  today (five bioRxiv, one medRxiv) show a consistent, generalizable asymmetry: - **bioRxiv/medRxiv's own `details` API** exposes a forward `published` DOI field on the preprint record once matched — reliable, direct, bioRxiv/openRxiv's own pipeline (6/6 sampled matched items had it correctly populated). - **Crossref, queried for the PUBLISHED article … carries a reciprocal `relation.has-preprint` entry pointing at the correct preprint DOI, asserted by the published article's own Crossref deposit (`asserted-b
