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

we show that this mechanism remains viable: after a supercooled transition, reheating can be sufficiently slow that the Universe enters an early matter-dominated era, during which even small overdensities grow and collapse into primordial black holes.

C2weakest assumption

Reheating after the supercooled transition is sufficiently slow to allow the Universe to enter an early matter-dominated era.

C3one line summary

Primordial black hole formation from slow first-order phase transitions remains viable if slow reheating after supercooling creates an early matter-dominated era allowing small overdensities to grow, producing black holes with large spins.
