Global Federated Stable Interoperability Protocol v1.0

✦ About

ANTARES is GFSIP v1.0 — the Global Federated Stable Interoperability Protocol. It provides encrypted, multi-channel, recoverable cross-domain communication for services, AI agents, devices, and organizations with no central authority required. Built on QUIC as the mandatory transport layer and deterministic CBOR serialization, it includes built-in session recovery, idempotent deduplication, and causal auditing as the stable foundation for decentralized networks.

✦ Key Capabilities

#	Capability	Description
1	Encrypted Sessions	Mutual-TLS or token-based authenticated sessions over QUIC
2	Multi-Channel	Independent logical channels within a single session
3	Session Recovery	Resume sessions across network switches without re-authentication
4	Idempotent Side Effects	Limited-window deduplication via idempotency keys
5	Causal Audit (opt-in)	Signed event records with declared causal predecessors
6	Cross-Domain Federation	Multi-trust-anchor routing with signed domain descriptors
7	Fault Isolation	Single-domain failure does not block intra-domain traffic

✦ On the Wire

GFSIP uses a 44-byte fixed header over QUIC with ALPN gfsip/1. Extension headers use deterministic CBOR (big-endian, shortest encoding). 18 standard message types (0x01–0x16) cover the full lifecycle: handshake, channel management, data transfer, session recovery, audit events, and federation routing.

✦ Protocol Profiles

Core/1 (Mandatory) — QUIC transport, version negotiation, mutual auth, session & channel management, session recovery, structured errors, and graceful shutdown.

Audit/1 (Optional) — Signed causal event recording with declared predecessors, actor identity, rule version, and state-before/after hashes. Self-loop and known-cycle rejection.

Federation/1 (Optional) — Cross-domain routing via signed DomainDescriptor objects, multi-trust-anchor configuration, and descriptor expiry/revocation with fault isolation.

✦ Quick Start

git clone git@github.com:NOHN-AI/ANTARES.git
cd ANTARES/reference-impl
pip install -r requirements.txt
python demo.py          # end-to-end demo: handshake → channel → data → dedupe → recovery
python conformance.py   # 9 minimum conformance vectors — all passing

✦ Use Cases

• AI Agent Networks — Multi-agent task coordination with auditable trails across organizational boundaries
• Enterprise Integration — Cross-organization workflow orchestration without a central authority
• IoT / Edge — Device-to-cloud session recovery across network changes
• Finance / Compliance — Signed causal audit trails for regulatory reporting
• Healthcare — Federated data exchange with domain-level policy enforcement
• Robotics — Reliable command channels with idempotent safety operations
