Narrative

{principal.name} can remove Shield Advanced DDoS protection from {protection.name} (shield:DeleteProtection), reducing DDoS coverage on the resource. This lowers resilience to volumetric attacks but does not grant access to protected data. This is a cover-tracks / weaken-defenses action, not an access grant.
