Galaxy Z Fold6 as a local inference node — llama.cpp/Vulkan, homelab telemetry, SHA-256 model verification

Built a small Android app called Pocket Node that runs llama.cpp inference on-device. Here's what it actually does and what it doesn't. **What it does** * Loads a GGUF model (SmolLM3 Q4_0, ~1.1B params) directly on the Fold6 * Uses the Vulkan/OpenCL backend via llama.cpp — not CPU-only * Streams tok
