Recurring patterns

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

Cryptographic Error: The Schnorr signature verification routine incorrectly used the private key variable instead of the signature scalar component 's' in its elliptic curve multiplication, leading to potential verification bypasses.
Cryptographic Error: The Schnorr signature generation logic ignored the caller-specified custom generator point, falling back to the standard base point multiplier 'sbmul', which can lead to invalid signatures when custom parameters are expected.
Cryptographic Error: Signature verification points were improperly serialized or truncated during hashing (only using the first coordinate), degrading the cryptographic strength or correctness of AOS Ring signatures.
