Third parties
What third parties is this site actually loading?
A consent banner lists the vendors somebody remembered to declare. This lists the hosts the page actually contacted, which is a different set often enough to matter - and for each one, the company behind it, how much it moved, and whether it blocked rendering while doing so.

What this actually is
every host contacted and the company behind itWhen preparing a privacy record and the declared vendor list came from somebody’s memory, and when a page is slow in a way the first-party bundle does not explain. The register form is the one that saves real time: it is the same reading, written out rather than read off.
Asked about this diagnostic
3 of themIs this a privacy audit of the site?
It is a list of who the page loaded and what the tables say they are. What that means for a particular jurisdiction is a lawyer’s question, and a tool that answered it would be wrong on the first page it met.
Does it catch things loaded after I look?
Anything the page requests while the panel is open is included, which covers most consent-gated loading. A script that only fires after a purchase will not appear, and no reading from outside can promise otherwise.
Why is a domain I recognise listed as unknown?
Because the tables have no entry for it. An unknown row is reported as unknown rather than guessed at from the name - the guess is exactly the thing that would make the register untrustworthy.
