Triangulated Document Collection
Triangulated document collection is a qualitative data collection strategy in which documents from multiple independent sources are gathered and cross-checked against one another. By drawing on different document types — such as official records, personal archives, institutional reports, and media artifacts — the researcher reduces reliance on any single source and strengthens the credibility of the evidence base. The approach applies Denzin's data triangulation principle directly to documentary material.

Curated claims
Claims persisted in the evidence ledger, each with its own assessment.
This view does not invent a claim assessment when the ledger has none.
