   ```bash
   USE_ADAPTIVE_LEVERAGE=true
-  HIGH_QUALITY_LEVERAGE=5      # 5x for quality ≥95 LONGs, ≥90 SHORTs
-  LOW_QUALITY_LEVERAGE=1       # 1x for borderline quality (Q90-94 LONGs, Q80-89 SHORTs)

   ```
-- **Rationale:** User chose "option 1" (quality-based adaptive leverage) with 5x instead of 6x for "less risk"
+- **Settings UI (Dec 1, 2025 - FULLY IMPLEMENTED):**
+  * Web interface at http://localhost:3001/settings
+  * **Adaptive Leverage Section** with 5 configurable fields:
+    - Enable/Disable toggle (USE_ADAPTIVE_LEVERAGE)
+    - High Quality Leverage (10x default)
+    - Low Quality Leverage (5x default)
+    - **LONG Quality Threshold (95 default)** - independent control
+    - **SHORT Quality Threshold (90 default)** - independent control
+  * **Dynamic Collateral Display:** Fetches real-time balance from Drift account
+  * **Position Size Calculator:** Shows notional positions for each leverage tier
+  * **API Endpoint:** GET /api/drift/account-health returns { totalCollateral, freeCollateral, totalLiability, marginRatio }
+  * **Real-time Updates:** Collateral fetched on page load via React useEffect
+  * **Fallback:** Uses $560 if Drift API unavailable
 - **Direction-Specific Thresholds:**
-  * LONGs: Quality ≥95 → 5x, Quality 90-94 → 1x
-  * SHORTs: Quality ≥90 → 5x, Quality 80-89 → 1x
+  * LONGs: Quality ≥95 → 10x, Quality 90-94 → 5x
+  * SHORTs: Quality ≥90 → 10x, Quality 80-89 → 5x
   * Lower quality than thresholds → blocked by execute endpoint
