The Crimson Hexagon / NH-OS DOI Registry v7.0 is the March 2026 ground-truth inventory of the Crimson Hexagonal Architecture. It records 387 active DOI objects, their titles, author surfaces, types, subsystems, version relationships, and 2,851 typed edges.
The Registry is functionally distinct from the Central and Fractal Navigation Maps. The maps route and resolve traversal; the Registry enumerates what existed in the documented archive state. It therefore serves as a historical dataset even after later repository growth.
Version 7.0 introduces five enrichment layers. The précis layer supplies extracted one-line descriptions for 348 records. The relation graph records citation, reference, and supplementation edges. Subsystem classification distributes records across nineteen architectural domains. The document-type taxonomy applies eighteen resource classes. Provenance-gravity tiers group records by relation density, distinguishing structural anchors from active theory, supporting material, and peripheral records.
The registry also exposes unresolved structure. Thirty-nine records have no graph edges, and additional records remain unclassified or incompletely typed. These are not concealed; they are preserved as orphan and pending states for later architectural work.
Its version history tracks expansion from 91 records in v1.0 through 200 in v5.0, 251 slots in v6.0, and 387 records in v7.0. Major v7 additions include the Space Ark, NLCC, Three Thresholds, TANG, the first field container, Dolphindiana, and new transform and effective-act sequences.
