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.
Reusable graph packet
Carry node and edge custody into analysis
The packet preserves node type, canonical route, relationship family, source link, evidence label, confidence, and edge-specific guardrail.
