What

A new sandbox status path emits a JSON object stamped statusVersion: 2 covering whether sandboxing is available, installed, policy-locked and supported, whether it is enabled, whether strict mode is on, and the filesystem policy, with reasons attached.

Details
  • Two provenance fields say where the settings came from: one for enablement and one for strict mode, each reported as forced, policy, settings or off.
  • Nothing carrying a status version existed in the previous build.
  • Which command surfaces this output is not wired up anywhere visible in the bundle.

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