Mentor Studio
Speak the scene (90–180s): where we are, the live project, stakeholders, what good looks like, what will get someone hurt. Typing is the fallback. Engine assigns a scene template and proposes hotspots — mentors compose, then publish.
Auth: mentor / host only for publish & kill-switch. Workers cannot publish scenes. Drop real 180 plates in composer after generate — do not relabel 180 as 360.
