control-events.log records that a [mpris] PlayPause arrived but not who sent
it — PyQt6 has no QDBusContext, so the adaptor can't see the caller. This tails
dbus-monitor, filters MPRIS method calls, and resolves each sender's unique bus
name to a pid and cmdline, which is the other half of the picture.
It has already earned its place: two weeks of capture show every
playback-affecting call into LinTunes coming from gsd-media-keys during waking
hours, and not one between midnight and 7am — so the phantom overnight audio
was not a stray Play, which is consistent with it being the paused-but-live
PipeWire stream fixed in v0.6.1. Read-only; touches no library or music file.
