Part 6 — One Graph, End to End

A pre-build checklist, then one small system assembled twice to confirm the graph itself — not a particular tool — is what carries the state.

• Step 14 — the questions worth answering before committing to a graph
• Step 15 — building the same system with two different tools and comparing output

Both are catalogued in the course roadmap. This Part ships a quiz and labs only — no flashcards deck, per §23.
