WhatsApp adds an incognito mode in Meta AI chats

WhatsApp added an incognito mode for Meta AI chats; Meta says these conversations are not saved, and messages disappear by default once the chat is closed.

Why it matters: HKR-H/K/R all pass: the privacy hook is clear, the retention mechanism is concrete, and WhatsApp gives it scale. Still, this is a single product feature, not a model or platform shift, so it sits at the featured threshold.
