ResultCodes

The aggregate's lane on the executor is full, so the command was not taken; it may be retried.

Concurrent writers kept winning the version slot; retrying with the same request id is safe.

The command's handling threw an unexpected error (a bug in a decide function or an after hook, a missing dependency): it committed nothing, and a retry fails the same way until the service is fixed.

The node is shutting down, so the command was not taken; another node may take it.

The node is on standby until a migration's cut-over, so the command was not taken.

A command a schedule sent arrived longer before its due time, on the target node's clock, than the node waits for one (wow.timers.max-early-wait): the firing node's clock is ahead. It was not decided; sending it again later with the same request id is safe.

A store the command needed could not be reached or did not answer in time (me.ahoo.wow.spi.StorageUnavailableException); retrying with the same request id is safe.

A subscription on the chain parked the aggregate: the hop will not be reached until it is retried.

The command's handling produced an event its decide function or an after hook does not declare: a bug in the model, named by the message; it committed nothing.

Whether the command committed is unknown; retrying with the same request id is safe.

The wait plan is not a chain the runtime can follow, so the command was not executed.

The wait ran out of time. It says only that the wait gave up, not that the command failed.
