whats driving the hour cache? shouldnt people be able to have lunch, then come back and continue?

are you expecting claude code users to not attend meetings?

I think product-wise you might need a better story on who uses claude-code, when and why.

Same thing with session logs actually - i know folks who are definitely going to try to write a yearly RnD report and monthly timesheets based on text analysis of their claude code session files, and they're going to be incredibly unhappy when they find out its all been silently deleted
