Key Cross-References

• protocol-acset: Models these protocols as attributed C-sets for compositional analysis
• protocol-evolution-markets: Prediction markets for which standards survive/merge
• mcp-spec-checker: Semantic diff engine for MCP spec versions
• did-passport-interleave: Formal bridge between W3C DIDs (ANP) and passport.gay
• aaif-governance-interleave: AAIF governance structure mapped to ASI skill graph
• captp / goblins: Capability-secure transport connecting to OCapN ecosystem

Autopoietic Marginalia

Every use of this skill is an opportunity for worlding:

• MEMORY (-1): Record which protocols are being adopted in practice
• REMEMBERING (0): Connect emerging standards to existing skill capabilities
• WORLDING (+1): Evolve integration patterns as the ecosystem converges
