✓ Portable graph bundle live · download bundle · merged state

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

Recent DESI baryon acoustic oscillation measurements combined with cosmological surveys indicate a preference for dynamic, time-evolving dark energy rather than constant Lambda, potentially allowing string theory to escape the de Sitter swampland.

C2weakest assumption

That the apparent preference for evolving dark energy in DESI data reflects true cosmology rather than unaccounted systematics or alternative explanations within Lambda CDM.

C3one line summary

DESI data indicating evolving dark energy may allow string theory to describe observed universes without violating swampland constraints on constant dark energy.
