Google started to index non-hyperlinks. What to do about it?

Never seen anything like this before.

However, I noticed a massive spike of 404 errors in Search Console.

I sampled a bunch and the issues and they all seem to be the same – Google indexed non-hyperlinks as if those were links.

Here is an example of reported 404:

    https://glama.ai/docs/phoenix/use-cases-evals/rag-evaluation

Search Console says it discovered a link to this page on:

    https://glama.ai/mcp/servers/@Arize-ai/phoenix/blob/4f076b41f023e7e90c98ff7aece47bd1f1f5ebce/docs.json

If you inspect the source code of the page, there are no hyperlinks to that resource.

There are now hundreds of thousands of these cases reported in GSC.

I cannot even think of where/how to start troubleshooting this.
