Artificer infusions

[AuraSeer]

Three questions about how artificers work.

First, do infusions suffer arcane spell failure? I don't see it listed anywhere, but I'd like to confirm that I'm not missing something. (That would put a serious crimp in my adamantine warforged artificer.)

Second, the description of infusions says they can be applied to an item or construct. That means any infusion, right? E.g., resistance item normally turns some item into a whatever of resistance +1, but can I also cast it directly on a warforged without having to target a piece of equipment?

Third, does a golem's magic immunity work against infusions (at least those that allow SR)? I don't see a rule that says otherwise, but it just feels wrong somehow. An infusion like disable construct doesn't seem nearly as powerful if the most powerful constructs are immune to it.

First, do infusions suffer arcane spell failure?

Based on the fact that Artificers get light armor proficiency, I'm guessing no; note that all classes which suffer ASF have proficiency with no armor. Because they are not listed as having ASF, then the negative probably holds true.

Second, the description of infusions says they can be applied to an item or construct. That means any infusion, right?

To my knowledge, yes. I visually see it as casting it on their armor, since a Warforged is armor, so to speak, but the rules state that the warforged can have infusions cast on them, so they count for all infusions.

Third, does a golem's magic immunity work against infusions (at least those that allow SR)?

I assume yes, because we are not given evidence to the contrary; Infusions are spell or spell life abilities, they can be disrupted and so forth, plus, I think (don't have it with me now) the Artificer Infusions entry says that they can be nullified in an anti-magic field, so yes, for this purpose, they are spells. Note this does not make them useless, because MANY constructs do not have spell resistance or immunities.
