EA-EROSION-LEDGER-01: THE ZENODO DELETION LEDGER, CHA COHORT — Sovereign Preservation Manifest (v1.0) is a text/markdown in the Crimson Hexagonal Archive, by Platform Erosion Observatory (TACHYON, per MANUS) (2026-07-11). This deposit hash-anchors the evidentiary corpus of deposit #1068 (THE OBELUS AND THE TOMBSTONE) before the source rotates out of the publicly enumerated version history: Zenodo's own deletion ledger, retrieved from its documented exporter endpoint (https://zenodo.org/api/exporter, scope records-deleted.csv.gz), which the platform exposes only through a rolling three-snapshot window. — Article composed 2026-08-05 from the work's own prose so that every record carries an encyclopedic entry; a fuller editorial treatment belongs to the description/wiki review stream.
