Fixing Codex File Sync Crashes in Large Repos

Learn how Codex Desktop and CLI can drift out of sync with your real filesystem after rapid branch switches or workspace changes, and how to diagnose stale file state with /state and CODEX_SYNC_DEBUG. The episode also covers tuning watcher exclusions in .codex/config.toml to avoid file-watch crashes, resource exhaustion, and risky system-wide inotify tweaks.
