[BUG] Opus 4.7 replicating session inside of session

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

include "Opus 4.7 1M hangs at 'Concocting…' during skill prelude, process
respawns in a loop, HUD never stamps." Your shell wrapper is clean; your settings are clean; the dying piece is the model load itself.

What Should Happen?

should not replicate session chat inside of existing session chat.
