Multi-profile evidence composition

Research workspace

Collect profiles and sources for a research question. Compare the recorded relationships without treating a shared connection as proof of equivalence or causation.

Source custody

No source-bearing edge is present in this layer.

01Every selected item remains a canonical profile with its own metric, definition, period, and source boundary.

02Direct means an exact encoded Atlas edge. It does not expand the underlying evidence statement.

03Bridged means a reproducible multi-hop route. It never becomes a direct endpoint relationship.

04The workspace does not infer equivalence, ownership, control, liability, causation, or policy effects.
