Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Cryptography: The initialization vector (IV) for Common Encryption (CENC) was previously configured with a static, zero-filled value when dummy IVs were disabled, leading to predictable keystreams and potential plaintext recovery. Future modifications to track-encryption implementations must ensure secure random initialization is consistently utilized.
