docs: rebuild KB in OKF v0.1 with live-verified facts

Copy of the legacy ~/.pi/agent/docs tree rebuilt as the command-center
knowledge base: concept files promoted to path identity, index listings
stripped of frontmatter, all wikilinks/relative links resolved, every
checkable claim verified against the live fleet (Dankserver = Ryzen 7
7700X + RTX 3090; Strix Halo is Dankclaw), unverifiable claims tagged.
kb-lint exits 0.

+
+# Installation
+
+## 1. Clone and Build llama.cpp
+
+```bash
+cd ~/GitPackages
+git clone https://github.com/ggerganov/llama.cpp
+cd llama.cpp
+cmake -B build -DLLAMA_CUDA=ON
+cmake --build build --config Release
+```
+
+## 2. Download the Model
+
+```bash
+mkdir -p ~/models/ornith
+cd ~/models/ornith
+
+# For 9B model (faster, less memory)
+wget https://huggingface.co/ornith-ai/Ornith-1.0-9B-GGUF/resolve/main/ornith-1.0-9b-Q4_K_M.gguf
+
+# OR for 35B MoE model (better performance, more memory)
+wget https://huggingface.co/ornith-ai/Ornith-1.0-35B-GGUF/resolve/main/ornith-1.0-35b-Q4_K_M.gguf
+```
+
+## 3. Start the Server
+
+**For 9B model with full GPU offload (8GB+ VRAM):**
+```bash
+cd ~/GitPackages/llama.cpp
+./build/bin/llama-server \
+  -m ~/models/ornith/ornith-1.0-9b-Q4_K_M.gguf \
+  -c 262144 \
+  -ngl 99 \
+  --host 0.0.0.0 \
+  --port 8080
+```
+
+**For 35B MoE model with partial GPU offload (8GB VRAM example):**
+```bash
+cd ~/GitPackages/llama.cpp
+./build/bin/llama-server \
+  -m ~/models/ornith/ornith-1.0-35b-Q4_K_M.gguf \
+  -c 131072 \
+  -ngl 12 \
+  --host 0.0.0.0 \
+  --port 8080
+```
+
+**Key Parameters:**
+- `-m`: Path to GGUF model file
+- `-c` / `--ctx-size`: Context window size (131072 or 262144)
+- `-ngl` / `--n-gpu-layers`: Number of layers to offload to GPU
+  - 99 = all layers
+  - Lower values = more CPU inference
+- `--host`: Bind address (0.0.0.0 for all interfaces, 127.0.0.1 for local only)
+- `--port`: Server port (default 8080)
+
+## 4. Verify Server is Running
+
+```bash
+curl http://localhost:8080/health
+# Expected: {"status":"ok"}
+```
+
+## 5. Test the Model
+
+```bash
+curl -s http://localhost:8080/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "frank-default-local",
+    "messages": [
+      {"role": "user", "content": "Hello, what is 2+2?"}
+    ],
+    "max_tokens": 150,
+    "temperature": 0.7
+  }' | jq .
+```
