Unsigned builds — your OS may warn before opening. Onboarding, TPM-backed identity, and the chat view are functional; there is no production carrier integration for SMS/RCS/mail yet, and storage is in-memory only (no SQLCipher persistence) until a known build blocker on Windows is resolved.

Status

Actively developed, not production-ready. The Rust core (crypto, sessions, routing) is tested and stable. The Go backend's discovery and relay services are real; the SMS/RCS/mail gateway is a stub pending real carrier integrations. Source is private for now.
