## 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
