Windows sandbox refusals now say why an exclusion did not apply

You'll notice
Useful3 Signal2
Windows

Windows strict sandbox refusals now explain that an exclusion needs an available permission prompt to apply.

What

On Windows in strict sandbox mode, a refused command used to give one message regardless of cause. There are now two: the existing one for an exclusion that matched only part of the command, and a new one explaining that an exclusion only exempts a command when a permission prompt could approve running it unsandboxed, and no such prompt is available here.

Details
  • Both paths still refuse the command with the windows_policy_refusal outcome.
  • Applies only on Windows, with sandboxing enabled in settings, the platform in the enabled list, and strict sandbox mode configured.
Evidence

exclusions only exempt a command where a permission prompt can approve the unsandboxed run, and none is available here

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