What

The input used to decide permissions and model routing now carries the session's proactivity level alongside whether plan mode is required, the permission mode and the session effort setting.

Details
  • Passed at both call sites that build this decision input.
  • Unconditional; the value comes from your existing proactivity settings.
Evidence

proactivityLevel: u.proactivityLevel
