Security Ownership Map: Turn Git history into a security map

If the person responsible for the certification module on your team leaves tomorrow, do you know which files will become orphans? The answer from most teams was "not sure." The CODEOWNERS file writes nominal attribution, but git log tells the truth. OpenAI The Security Ownership Map recently released by the internal security team is to quantify the gap between the two. Its idea is not complicated: scan the git history and extract which files everyone touched. Then do two things that traditional security scanners do not do, calculate the bus factor and mark orphan sensitive code, and by the way, hide the ownership between people and code.
