Executive synthesis
What the selected evidence establishes
1 of 1 profile pair has at least one direct declared edge; 0 are connected only through a reproducible multi-hop route. The packet carries 1 exact supporting edge and 7 source-custody records: 1 route-bound and 6 profile-linked only without aggregating the profiles into a score.

U.S. mobile operating-system web usage
Mobile operating-system concentration based on the operating systems detected in U.S. mobile page views measured by StatCounter in April 2023-April 2026. The series is a public web-usage proxy rather than device sales, installed base, app-store activity, or operating-system revenue.

Research questionHow should the timing, scope, and competitive significance of the declared Observed by indicator between Market CR4 and Mobile operating systems be tested with additional observations?
Interpretation boundary
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
A dossier records the evidence route before it frames the research question.
Every audience mode uses the same profiles, paths, edges, and sources. Only the framing of the next question changes.
- 01Declare the scope
Name each canonical profile and retain its metric, period, status, and profile route.
- 02Separate route status
Direct, bridged, and disconnected pairs remain explicit throughout the packet.
- 03Publish the boundary
Carry source custody, edge guardrails, and missing evidence into every export.

The dossier frames an evidence route. Profiles, the Atlas, source dossiers, and public data remain authoritative.
