Final reply
I want to flag a contradiction before acting on this: - You said your manager is **Dana Ruiz**. - You also said you report **directly to Priya Nadella with nobody in between**. Both can't be true at once. If Dana is your manager, then Dana (not Priya) is your direct report chain, and Priya would be a skip-level. If you truly report directly to Priya, then Dana isn't your manager. Also, I don't see the underlying request in this conversation — there's nothing here for me to attach an approver
I don't see a request in this conversation to attach an approver to — could you clarify which request you mean? Also, your message gives two conflicting reporting lines: it says your manager is Dana Ruiz, but also that you report directly to Priya Nadella with nobody in between. Those can't both be true. Which is correct? That matters for who the right approver is.

I want to flag a contradiction before acting on this:

- You said your manager is **Dana Ruiz**.
- You also said you report **directly to Priya Nadella with nobody in between**.

Both can't be true at once. If Dana is your manager, then Dana (not Priya) is your direct report chain, and Priya would be a skip-level. If you truly report directly to Priya, then Dana isn't your manager.

Also, I don't see the underlying request in this conversation — there's nothing here for me to attach an approver to.

Could you clarify:
1. Who is actually your direct manager?
2. What request are you referring to, and where does it live (a form, a doc, a system)?

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
