The adjustment is made immediately and rides along with those shares.
"If a wash loss sale is triggered by another sale,"
Can't happen. only a BUY within +/- thirty days can trigger a wash sale. those bought shares are the shares adjusted.
If you bought N which is fewer than M that you sold then only N sold shares have their loss disallowed.,
Another purchase 200 days later is not involved.
