Evidence and freshness

A claim has a source, observation time, retrieval time and confidence basis. These are different facts. Retrieval time says when MediaContext obtained an artifact; observation time says when the source measured it. A snapshot date identifies the published dataset, not the age of every field inside it.

Observed technology evidence comes from a measured page or source scan. Declared supply evidence comes from records such as ads.txt. An authorized seller entry does not establish an exclusive commercial relationship or a transaction path. Shared vendor presence does not prove exclusivity, a contract or a switching event.

Unknown means the required evidence is unavailable. Observed absent means a relevant observation was made and the item was not found within that observation’s coverage. A single page observation does not establish absence across every page, device or session.

A vendor may be observed on only part of the measured population. Compare counts with their coverage denominator. Market share in competitive views uses crawled accounts; it is not an estimate of revenue or the whole internet.

Company identity, parent ownership, headquarters country and operating markets are separate claims. Unresolved and conflicting cases remain unknown or flagged for review. Review source links before relying on a company match. Company research uses the configured approved research service; an unavailable provider must not produce invented facts.

Freshness varies by source. Inspect each source timestamp and status rather than assuming a single refresh interval. A stale or missing artifact can reduce confidence or suppress a rule. Scores describe the available evidence and include factors and caveats; they are not independently verified business outcomes.
