One week's arrivals post, held in the publisher's repo, keyed by the ISO week (e.g. 2026-W40). It is both the history and the idempotency guard: a run that finds this week's record posts nothing. ⚠ ONLY THE PUBLISHER'S COPY COUNTS — the index refuses this collection from any other repo, or anybody could stop the week's post by writing their own.
