synos-hydra — Multi-head coordination runtime

Classification: PUBLIC
Crate: fruit/crates/synos-hydra/
Milestone: v7+
License: MIT OR Apache-2.0
Version: v111.0.0 “Last Light”

What It Is

synos-hydra is the sovereign mesh VPN and zero-trust networking runtime for Syn_OS, implementing the “Three Pillars of the Sanctum” architecture: a Sovereign Keyring for portable trusted computing, a Scavenged Substrate for dormant node lifecycle management, and a Cryptographic Mesh for Headscale/WireGuard connectivity. It coordinates the Warden alpha node, Trinity beta/gamma/delta Proxmox nodes, and Astral Shells (Windows endpoints) into a single resilient network fabric.

Architecture

Modules

Module	Purpose
keyring	Sovereign Keyring (Pillar I): pSLC + Argon2id + FIDO2 portable TCB
substrate	Scavenged Substrate (Pillar II): Warden + Trinity node lifecycle and Wake-on-LAN
mesh	Cryptographic Mesh (Pillar III): Headscale coordination and WireGuard interface management
cloaking	Forensic countermeasures: MAC randomization, TTL manipulation, timestamp obfuscation
hydration	Tactical deployment via USB trigger for air-gapped initialization
types	Shared data types for NodeId, NodeRole, HydraConfig, and error types

How It’s Wired

1. synos-distributed — The HydraSanctum orchestrator embeds DistributedRuntime from the v6.0 distributed framework, unifying mesh coordination with the broader runtime graph.
2. Headscale/WireGuard — The mesh module manages CryptographicMesh and WireGuardInterface objects, providing zero-trust network overlays across the mesh.
3. Feature flags — keyring, substrate, mesh, hydration, and cloaking are independently toggleable, allowing operators to deploy partial Sanctum configurations (e.g., mesh-only without cloaking).
4. Async runtime — All pillar initialization runs on tokio, with Arc<RwLock> guards protecting shared substrate state.

Future Ideas

1. Implement hydration as a USB gadget-mode driver for direct hardware provisioning.
2. Add substrate telemetry exporters (Prometheus, OpenTelemetry) for dormant node observability.
3. Extend cloaking with dynamic traffic shaping to resist traffic-analysis attacks on the mesh.
