Every 5 minutes, the brain checks each finding aged 30+ minutes. It compares the bias-adjusted realized move against thresholds:

• Hit — signed move ≥ +0.5% in expected direction → weight += +0.005
• Miss — signed move ≤ −0.5% in expected direction → weight += −0.005
• Flat — between ±0.5% → no change

Weights are clamped to [0.5, 1.6] and applied multiplicatively to future raw signal scores. After ~200 outcomes per symbol, the brain has built meaningful posterior weights. Every nudge is logged here.
