// Synchronous calls other systems make to access about Organizations and identities. Rights are read by every
// system from its own cached copy of memberships, fed by the events of access; this service bootstraps and
// repairs that copy, and lets farm mint the identity of a farm sync client.
// Callers: every system (StreamSnapshot, at start-up or after a gap in the events; req 5, 8),
// farm (RegisterServiceAccount from its backend when an enrolment code is redeemed; DisableServiceAccount from its
// backend when a sync client is retired or reinstalled, and from its sweeper when it retries a disable the backend
// could not finish; req 67, 1.*.2).
// The callers listed are authentication only (decided 2026-11-11): each RPC below names who may call it and what
// it sees, and refuses anyone else with PERMISSION_DENIED.
// Deadline: StreamSnapshot 60 s, RegisterServiceAccount 5 s, DisableServiceAccount 5 s.
// x-moonitoring-callers: farm, moochat, grant, releases, ai-model-platform, ai-gateway, news
// x-moonitoring-requirements: 5, 8, 6, 1.*.2, 67
