+```
+
+## Log Categories
+
+### Application Logs
+Contains general application logging information, including startup, shutdown, and general operational messages.
+
+### Transaction Logs
+Records all transaction-related activities, including executed trades and identified arbitrage opportunities.
+
+### Event Logs
+Captures DEX event processing, including liquidity events and swap events. These logs are rotated when they reach a certain size.
+
+### Archived Logs
+Contains compressed historical logs that are retained for a specified period.
+
+### Monitoring Logs
+Stores periodic metrics and monitoring data.
+
+## Log Rotation
+
+Log rotation is managed by the `scripts/rotate-logs.sh` script, which:
+
+1. Compresses event logs when they exceed 100MB
+2. Moves compressed logs to the archived directory
+3. Removes archived logs older than 30 days
+
+## Log Management Commands
+
+To manually rotate logs:
+```bash
+./scripts/rotate-logs.sh
+```
+
+To view recent application logs:
+```bash
+tail -f logs/app/mev_bot.log
+```
+
+To view recent error logs:
+```bash
+tail -f logs/app/mev_bot_errors.log
+```
+
+To view recent transaction logs:
+```bash
+tail -f logs/transactions/mev_bot_transactions.log
+```
+
+## Log Retention Policy
+
+- Event logs: Compressed and archived when exceeding 100MB
+- Archived logs: Retained for 30 days
+- All other logs: No automatic rotation (managed by application)
+
+## Troubleshooting
+
+If you're experiencing issues with log management:

+
+**Audit Date:** September 13, 2025  
+**Project:** MEV Beta - Arbitrum L2 MEV Bot  
+**Version:** Latest commit (7dd5b5b)  
+**Auditor:** Claude Code Security Analyzer  
+
+### Overall Security Assessment: **MEDIUM RISK**
+
+The MEV bot codebase demonstrates good security awareness in key areas such as cryptographic key management and rate limiting. However, several critical vulnerabilities and architectural issues pose significant risks for production deployment, particularly in a high-stakes MEV trading environment.
+
+### Key Findings Summary:
+- **Critical Issues:** 6 findings requiring immediate attention
+- **High Risk Issues:** 8 findings requiring urgent remediation  
+- **Medium Risk Issues:** 12 findings requiring attention
+- **Low Risk Issues:** 7 findings for future improvement
+
+## Critical Issues (Immediate Action Required)
+
+### 1. **Channel Race Conditions Leading to Panic** ⚠️ CRITICAL
+**Location:** `/pkg/market/pipeline.go:170`, `/pkg/monitor/concurrent.go`  
+**Risk Level:** Critical - Production Halting  
+
+**Issue:** Multiple goroutines can close channels simultaneously, causing panic conditions:
+```go
+// Test failure: panic: send on closed channel
+// Location: pkg/market/pipeline.go:170
+```
+
+**Impact:** 
+- Bot crashes during operation, losing MEV opportunities
+- Potential financial loss due to incomplete transactions
+- Service unavailability
+
+**Recommendation:**
+- Implement proper channel closing patterns with sync.Once
+- Add channel state tracking before writes

+
+### 2. **Hardcoded API Keys in Configuration** ⚠️ CRITICAL
+**Location:** `/config/config.production.yaml`  
+**Risk Level:** Critical - Credential Exposure  
+
+**Issue:** Production configuration contains placeholder API keys that may be committed to version control:
+```yaml
+rpc_endpoint: "wss://arb-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_KEY"
+ws_endpoint: "wss://arbitrum-mainnet.infura.io/ws/v3/YOUR_INFURA_KEY"
+```
+
+**Impact:**
+- API key exposure if committed to public repositories
+- Unauthorized access to RPC services
+- Potential service abuse and cost implications
+
+**Recommendation:**
+- Remove all placeholder keys from configuration files
+- Implement mandatory environment variable validation
+- Add pre-commit hooks to prevent credential commits
+
+### 3. **Insufficient Input Validation on RPC Data** ⚠️ CRITICAL  
+**Location:** `/pkg/arbitrum/parser.go`, `/pkg/arbitrum/client.go`  
+**Risk Level:** Critical - Injection Attacks  
+
+**Issue:** Direct processing of blockchain data without proper validation:
+```go
+// No validation of transaction data length or content
+l2Message.Data = tx.Data()
+// Direct byte array operations without bounds checking
+interaction.TokenIn = common.BytesToAddress(data[12:32])
+```
+
+**Impact:**
+- Potential buffer overflow attacks
+- Invalid memory access leading to crashes
+- Possible code injection through crafted transaction data
+
+**Recommendation:**
+- Implement strict input validation for all RPC data
+- Add bounds checking for all byte array operations
+- Validate transaction data format before processing
+
+### 4. **Missing Authentication for Admin Endpoints** ⚠️ CRITICAL
+**Location:** `/config/config.production.yaml:95-103`  
+**Risk Level:** Critical - Unauthorized Access  
+
+**Issue:** Metrics and health endpoints exposed without authentication:
+```yaml
+metrics:
+  enabled: true
+  port: 9090
+  path: "/metrics"
+health:
+  enabled: true
+  port: 8080
+  path: "/health"
+```
+
+**Impact:**
+- Unauthorized access to bot performance metrics
+- Information disclosure about trading strategies
+- Potential DoS attacks on monitoring endpoints
+
+**Recommendation:**
+- Implement API key authentication for all monitoring endpoints
+- Add rate limiting to prevent abuse

+
+### 5. **Weak Private Key Validation** ⚠️ CRITICAL
+**Location:** `/pkg/security/keymanager.go:148-180`  
+**Risk Level:** Critical - Financial Loss  
+
+**Issue:** Private key validation only checks basic format but misses critical security validations:
+```go
+// Missing validation for key strength and randomness
+if privateKey.D.Sign() == 0 {
+    return fmt.Errorf("private key cannot be zero")
+}
+// No entropy analysis or weak key detection
+```
+
+**Impact:**
+- Acceptance of weak or predictable private keys
+- Potential key compromise leading to fund theft
+- Insufficient protection against known weak keys
+
+**Recommendation:**
+- Implement comprehensive key strength analysis
+- Add entropy validation for key generation
+- Check against known weak key databases
+
+### 6. **Race Condition in Rate Limiter** ⚠️ CRITICAL
+**Location:** `/internal/ratelimit/manager.go:60-71`  
+**Risk Level:** Critical - Service Disruption  
+
+**Issue:** Rate limiter map operations lack proper synchronization:
+```go
+// Read-write race condition possible
+lm.mu.RLock()
+limiter, exists := lm.limiters[endpointURL]
+lm.mu.RUnlock()
+// Potential for limiter to be modified between check and use
+```
+
+**Impact:**
+- Rate limiting bypass leading to RPC throttling
+- Bot disconnection from critical services
+- Unpredictable behavior under high load
+
+**Recommendation:**
+- Extend lock scope to include limiter usage
+- Implement atomic operations where possible

+# MEV Bot Organization Summary
+
+This document summarizes the organization improvements made to the MEV Bot project, including documentation, logs, and codebase structure.
+
+## Documentation Organization
+
+The documentation has been reorganized into a clear, categorized structure:
+
+```
+docs/
+├── 1_getting_started/          # Quick start guides and setup
+├── 2_architecture/             # System design and architecture
+├── 3_core_packages/            # Detailed package documentation
+├── 4_application/              # Main application documentation
+├── 5_development/              # Development guides and practices
+├── 6_operations/               # Production and operations
+├── 7_reference/                # Technical reference materials
+├── 8_reports/                  # Project reports and analysis
+├── INDEX.md                    # Main documentation index
+└── TABLE_OF_CONTENTS.md        # Detailed navigation guide
+```
+
+Each category now has an overview document that explains the contents and provides context. All existing documentation files have been moved to their appropriate categories.
+
+## Logs Organization
+
+The logs have been reorganized into a structured directory system with rotation and categorization:
+
+```
+logs/
+├── app/                        # Application logs
+├── transactions/               # Transaction-related logs
+├── events/                     # Event processing logs
+├── archived/                   # Archived/compressed logs
+└── monitoring/                 # Monitoring and metrics
+```
+
+A log rotation script has been created at `scripts/rotate-logs.sh` to manage event logs when they exceed 100MB, with a retention policy of 30 days for archived logs.
+
+## Codebase Organization
+
+The codebase structure was already well-organized following Go best practices:
+
+```
+.
+├── cmd/                        # Main applications
+├── config/                     # Configuration files
+├── internal/                   # Private application code
+├── pkg/                        # Public library code
+├── docs/                       # Documentation (as organized above)
+├── logs/                       # Log files (as organized above)
+├── scripts/                    # Build and utility scripts
+└── test/                       # Integration and system tests
+```
+
+## Key Improvements
+
+1. **Improved Documentation Navigation**: Clear categorization makes it easier to find relevant documentation
+2. **Structured Logs**: Organized log directories with rotation and retention policies
+3. **Maintained Codebase Structure**: Kept the existing well-organized codebase structure
+4. **Updated References**: All documentation references in README and other files have been updated
+5. **Log Management**: Added automated log rotation and cleanup
+
+## Next Steps
+
+1. **Monitor Log Rotation**: Ensure the log rotation script works as expected in production
+2. **Update Documentation**: Continue to maintain the organized documentation structure as new documents are added
+3. **Review periodically**: Periodically review the organization structure to ensure it continues to meet project needs

-# MEV Bot Security Audit Report
+# 🔒 MEV Bot Security Audit Report
+
+**Date:** September 20, 2025
+**Auditor:** Claude Security Analysis
+**Version:** 1.0.0
+**Status:** Critical Issues Identified

 ## Executive Summary

-**Audit Date:** September 13, 2025  
-**Project:** MEV Beta - Arbitrum L2 MEV Bot  
-**Version:** Latest commit (7dd5b5b)  
-**Auditor:** Claude Code Security Analyzer  
+This comprehensive security audit of the MEV Bot identified **146 HIGH severity issues** and multiple critical security vulnerabilities that require immediate attention. The bot handles financial transactions on Arbitrum and must be secured before production deployment.

-### Overall Security Assessment: **MEDIUM RISK**
+## 🚨 Critical Findings Summary

-The MEV bot codebase demonstrates good security awareness in key areas such as cryptographic key management and rate limiting. However, several critical vulnerabilities and architectural issues pose significant risks for production deployment, particularly in a high-stakes MEV trading environment.
+| Severity | Count | Status |
+|----------|-------|--------|
+| CRITICAL | 12 | ❌ Unresolved |
+| HIGH | 146 | ❌ Unresolved |
+| MEDIUM | 28 | ⚠️ Partial |
+| LOW | 15 | ✅ Acceptable |

-### Key Findings Summary:
- **Critical Issues:** 6 findings requiring immediate attention
- **High Risk Issues:** 8 findings requiring urgent remediation  
- **Medium Risk Issues:** 12 findings requiring attention
- **Low Risk Issues:** 7 findings for future improvement
+## 1. Code Security Analysis

-## Critical Issues (Immediate Action Required)
+### 1.1 Integer Overflow Vulnerabilities (HIGH)

-### 1. **Channel Race Conditions Leading to Panic** ⚠️ CRITICAL
-**Location:** `/pkg/market/pipeline.go:170`, `/pkg/monitor/concurrent.go`  
-**Risk Level:** Critical - Production Halting  
+**Finding:** Multiple instances of unsafe integer conversions that can cause overflow:

-**Issue:** Multiple goroutines can close channels simultaneously, causing panic conditions:
 ```go
-// Test failure: panic: send on closed channel
-// Location: pkg/market/pipeline.go:170
+// pkg/arbitrum/token_metadata.go:245
+return uint8(v.Uint64()), nil  // uint64 -> uint8 overflow
+
+// pkg/validation/pool_validator.go:657
+return token0, token1, uint32(fee), nil  // uint64 -> uint32 overflow
+
+// pkg/arbitrum/protocol_parsers.go:multiple locations
+Fee: uint32(fee)  // Multiple unsafe conversions
 ```

-**Impact:** 
- Bot crashes during operation, losing MEV opportunities
- Potential financial loss due to incomplete transactions
- Service unavailability
+**Risk:** Integer overflow can lead to incorrect calculations, potentially causing:
+- Wrong price calculations
+- Incorrect fee assessments
+- Exploitable arbitrage calculations

-**Recommendation:**
- Implement proper channel closing patterns with sync.Once
- Add channel state tracking before writes
- Implement graceful shutdown mechanisms
-
-### 2. **Hardcoded API Keys in Configuration** ⚠️ CRITICAL
-**Location:** `/config/config.production.yaml`  
-**Risk Level:** Critical - Credential Exposure  
-
-**Issue:** Production configuration contains placeholder API keys that may be committed to version control:
-```yaml
-rpc_endpoint: "wss://arb-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_KEY"
-ws_endpoint: "wss://arbitrum-mainnet.infura.io/ws/v3/YOUR_INFURA_KEY"
-```
-
-**Impact:**
- API key exposure if committed to public repositories
- Unauthorized access to RPC services
- Potential service abuse and cost implications
-
-**Recommendation:**
- Remove all placeholder keys from configuration files
- Implement mandatory environment variable validation
- Add pre-commit hooks to prevent credential commits
-
-### 3. **Insufficient Input Validation on RPC Data** ⚠️ CRITICAL  
-**Location:** `/pkg/arbitrum/parser.go`, `/pkg/arbitrum/client.go`  
-**Risk Level:** Critical - Injection Attacks  
-
-**Issue:** Direct processing of blockchain data without proper validation:
+**Remediation:**
 ```go
-// No validation of transaction data length or content
-l2Message.Data = tx.Data()
-// Direct byte array operations without bounds checking
-interaction.TokenIn = common.BytesToAddress(data[12:32])
-```
-
-**Impact:**
- Potential buffer overflow attacks
- Invalid memory access leading to crashes
- Possible code injection through crafted transaction data
-
-**Recommendation:**
- Implement strict input validation for all RPC data
- Add bounds checking for all byte array operations
- Validate transaction data format before processing
-
-### 4. **Missing Authentication for Admin Endpoints** ⚠️ CRITICAL
-**Location:** `/config/config.production.yaml:95-103`  
-**Risk Level:** Critical - Unauthorized Access  
-
-**Issue:** Metrics and health endpoints exposed without authentication:
-```yaml
-metrics:
-  enabled: true
-  port: 9090
-  path: "/metrics"
-health:
-  enabled: true
-  port: 8080
-  path: "/health"
-```
-
-**Impact:**
- Unauthorized access to bot performance metrics
- Information disclosure about trading strategies
- Potential DoS attacks on monitoring endpoints
-
-**Recommendation:**
- Implement API key authentication for all monitoring endpoints
- Add rate limiting to prevent abuse
- Consider VPN or IP whitelisting for sensitive endpoints
-
-### 5. **Weak Private Key Validation** ⚠️ CRITICAL
-**Location:** `/pkg/security/keymanager.go:148-180`  
-**Risk Level:** Critical - Financial Loss  
-
-**Issue:** Private key validation only checks basic format but misses critical security validations:
-```go
-// Missing validation for key strength and randomness
-if privateKey.D.Sign() == 0 {
-    return fmt.Errorf("private key cannot be zero")
+// Safe conversion with bounds checking
+func safeUint32(val uint64) (uint32, error) {
+    if val > math.MaxUint32 {
+        return 0, fmt.Errorf("value %d exceeds uint32 max", val)
+    }
+    return uint32(val), nil
 }
-// No entropy analysis or weak key detection
 ```

-**Impact:**
- Acceptance of weak or predictable private keys
- Potential key compromise leading to fund theft
- Insufficient protection against known weak keys
+### 1.2 Hardcoded Sensitive Information (CRITICAL)

-**Recommendation:**

-
-### 6. **Race Condition in Rate Limiter** ⚠️ CRITICAL
-**Location:** `/internal/ratelimit/manager.go:60-71`  
-**Risk Level:** Critical - Service Disruption  
-
-**Issue:** Rate limiter map operations lack proper synchronization:
+**Finding:** RPC endpoints hardcoded in source:
 ```go
-// Read-write race condition possible
-lm.mu.RLock()
-limiter, exists := lm.limiters[endpointURL]
-lm.mu.RUnlock()
-// Potential for limiter to be modified between check and use
+// pkg/arbitrage/service.go:994-995
+RPCEndpoint: "wss://arbitrum-mainnet.core.chainstack.com/f69d14406bc00700da9b936504e1a870",
+WSEndpoint:  "wss://arbitrum-mainnet.core.chainstack.com/f69d14406bc00700da9b936504e1a870",
 ```

-**Impact:**
- Rate limiting bypass leading to RPC throttling
- Bot disconnection from critical services
- Unpredictable behavior under high load
+**Risk:**
+- Exposed API keys in source control
+- Rate limiting bypass detection
+- Potential service disruption if keys are revoked

-**Recommendation:**
