OperationSource

OperationSource = readonly Operation[] | Iterable<Operation> | AsyncIterable<Operation>

Operations to submit, in order.

Aggregate commit.apply normalizes and preflights an array as a whole before its first append; iterable input is validated one chunk at a time. The full-duplex commit.applyStreaming path validates every source incrementally, including arrays, because committed response groups may arrive while later input is still being produced.
