Past a capacity threshold the brain takes over. A greedy brain that edits the tool it thinks is worst can lock in a worse limb than blind selection keeps. This is a synthetic evolutionary simulation, not a user study and not a test of a real language model. The controller is a small lookup table. Code, protocol, and the raw series: dylanler/harness-vs-brain.
