Componentwise q = 1 circ control at a larger exponent from the full
vector q = 2 negative seminorm at a smaller exponent, with the geometric
loss from the exponent gap.
Componentwise q = 1 circ control at a larger exponent from a scaled
negative-vector partial bound at a smaller exponent.
A scalar L² function is locally admissible as a p = 2 Besov dual test
at every descendant scale.
Sharp fluctuation estimate without the redundant average tail on the negative Besov side. This is the bridge form of the sharp vectorized duality bound used in the note-facing Caccioppoli proof.
Sharp fluctuation estimate with the positive-side input stated directly as
componentwise dual-test bounds. This avoids forcing callers through the finite
q = 2 positive Besov package when they already have an infinite-depth
q = ∞ cutoff-product estimate.
Sharp q = 2 fluctuation estimate without the redundant average tail on
the negative Besov side.
