Bug Description
I have to rewind to about 25%+ context remaining in order to compact conversation unless I let it run into auto-compact. I used to be able to compact as low as 0% remaining.

This is similar to https://github.com/anthropics/claude-code/issues/8881 but that issue doesn't have a lot of error logging and this may be a better bug to follow.
I have not run into this following the big UI update to CC. Can mark as closed and will file a new one if needed.
Will say this does happen mostly when I've ignored a request for a terminal command for too long. Like at a reproducible amount.
