The C2 system's entry/exit portal. Receives raw military traffic via UDP unicast and multicast, validates, normalises, and distributes it to downstream consumers via broadcast bus and TCP push. Exposes a TCP ingest pipeline that accepts XML injections from internal components and forwards them UDP to whitelisted partners.

• 7+ independent modular crates
• YAML-configurable pipelines
• Backpressure-aware (MPSC bounded)
• 44 DIS v7 PDU types
• Partner whitelist for UDP inject
• Session replay via Message Recorder

The system's memory. Connects to Ermes' TCP push, converts JDSS messages to DIS v7 PDUs, and persists them in a SQLite database with session management and an interactive SQL REPL. A second binary atop the DB exposes a REST API (Axum) providing real-time tactical state to Arianna.

• 3 crates: jdss-dis (lib) · recorder · api
• WGS-84 ↔ ECEF (NIMA TR8350.2, no lib)
• Session resume with entity mapping warm-load
• Trait-based EntityResolver (swappable impl)
• Interactive SQL REPL + --query mode
• API serves Arianna directly for reads

The tactical brain. Computes optimal paths for land, air, maritime, and submarine assets over real geospatial terrain, accounting for elevation, threats, weather, sensor coverage, and restricted zones. Tactical state is read exclusively from Atlante's REST API: no state duplication.

• 4-layer cost model (slope · terrain · threat · obstacles)
• LOS-aware threat map (Bresenham)
• Grid assembly 2.8× speedup (Rayon)
• Copernicus GLO-30 DEM · ESA WorldCover
• OSM buildings/roads (Geofabrik)
• Target latency < 1s per request

The node's tactical voice. Embodies a single field unit (e.g. ROMEO1) and speaks JDSS IEM (AEP-76 / ADatP-36A) with network partners. Connects to Ermes on two channels, orchestrates the REPATH cycle end-to-end with Atlante and Arianna, and manages state (HeartBeat, Presence, Sync).

• Fixed GatewayID · SessionID renewed on each start
• Configurable tactical identity (OID + callsign)
• Auto-reconnect to Ermes channels with backoff
• Handlers for Presence · Identification · Overlay · GenInfo · Sync
• REPATH cycle: partner → latacc → arianna → partner
• End-to-end C2 system glue layer
