-- Deployment-global relay operator roster (Phase 2 admin auth: role-based).
--
-- This table tracks deployment-level principals (operators and moderators)
-- staffed via the admin API. Config-backed operators (RELAY_OPERATOR_PUBKEYS,
-- RELAY_OWNER_PUBKEY owner-fallback) are never seeded here — they are
-- authoritative in config and outrank any DB row.
--
-- Global (no community_id): operators span all tenants, so tenant-scoping
-- would be a misnomer. Registered in _operator_global_tables and in the
-- hardcoded parser list in crates/buzz-db/src/migration.rs.
