I deployed Open WebUI ChatGPT-style chat UI for every device on the LAN, and a shared RAG-over-MCP retrieval server that both the chat and the coding agent can attach to.

Running an open-weights coding agent entirely on the home LAN -- a spare box serves a Qwen3-Coder MoE over llama.cpp to laptops and phones around the house. Why the harness is Qwen-Code, and how a quantization sweep found the fastest model that still codes.

A 3-state Gaussian Hidden Markov Model identifies bear / ranging / bull regimes in BTC from a single causal feature -- drawdown from the running all-time high -- with median bear-posterior of 1.00 across calendar 2022 and exactly one Viterbi flip. Why drawdown beats log-return and log-price as the HMM observation.

Applying the Karpathy-style autoresearch loop to an HMM + per-regime GEM specialist + meta-allocator trading stack. Headline result from a 215-config / 18-hour run on 437 Binance + DefiLlama tokens, plus a scaled-down Python version over a 4-token bear-portfolio subset.
