+## S1B target lifecycle
+
+Exact generation `6cb1495` is the first product-owned real-provider acceptance.
+`SimulationApplicationService` persisted the lifecycle while the worker adapter
+created a fresh loopback-only namespace and `PosixProcessSupervisor` owned two
+dedicated PGIDs: Micro XRCE-DDS Agent and the combined PX4/Gazebo stock
+Ackermann launch. The run became `running` only after the exact world/model,
+PX4 startup and DDS-writer markers existed. No arm, setpoint or other PX4 shell
+command was sent. Stop produced `completed`, eight events, zero commands and no
+process residue.
+
+This decision accepts UI-0 implementation against persisted run history. It
+does not widen command authority or accept pause/step/reset, canonical
+telemetry, frame conversion, watchdog/failsafe behavior, navigation or physical
+control.
