The original title is "The Second Brain They Can't Subpoena: Local RAG on a Pi 5"

Short summary

Local RAG on Pi 5 lets you keep your extended mind private and portable—no cloud landlords, no subpoenas, no epistemic pollution. The author synthesizes extended-mind philosophy with a production stack: Qdrant, Ollama, quantized llama3.1, Hailo-8 acceleration, LUKS2 encryption, and detailed hardware specs. RAG outperforms fine-tuning for personal knowledge because it preserves provenance, enables daily mutability, supports metadata composability, and stays portable on a $200 device.

• •Local RAG eliminates cloud dependencies: queries never leave your LAN, data isn't discoverable in legal proceedings, and you avoid epistemic pollution from shared model training
• •Production stack includes Qdrant (vector store), Ollama (model serving), nomic embeddings (ARM-optimized), Hailo-8 acceleration (embedded inference), and LUKS2/Argon2id encryption
• •Concrete hardware blueprint: Pi 5 8GB, NVMe HAT, 1TB SSD, Hailo-8, passive heatsink, USB-C battery—4-12W power draw, full day runtime on 20Ah bank
