Recall Probability Curve — Asymmetric U-Shape (model-specific)

Based on Liu et al. 2023 "Lost in the Middle"

■ Primacy (stronger than recency) ■ Middle (danger zone — skewed past center) ■ Recency (high recall, weaker than primacy) Dashed = symmetric reference

Memory Architecture Map — Token Blocks

Hover / tap block → decoded token preview + recall %

Ready — paste text or upload a file to visualize token memory architecture

Zone 1 · Primacy (highest recall — slightly brighter)

Zone 2 · Lost in Middle (danger — dip skews past center)

Zone 3 · Recency (high recall — slightly weaker than Primacy)

Zone 4 · Overflow (truncated — model never reads)
