4.1.2 Flag signals to be used at observation posts:
f) Green flag: This should be used to indicate that the track is clear and should be waved at the observation post immediately after the incident that necessitated the use of one or more yellow flags.

It may also be used, if deemed necessary by the Clerk of the Course, to signal the start of a warm-up lap or the start of a practice session.
That doesn't tell us a great deal to be honest. It would only be useful if it told us what actually gives drivers and teams the go-ahead that there are normal racing conditions. If you're in a race and you see yellows and then a green then you're racing, barring other rules of course, but then those rules will be dependant on what the track state was - hence the green flag debate and lack of safety car conditions.
Appealing on the basis of green flags alone is a red herring, but they are important in knowing what the track state was and what rules should be applied. That's the important thing.
But if another rule forbids overtaking the green flag isn't actually contradicting that interdiction.
This is at the root of it all. The problem is, there isn't a rule that forbids overtaking under the circumstances. The one that everyone thinks forbids overtaking doesn't because whatever it supposedly means is entirely dependant on whether the safety car (and conditions) was deployed at the end of that lap. Only race control could decide that because there isn't a blanket rule as there should be, and they decided it wasn't from what we've seen of the track state.
