# Schemas
마이크 배열, scene, experiment, result의 versioned JSON Schema를 둡니다.
JSON Schema Draft 2020-12 형식입니다.
- `array.schema.json`: 배열 크기, 좌표계, 마이크 위치와 선택적 보정값
- `scene.schema.json`: 재현 가능한 음원 recipe, asset 참조와 ground-truth 위치
- `experiment.schema.json`: scan plane/grid, 주파수 대역, STFT와 DAS 설정
- `result.schema.json`: 실행 환경, timing, peak와 평가 지표 요약
중복 id, Nyquist, 시간 구간과 참조 무결성은 `packages/contracts/validation.js`에서 추가로 검증합니다.
