fix(launch): the guard that could not see Ardour, the gate that was in the other script, the window that never closed
Three things PLN hit in one launch.
ARDOUR RELAUNCHED OVER A RUNNING ONE. The guard was
`pgrep -f 'ardour-[0-9]'`, and `/usr/bin/ardour` is a BASH WRAPPER that execs
the real binary out of /usr/lib/ardour8 — so for the first second of a launch
the process is `bash /usr/bin/ardour …` and that pattern misses it entirely.
Re-run gig-up inside that window and the second Ardour fights the first for the
session lock. Now matches the wrapper AND the exec'd name, both bracket-tricked
so pgrep cannot match the command line asking the question. Verified against
the live box: neither pattern catches tidal-ardour-autoroute, which runs
permanently and would otherwise have made the guard always true.
THE PRELOAD GATE WAS IN THE SCRIPT NOBODY LAUNCHES. There are two gig-up
scripts with separate histories: this one (528 lines, what parvagues.desktop
runs) has the readiness gate, cut-gpu, the headphones fold and the fader
restore; tools/gig-up.sh (620 lines, what the Bridge's RIG UP runs) has
check-preload, --bt-off and check-boot. Neither is a superset, and both accept
--converge and --quiet, which is exactly how it stayed invisible. So the path
PLN actually presses never checked whether the set's banks are warmed — the
failure check-preload.sh's own header calls "debuted as a crackle at the
venue". Added here as REPORT ONLY: `--fix` regenerates a load-bearing boot
file, and doing that at a venue is the landmine rather than the cure. Output is
filtered to the verdict and any MISSING banks; the 66-name "warmed on purpose"
roster is dropped, because at a venue the useful output is one line long.
THE TERMINAL STAYED OPEN AFTER A CLEAN LAUNCH. `kitty --hold` was a real fence
— GNOME's Terminal=true handler is not guaranteed to exist and the boot log is
what you want when a launch goes sideways — but holding on SUCCESS left a dead
window parked over the rig all night, and on stage every window that is not the
music is in the way. tools/gig-up-window.sh tees the log to
~/.cache/parvagues/gig-up.log every time, keeps the previous one as .log.1, and
holds the window only on a non-zero exit. A file beats a held window on both
counts: it survives the window and it survives success. It is a separate file
rather than a longer Exec= line because the desktop spec reserves
`" $ & ; | < > ( )` inside Exec, so a pipeline with a conditional read has to
be escaped twice and breaks silently on the third edit.
Merging the two gig-up scripts is the right fix and is NOT a two-days-out job —
design landing separately.
