Why the May 2026 state-machine story is not finite automata becoming fashionable again, but durable execution becoming the reliability boundary for agents, workflow engines, and document-heavy product systems.

Outcome: Reader can distinguish statechart formalism from durable execution, pick the right runtime for agents and long-running workflows, and model document-heavy product lifecycles with explicit states, transitions, checkpoints, and ownership.

Why an agent harness re-fired a half-finished tool after a worker restart, the four Python libraries that solve different parts of the problem, and a concrete contribution roadmap for xstate-python.

Outcome: Reader can map a Python workflow to the right state-machine library, distinguish statechart formalism from durable execution, and know where to start contributing to xstate-python with file paths and named missing features.
