Score: 5.0/10 (Innovation: 6, Technical: 4, Documentation: 3, Utility: 5)

Lineation is a security control plane for AI agents that provides unified policy enforcement, tracing, and defense across multiple agent frameworks. It aims to solve fragmented visibility and over-permissioned tool risks by offering immutable lineage from prompt to tool to data. The project is interesting for its agent-native approach to security, but remains early-stage with minimal public documentation.

Target audience: security engineers, devops, AI platform teams
