    "body_text": "The strong Mpemba effect normally requires designing an initial state that suppresses a system's slowest mode, but disorder makes that mode sample-specific. The authors derive a fixed preparation from the clean chain and show that it can begin farther from stationarity yet overtake a reference in typical dephased disordered XX chains. An exact inverse-generator identity connects residual overlap to the resistance profile, revealing separate conditions for diffusion and for the expected square-root decay of overlap. The work supplies preparation circuits and a density readout; its evidence is theoretical and finite-size computational, not an experimental speedup.",
