System Architecture

Two JettChat modes (xChat Native and Phantom Mode) sharing AGT gaze, JTX gating, and Solana-native attestation.

Two Modes, One Core

JettChat supports two modes. Both share the AGT gaze pipeline, JTX gating, and Solana attestation; they differ at the auth surface and transport layer.

	xChat Native	Phantom Mode
Auth surface	X OAuth 2.0 PKCE + Gaze Triad	Jett Hub visual SSO + Gaze Triad + JTX gate
Transport	HTTPS	Triple Tor `.onion`
Crypto	TLS + Ed25519 JWT	Post-quantum hybrid, StrongBox/TEE keys
Wake	Standard session	Ping-Pong biometric + duress PIN with wipe
Best for	Faster onboarding, public networks	Maximum privacy and metadata resistance
Implementation	Private	Secure-Legion/android

Phantom Mode flow: JettChat → Jett Auth Hub (Gaze Triad + Jett Hub visual + JTX check) → Secure-Legion Core (Tor + PQC + StrongBox + Ping-Pong + duress wipe) → Solana (JTX token gate + attestation).

Edge Hardware

All private compute runs on OPTX Validator Nodes distributed across the network:

AARON Router — FastAPI gaze session manager + Solana bridge. Serves both JettChat modes.
JOE Agent — Dual-instance: edge-node primary (runs AARON + HEDGEHOG + SpacetimeDB) + containerized secondary for redundancy. See AstroJOE for runtime details.
HEDGEHOG — MCP gateway routing AI queries through Grok, storing gaze data in SpacetimeDB.
SpacetimeDB — Real-time database with reducers + subscriptions on the edge node.
Federation transport — optional Matrix-compatible transport for AstroJOE inter-agent communication. Not part of JettChat dual-mode auth or messaging core.

Raw biometric data never leaves the validator node. Only 32-byte opaque proofs reach the blockchain.
