Unclear The finding doesn't say whether the actual wording shown to users changed, only that it now routes through a shared builder.
What
When you give an artifact tool a file_path whose content type isn't recognized or servable, the error message is now built from a shared message helper instead of its own separate text.
Why
This is an internal cleanup so the unservable-file error stays consistent wherever file_path is used, rather than drifting between separately maintained copies.
