non-goal.duplicate

You added a constraint whose bold lead was already on the list, most often after a merge kept both sides or because nobody read the list before proposing.

What it means

Two bullets lead the same way: the later goes and the first stays, which is where the reader already found it.

One command closes it, and it is derived rather than composed.
