arkhelang (Python)

The Python reference implementation of Arkhe, an ontology language for AI systems. See the repository root for the language itself.

Currently provides the v0.1 validator:

pip install arkhelang
arkhe validate path/to/module.arkhe.yaml

Validation is two layers: structural (the published JSON Schema) and semantic (name resolution, lifecycle-state rules, effect reach and cardinality, CEL guard analysis with the two-hop traversal bound). Exit codes: 0 valid, 1 invalid, 2 unreadable input. --json emits findings as machine-readable output. akl is installed as an alias of arkhe.

The conformance fixtures in the repository's fixtures/ directory are the specification of this tool's behaviour; pytest runs them.
