OBSERVED · GRAPH-PROJECTION · NOT ADMITTED · NOT VERIFIED · NOT SUPPORT
Edge identity is the provider property id (for example P31). It is not a Counterpedia predicate.
Development requests are not available on this deployment. The observed entity and its graph links remain readable.
Relationships of Heron's formula
Legend
- Governed record relationships (solid)
- Countergraph traversal (dashed)
- Countergraph evidence (dotted)
- Observed provider relationships (dash-dot)
- Structurally derived (sparse dots)
Node shape identifies node kind only. Size, color, and position carry no meaning beyond hop distance from the root.
A line means a supported artifact carried an explicit structured relation. It does not mean the relation is true, admitted, verified, or authoritative.
