Dependency graph

Nothing to draw. Its statement rests on no other declaration in this project, and names nothing from a package left unaudited โ€” so the graph is this declaration alone. That is the answer, not a missing picture.

Audit surface: 0 project declarations, 3 external constants

This is the tool's own reading of one build's recorded axioms, and it is not robust against an author who wants it to pass. Checking meant to be relied on should go through Comparator, which replays the proof through the kernel from an export against an explicit list of permitted axioms.
