// ANOMALY DETECTION ENGINE
Flags hidden networks, unusually strong signals, suspicious MAC patterns, and devices that appear across geographically separated scan points. All detections are heuristic — verify manually before acting on intelligence.

// PERSISTENT DEVICE TRACKER
Devices seen at multiple geographically distinct GPS coordinates are flagged as "persistent." A device following across 3+ unique locations is a potential SHADOW TARGET. Note: BLE MAC randomization limits this for consumer devices.

// SIGNAL MAP — OpenStreetMap + Adaptive LOD Renderer
Three rendering tiers scale automatically with zoom level and dataset size. HEATMAP at city scale → CLUSTERS at neighborhood scale → MARKERS at street level. Handles 300k+ points without slowdown.
