The issue names no implementation files, tests, or entry points. Start by reading the linked SPARCd Personas & User Stories wiki page and the planning notes to clarify the collection and ownership requirements. Done is not defined beyond ensuring collections have valid owners, so the implementation scope and acceptance checks need to be established first.
