If cloud changes arrive in a newer format, you're told to upgrade rather than to retry.
What's wrong with this entry?
If the cloud session sends its changes in a format this version cannot read, you now get an upgrade prompt instead of the generic retry message.
- The message reads "What Claude changed in the cloud was sent in a form this version of Claude Code cannot download; update Claude Code to receive it".
- Ordinary download and journal failures were demoted from info to debug, so they no longer appear as visible lines.

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