Why vast_unarchive_channel is rated Medium
The tool modifies existing data (channel status) in a reversible manner. Archiving/unarchiving are standard state changes in campaign management systems. While the action reverses a destructive operation (archive), the unarchive itself is not destructive—it restores data to a previous valid state. This qualifies as Write rather than Destructive.
From the tool's definition Tool name contains 'unarchive' and description states 'Restore an archived VAST channel back to active status'. This reverses a prior archival action, modifying the channel's status from archived to active.
