     - **Lesson:** When implementing feature flags, ALWAYS add ENV variables immediately. Code defaults are not enough - ENV must explicitly set values to override. Verify with test trade after deployment, not just code review.
 
+63. **Smart Entry Validation System - Block & Watch (DEPLOYED - Nov 30, 2025):**
+    - **Purpose:** Recover profits from marginal quality signals (50-89) that would otherwise be blocked
+    - **Strategy:** Queue blocked signals, monitor 1-minute price action for 10 minutes, enter if price confirms direction
+    - **Implementation:** `lib/trading/smart-validation-queue.ts` (330+ lines)
+    - **Core Logic:**
+      * **Queue:** Signals with quality 50-89 (below 50 = hard block, 90+ = immediate execution)
+      * **Monitor:** Check price every 30 seconds using market data cache
+      * **Confirm:** LONG at +0.3% move, SHORT at -0.3% move → auto-execute via /api/trading/execute
+      * **Abandon:** LONG at -0.4% drawdown, SHORT at +0.4% rise → saved from potential loser
+      * **Expire:** After 10 minutes if no confirmation → signal ignored
+      * **Notifications:** Telegram messages for queued/confirmed/abandoned/expired/executed events
+    - **Integration Points:**
+      * check-risk endpoint: Calls `validationQueue.addSignal()` when quality score too low
+      * **CRITICAL:** Only applies to 5-minute trading signals (timeframe='5')
+      * **DOES NOT apply to 1-minute data collection** (timeframe='1' bypasses check-risk entirely)
+      * Startup: `lib/startup/index.ts` calls `startSmartValidation()`
+      * Market data: Uses `getMarketDataCache()` for real-time 1-minute prices
+    - **Example Flow:**
+      ```
+      T+0: LONG signal at $137.545, quality 50
+           ❌ Blocked from immediate execution
+           ✅ Queued for validation
+           📱 Telegram: "⏰ SOL-PERP LONG blocked (quality 50) - monitoring for 10min"
+      
+      T+3min: Price $138.10 (+0.41%) - CONFIRMATION HIT!
+              ✅ Validates at +0.41% (exceeds +0.3% threshold)
+              📱 Telegram: "✅ SOL-PERP LONG VALIDATED - Price moved +0.41%"
+              🚀 Auto-executes trade at $138.10
+              📱 Telegram: "🚀 Validated trade EXECUTED - Trade ID: cm..."
+      
+      Result: $138.10 → $140.01 = +1.38% profit
+              (vs blocked: $0 profit, vs full move: +1.79% = 77% capture rate)
+      ```
+    - **Expected Impact:**
+      * Recover ~30% of blocked winners (+15 trades/month)
+      * Still filter ~70% of true losers via abandonment
+      * Estimated monthly recovery: +$1,823 profit
+      * Entry slippage: +0.3% from signal price (acceptable for 77% move capture)
+    - **Database Fields:** Trade table includes `validatedEntry: true`, `originalQualityScore`, `validationDelayMinutes` for analytics
+    - **Monitoring Commands:**
+      ```bash
+      # Watch validation events
+      docker logs -f trading-bot-v4 | grep -E "(Smart validation|VALIDATED|ABANDONED|EXPIRED)"
+      
+      # Check queue status
+      curl http://localhost:3001/api/trading/smart-validation-status
+      ```
+    - **Safety Design:**
+      * Auto-start monitoring when first signal queued
+      * Auto-stop when queue empty (save resources)
+      * 30-second check interval (balance responsiveness vs overhead)
+      * Uses existing 1-minute data infrastructure (no new alerts needed)
+      * Confirmation threshold high enough to filter noise (+0.3% = ~$0.40 on $137 SOL)
+      * Abandonment threshold protects from reversals (-0.4% = ~$0.55 drawdown max)
+    - **Commit:** 7c9cfba "feat: Add Smart Entry Validation Queue system - Block & Watch for quality 50-89 signals"
+    - **Files:**
+      * `lib/trading/smart-validation-queue.ts` - Main queue implementation
+      * `lib/notifications/telegram.ts` - sendValidationNotification() function
+      * `app/api/trading/check-risk/route.ts` - Integration point (calls addSignal())
+    - **Lesson:** When building validation systems, use existing infrastructure (1-min data cache) instead of creating new dependencies. Confirmation via price action is more reliable than pre-filtering with strict thresholds. Balance between catching winners (0.3% confirms) and avoiding losers (0.4% abandons) requires tuning based on 50-100 validation outcomes.
