Core data coverage: 50%

8 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.

Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.
