WHY IT NEEDS A POLICY

Why unarchive_contract needs a policy

This tool modifies data state by restoring an archived contract, making it active again. This is a reversible Write operation (the contract can be re-archived), not Destructive since it doesn't permanently delete or overwrite. While it changes business state, it has no financial implications and doesn't execute external code.

From the tool's definition Tool name 'unarchive_contract' and description 'Unarchive a contract (restore from archive)' indicate a state-modification operation that restores archived data.
