[architecture] Multi-agent pipeline fails at step 5 of 8 and must restart from scratch, wasting tokens and time

Persist every agent's output to a durable store at each step; design the orchestrator to resume from the last successful checkpoint rather than from the beginning.

Journey Context:
In multi-agent pipelines, failures are common — API rate limits, model errors, timeouts, validation failures. If Agent E fails and you must restart from Agent A, you waste all the tokens and time spent on A through D. The fix is to persist every inter-agent output to a durable store \(database, file system, message queue\) at each step, and design the orchestrator to resume from the last successful checkpoint. This is the event sourcing pattern applied to agent orchestration: each agent's output is an event that can be replayed. The tradeoff is storage cost and I/O latency at each step, but you gain resumability, auditability \(full trace of every agent's output\), and debuggability \(you can inspect any intermediate output to diagnose failures\).
