Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 6)

ScopeTrail provides cryptographically signed, portable audit receipts for AI agent delegation chains, capturing who authorized what action and when. It uses Ed25519 signatures, JCS canonicalization, and W3C Verifiable Credential shapes for stateless verification, with optional AT Protocol publishing for keyless verification. This addresses a real gap in agent accountability and provenance tracking.

Target audience: backend devs, security engineers, AI platform teams
