OpenAlex indexes TSE ~2-3 months late (nothing after 2026-06-26 as of Sep 2),
so TSE never appeared in weekly digests. Sources can now be flagged
crossref_fresh: their recent papers are discovered via Crossref (created-date
window, paper-level CC licence = OA) and listed without abstracts; a digested
paper's missing abstract is filled once OpenAlex indexes the DOI, so a later
--force re-run can add its per-paper summary.
