No of course it’s unrealistic for them to hold the cache indefinitely and that’s not the point. You are keeping the session data yourself so you can continue even after cache expiry. The point I‘m making is that it made me very angry that without any announcement they changed behavior to strip the old thinking even when you have it in your session file. There is absolutely no reason to not ask the user about if they want this

And it’s part of a larger problem of unannounced changes it‘s just like when they introduced adaptive thinking to 4.6 a few weeks ago without notice.

Also they seem to be completely unaware that some users might only use Claude code because they are used to it not stripping thinking in contrast to codex.

Anyway I‘m happy that they saw it as a valid refund reason
