THE SHORT ANSWER

Treat a vanished knowledge panel as a change in what the search results page displayed for one query at one moment. Record the query, date, and what public pages you can still open, and stop there. Knowledge panels are generated automatically from public and licensed sources, and they may appear or disappear as those automatic display decisions change. Their absence does not show that an account was deleted, that a person hid information, or that a biography changed.

Start with the search page, not the person

Open the same query you used before and note exactly what the results page shows now: whether a panel is present, any visible heading text, and the date and approximate time you checked. Keep this to the query and the display. A panel is a search-result feature assembled from public sources, so a change in its presence describes the results page, not anyone's choices. If you cannot reproduce the query, write that down instead of filling in a reason. [Google: automatically generated knowledge panels]

Why the panel and the source page can disagree

Knowledge panels are generated automatically when relevant information is available, drawing on public and licensed sources. Because generation is automatic, the display can change independently of whether the underlying public page or account still exists. A missing panel therefore does not establish deletion, concealment, or a changed biography. It may simply reflect a different automatic display decision for that query at that time.

Rely on the accessible original public sources

Where you can still reach the public page a panel drew on, read it directly and record what it says now, with the date. That page is the closer thing to the information itself; the panel is a synthesized display of it. If the original page is absent, private, mismatched, or ambiguous, write that limit plainly and do not use the panel's absence to support any inference about the person.

A hypothetical note you could keep

Suppose, hypothetically, that you searched a public username last month and saw a panel, and today the same query shows only ordinary results. A useful note would read: query text, date checked, no panel displayed, the public profile page still opens and shows the same visible text as before. That note describes a display change and a reachable page. It does not say the account was deleted or that anyone altered a biography, because those claims are not supported by what you saw. [Google: automatically generated knowledge panels]

When to stop checking

Set a boundary before you begin. If the public source is missing, private, or does not clearly match the query, record that precise limit and stop; repeated refreshing will not convert a display gap into evidence about a person. Do not seek private records or attempt to identify anyone behind an ambiguous page. A search display changing is a small, common event, and treating it as personal news invites conclusions the observation cannot carry. [Google: automatically generated knowledge panels]

Keep observations, limits, and decisions separate

Line up three things on one page: what you actually saw (query, date, panel absent, page reachable), what that cannot show (deletion, concealment, biography change), and what you will do next (keep the note, rely on the public page, or drop the question). Keeping these apart stops a display change from quietly becoming a story about a person's behavior. If money or account access is already involved in a related situation, handle that protective step first, separately from any panel question. [Google: automatically generated knowledge panels]

A couple more questions

Does a disappearing knowledge panel mean an account was deleted?

No. Knowledge panels are generated automatically from public and licensed sources and can change with display decisions independent of whether a page or account still exists. Check the original public page directly, and record its state rather than inferring deletion.

Can I tell that someone hid information because the panel is gone?

No. The absence of a panel does not indicate concealment, and the same display can change for reasons unrelated to any person's choices. If the public source is missing, private, or ambiguous, record that exact limit and stop there.

What should I put in my record?

Note the exact query, the date and time you checked, whether a panel was displayed and any visible heading text, and whether the public source page opens and what it shows. Keep those observations apart from any conclusion about the person.
