Enabling object locking on a bucket comes down to storing the x-object-lock-meta-status and optionally x-object-lock-meta-default headers on the bucket context object. This immediately takes care of caching caches the bucket’s object locking configuration in memory so it is readily available during object requests.

Gateway checks if the object is locked when it gets a HTTP 403 Forbidden error from Swarm. Gateway simulates the S3 behavior creating a new (unlocked) object version, immediately followed by a DELETE, thus creating a delete marker.
For SCSP, use a configuration flag to pick the desired behavior:
