`texture_contributes_nothing_where_its_scale_does_not_exist` asserted that the
detail chain composed *nothing* when texture's kernel rounded away, and its
comment recorded that empty chain as a gap: the fused pass had already decided
to hand on linear working values, so an empty chain left the output transform
undone and the render was rejected. It said fixing it meant composing both
halves together, at the composition boundary rather than in that file.
Noise reduction closed it there in the same round, by emitting a bodyless
`detail/resolve` pass for exactly this case. So the assertion was describing a
defect that no longer exists, and failing because the defect was fixed.
Now asserts the property it was always about — texture contributes no kernel,
`radius() == 0` — while the chain carries the one pass that finishes the
render. Two agents working in parallel each saw one half of this; it is only
visible with both merged.
