WHY IT NEEDS A POLICY

Why archive-cards needs a policy

Archiving cards modifies data state reversibly—archived cards remain in Trello and can be restored, making this a Write operation rather than Destructive. The blast radius is medium because bulk archiving could obscure important workflow information, but the operation is not irreversible.

From the tool's definition Tool name 'archive-cards' and sibling tool 'archive-card' in server description. Server description states the tool 'supports...archiving cards.' Archiving is a reversible operation (cards can be unarchived).
