Unclear What the replacement routine does differently is not known.

What

When you switch models, Claude Code prepares some work in advance. It now does this with a different routine than before, and it no longer labels that step as coming from a model switch.

Why

This affects how cached work is prepared when you change models in the middle of a conversation.
