Method note for “Certificate of analysis: which claim does each measurement support?”: use “A percentage without its method and sample linkage cannot…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.
Correction note for “Certificate of analysis: which claim does each measurement support?”: retain the wording beginning “A percentage without its method and sample linkage cannot…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
