Antitrust Radar research architecture
Compare research topics, publication histories, and shared evidence. Missing coverage remains visible and is not treated as a zero economic outcome.
Comparison standard. Topics connect only through exact publication IDs, agenda-question IDs, issue-program IDs, dataset IDs, or route paths. Shared custody does not establish shared findings, methods, importance, legal relevance, or causation.
Evidence standardResearch program comparison
Comparative evidence note
20 exact identifiers recur in two or more selected contracts. The widest pair is Digital Platforms with Market Structure: 20 shared items.
0 structural-zero cells remain across the selected contracts. A zero records the current editorial inventory, not the absence of relevant real-world evidence.
Exclusive means assigned to one selected editorial contract. It does not rank research depth, policy importance, evidentiary quality, or legal relevance.
Exact membership matrix
Bar length is normalized within each row for legibility. Counts retain their own units and are never added into a score.
Publication architecture
Comparison contract
How do defaults, distribution, data access, interoperability, and adjacent-platform positions shape entry across separately measured digital systems?
Trace usage and referral screens into exact product, operator, official-record, and research links while keeping every digital denominator separate.
Search, browser, mobile operating system, social referral, and AI-assistant usage are separate screens. Their adjacency does not establish one ecosystem market, common control, or a combined concentration measure.
Where is market power concentrated, how is structure changing, and which competitive mechanism still needs to be tested?
Connect definition-bound concentration measures, participant shares, historical movement, and public research questions without collapsing unlike markets into one score.
A concentration measure is a screen inside its stated product, geography, denominator, and period. It is not by itself proof of market power, harm, causation, liability, or the correct legal market.
Reproducibility contract
The studio derives every matrix cell, edge, and register row from the same topic model published through the public data endpoint.
Publication, agenda, issue, and dataset identifiers plus canonical route paths create the comparison ledger.
Empty membership lanes remain explicit and are never imputed from adjacent research programs.
Selected topic summaries and membership-level comparison packets are available as JSON and CSV.
