Restate
Trace Restate durable-execution agents in Muster via OpenTelemetry — every step persisted, every span captured.
Restate is a durable-execution runtime that persists every step of an agent run so failures resume rather than restart. Muster captures Restate executions via OpenTelemetry, with the RestateTracer flattening agent spans under Restate's parent span for a unified trace view.

Each tool invocation becomes a durable step in Restate's journal — and a span in Muster. If a request fails, Restate resumes from the last completed step rather than restarting the agent.
