0 unique publications still link to PubMed because no PDF exists in
cdac-downloads.
0 have a PMCID (PoW-gated; auto-fetcher couldn't pull them).
0 have a DOI (try clicking — your library proxy / browser extension
may route to the publisher's PDF). Save downloads with the
suggested-filename.pdf shown beneath each paper, drop into
the cdac-downloads repo, and the next nightly remap on
bdsp-core.github.io will switch the link automatically.
