Claim	C009
Hypothesis	H1

Statement

All four sub-claims are accurate: 21 standards, 82 elements, four stages, published by NAS/IOM.

Status

Current: Supported

Supporting Evidence

Evidence	Summary
SRC01-E01	Report title and publisher confirmed
SRC02-E01	Explicit quote: "21 standards with 82 elements of performance"
SRC02-E02	Four stages confirmed with standard counts per stage
SRC03-E01	National Academies Press listing confirms report

Contradicting Evidence

Evidence	Summary

[No evidence found contradicting any numerical sub-claim.]

Reasoning

H1 is supported by the primary source text hosted on NCBI Bookshelf, which explicitly states "21 standards with 82 elements of performance." The four stages are confirmed with standard counts (8 + 6 + 4 + 3 = 21). The publisher attribution is technically the IOM rather than NAS, but the IOM operates under the National Academies umbrella. H1 is the strongest hypothesis.

Relationship to Other Hypotheses

Mutually exclusive with H3 on numerical counts. Partially overlaps with H2 on the attribution question -- H1 acknowledges the IOM/NAS distinction while maintaining that the claim is substantively accurate.
