What this graph establishes

Relationships may describe different dates. A path does not establish simultaneous activity.

Bounded source-backed collection. Missing or filtered connections do not establish absence. Supported does not mean independently verified.

SUPPORTED records a source-backed assertion. VERIFIED requires an identified human review. This map does not measure supplier concentration or prove that an unrecorded relationship is absent.
