# -*- coding: utf-8 -*- """ TEITAN AR-88 — HYPER-V DIRECT HOST CONTROLLER Controls isolated VM execution of TEITAN internal functional contracts via PowerShell Direct (HVSocket) without network, clipboard, or shared folders. STRICT CONSTRAINTS: 1. Reuses VM 'TEITAN-AR88-LAB' exclusively. 2. Audits host Hyper-V permissions and VM existence before any operation. 3. Audits physical OS isolation barriers and result provenance (FAIL_CLOSED). 4. No network adapters or host-shared drives allowed on the VM during evaluation. 5. Ingests authentic evaluation results into InternalRepairCoordinator without bypasses. 6. Invokes autonomous reasoning without pre-supplied patch code.
