Phase 63 · the localized autonomous doorway · AT-0581 → AT-0594

The first try woke the whole universe. The second one didn't.

Seed 581. We attacked the exact integration point Phase 62 named: the same autonomous activator / recovery law, plus local address guidance, plus the moving doorway, as one object. The first integrated attempt failed by reverting to a global avalanche — every size from N = 128 to N = 2,048 reached the destination, and every one of them lit exactly N nodes to do it, with activity scaling as N^0.93. So we tightened the rule into a gated catalytic doorway: base dynamics subcritical and decaying everywhere, catalytic drive admitted only at the locally designated next hop, and the same autonomous recovery law closing behind. Success 1.000 at every size, arrival 7.275 → 13.775 ticks, peak simultaneous activation 11 → 19, activity proxy 360.876 → 892.860. Finite-size exponents 0.240, 0.205 and 0.341. Both attempts are published here at the same size.
