Claims (3)

claim

Peak anchoring Sbmax and normalized area AUSN correlate with per-item success and internal shot midpoints θ50, providing a geometry-to-behavior bridge.
supports
Main interpretation of E3.
Layer-wise geometry summaries (Sbmax, AUSN) predict internal few-shot thresholds θ50
supports
Claim that geometry-to-behavior correlates exist
Math and code tasks require deeper processing to bind complex patterns, as evidenced by strongest mid-layer anchoring at layers 8-12
supports
Task-specific interpretation of E3 anchoring pattern differences
