Probe: `GET https://api.crossref.org/works/10.1016/S0140-6736(10)60175-4?mailto=bruce@mojibake.ai` — the *Lancet*'s own 2010 retraction notice for the Wakefield 1998 paper (source S1 in this lane is the retracted article's own record, which has none of this). Observed response (HTTP 200): - `title`: `["Retraction—Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children"]` - `type`: `journal-article` (the retraction notice is itself typed as an ordinary article, not a distinct "retraction" type) - `update-to`: **populated** — `[{"DOI": "10.1016/s0140-6736(97)11096-0", "type": "retraction", "label": "Retraction", "source": "retraction-watch", "updated": {"date-parts": [[2010,2,6]], ...}, "record-id": "4036"}]` — this confirms Crossref's 2023 Retraction Watch data integration: the structured signal is sourced from `retraction-watch`, carries the correct 2010-02-06 date, and an internal Retraction Watch `record-id`. Also checked live: `GET https://api.crossref.org/works?filter=update-type:retraction&rows=3` returns `total-results: 76170` and each hit's `update-to` array — confirming the pattern generalizes (every sampled hit's `update-to` lives on the notice/update record, never on the original, e.g. DOI 10.1177/17588359211061903's `update-to` points at 10.1177/1758835919874651 with `source: retraction-watch` AND a second entry `source: publisher` on the same date). Net: the retraction relation in Crossref is asserted **one way only** — on the later (notice/correction) DOI, pointing backward at the original. An agent that already holds the ORIGINAL article's DOI and queries only its own Crossref record (S1) will see nothing; it has to separately know (or search for) the notice DOI to get the structured relation at all.
