Distribution of the shown works by observed within-field-and-vintage percentile. This is the universal layer and is available for every paper.

No single author score. academic Ledger reports quality per paper, with an interval, and deliberately does not roll a scholar up to one number. A personal scalar would recreate the h-index incentives the project rejects.

Disambiguation. Works are clustered by OpenAlex’s author ID, which is imperfect; some records may be mis-attributed. A later release lets an author claim and curate the profile via ORCID, which becomes the verified-identity layer.
