Cross-domain evidence graph

Observatory atlas

Follow documented connections between markets, firms, places, publications, and sources. A connection shows a recorded relationship, not that two measures describe the same market.

Graph contract

Relationship families stay separate

The atlas joins routes through encoded custody and context, never through name resemblance or an inferred corporate, legal, or causal relationship.

The atlas exposes only relationships declared in the current public data. A link or issue grouping does not make unlike measures comparable, establish ownership or control, define an antitrust market, assign liability, or show that a policy event caused an economic outcome.

The packet preserves node type, canonical route, relationship family, source link, evidence label, confidence, and edge-specific guardrail.
