## Pre-flight checklist

- This is an API feature request, not a consumer app or Comet UI request.
- Check current documentation and forum topics for closely equivalent functionality before posting.
- The developer workflow or API use case is described below.

## Feature type

New response field or metadata; New endpoint or API capability

## Affected API area

Search API; Agent API

## Summary

Expose source dependencies so multiple agreeing publications are not automatically counted as independent confirmation.

## Problem

Five articles can repeat the same original allegation or study. Citation count alone does not demonstrate independently obtained evidence.

## Proposed API behavior

Provide optional source lineage metadata linking citations to their originating records, known reproductions, independent observations and unresolved source relationships. Proposed fields: origin\_record\_ids, derived\_from, corroboration\_basis, independence\_status, assessment\_method, limitations. Unknown lineage must remain unknown, not be labelled independent.

## Example usage

An analyst retrieves three reports citing one underlying dataset. The API marks the common dependency and separately identifies any additional independently produced measurements.

## Workarounds tried / considered

Manual bibliographic tracing and citation graphs exist, but typically require project-specific integration; no automated lineage test or benchmark has been conducted here.

## Impact

Researchers and developers can avoid double-counting evidence and improve dispute analysis; careful provenance indicators can improve reliability without promising truth.

## Additional context

Related forum requests discuss citation validation and fact-checking. The proposed scope here is specifically evidence-origin dependencies and independence, not another fact-checking agent.
