check-mix reports OK, all 12 orbits reach master. Third recurrence of the
saved--inf bug, closed by PLN's hands.

Two things fell out of verifying it. check-mix resolves the saved session with
Ardour CLOSED — it reads the file, not the process, so the fader check can run
in a pre-gig script before anything is launched. And the diff is bigger than the
fix: orbits 02-06 were in a coherent -8 to -10 dB trim set and are now all near
unity, so nine faders moved where four were broken. Master is still -0.2 so
nothing clips, but the balance between orbits shifted ~9 dB on five of them.

Recorded as a QUESTION, not a finding. The LCXL3's faders are absolute-position
controls and touching one snaps the DAW value to the pot — which also means the
board's 'v3 retires pot-pickup' claim covers the endless ENCODERS only; the
eight faders are still absolute and that whole class survives the upgrade. But
PLN may simply have dragged them on purpose, and a cause nobody asked about is
not a cause.
