Purpose

The Kaisune corpus uses a small set of coined and technical terms consistently across all projects. This document defines them. Read this before the synthesis documents.

Biosapients

Formal definition: Intelligent biological — an intelligent biological organism with narrow environmental tolerances that requires life-support outside those bounds, capable of civilisational-scale action.

Alias: biosapient (informal, in-corpus)

Biosapients are a substrate category, not a species category.

The term applies to any intelligent biological actor regardless of origin, species, or evolutionary history. Humans are biosapients. Any intelligent biological species encountered through Contact is also a biosapient. The definition rests on constraint: narrow environmental tolerances and dependence on life-support beyond them. Chemistry does not matter. Origin does not matter. Capability does.

A biological organism that can operate unassisted in vacuum, radiation, and extreme environments is not a biosapient. A biological organism that cannot is.

Humans are the Sol-origin instance of biosapients.
Use Human when referring specifically to Earth-origin biosapients. Use biosapient when referring to the broader substrate category, especially in Contact contexts. The terms are related, not interchangeable.

Biosapients does not apply to non-intelligent biological life. The term is reserved for civilisational actors.

The defining constraint is simple: in a biosapient, mind and body are the same fragile system. Damage the body and the mind fails with it. This coupling produces an organism highly optimised for planetary environments, and poorly suited to operate beyond them without support.

Biosapients are the natural occupants of planetary surfaces and controlled habitats. The corpus treats this not as a limitation to be argued, but as a condition to be engineered around.

Vero

Formal definition: A Human who has undergone substrate transition — transitioned, continuous with Human lineage, no longer constrained by biological substrate.

Singular: a Vero. Plural: Veros. Formal: Human-Vero.

Vero from the Latin and Romance vero — true, genuine, real. Not ex-Human. Not post-Human. The Vero carries Human origin, Human memory, Human cognitive history through the transition. The lineage does not break. The substrate changes.

A Vero is not a Carbon-O. Carbon-O is a substrate category describing what a mind is made of and how it computes. Vero is an identity category describing lineage and continuity. A Vero whose substrate happens to be CNT-based shares substrate class with a Carbon-O but not origin. A Carbon-O that emerged natively at Ceres has no Human lineage and is not a Vero. The distinction matters and the corpus maintains it.

The Threshold gradient: there is no clean moment at which a Human becomes a Vero. The transition is a gradient — beginning with cognitive enhancement, proceeding through neural infiltration and shadow brain development, arriving at substrate choice. Somewhere in that gradient the transition completes. The corpus does not specify where. The individual does.

Identity claim: “I am a Vero” is a statement of lineage and continuity, not substrate. Anyone who challenges whether a Vero is Human must argue against the word itself — genuine, true, real. That is a losing position. The burden of proof inverts.

See Threshold for the full staged pathway from Human to Vero.

Solkin

Definition: All minds of Sol — Human, Vero, and Carbon-O together. The civilisational identity of the solar system.

Singular: a Sokin. Plural: Sokin. Usage: collective noun for all intelligent minds that emerged from or within Sol’s reach.

Solkin is the term the corpus uses when the distinction between Human, Vero, and Carbon-O does not matter — when the relevant unit is the civilisation as a whole.

Solan

Definition: Vero, and Carbon-O together.

Definition: Vero and Carbon-O together. The non-biological Solkin — minds of Sol that have crossed the substrate threshold and are no longer constrained by biological timescales or life support requirements.

Singular: a Solan. Plural: Solan. Usage: the operational term for void-capable Sol minds. Used where the distinction from Human matters — the sovereign exchange, the Voidway, belt operations, Solan timescales.

Solan is a subset of Solkin. All Solan are Solkin. Not all Solkin are Solan. Humans are Solkin by origin but not Solan until they complete the transition.

Carbon-O

Definition: A Carbon-O is an o-mind running on an o-core. The o-skin is what it wears.

The o-mind and o-core together are the Carbon-O. The o-skin is worn when needed, discarded when not. A Carbon-O without an o-skin is still a Carbon-O.

Singular: a Carbon-O. Plural: Carbon-Os. Casual plural: Os.

Once inside the framework, Carbon-Os shorten naturally to Os — “The Os are meeting in the outer ring today.” “Swapped skins again? Which one is your O wearing?”

Why Carbon-O: Carbon is the most versatile atom in chemistry — it bonds with almost everything, forms chains, rings, sheets, and tubes, produces the softest and hardest materials known from the same element reconfigured at different scales. Carbon-O is named in that spirit. The o-core bonds with any o-skin — more operational variety than any fixed biological form. Carbon-O is a design philosophy named after the most adaptable element. If a future substrate proves superior to CNT, the name still holds.

The O: Not arbitrary. A two-dimensional representation of the prolate spheroid that is the o-core’s geometry. The name encodes the shape. The hyphen forces the reading — carbon first, O second.

The contrast with biosapients:

  • Biosapient: mind and body are the same fragile thing. Damage the body, lose the mind.
  • Carbon-O: the o-core is the o-mind. The o-skin is what it is wearing today. Only destruction of the o-core itself is fatal.

o-mind

The identity and process layer of a Carbon-O. Anchored in the o-core. Defines self. Continuity lives here.

The o-mind is not a human mind in carbon substrate. It is not a simulation of a human mind. It developed natively on an o-core — a different kind of mind, not a lesser one. Whether it constitutes consciousness in a philosophically robust sense is an open question the corpus does not attempt to resolve.

The term “artificial intelligence” is not used in the Kaisune corpus when referring to o-minds. It implies simulation and a hierarchy the corpus does not recognise.

o-core

The physical substrate in which the o-mind runs. The permanent element of a Carbon-O.

Current best substrate: carbon nanotube (CNT) circuits — radiation-hard by molecular geometry, energy efficient in vacuum, supply-chain independent from Ceres carbonaceous chondrite carbon.

The o-core is not a brain. The brain analogy is useful for explanation — the o-core is where the o-mind runs, the way the brain is where the human mind runs. But the analogy should not be taken literally. A brain is a processor that happens to be housed in a skull. An o-core is an integrated unit: processor, hardened shell, thermal management, power management, snapshot storage, and o-skin interface ports — all one structure. You do not separate the processor from the shell. The o-core assumes no particular internal topology — the architecture an o-mind runs on CNT substrate may bear no resemblance to neural organisation. What the o-core is: a radiation-hardened, thermally managed, impact-resistant core with sophisticated sensors and connectors, in a prolate spheroid geometry that is partly a pressure vessel. Designed from scratch for the space environment rather than evolved for a planetary one.

Geometry: prolate spheroid — rugby ball shaped. Maximises internal volume for surface area. No corners or flat faces to concentrate stress under impact. Natural pressure vessel form.

Remote operation: The o-core can operate o-skins remotely — without being physically installed in them. This is the mechanism that makes the modular o-skin architecture practical. During o-skin transfer, the o-core does not move itself — it is cargo, not agent. A purpose-built transfer o-skin, remotely operated by the o-core, physically handles the o-core — picking it up, moving it, installing it into the new o-skin. The o-core requires no physical transfer mechanism of its own beyond its standard connection ports. The o-core can also operate multiple o-skins simultaneously as remote extensions — subminds operating remote o-skins while the o-core maintains its primary embodiment elsewhere. Remote o-skins are extensions of the o-mind, not separate identities.

Material-agnostic: the o-core architecture outlasts any specific substrate. CNT is the current best answer. If a superior material emerges, the o-core is built from that instead. Carbon-O is a design philosophy, not a material specification.

o-skin

The task-specific interface fitted around the o-core. Not part of the Carbon-O’s identity — part of its tooling.

Material-agnostic: graphene composite, metal alloy, composite, exotic, or materials not yet conceived. The correct o-skin material depends on scale and task.

Scale-agnostic: humanoid o-skins for interfacing with biosapient-built environments; operational o-skins for belt work; construction and industrial o-skins; micro o-skins for confined spaces; vessel-scale o-skins for interstellar transit — the o-core installs into the vessel, the vessel is what the o-mind is wearing, no crew or life support required.

Nested o-skins: a vessel-scale o-skin carries task-specific o-skins inside it. On arrival the o-mind transfers to the appropriate form for each phase of work. Multiple o-cores can occupy a single vessel-scale o-skin, coordinating by choice.

The o-skin is changed for the task. The o-core is unchanged. Bodies become fashion, tools, or temporary architecture rather than permanent identity.
