The scraper got HTTP 200, but found nothing

What it looks like

The request receives HTTP 200 and the scraper exits normally, while items_found is 0.

Why a heartbeat is green

Transport success says the source answered; it does not prove the expected records were present or parsed.

Expectation that catches it

Add an output expectation that warns when items_found is less than 1.

Report it to Glnc

Send the parsed item count after validation so a changed page or empty payload cannot hide behind HTTP 200.
