Agree this is a risk and also think it's probably small, but it's hard to say. I think the $ anchoring the regex is probably safe enough. As noted earlier, this tracks with what kunit.py already does. That was necessitated by dynamic prefixes such as timestamps, etc. So I think this is probably a fine risk to take. I imagine we could add constraints of prefix string, e.g. must have [] around it, etc. if we want to try and minimize this risk. But I don't know if it's necessarily worth it, given what we know right now. Along those lines, I think I like this approach (Alternative 1) more than Alternative 2/2b. I'm not sure we need a structured way to specify metadata in KTAP yet? The prefix seems like a reasonable candidate, but do others have ideas of other bits of metadata we'd want to be able to declare? Daniel
