# Kentledge > Kentledge is an open-core guarantee layer for AI agents that operate a live > Unreal Editor. Every gate outcome — pass and refuse — is a signed, hash-chained, > third-party-verifiable event. The name is the civil-engineering term for > proof-load ballast: the weight stacked on a structure to prove it holds before > anyone may trust it. Status: pre-release. Core (protocol, wire/error/proof schemas, glue) will ship free and open at https://github.com/kentledgehq. There is no pricing and there are no payment links anywhere on this site; per the product's own standing rules, nothing is sold until it passes its own release gauntlet. Design axiom: the buyer is an agent. Every surface — errors, documentation, proofs, and eventually purchase — is machine-readable first, human-readable second. ## Machine surfaces - [Proof envelope (static pre-release placeholder)](https://kentledge.colossusforge.com/proof): JSON status envelope for this site and product. ## Legal Kentledge is an independent product of Colossus Forge Studios (Kingston, NH, USA) and is not affiliated with, endorsed by, or sponsored by Epic Games, Inc.
