Research memo / deterministic evidence synthesis

Competition research memo: Mobile operating systems and Market CR4

A methods-forward memo across 2 canonical profiles, preserving exact declarations, multi-hop research paths, source custody, and open empirical questions.

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.

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.

01
Declare the scope
Name each canonical profile and retain its metric, period, status, and profile route.
02
Separate route status
Direct, bridged, and disconnected pairs remain explicit throughout the packet.
03
Publish 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.
