+# The Winterhold Framework: Sovereign Architectures for Critical Autonomy
+
+**Status:** Research and Development Alpha / Institutional Deployment Candidate (2026)
+**License:** Custom IA_AUT_ECO Ethical License / AI B Act Adherent
+**Core Maintainer:** IA_AUT_ECO (Meaux, France)
+
+---
+
+## 1. Executive Summary: Engineering Trust
+
+The **Winterhold Framework** is a French Deep Tech engineering solution establishing the **sovereign software standard** for next-generation assistive robotics and critical autonomy systems.
+
+This framework addresses the systemic vulnerability of current assistive technologies by prioritizing **resilience, auditability, and data sovereignty** over feature commoditization. We ensure that physical safety and cognitive data integrity meet the requirements of national critical infrastructure.
+
+### Foundational Commitments (NIS2, PQC, AI Act)
+
+* **Zero Trust Architecture (ZTA):** A fundamental security model eliminating implicit trust, enforced at the Kernel and Edge level.
+* **Post-Quantum Cryptography (PQC):** Native embedding of PQC primitives to secure long-term data integrity against theoretical quantum threats.
+* **AI Act Compliance:** Built-in mechanism (Ysgrammor) enabling full decision-making traceability for compliance with High-Risk AI system requirements.
+
+---
+
+## 2. Architectural Design
+
+Winterhold operates on an **Open Core** methodology, providing a demonstrably verifiable core for institutional partners and certified manufacturers.
+
+### 2.1. Hearthfire: The Hardened Core OS
+
+A dedicated fork of **FreeBSD** engineered for embedded, real-time, and functional safety-critical robotics applications.
+
+* **Objective:** Minimize the attack surface and ensure deterministic performance.
+* **Implementation:** Incorporates advanced Kernel Hardening techniques, Mandatory Access Controls (MAC), and secure boot processes optimized for embedded hardware (e.g., NVIDIA Jetson platform).
+
+### 2.2. Fort Graymor: The Secure Edge Hub
+
+The certified communication and orchestration layer responsible for maintaining system integrity and external security.
+
+* **Function:** Enforces Mutual TLS (mTLS), manages PQC key rotation, and serves as the **NIS2 resilience component**, managing incident logging and reporting protocols.
+
+### 2.3. MASAQ and Skald: Sovereign Intelligence Orchestration
+
+Modules for optimized inference and cognitive process management on the Edge.
+
+* **MASAQ:** Manages resource allocation for low-latency inference on embedded systems.
+* **Skald:** The core cognitive agent utilizing Small Language Models (SLMs) and Graph Neural Networks (GNNs) for semantic translation and critical command execution.
+
+### 2.4. Ysgrammor: The Audit Engine
+
+A dedicated, immutable logging module providing verifiable proof of every AI decision executed by Skald.
+
+* **Mandate:** Fulfills the EU AI Act's requirement for transparency and accountability in High-Risk AI deployments.
+
+---
+
+## 3. Application and Deployment
+
+The Winterhold Framework is the certified software core for deployments in:
+
+* **DAWNSTAR:** Certified robotic mobility agents.
+* **ESBERN:** High-precision manipulation systems.
+* **Cognitive Augmentation:** Localized Retrieval-Augmented Generation (RAG) systems (MNEMOSYNE) for memory prosthesis and anomaly detection (VESTA).
+
+### 3.1. Ecosystem Interoperability
+
+The architecture is designed to support secure, decoupled interoperability with specialized administrative systems, such as the Koalix CRM fork, **Arngeir**, maintaining a clear functional separation between critical life-safety and institutional management layers.
+
+---
+
+## 4. Institutional and Technical Contribution
+
+IA\_AUT\_ECO prioritizes collaboration with specialized expertise. We seek contributions that enhance the system's security profile and technical depth.
+
+* **Areas of Focus:** FreeBSD systems programming, Post-Quantum Cryptography implementation, ROS 2 Safety Layer development, and low-level embedded system optimization.
+* **Protocol:** All contributions are subject to rigorous security and architectural audit to uphold NIS2 compliance and critical safety rating.
