Overview

Represents a named checkpoint attached to a state. A checkpoint pauses progression until its condition is satisfied. Unlike a guard (which is evaluated on the outgoing transition), a checkpoint is evaluated when attempting to ENTER or LEAVE a state —the workflow sits in a :waiting sub-status until the condition passes.
