Questions
Does it change or upload anything?
No. It reads supplied local evidence and writes only to the selected output directory.
Is this an AI judgment?
No. The packaged checker is deterministic and applies documented rules to the supplied input.
What does a ready result mean?
It means no automated finding was produced. The responsible owner still reviews the original source and decides what to do.
How does malformed input behave?
Invalid JSON, duplicate identifiers, missing required arrays, and invalid core values fail closed.
Can I audit the result?
Yes. Every finding carries a stable code, record identifier, severity, source, and message.
