OptionalisWhether a command participates in repeat. Default: repeatable unless tagged 'noRepeat'.
OptionalmanagerThe undo manager the transaction records into. When present, a repeatable command sets a
repeatable operation here after it runs, so redo() (our undo port wires Ctrl+Y / F4) repeats
it once the redo stack is empty — Excel's "repeat last action". Omit to disable repeat.
OptionalnotifierBusy spinner + error reporting. Omit for a headless host.
The model's transaction boundary — the command's work runs inside transaction.doBatch(...) so it
groups into a single undo entry.
Options for createTransactionalMiddleware.
