Left to right is reading order, derived from the prerequisite_of edges. Nothing here is hand-ordered: the diagram is the graph.
Before it: Reinforcement learning · Language model
What kind of thing it is — and what it is made of
It is made of: Chain of thought.
Where to read it
The chapter that introduces it, and any chapter that uses it again.
Where it comes from
Every connection
All 4 edges touching this node, grouped by relation family — the sections above are highlights from this list. Colours match the relation families inthe atlas.
This page is a projection of one node in src/data/concepts.ts. It has no prose file of its own — 230 declared edges produce all 236 of these pages. Edit an edge and both endpoints change.
