The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The SIC can cleanly distinguish critical phases from extended and localized ones, as well as mobility-edge and other critical scenarios, through their distinct steady-state profiles, initial-site sensitivities and the presence of subregion echoes.

C2weakest assumption

That the observed spatial heterogeneity, stepwise SIC ramps, and subregion echoes arise specifically from IDZ-induced fragmentation and the quasiparticle reflection picture rather than from numerical artifacts, finite-size effects, or model-specific details.

C3one line summary

Subsystem information capacity distinguishes critical phases in quasiperiodic systems by revealing spatial fragmentation, stepwise ramps in steady state, and subregion echoes whose periods scale with subregion size, linked to incommensurately distributed zeros.
