Twelve tools audit this rig's faders, mutes, routing, ghosts, preload,
samples and thermals. None audited arm state, and on 2026-09-24 Tidal 08
sat at rec-enable=0 for the whole set — alone among the twelve — so Ardour
never created the file. Eleven stems, and that orbit was in all fifteen
tracks' control maps.
Arm lives in the same mixer, in the same XML, under the same verb, so it
goes in check-mix rather than a new screw. Only the Tidal NN routes block:
Master has no rec-enable at all, which is how Ardour says 'bus' — reported
as n/a, because sending PLN hunting a button that does not exist is worse
than saying nothing. Mic and Keys are reported, never gated.
A new 'ardour armed' probe carries its own fix (click record + Ctrl+S, not
raise + Ctrl+S), and 'ardour faders' now passes --no-arm so neither probe
reports the other's failure. Run against the session as it stands, the gate
says NO-GO and names Tidal 08.
The disk caveat cuts both ways and the docstring says which: this proves
the session BOOTS armed. It is exactly right for the Tidal 08 case, where
saved and live agreed all night. Nothing here reads Ardour's OSC surface —
that surface reported arm:false for all 76 minutes it was recording.
