+# OpenStack Swift API for RustFS
+
+Swift-compatible object storage API implementation for RustFS.
+
+## Features
+
+This implementation provides **Phase 1 Swift API support** (~25% of full Swift API):
+
+- ✅ Container CRUD operations (create, list, delete, metadata)
+- ✅ Object CRUD with streaming downloads (upload, get, head, delete)
+- ✅ Keystone token authentication
+- ✅ Multi-tenant isolation with secure SHA256-based bucket prefixing
+- ✅ Server-side object copy (COPY method)
+- ✅ HTTP Range requests for partial downloads (206, 416 responses)
+- ✅ Custom metadata support (X-Object-Meta-*, X-Container-Meta-*)
+
+**Not yet implemented:**
+- ⏳ Account-level operations (statistics, metadata)
+- ⏳ Large object support (multi-part uploads >5GB)
+- ⏳ Object versioning
+- ⏳ Container ACLs and CORS
+- ⏳ Temporary URLs (TempURL)
+- ⏳ XML/plain-text response formats (JSON only)
+
+## Enable Feature
+
+**Swift API is opt-in and must be explicitly enabled.**
+
+Build with Swift support:
+
+```bash
+cargo build --features swift
+```
+
+Or enable all protocol features:
+
+```bash
+cargo build --features full
+```
+
+**Note:** Swift is NOT enabled by default to avoid unexpected API surface changes in existing deployments.
+
+## Configuration
+
+Swift API uses Keystone for authentication. Configure the following environment variables:
+
+| Variable | Description |
+|----------|-------------|
+| `RUSTFS_KEYSTONE_URL` | Keystone authentication endpoint URL |
+| `RUSTFS_KEYSTONE_ADMIN_TENANT` | Admin tenant/project name |
+| `RUSTFS_KEYSTONE_ADMIN_USER` | Admin username |
+| `RUSTFS_KEYSTONE_ADMIN_PASSWORD` | Admin password |
+
+## API Endpoints
+
+Swift API endpoints follow the pattern: `/v1/AUTH_{project_id}/...`
+
+### Account Operations
+- `GET /v1/AUTH_{project}` - List containers
+- `HEAD /v1/AUTH_{project}` - Get account metadata (not yet implemented)
+- `POST /v1/AUTH_{project}` - Update account metadata (not yet implemented)
+
+### Container Operations
+- `PUT /v1/AUTH_{project}/{container}` - Create container
+- `GET /v1/AUTH_{project}/{container}` - List objects
+- `HEAD /v1/AUTH_{project}/{container}` - Get container metadata
+- `POST /v1/AUTH_{project}/{container}` - Update container metadata
+- `DELETE /v1/AUTH_{project}/{container}` - Delete container
+
+### Object Operations
+- `PUT /v1/AUTH_{project}/{container}/{object}` - Upload object
+- `GET /v1/AUTH_{project}/{container}/{object}` - Download object
+- `HEAD /v1/AUTH_{project}/{container}/{object}` - Get object metadata
+- `POST /v1/AUTH_{project}/{container}/{object}` - Update object metadata
+- `DELETE /v1/AUTH_{project}/{container}/{object}` - Delete object
+- `COPY /v1/AUTH_{project}/{container}/{object}` - Server-side copy
+
+## Architecture
+
+The Swift API is implemented as a Tower service layer (`SwiftService`) that wraps the S3 service:
+
+```
+HTTP Request
+    │
+    ▼
+┌───────────────┐
+│ SwiftService  │ ← Routes /v1/AUTH_* requests
+└───────┬───────┘
+        │
+   ┌────┴────┐
+   │         │
+   ▼         ▼
+Swift     S3 Service
+Handler   (fallback)
+```
+
+### Key Components
+
+- **handler.rs** - Main service implementing Tower's Service trait
+- **router.rs** - URL routing and parsing for Swift paths
+- **container.rs** - Container operations with tenant isolation
+- **object.rs** - Object operations including copy and range requests
+- **account.rs** - Account validation and tenant access control
+- **errors.rs** - Swift-specific error types
+- **types.rs** - Data structures for Swift API responses
+
+### Tenant Isolation
+
+Swift containers are mapped to S3 buckets with a secure hash prefix:
+
+```
+Swift: /v1/AUTH_abc123/mycontainer
+  ↓
+S3 Bucket: {sha256(abc123)[0:16]}-mycontainer
+```
+
+This ensures:
+- Complete tenant isolation at the storage layer
+- No collision between tenants with similar container names
+- S3-compatible bucket naming (lowercase alphanumeric + hyphen)
+
+## Documentation
+
+See the `docs/` directory for detailed documentation:
+
+- `SWIFT_API.md` - Complete API reference
+- `TESTING_GUIDE.md` - Manual testing procedures
+- `COMPLETION_ANALYSIS.md` - Protocol coverage tracking
+- `COPY_IMPLEMENTATION.md` - Server-side copy documentation
+- `RANGE_REQUESTS.md` - Range request implementation details

+//! Access Control List (ACL) Support for Swift API
+//!
+//! Implements Swift container ACLs for fine-grained access control.
+//!
+//! # ACL Types
+//!
+//! ## Read ACLs (X-Container-Read)
+//!
+//! - **Public read**: `.r:*` - Anyone can read
+//! - **Referrer restriction**: `.r:*.example.com` - Only specific referrers
+//! - **Account access**: `AUTH_project123` - Specific account
+//! - **User access**: `AUTH_project123:user1` - Specific user in account
+//!
+//! ## Write ACLs (X-Container-Write)
+//!
+//! - **Account access**: `AUTH_project123` - Specific account can write
+//! - **User access**: `AUTH_project123:user1` - Specific user can write
+//! - **No public write** - Public write is not supported for security
+//!
+//! # Examples
+//!
+//! ```text
+//! # Public read container
+//! X-Container-Read: .r:*
+//!
+//! # Referrer-restricted public read
+//! X-Container-Read: .r:*.example.com,.r:*.cdn.com
+//!
+//! # Specific accounts can read
+//! X-Container-Read: AUTH_abc123,AUTH_def456
+//!
+//! # Mixed ACL
+//! X-Container-Read: .r:*.example.com,AUTH_abc123,AUTH_def456:user1
+//!
+//! # Write access
+//! X-Container-Write: AUTH_abc123,AUTH_def456:user1
+//! ```
+//!
+//! # Storage
+//!
+//! ACLs are stored in S3 bucket tags:
+//! - Tag key: `swift-acl-read` with comma-separated grants
+//! - Tag key: `swift-acl-write` with comma-separated grants

+//! Bulk Operations for Swift API
+//!
+//! This module implements bulk operations that allow batch processing of
+//! multiple objects in a single request, improving efficiency for operations
+//! that affect many files.
+//!
+//! # Operations
+//!
+//! ## Bulk Delete
+//!
+//! Delete multiple objects in a single request.
+//!
+//! **Endpoint**: `DELETE /?bulk-delete`
+//!
+//! **Request Body**: Newline-separated list of object paths
+//! ```text
+//! /container1/object1.txt
+//! /container2/folder/object2.txt
+//! /container1/object3.txt
+//! ```
+//!
+//! **Response**: JSON with results for each object
+//! ```json
+//! {
+//!   "Number Deleted": 2,
+//!   "Number Not Found": 1,
+//!   "Errors": [],
+//!   "Response Status": "200 OK",
+//!   "Response Body": ""
+//! }
+//! ```
+//!
+//! ## Bulk Extract
+//!
+//! Extract files from an uploaded archive into a container.
+//!
+//! **Endpoint**: `PUT /{container}?extract-archive=tar` (or tar.gz, tar.bz2)
+//!
+//! **Request Body**: Archive file contents
+//!
+//! **Response**: JSON with results for each extracted file
+//! ```json
+//! {
+//!   "Number Files Created": 10,
+//!   "Errors": [],
+//!   "Response Status": "201 Created",
+//!   "Response Body": ""
+//! }
+//! ```
+//!
+//! # Examples
+//!
+//! ```bash
+//! # Bulk delete
+//! echo -e "/container/file1.txt\n/container/file2.txt" | \
+//!   swift delete --bulk
+//!
+//! # Bulk extract
+//! tar czf archive.tar.gz files/
+//! swift upload container --extract-archive archive.tar.gz
+//! ```

+
+//! CORS (Cross-Origin Resource Sharing) Support for Swift API
+//!
+//! This module implements CORS configuration and response header injection
+//! for Swift containers and objects, enabling web browsers to access Swift
+//! resources from different origins.
+//!
+//! # Configuration
+//!
+//! CORS is configured via container metadata:
+//!
+//! - `X-Container-Meta-Access-Control-Allow-Origin`: Allowed origins (e.g., `*` or `https://example.com`)
+//! - `X-Container-Meta-Access-Control-Max-Age`: Preflight cache duration in seconds
+//! - `X-Container-Meta-Access-Control-Expose-Headers`: Headers exposed to browser
+//! - `X-Container-Meta-Access-Control-Allow-Credentials`: Allow credentials (true/false)
+//!
+//! # Usage
+//!
+//! ```bash
+//! # Enable CORS for all origins
+//! swift post my-container \
+//!   -H "X-Container-Meta-Access-Control-Allow-Origin: *" \
+//!   -H "X-Container-Meta-Access-Control-Max-Age: 86400"
+//!
+//! # Enable CORS for specific origin
+//! swift post my-container \
+//!   -H "X-Container-Meta-Access-Control-Allow-Origin: https://example.com"
+//!
+//! # Expose custom headers
+//! swift post my-container \
+//!   -H "X-Container-Meta-Access-Control-Expose-Headers: X-Custom-Header, X-Another-Header"
+//! ```
+//!
+//! # Preflight Requests
+//!
+//! Browsers send OPTIONS requests for preflight checks. This module handles
+//! these requests by returning appropriate Access-Control-* headers based on
+//! container configuration.

+//! Server-Side Encryption Support for Swift API
+//!
+//! This module implements automatic server-side encryption for Swift objects,
+//! providing encryption at rest with transparent encryption/decryption.
+//!
+//! # Encryption Algorithm
+//!
+//! Uses AES-256-GCM (Galois/Counter Mode) which provides:
+//! - Confidentiality (AES-256 encryption)
+//! - Authenticity (built-in authentication tag)
+//! - Performance (hardware acceleration on modern CPUs)
+//!
+//! # Key Management
+//!
+//! Supports multiple key sources:
+//! - Environment variable (SWIFT_ENCRYPTION_KEY)
+//! - Configuration file
+//! - External KMS (future: Barbican, AWS KMS, HashiCorp Vault)
+//!
+//! # Usage
+//!
+//! Encryption is transparent to clients:
+//!
+//! ```bash
+//! # Objects automatically encrypted on upload
+//! swift upload container file.txt
+//!
+//! # Automatically decrypted on download
+//! swift download container file.txt
+//! ```
+//!
+//! # Metadata
+//!
+//! Encrypted objects include metadata:
+//! - `X-Object-Meta-Crypto-Enabled: true`
+//! - `X-Object-Meta-Crypto-Algorithm: AES-256-GCM`
+//! - `X-Object-Meta-Crypto-Key-Id: <key_id>`
+//! - `X-Object-Meta-Crypto-Iv: <base64_iv>`
+//!
+//! # Key Rotation
+//!
+//! Objects can be re-encrypted with new keys:
+//! - Upload with new key ID
+//! - Old encrypted objects remain readable with old keys
+//! - Gradual migration to new keys

+//! Object Expiration Support for Swift API
+//!
+//! This module implements automatic object expiration, allowing objects to be
+//! automatically deleted after a specified time. This is useful for temporary
+//! files, cache data, and time-limited content.
+//!
+//! # Configuration
+//!
+//! Object expiration is configured via headers during PUT or POST:
+//!
+//! - `X-Delete-At`: Unix timestamp when object should be deleted
+//! - `X-Delete-After`: Seconds from now when object should be deleted
+//!
+//! # Usage
+//!
+//! ```bash
+//! # Delete object at specific time (Unix timestamp)
+//! swift upload container file.txt -H "X-Delete-At: 1740000000"
+//!
+//! # Delete object 3600 seconds (1 hour) from now
+//! swift upload container file.txt -H "X-Delete-After: 3600"
+//!
+//! # Update expiration on existing object
+//! swift post container file.txt -H "X-Delete-At: 1750000000"
+//! ```
+//!
+//! # Expiration Headers
+//!
+//! When retrieving objects with expiration set:
+//! ```http
+//! GET /v1/AUTH_account/container/file.txt
+//!
+//! HTTP/1.1 200 OK
+//! X-Delete-At: 1740000000
+//! ```
+//!
+//! # Cleanup
+//!
+//! Expired objects are automatically deleted by a background worker that
+//! periodically scans for objects past their expiration time.

+//! Background Worker for Automatic Object Expiration Cleanup
+//!
+//! This module implements a background worker that periodically scans for and
+//! deletes expired objects based on their X-Delete-At metadata.
+//!
+//! # Architecture
+//!
+//! The worker uses a priority queue to efficiently track objects nearing expiration:
+//! - Objects with expiration timestamps are added to a min-heap
+//! - Worker periodically checks the heap for expired objects
+//! - Expired objects are deleted and removed from the heap
+//! - Incremental scanning prevents full table scans on each iteration
+//!
+//! # Configuration
+//!
+//! ```rust
+//! use rustfs_protocols::swift::expiration_worker::*;
+//!
+//! let config = ExpirationWorkerConfig {
+//!     scan_interval_secs: 300,      // Scan every 5 minutes
+//!     batch_size: 100,               // Process 100 objects per batch
+//!     max_workers: 4,                // Support distributed scanning
+//!     worker_id: 0,                  // This worker's ID (0-3)
+//! };
+//!
+//! let worker = ExpirationWorker::new(config);
+//! worker.start().await;
+//! ```
+//!
+//! # Distributed Scanning

+//! FormPost Support for Swift API
+//!
+//! This module implements HTML form-based file uploads to Swift containers
+//! without requiring authentication. FormPost uses HMAC-SHA1 signatures to
+//! validate that forms were generated by an authorized user.
+//!
+//! # Overview
+//!
+//! FormPost allows users to upload files from HTML forms directly to Swift
+//! without exposing authentication credentials to the browser. The container
+//! owner generates a signed form with embedded signature, and browsers can
+//! POST files to that form.
+//!
+//! # Configuration
+//!
+//! FormPost uses the same TempURL key mechanism:
+//!
+//! ```bash
+//! # Set TempURL key for account
+//! swift post -m "Temp-URL-Key:mykey"
+//! ```
+//!
+//! # Form Fields
+//!
+//! Required fields:
+//! - `redirect` - URL to redirect to on success
+//! - `max_file_size` - Maximum size per file (bytes)
+//! - `max_file_count` - Maximum number of files
+//! - `expires` - Unix timestamp when form expires
+//! - `signature` - HMAC-SHA1 signature of form parameters
+//!
+//! Optional fields:
+//! - `redirect_error` - URL to redirect to on error (default: redirect)
+//!
+//! File fields:
+//! - `file` or `file1`, `file2`, etc. - Files to upload
+//!
+//! # Signature Generation
+//!
+//! ```text
+//! HMAC-SHA1(key, "{path}\n{redirect}\n{max_file_size}\n{max_file_count}\n{expires}")
+//! ```
+//!
+//! # Example HTML Form
+//!
+//! ```html
+//! <form action="http://swift.example.com/v1/AUTH_account/container"
+//!       method="POST" enctype="multipart/form-data">
+//!   <input type="hidden" name="redirect" value="https://example.com/success" />
+//!   <input type="hidden" name="max_file_size" value="10485760" />
+//!   <input type="hidden" name="max_file_count" value="5" />
+//!   <input type="hidden" name="expires" value="1640000000" />
+//!   <input type="hidden" name="signature" value="abcdef1234567890" />
+//!   <input type="file" name="file1" />
+//!   <input type="file" name="file2" />
+//!   <input type="submit" value="Upload" />
+//! </form>
+//! ```
+//!
+//! # Response
+//!
+//! On success: 303 See Other redirect to `redirect` URL with query params:
+//! - `?status=201&message=Created`
+//!
+//! On error: 303 See Other redirect to `redirect_error` URL (or `redirect`) with:
+//! - `?status=400&message=Error+description`

+//! OpenStack Swift API implementation
+//!
+//! This module provides support for the OpenStack Swift object storage API,
+//! enabling RustFS to serve as a Swift-compatible storage backend while
+//! reusing the existing S3 storage layer.
+//!
+//! # Architecture
+//!
+//! Swift requests follow the pattern: `/v1/{account}/{container}/{object}`
+//! where:
+//! - `account`: Tenant identifier (e.g., `AUTH_{project_id}`)
+//! - `container`: Swift container (maps to S3 bucket)
+//! - `object`: Object key (maps to S3 object key)
+//!
+//! # Authentication
+//!
+//! Swift API uses Keystone token-based authentication via the existing
+//! `KeystoneAuthMiddleware`. The middleware validates X-Auth-Token headers
+//! and stores credentials in task-local storage, which Swift handlers access
+//! to enforce tenant isolation.

+//! Container Quota Support for Swift API
+//!
+//! This module implements container quotas that limit the size and/or number
+//! of objects that can be stored in a container. Quotas are enforced during
+//! PUT operations and reject uploads that would exceed configured limits.
+//!
+//! # Configuration
+//!
+//! Quotas are configured via container metadata:
+//!
+//! - `X-Container-Meta-Quota-Bytes`: Maximum total bytes allowed in container
+//! - `X-Container-Meta-Quota-Count`: Maximum number of objects allowed in container
+//!
+//! # Usage
+//!
+//! ```bash
+//! # Set byte quota (10 GB)
+//! swift post my-container -H "X-Container-Meta-Quota-Bytes: 10737418240"
+//!
+//! # Set object count quota (1000 objects)
+//! swift post my-container -H "X-Container-Meta-Quota-Count: 1000"
+//!
+//! # Set both quotas
+//! swift post my-container \
+//!   -H "X-Container-Meta-Quota-Bytes: 10737418240" \
+//!   -H "X-Container-Meta-Quota-Count: 1000"
+//!
+//! # Remove quotas
+//! swift post my-container \
+//!   -H "X-Remove-Container-Meta-Quota-Bytes:" \
+//!   -H "X-Remove-Container-Meta-Quota-Count:"
+//! ```
+//!
+//! # Enforcement
+//!
+//! When a PUT request would cause the container to exceed its quota:
+//! - Request is rejected with 413 Payload Too Large
+//! - Response includes quota headers showing current usage
+//! - Object is not uploaded
+//!
+//! # Example
+//!
+//! ```bash
+//! # Container has quota of 1GB
+//! swift post my-container -H "X-Container-Meta-Quota-Bytes: 1073741824"
+//!
+//! # Current usage: 900MB, uploading 200MB file
+//! swift upload my-container large-file.bin
+//!
+//! # Response: 413 Payload Too Large
+//! # X-Container-Meta-Quota-Bytes: 1073741824
+//! # X-Container-Bytes-Used: 943718400
+//! ```

+//! Rate Limiting Support for Swift API
+//!
+//! This module implements rate limiting to prevent abuse and ensure fair resource
+//! allocation across tenants. Rate limits can be applied per-account, per-container,
+//! or per-IP address.
+//!
+//! # Configuration
+//!
+//! Rate limits are configured via container metadata:
+//!
+//! ```bash
+//! # Set account-level rate limit: 1000 requests per minute
+//! swift post -m "X-Account-Meta-Rate-Limit:1000/60"
+//!
+//! # Set container-level rate limit: 100 requests per minute
+//! swift post container -m "X-Container-Meta-Rate-Limit:100/60"
+//! ```
+//!
+//! # Response Headers
+//!
+//! Rate limit information is included in all responses:
+//!
+//! ```http
+//! HTTP/1.1 200 OK
+//! X-RateLimit-Limit: 1000
+//! X-RateLimit-Remaining: 950
+//! X-RateLimit-Reset: 1740003600
+//! ```
+//!
+//! When rate limit is exceeded:
+//!
+//! ```http
+//! HTTP/1.1 429 Too Many Requests
+//! X-RateLimit-Limit: 1000
+//! X-RateLimit-Remaining: 0
+//! X-RateLimit-Reset: 1740003600
+//! Retry-After: 30
+//! ```
+//!
+//! # Algorithm
+//!
+//! Uses token bucket algorithm with per-second refill rate:
+//! - Each request consumes 1 token
+//! - Tokens refill at configured rate
+//! - Burst capacity allows temporary spikes

+
+//! Static Website Hosting for Swift Containers
+//!
+//! This module implements static website hosting, allowing Swift containers
+//! to serve static websites directly without requiring an external web server.
+//!
+//! # Features
+//!
+//! - **Index Documents**: Serve default index.html for directory requests
+//! - **Error Documents**: Custom 404 error pages
+//! - **Directory Listings**: Auto-generated HTML listings (optional)
+//! - **Custom CSS**: Style directory listings with custom CSS
+//!
+//! # Configuration
+//!
+//! Static website hosting is configured via container metadata:
+//!
+//! - `X-Container-Meta-Web-Index` - Index document name (e.g., "index.html")
+//! - `X-Container-Meta-Web-Error` - Error document name (e.g., "404.html")
+//! - `X-Container-Meta-Web-Listings` - Enable directory listings ("true"/"false")
+//! - `X-Container-Meta-Web-Listings-CSS` - CSS file path for listings styling
+//!
+//! # Examples
+//!
+//! ```bash
+//! # Enable static website hosting
+//! swift post my-website \
+//!   -m "web-index:index.html" \
+//!   -m "web-error:404.html" \
+//!   -m "web-listings:true"
+//!
+//! # Upload website files
+//! swift upload my-website index.html
+//! swift upload my-website 404.html
+//! swift upload my-website style.css
+//!
+//! # Access website
+//! curl http://swift.example.com/v1/AUTH_account/my-website/
+//! # Returns: index.html
+//! ```
+//!
+//! # Path Resolution
+//!
+//! 1. **Root or directory path** (ends with `/`):
+//!    - Serve index document if configured
+//!    - Otherwise, generate directory listing if enabled
+//!    - Otherwise, return 404
+//!
+//! 2. **File path**:
+//!    - Serve the file if it exists
+//!    - If not found and error document configured, serve error document
+//!    - Otherwise, return standard 404
+//!
+//! 3. **Directory without trailing slash**:
+//!    - Redirect to path with trailing slash (301)

+//! Object Symlinks Support for Swift API
+//!
+//! This module implements symlink objects that reference other objects,
+//! similar to filesystem symlinks. Symlinks allow creating multiple references
+//! to the same object without duplicating data.
+//!
+//! # Configuration
+//!
+//! Symlinks are created via the X-Object-Symlink-Target header:
+//!
+//! ```bash
+//! # Create symlink to object in same container
+//! curl -X PUT "http://swift.example.com/v1/AUTH_test/container/link" \
+//!   -H "X-Auth-Token: $TOKEN" \
+//!   -H "X-Object-Symlink-Target: object.txt"
+//!
+//! # Create symlink to object in different container
+//! curl -X PUT "http://swift.example.com/v1/AUTH_test/container/link" \
+//!   -H "X-Auth-Token: $TOKEN" \
+//!   -H "X-Object-Symlink-Target: other-container/object.txt"
+//! ```
+//!
+//! # Symlink Resolution
+//!
+//! When a GET or HEAD request is made on a symlink:
+//! 1. The symlink target is extracted from metadata
+//! 2. The target object is retrieved (following symlink chain if needed)
+//! 3. Target object content is returned with X-Symlink-Target header
+//! 4. Loop detection prevents infinite recursion (max 5 hops)
+//!
+//! # Example Usage
+//!
+//! ```bash
+//! # Upload original object
+//! swift upload container file.txt
+//!
+//! # Create symlink
+//! swift upload container link.txt \
+//!   -H "X-Object-Symlink-Target: file.txt" \
+//!   --object-name link.txt
+//!
+//! # Download via symlink (returns file.txt content)
+//! swift download container link.txt
+//! # Response includes: X-Symlink-Target: container/file.txt
+//! ```

+//! Container Synchronization Support for Swift API
+//!
+//! This module implements bidirectional container synchronization between
+//! Swift clusters, enabling disaster recovery, geo-replication, and
+//! multi-region deployments.
+//!
+//! # Configuration
+//!
+//! Container sync is configured via container metadata:
+//!
+//! ```bash
+//! # Set sync target and key
+//! swift post my-container \
+//!   -H "X-Container-Sync-To: https://remote-swift.example.com/v1/AUTH_remote/backup-container" \
+//!   -H "X-Container-Sync-Key: mysecretkey123"
+//! ```
+//!
+//! # Sync Process
+//!
+//! 1. Background worker periodically scans containers with sync configuration
+//! 2. Compares local objects with remote container
+//! 3. Syncs new/updated objects to remote
+//! 4. Uses timestamp-based conflict resolution
+//! 5. Retries failed syncs with exponential backoff
+//!
+//! # Conflict Resolution
+//!
+//! - **Last-Write-Wins**: Most recent timestamp wins
+//! - **Bidirectional**: Both clusters can accept writes
+//! - **Eventual Consistency**: Objects converge to same state
+//!
+//! # Security
+//!
+//! - Shared secret key (X-Container-Sync-Key) for authentication
+//! - HTTPS recommended for remote connections
+//! - Per-container isolation
+

+//! Object Versioning Support for Swift API
+//!
+//! Implements Swift object versioning where old versions are automatically
+//! archived when objects are overwritten or deleted.
+//!
+//! # Architecture
+//!
+//! - **Version-enabled container**: Primary container holding current objects
+//! - **Archive container**: Separate container storing old versions
+//! - **Version naming**: `{inverted_timestamp}/{container}/{object}`
+//!
+//! # Version Naming Convention
+//!
+//! Versions are stored with inverted timestamps so newer versions sort first:
+//! ```text
+//! Original: /v1/AUTH_test/photos/cat.jpg
+//! Version 1: /v1/AUTH_test/archive/9999999999.999999999/photos/cat.jpg
+//! Version 2: /v1/AUTH_test/archive/9999999999.999999998/photos/cat.jpg
+//! ```
+//!
+//! The timestamp is calculated as: `9999999999.999999999 - current_timestamp`
+//!
+//! Timestamps use 9 decimal places (nanosecond precision) to prevent collisions
+//! in high-throughput scenarios where multiple versions are created rapidly.
+//!
+//! # Versioning Flow
+//!
+//! ## On PUT (overwrite):
+//! 1. Check if container has versioning enabled
+//! 2. If object exists, copy it to archive with versioned name
+//! 3. Proceed with normal PUT operation
+//!
+//! ## On DELETE:
+//! 1. Check if container has versioning enabled
+//! 2. Delete current object
+//! 3. List versions in archive (newest first)
+//! 4. If versions exist, restore newest to current container
+//! 5. Delete restored version from archive
