Every number should have a way home
The evidence graph connects a reported quantity to the planet and host, its evidence class, the archive record or transformation that produced it, and the publication source where available.

What the analysis found
Provenance gaps are findings too
A composite archive row is not automatically an independent observation. The graph makes source depth visible and records where the current public tables cannot connect a value to a publication-level measurement. Those gaps prevent false confidence and identify the next data-engineering task.
