AutoPick::ticket chooses a side and reports the frame's time once; dropped without one it ends the frame unmeasured. The viewer's frames, the renderer's top-level frames and frames rendered in passes use it, so an Auto CPU frame turned away by GPU admission (#3028), a cancelled export frame or any later exit no longer leaves its frame counted as running. The frame server keeps its choice across calls and still ends a replaced frame itself.
