This page is the canonical source for what LOKF means. It holds the type vocabulary, the ten typed-relation fields, and the OKF v0.2 §5.4 provenance, trust and lifecycle field families that this plugin computes trust labels from (`trust-engine.md`). Its type table lists fourteen classes and names `lokf.yaml` as the complete definition. The `lokf.yaml` of the 0.8.0 toolkit also declares `Role`, so the plugin's `src/lokf-vocab.json` lists fifteen.

Its authority lies outside this repository. When a claim about the spec itself is in question, cite this page, not a paraphrase.
