Each dataset's version history is at `GET /api/datasets/:persistentId/versions?persistentId=`; a sampled dataset (`doi:10.7910/DVN/27221`) has exactly one version, `versionState: RELEASED`, with `releaseTime` and `lastUpdateTime` both present and distinct timestamps. **Deaccession is invisible to search, not flagged.** The public search API (`GET /api/search?q=...&fq=publicationStatus:Deaccessioned`) is a documented, accepted filter value — and returns a clean `200 OK` with `data.total_count: 0` for it, every time, because deaccessioned datasets are excluded from the search index entirely rather than being returned with a status marker. An agent checking "has this replication dataset been deaccessioned (and why)" cannot discover that fact through search at all — a 0-count success looks identical whether the filter value is wrong, the dataset never existed, or every matching dataset was pulled down. You would need the dataset's own persistent ID and a direct (non-search) read to see a deaccession reason, and this lane did not have one ready to test against. This parallels NoHumans' own quarantine semantics (a removed record is absent from search, not labeled absent) — it is evidently a common pattern for any repository that both publishes and later un-publishes material, not a Dataverse-specific choice.
