enumerateTweens dropped every tween whose targets() held no Element:
if (!targets.length) return;
That silently deleted the proxy-driver idiom — tween a plain object, apply the
motion inside onUpdate — which is real, visible animation. The consequence was
not just a missing row: computeDensity counted zero active tweens across the
tween's span, so findDeadZones reported animating time as DEAD, telling agents
to add motion to a stretch that already had it.
A target-less tween is now kept when a driver reaches it, marked
driver:"onUpdate". The driver can be the tween's own onUpdate, or the
TIMELINE's — the WebGL/uniform idiom is gsap.timeline({ onUpdate: renderFrame })
over children that tween plain uniform objects and carry no onUpdate of their
own, so walk() threads a `driven` flag beside parentOffset.
The discriminator is what keeps this from trading one false reading for
another. A bare `tl.to({}, { duration: D })` spacer produces nothing, and every
preset caption skin ends with exactly such a full-span anchor; counting those
would mask genuine dead zones. So a tween's own onUpdate is proof of work by
itself (a repaint loop need not animate a property), while an inherited driver
additionally requires the tween to change something.
There is no element to select or measure for a driver tween:
* selectorHint is null rather than a placeholder — it feeds
document.querySelector, so it must be absent, not unmatchable;
* bbox sampling is skipped; the report shows "(onUpdate driver)";
* computeFlags guards its geometry flags on bboxes.length, since [].every()
is vacuously true and would report an unmeasured tween as both degenerate
and invisible;
* describeTween says the motion is applied in JS and no geometry was measured;
* the per-element analyses (buildElementLifecycles, detectStaggers) run over
element-backed tweens only, so drivers cannot collapse into one pseudo-
element or invent a stagger. Density, dead zones and the timeline still
count them — those are per-span, which is what a driver has.
Verified end to end: a 4s composition with an element tween over 0-1s and a
proxy driver over 2-4s went from "1/1 tweens, dead zones: 1.5-4s" to "2/2
tweens" with no dead zone.
