gig-up picks the painter once at launch; a board that enumerates later never
got one and no fader reached Ardour. The unit stays manual (it crash-loops and
Conflicts= the v2 painter on a v2-only box), so the loop that already knows
which generation is plugged in re-runs the chooser: start, not restart, raw
kernel client only, never the v2 painter, bounded retries with a cooldown.
