fix(cliproxy): preserve saved codex model selections

@@ -59,7 +59,7 @@ All major modularization work is complete. The codebase evolved from monolithic
 - **2026-03-17**: Deprecated user-facing GLMT discovery across CLI help, completions, presets, and docs. Existing `glmt` profiles now run through a compatibility path that normalizes legacy proxy settings to the direct GLM endpoint.
 - **#748**: API profile creation now keeps provider selection compact by collapsing advanced presets behind an explicit toggle, shrinking chooser cards so the form fields stay visually primary, and giving `llama.cpp` a dedicated provider logo.
 - **#744**: API profile creation now keeps featured providers in a horizontal rail with scroll fallback, moves Anthropic Direct API to the end, reuses the shared Claude logo, and separates the custom-endpoint entry point from advanced template discovery.
-- **#724**: Codex startup is now free-plan safe. CCS defaults new Codex sessions to a cross-plan model and auto-repairs stale paid-only Codex defaults when the active account is on the free plan.
+- **#724**: Codex startup is now free-plan safe. CCS defaults new Codex sessions to a cross-plan model and uses runtime fallback handling for unsupported paid-only models without rewriting the saved dashboard settings.
 - **#737**: Dashboard model pickers in Cursor, Copilot, and CLIProxy now use a searchable combobox with autofocus and explicit no-results states for large model catalogs.
 - **#736**: `ccs config` now supports explicit dashboard bind hosts via `--host`, and surfaces remote-access warnings plus reachable URLs when the effective bind is non-loopback.
