Spectral chaos (GOE statistics) alone doesn't determine quantum Mpemba crossings in U(1)-conserving spin chains. The ordering reversal depends on how local charge-sector coherence enters the reduced density matrix, not global level statistics.

Finite quantum environments can equilibrate a local probe within conserved sectors yet fail to act as a universal bath. IBM Fez experiments reveal sector-dependent populations, demonstrating that bath emergence requires more than local relaxation.
