What you're saying sounds reasonable, but it completely avoids the question I asked about what point in the process it stopped being food by only mentioning the first and last steps. I'd argue that in order for a boundary to be clear, there needs to be specific step in the discrete process where the output of that step isn't considered food anymore. I honestly can't tell if you're saying that I personally can't see the boundary but you are able to, or if you're using "you" generically when you say "you cannot see", but if you mean the former, I don't think it's particularly helpful to assert that you know what it is without explaining further, and if you mean the latter, I don't think I agree with you on what constitutes a boundary being "clear".
