Then, after the step loop, twelve things the mock cannot do at all: a
force-stop and the paused restore that follows it (waited out past
twenty-five seconds, which is well past the ten-second FGS-kill window), the
position restored, playback resumed, the system media session and its
ownership, media keys, exactly one card in the shade and exactly one session
in the system's list — the two checks that prove the media3 migration landed
rather than doubled — the two intent filters Android Auto knocks on, the
legacy browse one and media3's own, both resolving to `MediaService`
(`auto-browse`, `auto-library`: the catcher for a plugin module that
compiled and never reached the APK, which is how this project once got a
start-up `ClassNotFoundException`), ten seconds in the background with the
position still advancing, SoulStream's own mixer underruns, and the queue
window that rides along with every card update and that the lock-screen card
is now built out of. Two more lines print and never fail: whether the service
is foreground, whether our audio focus is in the system's stack and whether
the becoming-noisy receiver is registered; and the Auto declaration as
`tools/auto-prober/` last read it, because `pm dump` prints no application
meta-data and nothing else on the phone can be asked. What none of it touches
is in "What the walk proves about the card, and what it does not", above.
