initial: svc-proxy — UDP valve for Simple Voice Chat
Standalone Go service that routes SVC client traffic to per-server
backend voice endpoints, configured via pg LISTEN/NOTIFY (same channel
mc-router subscribes to). Each pg `servers` row with both
`voice_address` and `voice_proxy_port` set spawns a Valve: a public
UDP listener that maintains per-client ephemeral bridges to the
backend's SVC port.
Pieces:
cmd/svc-proxy/main.go entry; wires config, log fan-out,
bridge.Manager, pgsync, httpsrv
internal/config/ DATABASE_URL + BIND_HOST +
BRIDGE_IDLE_TTL (default 1m) +
HTTP_ADDR (default :8081)
internal/pgsync/ LISTEN automc_routes_changed; diff
desired/actual routes; emit Apply()
internal/bridge/ Valve per public port; per-client
bridge with atomic up/down byte counters;
idle eviction every 15s against TTL
internal/httpsrv/ operator UI — embedded single-page HTML
with active-connections table polled
every 1s + SSE log stream
(last 500 lines backlog on connect)
Reverse-proxied behind server-manager at /infra/svc-proxy/* — bind
internal-only addresses for production; auth is the dashboard's
Basic gate.
