You are ducking the issue.
My objection is it is not difficult to build Non-trap Traps whose constituents parts are all unambiguously non-traps by your definitions.
I think you are overstating the case just a tad.
Look at my example again. It walks like a trap. It talks like a trap. If it is not a trap, something is wrong with the definitions you are using.
No it's not a trap. It hinges on something that is specifically not a trap: A guard creature of some sort waiting to respond to an alarm. Sounds like a standard D&D encounter to me. There are multiple ways of disabling or avoiding the alarm, the disable device skill just isn't one of them in this instance, since there is no device or magical writings to disable.
The alarm spell only reveals the presence of the characters. Nothing else. It doesn't catch them, impede their progress, or cause them any damage. Whoever or whatever responds to the alarm does that.
If the zombie is going to react to the alarm, then at that point it's a combat situation and you roll initiative.
If the zombie triggers some mythical "non trap anti-personel device" that you never defined, then that's your problem. That's a straw man arguement on your part, since I haven't been talking about anything like that. That's not me ducking the issue, that you trying to turn it into something else.
I've just been talking about the alarm spell, and about the difference between an alarm and a trap. One alerts people to your presence, the other does something to you when you trigger it.
