We implement a multi-layered control framework: 1) Data Tagging & Classification: All training data, model weights, and outputs are tagged with jurisdictional metadata at ingestion. 2) Policy Enforcement Engines: Real-time systems (e.g., Open Policy Agent) block any cross-border data movement at the API, storage, and network layers. 3) Hardware & Network Segmentation: Workloads are pinned to localized compute clusters (e.g., sovereign GPU pods) within air-gapped or logically isolated networks. 4) Provable Audit Trails: All data access and movement events are immutably logged, with cryptographic hashes, enabling third-party compliance audits.
