Earned during the phase-2 button remap (5910aacc). The migrator left an over-budget
control where it was, which LOOKS conservative and is the opposite: once ^42 became
d2's button, d1's surviving reference to ^42 meant one press fired both orbits.
perfect.tidal shipped that way until a hand-written check found it — and that check
then existed only in a terminal scrollback, which is not a gate.
WHY IT DESERVES TO BE AN ERROR, NOT A WARNING
Nothing errors. Nothing goes silent. The extra layer only appears while a specific
button is held. On stage that reads as "the track is broken today" rather than as a
mapping bug, which is the exact signature of the failures this rig keeps losing
evenings to. Same family as the orphan-orbit ghost: audible, plausible, and invisible
to every static check we had.
WHAT IT DOES NOT FLAG — the cry-wolf cases, each a real line from the corpus
* gF1-3 and gMute1-3 (and gPanic) are per-FAMILY BY DESIGN — measured, not assumed:
gF1 -> d1/d2/d3/d8, gF2 -> d4, gF3 -> leads. Flagging those would fire on every
track in the set and the rule would be switched off within a day.
* one orbit referencing a button three times is ONE gesture, not three collisions
(bombe_dj's kick does exactly that) — findings are per ORBIT, as in PV004.
* COMMENTED-OUT gestures. This matters more than it looks: commenting the surplus
is precisely how #94 parks an over-budget control, so a rule that counted
comments would fail every track the migrator just fixed.
* knobs. Knob sharing is a columns question, not a button collision.
VALIDATION
OPAL setlist 0 PV008 findings — clean, as of 5910aacc
whole corpus 136 findings across 56 of 792 files
pvlint tests 38 passed (5 new: the real perfect.tidal case, plus one
negative per cry-wolf class above)
The corpus number is history, not exposure: those are old-world tracks that predate
the column grid, and per the measure-the-set-not-the-corpus lesson the number that
matters before a gig is the setlist's, which is zero. The corpus gets fixed when it
gets migrated (#64 / post-gig), and now there is a rule that will prove it.
