All anomalous objects, entities, and phenomena requiring Special Containment Procedures are
assigned an 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 phenomenon 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 are 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 qualify for reclassification.
In particular, any anomaly that exhibits autonomy, sentience and/or sapience is generally classified
a 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
an inimical threat to the safety of Foundation personnel and the rest of mankind and either
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 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 its anomalous
effects.
Secondary Classes
The following Object Classes are sub-classes 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 Explained anomalies are those that are completely
and fully understood to the point where their effects are now explainable by mainstream
science, have been debunked as a false or mistaken 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.
Thaumiel Thaumiel-class objects are highly classified
and extremely rare anomalies that are utilized by the Foundation to contain or counteract
the effects of other highly dangerous anomalies, especially Keter-class objects.
Even the mere existence of Thaumiel-class objects is classified at the highest levels
of the Foundation and their locations, functions, and current status are known to few Foundation
personnel outside of the O5 Council.
