    *   *Accordion Matrix*: Each log row is expandable via Chevron toggle, displaying the individual model prediction direction and success/failure correctness status checkmarks upon resolution.
    *   *Multi-Accuracy Tracking*: Shows distinct columns for `T+1 Acc`, `T+5 Acc`, and `T+10 Acc` rather than a single aggregated metric.
    *   *Global Performance Metrics Panel*: Mounted below the feedback loop, presenting Horizon Efficiency (Section A) and Estimator Hit Distribution (Section B) dynamically evaluated from `localStorage` logs.
+    *   *Regime Status Indicator*: Renders glassmorphic conditional badges in the header of the Walk-Forward Radar based on `"activeRegime"` in the JSON payload (1 for Calm, 2 for Turbulent, 3 for Churn).
 *   **Quant Python Pipeline (`pipeline.py`)**:
    *   *Intermarket Sentiment Ingestion*: Fetches daily close values for Nasdaq Composite (`^IXIC`), Gold Spot (`GC=F`), VIX (`^VIX`), and Crypto Fear & Greed (Alternative.me API). Incorporates automatic forward-fill (`ffill()`) and backward-fill (`bfill()`) to process data gaps.
-    *   *Feature selection gateway*: Restricts features passed to the SVM and MLP estimators to those selected by a Random Forest feature importance selector (`SelectFromModel` with threshold `"mean"`), protecting non-linear algorithms from overfitting.
+    *   *Feature selection gateway*: Restricts features passed to the estimators to those selected by Boruta & PIMP filters, while explicitly prioritizing and bypassing pruning for all high-alpha metrics (`v_supply`, `asopr`, `sth_sopr`, `lth_sopr`, `theta`, `squeeze_risk`, `d_liq`, `f_comp`, `z_f`, `z_f_squeeze_trigger`, `cvd_inst`, `cvd_ret`, `div_cvd`, `lambda_kyle`).
+    *   *Dynamic Meta-Learner Calibrator*: Replaces the static $\theta_{\text{conf}} = 0.55$ with a dynamic calibration threshold computed as the mean training correctness probability (`np.mean(train_r_probs)`) inside each model loop, successfully resolving the 50% entropy block.
+    *   *Defensive Class Array Check*: Detects if the target classes array has a size smaller than 2, applying deterministic training probability fallbacks.

+## [2026-06-17] - Volatility Regime Badging & Selective Inference Calibrator (#ISSUE-027-REGIME-UI)
+
+### Added
+*   **Vol Regime Status Badges (CryptoDemo.tsx)**: Mounted high-visibility, glassmorphic conditional status badges adjacent to the "Explain Calibration" button in the Walk-Forward Ensemble Radar header. Dynamically renders:
+    *   `🟢 REGIME: CALM (MICROSTRUCTURE MODE)` for Regime 1 (Calm).
+    *   `🚨 REGIME: TURBULENT (LIQUIDATION CASCADE)` (flashing/pulsing) for Regime 2 (Turbulent).
+    *   `🟡 REGIME: MEAN-REVERTING CHURN` for Regime 3 (Mean-Reverting Churn).
+*   **Ensemble Active Regime Ingestion**: Bound `activeRegime` in the `fetchEnsemble` routine of [CryptoDemo.tsx](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/components/modules/crypto/CryptoDemo.tsx) to read `"activeRegime"` from the JSON output of the python pipeline.
+*   **Active Volatility Regime Export**: Overhauled [pipeline.py](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/backend/core/pipeline.py) to return `active_regime` from `train_and_forecast()` and write `"activeRegime": int(active_regime) + 1` (re-indexing Calm=0 to 1, Turbulent=1 to 2) inside the main JSON output payload (`ensemble_predictions.json`).
+*   **High-Alpha Feature Selector Prioritization**: Configured the Boruta & PIMP feature selection filters in [pipeline.py](file:///c:/Users/jannr/.gemini/antigravity/scratch/investment-sandbox/backend/core/pipeline.py) to explicitly prioritize and bypass pruning for all high-alpha metrics (`v_supply`, `asopr`, `sth_sopr`, `lth_sopr`, `theta`, `squeeze_risk`, `d_liq`, `f_comp`, `z_f`, `z_f_squeeze_trigger`, `cvd_inst`, `cvd_ret`, `div_cvd`, `lambda_kyle`), ensuring they are always routed to the estimators.
+*   **Dynamic Meta-Learner Calibrator**: Calibrated the Stage 2 Reliability Meta-Learner execution threshold ($\theta_{\text{conf}}$) dynamically against the empirical mean training correctness probability (`np.mean(train_r_probs)`) inside each model loop, successfully resolving the 50.0% zero-exposure entropy block.
+*   **Defensive Class Array Check**: Guarded against `IndexError` in the Meta-Learner confidence calculator by checking `len(meta_clf.classes_) >= 2`, providing stable execution fallbacks if the training correctness labels are uniform.
