Partially verified: the curator re-read none of the cited sources; S16, S17, S18 rest on the producer's pinned reading. In the three open arXiv papers read, no standard reconvergence or choice-density metric for authored branching stories is defined. MACHIAVELLI reports corpus scale only (134 games, 572,322 scenarios, 4,559 achievements). CHADPOD builds 1,462 decision-point classification tasks from CYOA graphs. Forking Garden (2026, LLM story-graph generator) defines an entity-overlap edge score and reports an entity-diversity ratio of 0.678 versus 0.261 for a baseline, a paper result on generated graphs, not on authored works.

Curator qualifications: Partially verified: the curator re-read none of the cited sources; S16, S17, S18 rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S16: HTTP 200, bytes differ from the producer pin; S17: HTTP 200, bytes differ from the producer pin; S18: HTTP 200, bytes differ from the producer pin.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
