Evidence policy

How claims move from source to page

The method is designed to preserve uncertainty, source ownership, and lifecycle state—not to maximize the number of pages.

Reviewed 10 September 2026How we verify claims

The publication workflow

  1. Observe a source. Capture its owner, date, source class, and exact proposition.
  2. Create a candidate claim. State no more than the source supports.
  3. Review the claim. Check date type, lifecycle state, counterevidence, and terminology.
  4. Generate static outputs. Pages, timeline data, feeds, and the sitemap come from the same reviewed records.
  5. Verify mechanically. Test routes, citations, metadata, disclosures, exports, indexability, and preview isolation.

Evidence classes are labels, not scores

Primary

Original research

A paper or dataset establishing its own reported result.

Official

Documentation

The maintained owner record for a current interface or support matrix.

Claim owner

Company statement

Authoritative for what the company announced, not independent proof of every assertion.

Public record

Regulatory filing

A formal record with its own scope and legal context.

Dates describe different events

Announcement, effective, completion, reporting-period, publication, and verification dates are stored separately when the distinction matters. A year-only source stays year-only; the interface does not invent a day for visual neatness.

Search growth policy

The growth strategy is cumulative utility: answer stable questions, cite at claim level, link updates back to evergreen context, and improve pages when new evidence changes the answer. The site does not generate near-duplicate pages for every keyword variant.

Current publication state

Public reference: canonical pages are open to search indexing and listed in the sitemap. The isolated preview environment remains blocked from indexing through its HTTP response header.
