Show HN: CEL v0.2 Pro – cryptographic black box recorder for AI systems (Python)

I built CEL — a tamper-evident execution log for AI agents. Every decision is recorded as a SHA-256 hash-chained frame. Think Git — but for AI execution history.

New in v0.2: Execution Proof — one file that cryptographically proves your AI ran exactly this way.
