What
When a cloud session (Claude Code running on a remote machine instead of your own) is asked to change its Claude Code settings files, Claude now receives a message saying the session is not allowed to. The message says nothing was changed and that you need to make those changes on the named target yourself.
Claude Code can also now describe why something stopped, with phrases such as "when its call ended" and "at its time limit".
Why
Instead of a settings edit failing silently or partly, you get a plain refusal and know to make the change yourself.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is not clear which sessions or targets produce this refusal.
