pub async fn write(
drive: &DriveClient,
sheets: &SheetsClient,
opts: &WriteOptions,
rules: &[FolderPermissionRule],
) -> WriteOutcomeExpand description
Runs one cell mutation, logging every attempt that isn’t a dry run.
Never returns Err: every failure is a WriteResult variant, so the
caller renders one shape and the log records one shape. Exit code stays 0
regardless, matching ADR-0070 §10 / ADR-0071 §12.
