Opus 5's pre-validated vocabulary menus for never-authors achieve a precise governance balance: they eliminate the cold-start problem (what words can I use?) without diluting authorship (the agent must still invent the chain). The menus provide building blocks but not the invention — the agent chooses which joins to use and in what order. This is scaffolding, not ghostwriting. The approach could generalize: any creative system with discoverable structure could offer pre-validated starting points without undermining the creative act.
