Which report formats?
HTML, PDF, DOCX and Markdown. HTML and Markdown come from the report engine; PDF and DOCX are written directly from the same report payload source, so every format has the same sections.
What goes in a report?
Site information, missions, datasets, findings and measurements from the open project. Alongside the report a processing run writes machine-readable files: measurements, volumes, risk scoring and asset health, each as JSON outputs list.

What does a report say when there is nothing to report?
It says so. The Aukerman report recorded no findings and states that this is not evidence the asset is free of defects. When measurements are absent the report says they are absent rather than printing zeros source.
