So as the sender of the /send_join request, should we still ensure that the signed event is present when performing a restricted join, as it must be signed in this case?

What do you mean by present? Present when you get the room state?
As the joining server I think the important things to do are:
- Verify the signatures as with any event.
- Ensure this copy of the event is persisted locally and not the copy that was used to make the
/send_joincall.
I'd have to double check what synapse does to see if there's anything else though.

The signed event being returned in the event field of the response.

The signature needs to be checked (as is in the auth rules), Synapse does this @ https://github.com/matrix-org/synapse/blob/23740eaa3da94fbe2e25180376961979fc4e8cd3/synapse/federation/federation_base.py#L238-L259.
I'm still unsure if that's your question or not though.

Hrm. I think we need to clarify this a bit more. It just begs the question, "so when should the event be signed by the resident server".

Would linking back to restricted joins be enough?

I took another attempt at this, let me know what you think.
