In a StateM runbook, directed edges between states can be augmented with edge guards and edge-specific transfer hooks. These conditions dynamically determine valid outgoing transitions based on check outcomes, execution receipts, prior failure counts, external readiness, or user-blocking statuses.

By embedding branching criteria directly on graph edges—such as routing to a designated repair state upon test failures or routing to handoff once sufficient evidence is validated—repair and continuation pathways become explicit structural guarantees in the runtime graph rather than implicit behavioral instructions that the language model must remember to invoke.
