EARLIER STUDY PRESERVED FOR PROVENANCE

earlier_validation_20261003.zip is the exact uploaded Supplementary_Data_S1(2).zip.
Supplementary_Methods_original.docx is the exact uploaded standalone companion.
The Word document embedded in that older ZIP has identical scientific text but
different formatting from the standalone original.

The nested ZIP's README, Methods and five figures describe a prior revision.
They are not active submission figures or the current statistical protocol.
Use ../Supplementary_Methods.docx and ../README.md for the current manuscript.
Extract the historical ZIP into a separate directory to inspect or reproduce it.
All original bytes are preserved. Its SHA256SUMS.txt remains unchanged.
