SummaryThe article explains durable execution for long-horizon agents: runtimes persist external side effects, replay programs after crashes or network failures, skip completed steps, and reconstruct state. It separates runtime guarantees from harness design and examines multi-day workflows involving people and external systems.
Why it mattersIt gives architects a concrete model for assigning reliability guarantees between the runtime and the agent harness when building multi-day automations.
