Thanks, this is exactly the boundary I was trying to validate.

The split you describe makes sense to me:

- LangGraph interrupt/request\_approval handles the agent-side pause/resume
- Approval Hub provides the reviewer surface, routing, notification, and approval state
- an external policy gate can normalize action intent, policy decision, and audit/receipt semantics across frameworks

The part I’m especially interested in is the handoff between the approval dashboard and the policy boundary.

For example, in a cross-framework setup, I’d want the reviewer decision to bind to a stable action intent/hash, not only to a human-readable action\_description. That way the system can later prove:

1. what the agent intended to do,
2. what the reviewer approved/rejected,
3. whether the eventual execution matched the approved intent,
4. and where the decision/receipt lives for audit.

So Approval Hub could be the HITL surface, while an external gate provides the policy/receipt layer underneath it.

Curious if your API already exposes a stable approval/request ID and enough metadata to bind the reviewer decision to an external action envelope?
