Write tool now refuses files covered by a Read deny rule

Files covered by a Read deny rule can no longer be written, not just edited.

What

A Read deny rule in your permission settings now blocks writes as well as edits. Attempting to write such a file fails with "File is covered by a Read deny rule in your permission settings and cannot be written." No flag involved; this applies to everyone on this build.

Details
  • The check runs twice: in the Write tool's permission pre-check, which returns errorCode: 13, and again at write time, which throws a file-state error
  • Both paths use the same new message
  • Previously only the Edit path checked deny rules, with a message ending "...cannot be edited."
Evidence

File is covered by a Read deny rule in your permission settings and cannot be written.

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