We introduce the hadron-anchored energy correlator (HAEC), a jet-restricted realization of the fragmentation energy correlator and the semi-inclusive energy correlator frameworks, and apply it to heavy-flavor-tagged jets in hadron collisions. Using Pythia 8 simulations of D0 - and Λ+ c -tagged jets, we find a pronounced, localized suppression of energy flow around the Λ+ c relative to the D0 , followed by a sharp transition scaling as θ0 ∝ 1/pjet T with little tune dependence. The conventional jet-axis radial profile shows qualitatively different color-reconnection dependence, suggesting reduced sensitivity of HAEC to jet-axis effects. A beauty-sector study can distinguish a heavy-quark-mass origin from a local fragmentation-vertex origin.
