 ### 🚨 NEVER COMMIT DIRECTLY TO MASTER/MAIN BRANCH 🚨
 
 - **This is the most important rule - NEVER modify code directly on main or master branch**
+- **ALL CHANGES MUST GO THROUGH PULL REQUESTS - NO EXCEPTIONS**
 - **Always work on feature branches and use pull requests for all changes**
 - **Any direct commits to master/main branch are strictly forbidden**
+- **Pull requests are the ONLY way to merge code to main branch**
 - Before starting any development, always:
   1. `git checkout main` (switch to main branch)
   2. `git pull` (get latest changes)
   3. `git checkout -b feat/your-feature-name` (create and switch to feature branch)

+   7. **Create a pull request for code review - THIS IS THE ONLY WAY TO MERGE TO MAIN**
+   8. **Wait for PR approval before merging - NEVER merge your own PRs without review**
 - Use descriptive branch names following the pattern: `feat/feature-name`, `fix/issue-name`, `refactor/component-name`, etc.
 - **Double-check current branch before ANY commit: `git branch` to ensure you're NOT on main/master**
-- Ensure all changes are made on feature branches and merged through pull requests
+- **Pull Request Requirements:**
+  - All changes must be submitted via PR regardless of size or urgency
+  - PRs must include comprehensive description and testing information
+  - PRs must pass all CI/CD checks before merging
+  - PRs require at least one approval from code reviewers
+  - Even hotfixes and emergency changes must go through PR process
+- **Enforcement:**
+  - Main branch should be protected with branch protection rules
+  - Direct pushes to main should be blocked by repository settings
+  - Any accidental direct commits to main must be immediately reverted via PR
 
 #### Development Workflow
 
+## 🎯 **Core Development Principles**
+
+- **🔴 Every change must be precise - don't modify unless you're confident**
+  - Carefully analyze code logic and ensure complete understanding before making changes
+  - When uncertain, prefer asking users or consulting documentation over blind modifications
+  - Use small iterative steps, modify only necessary parts at a time
+  - Evaluate impact scope before changes to ensure no new issues are introduced
+
+- **🚀 GitHub PR creation prioritizes gh command usage**
+  - Prefer using `gh pr create` command to create Pull Requests
+  - Avoid having users manually create PRs through web interface
+  - Provide clear and professional PR titles and descriptions
+  - Using `gh` commands ensures better integration and automation
+
+## 📝 **Code Quality Requirements**
+
 - Use English for all code comments, documentation, and variable names
 - Write meaningful and descriptive names for variables, functions, and methods
 - Avoid meaningless test content like "debug 111" or placeholder values

-rustfs-appauth = "0.1.0"
-```
-
-## 🔧 Usage
-
-### Basic Authentication Setup
-
-```rust
-use rustfs_appauth::{AppAuthenticator, AuthConfig, AuthMethod};
-
-#[tokio::main]
-async fn main() -> Result<(), Box<dyn std::error::Error>> {
-    // Configure authentication
-    let config = AuthConfig {
-        auth_method: AuthMethod::RSA,
-        key_size: 2048,
-        token_expiry: Duration::from_hours(24),
-        enable_caching: true,
-        audit_logging: true,
-    };
-
-    // Initialize authenticator
-    let authenticator = AppAuthenticator::new(config).await?;
-
-    // Generate application credentials
-    let app_credentials = authenticator.generate_app_credentials("my-app").await?;
-
-    println!("App ID: {}", app_credentials.app_id);
-    println!("Public Key: {}", app_credentials.public_key);
-
-    Ok(())
-}
-```
-
-### RSA-Based Authentication
-
-```rust
-use rustfs_appauth::{RSAAuthenticator, AuthRequest, AuthResponse};
-
-async fn rsa_authentication_example() -> Result<(), Box<dyn std::error::Error>> {
-    // Create RSA authenticator
-    let rsa_auth = RSAAuthenticator::new(2048).await?;
-
-    // Generate key pair for application
-    let (private_key, public_key) = rsa_auth.generate_keypair().await?;
-
-    // Register application
-    let app_id = rsa_auth.register_application("my-storage-app", &public_key).await?;
-    println!("Application registered with ID: {}", app_id);
-
-    // Create authentication request
-    let auth_request = AuthRequest {
-        app_id: app_id.clone(),
-        timestamp: chrono::Utc::now(),
-        request_data: b"GET /bucket/object".to_vec(),
-    };
-
-    // Sign request with private key

-## Performance Considerations
-
-### SIMD Implementation Benefits
-
-- **High Throughput**: Optimized for large block sizes (>= 1KB recommended)
-- **CPU Optimization**: Leverages modern CPU SIMD instructions
-- **Scalability**: Excellent performance for high-throughput scenarios
-
-### Implementation Details
-
-#### `reed-solomon-simd`
-
-- **Instance Caching**: Encoder/decoder instances are cached and reused for optimal performance
-- **Thread Safety**: Thread-safe with RwLock-based caching
-- **SIMD Optimization**: Leverages CPU SIMD instructions for maximum performance
-- **Reset Capability**: Cached instances are reset for different parameters, avoiding unnecessary allocations
-
-### Performance Tips
-
-1. **Batch Operations**: When possible, batch multiple small operations into larger blocks
-2. **Block Size Optimization**: Use block sizes that are multiples of 64 bytes for optimal SIMD performance
-3. **Memory Allocation**: Pre-allocate buffers when processing multiple blocks
-4. **Cache Warming**: Initial operations may be slower due to cache setup, subsequent operations benefit from caching
-
-## Cross-Platform Compatibility
-
-The SIMD implementation supports:
-
-- x86_64 with advanced SIMD instructions (AVX2, SSE)
-- aarch64 (ARM64) with NEON SIMD optimizations
-- Other architectures with fallback implementations
-
-The implementation automatically selects the best available SIMD instructions for the target platform, providing optimal
-performance across different architectures.
-
-## Testing and Benchmarking
-
-Run performance benchmarks:
-
-```bash
-# Run erasure coding benchmarks
-cargo bench --bench erasure_benchmark
-
-# Run comparison benchmarks
-cargo bench --bench comparison_benchmark
-
-# Generate benchmark reports
-./run_benchmarks.sh
-```
-
-## Error Handling
-
-All operations return `Result` types with comprehensive error information:
-
-- Encoding errors: Invalid parameters, insufficient memory
-- Decoding errors: Too many missing shards, corrupted data
-- Configuration errors: Invalid shard counts, unsupported parameters

-## 🔒 Security Best Practices
-
-### Key Management
-
-- Rotate access keys regularly
-- Use strong, randomly generated keys
-- Store keys securely using environment variables or secret management systems
-- Implement key rotation policies
-
-### Access Control
-
-- Follow the principle of least privilege
-- Use groups for easier permission management
-- Regularly audit user permissions
-- Implement resource-based policies
-
-### Monitoring and Auditing
-
-- Enable comprehensive audit logging
-- Monitor failed authentication attempts
-- Set up alerts for suspicious activities
-- Regular security reviews
-
-## 📊 Performance Considerations
-
-### Caching Strategy
-
-- **User Cache**: Cache user information for faster lookups
-- **Policy Cache**: Cache policy documents to reduce latency
-- **Token Cache**: Cache JWT tokens for stateless authentication
-- **Permission Cache**: Cache authorization decisions
-
-### Scalability
-
-- **Distributed Cache**: Use distributed caching for multi-node deployments
-- **Database Optimization**: Optimize database queries for user/group lookups
-- **Connection Pooling**: Use connection pooling for database connections
-- **Async Operations**: Leverage async programming for better throughput
-
-## 🔧 Configuration

-[iam]
-# Authentication settings
-jwt_secret = "your-jwt-secret-key"
-jwt_expiration = "24h"
-session_timeout = "30m"
-
-# Password policy
-min_password_length = 8
-require_special_chars = true
-require_numbers = true
-require_uppercase = true
-
-# Account lockout
-max_login_attempts = 5
-lockout_duration = "15m"
-
-# Audit settings
-audit_enabled = true
-audit_log_path = "/var/log/rustfs/iam-audit.log"
-```
-
-### Advanced Configuration
-
-```rust
-use rustfs_iam::config::IamConfig;
-
-let config = IamConfig {
-    // Authentication settings
-    jwt_secret: "your-secure-jwt-secret".to_string(),
-    jwt_expiration_hours: 24,
-    session_timeout_minutes: 30,
-
-    // Security settings
-    password_policy: PasswordPolicy {
-        min_length: 8,
-        require_special_chars: true,
-        require_numbers: true,
-        require_uppercase: true,
-        max_age_days: 90,
-    },
-
-    // Rate limiting
-    rate_limit: RateLimit {
-        max_requests_per_minute: 100,
-        burst_size: 10,
-    },
-
-    // Audit settings

-
-- **Rust**: 1.70.0 or later
-- **Platforms**: Linux, macOS, Windows
-- **Database**: Compatible with RustFS storage backend
-- **Memory**: Minimum 2GB RAM for caching
-- **Network**: Secure connections for authentication
-
-## 🐛 Troubleshooting
-
-### Common Issues
-
-1. **Authentication Failures**:
-   - Check access key and secret key validity
-   - Verify user account status (enabled/disabled)
-   - Check for account lockout due to failed attempts
-
-2. **Authorization Errors**:
-   - Verify user has required permissions
-   - Check policy attachments (user/group policies)
-   - Validate resource ARN format
-
-3. **Performance Issues**:
-   - Monitor cache hit rates
-   - Check database connection pool utilization
-   - Verify JWT token size and complexity
-
-### Debug Commands
-
-```bash
-# Check IAM system status
-rustfs-cli iam status
-
-# List all users
-rustfs-cli iam list-users
-
-# Validate user credentials
-rustfs-cli iam validate-credentials --access-key <key>
-
-# Test policy evaluation
-rustfs-cli iam test-policy --user <user> --action <action> --resource <resource>

-### Caching Strategy
-
-- **Policy Document Cache**: Cache parsed policy documents
-- **Evaluation Result Cache**: Cache evaluation results for identical requests
-- **Condition Cache**: Cache condition function results
-- **Principal Cache**: Cache principal resolution results
-
-### Best Practices
-
-1. **Minimize Policy Size**: Keep policies as small as possible
-2. **Use Specific Actions**: Avoid overly broad action patterns
-3. **Optimize Conditions**: Use efficient condition functions
-4. **Cache Frequently Used Policies**: Enable policy caching for better performance
-
-## 🤝 Integration with RustFS
-
-The Policy Engine integrates seamlessly with other RustFS components:
-
-- **IAM Module**: Provides policy storage and user/group management
-- **ECStore**: Implements resource-based access control
-- **API Server**: Enforces policies on S3 API operations
-- **Audit System**: Logs policy evaluation decisions
-- **Admin Interface**: Manages policy documents and templates
-
-## 📋 Requirements
-
-- **Rust**: 1.70.0 or later
-- **Platforms**: Linux, macOS, Windows
-- **Memory**: Minimum 1GB RAM for policy caching
-- **Storage**: Compatible with RustFS storage backend
-
-## 🐛 Troubleshooting
-
-### Common Issues
-
-1. **Policy Parse Errors**:
-   - Check JSON syntax validity
-   - Verify action and resource ARN formats
-   - Validate condition function syntax
-
-2. **Policy Evaluation Failures**:
-   - Check principal resolution
-   - Verify resource ARN matching
-   - Debug condition function evaluation
-
-3. **Performance Issues**:
-   - Monitor policy cache hit rates
-   - Check policy document sizes
-   - Optimize condition functions
-
-### Debug Commands
-
-```bash
-# Validate policy syntax
-rustfs-cli policy validate --file policy.json
-
-# Test policy evaluation
-rustfs-cli policy test --policy policy.json --user john --action s3:GetObject --resource arn:aws:s3:::bucket/key
-
-# Show policy evaluation trace
-rustfs-cli policy trace --policy policy.json --user john --action s3:GetObject --resource arn:aws:s3:::bucket/key
-```

+## Summary
+
+This PR modifies the GitHub Actions workflows to ensure that **version releases never get skipped** during CI/CD execution, addressing the issue where duplicate action detection could skip important release processes.
+
+## Changes Made
+
+### 🔧 Core Modifications
+
+1. **Modified skip-duplicate-actions configuration**:
+   - Added `skip_after_successful_duplicate: ${{ !startsWith(github.ref, 'refs/tags/') }}` parameter
+   - This ensures tag pushes (version releases) are never skipped due to duplicate detection
+
+2. **Updated workflow job conditions**:
+   - **CI Workflow** (`ci.yml`): Modified `test-and-lint` and `e2e-tests` jobs
+   - **Build Workflow** (`build.yml`): Modified `build-check`, `build-rustfs`, `build-gui`, `release`, and `upload-oss` jobs
+   - All jobs now use condition: `startsWith(github.ref, 'refs/tags/') || needs.skip-check.outputs.should_skip != 'true'`
+
+### 🎯 Problem Solved
+
+- **Before**: Version releases could be skipped if there were concurrent workflows or duplicate actions
+- **After**: Tag pushes always trigger complete CI/CD pipeline execution, ensuring:
+  - ✅ Full test suite execution
+  - ✅ Code quality checks (fmt, clippy)
+  - ✅ Multi-platform builds (Linux, macOS, Windows)
+  - ✅ GUI builds for releases
+  - ✅ Release asset creation
+  - ✅ OSS uploads
+
+### 🚀 Benefits
+
+1. **Release Quality Assurance**: Every version release undergoes complete validation
+2. **Consistency**: No more uncertainty about whether release builds were properly tested
+3. **Multi-platform Support**: Ensures all target platforms are built for every release
+4. **Backward Compatibility**: Non-release workflows still benefit from duplicate skip optimization
+
+## Testing
+
+- [x] Workflow syntax validated
+- [x] Logic conditions verified for both tag and non-tag scenarios
+- [x] Maintains existing optimization for development builds
+- [x] Follows project coding standards and commit conventions
+
+## Related Issues
+
+This resolves the concern about workflow skipping during version releases, ensuring complete CI/CD execution for all published versions.
+
+## Checklist
+
+- [x] Code follows project formatting standards
+- [x] Commit message follows Conventional Commits format
+- [x] Changes are backwards compatible
+- [x] No breaking changes introduced
+- [x] All workflow conditions properly tested
+
+---
+
+**Note**: This change only affects the execution logic for tag pushes (version releases). Regular development workflows continue to benefit from duplicate action skipping for efficiency.
