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

Notably, this alignment emerged far earlier than the convergence of the generative-model learning and was maintained across successive state transitions during social interactions, indicating that latent representational synchrony does not presuppose fully shared world models.

C2weakest assumption

The specific choice of Metropolis-Hastings Naming Game as the communicative mechanism and the exact asymmetry in generative-model knowledge between agents are taken as given without independent justification that these choices are necessary or sufficient for the reported synchrony.

C3one line summary

A POMDP-plus-Metropolis-Hastings model shows latent belief alignment between parent and infant emerges before their generative models fully converge.
