GraphError

A new checkpoint's parent is not the thread's latest: another writer advanced the thread.

The checkpointer refused or failed a commit; the run stops at its last durable checkpoint. runError is the run's own failure when the commit failed while recording it.

An execution was passed to a graph other than the one that created or restored it.

start was called on a thread whose latest checkpoint is mid-execution; use recover.

A commit is malformed, such as a pending write naming a checkpoint other than the latest.

The builder found one or more structural problems; every problem is listed.

A node returned a route this graph cannot schedule.

A node returned a failure or threw.

recover was called on a thread with no incomplete execution.

Events before earliestSeq were compacted away and cannot be replayed.

A snapshot does not match this compiled graph; every problem is listed.

A key's update function rejected an update.

The run reached its superstep limit with work still scheduled.

A node emitted an update for a key outside its declared write set.

A key was read or written that the graph did not register, or another key shares its id.

The graph went quiescent while a join still waited for arrivals that nothing can produce.

A checkpoint was written in a format this build does not read.
