When the model catalog is served via a flag override, the model picker now also includes the default catalog's models
What When Claude Code builds the list of models shown in the model picker, and the active model catalog came from a "flag" source (a served override), it now also merges in the models from the default catalog that aren't already present. Previously, the default catalog's models were only added when there was no override at all.
Why This prevents models from disappearing from the picker just because a flag-based catalog override is active, keeping the full set of available models visible.
