Praveen Perera links to Spinroot's Rule 8, a coding standard that forbids using mixed operations with the same operator and that emphasizes explicit parentheses. Held as a dated technical commentary implying the vulnerability may relate to coding-style rules. The implication is the poster's own and is not independently verified here.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
