## Why cancel_order is rated Critical

Cancelling an order is a destructive operation because it permanently terminates an active trading instruction. While not directly moving money like Financial tools, it irreversibly modifies the state of a financial position by removing an open order. This falls into Destructive (irreversibly deletes or overwrites data) rather than Write (reversible modifications).

## Use case
