The comment prefill fell back to the feed index — which counts pages and questions together — whenever the lazy page cache had no entry, so the ref pointed at the wrong page. Read the feed item map instead, which is built whole at boot with the true page and question numbers. And a leftover bare ref from an earlier open now gets replaced by the page in view; only a real typed draft survives. Claude-Session: https://claude.ai/code/session_01FryvSZ4bmGcpc7q13FNaCj
