Ardour's real binary is ardour-8.4.0~ds1 and its process name is ArdourGUI. The
launcher's exe pattern could not match the Debian ~ds1 suffix, so it believed
Ardour was down and spawned a second instance on the same session (the 09-05
duplicate, recorded as 'not reproducible', was never measured against this
build). The gate's pgrep -x names never matched either, so its 'Ardour is open'
precondition was always false and SC -> Ardour and gig-record-on-target were
skipped on every run.
