Start by reproducing the report on Windows Terminal with Claude Code 2.1.266, using the supplied Feedback ID and the VirtualMessageList length-desync error as the initial evidence. Trace whether the reported conversation-memory failure is associated with the expensive API calls; done means the desync and resulting loss of memory or repeated requests no longer occur.
