Shrinking the high-frequency residue (band closure) #
The proved reduction leaves the signed central-decay budget open for
all central frequencies ‖freq(α+β)‖ > ε⁻¹. This file closes the
routed band ε⁻¹ < ‖freq(α+β)‖ ≤ truncOrder ε · ε⁻¹ unconditionally
from the interior inserted-majorant estimate: at the maximal admissible
increment count nInc = truncOrder ε the routed argument
‖freq‖/nInc is still below the covariance frequency ε⁻¹, so the
routed decay unit is worth ε⁸/16 and the ε⁻⁸ endpoint sacrifice
closes the budget inequality exactly as in the low regime.
Consequently the remaining high-frequency residue is only the very
high regime ‖freq(α+β)‖ > truncOrder ε · ε⁻¹, where the covariance
bracket satisfies ε‖freq‖ > ⌊|log ε|⌋ and the paper's rapid symbol
decay first has genuine room.
Band closure of the signed budget. For central frequencies up
to truncOrder ε · ε⁻¹ the routed decay unit at the maximal
increment count nInc = truncOrder ε is still worth ε⁸/16, so the
mode-decay aggregation and the ε⁻⁸ endpoint sacrifice close the
budget inequality on the whole band.
The very-high-frequency residue. Only central frequencies
above truncOrder ε · ε⁻¹ remain: there the covariance-scale bracket
satisfies ε‖freq(α+β)‖ > ⌊|log ε|⌋, the regime where the rapid decay
of the covariance symbol first has genuine room. The band
ε⁻¹ < ‖freq(α+β)‖ ≤ truncOrder ε · ε⁻¹ is discharged by
signedCentralDecay_ineq_of_interiorCore_bandFrequency, so this Prop
is strictly smaller than R324HighCentralFrequencySignedBound.

Instances For
The very-high residue is monotone in the amplitude.
Shrinking the high-frequency residue. The interior
inserted-majorant estimate and its aggregated amplitude close the band
ε⁻¹ < ‖freq(α+β)‖ ≤ truncOrder ε · ε⁻¹ with nInc = truncOrder ε,
so the full high-frequency signed bound follows from the very-high
residue alone.
The reduced final assembly at the very-high residue. The paper
bound (3.24) in its frozen paperDeterministicMomentRHS shape at an
ε-uniform outer constant follows from the interior inserted-majorant
estimate together with only the very-high-frequency residue of the
signed central-decay budget: central frequencies up to
truncOrder ε · ε⁻¹ are closed unconditionally here.
The sharpened complete reduced form of the deterministic moment estimate.
The paper bound (3.24) at ε-uniform constants follows from exactly
two residual scalar statements: the ε-uniform interior-core
logarithmic budget, and the signed bound at central frequencies above
truncOrder ε · ε⁻¹ only. This strictly improves the proved
reduction, whose second residue began at ε⁻¹.
