GET /rbac/my/permissions returns role-derived grants only, so the backend's is_admin bypass is invisible to client-side gates. Record the gap, why it fails closed, and what to inspect first. Signed-off-by: Ahmad Al Tamimi <altamimi.dev@gmail.com>

hasPermission, the single symbol every client-side gate resolves to: the permission list comes fromGET /rbac/my/permissions, which reflects role-derived grants only; the backend'sis_adminbypass is invisible to the client. A DBis_adminuser without the wildcard role fails the gates even though the API would serve the data. The note spells out that the gap fails closed, that the 403-based PermissionDenied layer cannot surface it (a fetch-gated card never fires the request), and what to check first when an admin is unexpectedly missing a card.Two decisions worth flagging:
hasPermissioncalls; the note lives at the one definition both resolve to. Easy to revisit once more gated cards land.get_user_permissions()reflect the effective permission set foris_adminusers) belongs in IBM/mcp-context-forge and is not filed here.
