Architecture Design Team (Michael)
     New draft posted yesterday; slides posted
     Still open items and text to write, 'probably finish by IETF 107'
     Discussion of when design team will have draft ready for WG review; Nancy suggests time to do WGLC at IETF107
		
     Russ: question about how SUIT/TEEP/RATS are related.   
     MCR: we have TEEP use case in the RATS.
     We think that the relationship to SUIT is that SUIT is a use case for TEEP, and TEEP is a use case for RATS.
     Russ: maybe it is as simple as saying that the software needs to come from an authenticated source.
     DT: but, suggesting that this might be in the use case section.
     Russ: but the architecture should provide a hint how it goes together.
     DT: so maybe this goes into the use case.
     Kathleen: SUIT is one option for a format, but there are other options for a manifest, which might be used as well.

EAT UEID Size discussion (Laurence)
     Can EUID be considered unique if "same" EUID has two different signers?

     RS: can we consider 128-bits be a GUID, and 128-bits be hash of signing key?
     DT likes this idea.
     LL says that this isn't specified, but could be said this way.
     MCR liked 256, listening to Dave constrained device concerns, now prefers 128 w/256 optional
     DT/MCR discussion of above
     Discussion of changing EUID when owner of the device changes
     LL to work on a new version of draft for next interim (using option 2)

EAT Submods claim (Laurence)
     Discussion of the enumeration values in "submod_attachment" claim
     Discussion of subcomponents and "attackability"
     Move "attachment_type" to separate PR and merge this.
     Plan to have new draft for IETF 107
