  "abstract": "We identify a strange-quark-number-dependent hierarchy in the response to explicit partonic dynamics by comparing PHSD5.2 with its hadron--string limit in baryon-rich Au+Au collisions at $\\snn=3.0$--$7.2$~GeV. Crossing the local conversion threshold alone does not ensure a visible final-state signal: abundant-hadron flow changes little at 3--4.5~GeV, whereas the fractional yield response becomes ordered at 6.2--7.2~GeV, reaching $S_{|s|=1}\\simeq0.2$--$0.3$, $S_{|s|=2}\\simeq0.65$, and $S_{|s|=3}\\simeq0.93$ at 7.2~GeV. The hierarchy is consistent with an enlarged recombination phase space for strange constituents released from different pre-hadronic sources, but does not by itself establish an increase in the total $s+\\bar s$ abundance or stronger strange-quark clustering. Since $S_X$ is a model-defined response rather than a direct observable, matched excitation functions of $Ξ^-/Λ$ and $Ω^-/Λ$, together with high-$m_T$ proton elliptic flow, provide experimentally accessible discriminants between the predicted PHSD and HSD dynamics.",
