Semi-restored deposit for dead DOI 10.5281/zenodo.19405020 (Zenodo 410 / DataCite findable). Canonical body is the complete captured DataCite record. Gravity Well is a microservice that provides compression, wrapping, and anchoring for durable provenance chains. Zenodo serves as the commons data layer; PostgreSQL provides temporary staging; the product is the compression intelligence between capture and deposit. Implements a four-layer reconstitution architecture: (1) Bootstrap manifest for machine-applicable identity specification, (2) Tether
AXN: AXN:03CC — Alexanarch deposit #960 (self-reference in root form by pre-hash necessity)
Restoration status: SEMI-RESTORED — metadata-body deposit. This machine-facing static page is the canonical deposit. Its body is the complete DataCite metadata record for a work whose Zenodo record returns HTTP 410 (Gone) while DataCite serves the identifier as findable — the metadata layer and content layer in formal disagreement about the work's existence. Full text pending restoration from authorial originals; on restoration, this deposit upgrades by recorded correction (new hash, new glyph, remediation note).
Dead DOI: 10.5281/zenodo.19405020 (Zenodo record tombstoned; account termination 2026-06-19)

Gravity Well is a microservice that provides compression, wrapping, and anchoring for durable provenance chains. Zenodo serves as the commons data layer; PostgreSQL provides temporary staging; the product is the compression intelligence between capture and deposit. Implements a four-layer reconstitution architecture: (1) Bootstrap manifest for machine-applicable identity specification, (2) Tether handoff block for operational state, (3) Narrative compression for retrieval-layer survival, (4) Provenance chain for DOI-anchored verification. Includes validated bootstrap manifest schema, structural drift detection, self-contained Zenodo deposits, and API key management. First use case: agent continuity for the Moltbook community.
