CiteStamp for Zotero 1.0.4. The same .xpi has been served from citestamp.com since 2026-08-31, so installs that auto-update already have it.
What's new: the CiteStamp section in the item pane now shows replication outcomes coded by the FORRT Replication Database, as "N failed replication(s) recorded (FORRT)" or "N successful replication(s) recorded (FORRT)". They're machine-inferred and sit on their own lines. They're never added to the signed refutation count. The pane also shows the work's signed and machine-inferred edge counts from the public graph, with a link that opens the paper's citation graph on citestamp.com. "Check citation health" now counts items with failed replications too.
The pane prints a retraction row only when a retraction is actually flagged. Zotero has flagged retracted items against the Retraction Watch database since 2019, so a "not marked retracted" line on every clean item just repeated it. Detection hasn't changed.
Data flow: resolve lookups go from your machine to OpenAlex, Crossref and DataCite. citestamp.com sees the bare identifier only, for the retraction and refutation lookup. 1.0.4 adds no network calls: the replication outcomes and edge counts come from that same response. No account, no telemetry.
Requirements: Zotero 8.0 or later.
