PLN, from the stage: "moving from track X to Y, i had to press states like
^42 twice to 'apply their state'? was weird". ^42 is row E, column 2 — a
driver-owned latch.

carry_values deliberately emits no CC for buttons, because a 0 into a midiOn
gate is someCyclesBy 0 and the stream stops playing. It also cleared the
driver's latch, on the reasoning that LEDs should stop lying across a change.
Those two halves contradict: nothing is sent, so Tidal's bus still holds 127,
while the driver now believes 0. The next press computes 'not False' = ON and
re-sends 127 into a bus already at 127 — inaudible — and the press after it
closes the gate he was trying to open.

Not a hypothesis. The lcxl3-driver journal logged 37 of these across 14 of
the 2026-09-24 set's 15 track changes, and the service runs without
--no-latch, with Midi Through cut, so the doubled-CC path is not involved.

The fix is a deletion: the latch IS what Tidal sees, so it survives exactly
as the CC value does. Row F stays momentary — its release travels the generic
path and really does send 0. A carried latch now paints lit under the new
track's label, which is true, and doubles as the ghost-gate indicator this
surface never had.

The test's own assertions are checked against the pre-fix code: both fail
there.
