SkyCustody is an edge-first SIGINT pipeline that solves the mentor's exact ask: a 149 KB CNN + autoencoder on-device turns 232 GB/hr of raw RF into ~600 B intelligence rows. Each event flows through a custody state machine, TDOA geolocation (Chan 1994, ~30 m CEP), blue-force attribution, and a streaming-DBSCAN persistence detector that flags "I can't explain this one." Every output streams live into 7 typed datasets on a real Palantir Foundry tenant via the publishRecord API, with a DDIL JSONL replay buffer so the edge node never loses data when comms drop. The full Find→Fix→Track→Target kill chain closes in one tactical dashboard with one-click COA execution.
