Constraint violations report for companion of (Discussion, uses, items, changes, related properties): two or more astronomic bodies of the same type relating to each other

Data time stamp: 6 May 2026, 03:27 (UTC) — Items processed: 3,699

The report is generated based on the settings on Property:P399#P2302.

Updates overwrite this page. Some may already be fixed since the last update: check RecentChangesLinked.

When incremental dumps and the bot work as planned, items fixed before 07:00 UTC disappear in the next update. The report is not updated if only the item count changes.

The report can include false positives. There is no need to "fix" them.
