A three-dimensional asset token is the archive's unit of stored data, combining an immutable binary payload, a machine-readable metadata skeleton, and a live taxonomic graph connection that encodes provenance and context.

## Structure

Each token has three components: a binary payload that is content-addressable and write-once; a metadata skeleton carrying schema-validated fields describing the content's type, provenance, and ownership; and a graph connection linking the token to its position in the taxonomic hierarchy maintained by the knowledge graph service.

The three dimensions — payload, metadata, and graph position — are written together as a single atomic record. No component exists in isolation within the archive.
