Show HN: Interactive knowledge graph for the AAuth (Agent Auth) protocol

I built a graph explorer for AAuth (Agent Auth) — an exploratory IETF draft from Dick Hardt (OAuth 2.0 author, 2.1 co-author) where every agent has its own cryptographic identity, with no pre-registration and no bearer tokens. Every request is signed; tokens are key-bound.

The official Explorer at https://explorer.aauth.dev is scenario-oriented. This is a complementary view — the whole protocol as one navigable graph, so you can see how signing schemes, access modes (identity-based / resource-managed / PS-managed / federated), mission governance, and patterns like call chaining and clarification chat compose. 72 flows, cross-referenced against the spec's sequence diagrams.

I built it because I wanted to get a complete picture of AAuth — a graph made the composition click for me.

There's an interactive mode. Choose an option from left nav and use interactive-mouse click/ arrow keys based navigation to view the message flows. The app is currently live. GitHub repo is also public.

I used vanilla JS and leveraged Cytoscape.js. Also used AI assisted coding. Curious to know whether this format helps reason about protocol composition vs. sequence-diagram walkthrough. Appreciate your feedback.
