+# RustFS Project AI Coding Rules
+
+## 🚨🚨🚨 CRITICAL DEVELOPMENT RULES - ZERO TOLERANCE 🚨🚨🚨
+
+### ⛔️ ABSOLUTE PROHIBITION: NEVER COMMIT DIRECTLY TO MASTER/MAIN BRANCH ⛔️
+
+**🔥 THIS IS THE MOST CRITICAL RULE - VIOLATION WILL RESULT IN IMMEDIATE REVERSAL 🔥**
+
+- **🚫 ZERO DIRECT COMMITS TO MAIN/MASTER BRANCH - ABSOLUTELY FORBIDDEN**
+- **🚫 ANY DIRECT COMMIT TO MAIN BRANCH MUST BE IMMEDIATELY REVERTED**
+- **🚫 NO EXCEPTIONS FOR HOTFIXES, EMERGENCIES, OR URGENT CHANGES**
+- **🚫 NO EXCEPTIONS FOR SMALL CHANGES, TYPOS, OR DOCUMENTATION UPDATES**
+- **🚫 NO EXCEPTIONS FOR ANYONE - MAINTAINERS, CONTRIBUTORS, OR ADMINS**
+
+### 📋 MANDATORY WORKFLOW - STRICTLY ENFORCED
+
+**EVERY SINGLE CHANGE MUST FOLLOW THIS WORKFLOW:**
+
+1. **Check current branch**: `git branch` (MUST NOT be on main/master)
+2. **Switch to main**: `git checkout main`
+3. **Pull latest**: `git pull origin main`
+4. **Create feature branch**: `git checkout -b feat/your-feature-name`
+5. **Make changes ONLY on feature branch**
+6. **Test thoroughly before committing**
+7. **Commit and push to feature branch**: `git push origin feat/your-feature-name`
+8. **Create Pull Request**: Use `gh pr create` (MANDATORY)
+9. **Wait for PR approval**: NO self-merging allowed
+10. **Merge through GitHub interface**: ONLY after approval
+
+### 🔒 ENFORCEMENT MECHANISMS
+
+- **Branch protection rules**: Main branch is protected
+- **Pre-commit hooks**: Will block direct commits to main
+- **CI/CD checks**: All PRs must pass before merging
+- **Code review requirement**: At least one approval needed
+- **Automated reversal**: Direct commits to main will be automatically reverted
+
+## 🎯 Core AI Development Principles
+
+### Five Execution Steps
+
+#### 1. Task Analysis and Planning
+- **Clear Objectives**: Deeply understand task requirements and expected results before starting coding
+- **Plan Development**: List specific files, components, and functions that need modification, explaining the reasons for changes
+- **Risk Assessment**: Evaluate the impact of changes on existing functionality, develop rollback plans
+
+#### 2. Precise Code Location
+- **File Identification**: Determine specific files and line numbers that need modification
+- **Impact Analysis**: Avoid modifying irrelevant files, clearly state the reason for each file modification
+- **Minimization Principle**: Unless explicitly required by the task, do not create new abstraction layers or refactor existing code
+
+#### 3. Minimal Code Changes
+- **Focus on Core**: Only write code directly required by the task
+- **Avoid Redundancy**: Do not add unnecessary logs, comments, tests, or error handling
+- **Isolation**: Ensure new code does not interfere with existing functionality, maintain code independence
+
+#### 4. Strict Code Review
+- **Correctness Check**: Verify the correctness and completeness of code logic
+- **Style Consistency**: Ensure code conforms to established project coding style
+- **Side Effect Assessment**: Evaluate the impact of changes on downstream systems
+
+#### 5. Clear Delivery Documentation
+- **Change Summary**: Detailed explanation of all modifications and reasons
+- **File List**: List all modified files and their specific changes
+- **Risk Statement**: Mark any assumptions or potential risk points
+
+### Core Principles
+- **🎯 Precise Execution**: Strictly follow task requirements, no arbitrary innovation
+- **⚡ Efficient Development**: Avoid over-design, only do necessary work
+- **🛡️ Safe and Reliable**: Always follow development processes, ensure code quality and system stability
+- **🔒 Cautious Modification**: Only modify when clearly knowing what needs to be changed and having confidence
+
+### Additional AI Behavior Rules
+
+1. **Use English for all code comments and documentation** - All comments, variable names, function names, documentation, and user-facing text in code should be in English
+2. **Clean up temporary scripts after use** - Any temporary scripts, test files, or helper files created during AI work should be removed after task completion
+3. **Only make confident modifications** - Do not make speculative changes or "convenient" modifications outside the task scope. If uncertain about a change, ask for clarification rather than guessing
+
+## 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
+
+## 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
+```
+
+### 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
+
+### 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 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(())
+}
+```
+
+## 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);
+    }
+}
+```
+
+### 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 struct Config {
+    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
+
+## Branch Management and Development Workflow
+
+### 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 .rules.md 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 Documentation Generation Restrictions
+
+### Forbidden Summary Documents
+
+- **Strictly forbidden to create any form of AI-generated summary documents**
+- **Do not create documents containing large amounts of emoji, detailed formatting tables and typical AI style**
+- **Do not generate the following types of documents in the project:**
+  - Benchmark summary documents (BENCHMARK*.md)
+  - Implementation comparison analysis documents (IMPLEMENTATION_COMPARISON*.md)
+  - Performance analysis report documents
+  - Architecture summary documents
+  - Feature comparison documents
+  - Any documents with large amounts of emoji and formatted content
+- **If documentation is needed, only create when explicitly requested by the user, and maintain a concise and practical style**
+- **Documentation should focus on actually needed information, avoiding excessive formatting and decorative content**
+- **Any discovered AI-generated summary documents should be immediately deleted**
+
+### Allowed Documentation Types
+
+- README.md (project introduction, keep concise)
+- Technical documentation (only create when explicitly needed)
+- User manual (only create when explicitly needed)
+- API documentation (generated from code)
+- Changelog (CHANGELOG.md)
+
+These rules should serve as guiding principles when developing the RustFS project, ensuring code quality, performance, and maintainability.

-# RustFS Project AI Agents Rules
+# Repository Guidelines
 
-## 🚨🚨🚨 CRITICAL DEVELOPMENT RULES - ZERO TOLERANCE 🚨🚨🚨
+## Communication Rules
+- Respond to the user in Chinese; use English in all other contexts.
 
-### ⛔️ ABSOLUTE PROHIBITION: NEVER COMMIT DIRECTLY TO MASTER/MAIN BRANCH ⛔️
+## 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.
 
-**🔥 THIS IS THE MOST CRITICAL RULE - VIOLATION WILL RESULT IN IMMEDIATE REVERSAL 🔥**
+## 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.
 
-- **🚫 ZERO DIRECT COMMITS TO MAIN/MASTER BRANCH - ABSOLUTELY FORBIDDEN**
-- **🚫 ANY DIRECT COMMIT TO MAIN BRANCH MUST BE IMMEDIATELY REVERTED**
-- **🚫 NO EXCEPTIONS FOR HOTFIXES, EMERGENCIES, OR URGENT CHANGES**
-- **🚫 NO EXCEPTIONS FOR SMALL CHANGES, TYPOS, OR DOCUMENTATION UPDATES**
-- **🚫 NO EXCEPTIONS FOR ANYONE - MAINTAINERS, CONTRIBUTORS, OR ADMINS**
-
-### 📋 MANDATORY WORKFLOW - STRICTLY ENFORCED
-
-**EVERY SINGLE CHANGE MUST FOLLOW THIS WORKFLOW:**
-
-1. **Check current branch**: `git branch` (MUST NOT be on main/master)
-2. **Switch to main**: `git checkout main`
-3. **Pull latest**: `git pull origin main`
-4. **Create feature branch**: `git checkout -b feat/your-feature-name`
-5. **Make changes ONLY on feature branch**
-6. **Test thoroughly before committing**
-7. **Commit and push to feature branch**: `git push origin feat/your-feature-name`
-8. **Create Pull Request**: Use `gh pr create` (MANDATORY)
-9. **Wait for PR approval**: NO self-merging allowed
-10. **Merge through GitHub interface**: ONLY after approval
-
-### 🔒 ENFORCEMENT MECHANISMS
-
-- **Branch protection rules**: Main branch is protected
-- **Pre-commit hooks**: Will block direct commits to main
-- **CI/CD checks**: All PRs must pass before merging
-- **Code review requirement**: At least one approval needed
-- **Automated reversal**: Direct commits to main will be automatically reverted
-
-## 🎯 Core Development Principles (HIGHEST PRIORITY)
-
-### Philosophy
-
-#### Core Beliefs
-
-- **Incremental progress over big bangs** - Small changes that compile and pass tests
-- **Learning from existing code** - Study and plan before implementing
-- **Pragmatic over dogmatic** - Adapt to project reality
-- **Clear intent over clever code** - Be boring and obvious
-
-#### Simplicity Means
-
-- Single responsibility per function/class
-- Avoid premature abstractions
-- No clever tricks - choose the boring solution
-- If you need to explain it, it's too complex
-
-### Process
-
-#### 1. Planning & Staging
-
-Break complex work into 3-5 stages. Document in `IMPLEMENTATION_PLAN.md`:
-
-```markdown
-## Stage N: [Name]
-**Goal**: [Specific deliverable]
-**Success Criteria**: [Testable outcomes]
-**Tests**: [Specific test cases]
-**Status**: [Not Started|In Progress|Complete]
-```
-
-- Update status as you progress
-- Remove file when all stages are done
-
-#### 2. Implementation Flow
-
-1. **Understand** - Study existing patterns in codebase
-2. **Test** - Write test first (red)
-3. **Implement** - Minimal code to pass (green)
-4. **Refactor** - Clean up with tests passing
-5. **Commit** - With clear message linking to plan
-
-#### 3. When Stuck (After 3 Attempts)
-
-**CRITICAL**: Maximum 3 attempts per issue, then STOP.
-
-1. **Document what failed**:
-   - What you tried
-   - Specific error messages
-   - Why you think it failed
-
-2. **Research alternatives**:
-   - Find 2-3 similar implementations
-   - Note different approaches used
-
-3. **Question fundamentals**:
-   - Is this the right abstraction level?
-   - Can this be split into smaller problems?
-   - Is there a simpler approach entirely?
-
-4. **Try different angle**:
-   - Different library/framework feature?
-   - Different architectural pattern?
-   - Remove abstraction instead of adding?
-
-### Technical Standards
-
-#### Architecture Principles
-
-- **Composition over inheritance** - Use dependency injection
-- **Interfaces over singletons** - Enable testing and flexibility
-- **Explicit over implicit** - Clear data flow and dependencies
-- **Test-driven when possible** - Never disable tests, fix them
-
-#### Code Quality
-
-- **Every commit must**:
-  - Compile successfully
-  - Pass all existing tests
-  - Include tests for new functionality
-  - Follow project formatting/linting
-
-- **Before committing**:
-  - Run formatters/linters
-  - Self-review changes
-  - Ensure commit message explains "why"
-
-#### Error Handling
-
-- Fail fast with descriptive messages
-- Include context for debugging
-- Handle errors at appropriate level
-- Never silently swallow exceptions
-
-### Decision Framework
-
-When multiple valid approaches exist, choose based on:
-
-1. **Testability** - Can I easily test this?
-2. **Readability** - Will someone understand this in 6 months?
-3. **Consistency** - Does this match project patterns?
-4. **Simplicity** - Is this the simplest solution that works?
-5. **Reversibility** - How hard to change later?
-
-### Project Integration
-
-#### Learning the Codebase
-
-- Find 3 similar features/components
-- Identify common patterns and conventions
-- Use same libraries/utilities when possible
-- Follow existing test patterns
-
-#### Tooling
-
-- Use project's existing build system
-- Use project's test framework
-- Use project's formatter/linter settings
-- Don't introduce new tools without strong justification
-
-### Quality Gates
-
-#### Definition of Done
-
-- [ ] Tests written and passing
-- [ ] Code follows project conventions
-- [ ] No linter/formatter warnings
-- [ ] Commit messages are clear
-- [ ] Implementation matches plan
-- [ ] No TODOs without issue numbers
-
-#### Test Guidelines
-
-- Test behavior, not implementation
-- One assertion per test when possible
-- Clear test names describing scenario
-- Use existing test utilities/helpers
-- Tests should be deterministic
-
-### Important Reminders
-
-**NEVER**:
-
-- Use `--no-verify` to bypass commit hooks
-- Disable tests instead of fixing them
-- Commit code that doesn't compile
-- Make assumptions - verify with existing code
-
-**ALWAYS**:
-
-- Commit working code incrementally
-- Update plan documentation as you go
-- Learn from existing implementations
-- Stop after 3 failed attempts and reassess
-
-## 🚫 Competitor Keywords Prohibition
-
-### Strictly Forbidden Keywords
-
-**CRITICAL**: The following competitor keywords are absolutely forbidden in any code, documentation, comments, or project files:
-
-- **minio** (and any variations like MinIO, MINIO)
-- **aws-s3** (when referring to competing implementations)
-- **ceph** (and any variations like Ceph, CEPH)
-- **swift** (OpenStack Swift)
-- **glusterfs** (and any variations like GlusterFS, Gluster)
-- **seaweedfs** (and any variations like SeaweedFS, Seaweed)
-- **garage** (and any variations like Garage)
-- **zenko** (and any variations like Zenko)
-- **scality** (and any variations like Scality)
-
-### Enforcement
-
-- **Code Review**: All PRs will be checked for competitor keywords
-- **Automated Scanning**: CI/CD pipeline will scan for forbidden keywords
-- **Immediate Rejection**: Any PR containing competitor keywords will be immediately rejected
-- **Documentation**: All documentation must use generic terms like "S3-compatible storage" instead of specific competitor names
-
-### Acceptable Alternatives
-
-Instead of competitor names, use these generic terms:
-
-- "S3-compatible storage system"
-- "Object storage solution"
-- "Distributed storage platform"
-- "Cloud storage service"
-- "Storage backend"
-
-## 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
-
-## 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
-```
-
-### 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
-
-### 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
-
-- 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
-- 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
-
-- Use `#[tracing::instrument(skip(self, data))]` for function tracing
-- Log levels: `error!` (system errors), `warn!` (warnings), `info!` (business info), `debug!` (development), `trace!` (detailed paths)
-- Use structured logging with key-value pairs for better observability
-
-## Error Handling Guidelines
-
-- Use `thiserror` for module-specific error types
-- 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
-
-## Performance Optimization Guidelines
-
-- Use `Bytes` instead of `Vec<u8>` for zero-copy operations
-- Avoid unnecessary cloning, use reference passing
-- Use `Arc` for sharing large objects
-- Use `join_all` for concurrent operations
-- Use `LazyLock` for global caching
-- Implement LRU cache to avoid memory leaks
+## 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.
 
-- 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
-- Use `e2e_test` module for end-to-end testing
-- Simulate real storage environments
+## 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.
 
-## Cross-Platform Compatibility Guidelines
-
-- **Always consider multi-platform and different CPU architecture compatibility** when writing code

-   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 Documentation Generation Restrictions
-
-### Forbidden Summary Documents
-
-- **Strictly forbidden to create any form of AI-generated summary documents**
-- **Do not create documents containing large amounts of emoji, detailed formatting tables and typical AI style**
-- **Do not generate the following types of documents in the project:**
-  - Benchmark summary documents (BENCHMARK*.md)
-  - Implementation comparison analysis documents (IMPLEMENTATION_COMPARISON*.md)
-  - Performance analysis report documents
-  - Architecture summary documents
-  - Feature comparison documents
-  - Any documents with large amounts of emoji and formatted content
-- **If documentation is needed, only create when explicitly requested by the user, and maintain a concise and practical style**
-- **Documentation should focus on actually needed information, avoiding excessive formatting and decorative content**
-- **Any discovered AI-generated summary documents should be immediately deleted**
-
-### Allowed Documentation Types
-
-- README.md (project introduction, keep concise)
-- Technical documentation (only create when explicitly needed)
-- User manual (only create when explicitly needed)
-- API documentation (generated from code)
-- Changelog (CHANGELOG.md)
-
-These rules should serve as guiding principles when developing the RustFS project, ensuring code quality, performance, and maintainability.
+## 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

+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.

+
+**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.

+# KMS End-to-End Tests
+
+This directory contains the integration suites used to validate the full RustFS KMS (Key Management Service) workflow.
+
+## 📁 Test Overview
+
+### `kms_local_test.rs`
+End-to-end coverage for the local KMS backend:
+- Auto-start and configure the local backend
+- Configure KMS through the dynamic configuration API
+- Verify SSE-C (client-provided keys)
+- Exercise S3-compatible encryption/decryption
+- Validate key lifecycle management
+
+### `kms_vault_test.rs`
+End-to-end coverage for the Vault backend:
+- Launch a Vault dev server automatically
+- Configure the transit engine and encryption keys
+- Configure KMS via the dynamic configuration API
+- Run the full Vault integration flow
+- Validate token authentication and encryption operations
+
+### `kms_comprehensive_test.rs`
+**Full KMS capability suite** (currently disabled because of AWS SDK compatibility issues):
+- **Bucket encryption configuration**: SSE-S3 and SSE-KMS defaults
+- **All SSE encryption modes**:
+  - SSE-S3 (S3-managed server-side encryption)
+  - SSE-KMS (KMS-managed server-side encryption)
+  - SSE-C (client-provided keys)
+- **Object operations**: upload, download, and validation for every SSE mode
+- **Multipart uploads**: cover each SSE mode
+- **Object replication**: cross-mode replication scenarios
+- **Complete KMS API management**:
+  - Key lifecycle (create, list, describe, delete, cancel delete)
+  - Direct encrypt/decrypt operations
+  - Data key generation and handling
+  - KMS service lifecycle (start, stop, status)
+
+### `kms_integration_test.rs`
+Broad integration tests that exercise:
+- Multiple backends
+- KMS lifecycle management
+- Error handling and recovery
+- **Note**: currently disabled because of AWS SDK compatibility gaps
+

+
+# Optional: custom Vault port (default 8200)
+export VAULT_TEST_PORT=8200
+
+# Optional: enable verbose logging
+export RUST_LOG=debug
+```
+
+### Required binaries
+
+Tests look for:
+- `../../target/debug/rustfs` – RustFS server
+- `vault` – Vault CLI (must be on PATH)
+- `/Users/dandan/Library/Python/3.9/bin/awscurl` – AWS SigV4 helper
+
+## 📋 Test Flow
+
+### Local backend
+1. **Prepare environment** – create temporary directories and key storage paths
+2. **Start RustFS** – launch the server with KMS enabled
+3. **Wait for readiness** – confirm the port listener and S3 API
+4. **Configure KMS** – send configuration via awscurl to the admin API
+5. **Start KMS** – activate the KMS service
+6. **Exercise functionality**
+   - Create a test bucket
+   - Run SSE-C encryption with client-provided keys
+   - Validate encryption/decryption behavior
+7. **Cleanup** – stop processes and remove temporary files
+
+### Vault backend
+1. **Launch Vault** – start the dev-mode server
+2. **Configure Vault**
+   - Enable the transit secrets engine
+   - Create the `rustfs-master-key`
+3. **Start RustFS** – run the server with KMS enabled
+4. **Configure KMS** – point RustFS at Vault (address, token, transit config, key path)
+5. **Exercise functionality** – complete the encryption/decryption workflow
+6. **Cleanup** – stop all services
+
+## 🛠️ Troubleshooting
+
+### Common issues
+
+**Q: `RustFS server failed to become ready`**
+```bash
+lsof -i :9050
+kill -9 <PID>  # Free the port if necessary
+```
+
+**Q: Vault fails to start**
+```bash
+which vault
+vault version
+```
+
+**Q: awscurl authentication fails**
+```bash
+ls /Users/dandan/Library/Python/3.9/bin/awscurl
+# Or install elsewhere
+pip install awscurl
+which awscurl  # Update the path in tests accordingly
+```
+
+**Q: Tests time out**
+```bash
+RUST_LOG=debug cargo test test_local_kms_end_to_end -- --nocapture
+```
+
+### Debug tips
+
+1. **Enable verbose logs**
+   ```bash
+   RUST_LOG=rustfs_kms=debug,rustfs=info cargo test -- --nocapture
+   ```
+
+2. **Keep temporary files** – comment out cleanup logic to inspect generated configs
+
+3. **Pause execution** – add `std::thread::sleep` for manual inspection during tests
+
+4. **Monitor ports**
+   ```bash
+   netstat -an | grep 9050
+   curl http://127.0.0.1:9050/minio/health/ready
+   ```
