Official-record interpretation boundary

A record dossier preserves what one dated official source says and the observatory context linked to it. It does not convert allegations into findings, findings into economy-wide conclusions, or nearby market indicators into causal effects.

A linked market identifies the observatory context assigned to this record. It is not necessarily the relevant antitrust market alleged or adjudicated in the official matter.
