docs(simulation): accept S1C live worker

@@ -126,6 +126,16 @@ The current `MissionCore-Sim` WSL2 distribution on the D drive is this
 topology's first qualified worker. Its native Gazebo window is local diagnostics;
 the product view remains browser-native.
 
+The first implemented registration slice is S1C commit `b7ccca3`. Mission Core
+and the worker share only a private mode-`0600` Unix socket in the WSL mount
+namespace. PX4, Gazebo and Micro XRCE-DDS stay inside the worker's
+loopback-only network namespace and run as the unprivileged `missioncore`
+identity. Run artifacts and provider logs remain under the admitted D-only
+roots. The React client calls same-origin Mission Core endpoints and never
+receives the socket path or a provider endpoint. Remote/routed worker
+registration is intentionally not inferred from this local laboratory
+transport; it requires an authenticated contract of its own.
