Okay. So we start at the top.
Wire 1 is green, so we don't cut it. We look at the wire below.
Wire 2 is green and red. "If the wire is red, cut it." If we're going through the rules in order of introduction, this means we would cut it normally before we evaluated its greennness, so we don't cut it.
Now Wire 3 is where the rules get a little confusing. We already evaluated Wire 2 in the process of evaluating Wire 1. However, Wire 2 is green. Does this mean we look at Wire 2 and its greenness, which would mean we cut this one? Or do we skip Wire 2 because we already figured out we don't cut it?
If we evaluate Wire 2, then we cut Wire 3 because we normally wouldn't. Otherwise we don't cut it.
Oh, but wait, that's what we'd have if Wire 2 was only green. Because it's red, if we evaluated it we'd conclude "cut it"... but do we still get as far as considering its greenness when that can affect a wire we haven't cut yet? Oof, this is confusing.
Whichever way things go: Wire 4 is below Wire 3. It counts as red and blue. We would normally cut it for being red, so we don't cut it here.
In regards to rule interactions on this step: we are either considering Wire 2's greenness even though we already worked out whether to cut it, so we should do the same for Wire 3; or we are skipping Wire 2 because we already worked out not to cut it (or we're not skipping its evaluation but we don't get to its greenness because it's red) and therefore we're evaluating Wire 4 based on Wire 3. It's not clear exactly what we're doing, but any possible interpretation of how the rules are to be applied means that we don't cut Wire 4 because Wire 3 is green.
Wire 5 is red, so we cut it.
Wire 6 is red, blue, and green. It's red, so we cut it.
So: Running through the rules in order of introduction, we definitely cut 5 and 6. The question is whether we cut 3 or not. This depends on a couple of rule interactions that aren't entirely clear:
-If we have already determined whether or not to cut a wire (which currently can only happen with the green rule), do we still evaluate it for its potential to affect the wire immediately below it?
-If a wire has multiple colors, once we have a rule that tells us whether to cut it, do we still consider other rules that may affect whether we cut the next wire?
If the answer to both questions is YES, then we DO cut wire 3. If the answer to either question is NO, then we DO NOT cut wire 3.
I could see if Reyweld will clarify the rules, but it's more fun to clarify through experimentation. So: cut 5+6 only. If this doesn't work, we know that we always have to evaluate a wire's ability to affect wires below it, even once we've worked out whether or not to cut that wire.
