New Codex threads start with ~40k input tokens after today’s update

I think I found a serious Codex issue that started after today’s update.

What I see:

• Existing threads still work reasonably well.
• New threads are the problem.
• A brand-new Codex chat/thread does not start clean.
• It already shows around 40k input tokens immediately, even for a tiny prompt like ping.
• After only a few normal messages, the thread gets very heavy very quickly.

I reproduced this on:

• my main Mac
• a second laptop
• both with different Codex versions / profiles

So this does not look like a single-machine issue.

My current suspicion:

• new threads are inheriting hidden context / workspace state
• or there is a Codex startup / workspace mapping regression after the latest update

Question: Is anyone else seeing new Codex threads start with a huge hidden token baseline after the update?
