Designing Discipline for AI at WorkASSIST, PROMPT, and the Discipline of Human AuthorityOnce AI shapes decisions, informal judgment is no longer sufficient.This is Volume 3 of the AI at Work series. Its role is discipline.This book introduces two formal methods: ASSIST, which governs whether AI assistance is permitted at all and under what conditions, PROMPT, which governs how interaction must occur once assistance is authorized.Together, these methods do not optimize AI.They preserve decision ownership.The series progression is intentional: Volume 1 names the problem, Volume 2 explains how it becomes systemic, Volume 3 provides an enforceable structure, and the Companion Manual supports real-time application.This is a method book, not a position paper.Understanding it is not enough. Discipline must be designed.
