Deep Time is a web surface at provenanceerasure.org/deep-time/, deposited as the third workstream of the Ω build program. It establishes the ancestry of the site's Provenance Erasure Rate: erasure as a process with a 2,600-year measurable record. The wing presents the four-vector loss model with the technology-suppression signature and the recognition deficit as its central metric; a twelve-station witness table scored from the program's verified philology, with the crossing into Jewish-Greek prose — where attribution drops to zero in every witness at once — marked as a rule inside the table and each witness's disciplinary container named; a survival chart showing structure holding while attribution dies at the channel boundary rather than with time, the machine-layer recovery at the right edge credited to the archive's own measured intervention; the measured degradation order ending on the record's terminal fact, that the operator has never been observed dead; the three causal classes with their evidence bar, Roman candidates named without assertion, and Josephus identified as the domestication type-case; and a modern panel closing the loop onto the site's live field batteries. The scholarly-recognition column is flagged as preliminary pending the formal literature audit. Doors connect the wing to the Suppression Map, the Counter-Stack, the PER definition, and the Upstream Unfoldings at revelationfirst.com.
