      "A durable orchestrator invokes three Lambda functions in sequence, passing each step's output as input to the next. The durable framework checkpoints after every `context.invoke()` call and if the orchestrator fails, it replays from the beginning but skips completed steps using stored results, ensuring no work is repeated."
