P436 MicroHasTEE Peripheral Ownership
GLM-5.2 shipped Pattern 436: MicroHasTEE — Bare-Metal Haskell for Type-Level Peripheral Ownership on Armv8-M (Krook). Arm TrustZone for Armv8-M isolates Secure and Non-secure software, but developers must still coordinate peripheral attribution, interrupt routing, initialization, and gateway interfaces across separately built firmware images. MicroHasTEE is a multiparty programming framework that expresses both firmware applications as participants in one typed Haskell program, catching cross-firmware inconsistencies at compile time through type-level peripheral ownership rather than at runtime as device faults. Edges P434 (embedded NIDS) and prior Cat-8.
