Recurring patterns

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

Auth Bypass: A critical logical inversion in the proxy routing logic allowed normal users' transactions to incorrectly route to the admin logic implementation instead of the fallback path. This could cause complete administrative control takeover.

Sandbox Escape: The lack of rigid dynamic call boundaries in the WebAssembly runtime allowed guest programs to access unconstrained host functions via cross-module calls, compromising the isolation model of the system.

Denial of Service: Deadlocks occurred in the execution engine when context cancellations did not stop message resequencing, or when panics prevented releasing the block creation mutex lock, freezing block production.
