Recurring patterns

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

Auth Bypass: Both historical fixes target the same sink (verifyPoly1271Signature) and class; the pattern of validating against the wrong address is a proven, repeatable flaw that can lead to full authorization spoofing on orders.
