Activity vocabulary, declaration and bounded projection admission. Lifecycle stays in the engine.

Vis configuration vocabulary and JSON Schema validation.

Canonical content vocabulary and JSON Schema validation.

Loads JSON contract documents and validates them with their same-named JSON Schemas.
`schema/common.json` supplies shared definitions. Raw validators reject values outside
the JSON data model; engine adapters may normalize keyword maps before validation.

Gateway declarations loaded from the validated JSON contract.

Renders the validated built-in gateway contract as OpenAPI 3.1.
Extension routes remain in their extension-owned contracts.

Provider limits vocabulary and report validation from JSON Schema.

Python host operations loaded from the validated JSON contract.

JSON Schema contract for language-tool results.

Language-neutral test selection and result contract, validated by JSON Schema.

Feature-toggle vocabulary and contribution validation from JSON Schema.

View vocabulary and JSON Schema validation.

Canonical value and JSON codecs shared by Core, the gateway and every SDK.

This namespace is a pure deterministic boundary: it performs no transport,
filesystem, process or lifecycle work. Engine EDN becomes total JSON data;
in-process readers receive exactly the shape a remote JSON reader receives.
