How We Build Coverage

Source selection

• Primary references are official release notes, product documentation, and on-record announcements.
• Secondary references add context (industry reporting, analysis, or policy coverage).
• Lower-tier ecosystem signals are used as directional context and never as standalone proof for hard claims.

Source-basis labels

• Multiple primary sources: two or more primary references.
• Primary + supporting sources: one primary reference plus additional supporting context.
• Single primary source: one primary reference and no additional source depth.
• Supporting-source mix: multiple non-primary references.
• Single supporting source: one non-primary reference only.

Evidence and risk scores

Evidence and risk scores are editorial heuristics used to prioritize follow-up reporting. They are not scientific certainty ratings and may change as new information arrives.

Update and correction policy

• Material factual changes trigger timestamped updates.
• Confirmed errors trigger correction notes on article pages and entries on the corrections log.
• Source lists are preserved so readers can inspect provenance directly.
