Understanding the model

You don't need to understand any of this to use Lab. But if you want to know how the engine works — or to argue with one of its predictions — start here.

In this section

• How a simulation works — inputs, the receptor graph, signal traces
• Baselines and couplings — what the model assumes vs. what you set
• Confidence levels — how to read evidence strength
• When the model refuses — and why that's the feature, not the bug
