Appendix: Knowledge Graphs

Appendix D: Knowledge Graphs (orientation aids, not arguments)

These diagrams are memory aids. They are not proofs, and they are not intended to flatten complex history into a single narrative. Use them to keep your bearings when the prose gets dense.

D1) Timeline of fractures, councils, and dialogue milestones (high-level)

D2) “Authority grammars” concept map (why people talk past each other)
