Recurring patterns

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

Authorization Bypass: Multiple high/critical fixes address missing validation of message recipients, amounts, or message IDs, allowing unauthorized fund transfers or withdrawals.

Denial of Service: Recursion depth caps, gas limits, and resource size limits were added to prevent unbounded loops and excessive consumption that could stall message processing.

Insufficient Payment Validation: Insufficient msg.value checks allowed underpayment of fees or forwarding excess ETH to untrusted routes, risking fund loss.
