SortedContainerWriter::addAlreadySorted updates its checksum calculator outside the rollback handler. When the enclosing writeConflictRetry retries a batch, the failed attempt's checksum contributions are kept and re-added on retry, so the recorded _originalChecksum }}over-counts. A later read-back through {{ContainerIterator fasserts in _compareChecksums }}with {{ChecksumMismatch (fassert 11605900) when there are WCE during a PDIB.
