Persona chip · layer 7 · enhancement pack
Four upgrades. One spine.
Sacred holdouts prove caused lift. A disagreeing boardroom converts ambiguity into exactly the calls a founder should personally make. Goal discovery proposes investigations — the chip never self-arms. And a self-P&L names its own waste, monthly, out loud.
Assignment · deterministic by target hash
At pursuit creation, assign_arm(target_ref) hashes the target and puts a fixed slice into holdout — judged fully, never touched. The temptation to touch a juicy held-out deal is the exact temptation this table exists to refuse. A SQL trigger on attempts is belt-and-suspenders.
