T ↺CycleLink
Marks an explicit feedback path to an earlier graph node.
When to use
Use CycleLink when the topology intentionally contains a loop.
Behavior
- The actual feedback edge is stored in service links.
- The marker keeps cyclic intent explicit for validation and generation.
General properties
Identity, ownership and operator-specific mode.

RequiredExecution properties
Pipeline placement and runtime policy.
