Secondary Source (EA-SECONDARY-SOURCE-01, version 1.2) is a reception-history study by Johannes Sigil, a heteronym of Lee Sharks, deposited in the Crimson Hexagonal Archive on 5 November 2026 for Provenance: Journal of Forensic Semiotics and reissued in place on 5 and 6 November. It is the companion of Legitimately Many (#1733) and asks how a unified corpus came to be treated as many, later reconciled through editing. The study holds the Revelation First position: the Apocalypse is the generative source of the New Testament, the fulfilment of the law and the prophets as literature, from which the letters and the gospels unfold. It reads the reception locus by locus in seated sources (EA-CORPORA-34, #1740) with a locus table of 65 loci. Its primary finding is that the earliest witnesses hold the gospel and the gospels together, bring in composing persons to explain differences without arguing their distinctness, assign the corpus's unity to a spirit, and never consider a single making; the critical apparatus of the nineteenth and twentieth centuries inherits the persons and explains the unity by editors, redactors and reconstructed sources such as Quelle A and Q. The derivation of the Apocalypse is the central case: the reception supplies the book with ancestors, reads the relations running out of it as parallels or answers them on other questions, and installs the generative position in the gospels and in reconstructed documents, while Irenaeus founds the fourfold gospel on the book's own four living creatures. The passage of the four names, Revelation 19:11–16, is read intact as the countercase, against critics who each removed one name. The study proposes that the reconciliation reading creates an intermediary's position, the editorial apparatus as the corpus's first summarizer layer, and tests ten AI Overview compositions against a frozen prediction. Version 1.2 adds a kernel mapping ten arguments toward the book as originary, each with the earliest treatment that left it open and the later stratum that closed it, and an SPXI packet.
