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

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.
