/**
 * v1 token scopes must intersect the owner's CURRENT role permissions
 * (GHSA-9697, codex round 2).
 *
 * Migration 081 documents effective permissions as the intersection of the
 * owner's role permissions and the token's scope flags. requireApiScope only
 * ever checked the scope half, so a token minted while its owner was
 * super_admin kept full write access after the owner was demoted to viewer —
 * userManagementService never touches api_tokens, so the token outlives the
 * demotion. Ownership scoping alone does not close this: the demoted owner
 * still *owns* their events.
