-Routed catalog entries also get their GPT-5 identity rewritten to the real upstream model name.
+The cloned catalog `base_instructions` identity line is rewritten to the real upstream model name
+as static catalog metadata. Runtime request identity is handled separately: routed adapters replace
+Codex's live GPT-5 identity line with a model-agnostic coding-agent introduction.
+When unique, their default picker label is the final segment of the native model id, so provider
+namespaces do not hide the model name in narrow pickers. Basename collisions retain enough native
+route context to distinguish the rows; if the same native id comes from multiple providers, the
+provider is shown too. The full catalog slug remains in the description. Configure a custom display
+name when the route itself matters visually (for example, `Claude Opus 5 (TeamClaude)`); custom
+names continue to take precedence.
 Reasoning controls come from provider/model metadata across Codex's `low | medium | high | xhigh |
 max | ultra` ladder; unsupported values are mapped or clamped before the upstream request.
