    WrongParent,
    StaleBefore,
    InvalidBackfill,
    RevisionTargetMismatch,
    ProgramTargetMismatch,
    IncompleteOperationCoverage,
    AuthoredOperationRequired,

}

Failure to prove a migration program.

Variants

WrongParent

A revision does not name the preceding revision.

StaleBefore

An operation does not consume the current simulated schema.

InvalidBackfill

A backfill was admitted against a different schema.

RevisionTargetMismatch

A revision does not produce its declared target.

ProgramTargetMismatch

The program does not produce its final target.

IncompleteOperationCoverage

An operation’s claimed edit does not match the before/after snapshots.

AuthoredOperationRequired

The requested automatic diff is destructive, narrowing, or ambiguous.

Identity

Schema identity could not be calculated.
