Recurring patterns

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

Auth Bypass: Untrusted pull request comments could trigger administrative or arbitrary command execution inside the CI pipeline if commenter write permissions were not rigorously checked and isolated.

Code Injection: Evaluating untrusted runner output by sourcing result files as shell scripts allowed arbitrary command injection inside workflow steps.

Memory Safety: Generating tailcall IL instructions while local variables were pinned could bypass garbage collection boundaries, leading to memory corruption.
