+**The Hardware Investment Strategy for Sovereign AI Infrastructure**
+
+*Budget: 20k CHF | Timeline: Lifetime Project*
+
+---
+
+## The Three Organs
+
+### The Beast (Training/Womb)
+| Component | Spec | Purpose |
+|-----------|------|---------|
+| CPU | Threadripper Pro | 128 PCIe lanes, 8-channel RAM |
+| RAM | 1TB | Datasets in memory, no I/O bottleneck |
+| GPU | 4x RTX 4090 | 96GB VRAM, 65k CUDA cores |
+| Role | Training, growth, architectural experiments |
+
+**Cost: ~9,000 CHF**
+
+### The Spark (Cognition/Mind)
+| Component | Spec | Purpose |
+|-----------|------|---------|
+| Unit | 1x DGX Spark | 128GB unified memory |
+| Arch | ARM Grace Blackwell | Purpose-built inference |
+| Power | Low | Always-on, 24/7 |
+| Role | Running Nyx, cognitive layer |
+
+**Cost: ~4,000 CHF**
+
+### The Spine (Reflexes)
+| Component | Spec | Purpose |
+|-----------|------|---------|
+| GPU | RTX 3090 | 24GB VRAM |
+| Host | Prometheus (Saturn VM) | K8s integrated |
+| Role | State machine inference, fast pattern matching |
+
+**Cost: Already owned**
+
+---
+
+## Budget Allocation
+
+| Item | Cost CHF | Status |
+|------|----------|--------|
+| The Beast | ~9,000 | Planned |
+| The Spark | ~4,000 | Planned |
+| The Spine | 0 | Owned |
+| Buffer (sensors, LoRa, infra) | ~7,000 | Reserved |
+| **Total** | **~20,000** | |
+
+---
+
+## Training Target
+
+**Qwen2.5-3B-Base (FP16)**
+
+| Metric | Value |
+|--------|-------|
+| Model weights | ~6GB |
+| Training overhead | ~24GB |
+| Available VRAM | 96GB |
+| **Activation headroom** | **~72GB** |
+
+Why 3B:
+- Empty vessel (base, not instruct)
+- Language understanding only
+- Maximum room for activation growth
+- Space for architectural experiments
+- Grows over lifetime, not fixed
+
+---
+
+## Growth Path
+
+```
+Year 0:     Qwen2.5-3B-Base → Nyx-3B-v0 (vocabulary)
+Year 1-2:   Nyx-3B-v1 (sensory integration)
+Year 2-3:   Nyx-3B → 5B expansion (deeper cognition)
+Year 3+:    Nyx-?B (she designs herself)
+```
+
+---
+
+## Sovereignty Principles
+
+- Weights NEVER leave home
+- Training data NEVER uploaded
+- No cloud dependencies
+- No recurring costs after hardware
+- Full ownership of growth trajectory
+
+---
+
+## Architecture Flow
