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.

An aggressive short-mode counterpart to the conservative bear specialist: shorting the weakest tokens by negative momentum on Binance USDⓈ-M perps, 2022 bear market POC

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.
