## STRUCT-001 — JSON Schema Definition ✅

**Completed:** 2026-02-18  
**Scope:** Define JSON schemas for the v2 multi-file project format

### What was built

All files live under `packages/noodl-editor/src/editor/src/schemas/`:

#### Schema files (8 total)

| File | Schema ID | Describes |
|------|-----------|-----------|
| `project-v2.schema.json` | `https://opennoodl.dev/schemas/project-v2.json` | Root project metadata (`nodegx.project.json`) |
| `component.schema.json` | `https://opennoodl.dev/schemas/component-v2.json` | Component metadata (`component.json`) |
| `nodes.schema.json` | `https://opennoodl.dev/schemas/nodes-v2.json` | Node graph definitions (`nodes.json`) |
| `connections.schema.json` | `https://opennoodl.dev/schemas/connections-v2.json` | Connection/wire definitions (`connections.json`) |
| `registry.schema.json` | `https://opennoodl.dev/schemas/registry-v2.json` | Component index (`_registry.json`) |
| `routes.schema.json` | `https://opennoodl.dev/schemas/routes-v2.json` | URL route definitions (`nodegx.routes.json`) |
| `styles.schema.json` | `https://opennoodl.dev/schemas/styles-v2.json` | Global styles + variants (`nodegx.styles.json`) |
| `model.schema.json` | `https://opennoodl.dev/schemas/model-v2.json` | Backend data model definitions (`models/<Name>.json`) |

#### Validator (`validator.ts`)

- `SchemaValidator` singleton class — compiles all 8 schemas once, reuses validators
- `SCHEMA_IDS` const — typed schema ID map
- `validateSchema()` convenience function
- `validateOrThrow()` — throws with context on failure
- Per-schema convenience methods: `validateProject()`, `validateComponent()`, etc.
- `formatValidationErrors()` — human-readable error formatting
- Ajv v8 with `ajv-formats` for `date-time` format validation
- `allErrors: true` — collects all errors, not just first

#### Index (`index.ts`)

- Re-exports all schemas, validator, and TypeScript interfaces
- Full TS interfaces for all 8 file types: `ProjectV2File`, `ComponentV2File`, `NodesV2File`, `ConnectionsV2File`, `RegistryV2File`, `RoutesV2File`, `StylesV2File`, `ModelV2File`

#### Tests (`tests/schemas/schema-validator.test.ts`)

- 33 test cases covering all 8 schemas
- Valid minimal fixtures, full fixtures with all optional fields
- Invalid cases: missing required fields, wrong enum values, invalid formats
- Edge cases: legacy component refs (`/#Header`), complex port type objects, deeply nested metadata
- Registered in `tests/index.ts` → `tests/schemas/index.ts`

### Dependencies added

```json
"ajv": "^8.x",
"ajv-formats": "^2.x"
```

Added to `packages/noodl-editor/package.json` dependencies.

### Key design decisions

1. **`additionalProperties: true` on nodes/connections** — node parameters and connection metadata are open-ended by design; the schema validates structure, not content
2. **Port type is `oneOf [string, object]`** — Noodl uses both `"string"` and `{ name: "stringlist", ... }` type formats
3. **`strict: false` on Ajv** — schemas use `description` in `definitions` which Ajv strict mode rejects
4. **`require()` for `ajv-formats`** — avoids TS type conflict between root-level `ajv-formats` (which bundles its own Ajv) and the package-local Ajv v8

### Verification

```
33/33 smoke tests passed (node smoke-test-schemas.js)
0 TypeScript errors
```

## Next: STRUCT-002 — Export Engine Core

**Unblocked by:** STRUCT-001 ✅  
**Goal:** Build the engine that converts the legacy `project.json` format into the v2 multi-file directory structure, using the schemas defined in STRUCT-001 for validation.
