One PDF, one report. Every observation cites the bytes it came from, and every check that could not run is listed with the reason.
Checking availability
Reported as LIMIT.SIZE in undetermined, not as an error.
The ceiling is a fact about the request, and the absence of observations is not
evidence the file was clean.
Checked in your browser before anything was uploaded, so nothing left this machine.
The engine reads PDF only — a file has to begin with %PDF- to be one.
Test checks here are shared, and limited so the engine stays available to everyone.
The analysis engine did not respond. Nothing was sent anywhere else.
Your document was not stored and no partial result exists. Retrying sends the same bytes to the same endpoint.
