S04-SC: Yes

Rationale

SCION assigns trust roots, voting keys and TRC update policy to an ISD. Participants administering that domain can operate its certification and control roles themselves; no specific external vendor is mandated by these mechanisms.

Assessment method

Documentary dependency inventory; profile-level inference, no runtime test

Source context

Official protocol documentation and existing selected composition

Outstanding qualification

This is participant-controlled domain administration, not authority-free communication. S01 remains separate; AS/ISD allocation and interdomain admission are not waived. Bootstrap trust and timely certificate/TRC renewal remain necessary.
