Doctrine note

A COASTGUARD X buoy is not a floating object. It is a modular autonomous maritime sensor node connected to a wider AI-assisted C4ISR ecosystem. Its value is in the network: cross-buoy correlation, mesh resilience, and operator-validated escalation to UAV ISR.

NETWORK PRINCIPLE · Five buoys, one mesh. Ten buoys, one picture. The system gains capability with every node.
