What
The temp-file writer gained a create-only mode that publishes via link plus unlink instead of rename.
Details
- In this mode an existing destination file is left intact and the write fails rather than overwriting.
- Rename remains the default publish path.
Evidence
create_only
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
