Roles are stored in the new resource:action format and any legacy keys are
converted once at startup by the RBAC v2 DB migration (migrate_rbac_v2), so
the permission engine no longer needs to resolve legacy codes on every check.
- get_user_permissions: store role permission codes as-is (no dual add).
- has_permission: match new-format codes only; drop resolve_permission and the
dotted-code fallbacks.
- Remove now-unused resolve_permission import in middleware.
- LEGACY_PERMISSION_MAP / convert_* are retained as one-shot DB-migration
utilities (upgrade path), not a runtime bridge.
- Tests: adapt fixtures to new-format role permissions; assert legacy keys are
no longer honored at request time.
