What probably matters to youSection of the release
What

Doctor gained a check that surfaces sandbox mask-credential warnings as individual issues with a concrete fix, instead of leaving them as a single stderr line at startup.

Details
  • runs only when sandboxing is enabled and a mask warning is present
  • splits the warning on " · " and turns each part into its own issue
  • covers empty injectHosts, masks degrading to deny on macOS, and TLS termination not being enabled
Evidence

TLS termination is never enabled in scrub-only mode

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