Partially verified: the curator re-read none of the cited sources; S6, S7, S5, S8, S9 rest on the producer's pinned reading. Three first-person web sources: a 2017 post gives an edge-per-instruction extraction recipe (look at each page once, write an edge, label endings, render with Graphviz) and notes interest in reconvergence and cycles; the Transverse Reading Gallery states it holds 834 network graphs for 2,569 books with DOT and TGF files and edge lists; Swinehart's project classifies pages as branching, story or ending and plots page-type shares across 12 books, reporting a decline in endings and choices over time (qualitative reading of charts; no numeric table in the text read). Together they give an extraction method, open graph files and choice-density framing.
