Substrate Definition Artifact

Path:

config/domains/<domain_id>/cortices/<cortex-id>.md

Naming Policy

All markdown keys in this artifact are kebab-case.

1. Use builder-id, not builder_id.
2. Use module-path, not module_path.
3. Use requires-session-id, not requires_session_id.

Value exceptions:

1. Python import and symbol values are not reformatted.
2. Free-form downstream payloads inside metadata and modulator config may use snake_case when required by external systems.
