+    *   **On-Chain Layer**: Reconstructs UTXO sets. Computes Young-to-Old Supply Velocity ($V_{\text{supply}}$) and Adjusted SOPR (aSOPR), tracking STH/LTH-SOPR at the 155-day boundary.
+    *   **Perpetual Derivatives WebSockets**: Computes Open Interest-to-Market Cap Ratio ($\Theta_t$), Implied Liquidation Distance ($D_{\text{liq}}$) using Gaussian smoothing kernels, and Rolling Z-score of compounded 8h funding rates ($Z_F$).
+    *   **Microstructure Pipeline**: Splits Cumulative Volume Delta (CVD) into institutional vs. retail cohorts to evaluate Divergence ($Div_{\text{CVD}}$), and estimates rolling Kyle's Lambda ($\lambda_{\text{Kyle}}$) price impact.
+*   **Stationarity & Memory Transformation**: Applied Dickey-Fuller (ADF) optimal $d^*$ search (target p-value < 0.01) for Fixed-Width Fractional Differentiation (FFD) and causal Rolling Median Absolute Deviation (MAD) scaling in [pipeline.py](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/backend/core/pipeline.py).
+*   **Markov-Switching GJR-GARCH Volatility Regime Router**: Integrated Student-t innovations MS-GJR-GARCH regime gated matrices routing microstructure features during Calm states, and prioritizing On-Chain/Derivatives features during Turbulent states.
+*   **PIMP & Boruta Pruning Filters**: Implemented Permutation Feature Importance (PFI) vs. randomized null distributions ($M=50$ target permutations, significance $p < 0.05$) and Boruta shadow feature pruning.
+*   **Two-Stage Selective Inference ML Engine**: Standardized XGBoost/RF directional classifiers (Stage 1) gated by secondary correctness Reliability Meta-Learners (Stage 2) with strict execution confidence thresholds ($\theta_{\text{conf}} = 0.55$) triggering Zero-Exposure states (`0.5` probabilities) upon failure.
