I was just referring to the rulebook description of how Approaching Army works. For Ways of course all we have is the rulebook description, so that is a difference. I'm not trying to say that Approaching Army should work with Harbor Village. From the card text it doesn't. That's why I said it's unfortunate that from the rulebook description it does.
When you say rulebook description, is this in the FAQ? Or somewhere else in the general rules? Just wondering because I believe we've seen places in the past where the FAQ is less technically accurate than the card wording. But with Ways, as you say, they're just just a helpful description to clarify things, they're the actual rules definition of what Ways do.
Yes, the "notes". That's the only place the individual cards are described in the rulebooks.
I think you have the wrong idea about the rulebooks. There is no difference between the "notes" section and the other parts; none are necessarily technically accurate. There is always a balance between technical accuracy and understandability through more plain language. The idea is that people should be able to understand how to play in most normal situations.
An example: In that other long thread about Harbor Village, we talked a lot about the difference between Ways and Adventures tokens. Way of the Sheep supposedly makes the card "give you" +$1, while the +$1 token doesn't. And the basis was always the rulebook description of Ways. You even mentioned how the section on Adventures tokens doesn't say this. But actually it does: "A Duration card still just
gives the bonus when played, not on the next turn." (My emphasis.) The rulebook is not being technically accurate there.
The cards themselves are not always technically accurate either, and the rulebook "notes" give the fuller picture. For instance, there are several extra rules for Divine Wind that we need to read the rulebook to know. Or River Shrine - the card is not clear whether it's just the last Buy phase or any of them, but the rulebook clarifies. As Donald X. has said, the cards can't be like computer programs. (Although in many respects, and on most cards, they do work pretty well as such.)
So we need both the card texts and the rulebooks to understand how to play the game. Of course there are still many interactions that are not covered at all (and then we need rulings instead), precisely because neither the cards or the rulebooks are complete or technically accurate for all scenarios.
