First-party data

information collected directly from the source through direct observation, measurement, or interaction, retaining contextual detail and dimensional fidelity that no aggregation or transmission can replicate

Why This Is a Definition

This definition precisely establishes the semantic boundary of 'first-party data' by identifying its genus (information from source) and differentia (direct collection, retention of contextual detail, dimensional fidelity). It distinguishes it from second-hand reports by emphasizing what is preserved versus what is lost in transmission. The definition is consistent with the lesson's central thesis and uses terminology consistent with the curriculum's epistemological framework.
