What
When Claude is driving a Mac app and a save sheet is open, several actions are now refused: putting a path or a shell-startup, ssh or launch-agent file name in the file-name box, pressing Return in the Go-to-Folder box, dragging or holding a press while the sheet is up, and typing into a window that is editing a protected document.
Details
All refusals report save_panel_restricted, a reason code that does not exist in the previous build.
Return in Go-to-Folder is refused as unverifiable, since the destination cannot be checked before it commits.
Navigation shortcuts still work in a window editing a protected document; only text entry is blocked.
The checks run on macOS and depend on the host being able to inspect the open sheet and the document being edited.
Evidence
save_panel_restricted
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
