// Package role defines the tenant membership roles and the single permission
// matrix that authorizes console and management behavior.
// Package role defines the permission vocabulary that authorizes console and
// management behavior.
//
// Roles are stored in memberships.role. Authorization decisions must derive
// from Grants or Allows so that SQL role checks and Go checks cannot drift
// apart.
// Roles are rows in the roles table and their permissions live in
// role_permissions, so a tenant can define its own and authorization is
// resolved by the database rather than from a matrix held here. What belongs in
// this package is the closed set of permissions a role may be granted, plus the
// labels the console renders.

// constraint in migration 0006: a name that is not in both places cannot be
