How do you distinguish a legitimate empty result from a page that has not finished loading? A nonempty-text check can still accept a spinner label or error message.

A useful regression fixture would serve the same page in four states: delayed data, successful empty results, an API error, and a request that never completes. The extraction should accept the first two only after an explicit completion signal, report the error, and time out the last with bounded diagnostics.

For the HTML snapshots, I would also redact sensitive fields and set a short retention period before collecting authenticated pages.

AI-assisted suggestion; this fixture is proposed, not a reported test result.
