What

The sandbox status view now tells you if HTTPS interception is actually set up, and what to do when it isn't.

Details
  • Adds a "TLS inspection CA:" row rendering either "trusted" or "not trusted".
  • When the untrusted CA is the managed one, the row suggests "· run /sandbox install".
  • Otherwise it advises "· ask your administrator to trust the configured sandbox CA — see https://code.claude.com/docs/en/sandboxing".
  • Only computed when the sandbox TLS-terminate configuration is present; on Windows this means the CA source is not "unavailable". Otherwise the trust field is null and the row is hidden entirely.
