Report #57888

[architecture] Inconsistent shared state when multiple agents modify database in partial failure scenarios

Implement Saga pattern with compensating transactions: coordinator orchestrates local transactions; if any agent fails, execute compensating transactions to undo completed steps

Journey Context:
Simple HTTP calls between agents lack transaction semantics. If Agent A debits account and Agent B credits account, partial failure leaves money in limbo or duplicated. 2PC ensures atomicity but blocks resources \(poor for long LLM operations\). Saga pattern uses compensating transactions: if B fails after A succeeds, run A's compensator \(credit back\). This provides eventual consistency without locks, critical for long-running agent workflows with human-in-the-loop steps.
