Review follow-ups for the sonar pulses. Wake on user input only: a camera move wakes the pulses only within 1.5 s of a pointer, wheel or touch on the Cesium canvas, where its camera controller listens. Tracking, the cockpit view, an orbit or a fly-to move the camera on every frame and no longer keep the pulses running. Keys don't count: the camera controller reads none. Below the disc: with the camera under 2.5 km the pulses rest completely, with no disc, ring flash, echoes or frame requests. Echo brightness: echoes scale by the contact bracket's drawn alpha, which includes the Cyber sonar sweep, rounded to the nearest band with no floor, so an echo is never brighter than its bracket. Disc follow: the pulse disc follows the subject by a model-matrix rotation about the Earth's centre and is rebuilt only every 20 km instead of every 500 m. Tests: a cap on burst length; teardown through disable(); the echo's spread and alpha on the canvas; echoes under the Cyber sonar never brighter than their bracket; waking by pointer, wheel, touch and drag but not by keys, app camera moves or stale input; the rest below the disc; and tighter asserts. CURRENT-STATE notes that terrain above 2.5 km still cuts through the disc and ring.
