OpenChainGraph Suite ยท CG-27 ยท Post Oak Labs

One persona. One guided journey.
Every step a verified artifact.

Each OpenChainGraph bundles a persona's decision journeys behind an up-front selector, then walks them step by step. Every step exports a Policy Mandate artifact carrying a SHA-256 execution_hash โ€” and that hash chains into the next step. Client-side, zero-egress, MCP-exposed.

The graph beneath the journeys

The 145 individual tools are the graph's nodes; the 13 persona OpenChainGraphs are the journey edges that bind them. Every artifact is reproducible and chainable.

Machine-readable graph index โ€” every node, its Policy Mandate type, and its chain edges. The primary LLMEO surface, linked from llms.txt. View โ†’

Policy Mandate + execution_hash

Each step exports a valid Policy Mandate artifact whose SHA-256 execution hash is the precondition for the next step. Verifiable client-side.

Zero-egress

All computation in-browser. No data transmitted, no storage, no PII. CC BY 4.0.

Learn OpenChainGraph, the standard behind this suite

OpenChainGraph (OCG) is an open standard for turning a browser tool's output into a verifiable, agent-callable artifact: every step hashes its inputs and result, and that hash chains into the next step, so a reviewer or an AI agent can confirm what ran without re-running it or trusting a screenshot. ApexLogics is one live implementation; the standard's home base, tool catalog, and full technical writeup live at AINumbers.co.
