internal/ui reimplements the awg-ui backend with the same HTTP surface; the React frontend is unchanged and served from awg-ui/dist. - web.go: Express-like router (express.json semantics, mounts, :params, HTML 400/404/413 pages, SPA fallback) - server.go: JWT login with rate limit, API keys and their server sets, awg-ctrl client and proxy, /api/v1/users, delete hooks - nodes.go: WSS hub for agents (pin, challenge-response, join strings), RPC with timeouts, health, /ui/nodes - sub.go, audit.go, sub_admin.go: sen:// master keys and devices, per-server reconcile with tombstones and /api/peers/sync, signed /sub/v1 listener, audit with two-pass confirmation and cleaning, panel and /api/v1/masterkeys routers - metrics.go, monitor.go: /metrics exposition with tokens, /ui/monitor - sen.go: link codec and protocol signatures, tested byte for byte against fixtures produced by awg-ui/sen.ts (tools/golden/sen.ts) Differential bench (tools/diffbench/local-ui.sh, scenario-ui.ts, compare-ui.mjs): 158 steps over every route group, including signed device requests and a Go agent joining as a node, plus the resulting ui.db and awg-ctrl state. TS and Go are identical after masking random values, across repeated runs and with the race detector on.
