by the ratio (0.836). The stream is unchanged: re-export diff 0 on the eight packs, id a785001687d8688a, PROGRAM_SUBVERSION_V4 stays 3, fingerprints and zip sha256 stand. Cost: one 2^20 pass per chosen candidate, 2.1 to 2.2 s on one box-2 core.
