K-Pop stack-rank vertical
One SBPI vertical mirrored as a flat set of same-type concepts: eight weekly brand documents plus their scoring and prediction sheets, most enriched by the two-pass dotprompt producer. The shape a vertical has when an agent first meets it — one type, one dominant cluster.
Totem Persona (shuriq-jonny)
A persona exported from the DKR ingestion and ontology design process: 29 concept types, densely cross-linked with plain markdown links. Every concept is a Layer-2 projection whose resource: pointer resolves only through the gated endpoint — the firewall, visible in the file.
Value-flow REA model
A generic specialty-coffee value chain in REA semantics: every economic event links its provider agent, receiver agent, and the resource that moves — join paths, the way a relational schema would draw them. Classes resolve to the shared REA meta-ontology bundle.
What the three shapes prove together
The format does not change; the graph does. A flat vertical, a dense typed persona, and a directed join-path model all travel in the same envelope: a folder of markdown files with one required frontmatter field. That is the property that makes OKF a safe export boundary — expressive enough to carry structure, too poor to carry the deep model.
