-## Project Overview
-
-RustFS is a high-performance distributed object storage system written in Rust, compatible with S3 API. The project adopts a modular architecture, supporting erasure coding storage, multi-tenant management, observability, and other enterprise-level features.
-
-## Core Architecture Principles
-
-### 1. Modular Design
-
-- Project uses Cargo workspace structure, containing multiple independent crates
-- Core modules: `rustfs` (main service), `ecstore` (erasure coding storage), `common` (shared components)
-- Functional modules: `iam` (identity management), `madmin` (management interface), `crypto` (encryption), etc.
-- Tool modules: `cli` (command line tool), `crates/*` (utility libraries)
-
-### 2. Asynchronous Programming Pattern
-
-- Comprehensive use of `tokio` async runtime
-- Prioritize `async/await` syntax
-- Use `async-trait` for async methods in traits
-- Avoid blocking operations, use `spawn_blocking` when necessary
-
-### 3. Error Handling Strategy
-
-- **Use modular, type-safe error handling with `thiserror`**
-- Each module should define its own error type using `thiserror::Error` derive macro
-- Support error chains and context information through `#[from]` and `#[source]` attributes
-- Use `Result<T>` type aliases for consistency within each module
-- Error conversion between modules should use explicit `From` implementations
-- Follow the pattern: `pub type Result<T> = core::result::Result<T, Error>`
-- Use `#[error("description")]` attributes for clear error messages
-- Support error downcasting when needed through `other()` helper methods
-- Implement `Clone` for errors when required by the domain logic
-- **Current module error types:**
-  - `ecstore::error::StorageError` - Storage layer errors
-  - `ecstore::disk::error::DiskError` - Disk operation errors
-  - `iam::error::Error` - Identity and access management errors
-  - `policy::error::Error` - Policy-related errors
-  - `crypto::error::Error` - Cryptographic operation errors
-  - `filemeta::error::Error` - File metadata errors
-  - `rustfs::error::ApiError` - API layer errors
-  - Module-specific error types for specialized functionality
-
-## Code Style Guidelines
-
-### 1. Formatting Configuration
-
-```toml
-max_width = 130
-fn_call_width = 90
-single_line_let_else_max_width = 100
-```
-
-### 2. **🔧 MANDATORY Code Formatting Rules**
-
-**CRITICAL**: All code must be properly formatted before committing. This project enforces strict formatting standards to maintain code consistency and readability.
-
-#### Pre-commit Requirements (MANDATORY)
-
-Before every commit, you **MUST**:
-
-1. **Format your code**:
-
-   ```bash
-   cargo fmt --all
-   ```
-
-2. **Verify formatting**:
-
-   ```bash
-   cargo fmt --all --check
-   ```
-
-3. **Pass clippy checks**:
-
-   ```bash
-   cargo clippy --all-targets --all-features -- -D warnings
-   ```
-
-4. **Ensure compilation**:
-
-   ```bash
-   cargo check --all-targets
-   ```
-
-#### Quick Commands
-
-Use these convenient Makefile targets for common tasks:
-
-```bash
-# Format all code
-make fmt
-
-# Check if code is properly formatted
-make fmt-check
-
-# Run clippy checks
-make clippy
-
-# Run compilation check
-make check
-
-# Run tests
-make test
-
-# Run all pre-commit checks (format + clippy + check + test)
-make pre-commit
-
-# Setup git hooks (one-time setup)
-make setup-hooks
-```
-
-#### 🔒 Automated Pre-commit Hooks
-
-This project includes a pre-commit hook that automatically runs before each commit to ensure:
-
-- ✅ Code is properly formatted (`cargo fmt --all --check`)
-- ✅ No clippy warnings (`cargo clippy --all-targets --all-features -- -D warnings`)
-- ✅ Code compiles successfully (`cargo check --all-targets`)
-
-**Setting Up Pre-commit Hooks** (MANDATORY for all developers):
-
-Run this command once after cloning the repository:
-
-```bash
-make setup-hooks
-```
-
-Or manually:
-
-```bash
-chmod +x .git/hooks/pre-commit
-```
-
-#### 🚫 Commit Prevention
-
-If your code doesn't meet the formatting requirements, the pre-commit hook will:
-
-1. **Block the commit** and show clear error messages
-2. **Provide exact commands** to fix the issues
-3. **Guide you through** the resolution process
-
-Example output when formatting fails:
-
-```
-❌ Code formatting check failed!
-💡 Please run 'cargo fmt --all' to format your code before committing.
-
-🔧 Quick fix:
-   cargo fmt --all
-   git add .
-   git commit
-```
-
-### 3. Naming Conventions
-
-- Use `snake_case` for functions, variables, modules
-- Use `PascalCase` for types, traits, enums
-- Constants use `SCREAMING_SNAKE_CASE`
-- Global variables prefix `GLOBAL_`, e.g., `GLOBAL_Endpoints`
-- Use meaningful and descriptive names for variables, functions, and methods
-- Avoid meaningless names like `temp`, `data`, `foo`, `bar`, `test123`
-- Choose names that clearly express the purpose and intent
-
-### 4. Type Declaration Guidelines
-
-- **Prefer type inference over explicit type declarations** when the type is obvious from context
-- Let the Rust compiler infer types whenever possible to reduce verbosity and improve maintainability
-- Only specify types explicitly when:
-  - The type cannot be inferred by the compiler
-  - Explicit typing improves code clarity and readability
-  - Required for API boundaries (function signatures, public struct fields)
-  - Needed to resolve ambiguity between multiple possible types
-
-**Good examples (prefer these):**
-
-```rust
-// Compiler can infer the type
-let items = vec![1, 2, 3, 4];
-let config = Config::default();
-let result = process_data(&input);
-
-// Iterator chains with clear context
-let filtered: Vec<_> = items.iter().filter(|&&x| x > 2).collect();
-```
-
-**Avoid unnecessary explicit types:**
-
-```rust
-// Unnecessary - type is obvious
-let items: Vec<i32> = vec![1, 2, 3, 4];
-let config: Config = Config::default();
-let result: ProcessResult = process_data(&input);
-```
-
-**When explicit types are beneficial:**
-
-```rust
-// API boundaries - always specify types
-pub fn process_data(input: &[u8]) -> Result<ProcessResult, Error> { ... }
-
-// Ambiguous cases - explicit type needed
-let value: f64 = "3.14".parse().unwrap();
-
-// Complex generic types - explicit for clarity
-let cache: HashMap<String, Arc<Mutex<CacheEntry>>> = HashMap::new();
-```
-
-### 5. Documentation Comments
-
-- Public APIs must have documentation comments
-- Use `///` for documentation comments
-- Complex functions add `# Examples` and `# Parameters` descriptions
-- Error cases use `# Errors` descriptions
-- Always use English for all comments and documentation
-- Avoid meaningless comments like "debug 111" or placeholder text
-
-### 6. Import Guidelines
-
-- Standard library imports first
-- Third-party crate imports in the middle
-- Project internal imports last
-- Group `use` statements with blank lines between groups
-
-## Asynchronous Programming Guidelines
-
-### 1. Trait Definition
-
-```rust
-#[async_trait::async_trait]
-pub trait StorageAPI: Send + Sync {
-    async fn get_object(&self, bucket: &str, object: &str) -> Result<ObjectInfo>;
-}
-```
-
-### 2. Error Handling
-
-```rust
-// Use ? operator to propagate errors
-async fn example_function() -> Result<()> {
-    let data = read_file("path").await?;
-    process_data(data).await?;
-    Ok(())
-}
-```
-
-### 3. Concurrency Control
-
-- Use `Arc` and `Mutex`/`RwLock` for shared state management
-- Prioritize async locks from `tokio::sync`
-- Avoid holding locks for long periods
-
-## Logging and Tracing Guidelines
-
-### 1. Tracing Usage
-
-```rust
-#[tracing::instrument(skip(self, data))]
-async fn process_data(&self, data: &[u8]) -> Result<()> {
-    info!("Processing {} bytes", data.len());
-    // Implementation logic
-}
-```
-
-### 2. Log Levels
-
-- `error!`: System errors requiring immediate attention
-- `warn!`: Warning information that may affect functionality
-- `info!`: Important business information
-- `debug!`: Debug information for development use
-- `trace!`: Detailed execution paths
-
-### 3. Structured Logging
-
-```rust
-info!(
-    counter.rustfs_api_requests_total = 1_u64,
-    key_request_method = %request.method(),
-    key_request_uri_path = %request.uri().path(),
-    "API request processed"
-);
-```
-
-## Error Handling Guidelines
-
-### 1. Error Type Definition
-
-```rust
-// Use thiserror for module-specific error types
-#[derive(thiserror::Error, Debug)]
-pub enum MyError {
-    #[error("IO error: {0}")]
-    Io(#[from] std::io::Error),
-
-    #[error("Storage error: {0}")]
-    Storage(#[from] ecstore::error::StorageError),
-
-    #[error("Custom error: {message}")]
-    Custom { message: String },
-
-    #[error("File not found: {path}")]
-    FileNotFound { path: String },
-
-    #[error("Invalid configuration: {0}")]
-    InvalidConfig(String),
-}
-
-// Provide Result type alias for the module
-pub type Result<T> = core::result::Result<T, MyError>;
-```
-
-### 2. Error Helper Methods
-
-```rust
-impl MyError {
-    /// Create error from any compatible error type
-    pub fn other<E>(error: E) -> Self
-    where
-        E: Into<Box<dyn std::error::Error + Send + Sync>>,
-    {
-        MyError::Io(std::io::Error::other(error))
-    }
-}
-```
-
-### 3. Error Conversion Between Modules
-
-```rust
-// Convert between different module error types
-impl From<ecstore::error::StorageError> for MyError {
-    fn from(e: ecstore::error::StorageError) -> Self {
-        match e {
-            ecstore::error::StorageError::FileNotFound => {
-                MyError::FileNotFound { path: "unknown".to_string() }
-            }
-            _ => MyError::Storage(e),
-        }
-    }
-}
-
-// Provide reverse conversion when needed
-impl From<MyError> for ecstore::error::StorageError {
-    fn from(e: MyError) -> Self {
-        match e {
-            MyError::FileNotFound { .. } => ecstore::error::StorageError::FileNotFound,
-            MyError::Storage(e) => e,
-            _ => ecstore::error::StorageError::other(e),
-        }
-    }
-}
-```
-
-### 4. Error Context and Propagation
-
-```rust
-// Use ? operator for clean error propagation
-async fn example_function() -> Result<()> {
-    let data = read_file("path").await?;
-    process_data(data).await?;
-    Ok(())
-}
-
-// Add context to errors
-fn process_with_context(path: &str) -> Result<()> {
-    std::fs::read(path)
-        .map_err(|e| MyError::Custom {
-            message: format!("Failed to read {}: {}", path, e)
-        })?;
-    Ok(())
-}
-```
-
-### 5. API Error Conversion (S3 Example)
-
-```rust
-// Convert storage errors to API-specific errors
-use s3s::{S3Error, S3ErrorCode};
-
-#[derive(Debug)]
-pub struct ApiError {
-    pub code: S3ErrorCode,
-    pub message: String,
-    pub source: Option<Box<dyn std::error::Error + Send + Sync>>,
-}
-
-impl From<ecstore::error::StorageError> for ApiError {
-    fn from(err: ecstore::error::StorageError) -> Self {
-        let code = match &err {
-            ecstore::error::StorageError::BucketNotFound(_) => S3ErrorCode::NoSuchBucket,
-            ecstore::error::StorageError::ObjectNotFound(_, _) => S3ErrorCode::NoSuchKey,
-            ecstore::error::StorageError::BucketExists(_) => S3ErrorCode::BucketAlreadyExists,
-            ecstore::error::StorageError::InvalidArgument(_, _, _) => S3ErrorCode::InvalidArgument,
-            ecstore::error::StorageError::MethodNotAllowed => S3ErrorCode::MethodNotAllowed,
-            ecstore::error::StorageError::StorageFull => S3ErrorCode::ServiceUnavailable,
-            _ => S3ErrorCode::InternalError,
-        };
-
-        ApiError {
-            code,
-            message: err.to_string(),
-            source: Some(Box::new(err)),
-        }
-    }
-}
-
-impl From<ApiError> for S3Error {
-    fn from(err: ApiError) -> Self {
-        let mut s3e = S3Error::with_message(err.code, err.message);
-        if let Some(source) = err.source {
-            s3e.set_source(source);
-        }
-        s3e
-    }
-}
-```
-
-### 6. Error Handling Best Practices
-
-#### Pattern Matching and Error Classification
-
-```rust
-// Use pattern matching for specific error handling
-async fn handle_storage_operation() -> Result<()> {
-    match storage.get_object("bucket", "key").await {
-        Ok(object) => process_object(object),
-        Err(ecstore::error::StorageError::ObjectNotFound(bucket, key)) => {
-            warn!("Object not found: {}/{}", bucket, key);
-            create_default_object(bucket, key).await
-        }
-        Err(ecstore::error::StorageError::BucketNotFound(bucket)) => {
-            error!("Bucket not found: {}", bucket);
-            Err(MyError::Custom {
-                message: format!("Bucket {} does not exist", bucket)
-            })
-        }
-        Err(e) => {
-            error!("Storage operation failed: {}", e);
-            Err(MyError::Storage(e))
-        }
-    }
-}
-```
-
-#### Error Aggregation and Reporting
-
-```rust
-// Collect and report multiple errors
-pub fn validate_configuration(config: &Config) -> Result<()> {
-    let mut errors = Vec::new();
-
-    if config.bucket_name.is_empty() {
-        errors.push("Bucket name cannot be empty");
-    }
-
-    if config.region.is_empty() {
-        errors.push("Region must be specified");
-    }
-
-    if !errors.is_empty() {
-        return Err(MyError::Custom {
-            message: format!("Configuration validation failed: {}", errors.join(", "))
-        });
-    }
-
-    Ok(())
-}
-```
-
-#### Contextual Error Information
-
-```rust
-// Add operation context to errors
-#[tracing::instrument(skip(self))]
-async fn upload_file(&self, bucket: &str, key: &str, data: Vec<u8>) -> Result<()> {
-    self.storage
-        .put_object(bucket, key, data)
-        .await
-        .map_err(|e| MyError::Custom {
-            message: format!("Failed to upload {}/{}: {}", bucket, key, e)
-        })
-}
-```
-
-## Performance Optimization Guidelines
-
-### 1. Memory Management
-
-- Use `Bytes` instead of `Vec<u8>` for zero-copy operations
-- Avoid unnecessary cloning, use reference passing
-- Use `Arc` for sharing large objects
-
-### 2. Concurrency Optimization
-
-```rust
-// Use join_all for concurrent operations
-let futures = disks.iter().map(|disk| disk.operation());
-let results = join_all(futures).await;
-```
-
-### 3. Caching Strategy
-
-- Use `LazyLock` for global caching
-- Implement LRU cache to avoid memory leaks
-
-## Testing Guidelines
-
-### 1. Unit Tests
-
-```rust
-#[cfg(test)]
-mod tests {
-    use super::*;
-    use test_case::test_case;
-
-    #[tokio::test]
-    async fn test_async_function() {
-        let result = async_function().await;
-        assert!(result.is_ok());
-    }
-
-    #[test_case("input1", "expected1")]
-    #[test_case("input2", "expected2")]
-    fn test_with_cases(input: &str, expected: &str) {
-        assert_eq!(function(input), expected);
-    }
-
-    #[test]
-    fn test_error_conversion() {
-        use ecstore::error::StorageError;
-
-        let storage_err = StorageError::BucketNotFound("test-bucket".to_string());
-        let api_err: ApiError = storage_err.into();
-
-        assert_eq!(api_err.code, S3ErrorCode::NoSuchBucket);
-        assert!(api_err.message.contains("test-bucket"));
-        assert!(api_err.source.is_some());
-    }
-
-    #[test]
-    fn test_error_types() {
-        let io_err = std::io::Error::new(std::io::ErrorKind::NotFound, "file not found");
-        let my_err = MyError::Io(io_err);
-
-        // Test error matching
-        match my_err {
-            MyError::Io(_) => {}, // Expected
-            _ => panic!("Unexpected error type"),
-        }
-    }
-
-    #[test]
-    fn test_error_context() {
-        let result = process_with_context("nonexistent_file.txt");
-        assert!(result.is_err());
-
-        let err = result.unwrap_err();
-        match err {
-            MyError::Custom { message } => {
-                assert!(message.contains("Failed to read"));
-                assert!(message.contains("nonexistent_file.txt"));
-            }
-            _ => panic!("Expected Custom error"),
-        }
-    }
-}
-```
-
-### 2. Integration Tests
-
-- Use `e2e_test` module for end-to-end testing
-- Simulate real storage environments
-
-### 3. Test Quality Standards
-
-- Write meaningful test cases that verify actual functionality
-- Avoid placeholder or debug content like "debug 111", "test test", etc.
-- Use descriptive test names that clearly indicate what is being tested
-- Each test should have a clear purpose and verify specific behavior
-- Test data should be realistic and representative of actual use cases
-
-## Cross-Platform Compatibility Guidelines
-
-### 1. CPU Architecture Compatibility
-
-- **Always consider multi-platform and different CPU architecture compatibility** when writing code
-- Support major architectures: x86_64, aarch64 (ARM64), and other target platforms
-- Use conditional compilation for architecture-specific code:
-
-```rust
-#[cfg(target_arch = "x86_64")]
-fn optimized_x86_64_function() { /* x86_64 specific implementation */ }
-
-#[cfg(target_arch = "aarch64")]
-fn optimized_aarch64_function() { /* ARM64 specific implementation */ }
-
-#[cfg(not(any(target_arch = "x86_64", target_arch = "aarch64")))]
-fn generic_function() { /* Generic fallback implementation */ }
-```
-
-### 2. Platform-Specific Dependencies
-
-- Use feature flags for platform-specific dependencies
-- Provide fallback implementations for unsupported platforms
-- Test on multiple architectures in CI/CD pipeline
-
-### 3. Endianness Considerations
-
-- Use explicit byte order conversion when dealing with binary data
-- Prefer `to_le_bytes()`, `from_le_bytes()` for consistent little-endian format
-- Use `byteorder` crate for complex binary format handling
-
-### 4. SIMD and Performance Optimizations
-
-- Use portable SIMD libraries like `wide` or `packed_simd`
-- Provide fallback implementations for non-SIMD architectures
-- Use runtime feature detection when appropriate
-
-## Security Guidelines
-
-### 1. Memory Safety
-
-- Disable `unsafe` code (workspace.lints.rust.unsafe_code = "deny")
-- Use `rustls` instead of `openssl`
-
-### 2. Authentication and Authorization
-
-```rust
-// Use IAM system for permission checks
-let identity = iam.authenticate(&access_key, &secret_key).await?;
-iam.authorize(&identity, &action, &resource).await?;
-```
-
-## Configuration Management Guidelines
-
-### 1. Environment Variables
-
-- Use `RUSTFS_` prefix
-- Support both configuration files and environment variables
-- Provide reasonable default values
-
-### 2. Configuration Structure
-
-```rust
-#[derive(Debug, Deserialize, Clone)]

-    pub address: String,
-    pub volumes: String,
-    #[serde(default)]
-    pub console_enable: bool,

-
-## Dependency Management Guidelines
-
-### 1. Workspace Dependencies
-
-- Manage versions uniformly at workspace level
-- Use `workspace = true` to inherit configuration
-
-### 2. Feature Flags
-
-```rust
-[features]
-default = ["file"]
-gpu = ["dep:nvml-wrapper"]
-kafka = ["dep:rdkafka"]
-```
-
-## Deployment and Operations Guidelines
-
-### 1. Containerization
-
-- Provide Dockerfile and docker-compose configuration
-- Support multi-stage builds to optimize image size
-
-### 2. Observability
-
-- Integrate OpenTelemetry for distributed tracing
-- Support Prometheus metrics collection
-- Provide Grafana dashboards
-
-### 3. Health Checks
-
-```rust
-// Implement health check endpoint
-async fn health_check() -> Result<HealthStatus> {
-    // Check component status
-}
-```
-

-
-## Common Patterns and Best Practices
-
-### 1. Resource Management
-
-```rust
-// Use RAII pattern for resource management
-pub struct ResourceGuard {
-    resource: Resource,
-}
-
-impl Drop for ResourceGuard {
-    fn drop(&mut self) {
-        // Clean up resources
-    }
-}
-```
-
-### 2. Dependency Injection
-
-```rust
-// Use dependency injection pattern
-pub struct Service {
-    config: Arc<Config>,
-    storage: Arc<dyn StorageAPI>,
-}
-```
-
-### 3. Graceful Shutdown
-
-```rust
-// Implement graceful shutdown
-async fn shutdown_gracefully(shutdown_rx: &mut Receiver<()>) {
-    tokio::select! {
-        _ = shutdown_rx.recv() => {
-            info!("Received shutdown signal");
-            // Perform cleanup operations
-        }
-        _ = tokio::time::sleep(SHUTDOWN_TIMEOUT) => {
-            warn!("Shutdown timeout reached");
-        }
-    }
-}
-```
-
-## Domain-Specific Guidelines
-
-### 1. Storage Operations
-
-- All storage operations must support erasure coding
-- Implement read/write quorum mechanisms
-- Support data integrity verification
-
-### 2. Network Communication
-
-- Use gRPC for internal service communication
-- HTTP/HTTPS support for S3-compatible API
-- Implement connection pooling and retry mechanisms
-
-### 3. Metadata Management
-
-- Use FlatBuffers for serialization
-- Support version control and migration
-- Implement metadata caching
-
-These rules should serve as guiding principles when developing the RustFS project, ensuring code quality, performance, and maintainability.
-
-### 4. Code Operations
-
-#### Branch Management
-
-- **🚨 CRITICAL: NEVER modify code directly on main or master branch - THIS IS ABSOLUTELY FORBIDDEN 🚨**
-- **⚠️ ANY DIRECT COMMITS TO MASTER/MAIN WILL BE REJECTED AND MUST BE REVERTED IMMEDIATELY ⚠️**
-- **🔒 ALL CHANGES MUST GO THROUGH PULL REQUESTS - NO DIRECT COMMITS TO MAIN UNDER ANY CIRCUMSTANCES 🔒**
-- **Always work on feature branches - NO EXCEPTIONS**
-- Always check the .cursorrules file before starting to ensure you understand the project guidelines
-- **MANDATORY workflow for ALL changes:**
-   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)
-   4. Make your changes ONLY on the feature branch
-   5. Test thoroughly before committing
-   6. Commit and push to the 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**
-- **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
-- Before each change, carefully read the existing code to ensure you understand the code structure and implementation, do not break existing logic implementation, do not introduce new issues
-- Ensure each change provides sufficient test cases to guarantee code correctness
-- Do not arbitrarily modify numbers and constants in test cases, carefully analyze their meaning to ensure test case correctness
-- When writing or modifying tests, check existing test cases to ensure they have scientific naming and rigorous logic testing, if not compliant, modify test cases to ensure scientific and rigorous testing
-- **Before committing any changes, run `cargo clippy --all-targets --all-features -- -D warnings` to ensure all code passes Clippy checks**
-- After each development completion, first git add . then git commit -m "feat: feature description" or "fix: issue description", ensure compliance with [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
-- **Keep commit messages concise and under 72 characters** for the title line, use body for detailed explanations if needed
-- After each development completion, first git push to remote repository
-- After each change completion, summarize the changes, do not create summary files, provide a brief change description, ensure compliance with [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
-- Provide change descriptions needed for PR in the conversation, ensure compliance with [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
-- **Always provide PR descriptions in English** after completing any changes, including:
-  - Clear and concise title following Conventional Commits format
-  - Detailed description of what was changed and why
-  - List of key changes and improvements
-  - Any breaking changes or migration notes if applicable
-  - Testing information and verification steps
-- **Provide PR descriptions in copyable markdown format** enclosed in code blocks for easy one-click copying
-
-## 🚫 AI 文档生成限制
-
-### 禁止生成总结文档
-
-- **严格禁止创建任何形式的AI生成总结文档**
-- **不得创建包含大量表情符号、详细格式化表格和典型AI风格的文档**
-- **不得在项目中生成以下类型的文档：**
-  - 基准测试总结文档（BENCHMARK*.md）
-  - 实现对比分析文档（IMPLEMENTATION_COMPARISON*.md）
-  - 性能分析报告文档
-  - 架构总结文档
-  - 功能对比文档
-  - 任何带有大量表情符号和格式化内容的文档
-- **如果需要文档，请只在用户明确要求时创建，并保持简洁实用的风格**
-- **文档应当专注于实际需要的信息，避免过度格式化和装饰性内容**
-- **任何发现的AI生成总结文档都应该立即删除**
-
-### 允许的文档类型
-
-- README.md（项目介绍，保持简洁）
-- 技术文档（仅在明确需要时创建）
-- 用户手册（仅在明确需要时创建）
-- API文档（从代码生成）
-- 变更日志（CHANGELOG.md）

+# Repository Guidelines
+
+## Communication Rules
+- Respond to the user in Chinese; use English in all other contexts.
+
+## Project Structure & Module Organization
+The workspace root hosts shared dependencies in `Cargo.toml`. The service binary lives under `rustfs/src/main.rs`, while reusable crates sit in `crates/` (`crypto`, `iam`, `kms`, and `e2e_test`). Local fixtures for standalone flows reside in `test_standalone/`, deployment manifests are under `deploy/`, Docker assets sit at the root, and automation lives in `scripts/`. Skim each crate’s README or module docs before contributing changes.
+
+## Build, Test, and Development Commands
+Run `cargo check --all-targets` for fast validation. Build release binaries via `cargo build --release` or the pipeline-aligned `make build`. Use `./build-rustfs.sh --dev` for iterative development and `./build-rustfs.sh --platform <target>` for cross-compiles. Prefer `make pre-commit` before pushing to cover formatting, clippy, checks, and tests.
+Always ensure `cargo fmt --all --check`, `cargo test --workspace --exclude e2e_test`, and `cargo clippy --all-targets --all-features -- -D warnings` complete successfully after each code change to keep the tree healthy and warning-free.
+
+## Coding Style & Naming Conventions
+Formatting follows the repo `rustfmt.toml` (130-column width). Use `snake_case` for items, `PascalCase` for types, and `SCREAMING_SNAKE_CASE` for constants. Avoid `unwrap()` or `expect()` outside tests; bubble errors with `Result` and crate-specific `thiserror` types. Keep async code non-blocking and offload CPU-heavy work with `tokio::task::spawn_blocking` when necessary.
+
+## Testing Guidelines
+Co-locate unit tests with their modules and give behavior-led names such as `handles_expired_token`. Integration suites belong in each crate’s `tests/` directory, while exhaustive end-to-end scenarios live in `crates/e2e_test/`. Run `cargo test --workspace --exclude e2e_test` during iteration, `cargo nextest run --all --exclude e2e_test` when available, and finish with `cargo test --all` before requesting review. Use `NO_PROXY=127.0.0.1,localhost HTTP_PROXY= HTTPS_PROXY=` for KMS e2e tests.
+When fixing bugs or adding features, include regression tests that capture the new behavior so future changes cannot silently break it.
+
+## Commit & Pull Request Guidelines
+Work on feature branches (e.g., `feat/...`) after syncing `main`. Follow Conventional Commits under 72 characters (e.g., `feat: add kms key rotation`). Each commit must compile, format cleanly, and pass `make pre-commit`. Open PRs with a concise summary, note verification commands, link relevant issues, and wait for reviewer approval.
+
+## Security & Configuration Tips
+Do not commit secrets or cloud credentials; prefer environment variables or vault tooling. Review IAM- and KMS-related changes with a second maintainer. Confirm proxy settings before running sensitive tests to avoid leaking traffic outside localhost.

+
+## KMS (Key Management Service) Architecture
+
+### KMS Implementation Status
+
+- **Full KMS Integration:** Complete implementation with Local and Vault backends
+- **Automatic Configuration:** KMS auto-configures on startup with `--kms-enable` flag
+- **Encryption Support:** Full S3-compatible server-side encryption (SSE-S3, SSE-KMS, SSE-C)
+- **Admin API:** Complete KMS management via HTTP admin endpoints
+- **Production Ready:** Comprehensive testing including large files and key isolation
+
+### KMS Configuration
+
+- **Local Backend:** `--kms-backend local --kms-key-dir <path> --kms-default-key-id <id>`
+- **Vault Backend:** `--kms-backend vault --kms-vault-endpoint <url> --kms-vault-key-name <name>`
+- **Auto-startup:** KMS automatically initializes when `--kms-enable` is provided
+- **Manual Configuration:** Also supports dynamic configuration via admin API
+
+### S3 Encryption Support
+
+- **SSE-S3:** Server-side encryption with S3-managed keys (`ServerSideEncryption: AES256`)
+- **SSE-KMS:** Server-side encryption with KMS-managed keys (`ServerSideEncryption: aws:kms`)
+- **SSE-C:** Server-side encryption with customer-provided keys
+- **Response Headers:** All encryption types return correct `server_side_encryption` headers in PUT/GET responses
+
+### KMS Testing Architecture
+
+- **Comprehensive E2E Tests:** Located in `crates/e2e_test/src/kms/`
+- **Test Environments:** Automated test environment setup with temporary directories
+- **Encryption Coverage:** Tests all three encryption types (SSE-S3, SSE-KMS, SSE-C)
+- **API Coverage:** Tests all KMS admin APIs (CreateKey, DescribeKey, ListKeys, etc.)
+- **Edge Cases:** Key isolation, large file handling, error scenarios
+
+### Key Files for KMS
+
+- `crates/kms/` - Core KMS implementation with Local/Vault backends
+- `rustfs/src/main.rs` - KMS auto-initialization in `init_kms_system()`
+- `rustfs/src/storage/ecfs.rs` - SSE encryption/decryption in PUT/GET operations
+- `rustfs/src/admin/handlers/kms*.rs` - KMS admin endpoints
+- `crates/e2e_test/src/kms/` - Comprehensive KMS test suite
+- `crates/rio/src/encrypt_reader.rs` - Streaming encryption for large files
+
+## Code Style and Safety Requirements
+
+- **Language Requirements:**
+    - Communicate with me in Chinese, but **only English can be used in code files**
+    - Code comments, function names, variable names, and all text in source files must be in English only
+    - No Chinese characters, emojis, or non-ASCII characters are allowed in any source code files
+    - This includes comments, strings, documentation, and any other text within code files
+- **Safety-Critical Rules:**
+    - `unsafe_code = "deny"` enforced at workspace level
+    - Never use `unwrap()`, `expect()`, or panic-inducing code except in tests
+    - Avoid blocking I/O operations in async contexts
+    - Use proper error handling with `Result<T, E>` and `Option<T>`
+    - Follow Rust's ownership and borrowing rules strictly
+- **Performance Guidelines:**
+    - Use `cargo clippy --all-targets --all-features -- -D warnings` to catch issues
+    - Prefer `anyhow` for error handling in applications, `thiserror` for libraries
+    - Use appropriate async runtimes and avoid blocking calls
+- **Testing Standards:**
+    - All new features must include comprehensive tests
+    - Use `#[cfg(test)]` for test-only code that may use panic macros
+    - E2E tests should cover KMS integration scenarios
+
+## Common Development Tasks
+
+### Running KMS Tests Locally
+
+1. **Clear proxy settings:** KMS tests require direct localhost connections
+2. **Use serial execution:** `--test-threads=1` prevents port conflicts
+3. **Enable output:** `--nocapture` shows detailed test logs
+4. **Full command:**
+   `NO_PROXY=127.0.0.1,localhost HTTP_PROXY= HTTPS_PROXY= http_proxy= https_proxy= cargo test --package e2e_test test_local_kms_end_to_end -- --nocapture --test-threads=1`
+
+### KMS Development Workflow
+
+1. **Code changes:** Modify KMS-related code in `crates/kms/` or `rustfs/src/`
+2. **Compile:** Always run `cargo build` after changes
+3. **Test specific functionality:** Use targeted test commands for faster iteration
+4. **Full validation:** Run complete end-to-end tests before commits
+
+### Debugging KMS Issues
+
+- **Server startup:** Check that KMS auto-initializes with debug logs
+- **Encryption failures:** Verify SSE headers are correctly set in both PUT and GET responses
+- **Test failures:** Use `--nocapture` to see detailed error messages
+- **Key management:** Test admin API endpoints with proper authentication
+
+## Important Reminders
+
+- **Always compile after code changes:** Use `cargo build` to catch errors early
+- **Don't bypass tests:** All functionality must be properly tested, not worked around
+- **Use proper error handling:** Never use `unwrap()` or `expect()` in production code (except tests)
+- **Follow S3 compatibility:** Ensure all encryption types return correct HTTP response headers
+
+# important-instruction-reminders
+
+Do what has been asked; nothing more, nothing less.
+NEVER create files unless they're absolutely necessary for achieving your goal.
+ALWAYS prefer editing an existing file to creating a new one.
+NEVER proactively create documentation files (*.md) or README files. Only create documentation files if explicitly
+requested by the User.

 ### RustFS vs Other object storage
 
-| RustFS | Other object storage|
-| - | - |
-| Powerful Console | Simple and useless Console |
-| Developed based on Rust language, memory is safer | Developed in Go or C, with potential issues like memory GC/leaks |
-| Does not report logs to third-party countries  | Reporting logs to other third countries may violate national security laws |
-| Licensed under Apache, more business-friendly  | AGPL V3 License and other License, polluted open source and License traps, infringement of intellectual property rights |
-| Comprehensive S3 support, works with domestic and international cloud providers  | Full support for S3, but no local cloud vendor support |
-| Rust-based development, strong support for secure and innovative devices  | Poor support for edge gateways and secure innovative devices|
-| Stable commercial prices, free community support | High pricing, with costs up to $250,000 for 1PiB |
-| No risk | Intellectual property risks and risks of prohibited uses |

-4. **创建存储桶**：使用控制台为您的对象创建新的存储桶。
-5. **上传对象**：您可以直接通过控制台上传文件，或使用 S3 兼容的 API 与您的 RustFS 实例交互。
+对于使用 Docker 安装来讲，你还可以使用 `docker compose` 来启动 rustfs 实例。在仓库的根目录下面有一个 `docker-compose.yml`
+文件。运行如下命令即可：
+
+  ```
+  docker compose --profile observability up -d
+  ```
+
+**注意**：在使用 `docker compose` 之前，你应该仔细阅读一下 `docker-compose.yaml`，因为该文件中包含多个服务，除了 rustfs
+以外，还有 grafana、prometheus、jaeger 等，这些是为 rustfs 可观测性服务的，还有 redis 和 nginx。你想启动哪些容器，就需要用
+`--profile` 参数指定相应的 profile。
+
+3. **从源码构建（方案三）- 高级用户**
+
+   面向希望从源码构建支持多架构 Docker 镜像的开发者：
+
+   ```bash
+   # 本地构建多架构镜像
+   ./docker-buildx.sh --build-arg RELEASE=latest
+
+   # 构建并推送至镜像仓库
+   ./docker-buildx.sh --push
+
+   # 构建指定版本
+   ./docker-buildx.sh --release v1.0.0 --push
+
+   # 构建并推送到自定义镜像仓库
+   ./docker-buildx.sh --registry your-registry.com --namespace yourname --push
+   ```
+
+   `docker-buildx.sh` 脚本支持：
+    - **多架构构建**：`linux/amd64`、`linux/arm64`
+    - **自动版本检测**：可使用 git 标签或提交哈希
+    - **仓库灵活性**：支持 Docker Hub、GitHub Container Registry 等
+    - **构建优化**：包含缓存和并行构建
+
+   你也可以使用 Makefile 提供的目标命令以提升便捷性：
+
+   ```bash
+   make docker-buildx                    # 本地构建
+   make docker-buildx-push               # 构建并推送
+   make docker-buildx-version VERSION=v1.0.0  # 构建指定版本
+   make help-docker                      # 显示全部 Docker 相关命令
+   ```
+
+4. **使用 Helm Chart 部署（方案四）- 云原生环境**
+
+   按照 [helm chart 说明文档](./helm/README.md) 的指引，在 Kubernetes 集群中安装 RustFS。
+
+5. **访问控制台**：打开 Web 浏览器并导航到 `http://localhost:9000` 以访问 RustFS 控制台，默认的用户名和密码是

+
+**Audit Target Management System for RustFS**
+
+`rustfs-audit` is a comprehensive audit logging system designed for RustFS. It provides multi-target fan-out, hot reload
+capabilities, and rich observability features for distributed storage and event-driven systems.
+
+## Features
+
+- **Multi-Target Fan-Out:** Dispatch audit logs to multiple targets (e.g., Webhook, MQTT) concurrently.
+- **Hot Reload:** Dynamically reload configuration and update targets without downtime.
+- **Observability:** Collect metrics such as EPS (Events Per Second), average latency, error rate, and target success
+  rate.
+- **Performance Validation:** Validate system performance against requirements and receive optimization recommendations.
+- **Extensible Registry:** Manage audit targets with add, remove, enable, disable, and upsert operations.
+- **Global Singleton:** Easy-to-use global audit system and logger.
+- **Async & Thread-Safe:** Built on Tokio and Rust async primitives for high concurrency.
+
+## Getting Started
+
+### Add Dependency
+
+Add to your `Cargo.toml`:
+
+```toml
+[dependencies]
+rustfs-audit = "0.1"
+```
+
+### Basic Usage
+
+#### Initialize and Start Audit System
+
+```rust
+use rustfs_audit::{start_audit_system, AuditLogger};
+use rustfs_ecstore::config::Config;
+
+#[tokio::main]
+async fn main() {
+    let config = Config::load("path/to/config.toml").await.unwrap();
+    start_audit_system(config).await.unwrap();
+}
+```
+
+#### Log an Audit Entry
+
+```rust
+use rustfs_audit::{AuditEntry, AuditLogger, ApiDetails};
+use chrono::Utc;
+use rustfs_targets::EventName;
+
+let entry = AuditEntry::new(
+"v1".to_string(),
+Some("deployment-123".to_string()),
+Some("siteA".to_string()),
+Utc::now(),
+EventName::ObjectCreatedPut,
+Some("type".to_string()),
+"trigger".to_string(),
+ApiDetails::default (),
+);
+
+AuditLogger::log(entry).await;
+```
+
+#### Observability & Metrics
+
+```rust
+use rustfs_audit::{get_metrics_report, validate_performance};
+
+let report = get_metrics_report().await;
+println!("{}", report.format());
+
+let validation = validate_performance().await;
+println!("{}", validation.format());
+```
+
+## Configuration
+
+Targets are configured via TOML files and environment variables. Supported target types:
+
+- **Webhook**
+- **MQTT**
+
+Environment variables override file configuration.
+See [docs.rs/rustfs-audit](https://docs.rs/rustfs-audit/latest/rustfs_audit/) for details.
+
+## API Overview
+
+- `AuditSystem`: Main system for managing targets and dispatching logs.
+- `AuditRegistry`: Registry for audit targets.
+- `AuditEntry`: Audit log entry structure.
+- `ApiDetails`: API call details for audit logs.
+- `AuditLogger`: Global logger singleton.
+- `AuditMetrics`, `AuditMetricsReport`: Metrics and reporting.
+- `PerformanceValidation`: Performance validation and recommendations.
+
+## Observability
+
+- **Metrics:** EPS, average latency, error rate, target success rate, processed/failed events, config reloads, system
+  starts.
+- **Validation:** Checks if EPS ≥ 3000, latency ≤ 30ms, error rate ≤ 1%. Provides actionable recommendations.
