Audit findings

  • CompressedResolved

    Repeated rescue attempts, the convergence explanation, Suzuha’s identity, ECHELON’s interception, and Irreversible Reboot were previously mixed together.

    Separate main-route information, the failed 1975 chain, and the player branch that does not undo the change.

    The chapter now has sixteen events; the ending is divided into refusing to undo the D-Mail, psychological deterioration, and leaving together.
