Thank you for beta-testing **Reponoesis (rpn)**! This release is packaged locally and securely to keep our proprietary semantic engine private.

---

## 🛠️ Prerequisites
- **Node.js**: Version 20.0.0 or higher
- **IDE**: Cursor or Claude Code (if using MCP server)

---

## 📦 Step 1: Installation
Open your terminal in the directory where you saved these files and run:

\`\`\`bash
# 1. Install CLI globally
npm install -g ./${cliTarball}

# 2. Install MCP Server globally
npm install -g ./${mcpTarball}
\`\`\`

*Note: Node will automatically download safe standard public dependencies (like \`better-sqlite3\` and \`simple-git\`) from the public npm registry. Our core semantic Merkle engine runs privately from the local bundle.*

Verify the installations:
\`\`\`bash
rpn --version
rpn-mcp --help
\`\`\`

---

## 🚀 Step 2: Initialize in Your Codebase
Navigate to any git repository on your laptop:

\`\`\`bash
# 1. Initialize
rpn init

# 2. Run a full scan (indexes codebases offline in SQLite)
rpn scan

# 3. Check health status
rpn status
\`\`\`

---

## 🧠 Step 3: Link Cursor or Claude Code as the AI Brain (Zero LLM Cost)
To make your AI agent automatically align configurations, document WHY changes were made, and prevent semantic drift:

1. Open **Cursor Settings** → **Models** → **MCP**.
2. Click **+ Add New MCP Server**.
3. Fill in the details:
   - **Name**: \`reponoesis\`
   - **Type**: \`command\`
   - **Command**: \`rpn-mcp\`
   - **Arguments**: \`["--project", "/absolute/path/to/your/project"]\`
4. Click **Save**.

Your AI agent now has first-class access to 7 powerful tools (\`rpn_get_context\`, \`rpn_impact_map\`, \`rpn_validate\`, etc.) to secure code limits, API versions, and schema parameters for free!
