The Upstream Unfoldings is a web surface at revelationfirst.com/upstream/, deposited as the second workstream of the Ω build program. Complementing the site's Algorithmic Kernel, which demonstrates Revelation unfolding forward into the later New Testament, the page runs the opposite direction: six operable transforms carrying the frozen Sapphic apparatus through the tradition that feeds the Apocalypse. The plates present Longinus performing the operation at the quotation-joint; Philo legislating the machine as doctrine with the name absent; the Greek Esther's Addition D intensified into Antiquities 11, with Josephus's two restorations toward the poem tabled station by station; the Bellum's inverted realization stitched by the rare reactivation verb; the Slavonic carrier presented with its contested status, negative search, and per-passage provenance displayed rather than suppressed; and Revelation 12 as the counter-stack's first transform-view edition — the seated Nestle 1904 text with station chips, a text-transform toggle, the sealed test's scorecard including the doubled station and the outright C1 failure, and the negative findings printed in red on the page. Every quotation is drawn from the archive's commit-pinned, checksum-manifested corpus seats, making the surface's provenance inspectable end to end, and the page closes by stating what it does not assert.
