Target stability
We want the stack to live between 0.82 and 0.93. Below that, the field gets loose and noisy. Above that, it becomes too rigid and stops adapting. The gravity well is designed to hold the center without freezing the shell.
Pulse count
center pulses27
Each pulse corresponds to one local propagation state in the center kernel.
What the well does
The center is no longer a static anchor. It breathes as a 27-step attractor: pulling unstable branches inward, releasing coherent branches outward, then repeating. That makes it less brittle than a fixed center.
