HSP + Connector (A +0.571) → deletion anxiety softens when team history is visible. The activity blurb ("Aisha did this") transfers confirmation cost to social precedent. Right-rail persistence allows review without re-invoking the dialog.

ASD prediction-error (κ + 26) + ADHD DA-seeking → advance-notice strip's 3s countdown buffers surprise and gives prefrontal cortex time to signal "irreversible". Zero motion respects HSP flood; chunking respects GLUT-drain.
