Raman turnover record v2.0: synthetic corpus, evaluation records and environment behind the nanocrystalline-graphite crystallite-size turnover preprint

Data record behind Resolving the Raman crystallite size turnover in nanocrystalline graphite with a synthetic benchmark (R. J. York, preprint v2.0, 2026-09-05): the deterministic synthetic corpus (mac_synthetic_v2.npz, 3,400 spectra, seed 3407), per-row metadata, the physics manifest, the three evaluation records (revisions 2, 2.1 and 3), the probe readings, the Ed25519 operator public key of the platform ledger, the pinned environment, the preprint PDF and its LaTeX source, and the record README. Every file is published with the same SHA-256 digest at https://ryanjamesyork.com/raman-turnover. The code that generates the corpus and re-derives every reported number is released separately (github.com/SSX360/raman-turnover-benchmark, release v2.0, Apache-2.0). All results are modelled: outputs of a declared forward model; no physical film is represented.

It was the LaTeX source of the preprint and carried, in TeX comments, the author’s working notes and a street address that were not meant for deposit; its digest above is left as a record of what the version contained. The cleaned source, the four figures as vector files and the same nine data files are in version 2.1 of this record (10.5281/zenodo.22734180), which supersedes this version.
