[BUG] All kinds of problems during last night's session
Preflight Checklist
- [x] I have searched existing issues and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code
What's Wrong?
The concrete items worth listing, from this transcript: reasoning shown as if addressed to you ("What I need next, privately"); a Cyrillic identifier generated in Swift source; three wrong diagnoses of the identical previews before the log line that answered it was read; generalising from five log lines; and a test report on a binary that hadn't been rebuilt. The timestamps and the quotes are all in the transcript.
What Should Happen?
I don't need to see internal dialog. I am talking in English; I should not see Cyrillic. I should not have to point out obvious misdiagnoses and tell Claude how to diagnose.
