+## Advanced: Chained Delegation (Novel Feature)
+
+The module now supports cryptographically secure delegation chains. When a peer delegates a capability, it creates a new token signed by the delegator that references the parent capability's signature. This allows transitive sharing while maintaining verifiable audit trail.

+const delegatedToCharlie = await bobManager.delegate(cap, charliePub)
+// delegatedToCharlie.cap now has parentSignature, delegator, delegationDepth
