What
Claude Code saves each session as a transcript file, adding one line at a time. It now:
- Forces what has been written onto the disk before adding more, instead of leaving it waiting in memory.
- Keeps track of lines not yet safely on disk.
- Starts a new line when the file ends partway through a line, so a half-written line does not damage the next one.
- Logs an error when forcing the file onto disk fails.
Why
Transcripts are more likely to survive a crash or a full disk intact.
