Every TUI config-editor save regenerates the TOML through CorrexConfigWriter, whose [router.narration] section never wrote model_id — one save and narration silently fell back to the main model, queueing every narration behind slow 9B inferences (live QA: approval narrations arrived minutes late, after the workflow had already failed). The writer now persists it and the field is editable in the TUI (blank clears it).
