name: Spaced Repetition

# Opens (or refreshes) today's `Spaced Repetition — <Month D, YYYY>` issue from
# the problem issues closed 3 and 7 days ago. No stored state: the script
# recomputes both windows from the tracker's close dates on every run, keyed by
# the ET date in the title, so a re-run rewrites one body instead of stacking
# duplicates and a missed day simply never appears.

on:
  schedule:
    # 10:00 UTC = 06:00 ET while the campaign runs (EDT through Nov 1), 05:00 ET
    # after. No DST guard and no second cron: the issue is keyed by ET calendar
    # date, not by the hour it was created, so the drift is cosmetic.
    - cron: "0 10 * * *"
