Yesterday's Poople answer
While #411 PAIN was still the live board, the previous puzzle was #410, FOES, on September 28, 2026. One shortest path is FOES → DOES → DOER → DOOR → POOR → POOP.
I checked this against the published #410 write-up. The line FOES → DOES → DOER → DOOR → POOR → POOP is the one both the alphabetical search and that write-up show.
