Message Notification Router

An AI-powered, personalized notification router for WhatsApp-style messaging. A single Gemini call per message makes the final notify/digest/mute judgment, informed by a deterministic feature layer that joins user, group, business, and historical-message data to compute recipient engagement/dismissal history, group trust and quiet hours, and a scored shortlist of that user's own relevant past messages. Images and voice notes are described/transcribed by Gemini before classification, and evidence message IDs are restricted at the schema level to the real shortlisted candidates, so hallucinated evidence is impossible. A system prompt treats message content as untrusted data to defeat prompt-injection attempts embedded in the messages themselves.
