A native macOS network monitor that renders live traffic as a top-down neon city: your Mac is downtown, remote orgs are glowing districts, and traffic is cars of light driving the roads. Architecture: - NetworkCityCore: swappable data layer behind a ConnectionSource protocol (nettop-backed today), plus pure/tested logic — traffic diffing, org classification (reverse-DNS + CIDR), traffic classes, hub-and-spoke expansion policy, label anti-overlap, and latency→distance layout. - NetworkCityApp: SwiftUI + SpriteKit city — auto-expanding districts, protocol-coloured cars, click-to-inspect panel, and latency-as-distance (districts glide to their measured RTT). - nettop-probe: CLI proof of the data layer. 44 tests passing.
