What
The edit and write confirmation dialogs now check whether the tool message they are about to render was withheld, and show a dedicated fallback in place of the diff. They separately notice when the raw input differs from its redacted form.
Details
The detection runs unconditionally; no flag turns it on.
Evidence
"withheld"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
