## ⚡ 60-Second Summary
+
+
- **What is wired:** Compose screens attempt glasses capture, Supabase Edge Function invocation, Android speech, face enrollment/matching, chat, notes, and in-memory story UI. At this revision `SupabaseAiService` discards every successful model reply and returns fixed success text; those assistance flows are not verified as useful end-to-end.
+
- **How:** Native Kotlin app (`src/frontend/`) — single activity, Jetpack Compose, service-singleton architecture. Meta **MWDAT 0.7.0** capture/registration code is present, but gesture callbacks and hardware behavior are untested. Active AI calls target Supabase `chat-vision`; the AWS `/api/chat` client/prototype is unreferenced by production app code.
+
- **Privacy status:** cloud `face_embeddings` are the active enrollment/matching path. Local encrypted 90-day storage is unreferenced; schema/RLS/consent claims are not proven. See [[08-Data-Model-Supabase]].
+
- **Mascot:** Netra the Owl 🦉 (+ Cosmo, Sage, Ripple companions). See [[05-Avatars-Companions]].
