Transition Guards and Repair Routing
In StateM runbooks, permitted transition edges between states can be augmented with guards and edge-specific transfer hooks. These edge-level conditions dynamically select between alternative outgoing paths based on runtime information, such as exit check results, execution receipts, recorded failure counts, external readiness, or operator blocking status.
For instance, following a verification phase, an edge guard routes execution to a configured repair state if pre-commit checks fail, advances to handoff once sufficient objective evidence has accumulated, or enters a pause state when human approval or external services are pending. By encoding recovery pathways directly onto graph transitions, repair routing becomes an explicit, enforceable structural contract rather than an implicit instruction the agent must remember.
