"""Change C5 (Gitea issue 31): filing is blocked, not warned, while VISUAL still shows a work order open, on both
routes. On a VISUAL packet the feed is the one writer of `vclosed`: it sets it when it sees every work order closed
(the Clerical board then shows the packet under "Ready for data book") and clears it when one shows open again.

The feed's observe step runs here on legs written by SQL. Nothing here reads VISUAL or M-Files."""
