What
Claude Code keeps a sync journal to track certain state. A new runtime assertion now throws an error when a journal note carries a chain of data that its reader would otherwise drop, such as entries out of order, a malformed link, or a carrier type this build doesn't know how to write.
Why
This turns a case that used to fail silently, by quietly discarding data, into a visible error, making problems in sync journal data easier to catch instead of going unnoticed.
