Start exact, then widen carefully
The first pass uses the complete normalized address because exact references are less ambiguous than a common display name. The engine can look for public pages that repeat the address and identify surrounding names, aliases, organizations, websites, and profile links. The domain also supplies context: a personal provider, school, employer, organization, custom domain, and disposable provider each imply a different research path.
The second pass treats the local part as a candidate handle, not a confirmed account. A local part such as first.last may map to many unrelated people. A distinctive alias that appears beside the same website, location, biography, or profile image can be more useful. A username available in a social URL is not evidence that the email owner controls it.
The final pass compares independent details across sources. A consistent name, location, organization, linked website, public biography, image, and second verified identifier can raise confidence. An old date, copied directory entry, unrelated biography, or conflicting location must lower it. Source agreement matters more than the number of search-result snippets.
