What evidence does an auditor actually accept?
Records your systems produced while doing the work. Not documents you wrote about the work. A policy says what should happen. A ticket, an approval, a log line, a dated export shows that it did. Auditors sample. They pick items from a population and test those, so your evidence has to be retrievable per item rather than as a summary. Screenshots are accepted, and they are the weakest thing accepted. The strongest evidence is what your infrastructure emits on its own. Nobody chose which examples to keep.
