+## Философия
+
+IronClaw построен на простом принципе: **ваш AI-ассистент должен работать на вас, а не против вас**.
+
+В мире, где системы ИИ становятся все более непрозрачными в вопросах обработки данных и ориентируются на корпоративные интересы, IronClaw выбирает другой путь:
+
+- **Ваши данные остаются вашими** — вся информация хранится локально, зашифрована и никогда не покидает ваш контроль.
+- **Прозрачность по умолчанию** — открытый исходный код, возможность аудита, отсутствие скрытой телеметрии или сбора данных.
+- **Саморасширяемые возможности** — создавайте новые инструменты «на лету», не дожидаясь обновлений от вендора.
+- **Глубокая защита** — несколько уровней безопасности защищают от инъекций промптов и утечки данных.
+
+IronClaw — это AI-ассистент, которому вы действительно можете доверять в личной и профессиональной жизни.
+
+## Возможности
+
+### Безопасность прежде всего
+
+- **Песочница WASM** — непроверенные инструменты запускаются в изолированных контейнерах WebAssembly с правами на основе возможностей.

+  <summary>Компиляция из исходного кода (Cargo на Windows, Linux, macOS)</summary>
+
+Для установки используйте `cargo`, предварительно убедившись, что у вас установлен [Rust](https://rustup.rs).
+
+```bash
+# Клонируйте репозиторий
+git clone https://github.com/nearai/ironclaw.git
+cd ironclaw
+
+# Сборка
+cargo build --release
+
+# Запуск тестов
+cargo test
+```
+
+Для **полного релиза** (после модификации исходников каналов) выполните `./scripts/build-all.sh`, чтобы сначала пересобрать каналы.
+
+</details>
+
+### Настройка базы данных
+
+```bash
+# Создание базы данных
+createdb ironclaw
+
+# Включение pgvector
+psql ironclaw -c "CREATE EXTENSION IF NOT EXISTS vector;"
+```
+
+## Конфигурация
+
+Запустите мастер настройки для конфигурации IronClaw:
+
+```bash
+ironclaw onboard
+```
+
+Мастер настройки поможет установить соединение с базой данных, пройти аутентификацию NEAR AI (через браузер OAuth) и настроить шифрование секретов (используя системную связку ключей). Настройки сохраняются в базе данных; базовые переменные (например, `DATABASE_URL`, `LLM_BACKEND`) записываются в `~/.ironclaw/.env`, чтобы они были доступны до подключения к БД.
+
+### Альтернативные LLM-провайдеры
+
+IronClaw по умолчанию использует NEAR AI, но работает с любыми OpenAI-совместимыми эндпоинтами.
+Популярные варианты включают **OpenRouter** (300+ моделей), **Together AI**, **Fireworks AI**, **Ollama** (локально) и собственные серверы, такие как **vLLM** или **LiteLLM**.
+
+Выберите *"OpenAI-compatible"* в мастере настройки или установите переменные окружения напрямую:
+
+```env
+LLM_BACKEND=openai_compatible
+LLM_BASE_URL=https://openrouter.ai/api/v1
+LLM_API_KEY=sk-or-...
+LLM_MODEL=anthropic/claude-sonnet-4
+```
+
+Смотрите [docs/LLM_PROVIDERS.md](docs/LLM_PROVIDERS.md) для получения полного руководства по провайдерам.
+
+## Безопасность
+
+IronClaw реализует эшелонированную защиту для обеспечения безопасности ваших данных и предотвращения злоупотреблений.
+
+### Песочница WASM
+
+Все непроверенные инструменты запускаются в изолированных контейнерах WebAssembly:
+
+- **Права на основе возможностей** — явное разрешение на HTTP, доступ к секретам, вызов инструментов.
+- **Список разрешенных эндпоинтов** — HTTP-запросы только к одобренным хостам/путям.
+- **Внедрение учетных данных** — секреты внедряются на границе хоста и никогда не раскрываются коду WASM.
+- **Детектирование утечек** — сканирование запросов и ответов на попытки кражи секретов.
+- **Ограничение частоты запросов** — лимиты для каждого инструмента для предотвращения злоупотреблений.
+- **Лимиты ресурсов** — ограничения по памяти, процессору и времени выполнения.
+
+```
+WASM ──► Валидатор ──► Сканер ───► Инъектор ──► Выполнение ──► Сканер ───► WASM
+         хостов        утечек      секретов      запроса        утечек
+                       (запрос)                                 (ответ)
+```
+
+### Защита от инъекций промптов
+
+Внешний контент проходит через несколько уровней безопасности:
+
+- Обнаружение попыток инъекций на основе паттернов.
+- Очистка и экранирование контента.
+- Правила политик с уровнями серьезности (Блокировка/Предупреждение/Проверка/Очистка).
+- Обертывание вывода инструментов для безопасного внедрения в контекст LLM.
+
+### Защита данных
+
+- Все данные хранятся локально в вашей базе данных PostgreSQL.
+- Секреты зашифрованы с использованием AES-256-GCM.
+- Никакой телеметрии, аналитики или обмена данными.
+- Полный журнал аудита выполнения всех инструментов.

+
+## Наследие OpenClaw
+
+IronClaw — это реализация на Rust, вдохновленная проектом [OpenClaw](https://github.com/openclaw/openclaw). Полную матрицу соответствия функций можно найти в [FEATURE_PARITY.md](FEATURE_PARITY.md).
+
+Ключевые отличия:
+
+- **Rust vs TypeScript** — нативная производительность, безопасность памяти, один бинарный файл.
+- **Песочница WASM vs Docker** — легковесность, безопасность на основе возможностей.
+- **PostgreSQL vs SQLite** — надежное хранилище, готовое к продакшну.
+- **Безопасность прежде всего** — многослойная защита, сохранность учетных данных.

+- `owner_id`: when set, only that Discord user can interact with the bot.

+# ironclaw_safety Fuzz Targets
+
+Fuzz testing for the `ironclaw_safety` crate using [cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz) (libFuzzer).
+
+## Targets
+
+| Target | What it exercises |
+|--------|-------------------|
+| `fuzz_safety_sanitizer` | Prompt injection pattern detection (Aho-Corasick + regex) |
+| `fuzz_safety_validator` | Input validation (length, encoding, forbidden patterns) |
+| `fuzz_leak_detector` | Secret leak detection (API keys, tokens, credentials) |
+| `fuzz_credential_detect` | HTTP request credential detection |
+| `fuzz_config_env` | SafetyLayer end-to-end (sanitize, validate, policy check) |
+
+## Setup
+
+```bash
+cargo install cargo-fuzz
+rustup install nightly
+```
+
+## Running
+
+```bash
+cd crates/ironclaw_safety
+
+# Run a specific target (runs until stopped or crash found)
+cargo +nightly fuzz run fuzz_safety_sanitizer
+
+# Run with a time limit (5 minutes)
+cargo +nightly fuzz run fuzz_leak_detector -- -max_total_time=300
+
+# Run all targets for 60 seconds each
+for target in fuzz_safety_sanitizer fuzz_safety_validator fuzz_leak_detector fuzz_credential_detect fuzz_config_env; do
+    echo "==> $target"
+    cargo +nightly fuzz run "$target" -- -max_total_time=60
+done
+```
+
+## Seed Corpus
+
+Each target has a seed corpus in `corpus/<target>/` with representative inputs covering the major pattern families. The fuzzer uses these as starting points for mutation.

 | `fuzz_tool_params` | Tool parameter and schema JSON validation |

+//! `enable`/`disable` require modifying channel configuration, but the config
+//! source is currently split: built-in channels (cli, http, gateway, signal)
+//! are resolved from environment variables in `ChannelsConfig::resolve()`,
+//! while `settings.channels.*` fields are not consumed by that path.
+//! Until `resolve()` falls back to settings (or the CLI writes `.env`),
+//! an `enable`/`disable` command would silently fail to take effect.
+//!
+//! `status` (runtime health) requires connecting to a running IronClaw instance
+//! via IPC or HTTP, which does not exist yet as a CLI control plane.

+"""Comprehensive WASM extension lifecycle e2e tests.
+
+Tests the full extension pipeline: registry → install → fields → configure →
+activate → tools → remove → reinstall. Validates response fields, not just
+status codes, to catch production bugs like missing capabilities, wrong
+activation state, and stale registry flags.
+
+Lifecycle stages are expressed as scoped fixtures so each test requests the
+state it needs explicitly rather than relying on module-global flags.
