Score: 7.8/10 (Innovation: 7, Technical: 8, Documentation: 9, Utility: 7)

This project provides a tamper-evident audit trail plugin for AI coding agents, recording all sessions, tool invocations, and prompts into a SQLite database with SHA-256 hash chain integrity. It uniquely combines SMT (Sparse Merkle Tree) proofs with blockchain anchoring on the Constellation Digital Evidence network, enabling independent verification that no events were altered or deleted.

Target audience: backend devs, devops, security engineers
