compliance view here on #12 to the nearest cold water pipe

As far as the first 5 feet of water pipe being a grounding electrode vs the GEC or something else - IDK, but how does it compare to building steel or rebar making up a CEE that is extended outside the concrete? The building steel is not the true electrode, the portion that connects to earth is, and similar with rebar stubbed out of the footing for the purpose of connection to the GEC.

In most cases it kind of doesn't matter much as you can make bonding jumpers to other electrodes from either the GEC itself or from another electrode. The first 5 feet of water pipe can have a bonding jumper landed on it to another electrode, but it maybe isn't clear if it is truly the electrode or some kind of extension of the GEC which generally isn't allowed without irreversible connection means) which makes me lean toward the electrode extends up to 5 feet into the structure point of view.

How about a ground rod that has the GEC attachment above grade, but still has at least 8 feet of rod in the ground? That portion between the clamp and grade level part of the electrode or part of the GEC?
I agree that what it gets called is easily open to interpretation. But as far as the building steel to CCE or a ground ring is concerned that as well is considered a bonding jumper. Please correct me if I am misunderstanding this section.

I believed the cw 5 ' rule was showing how if attached at that point it is simply a ground rod. I would never jumper the "ground" without crimp. In some places protecting metal other than ours is required. So if I was trying to protect the water and pipes it seems that that will be done when the bond fom power meets the water heater, im not being rude or pushing a point mostly just passing on info. I have disconnected power to disconnect for h/w . All done with no power to bldg. Lifted ground to h/w heater from disc. And still had continuity from panel egc to h/w tank, flex, grond that goes to h/w pipes and everything I could reach to check. Its really super grounded from many points. C/w pipe underground to bldg steel by straps which is actually a bond to our bldg steel again then add the water back through concrete that bonds to cee by concrete. Then we pull the visible ground egc and that building is bonded and grounded more times than it appears. Note My job is to do as the code says and I do . These were my observations
