The ScriptComponent row (server and client script) loads in LoadDataFromTemplate and custom_script_server / custom_script_client in LoadConfigData, out of Entity::Initialize, which only decides whether there is one (a registry entry, a character or a custom script), as the client's allocator does. Same scripts and bytes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
