# A temporary history and its released material

The phase windows are prescribed historical response scenarios, not a derived probability of field formation or reversal. Stars return their computed winds after delays; remaining material stays locked. Multiple generations, transport and dilution can weaken or imitate the surviving pattern. Stable ground-state masses are held fixed in the resonance diagnostic.

Baseline, early and late histories evolve their gas carbon-to-oxygen ratio and gas mass. A rapid-mixing comparison shows how transport changes the contrast.

## Standard

Mass-conserving, two-reservoir enrichment driven by actual MESA wind-release kernels. No terminal explosion yield is assigned.

First: Elapsed time 0.00 Myr. The earlier-phase window is over by the final frame; current reaction parameters agree. Delayed wind release and ordinary dilution continue.

Last: Elapsed time 90.00 Myr. The earlier-phase window is over by the final frame; current reaction parameters agree. Delayed wind release and ordinary dilution continue.
