Evidence

Data sources and methods

Every report keeps the source name, URL, publication date and access date. Core financial metrics must cite at least one source.

Source priority

  • Company filings and regulatory disclosures
  • Announcements, investor materials and management commentary
  • Regulators and authoritative industry sources
  • Cross-checked research and reporting

Data quality

Schema and semantic checks run together. Imbalanced Sankey flows, duplicate periods, unsafe content and missing core sources block publication.
