Initial spatial clustering of primordial black holes (PBHs) induced by local-type non-Gaussianity (LNG) can substantially modify cosmological constraints on PBH abundance. Existing formulations of initial PBH clustering are primarily restricted to either small non-Gaussianity or specific regimes, an
