StateGuard maintains a last-in-first-out (LIFO) undo stack; each time a node produces an API side effect, the corresponding compensating action is pushed onto the stack, and rollback executes the compensating actions in reverse order.

UnverifiedStateGuard's @guarded_node decorator subjects node state output to pre-commit invariant validation before returning it to the graph executor; upon validation failure, it aborts the checkpoint write, restores state to pre-validation status, and triggers Saga compensating actions.68% similarUnverifiedImplementing the stack mechanism in code requires a pause-and-resume recursive resolution system and handling edge cases where effects are countered due to target invalidation (fizzle).62% similarUnverifiedThe Loop mechanism is similar to the retry-plus-state-recovery pattern in software engineering, handling network interruptions, environment crashes, or timeouts by persisting task state and continuing execution from checkpoints.62% similarUnverifiedNodes containing interrupts may restart from the beginning upon resumption; code before the Interrupt will execute again, and if side effects have already occurred they will be repeated, requiring idempotency protection with a business key or moving one-time side effects to a safe task boundary.61% similar
