I built a black box recorder for AI systems – CEL v0.2 Pro

The problem Modern AI agents make decisions, call tools, and run complex pipelines — but their logs are mutable JSON files. You can't prove what actually happened. What is CEL? CEL (Colchis Execution Log) is a cryptographically verifiable execution log for AI systems. Every event is recorded as a SHA-256 hash-chained binary frame . Any tampering breaks the chain immediately. Think Git — but for AI execution history. New in v0.2: Execution Proof bash python3 cli.py proof mylog.log python3 cli.py verify-proof mylog.log mylog.log.proof.json # → ✅ Proof VALID Share one file to prove your AI ran exactly this way — independently verifiable by third parties. Features ✅ SHA-256 hash chain — tamper-evident ✅ Execution Proof generator ✅ CLI tool (init, append, verify, dump, export, proof) ✅ Web interface (Flask) ✅ Export to CSV and PDF ✅ Compliance-ready — EU AI Act, GDPR, HIPAA ✅ Zero cloud dependency — works fully offline Links GitHub: https://github.com/GhurtSky-GR13/colchis-log CEL Pro ($99)
