   | :---: | :--- | :--- |
   | 2 | Parity (Even/Odd) | The residue classes $\bar{0}$ and $\bar{1}$ exhibit perfect binary oscillation. |
   | 3 | Triadic Structures | Often used in early cryptological substitution ciphers due to its ease of visual partitioning $[2]$. |
   | 4 | Sub-Harmonic Partitioning | Exhibits a known temporal resonance anomaly when observed across periods exceeding $10^{12}$…
