codex-threadripper Wangnov

Here's a situation you might recognize: you switch model_provider in Codex, and suddenly your session list is empty. codex resume finds nothing. The Codex app shows a blank slate. Your sessions aren't gone. They're just filed under a different provider in Codex's SQLite state DB. Codex only shows threads that match the active provider, so anything created under a different one becomes effectively invisible. codex-threadripper fixes this by rewriting the model_provider field on every thread row in Codex's SQLite state DB and in the first line of each rollout JSONL to match whichever provider you have active right now. After that, codex resume, Codex.app, and app-server clients all see the full history — no matter how many times you've switched.
