What

Denials are now reported in headless runs that have no prompt surface, not just when a prompt was shown.

Details
  • emission was factored into a reusable emitPermissionDenied
  • the no-transport path now emits it for non-allow decisions too
  • the schema description was rewritten to state that with bare -p, or SDK query() without canUseTool, 'ask' decisions are terminal and are also reported
  • the event is documented as best-effort advisory
Evidence

Best-effort advisory: in rare races a denial can book without a frame or a frame can lack a booking twin

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
