Summary: This draft is well written and clearly defines COSE header parameters for representing a payload as a hash (“hash envelope”). The mechanism aligns with COSE conventions and is appropriate for Standards Track publication.

Major issues: 
 - it would be nice to clarify why COSE_Encrypt is excluded and whether future extensions are possible.
 - Should clarify whether the “payload hash” is always detached or may coexist with the actual payload.

Minor issues:

Nits/editorial comments:
 - typos (“decicde” → “decide”)
