Configure the source system
The System Source card is where every analysis begins — it anchors the pipeline to the code you want to examine. It can point at a single repository, import an entire GitHub organization, or accept CSV metadata when you already have the system details on hand.
System Source supports manual entry, organization import, branch selection, commit selection, and CSV upload. Choosing a specific branch and commit pins the whole pipeline to one version, so every piece of evidence you produce maps back to an exact point in your release history. Once the selection is confirmed, Generate IR can consume the card directly.
