+# Changelog
+
+## 2026-02-13 - 5.1.1 - fix(smarts3)
+replace TypeScript server with Rust-powered core and IPC bridge
+
+- Major refactor: Node.js/TypeScript in-process server replaced by a Rust crate ('rusts3') with a TypeScript IPC wrapper (RustBridge).
+- Removed many TypeScript server modules (smarts3-server, filesystem-store, multipart-manager, controllers, router, context, logger, xml utils, etc.); Smarts3Server export removed — public API now proxies to the Rust binary.
+- Smarts3 now spawns and communicates with the rusts3 binary via RustBridge IPC (commands include start, stop, createBucket).
+- Build & packaging changes: build script now runs `tsrust` before `tsbuild`; added `@git.zone/tsrust` devDependency; added `dist_rust` artifacts and new cross-compile targets in npmextra.json; .gitignore updated for rust/target.
+- Dependency changes: added `@push.rocks/smartrust` (RustBridge) and simplified plugins surface; previous smartfs/smartxml usage removed from TS code and replaced by the Rust implementation + IPC.
+- Added Rust project files (rust/Cargo.toml, rust/src/*) implementing server, IPC management loop, storage, XML responses, errors, and config.
+- Documentation updated (README and hints) to describe the Rust core, supported prebuilt targets (linux_amd64, linux_arm64), IPC commands, and developer build notes.
+
+## 2025-11-23 - 5.1.0 - feat(multipart)
+Implement full multipart upload support with persistent manager, periodic cleanup, and API integration
+
+- Add IMultipartConfig to server config with defaults (expirationDays: 7, cleanupIntervalMinutes: 60) and merge into existing config flow
+- Introduce MultipartUploadManager: persistent upload metadata on disk, part upload/assembly, restore uploads on startup, listParts/listUploads, abort/cleanup functionality
+- Start and stop multipart cleanup task from Smarts3Server lifecycle (startCleanupTask on start, stopCleanupTask on stop) with configurable interval and expiration
+- ObjectController: support multipart endpoints (initiate, upload part, complete, abort) and move assembled final object into the object store on completion; set ETag headers and return proper XML responses
+- BucketController: support listing in-progress multipart uploads via ?uploads query parameter and return S3-compatible XML
+- Persist multipart state to disk and restore on initialization to survive restarts; perform automatic cleanup of expired uploads
+
+## 2025-11-23 - 5.0.2 - fix(readme)
+Clarify contribution agreement requirement in README
+
+- Updated the Issue Reporting and Security section in readme.md to make it explicit that developers must sign and comply with the contribution agreement (and complete identification) before obtaining a code.foss.global account to submit pull requests.
+
+## 2025-11-23 - 5.0.1 - fix(docs)
+Clarify README wording about S3 compatibility and AWS SDK usage
+
+- Update README wording to "Full S3 API compatibility" and clarify it works seamlessly with AWS SDK v3 and other S3 clients
+
+## 2025-11-23 - 5.0.0 - BREAKING CHANGE(core)
+Production-ready S3-compatible server: nested config, multipart uploads, CORS, structured logging, SmartFS migration and improved error handling
+
+- Breaking change: configuration format migrated from flat to nested structure (server, storage, auth, cors, logging, limits). Update existing configs accordingly.
+- Implemented full multipart upload support (initiate, upload part, complete, abort) with on-disk part management and final assembly.
+- Added CORS middleware with configurable origins, methods, headers, exposed headers, maxAge and credentials support.
+- Structured, configurable logging (levels: error|warn|info|debug; formats: text|json) and request/response logging middleware.
+- Simple static credential authentication middleware (configurable list of credentials).
+- Migrated filesystem operations to @push.rocks/smartfs (Web Streams interoperability) and removed smartbucket from production dependencies.
+- Improved S3-compatible error handling and XML responses (S3Error class and XML utilities).
+- Exposed Smarts3Server and made store/multipart managers accessible for tests and advanced usage; added helper methods like getS3Descriptor and createBucket.
+
+## 2025-11-23 - 4.0.0 - BREAKING CHANGE(Smarts3)
+Migrate Smarts3 configuration to nested server/storage objects and remove legacy flat config support
+
+- Smarts3.createAndStart() and Smarts3 constructor now accept ISmarts3Config with nested `server` and `storage` objects.
+- Removed support for the legacy flat config shape (top-level `port` and `cleanSlate`) / ILegacySmarts3Config.
+- Updated tests to use new config shape (server:{ port, silent } and storage:{ cleanSlate }).
+- mergeConfig and Smarts3Server now rely on the nested config shape; consumers must update their initialization code.
+
+## 2025-11-23 - 3.2.0 - feat(multipart)
+Add multipart upload support with MultipartUploadManager and controller integration
+
+- Introduce MultipartUploadManager (ts/classes/multipart-manager.ts) to manage multipart upload lifecycle and store parts on disk
+- Wire multipart manager into server and request context (S3Context, Smarts3Server) and initialize multipart storage on server start
+- Add multipart-related routes and handlers in ObjectController: initiate (POST ?uploads), upload part (PUT ?partNumber&uploadId), complete (POST ?uploadId), and abort (DELETE ?uploadId)
+- On complete, combine parts into final object and store via existing FilesystemStore workflow
+- Expose multipart manager on Smarts3Server for controller access
+
+## 2025-11-23 - 3.1.0 - feat(logging)
+Add structured Logger and integrate into Smarts3Server; pass full config to server
+
+- Introduce a new Logger class (ts/classes/logger.ts) providing leveled logging (error, warn, info, debug), text/json formats and an enable flag.
+- Integrate Logger into Smarts3Server: use structured logging for server lifecycle events, HTTP request/response logging and S3 errors instead of direct console usage.
+- Smarts3 now passes the full merged configuration into Smarts3Server (config.logging can control logging behavior).
+- Server start/stop messages and internal request/error logs are emitted via the Logger and respect the configured logging level/format and silent option.
+
+## 2025-11-23 - 3.0.4 - fix(smarts3)
+Use filesystem store for bucket creation and remove smartbucket runtime dependency
+
+- Switched createBucket to call the internal FilesystemStore.createBucket instead of using @push.rocks/smartbucket
+- Made Smarts3Server.store public so Smarts3 can access the filesystem store directly
+- Removed runtime import/export of @push.rocks/smartbucket from plugins and moved @push.rocks/smartbucket to devDependencies in package.json
+- Updated createBucket to return a simple { name } object after creating the bucket via the filesystem store
+
+## 2025-11-23 - 3.0.3 - fix(filesystem)
+Migrate filesystem implementation to @push.rocks/smartfs and add Web Streams handling
+
+- Replace dependency @push.rocks/smartfile with @push.rocks/smartfs and update README references
+- plugins: instantiate SmartFs with SmartFsProviderNode and export smartfs (remove direct fs export)
+- Refactor FilesystemStore to use smartfs directory/file APIs for initialize, reset, list, read, write, copy and delete
+- Implement Web Stream ↔ Node.js stream conversion for uploads/downloads (Readable.fromWeb and writer.write with Uint8Array)
+- Persist and read metadata (.metadata.json) and cached MD5 (.md5) via smartfs APIs
+- Update readme.hints and documentation to note successful migration and next steps
+
+## 2025-11-21 - 3.0.2 - fix(smarts3)
+Prepare patch release 3.0.2 — no code changes detected
+
+- No source changes in the diff
+- Bump patch version from 3.0.1 to 3.0.2 for maintenance/release bookkeeping
+
+## 2025-11-21 - 3.0.1 - fix(readme)
+Add Issue Reporting and Security section to README
+
+- Add guidance to report bugs, issues, and security vulnerabilities via community.foss.global
+- Inform developers how to sign a contribution agreement and get a code.foss.global account to submit pull requests
+
+## 2025-11-21 - 3.0.0 - BREAKING CHANGE(Smarts3)
+Remove legacy s3rver backend, simplify Smarts3 server API, and bump dependencies
+
+- Remove legacy s3rver backend: s3rver and its types were removed from dependencies and are no longer exported from plugins.
+- Simplify Smarts3 API: removed useCustomServer option; Smarts3 now always uses the built-in Smarts3Server (s3Instance is Smarts3Server) and stop() always calls Smarts3Server.stop().
+- Update README to remove legacy s3rver compatibility mention.
+- Dependency updates: bumped @push.rocks/smartbucket to ^4.3.0 and @push.rocks/smartxml to ^2.0.0 (major upgrades), removed s3rver/@types/s3rver, bumped @aws-sdk/client-s3 to ^3.937.0 and @git.zone/tstest to ^3.1.0.
+
+## 2025-11-21 - 2.3.0 - feat(smarts3-server)
+Introduce native custom S3 server implementation (Smarts3Server) with routing, middleware, context, filesystem store, controllers and XML utilities; add SmartXml and AWS SDK test; keep optional legacy s3rver backend.
+
+- Add Smarts3Server: native, Node.js http-based S3-compatible server (ts/classes/smarts3-server.ts)
+- New routing and middleware system: S3Router and MiddlewareStack for pattern matching and middleware composition (ts/classes/router.ts, ts/classes/middleware-stack.ts)
+- Introduce request context and helpers: S3Context for parsing requests, sending responses and XML (ts/classes/context.ts)
+- Filesystem-backed storage: FilesystemStore with bucket/object operations, streaming uploads, MD5 handling and Windows-safe key encoding (ts/classes/filesystem-store.ts)
+- S3 error handling: S3Error class that maps S3 error codes and produces XML error responses (ts/classes/s3-error.ts)
+- Controllers for service, bucket and object operations with S3-compatible XML responses and copy/range support (ts/controllers/*.ts)
+- XML utilities and SmartXml integration for consistent XML generation/parsing (ts/utils/xml.utils.ts, ts/plugins.ts)
+- Expose native plugins (http, crypto, url, fs) and SmartXml via plugins.ts
+- ts/index.ts: add useCustomServer option, default to custom server, export Smarts3Server and handle start/stop for both custom and legacy backends
+- Add AWS SDK v3 integration test (test/test.aws-sdk.node.ts) to validate compatibility
+- package.json: add @aws-sdk/client-s3 devDependency and @push.rocks/smartxml dependency
+- Documentation: readme.md updated to describe native custom server and legacy s3rver compatibility
+
+## 2025-11-20 - 2.2.7 - fix(core)
+Update dependencies, code style and project config; add pnpm overrides and ignore AI folders
+
+- Bump devDependencies and runtime dependencies (@git.zone/*, @push.rocks/*, @tsclass/tsclass, s3rver) to newer compatible versions
+- Add pnpm.overrides entry to package.json and normalize repository URL format
+- Code style and formatting fixes in TypeScript sources (ts/index.ts, ts/00_commitinfo_data.ts): whitespace, trailing commas, parameter formatting and minor API-return typing preserved
+- tsconfig.json: simplify compiler options and compact exclude list
+- Update .gitignore to add AI-related folders (.claude/, .serena/) to avoid accidental commits
+- Documentation and changelog formatting tweaks (readme.md, changelog.md, npmextra.json) — whitespace/newline cleanups and expanded changelog entries
+
+## 2025-08-16 - 2.2.6 - fix(Smarts3)
+
+Allow overriding S3 descriptor; update dependencies, test config and documentation
+
+- ts/index.ts: getS3Descriptor now accepts an optional Partial<IS3Descriptor> to override defaults (backwards compatible)
+- package.json: updated devDependencies and runtime dependency versions (tstest, smartpath, tsclass, s3rver, etc.) and added packageManager field
+- package.json: expanded test script to run tstest with --web --verbose --logfile --timeout 60
+- test/test.ts: test instance port changed to 3333
+- readme.md: major rewrite and expansion of usage examples, API reference and guides
+- added project config files: .claude/settings.local.json and .serena/project.yml

+# Production-Readiness Plan for smarts3
+
+**Goal:** Make smarts3 production-ready as a MinIO alternative for use cases where:
+- Running MinIO is out of scope
+- You have a program written for S3 and want to use the local filesystem
+- You need a lightweight, zero-dependency S3-compatible server
+
+---
+
+## 🔍 Current State Analysis
+
+### ✅ What's Working
+
+- **Native S3 server** with zero framework dependencies
+- **Core S3 operations:** PUT, GET, HEAD, DELETE (objects & buckets)
+- **List buckets and objects** (V1 and V2 API)
+- **Object copy** with metadata handling
+- **Range requests** for partial downloads
+- **MD5 checksums** and ETag support
+- **Custom metadata** (x-amz-meta-*)
+- **Filesystem-backed storage** with Windows compatibility
+- **S3-compatible XML error responses**
+- **Middleware system** and routing
+- **AWS SDK v3 compatibility** (tested)
+
+### ❌ Production Gaps Identified
+
+---
+
+## 🎯 Critical Features (Required for Production)
+
+### 1. Multipart Upload Support 🚀 **HIGHEST PRIORITY**
+
+**Why:** Essential for uploading files >5MB efficiently. Without this, smarts3 can't handle real-world production workloads.
+
+**Implementation Required:**
+- `POST /:bucket/:key?uploads` - CreateMultipartUpload
+- `PUT /:bucket/:key?partNumber=X&uploadId=Y` - UploadPart
+- `POST /:bucket/:key?uploadId=X` - CompleteMultipartUpload
+- `DELETE /:bucket/:key?uploadId=X` - AbortMultipartUpload
+- `GET /:bucket/:key?uploadId=X` - ListParts
+- Multipart state management (temp storage for parts)
+- Part ETag tracking and validation
+- Automatic cleanup of abandoned uploads
+
+**Files to Create/Modify:**
+- `ts/controllers/multipart.controller.ts` (new)
+- `ts/classes/filesystem-store.ts` (add multipart methods)
+- `ts/classes/smarts3-server.ts` (add multipart routes)
+
+---
+
+### 2. Configurable Authentication 🔐
+
+**Why:** Currently hardcoded credentials ('S3RVER'/'S3RVER'). Production needs custom credentials.
+
+**Implementation Required:**
+- Support custom access keys and secrets via configuration
+- Implement AWS Signature V4 verification
+- Support multiple credential pairs (IAM-like users)
+- Optional: Disable authentication for local dev use
+
+**Configuration Example:**
+```typescript
+interface IAuthConfig {
+  enabled: boolean;
+  credentials: Array<{
+    accessKeyId: string;
+    secretAccessKey: string;
+  }>;
+  signatureVersion: 'v4' | 'none';
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/auth-middleware.ts` (new)
+- `ts/classes/signature-validator.ts` (new)
+- `ts/classes/smarts3-server.ts` (integrate auth middleware)
+- `ts/index.ts` (add auth config options)
+
+---
+
+### 3. CORS Support 🌐
+
+**Why:** Required for browser-based uploads and modern web apps.
+
+**Implementation Required:**
+- Add CORS middleware
+- Support preflight OPTIONS requests
+- Configurable CORS origins, methods, headers
+- Per-bucket CORS configuration (optional)
+
+**Configuration Example:**
+```typescript
+interface ICorsConfig {
+  enabled: boolean;
+  allowedOrigins: string[]; // ['*'] or ['https://example.com']
+  allowedMethods: string[]; // ['GET', 'POST', 'PUT', 'DELETE']
+  allowedHeaders: string[]; // ['*'] or specific headers
+  exposedHeaders: string[]; // ['ETag', 'x-amz-*']
+  maxAge: number; // 3600 (seconds)
+  allowCredentials: boolean;
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/cors-middleware.ts` (new)
+- `ts/classes/smarts3-server.ts` (integrate CORS middleware)
+- `ts/index.ts` (add CORS config options)
+
+---
+
+### 4. SSL/TLS Support 🔒
+
+**Why:** Production systems require encrypted connections.
+
+**Implementation Required:**
+- HTTPS server option with cert/key configuration
+- Auto-redirect HTTP to HTTPS (optional)
+- Support for self-signed certs in dev mode
+
+**Configuration Example:**
+```typescript
+interface ISslConfig {
+  enabled: boolean;
+  cert: string; // Path to certificate file or cert content
+  key: string; // Path to key file or key content
+  ca?: string; // Optional CA cert
+  redirectHttp?: boolean; // Redirect HTTP to HTTPS
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/smarts3-server.ts` (add HTTPS server creation)
+- `ts/index.ts` (add SSL config options)
+
+---
+
+### 5. Production Configuration System ⚙️
+
+**Why:** Production needs flexible configuration, not just constructor options.
+
+**Implementation Required:**
+- Support configuration file (JSON/YAML)
+- Environment variable support
+- Configuration validation
+- Sensible production defaults
+- Example configurations for common use cases
+
+**Configuration File Example (`smarts3.config.json`):**
+```json
+{
+  "server": {
+    "port": 3000,
+    "address": "0.0.0.0",
+    "ssl": {
+      "enabled": true,
+      "cert": "./certs/server.crt",
+      "key": "./certs/server.key"
+    }
+  },
+  "storage": {
+    "directory": "./s3-data",
+    "cleanSlate": false
+  },
+  "auth": {
+    "enabled": true,
+    "credentials": [
+      {
+        "accessKeyId": "AKIAIOSFODNN7EXAMPLE",
+        "secretAccessKey": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
+      }
+    ]
+  },
+  "cors": {
+    "enabled": true,
+    "allowedOrigins": ["*"],
+    "allowedMethods": ["GET", "POST", "PUT", "DELETE", "HEAD"],
+    "allowedHeaders": ["*"]
+  },
+  "limits": {
+    "maxObjectSize": 5368709120,
+    "maxMetadataSize": 2048,
+    "requestTimeout": 300000
+  },
+  "logging": {
+    "level": "info",
+    "format": "json",
+    "accessLog": {
+      "enabled": true,
+      "path": "./logs/access.log"
+    },
+    "errorLog": {
+      "enabled": true,
+      "path": "./logs/error.log"
+    }
+  }
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/config-loader.ts` (new)
+- `ts/classes/config-validator.ts` (new)
+- `ts/index.ts` (use config loader)
+- Create example config files in root
+
+---
+
+### 6. Production Logging 📝
+
+**Why:** Console logs aren't suitable for production monitoring.
+
+**Implementation Required:**
+- Structured logging (JSON format option)
+- Log levels (ERROR, WARN, INFO, DEBUG)
+- File rotation support
+- Access logs (S3 standard format)
+- Integration with logging library
+
+**Files to Create/Modify:**
+- `ts/classes/logger.ts` (new - use @push.rocks/smartlog?)
+- `ts/classes/access-logger-middleware.ts` (new)
+- `ts/classes/smarts3-server.ts` (replace console.log with logger)
+- All controller files (use structured logging)
+
+---
+
+## 🔧 Important Features (Should Have)
+
+### 7. Health Check & Metrics 💊
+
+**Implementation Required:**
+- `GET /_health` endpoint (non-S3, for monitoring)
+- `GET /_metrics` endpoint (Prometheus format?)
+- Server stats (requests/sec, storage used, uptime)
+- Readiness/liveness probes for Kubernetes
+
+**Files to Create/Modify:**
+- `ts/controllers/health.controller.ts` (new)
+- `ts/classes/metrics-collector.ts` (new)
+- `ts/classes/smarts3-server.ts` (add health routes)
+
+---
+
+### 8. Batch Operations 📦
+
+**Implementation Required:**
+- `POST /:bucket?delete` - DeleteObjects (delete multiple objects in one request)
+- Essential for efficient cleanup operations
+
+**Files to Create/Modify:**
+- `ts/controllers/object.controller.ts` (add deleteObjects method)
+
+---
+
+### 9. Request Size Limits & Validation 🛡️
+
+**Implementation Required:**
+- Max object size configuration
+- Max metadata size limits
+- Request timeout configuration
+- Body size limits
+- Bucket name validation (S3 rules)
+- Key name validation
+
+**Files to Create/Modify:**
+- `ts/classes/validation-middleware.ts` (new)
+- `ts/utils/validators.ts` (new)
+- `ts/classes/smarts3-server.ts` (integrate validation middleware)
+
+---
+
+### 10. Conditional Requests 🔄
+
+**Implementation Required:**
+- If-Match / If-None-Match (ETag validation)
+- If-Modified-Since / If-Unmodified-Since
+- Required for caching and conflict prevention
+
+**Files to Create/Modify:**
+- `ts/controllers/object.controller.ts` (add conditional logic to GET/HEAD)
+
+---
+
+### 11. Graceful Shutdown 👋
+
+**Implementation Required:**
+- Drain existing connections
+- Reject new connections
+- Clean multipart cleanup on shutdown
+- SIGTERM/SIGINT handling
+
+**Files to Create/Modify:**

+
+## 🚀 Quick Start
+
+```typescript
+import { Smarts3 } from '@push.rocks/smarts3';
+
+// Start a local S3 server
+const s3 = await Smarts3.createAndStart({
+  server: { port: 3000 },
+  storage: { cleanSlate: true },
+});
+
+// Create a bucket
+await s3.createBucket('my-bucket');
+
+// Get connection details for any S3 client
+const descriptor = await s3.getS3Descriptor();
+// → { endpoint: 'localhost', port: 3000, accessKey: 'S3RVER', accessSecret: 'S3RVER', useSsl: false }
+
+// When done
+await s3.stop();
+```
+
+## 📖 Configuration
+
+All config fields are optional — sensible defaults are applied automatically.
+
+```typescript
+import { Smarts3, ISmarts3Config } from '@push.rocks/smarts3';
+
+const config: ISmarts3Config = {
+  server: {
+    port: 3000,              // Default: 3000
+    address: '0.0.0.0',      // Default: '0.0.0.0'
+    silent: false,           // Default: false
+  },
+  storage: {
+    directory: './my-data',  // Default: .nogit/bucketsDir
+    cleanSlate: false,       // Default: false — set true to wipe on start
+  },
+  auth: {
+    enabled: false,          // Default: false
+    credentials: [{
+      accessKeyId: 'MY_KEY',
+      secretAccessKey: 'MY_SECRET',
+    }],
+  },
+  cors: {
+    enabled: false,          // Default: false
+    allowedOrigins: ['*'],
+    allowedMethods: ['GET', 'POST', 'PUT', 'DELETE', 'HEAD', 'OPTIONS'],
+    allowedHeaders: ['*'],
+    exposedHeaders: ['ETag', 'x-amz-request-id', 'x-amz-version-id'],
+    maxAge: 86400,
+    allowCredentials: false,
+  },
+  logging: {
+    level: 'info',           // 'error' | 'warn' | 'info' | 'debug'
+    format: 'text',          // 'text' | 'json'
+    enabled: true,
+  },
+  limits: {
+    maxObjectSize: 5 * 1024 * 1024 * 1024, // 5 GB
+    maxMetadataSize: 2048,
+    requestTimeout: 300000,  // 5 minutes
+  },
+  multipart: {
+    expirationDays: 7,
+    cleanupIntervalMinutes: 60,
+  },
+};
+
+const s3 = await Smarts3.createAndStart(config);
+```
+
+### Common Configurations
+
+**CI/CD testing** — silent, clean, fast:
+```typescript
+const s3 = await Smarts3.createAndStart({
+  server: { port: 9999, silent: true },
+  storage: { cleanSlate: true },
+});
+```
+
+**Auth enabled:**
+```typescript
+const s3 = await Smarts3.createAndStart({
+  auth: {
+    enabled: true,
+    credentials: [{ accessKeyId: 'test', secretAccessKey: 'test123' }],
+  },
+});
+```
+
+**CORS for local web dev:**
+```typescript
+const s3 = await Smarts3.createAndStart({
+  cors: {
+    enabled: true,
+    allowedOrigins: ['http://localhost:5173'],
+    allowCredentials: true,
+  },
+});
+```
+
+## 📤 Usage with AWS SDK v3
+
+```typescript
+import { S3Client, PutObjectCommand, GetObjectCommand, DeleteObjectCommand } from '@aws-sdk/client-s3';
+
+const descriptor = await s3.getS3Descriptor();
+
+const client = new S3Client({
+  endpoint: `http://${descriptor.endpoint}:${descriptor.port}`,
+  region: 'us-east-1',
+  credentials: {
+    accessKeyId: descriptor.accessKey,
+    secretAccessKey: descriptor.accessSecret,
+  },
+  forcePathStyle: true,  // Required for path-style S3
+});
+
+// Upload
+await client.send(new PutObjectCommand({
+  Bucket: 'my-bucket',
+  Key: 'hello.txt',
+  Body: 'Hello, S3!',
+  ContentType: 'text/plain',
+}));
+
+// Download
+const { Body } = await client.send(new GetObjectCommand({
+  Bucket: 'my-bucket',
+  Key: 'hello.txt',
+}));
+const content = await Body.transformToString(); // "Hello, S3!"
+
+// Delete
+await client.send(new DeleteObjectCommand({
+  Bucket: 'my-bucket',
+  Key: 'hello.txt',
+}));
+```
+
+## 🪣 Usage with SmartBucket
+
+```typescript
+import { SmartBucket } from '@push.rocks/smartbucket';
+
+const smartbucket = new SmartBucket(await s3.getS3Descriptor());
+const bucket = await smartbucket.createBucket('my-bucket');
+const dir = await bucket.getBaseDirectory();
+
+// Upload
+await dir.fastPut({ path: 'docs/readme.txt', contents: 'Hello!' });
+
+// Download
+const content = await dir.fastGet('docs/readme.txt');
+
+// List
+const files = await dir.listFiles();
+```
+
+## 📤 Multipart Uploads
+
+For files larger than 5 MB, use multipart uploads. smarts3 handles them with **streaming I/O** — parts are written directly to disk, never buffered in memory.
+
+```typescript
+import {
+  CreateMultipartUploadCommand,
+  UploadPartCommand,
+  CompleteMultipartUploadCommand,
+} from '@aws-sdk/client-s3';
+
+// 1. Initiate
+const { UploadId } = await client.send(new CreateMultipartUploadCommand({
+  Bucket: 'my-bucket',
+  Key: 'large-file.bin',
+}));
+
+// 2. Upload parts
+const parts = [];
+for (let i = 0; i < chunks.length; i++) {
+  const { ETag } = await client.send(new UploadPartCommand({
+    Bucket: 'my-bucket',
+    Key: 'large-file.bin',
+    UploadId,
+    PartNumber: i + 1,
+    Body: chunks[i],
+  }));
+  parts.push({ PartNumber: i + 1, ETag });
+}
+
+// 3. Complete
+await client.send(new CompleteMultipartUploadCommand({
+  Bucket: 'my-bucket',
+  Key: 'large-file.bin',
+  UploadId,
+  MultipartUpload: { Parts: parts },
+}));
+```
+
+## 🧪 Testing Integration
+
+```typescript
+import { Smarts3 } from '@push.rocks/smarts3';
+import { tap, expect } from '@git.zone/tstest/tapbundle';
+
+let s3: Smarts3;
+
+tap.test('setup', async () => {
+  s3 = await Smarts3.createAndStart({
+    server: { port: 4567, silent: true },
+    storage: { cleanSlate: true },
+  });
+});
+
+tap.test('should store and retrieve objects', async () => {
+  await s3.createBucket('test');
+  // ... your test logic using AWS SDK or SmartBucket
+});
+
+tap.test('teardown', async () => {
+  await s3.stop();
+});
+
+export default tap.start();
+```
+

+| `accessSecret` | `string` | Secret key from first configured credential |
+| `useSsl` | `boolean` | Always `false` (plain HTTP) |
+
+## 🏗️ Architecture
+
+smarts3 uses a **hybrid Rust + TypeScript** architecture:
+
+```
+┌─────────────────────────────────┐
+│  Your Code (AWS SDK, etc.)      │
+│  ↕ HTTP (localhost:3000)        │
+├─────────────────────────────────┤
+│  rusts3 binary (Rust)           │
+│  ├─ hyper 1.x HTTP server      │
+│  ├─ S3 path-style routing      │
+│  ├─ Streaming storage layer    │
+│  ├─ Multipart manager          │
+│  ├─ CORS / Auth middleware     │
+│  └─ S3 XML response builder   │
+├─────────────────────────────────┤
+│  TypeScript (thin IPC wrapper)  │
+│  ├─ Smarts3 class              │
+│  ├─ RustBridge (stdin/stdout)  │
+│  └─ Config & S3 descriptor    │
+└─────────────────────────────────┘
+```
+
+**Why Rust?** The TypeScript implementation had critical perf issues: OOM on multipart uploads (parts buffered in memory), double stream copying, file descriptor leaks on HEAD requests, full-file reads for range requests, and no backpressure. The Rust binary solves all of these with streaming I/O, zero-copy, and direct `seek()` for range requests.
+
+**IPC Protocol:** TypeScript spawns the `rusts3` binary with `--management` and communicates via newline-delimited JSON over stdin/stdout. Commands: `start`, `stop`, `createBucket`.
+
+### S3 Operations Supported
+
+| Operation | Method | Path |
+|-----------|--------|------|
+| ListBuckets | `GET /` | |
+| CreateBucket | `PUT /{bucket}` | |
+| DeleteBucket | `DELETE /{bucket}` | |
+| HeadBucket | `HEAD /{bucket}` | |
+| ListObjects (v1/v2) | `GET /{bucket}` | `?list-type=2` for v2 |
+| PutObject | `PUT /{bucket}/{key}` | |
+| GetObject | `GET /{bucket}/{key}` | Supports `Range` header |
+| HeadObject | `HEAD /{bucket}/{key}` | |
+| DeleteObject | `DELETE /{bucket}/{key}` | |
+| CopyObject | `PUT /{bucket}/{key}` | `x-amz-copy-source` header |
+| InitiateMultipartUpload | `POST /{bucket}/{key}?uploads` | |
+| UploadPart | `PUT /{bucket}/{key}?partNumber&uploadId` | |
+| CompleteMultipartUpload | `POST /{bucket}/{key}?uploadId` | |
+| AbortMultipartUpload | `DELETE /{bucket}/{key}?uploadId` | |
+| ListMultipartUploads | `GET /{bucket}?uploads` | |
+
+### On-Disk Format
+
+```
+{storage.directory}/
+  {bucket}/
+    {key}._S3_object              # Object data
+    {key}._S3_object.metadata.json  # Metadata (content-type, x-amz-meta-*, etc.)
+    {key}._S3_object.md5          # Cached MD5 hash
+  .multipart/
+    {upload-id}/
+      metadata.json               # Upload metadata (bucket, key, parts)
+      part-1                      # Part data files
+      part-2
+      ...
