  "textContent": "I think I found a serious Codex issue that started after today’s update.\n\nWhat I see:\n\n  * Existing threads still work reasonably well.\n  * New threads are the problem.\n  * A brand-new Codex chat/thread does not start clean.\n  * It already shows around 40k input tokens immediately, even for a tiny prompt like `ping`.\n  * After only a few normal messages, the thread gets very heavy very quickly.\n\n\n\nI reproduced this on:\n\n  * my main Mac\n  * a second laptop\n  * both with different Codex versions / profiles\n\n\n\nSo this does not look like a single-machine issue.\n\nMy current suspicion:\n\n  * new threads are inheriting hidden context / workspace state\n  * or there is a Codex startup / workspace mapping regression after the latest update\n\n\n\nQuestion:\nIs anyone else seeing new Codex threads start with a huge hidden token baseline after the update?",
