Instrument an open model during a forced collision and find the internal pattern that separates a far-and-good idea from far-and-junk, the activation signature of genuine bisociation.
Probe activations across layers during forced generation; correlate internal states with the far-and-good outcome; isolate the moment two frames fuse.
A mechanistic account of insight is the deepest moat there is, and a contribution a frontier lab would want.
