Unclear The finding does not say what sets this flag or when.

What

A new internal flag, keepSessionMessagesCache, starts off (false) and has a setter that can switch it on. While it is on, the step that clears the stored copy of the session's messages, clearSessionMessagesCache, does nothing.

Why

This lets some part of Claude Code keep the stored messages around at times when they would otherwise be thrown away.
