[OAUTH-WG] Re: New Version Notification for draft-chen-oauth-agent-authz-use-cases-01.txt

Meiling,

Both issues confirmed.

I have proposed use-case text posted to #18 and alignment framing to #17.

- Issue #17: [Enhance UC5 with Cross-Draft Alignment](https://github.com/Maisy-ML/Agent-Authorization-Use-Cases/issues/17)

- Issue #18: [Add New Use Case for Cross-Organizational Delegation](https://github.com/Maisy-ML/Agent-Authorization-Use-Cases/issues/18)

Discussion welcome in either place.

During the session you referenced a prior list discussion of the cold-start scenario; in case it helps the record, that framing aligns with requirement R2 of draft-reece-wimse-cross-org-delegation-00 (cross-organizational verification without an interaction-specific prior arrangement), which I also applied in my July 20 note on the cross-domain transaction token thread. Your UC5 gap statement, no universal secure protocol for scoped, revocable access in a zero-trust, no-pre-channel initialization, is a very good articulation of it, and I would be glad to see it survive into whatever this document becomes.

>>> Second, an offer. UC5 as drafted covers the case where the service side lacks authorization infrastructure entirely. There is a companion case that I believe belongs alongside it: both sides have full trust infrastructure, the agent's organization and the service's organization each operate their own, and there is still no pre-authorization channel between them because they have never interacted. This is the ordinary condition of cross-organizational agent delegation, and its requirements are stricter in some dimensions (the service must be able to verify delegated, attenuated authority from another organization, potentially without a runtime callback to it) and looser in others. I would be happy to contribute that use case in your document's format, along with a mapping of the -01 gaps to the R1-R9 requirement set from the draft above, as review input rather than as competing structure. I also have a couple of small terminology notes, including one on the classical confused-deputy framing in UC3, that I will send separately so they do not clutter this thread.
