Checked and Recoverable Transition Semantics
StateM implements a state transition model characterized as checked, logged, and recoverable rather than fully transactional. When advancing state via goto TARGET, the runtime delays committing the target state until all pre-commit checks and hooks succeed. If a failure occurs, execution remains halted in the source state and writes a failure record, allowing the agent to inspect and repair the deficiency.
However, because hook execution interacts with external tools and host processes, StateM cannot perform an automated ACID rollback of arbitrary external side effects. Instead, recovery relies on restoring durable StateM execution logs and executing configured, idempotent repair routines.
