The program has two vintages. The current 4D toy model — nine preprints, from the parent action through 4PN, plus a published moving-throat derivation archive — is the backbone of the reviewed topic pages. Some newer claims also rely on draft/future-note material, especially the moving-throat, atom, and anomaly pages. An earlier round of superfluid-defect toy model papers established the ingredients that carried forward: n = 5, the throat ontology, the initial EM and 1PN derivations. The published records are indexed below.
