Observer Dynamics for Alignment Safety: A Measurement-Theoretic View of CoT Monitorability and Failure Modes

This update adds Appendix A.5 and supplementary figures to the existingAOD (AI Observer Dynamics) record. Appendix A.5 provides a minimal, non-operational toy experiment thatillustrates resonance-driven drift predicted by the AOD framework.The experiment uses only externally observable quantities and isintended for descriptive and diagnostic purposes. Added materials include:- Appendix A.5 text (toy experiment description)- Summary data and plots (mean trajectories and risk regime rates)- A state-space overview figure illustrating stable regions and drift No changes have been made to the main manuscript.
