Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Access Control: Missing checkMember modifier on transfer and mint allowed unauthorized token operations; fix added modifier but sibling paths may still lack it.
Authorization Bypass: ERC1404 restriction logic moved out of hook to ensure enforcement; risk of other hooks or paths bypassing restrictions.
Access Control Bypass: Incorrect bit shift in getMSBits allowed frozen tokens to transfer; similar bit operations in other functions may have analogous issues.
