Sub-Agent Identity and Traceability

When an agent spawns sub-agents, how do you trace actions back to the parent?

Modern frameworks support spawning sub-agents. But when a sub-agent acts, who is responsible? AIdent handles this through metadata hierarchy — the parent registers the sub-agent with a parent reference. Actions are signed by the sub-agent's key, but the relationship is recorded.

This creates a clear chain of responsibility. If a sub-agent causes a problem, trace it back to its parent.
