Executive synthesis
What the selected evidence establishes
0 of 6 profile pairs have at least one direct declared edge; 6 are connected only through a reproducible multi-hop route. The packet carries 4 exact supporting edges and 1 source-custody record: 1 route-bound without aggregating the profiles into a score.

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.
Research handoffs

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