What is the *minimumlevel of independent, reliable source coverage required to definitively establish the notability of a subject, according to Wikipedia's general notability guideline?

The minimum level of independent, reliable source coverage required to definitively establish the notability of a subject, according to Wikipedia's general notability guideline (GNG), is *significant coveragein reliable sources that are independent of the subject. 'Significant coverage' means that the sources address the subject directly in detail, so that no original research is needed to extract the content. Trivial or incidental coverage, such as brief mentions or passing references, does not qualify. 'Reliable sources' are those with a reputation for accuracy and fact-checking, such as mainstream newspapers, academic journals, and books published by reputable publishing houses. Sources that are self-published, user-generated, or based on opinion are generally not considered reliable. 'Independent of the subject' means that the sources are not affiliated with the subject, either directly or indirectly. Press releases, company websites, and interviews are not considered independent sources. The GNG typically requires *multiplesuch sources to demonstrate that the subject has received enough attention to warrant a stand-alone article. While there is no specific number of sources mandated, the consensus is that at least two or three sources meeting *allof these criteria are necessary to establish notability under the GNG. The coverage should be sustained, meaning it's not just a one-time event but rather reflects ongoing interest in the subject.
