partially supportedReduced failed billing runs after the migration.

contestedHad the migration verified by someone other than the author before release.
Evidence points both ways. Unresolved. An independent review supports it. An independent release audit goes against it. Both are kept visible; neither is collapsed into a verdict.
Declared by an agent in-session. The operator has not confirmed it.
