Document that CRMFPopClient uses POP_NONE for ML-KEM enrollment requests (no Proof of Possession) and advise generating and submitting such requests from a trusted, authenticated environment. Add a cross reference from Server-Changes to the Tools-Changes note.

Merge Risk: 🔵 Low · up to 7e6dc

The release note can mislead users into believing ML-KEM requests always omit Proof of Possession, even when explicit POP options are supplied. Clarify that POP_NONE is the default before merging.

`POP_NONE` when generating an ML-KEM request (including requests used for
KRA key archival). The request therefore includes no Proof of Possession,
and the CA cannot verify that the requester owns the ML-KEM private key.

Describe POP_NONE as the default, not as an unconditional selection.

At Line 16, CRMFPopClient selects POP_NONE only when no POP option is specified. Explicit -q POP_SUCCESS and -q POP_FAIL take different branches and attempt POP processing. Therefore, the current wording can mislead users about the resulting request.

Use conditional wording such as “by default” and “with this default” for the no-POP statement.

Proposed wording
-`POP_NONE` when generating an ML-KEM request (including requests used for
+`POP_NONE` by default when no POP option is specified for an ML-KEM request
+(including requests used for
 KRA key archival). The request therefore includes no Proof of Possession,
