What a source marker means
A numbered marker means that the linked source supports or contextualizes the adjacent statement. It does not mean GroundingWiki endorses every statement on the source page.
Preference order
Legal and operational facts begin with first-party or government records where available. A first-party source is a page published by the entity, its operator, or a responsible authority. The label describes that source, not the page on which a reader happens to see it. A page found while reading a first-party site, or cited by Wikidata, stays an independent or structured-public source unless that publisher test is met. Independent sources are used for corroboration, context and contested claims. Discovery records how a URL was found. Discovery is not public evidence until the page itself has been read and the claim has been checked against what that page says.
What one source can support
One source may support several claims. Each claim keeps its own evidence summary, so the same source number can explain a legal name in one place and a register number in another. The host of a URL is not the same thing as the publisher. When the issuing organization is not established, the reference shows the site host instead of a guessed publisher name. A company filing hosted by a regulator, such as an SEC EDGAR document, is labeled a regulatory filing. A government register record stays a government source. Some public sentences, including a short definition or a category placement, are composed from several separately sourced claims. A derived sentence may show several markers. No single source is implied to contain the full editorial wording. Each marker opens the evidence for one of the underlying claims. Checking a source, verifying a claim, and reviewing an entity are separate dates.
Evidence dates
The checked date records when the source was inspected. It is separate from a source publication date and from any period during which a claim is valid.
