4.TSUKEMONO. This one is really strange to me. I can't imagine why a UI bears the meaning of TSUKEMONO, a kind of Japanese pickled vegetable.

1. It's a tree, whose wood is used in the manufacture of barrels for aging whiskey. American oak is also called white oak.
2. It means there is danger of failure of the item or process in question. The item is in danger of breaking down or possibly exploding.
3. Whatever [0] is, none of it has been detected.
4. “A kind of Japanese pickled vegetable” is correct.

Sorry, correction. “Trace of [x] discovered” means a tiny amount of [x] has been detected. (Not “none”)

(It should say “trace OF,” not “trace FOR”)

Depending on context, I could also see “Trace for {0} discovered” meaning:

• That a stack-trace related to the process has been found, or
• That some mark indicating the earlier presence of {0} has been found. (This is close to Tom Sloper's interpretation)

I am thinking that {0} is a tag to be replaced by game code with an actual value or text. Lots of localisation systems support C# like string formatting.
