Detailed Description

Provenance recorded next to every stochastic triangulation.

A resumable checkpoint couples the triangulation payload to the complete mutable transition-engine state, cumulative transition trace, and move statistics. Older checkpoints without that state remain readable snapshots but cannot be resumed. Payload-derived counts, time bounds, and fingerprints are reconciled with the serialized triangulation before publication. Callers remain responsible for supplying truthful run configuration and RNG provenance. The five input_* fields form one optional, all-or-none description of the initial artifact used to start a new transition run.
