Curiosity, recall, and confidence What makes an idea stick?

Curiosity can open a window for memory, but confidence, recall, comprehension, and the urge to return are not the same thing.

 Confidence, scores, timing, and prediction What did the signal actually measure?

 Ideas, implementation, and visible proof Did the improvement reach the person using it?

A plausible system is not yet a working product. These build notes follow each claim to the layer a reader can actually see or hear.
