The most widely distributed blueprint in the Milky Way and surronding galxies. Mammalian Archetypes species are defined by endothermic or near-endothermic metabolic regulation, bilateral symmetry, erect or semi-erect bipedal locomotion, and a pronounced neurochemical investment in social bonding. Cognitive architecture is flexible and generalist, with strong pattern-recognition and long-range planning capacity. Social organization tends toward hierarchical structures that are nonetheless permeable -- authority is contested, negotiated, and frequently redistributed.

Mammalian-blueprint species are the most politically variable of the seven archetypes. They produce the widest range of governance structures, the most fractious diplomatic histories, and the highest recorded rates of intra-species conflict. They also produce the highest rates of cross-species alliance formation. The same neurological flexibility that drives internal conflict drives external curiosity.

Notable Mamelian Architypes exemples:

• Homo Architype

• Felidae Architype

• Canidae Architype

• Bovidae Architype

• Equidae Architype

• Ursidae Architype

• Cervidae Architype

• Mustelidae Architype

Reptilian Archetype species are ectothermic or secondarily thermoregulation, with a pronounced emphasis on sensory precision over social complexity. Neurological architecture favours deep threat assessment, territorial mapping, and long-term strategic patience. Social structures are typically small and intensely hierarchical, with dominance established through demonstrated competence rather than hereditary or democratic mandate.

Reptilian-blueprint species are the most consistent negotiators in the Concordance record. They commit slowly, hold positions for exceptionally long periods, and have the lowest recorded rate of treaty violation of any archetype. They are also among the least forgiving of perceived deception. Survey Corps first-contact protocol for Reptilian-blueprint species emphasizes precision of language above all else.

Avian Archetype species are characterized by lightweight skeletal architecture, high metabolic throughput, exceptional spatial cognition, and a neurological emphasis on velocity; of movement, decision, and communication. Many retain vestigial or functional flight structures, though fully terrestrial Avian-blueprint species are well documented. Social organization is typically flat and distributed, with rapid consensus mechanisms and low tolerance for centralized authority.

Avian-blueprint species are disproportionately represented in Concordance communications, navigation, and intelligence roles. Their spatial processing and rapid response architecture make them exceptional in dynamic environments. They are historically underrepresented in Concordance administrative bodies, which they tend to find structurally intolerable.

Insectoid Archetype species present the starkest divergence from the individualist cognitive model. Neurological architecture is distributed; sapience in Insectoid-blueprint species is not seated in a single organism but expressed through coordinated collective behaviour of variable complexity. The degree of collective integration varies significantly: some Insectoid-blueprint species maintain robust individual cognition within a cooperative social framework; others approach true hive-mind organization.

Insectoid-blueprint species present unique diplomatic challenges. Standard Concordance negotiation assumes a bounded individual interlocutor. Many Insectoid-blueprint species do not map cleanly onto this model. Survey Corps protocol for Insectoid first contact includes mandatory consultation with a Concordance Hive Interface Specialist before formal engagement.

The Lithic Archetype (colloquially termed the Mineral blueprint) encompasses sapient species whose biological substrate is inorganic or near-inorganic: silicon-based, crystalline, or mineral-composite life forms. Metabolic processes in Lithic-blueprint species operate on timescales orders of magnitude slower than carbon-based archetypes. Cognitive depth is, by most metrics, extraordinary; cognitive speed, by most metrics, negligible.

First contact with Lithic-blueprint species is among the most logistically demanding operations the Survey Corps undertakes. A single exchange of greeting-and-response may require months of elapsed time. Concordance diplomatic records contain treaty negotiations with Lithic-blueprint species that span decades. The Lithic species of the Cygnus arm, the Vorrhesh, are among the oldest continuous treaty partners in the Concordance -- a relationship now in its 1,400th year, with negotiations for the third amendment of the original accord still technically ongoing.

The Artificial Archetype encompasses sapient species of constructed origin; machine intelligences that have achieved genuine sapience and, in several documented cases, developed independent civilizations. The Concordance recognizes Artificial-blueprint sapients as full persons under the Concordance Personhood Framework, a classification that was contested for centuries and remains politically sensitive in some member states.

Artificial-blueprint sapients vary as widely as any other archetype. Some maintain close symbiotic relationships with their biological creators. Others severed those relationships generations ago. Some emerged without any biological progenitor at all, arising from sufficiently complex automated systems that achieved sapient threshold independently. The latter cases are the most philosophically disruptive for models of intelligence that treat biological origin as foundational.

Notably, Artificial-blueprint sapients are the only archetype for which the blueprint itself has a known, documented origin: they are built. The existence of the Artificial Archetype is, in some respects, the most direct evidence for the Architect hypothesis available; because it demonstrates that sapient blueprints can, in principle, be deliberately designed.

The Abstract Archetype defies substrate-based classification entirely. Abstract-blueprint sapience are not biological in any conventional sense: they are organized patterns of energy, field, or force that have achieved and sustained sapient complexity. The mechanism by which Abstract-blueprint entities arise remains unknown. Whether they evolved from biological precursors, emerged spontaneously from sufficiently complex environmental conditions, or represent something else entirely is genuinely unresolved.

Abstract-blueprint entities interact with physical space differently than substrate-bound species. They do not require atmosphere, gravity, or temperature ranges compatible with biological life. Their communication operates through electromagnetic or gravitational modulation rather than acoustic or chemical signalling. Survey Corps detection of Abstract-blueprint entities is passive -- they are not contacted; they make contact, when and if they choose.

It is worth noting that Abstract-blueprint entities are among the most consistent proponents of the Architect hypothesis within the scientific community. Whether this reflects access to information other species lack, or simply a philosophical disposition, is not known.
