Bilateral evidence profiles

Relationship studio

Compare two profiles through their documented relationships and shared records. An indirect connection is not evidence of a direct relationship.

Bilateral graph contract

A route is not a finding about its endpoints

Each hop keeps its own evidence label, confidence, source custody, and edge-specific limitation.

A bilateral atlas route preserves a sequence of declared edges for navigation and audit. A direct edge, common neighbor, or multi-hop path does not make the endpoints equivalent, establish ownership or control, assign liability, define an antitrust market, make unlike measures comparable, or show causation.

JSON preserves endpoints, shortest paths, common neighbors, nodes, and edge metadata. CSV flattens the complete supporting ledger.
