Report #39756

[architecture] Partial failures in multi-agent workflows leave system in inconsistent state \(e.g., inventory deducted but payment failed\)

Implement Saga pattern: each agent action has a compensating transaction; use a saga orchestrator to track state; on failure, execute compensations in reverse order to maintain eventual consistency

Journey Context:
Developers use simple try-catch blocks or distributed two-phase commit \(2PC\), but 2PC blocks resources and doesn't scale across heterogeneous agents. The alternative is 'hope for the best' with manual reconciliation jobs. The right call is the Saga pattern \(choreography or orchestration\) where each step has a defined compensating action \(e.g., 'reserve inventory' compensates with 'release inventory'\). If Agent 2 fails, the orchestrator tells Agent 1 to run its compensation. Tradeoff: Complexity of writing compensating transactions \(not all actions are undoable—payments may require refunds, not voids\) and debugging distributed sagas is cognitively hard, but necessary for correctness across independent agents without global locks.
