Salt & butter as cross-cutting foundation systems (salt-type × timing
matrix, butter state machine closing the whip→butter loop), P2 FIRE
(steak: season/cook/rest/cut/pair), P3 eggs & air (whisk shear, poach
vortex, two-layer set field), P4 the pass (composition, swoosh, dosing
danger), P5 service. Build model: parallel opus agents in worktree
lanes, reviewer holds the browser, harness numbers gate every merge.
