Lab mode — the red controls (the Verlet chain)

The chain is stable while its Courant number k·dt² stays at or under 1 — the bound the engine derives from each note and checks when a patch loads. Force it to 1.05: with the gate on, the engine refuses the patch and says why; bypass the gate and the shortest wave grows by itself until the lab catches it.
