+# Airship multiplayer server
+
+Go transport/authentication service for the Phaser airship game.
+
+Current slice:
+
+- verifies Keycloak access tokens
+- persists authenticated player profiles to PostgreSQL
+- issues one-time 30-second WebSocket tickets
+- maintains one live connection per Keycloak subject
+- validates and broadcasts player transform/hull snapshots at 10 Hz
+- exposes `/health`, `/api/me`, `/api/ws-ticket`, and `/ws`
+
+This is intentionally a transport/presence milestone. Player combat, pirates, projectiles, trading and economy still run in the Phaser client and are the next systems to move server-side.
