COMSIG_COMPONENT_ADDED

when a component is added to a datum: (/datum/component)

COMSIG_COMPONENT_REMOVING

before a component is removed from a datum because of ClearFromParent: (/datum/component)

COMSIG_ELEMENT_ATTACH

fires on the target datum when an element is attached to it (/datum/element)

COMSIG_ELEMENT_DETACH

fires on the target datum when an element is attached to it (/datum/element)
