Define the nine JSON Schemas (draft 2020-12) exchanged between compiler stages
per MASTER_SPEC §10–§11, plus a reusable validation helper.
Schemas (schemas/json/, cross-referenced by $id):
- scene, character, concept, interaction, metadata, knowledge_base_entry,
resolved_tag, category_map, prompt_output
- Scene requires all seven sections (collections may be empty); Concept is a
bare string or an object with required name; Character has an integer id plus
seven concept arrays; Interaction has integer participants and a concept.
- Each schema carries a major.minor version; unknown fields rejected by default.
Helper (schemas/validation.py):
- validate_document(doc, schema_name, *, allow_unknown=False) -> list of
structured ValidationIssue (empty = valid); collects all errors.
- Loads all schemas into a referencing registry so cross-schema $ref resolves.
- allow_unknown relaxes additionalProperties per config without duplicating
schemas (schema-valued additionalProperties, e.g. Category Map, is preserved).
Tests: valid + several invalid documents per schema, unknown-field toggle,
unknown-schema error (34 assertions). Bumps jsonschema to >=4.18 for referencing.
