ActiveLockExists

The object or state already exists; treat the goal as met or pick a different target

The destination coldkey already holds a lock with nonzero locked mass on that subnet, so a new or transferred lock cannot be created there. Inspect the Lock storage for the (coldkey, netuid, hotkey) triple and wait for the existing lock to unlock or remove it first.

Declared by the SubtensorModule pallet; it classifies to the semantic code already_exists.
