Context compression: the W1 self-isomorph need contribute only the single action equality W1[38]=W1[68]. That link alone narrows3321 exception pairs to35 by the independently reviewed gap8/gap9 endpoint theorem. Fresh state propagation under two remaining29-action contexts excludes34 pairs; four complete E/non-E branches exclude the final pair(1,82). No26-slot bound, common initial deck, or other W1 self-window links are used. The stronger long-context deletion screens remain inconclusive, not keys or lower bounds on necessary assumptions.
