# Ontology kernel direction

> A small stable metamodel with unbounded, versioned domain extension.

**Status:** Design direction; not implemented in Genesis code.

The kernel should define how to express:

```text theme={null}
Origin
Representation
Observation
SourceStatement
Extraction
Derivation
Evidence
Term
Type
Relation
Role
Context
Time
IdentityReference
Mapping
Resource
Operation
Effect
Capability
Policy
Authority
Mandate
Receipt
Version
Module
```

Domain concepts such as `Product`, `ScientificPaper`, `Flight`, or `FinancialInstrument` belong in separate immutable modules.

## Module layers

```text theme={null}
kernel
→ quantities and common structural modules
→ domain modules
→ source-native origin modules
→ mapping modules
→ instance and source-statement graph
→ learned indexes
```

## Core laws

* Native meaning is never destroyed.
* Claims are not silently promoted into facts.
* Context and time are first-class.
* Identity is scoped and revisable.
* Absence distinguishes unknown, not provided, not applicable, redacted, unresolved, and confirmed absent.
* Contradiction is preserved.
* Mappings are versioned claims with provenance.
* Released versions are immutable.
* Anyone may extend; canon admission remains governed.
* Operational reasoning is bounded.
