#### Epistemic boundary
`VERIFIED`, `VERIFIED_SECONDARY`, `CORPUS_V`, `CORPUS_I`, `CORPUS_H`, `STRONG_TECHNICAL_LINEAGE`, `STRONG_STRUCTURAL_CONVERGENCE`, `ANALYTIC`, and `UNRESOLVED` remain distinct relationship states. `[V]` is documented, `[I]` is structural inference, `[H]` is hypothesis, and `[OQ]` is an open question. No edge establishes ownership, funding, licensing, technology transfer, operational integration, intelligence activity, or institutional control unless its predicate and evidence explicitly do so.
