  While substantial progress has been made in studying the pre-reconstruction
galaxy bispectrum, investigations of the post-reconstruction bispectrum are
still in nascent stages. In this paper, we present a bispectrum model that
incorporates one-loop corrections in the Standard Perturbation Theory (SPT),
while simultaneously addressing infrared (IR) effects in the
post-reconstruction density fluctuations in a non-perturbative approach. This
model accurately captures the nonlinear behavior of the Baryon Acoustic
Oscillation (BAO) signal within the post-reconstruction bispectrum framework.
Furthermore, the incorporation of the one-loop correction extends its
applicability to smaller scales. Given that the approach to addressing IR
effects remains invariant before and after the reconstruction process, the
resulting IR-resummed bispectrum model exhibits uniformity across both
scenarios. Throughout this analysis, we achieve a comprehensive and unified
description of the bispectrum that seamlessly spans the pre- and
post-reconstruction phases. An explanatory video is available at
