Bar length uses a logarithmic scale so low-volume lanes remain visible.Counts and shares describe encoded relationships, not economic importance, substitutability, control, liability, or antitrust harm.

Two federal program measures preserve their fiscal-year denominator and procedural meaning without converting review activity into a judgment about transactions or agency performance. HSR transaction counts and Second Request rates describe a federal notification and review pipeline. They do not measure merger harm, deterrence, legal merit, agency quality, or competitive outcomes.

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.
