# Phase 4W mechanism summary
Descriptive audit; no learning, model parameter change, or candidate selection. Six previously seen odors, one fixed seed each; not independent population generalization.

Replay holds all other recorded drive and the measured applied APL signal fixed. Removing a source class is a conditional single-cell test, not a closed-loop whole-brain intervention.
Drive fractions refer to delivered positive synaptic input, not fractions of biological causality or of net g. Inhibition and APL are separately accounted.
Ranked ancestry uses positive edges only; inhibitory influences are not claimed absent. Ranking is a heuristic; all path edges have real source events and arrival<=target-spike time.
Float64 category shadow max absolute residual versus actual float32 g: 1.76084011e-05. This does not alter the exact CPU replay or actual queue checks.
