What

When Claude Code falls back from one model to another, the event it logs now includes an originalModelName field with the human-readable name of the model that was switched away from, in addition to the existing originalModel ID field.

Why

This makes logs of model fallback events easier to read, since they now show a recognizable name rather than only an internal model ID.
