The call’s shape crossed the encryption at r = 0.8–0.9, a wrong-window null stayed dark, and the whole thing was legible without reading one byte of content. Then the honest half: a background stream drowned the call until it got loud, the downlink data frames stayed as unreadable as ever, and a clever one-way ICMP trick failed a null control cleanly.
