Question, mandate, boundary, and evidence need

Public question

What can current public records establish, where do measurement boundaries stop, and which disclosures would make antitrust research more accountable?

Institutional mandate

Document definitions, denominators, source construction, release clocks, reproducibility paths, and evidence gaps as first-class research outputs.

Interpretation boundary

A documented data gap is not evidence of competition or harm. Screening thresholds are not legal conclusions, and reproducibility does not make unlike measures comparable.

Evidence still needed

Stable identifiers, machine-readable firm shares and ownership, local boundaries, historical revisions, disclosure status, methods documentation, and durable public APIs.

Primary audienceData publishers, analysts, students, reporters, agencies, and legislators
