Sources and Evidence Hub

This hub tracks where claims come from and how much weight they should carry. It separates documentary anchors from later interpretation, then links every route back to evidence quality, provenance, and citation pathways.

Institutional metadata standards

How claims are rated, what counts as strong support, and where uncertainty remains.

Confidence tiers

Evidence Tier Snapshot

Tier	Typical Source Type	Usage Rule
Tier A	Primary archival records, contracts, dated originals	Can anchor definitive chronology and baseline attribution statements.
