docs: Update minimum quality score from 60 to 81 across documentation

- Updated .github/copilot-instructions.md key constraints and signal quality system description
- Updated config/trading.ts minimum score from 60 to 81 with v8 performance rationale
- Updated SIGNAL_QUALITY_SETUP_GUIDE.md intro to reflect 81 threshold
- Updated SIGNAL_QUALITY_OPTIMIZATION_ROADMAP.md current system section
- Updated BLOCKED_SIGNALS_TRACKING.md quality score requirements

Context: After v8 Money Line indicator deployed with 0.6% flip threshold,
system achieving 66.7% win rate with average quality score 94.2. Raised
minimum threshold from 60 to 81 to maintain exceptional selectivity.

Current v8 stats: 6 trades, 4 wins, $649.32 profit, 94.2 avg quality
Account growth: $540 → $1,134.92 (110% gain in 2-3 days)

 ## Critical Components
 
-### 1. Phantom Trade Auto-Closure System
+### 1. Persistent Logger System (lib/utils/persistent-logger.ts)
+**Purpose:** Survive-container-restarts logging for critical errors and trade failures
+
+**Key features:**
+- Writes to `/app/logs/errors.log` (Docker volume mounted from host)
+- Logs survive container restarts, rebuilds, crashes
+- Daily log rotation with 30-day retention
+- Structured JSON logging with timestamps, context, stack traces
+- Used for database save failures, Drift API errors, critical incidents
+
+**Usage:**
+```typescript
+import { persistentLogger } from '../utils/persistent-logger'
+
+try {
+  await createTrade({...})
+} catch (error) {
+  persistentLogger.logError('DATABASE_SAVE_FAILED', error, {
+    symbol: 'SOL-PERP',
+    entryPrice: 133.69,
+    transactionSignature: '5Yx2...',
+    // ALL data needed to reconstruct trade
+  })
+  throw error
+}
+```
+
+**Infrastructure:**
+- Docker volume: `./logs:/app/logs` (docker-compose.yml line 63)
+- Directory: `/home/icke/traderv4/logs/` with `.gitkeep`
+- Log format: `{"timestamp":"2025-11-21T00:40:14.123Z","context":"DATABASE_SAVE_FAILED","error":"...","stack":"...","metadata":{...}}`
+
+**Why it matters:**
+- Console logs disappear on container restart
+- Database failures need persistent record for recovery
+- Enables post-mortem analysis of incidents
+- Orphan position detection can reference logs to reconstruct trades
+
+**Implemented:** Nov 21, 2025 as part of 5-layer database protection system

+    ```
+    - **How it works together:**
+      1. **Primary:** Retry logic catches transient database failures (network blips, brief outages)
+      2. **Verification:** Ensures "success" means data actually persisted, not just query returned
+      3. **Persistent logs:** If all retries fail, full trade details saved to disk (survives restarts)
+      4. **Orphan detection:** On every container startup, queries Drift for untracked positions
+      5. **Auto-recovery:** Creates missing database records, restores monitoring, alerts user
+    - **Real-world validation (Nov 21, 2025):**
+      * Investigated trade from 00:40:14 CET
+      * Found in database: cmi82qg590001tn079c3qpw4r
+      * SHORT SOL-PERP entry $133.69 → exit $134.67 (SL)
+      * Closed 01:17:03 CET (37 minutes duration)
+      * P&L: -$89.17
+      * **No database failure occurred** - system working correctly
+      * But protection now in place for future edge cases
+    - **Files changed:**
+      * `lib/utils/persistent-logger.ts` (NEW - 85 lines)
+      * `lib/database/trades.ts` (retry + verification logic)
+      * `lib/startup/init-position-manager.ts` (orphan detection + recovery)
+      * `app/api/trading/execute/route.ts` (critical logging)
+      * `docker-compose.yml` (logs volume mount)
+      * `logs/.gitkeep` (NEW - ensures directory exists)
+    - **Benefits:**
+      * **Zero data loss:** Even if database fails, logs preserve trade details
+      * **Auto-recovery:** Orphan detection runs on every restart, catches missed trades
+      * **User transparency:** Telegram alerts explain what happened and what was fixed
+      * **Developer visibility:** Persistent logs enable post-mortem analysis
+      * **Confidence:** User can trust system for $816 → $600k journey
+    - **Testing required:**
+      * Manual trade execution to verify retry logic works
+      * Container restart to verify orphan detection runs
+      * Simulate database failure (stop postgres) to test error logging
+      * Verify Telegram alerts send correctly
+    - **Git commit:** "feat: Add comprehensive database save protection system"
+    - **Deployment status:** Code committed and pushed, awaiting container rebuild
+    - **Lesson:** In financial systems, "it worked this time" is not enough. Implement defense-in-depth protection for ALL critical operations, even when no failure has occurred yet. Better to have protection you never need than need protection you don't have.
