Sources

Each source is partial on its own. The Lumen Index applies one consistent lens across sources to show where external change concentrates across a portfolio.

How sources become portfolio context

Observe: ingest external items
Normalize: apply consistent schema and reliability discipline
Surface: show where change concentrates across a portfolio window

Signal coverage

The index surfaces visible external change from public disclosures and reporting. Coverage varies by source and geography, and periods without signals are common. Silence does not imply stability.
