## 📌 Overview & Capability

**genpark-immutable-double-entry-ledger-kernel-skill** is a deterministic, zero-dependency Python skill engineered with 100% production-grade functional parity for autonomous financial agents, real-time payment webhooks, immutable double-entry bookkeeping, and transaction fraud defense.

> **Executive Capability**: Cryptographic double-entry bookkeeping engine enforcing sum(Debits) == sum(Credits) invariants and hash-chained audit trails.

### ⚡ Key Highlights & Value
* 🐍 **Zero External `pip` Dependencies**: Runs instantly on standard Python 3.9+ using built-in `hmac`, `hashlib`, and pure financial algorithms.
* 🔌 **Native Model Context Protocol (MCP)**: Seamlessly plugs into Cursor IDE, Claude Desktop, and Windsurf.
* 🎯 **100% Mathematical Ledger Integrity**: Enforces strict Debits = Credits invariants, HMAC-SHA256 signature verification, and sliding-window fraud detection.
* 🚀 **Sub-Millisecond Financial Execution**: Designed for high-throughput payment rails and real-time ledger accounting.
