Appendix — The book's graph (live)
State of the art captured in 2026-07 · last revised 2026-07-30 · history and expiration log
Every technical book is a graph disguised as a sequence: chapters that cite each other, systems that show up across several dimensions, concepts that stitch it all together. This page makes the graph explicit — and interactive.
How this graph is built (and why it never goes stale)
The nodes and edges are neither hand-edited nor generated by a model: they are extracted deterministically from the Markdown itself on every site build, by the publishing engine (publicar/grafo.mjs). A chapter→harness edge exists because that chapter mentions that system in the text — with a weight equal to the number of mentions (Principle I: every edge is verifiable textual evidence). Since the build runs on every published change to the book, the graph tracks the content by construction — updating it is not a process, it is a property.
- Nodes (4 types): the 18 chapters; the 16 systems in the study corpus; key concepts (MCP, A2A, ACP, LSP, RAG, MAST); the 13 harness-zero steps.
- Edges: chapter→chapter ("ch. NN" cross-references), chapter→system (mentions), chapter→concept (occurrences), chapter→step (the Hands-on track).
The interactive graph
(The visualization exists only in the online version — in the PDF this island is omitted by definition.)
Reading guide
- Hubs: the larger nodes concentrate connections — expect to see ch. 02 (Loop) and systems evaluated across every dimension as gravitational centers.
- Bridges: concepts like MCP connect groups that would otherwise sit far apart (ch. 06 to ch. 17, the corpus to the protocols) — the book's stitching made visible.
- The practical track: filter by "harness-zero" to see how the steps tie the theoretical chapters to the build (Backward Design in graph form).
