Start from the reported error text: `VirtualMessageList: itemKeys/messages length desync` in Claude Code 2.1.261 on win32, and search the codebase for `VirtualMessageList`, `itemKeys`, or the stack symbols if source maps are available. The issue does not include reproduction steps, so a first step is to reproduce or request the action that triggered it. Done means the desync cause is identified and the error no longer occurs for that scenario.
