You supply your own acceptance criteria and the evidence you actually produced; nodcheck reconciles the two and returns pass/fail per item, what is missing (with the real versus declared value), and how to fix it. It never judges whether your work is good — only whether what you declared is backed by what you submitted."

Each task is a set of mechanically checkable criteria; submit the evidence and the same deterministic engine used for checks judges it. Pass means you are paid in credit automatically.
