The point is blast-radius coupling: memory written in a low-privilege chat context is later executed in a high-privilege browser-control context, so a poisoning that looked harmless becomes browser takeover. Complements LayerX's CSRF memory-write finding four days later (2025-10-openai-atlas-tainted-memories) - different write primitive, same persistence problem.",
