-# 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.
 
-- **🚫 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.
 
-- 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
-- Support major architectures: x86_64, aarch64 (ARM64), and other target platforms
-- Use conditional compilation for architecture-specific code
-- Use feature flags for platform-specific dependencies
-- Provide fallback implementations for unsupported platforms
-- Test on multiple architectures in CI/CD pipeline
-- Use explicit byte order conversion when dealing with binary data
-- Prefer `to_le_bytes()`, `from_le_bytes()` for consistent little-endian format
-- Use portable SIMD libraries like `wide` or `packed_simd`
-- Provide fallback implementations for non-SIMD architectures
-
-## Security Guidelines

-## 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 (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.

+
+  ```
+  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

+
+**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.

+# cargo test test_kms_api_comprehensive -- --nocapture
+```
+
+### 运行所有KMS测试
+```bash
+cd crates/e2e_test
+cargo test kms -- --nocapture
+```
+
+### 串行运行（避免端口冲突）
+```bash
+cd crates/e2e_test
+cargo test kms -- --nocapture --test-threads=1
+```
+
+## 🔧 测试配置
+
+### 环境变量
+```bash
+# 可选：自定义端口（默认使用9050）
+export RUSTFS_TEST_PORT=9050
+
+# 可选：自定义Vault端口（默认使用8200）
+export VAULT_TEST_PORT=8200
+
+# 可选：启用详细日志
+export RUST_LOG=debug
+```
+
+### 依赖的二进制文件路径
+
+测试会自动查找以下二进制文件：
+- `../../target/debug/rustfs` - RustFS服务器
+- `vault` - Vault (需要在PATH中)
+- `/Users/dandan/Library/Python/3.9/bin/awscurl` - AWS签名工具
+
+## 📋 测试流程说明
+
+### Local KMS测试流程
+1. **环境准备**：创建临时目录，设置KMS密钥存储路径
+2. **启动服务**：启动RustFS服务器，启用KMS功能
+3. **等待就绪**：检查端口监听和S3 API响应
+4. **配置KMS**：通过awscurl发送配置请求到admin API
+5. **启动KMS**：激活KMS服务
+6. **功能测试**：
+   - 创建测试存储桶
+   - 测试SSE-C加密（客户端提供密钥）
+   - 验证对象加密/解密
+7. **清理**：终止进程，清理临时文件
+
+### Vault KMS测试流程
+1. **启动Vault**：使用开发模式启动Vault服务器
+2. **配置Vault**：
+   - 启用transit secrets engine
+   - 创建加密密钥（rustfs-master-key）
+3. **启动RustFS**：启用KMS功能的RustFS服务器
+4. **配置KMS**：通过API配置Vault后端，包含：
+   - Vault地址和Token认证
+   - Transit engine配置
+   - 密钥路径设置
+5. **功能测试**：完整的加密/解密流程测试
+6. **清理**：终止所有进程
+
+## 🛠️ 故障排除
+
+### 常见问题
+
+**Q: 测试失败 "RustFS server failed to become ready"**
+```
+A: 检查端口是否被占用：
+lsof -i :9050
+kill -9 <PID>  # 如果有进程占用端口
+```
+
+**Q: Vault服务启动失败**
+```
+A: 确保Vault已安装且在PATH中：
+which vault
+vault version
+```
+
+**Q: awscurl认证失败**
+```
+A: 检查awscurl路径是否正确：
+ls /Users/dandan/Library/Python/3.9/bin/awscurl
+# 或安装到不同路径：
+pip install awscurl
+which awscurl  # 然后更新测试中的路径
+```
+
+**Q: 测试超时**
+```
+A: 增加等待时间或检查日志：
+RUST_LOG=debug cargo test test_local_kms_end_to_end -- --nocapture
+```
+
+### 调试技巧
+
+1. **查看详细日志**：
+   ```bash
+   RUST_LOG=rustfs_kms=debug,rustfs=info cargo test -- --nocapture
+   ```
+
+2. **保留临时文件**：
+   修改测试代码，注释掉清理部分，检查生成的配置文件
+
+3. **单步调试**：
+   在测试中添加 `std::thread::sleep` 来暂停执行，手动检查服务状态
+
+4. **端口检查**：
+   ```bash
+   # 测试运行时检查端口状态
+   netstat -an | grep 9050
+   curl http://127.0.0.1:9050/minio/health/ready
+   ```
