feat: add Moltbot Secure edition for Railway deployment

A lean, secure, self-hosted AI assistant designed for Railway:

- Telegram-only channel (allowlist-based access control)
- Authenticated webhook receiver for external integrations
- Docker sandbox for isolated code execution
- Cron scheduler for recurring tasks
- Env-only configuration (no config files)
- Full audit logging

Core files:
- secure/config.ts - Environment-only configuration
- secure/audit.ts - Audit logging system
- secure/agent.ts - AI agent core (Anthropic/OpenAI)
- secure/telegram.ts - Telegram bot handler
- secure/webhooks.ts - Webhook receiver
- secure/sandbox.ts - Docker sandbox execution
- secure/scheduler.ts - Cron task scheduler
- secure/index.ts - Main entry point
- secure/Dockerfile - Minimal container image
- secure/railway.json - Railway deployment config

# Moltbot Secure Edition
A lean, secure, self-hosted AI assistant for Railway deployment.
## Philosophy
**Your AI agent that runs on your infrastructure, answers only to you, and you can actually audit.**
- No SaaS middleman
- No data harvesting
- Your keys, your server, your rules
## Core Principles
| Principle | Implementation |
|-----------|----------------|
| **Allowlist-only** | Nobody talks to it unless explicitly approved |
| **Env-var config** | No config files to leak, no filesystem secrets |
| **Audit log** | Every interaction logged, inspectable |
| **No phone-home** | Zero telemetry, no central service |
| **Minimal surface** | Small codebase, few deps, easy to read |
| **Your keys** | Direct to Anthropic/OpenAI, no proxy |
## Architecture

```
## Features
### Telegram (Primary UI)
- Chat with AI (text, voice transcription, images)
- Forward anything for analysis
- Upload docs for Q&A
- `/commands` for quick actions
- **Allowlist-only**: Must be in `ALLOWED_USERS`
### Webhooks (Inbound)
- Authenticated endpoint at `/hooks/*`
- Receive from GitHub, Stripe, uptime monitors, etc.
- AI summarizes and forwards to Telegram
- Bearer token or `X-Moltbot-Token` header auth
### Scheduler (Cron)
- Built-in cron expressions
- Morning briefings, monitors, recurring tasks
- `at:` one-shot scheduling
- `every:` interval scheduling
### Sandbox (Isolated Execution)
- Docker container for code/script execution
- Network isolated by default
- Resource limits (CPU, memory, time)
- Read-only root filesystem
- Ephemeral - destroyed after use
## Configuration
All configuration via environment variables. No config files.
### Required
```bash
# Bot Identity
TELEGRAM_BOT_TOKEN=123456:ABC-DEF...
# AI Provider (pick one)
ANTHROPIC_API_KEY=sk-ant-...
# or
OPENAI_API_KEY=sk-...
# Access Control
ALLOWED_USERS=123456789,987654321 # Telegram user IDs
```
### Optional
```bash
# Webhook Authentication
WEBHOOK_SECRET=your-random-32-char-secret
# Gateway Auth (for internal API)
MOLTBOT_GATEWAY_TOKEN=another-random-secret
# Sandbox Settings
SANDBOX_ENABLED=true
SANDBOX_NETWORK=none # none | bridge
SANDBOX_MEMORY=512m
SANDBOX_CPUS=1
# Audit Logging
AUDIT_LOG_PATH=/data/audit.jsonl
```
## Railway Deployment
### One-Click Deploy
[![Deploy on Railway](https://railway.app/button.svg)](https://railway.app/template/moltbot-secure)
### Manual Setup
1. Create new Railway project
2. Add from GitHub repo
3. Set environment variables:
- `TELEGRAM_BOT_TOKEN`
- `ANTHROPIC_API_KEY` or `OPENAI_API_KEY`
- `ALLOWED_USERS`
- `WEBHOOK_SECRET` (recommended)
4. Add volume at `/data` for persistence
5. Deploy
### railway.json
```json
{
"$schema": "https://railway.app/railway.schema.json",
"build": {
"builder": "DOCKERFILE",
"dockerfilePath": "Dockerfile.secure"
},
"deploy": {
"healthcheckPath": "/health",
"healthcheckTimeout": 30,
"restartPolicyType": "ON_FAILURE",
"restartPolicyMaxRetries": 3
}
}
```
## Security Model
### What We Block
- **Unauthorized users**: Only `ALLOWED_USERS` can interact
- **Unauthenticated webhooks**: Require valid token
- **Network in sandbox**: Disabled by default
- **Filesystem access**: Read-only root, tmpfs only
- **Privilege escalation**: All caps dropped
- **Secret leakage**: Automatic redaction in logs
### What We Log
Every interaction is logged to `AUDIT_LOG_PATH`:
```jsonl
{"ts":"2024-01-15T10:30:00Z","type":"message","user":123456789,"text":"...","response":"..."}
{"ts":"2024-01-15T10:30:05Z","type":"webhook","path":"/hooks/github","status":200}
{"ts":"2024-01-15T10:30:10Z","type":"sandbox","command":"python script.py","exit":0}
```
### Threat Model
| Threat | Mitigation |
|--------|------------|
| Unauthorized access | Telegram user ID allowlist |
| Webhook abuse | Bearer token auth, rate limits |
| Code execution escape | Docker isolation, no network, caps dropped |
| Secret exposure | Env-only config, log redaction |
| Model prompt injection | Sandboxed tool execution |
## What's NOT Included
Intentionally removed for security/simplicity:
- Web UI / Setup wizard
- WebSocket device pairing
- Plugin/extension system
- WhatsApp/Signal/iMessage/Discord
- Multi-account support
- Browser automation sandbox
- File-based configuration
## Development
```bash
# Install dependencies
pnpm install
# Run in dev mode
TELEGRAM_BOT_TOKEN=xxx ANTHROPIC_API_KEY=xxx ALLOWED_USERS=123 pnpm dev:secure
# Build
pnpm build:secure
# Test
pnpm test:secure
```
## Directory Structure (Secure Edition)
```

├── index.ts # Entry point
├── config.ts # Env-only config loader

├── webhooks.ts # Webhook receiver
