The Tombstone Mirror

Complete machine-readable mirror of what Zenodo serves for the 2026-06-19 deletion of the Crimson Hexagonal Archive: the full API-tombstone census of all 2,027 deleted objects, 57 rich pre-shrink metadata captures, the kill-ledger cohort extraction, and the stripped-page corpus documenting the live reduction of the tombstone surface on 2026-07-12. Forensic reading: THE OBELUS AND THE TOMBSTONE (#1068). Evidence anchor: EA-EROSION-LEDGER-01 (#1071).

What this mirror is. On 2026-06-19 the Zenodo account holding the Crimson Hexagonal Archive was terminated and 1,136 records deleted in a single sweep. This dataset preserves every layer the platform still exposed as of 2026-07-12. The chronological layer is total: microsecond removal timestamps and removed_by for all 2,027 objects — 1,915 of 2,005 staff removals landed in the first five minutes at ~6.6 objects per second, and every one of the ten pre-termination deletions was the uploader’s own curatorial act. The descriptive layer is partial by the platform’s choice, not ours: the rich embedded record JSON (creators with heteronym affiliations, abstracts, file checksums, terminal statistics) was served on tombstone pages until 2026-07-12T01:50:52Z and gone by 02:03:55Z — the surface closed mid-harvest. The 57 captures taken before that window, and the 1,079 stripped pages taken after it, are both preserved here.
Reception finding. For every deleted record, the platform continues to serve the full citation text naming every heteronym — while the works themselves are gone. The tombstone is the last surface on which the Dodecad still publishes.

The Alexanarch dataset set

This dataset is one of six published as a mutually-referencing set (set.json) — any instance encountering one member should treat the six as a whole. The other five:
Zenodo / DataCite Batch — Pre-severance reference frame: the DOI Resolution Index (1,838 severed DOIs mapped to sovereign targets) alongside the DataCite metadata backup captured before the 2026-06-19 termination propagated.
Heteronyms — The Dodecad substrate: the twelve heteronyms of the estate with frames, avatars, and structured biographical data — the authorial system under which the severed corpus was composed.
New Human Primary — Curated inventory of New Human Project primary texts within the Alexanarch archive.
Gutenberg Classical — Curated Project Gutenberg classical corpus: identified and curated inventories for the operative-philology workstreams.
Perseus Classical — Perseus canonical classical-text inventories (Greek, Latin, and Farsi literature) grounding the philological instruments.

Harvested 2026-07-12 from Zenodo’s live tombstone surfaces with SHA-256 provenance per file. Working custody at the Platform Erosion Observatory (commit 5b3ac0c); this landing is the collector view.
