WHAT IT DOES

What hydra_reorder_download does on Hydra Bridge

WHY IT NEEDS A POLICY

Why hydra_reorder_download needs a policy

This tool reorganizes/reorders downloads between states (active, queued, paused). It modifies the state of a download entry but does not delete data or execute arbitrary code. The change is reversible — a download can be moved back. This is a Write operation with low severity since misuse only affects download queue ordering.

From the tool's definition Move a download to a different area (hero=active, queue=waiting, paused=stopped)
