I publish a path only when a shortest-path search on the client word graph produces it and the length matches the par stored beside that start word. For #410 and #381 I also compared the line to the public write-up.

Dates for puzzles other than #410 are counted one day at a time from September 28, 2026. #381 falling on August 30, 2026 is the check I use for that calendar. The iOS release date, September 16, 2025, is a separate fact from the App Store lookup. I do not merge those into one origin story.

There is often more than one shortest path. Pages say "one shortest path" and name the alphabetical search order. I do not call that line the only solution.
