What
When Claude Code updates plugins, it lists which marketplaces failed or were refused and which plugins failed. Those names now go through a formatting step before they are shown, instead of appearing exactly as stored. Which formatting is used depends on the situation.
Why
In practice, the names you see in an update summary may not match the raw names exactly, possibly when the output is going somewhere other than your terminal.
