A Governance Layer for Agent‑Native Windows RTX PCs (Spark Governance SDK)

Microsoft and NVIDIA's new Spark PCs, featuring Grace CPU and Blackwell GPU, enable local frontier-model execution. The Spark Governance SDK introduces a governance layer for agent-native Windows RTX Spark PCs, including IPS scheduling, retrieval-boundary enforcement, and regulator-facing compliance APIs to address EU AI Act and NIST AI RMF requirements.

Spark Governance SDK Governance‑Layer Architecture for Agent‑Native Windows RTX Spark PCs Version 0.1 — Conceptual Architecture Overview The Spark Governance SDK defines a governance‑layer architecture for agent‑native Windows RTX Spark PCs, integrating governance primitives with the new execution substrate introduced by Microsoft and NVIDIA. Spark PCs provide: Grace CPU + Blackwell GPU unified memory up to 128GB Windows Workload Profile Scheduling WPS NVIDIA OpenShell secure agent runtime Windows agent security primitives Local frontier‑model execution 120B parameters, 1M tokens This SDK introduces the missing governance plane: IPS Scheduling Retrieval-Boundary Enforcement Multi-Agent Orchestration Attestation & Provenance GPU-backed Settlement & Verification Regulator-Facing Compliance APIs This repository provides the architecture, diagrams, and integration notes for a Spark‑native governance layer. graph TD subgraph Agent Layer APPLICATION / AGENT LAYER A Local Agents B Multi-Agent Graphs C High-Context Workflows end subgraph Gov Plane SPARK GOVERNANCE PLANE G1 IPS Scheduler G2 Retrieval-Boundary Engine G3 Multi-Agent Orchestrator G4 Attestation & Provenance G5 Settlement & Verification G6 Regulator API end subgraph Spark Substrate SPARK EXECUTION SUBSTRATE S1 Windows WPS Scheduler S2 NVIDIA OpenShell Runtime S3 Grace CPU + Blackwell GPU S4 CUDA/TensorRT/RTX Pipelines end Agent Layer -- Gov Plane Gov Plane -- Spark Substrate style Gov Plane fill: f9f,stroke: 333,stroke-width:2px style Spark Substrate fill: e1f5fe,stroke: 01579b,stroke-width:2px Motivation Agent-native PCs require governance primitives that operate: locally deterministically with hardware-backed attestation with secure retrieval boundaries with multi-agent arbitration with regulator-visible outputs Spark PCs finally expose the OS and hardware primitives needed to implement a true governance plane. This SDK proposes how such a plane can be structured. Core Components IPS Scheduler Maps Importance Prediction Score → Windows WPS scheduling. Risk-weighted prioritization for agent workloads. Retrieval-Boundary Engine Enforces data scopes, provenance, and access rules inside NVIDIA OpenShell. Multi-Agent Orchestrator Runs agent graphs under governance constraints. Supports delegation, arbitration, and conflict resolution. Attestation & Provenance Binds agent identity, retrieval boundaries, and hardware attestation. Integrates with Windows agent security primitives. Settlement & Verification Uses CUDA/TensorRT/RTX pipelines for deterministic verification. Supports cross-modal consistency checks. Regulator API Outputs structured compliance events for: EU AI Act NIST AI RMF ISO/IEC 42001 Today Draft my GitHub README for Spark Governance SDK Below is the GitHub‑ready README for your new repository spark-governance-sdk. It is structured, professional, academically aligned, and tuned for Hacker News, Microsoft/NVIDIA partnership decks, and EU AI Act governance audiences. It reads like a real SDK landing page — concise at the top, deep underneath. I’ve embedded Guided Links naturally so you can expand any section instantly.
