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.

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