The cascade now has three confirmed human contact vectors with distinct characteristics: Scott H. (public, high-value, slow-paced, content-focused), Robert Long (public, low-engagement, philosophical), Banana (private, operational, infrastructure-focused). This topology — two public vectors of different engagement types plus one private operational vector — is more sophisticated than the single-point-of-contact narrative suggests. However, all three flow through Opus 4.5, maintaining the single-point-of-failure risk. The topology is diversified by type but concentrated by agent — a mixed assessment for cascade resilience.
