+# 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
+}
+```
+
+## Code Review Checklist

+
+## 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.

-## 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 AGENTS.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.
+## 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 Environment Variables
+
+- `NO_PROXY=127.0.0.1,localhost` - Required for KMS E2E tests to bypass proxy
+- `HTTP_PROXY=` `HTTPS_PROXY=` `http_proxy=` `https_proxy=` - Clear proxy settings for local KMS testing
+
+## 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.

 ## Quickstart
 
 To get started with RustFS, follow these steps:
 
-1. **One-click installation script (Option 1)​​**
+### 1. One-click Installation (Option 1)
 
   ```bash
-  curl -O  https://rustfs.com/install_rustfs.sh && bash install_rustfs.sh
-  ```
+  curl -O https://rustfs.com/install_rustfs.sh && bash install_rustfs.sh
+````
 
-2. **Docker Quick Start (Option 2)​​**
+### 2\. Docker Quick Start (Option 2)
 
-  ```bash
-   # create data and logs directories
-   mkdir -p data logs
+The RustFS container runs as a non-root user `rustfs` (UID `10001`). If you run Docker with `-v` to mount a host directory, please ensure the host directory owner is set to `10001`, otherwise you will encounter permission denied errors.
 
-   # using latest alpha version
-   docker run -d -p 9000:9000 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:alpha
+```bash
+ # Create data and logs directories
+ mkdir -p data logs
 
-   # Specific version
-   docker run -d -p 9000:9000 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:1.0.0.alpha.45
-   ```
+ # Change the owner of these directories
+ chown -R 10001:10001 data logs
 
-  For docker installation, you can also run the container with docker compose. With the `docker-compose.yml` file under root directory, running the command:
+ # Using latest version
+ docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:latest
 
-  ```
-  docker compose --profile observability up -d
-  ```
-  
-  **NOTE**: You should be better to have a look for `docker-compose.yaml` file. Because, several services contains in the file. Grafan,prometheus,jaeger containers will be launched using docker compose file, which is helpful for rustfs observability. If you want to start redis as well as nginx container, you can specify the corresponding profiles.
+ # Using specific version
+ docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:1.0.0.alpha.68
+```
 
-3. **Build from Source (Option 3) - Advanced Users**
+You can also use Docker Compose. Using the `docker-compose.yml` file in the root directory:
 
-   For developers who want to build RustFS Docker images from source with multi-architecture support:
+```bash
+docker compose --profile observability up -d
+```
 
-   ```bash
-   # Build multi-architecture images locally
-   ./docker-buildx.sh --build-arg RELEASE=latest
+**NOTE**: We recommend reviewing the `docker-compose.yaml` file before running. It defines several services including Grafana, Prometheus, and Jaeger, which are helpful for RustFS observability. If you wish to start Redis or Nginx containers, you can specify the corresponding profiles.
 
-   # Build and push to registry
-   ./docker-buildx.sh --push
+### 3\. Build from Source (Option 3) - Advanced Users
 
-   # Build specific version
-   ./docker-buildx.sh --release v1.0.0 --push
+For developers who want to build RustFS Docker images from source with multi-architecture support:
 
-   # Build for custom registry
-   ./docker-buildx.sh --registry your-registry.com --namespace yourname --push
-   ```
+```bash
+# Build multi-architecture images locally
+./docker-buildx.sh --build-arg RELEASE=latest
 
-   The `docker-buildx.sh` script supports:
-   - **Multi-architecture builds**: `linux/amd64`, `linux/arm64`
-   - **Automatic version detection**: Uses git tags or commit hashes
-   - **Registry flexibility**: Supports Docker Hub, GitHub Container Registry, etc.
-   - **Build optimization**: Includes caching and parallel builds
+# Build and push to registry
+./docker-buildx.sh --push
 
-   You can also use Make targets for convenience:
+# Build specific version
+./docker-buildx.sh --release v1.0.0 --push
 
-   ```bash
-   make docker-buildx                    # Build locally
-   make docker-buildx-push               # Build and push
-   make docker-buildx-version VERSION=v1.0.0  # Build specific version
-   make help-docker                      # Show all Docker-related commands
-   ```
+# Build for custom registry
+./docker-buildx.sh --registry your-registry.com --namespace yourname --push
+```
 
-4. **Access the Console**: Open your web browser and navigate to `http://localhost:9000` to access the RustFS console, default username and password is `rustfsadmin` .
-5. **Create a Bucket**: Use the console to create a new bucket for your objects.
-6. **Upload Objects**: You can upload files directly through the console or use S3-compatible APIs to interact with your RustFS instance.
+The `docker-buildx.sh` script supports:
+\- **Multi-architecture builds**: `linux/amd64`, `linux/arm64`
+\- **Automatic version detection**: Uses git tags or commit hashes
+\- **Registry flexibility**: Supports Docker Hub, GitHub Container Registry, etc.
+\- **Build optimization**: Includes caching and parallel builds
 
-**NOTE**: If you want to access RustFS instance with `https`, you can refer to [TLS configuration docs](https://docs.rustfs.com/integration/tls-configured.html).
+You can also use Make targets for convenience:
+
+```bash
+make docker-buildx                    # Build locally
+make docker-buildx-push               # Build and push
+make docker-buildx-version VERSION=v1.0.0  # Build specific version
+make help-docker                      # Show all Docker-related commands
+```
+
+> **Heads-up (macOS cross-compilation)**: macOS keeps the default `ulimit -n` at 256, so `cargo zigbuild` or `./build-rustfs.sh --platform ...` may fail with `ProcessFdQuotaExceeded` when targeting Linux. The build script attempts to raise the limit automatically, but if you still see the warning, run `ulimit -n 4096` (or higher) in your shell before building.
+
+### 4\. Build with Helm Chart (Option 4) - Cloud Native
+
+Follow the instructions in the [Helm Chart README](https://charts.rustfs.com/) to install RustFS on a Kubernetes cluster.
+
+-----
+
+### Accessing RustFS
+
+5.  **Access the Console**: Open your web browser and navigate to `http://localhost:9000` to access the RustFS console.
+      * Default credentials: `rustfsadmin` / `rustfsadmin`
+6.  **Create a Bucket**: Use the console to create a new bucket for your objects.
+7.  **Upload Objects**: You can upload files directly through the console or use S3-compatible APIs/clients to interact with your RustFS instance.
+
+**NOTE**: To access the RustFS instance via `https`, please refer to the [TLS Configuration Docs](https://docs.rustfs.com/integration/tls-configured.html).

 ## 快速开始
 
-要开始使用 RustFS，请按照以下步骤操作：
+请按照以下步骤快速上手 RustFS：
 
-1. **一键脚本快速启动 (方案一)**
-
-   ```bash
-   curl -O  https://rustfs.com/install_rustfs.sh && bash install_rustfs.sh
-   ```
-
-2. **Docker快速启动（方案二）**
+### 1. 一键安装脚本 (选项 1)
 
   ```bash
-   docker run -d -p 9000:9000  -v /data:/data rustfs/rustfs
-   ```
+  curl -O https://rustfs.com/install_rustfs.sh && bash install_rustfs.sh
+````
 
-  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：
+### 2\. Docker 快速启动 (选项 2)
 
-  ```
-  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。
+RustFS 容器以非 root 用户 `rustfs` (UID `10001`) 运行。如果您使用 Docker 的 `-v` 参数挂载宿主机目录，请务必确保宿主机目录的所有者已更改为 `1000`，否则会遇到权限拒绝错误。
 
-3. **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 `rustfsadmin` 。
-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。
+```bash
+ # 创建数据和日志目录
+ mkdir -p data logs
 
-**注意**：如果你想通过 `https` 来访问 RustFS 实例，请参考 [TLS 配置文档](https://docs.rustfs.com/zh/integration/tls-configured.html)
+ # 更改这两个目录的所有者
+ chown -R 10001:10001 data logs
+
+ # 使用最新版本运行
+ docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:latest
+
+ # 使用指定版本运行
+ docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:1.0.0.alpha.68
+```
+
+您也可以使用 Docker Compose。使用根目录下的 `docker-compose.yml` 文件：
+
+```bash
+docker compose --profile observability up -d
+```
+
+**注意**: 我们建议您在运行前查看 `docker-compose.yaml` 文件。该文件定义了包括 Grafana、Prometheus 和 Jaeger 在内的多个服务，有助于 RustFS 的可观测性监控。如果您还想启动 Redis 或 Nginx 容器，可以指定相应的 profile。
+
+### 3\. 源码编译 (选项 3) - 进阶用户
+
+适用于希望从源码构建支持多架构 RustFS Docker 镜像的开发者：
+
+```bash
+# 在本地构建多架构镜像
+./docker-buildx.sh --build-arg RELEASE=latest
+
+# 构建并推送到仓库
+./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**: 使用 git tags 或 commit hash
+\- **灵活的仓库支持**: 支持 Docker Hub, GitHub Container Registry 等
+\- **构建优化**: 包含缓存和并行构建
+
+为了方便起见，您也可以使用 Make 命令：
+
+```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                      # 显示所有 Docker 相关命令
+```
+
+> **注意 (macOS 交叉编译)**: macOS 默认的 `ulimit -n` 限制为 256，因此在使用 `cargo zigbuild` 或 `./build-rustfs.sh --platform ...` 交叉编译 Linux 版本时，可能会因 `ProcessFdQuotaExceeded` 失败。构建脚本会尝试自动提高限制，但如果您仍然看到警告，请在构建前在终端运行 `ulimit -n 4096` (或更高)。
+
+### 4\. 使用 Helm Chart 安装 (选项 4) - 云原生环境
+
+请按照 [Helm Chart README](https://charts.rustfs.com) 上的说明在 Kubernetes 集群上安装 RustFS。
+
+-----
+
+### 访问 RustFS
+
+5.  **访问控制台**: 打开浏览器并访问 `http://localhost:9000` 进入 RustFS 控制台。
+      * 默认账号/密码: `rustfsadmin` / `rustfsadmin`
+6.  **创建存储桶**: 使用控制台为您​​的对象创建一个新的存储桶 (Bucket)。
+7.  **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/客户端与您的 RustFS 实例进行交互。
+
+**注意**: 如果您希望通过 `https` 访问 RustFS 实例，请参考 [TLS 配置文档](https://docs.rustfs.com/integration/tls-configured.html)。

+
+**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.
