Core concepts
Simulations
Run one Simulator with isolated and repeatable state.
A Simulation is a runtime instance of one ready Simulator.
It has isolated state, a virtual clock, and a data-plane endpoint.
The seed and clock start pin injected randomness and virtual time.
Use the same Simulator revision and inputs when you need repeatable behavior.
The create response includes a data-plane token once.
List and get operations never return that token again.
Fork a running Simulation to explore another path without changing the source.
You can fork the current head or a recorded step.
Use the API reference for exact Simulation routes and schemas.
