WHY IT NEEDS A POLICY

Why link_task_git_trace needs a policy

This tool creates an association (link) between a task and git context data. It writes/creates metadata relating a task to git artifacts. It does not execute code, delete data, or involve financial operations. The action is reversible (links can be removed), placing it firmly in the Write category.
