 entities and phenomena required in special containment procedures are assigned in object class for purposes of research priority, budgeting, and other considerations. The class assigned to an object is generally determined by a number of factors, but most importantly by a combination of its difficulty to contain, as well as the danger posed to Foundation personnel and humanity at large. A particular anomaly's classification is subject to update and modification as research and our understanding of the object entity or phenomena improves. Primary Classes These are the most common object classes assigned to anomalies and make up the bulk of the Foundation's database. Safe Safe class objects are those anomalies that are either sufficiently understood that they are now completely and reliably contained on a permanent basis or otherwise do not trigger their anomalous effects unless intentionally activated. Classifying an anomaly as safe however does not mean that handling or activating it does not pose a threat, and personnel to be reminded that all special containment procedures and safety protocols are to be observed at all times. Euclid Euclid class objects are anomalies that are either insufficiently understood or inherently unpredictable such that reliable containment is not always possible but do not pose sufficient threat to qualify for keter classification. The vast majority of anomalies cataloged and contained by the Foundation are initially classified as euclid until they are either sufficiently understood or exhibit sufficient danger to requalify reclassification. In particular, any anomaly that exhibits ectonymy, sentience, and or sapience is generally classified as euclid class entity at minimum due to the inherent unpredictability of an object that can act or think on its own. Keter Keter class objects are anomalies that pose a mimical threat to the safety of Foundation personnel, and the rest of mankind need to require extensive and complex procedures to contain or cannot be fully contained by the Foundation's current technology and knowledge. These anomalies are generally considered the most dangerous ones in Foundation's containment and all research efforts are directed towards enabling more reliable containment of such anomalies or as a last resort, the timely neutralization or destruction of anomalous effects. Secondary classes The following object classes are subclasses that supplement the object's primary or former classification. Neutralized Neutralized anomalies are those that are no longer anomalous either through having been intentionally or accidentally destroyed, disabled, or otherwise no longer function or exhibit anomalous effects. The documentation for neutralized anomalies is archived for posterity in case the anomaly regains its anomalous properties or otherwise recurs in the future. Explained Anomalies are those that are completely and fully understood to the point where their effects are now explainable while mainstreamed science have been debunked at the falls for mistaking classification or are so widespread and publicly disseminated such that containment is no longer possible. Esoteric classes The following object classes fall outside of the purview of standard classification. Domual Domual class objects are highly classified in extremely rare anomalies that are utilized by the foundation to contain or counteract the effects of other highly-adangered anomalies, especially keyer class objects. Even the mere existence of domual class objects is classified at the highest level to the foundation and their locations, functions, and current status are known to few foundation personnel outside of the whole five councils.
