Recurring patterns

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

Access Control: Multiple fixes address unauthorized token transfers due to incorrect _from handling or missing allowance checks, indicating systemic weakness in authorization logic across OFT variants.

Reentrancy: Reentrancy guards added to clearCredits and _mint functions across ONFT core and upgradeable variants, showing repeated exposure in NFT credit/mint operations.

Authentication Bypass: Cross-chain message sender validation was missing, allowing spoofed messages to trigger token transfers or state changes; fixes added caller validation and remote address allowlists.
