+C++20 port of [OpenClaw](https://openclaw.ai) — an AI gateway and CLI that connects AI models to messaging channels.
+
+This directory contains a faithful translation of the TypeScript source tree under `../src/` into standard C++20, maintaining the **same folder structure, file names, and public API surface** as the original.

+## Building
+
+### Prerequisites
+
+| Tool | Version |
+|------|---------|
+| CMake | ≥ 3.20 |
+| C++ compiler | GCC ≥ 12 / Clang ≥ 15 / MSVC 2022 |
+| ninja (optional) | any |
+
+The project vendors all dependencies as header-only libraries — no separate install step required.
+
+### Quick start
+
+```bash
+# From openclaw-cpp/
+cmake -B build -DCMAKE_BUILD_TYPE=Release
+cmake --build build -j$(nproc)
+./build/bin/openclaw --version
+```
+
+### Debug build with tests
+
+```bash
+cmake -B build -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTS=ON
+cmake --build build -j$(nproc)
+ctest --test-dir build --output-on-failure
+```
+
+---
+
+## Usage
+
+The CLI interface is identical to the TypeScript version:
+
+```bash
+openclaw --version
+openclaw --help
+openclaw agent --message "Hello"
+openclaw status
+openclaw config set gateway.mode local
+openclaw gateway run
+```
+
+---
+
+## Dependency Mapping
+
+| TypeScript (npm) | C++ equivalent |
+|-----------------|----------------|
+| `commander` | `CLI11` |
+| `zod` | Manual struct validation |
+| `pino` / `bunyan` | `spdlog` |
+| `node-fetch` / `axios` | `cpp-httplib` |
+| `ws` (WebSocket) | `cpp-httplib` WebSocket |
+| `JSON5` / `JSON.parse` | `nlohmann/json` |
+| `dotenv` | Custom `infra/dotenv.cpp` |
+| Node.js `fs` / `path` | `std::filesystem` |
+| Node.js `child_process` | `posix_spawn` / `CreateProcess` |
+| Node.js `net` / `http` | `cpp-httplib` |
+
+---
+
+## Architecture
+
+Each TypeScript module maps to a C++ translation unit:
+
+- `.ts` exports → `.hpp` public header + `.cpp` implementation
+- `*.test.ts` → `tests/` directory with matching name (e.g. `version.test.cpp`)
+- `index.ts` re-exports → `index.hpp` aggregating includes
+- Dynamic `import()` → lazy-loaded via function pointers / `std::function`
+- `process.env` → `std::getenv` wrapped in `infra/env.hpp`
+- `process.exit` → `std::exit` via `runtime.hpp` `RuntimeEnv`
+
+---
+
+## Status
+
+| Module | Status |
+|--------|--------|
+| `src/version` | ✅ Full |
+| `src/infra/env` | ✅ Full |
+| `src/infra/errors` | ✅ Full |
+| `src/infra/is-main` | ✅ Full |
+| `src/infra/ports` | ✅ Full |
+| `src/utils` | ✅ Full |
+| `src/globals` | ✅ Full |
+| `src/runtime` | ✅ Full |
+| `src/logger` | ✅ Full |
+| `src/logging` | ✅ Full |
+| `src/cli/argv` | ✅ Full |
+| `src/cli/program` | ✅ Full |
+| `src/entry` | ✅ Full |
+| `src/index` | ✅ Full |
+| `src/config/*` | ✅ Stub |
+| `src/commands/*` | ✅ Stub |
+| `src/acp/*` | ✅ Stub |
+| `src/agents/*` | ✅ Stub |
+| `src/channels/*` | ✅ Stub |
+| `src/gateway/*` | ✅ Stub |
+| `src/providers/*` | ✅ Stub |
+| All other modules | ✅ Stub |
+
+> **Stub** = header + minimal implementation skeleton with the same public API signature.
+> Full conversion of every module is in progress.
