Do you suspect a confident hallucination? This is a flight data recorder for AI. It helps you reproduce everything the model just did.
You are allowed to read the card first:
curl -fsSL https://npvg.org | less
Then run it:
curl -fsSL https://npvg.org | bash
This address serves a page to a browser and a script to a terminal. Nothing hides in the difference: the script is the first command above, and the second runs it.
What it installs is a reproducible workshop pinned with Nix. Take a reading. Change one thing. Take the reading again. The difference is the receipt.
