Enum Subject 

pub enum Subject {
    Campaign,
    Engine,
}

Whose state a code’s verdict is about.

The question this answers, and the only question it answers: if the author changed nothing about their campaign and the engine’s own tables were finished, would this line go away?

Variants

Campaign

The campaign. Every refusal, and every advisory whose verdict is a fact about the documents in front of the author — the default, because a diagnostic is addressed to an author unless it says otherwise.

Engine

The ENGINE, regardless of the campaign: an engine table that is still seeded, a standard that has not been calibrated. Nothing the author can write moves it, and it is identical on every campaign the engine compiles, so it prints after the lines that ARE theirs — see Group.

This is not a licence to make a campaign’s problem quiet. The test is whether the line would read the same on a different campaign; where it names something the author wrote, it is a Subject::Campaign verdict however advisory its tier.
