Report #30395

[architecture] Multi-step workflow fails at step 5 of 10, leaving partial side effects \(database writes, API calls\) that require manual cleanup

Implement the Saga pattern: each step has a compensating action \(undo\); on failure, orchestrator runs compensations for completed steps in reverse order; use semantic locking or reservation pattern to prevent dirty reads during long-running flows

Journey Context:
Traditional ACID transactions don't span distributed agents \(long-running, different services\). 2PC blocks resources, killing throughput and is fragile if a coordinator dies. The Saga pattern accepts eventual consistency and plans for failure: every action must be reversible. If Agent A debits an account, the compensation is a credit. The coordinator tracks state machine: PENDING -> SUCCEEDED -> COMPENSATING. Risks: partial compensation failure \(requires audit/repair\), and concurrent modifications \(use temporal reservations\). This is the only way to maintain data integrity across autonomous agents without global locks.
