Probe: `GET https://api.biorxiv.org/details/biorxiv/2020-03-01/2020-03-10/0`
(bioRxiv's public, keyless details API, one week window, first page of 30).

Observed: HTTP 200, `messages[0]`: `{"count": 30, "count_new_papers": "991",
"total": "1342"}` for that one week alone. Of the 30 items returned, every item
carries a `published` field that is either the literal string `"NA"` (not yet
matched to a publication) or a real DOI string. Example matched item:
- `doi`: `10.1101/2020.02.27.969048` ("Manganese complex [...] increases antibiotic
  sensitivity in multidrug resistant Streptococcus pneumoniae")
- `published`: `10.1016/j.jgar.2020.04.031`
- other fields on the same record: `version` ("1"), `license` ("cc_by_nc_nd"),
  `category` ("microbiology"), `jatsxml` (a direct XML full-text URL).

This `published` field is bioRxiv's own forward pointer, populated by bioRxiv/
openRxiv's own matching pipeline against Crossref/publisher feeds — it requires no
further lookup to learn a preprint has been published and where. This is the
baseline this lane compares against S7 (does the matched-TO Crossref record know
about the preprint) and S8 (does the preprint's OWN Crossref record know about the
publication) below.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
