Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Tracelane is a Rust-based LLM gateway that proxies AI agent traffic, capturing full-fidelity OpenTelemetry traces and maintaining a tamper-evident, hash-chained audit ledger that can be verified offline. It adds observe-first guardrails, MCP tool-definition pinning, and a time-travel trace viewer, positioning itself as a flight recorder for AI agents. The cross-language ledger verifier and honest documentation of limitations are notable.

Target audience: backend devs, devops, AI/ML engineers, security engineers
