A persistent social collective agent requires an ongoing constituency relationship through recognition, contribution, governance, responsibility, or material dependence; affected outsiders create additional legitimacy claims.
Claim
A socially persistent collective agent is sustained by more than audience attention or account count. Some continuing constituency must recognize it, contribute to it, govern or rely on it, hold it responsible, or become materially dependent on its actions. Those relationships supply continuity, knowledge, legitimacy claims, and real consequences, but they need not all belong to the same people or carry equal authority. The agent may also affect nonparticipants and future people who cannot join its current procedures; their exposure creates claims that current membership cannot erase. This hypothesis assumes constituency relationships and material dependence can be observed rather than merely asserted. It does not imply that popularity creates agency, that users represent humanity, or that every affected person must vote. Architecturally, measure contribution quality, independence, retention, authority distribution, responsibility, dependence, and affected-party coverage rather than treating raw participation as intelligence or legitimacy.
