ChatGPT/Codex desktop app 26.826.11250 on Windows.
Chats created on Aug 26–27 disappear after restarting the app. Archived chats are empty. The old sessions folder and session_index.jsonl stopped updating on Aug 22, while thread_history_1.sqlite and its WAL files continue updating.
config.toml has no history override, and diagnostics reports healthy dependencies. The built-in /feedback upload also fails.

This appears to be a thread-history migration, indexing, or synchronization problem.
