A respectable bake. You'd come back tomorrow for another.
Summary
An analysis of Meta's Stella companion app for smart glasses reveals a fully built but dormant on-device facial recognition pipeline. The app contains three face models, a local database schema, a cosine-similarity vector index, a biometric write path to disk, notification surfaces, and a "Connections" widget — all present in the code but not yet activated for users. The article explores the technical details of this discovery and the implications for privacy and biometric data handling.

· 3 pulledI found the entire computational and storage stack for on-device facial recognition: three face models, a local database schema, a cosine-similarity vector index dimensioned to match the models, a write path that stages biometric records to disk, a fully wired notification surface, and a user-facing 'Connections' widget.
I want to be precise about what that does and does not mean, because the gap between the two is important.
