Executive synthesis
5 of 15 profile pairs have at least one direct declared edge; 10 are connected only through a reproducible multi-hop route. The packet carries 11 exact supporting edges and 4 source-custody records: 4 route-bound without aggregating the profiles into a score.
Canonical scope
How do defaults, distribution agreements, data access, and adjacent-platform positions shape entry across separately measured digital systems?
All-platform U.S. search engine usage share from StatCounter Global Stats for April 2026. The market is an observed usage-share proxy, not search advertising revenue.
Search engine participant reported by StatCounter.
Official operator label associated with Google Search Chrome Gemini Android and YouTube.
The court prohibited specified exclusive distribution contracts and ordered access to certain search index and user-interaction data plus search and text-ad syndication services.
Monthly public StatCounter all-platform search engine share export for the United States.
Priority routes
1 exact declared edge: Issue program membership.
Research questionHow should the timing, scope, and competitive significance of the declared Issue program membership between Digital gateways and Search engines be tested with additional observations?
1 exact declared edge: Source-labeled participant.

1 exact declared edge: Market evidence custody.
Research questionHow should the timing, scope, and competitive significance of the declared Market evidence custody between Search engines and StatCounter Global Stats be tested with additional observations?
1 exact declared edge: Official product attribution.
Research questionHow should the timing, scope, and competitive significance of the declared Official product attribution between Google Search and Google be tested with additional observations?
2-hop declared route through Search engines. The path is reproducible but does not establish a direct endpoint relationship.
Research questionWhat additional evidence would be required to test a direct hypothesis about Digital gateways and Google Search rather than relying on this multi-hop research route?
The workspace assembles canonical profiles and declared Atlas edges for research navigation. A direct edge preserves only its encoded evidence statement. A multi-hop route does not establish a direct endpoint relationship, make unlike measures comparable, define a legal market, assign ownership, control, liability, or causation, or prove a policy effect.
Profile-linked custody records document the selected profiles. They do not substantiate a selected pair route unless the same source also appears on a route-bearing edge.
Publication standard
Every audience mode uses the same profiles, paths, edges, and sources. Only the framing of the next question changes.
Name each canonical profile and retain its metric, period, status, and profile route.
Direct, bridged, and disconnected pairs remain explicit throughout the packet.
Carry source custody, edge guardrails, and missing evidence into every export.
Research handoffs
The dossier frames an evidence route. Profiles, the Atlas, source dossiers, and public data remain authoritative.
