It is a property of six separate places, and each can become fail-open on its own:

  • missing rule returning allow;
  • recompute falling back to client-supplied values;
  • warm cache never re-checked against source;
  • blanket except;
  • legacy path that predates the gate, and non-atomic grant consumption.
