An assistant that only talks is a good adviser. The moment it has to do something — read four hundred pages, compare three suppliers, fix a build at two in the morning — it needs hands, and hands are where trust gets spent. Until now the answer has been one model, one endless conversation and your keys in its pocket.
Our answer is many hands, each in a room of its own. A planner that writes the work down, sub-agents that start clean and report once, a cell around every one of them with the door shut until you open it, and a record of every step. Work you can delegate should be work you can read afterwards.
A cell is only as strong as the floor it stands on. Underneath every agent is a system built for exactly this, small, verified and the same everywhere, and that is the next chapter.
