New: scholarly safety checks Two new right-click context-menu items and matching popup buttons:

Check retraction with Scholar Sidekick — checks the selected DOI / PMID / arXiv ID against Crossref and Retraction Watch.
Check open access with Scholar Sidekick — checks Unpaywall and surfaces the best legal open-access copy when one exists.

New: bundled safety checks in the cite flow A new "Include safety checks (retraction + open access)" toggle in the popup. When on, the standard Cite action returns the formatted citation alongside its retraction status and open-access status in one round trip — useful when you want to know about both before pasting a citation into a manuscript. New: one-click handoff to the website citation verifier A "Verify ↗" button in the popup opens the website's full citation verifier (/tools/citation-verifier) with your selection already parsed into the form — title, DOI, year, and first author pre-filled where the parser can pick them out. No more pasting the citation a second time. Improved: clearer error messages When an upstream resolver (arXiv, PubMed, …) times out or returns an error while looking up a non-DOI identifier, the popup now says "Upstream resolver timed out. Try again in a moment." instead of misleadingly reporting "No DOI resolved" for what was actually a transient network issue. Permissions No new permissions. The extension still uses only contextMenus and storage, and only ever contacts https://scholar-sidekick.com. Full privacy policy: https://scholar-sidekick.com/legal/privacy
