Claude Code interrupts itself after long "churning" without user input

What's Wrong?

Claude Code spontaneously interrupts its own response after churning for ~40 seconds. The "Interrupted · What should Claude do instead?" message appears without any user action (no Escape key pressed, no hooks
configured).

What Should Happen?

The model continues generating until it produces a response.
