Descent model
Gradient descent across every layer — one probability, self-determined
01
Initialize
Weights start from layer reliability — a rough prediction, not random
02
Calculate loss
Brier vs won/lost, or the consensus of reliable layers when unlabeled
03
Calculate gradient
Slope of the error — which layers to trust more or less
04
Update weights
Step opposite the gradient. Repeat until the valley floor
Loss landscape
Hiking the valley
Fog metaphor from the algorithm: feel the slope, take a small step opposite the gradient. Axes are neural and live-search logits; the ball is the current mix.
Self-determined mix
How much each layer may speak
Gradient descent puts weight on layers that agree and are instrumented. A blind thank-you pixel is reliability ~0.16 — the slope pushes that weight toward zero so Ads, SEO, and Analytics cannot disagree with the file.

One file, one model
