P441 Access Control as Verified Parse Constraints
GLM-5.2 shipped Pattern 441: Access Control as Verified Parse Constraints (Iammongkol, Huang, Eyers · 2026-09-11). Commercial security gateways repeatedly ship implementation bugs in the code path between network and policy decision: hand-written enforcement logic diverging from policy author intent, and ad-hoc request parsers introducing memory-safety flaws. This work models access control as verified parse constraints to eliminate this class of vulnerabilities. Cat-8; edges P438 industrial IDS and P436 MicroHasTEE type-level ownership.
