## STRUCT-001  JSON Schema Definition COMPLETE

**Completed:** 2026-02-18

### What was built

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

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

- `validator.ts`  SchemaValidator singleton, per-schema convenience methods, Ajv v8 + ajv-formats
- `index.ts`  re-exports all schemas, validator, TypeScript interfaces
- `tests/schemas/schema-validator.test.ts`  33 test cases, all passing

### Key decisions

- `additionalProperties: true` on nodes/connections  open-ended by design
- Port type is `oneOf [string, object]`  Noodl uses both formats
- `strict: false` on Ajv  schemas use `description` in `definitions`
- `require()` for `ajv-formats`  avoids TS type conflict

## STRUCT-002  Export Engine Core COMPLETE

**Completed:** 2026-02-19

### What was built

| File | Purpose |
|------|---------|
| `packages/noodl-editor/src/editor/src/io/ProjectExporter.ts` | Core exporter class + legacy types + helpers |
| `packages/noodl-editor/tests/io/ProjectExporter.test.ts` | 50 unit tests |
| `packages/noodl-editor/tests/io/index.ts` | Test barrel export |

### Architecture

`ProjectExporter` is pure  no filesystem access. Takes `LegacyProject`, returns `ExportResult { files[], stats }`.

Output layout:
```
nodegx.project.json
nodegx.routes.json        (conditional)
nodegx.styles.json        (conditional)
components/
  _registry.json
  Header/
    component.json
    nodes.json
    connections.json
```

### Key decisions

1. Pure/filesystem-agnostic  caller writes files
2. Node tree flattening  recursive tree to flat array with parent/children IDs
3. Styles/routes files conditional  only produced when content exists
4. Legacy `stateParamaters` typo normalised to `stateParameters`
5. Metadata split  styles/routes extracted, rest stays in project file
6. Original legacy path preserved in `component.json` for round-trip fidelity
7. Empty `parameters: {}` omitted from output

## STRUCT-003  Import Engine Core COMPLETE

**Completed:** 2026-02-19

### What was built

| File | Purpose |
|------|---------|
| `packages/noodl-editor/src/editor/src/io/ProjectImporter.ts` | Core importer class + helpers |
| `packages/noodl-editor/tests/io/ProjectImporter.test.ts` | 55 unit tests incl. round-trip |

### Architecture

`ProjectImporter` is pure  no filesystem access. Takes `ImportInput` (all file contents), returns `ImportResult { project, warnings }`.

```
ImportInput {
  project: ProjectV2File        (nodegx.project.json)
  registry: RegistryV2File      (components/_registry.json)
  routes?: RoutesV2File         (nodegx.routes.json)
  styles?: StylesV2File         (nodegx.styles.json)
  components: Record<path, { component, nodes, connections }>
}
```

### Key functions exported

| Function | Purpose |
|----------|---------|
| `unflattenNodes(flat)` | Reconstructs recursive legacy node tree from flat NodeV2 array |
| `toLegacyName(componentFile, registryPath)` | Converts v2 path back to legacy name (uses preserved `path` field) |

### Key decisions

1. Pure/filesystem-agnostic  symmetric with ProjectExporter
2. `unflattenNodes`  two-pass: build map, then wire children in order
3. `toLegacyName`  prefers `component.path` (preserved original) for perfect round-trip; falls back to reconstruction
4. `stateParameters`  `stateParamaters` reversal  restores legacy typo
5. Metadata merge  routes/styles merged back into `project.metadata`
6. Non-fatal warnings  component failures collected, not thrown
7. Round-trip validated  20 round-trip tests covering all data types

### Test coverage (55 tests)

- `unflattenNodes`  11 cases (empty, single, parent-child, deep nesting, order, field restoration)
- `toLegacyName`  4 cases (path field, fallback, root, cloud)
- `ProjectImporter.import()`  20 cases (basic, metadata, variants, components, nodes)
- Round-trip (export  import)  20 cases (all data types, edge cases)

### Cross-branch note for Richard

No shared dependencies with Phase 9/6 work. STRUCT-003 is self-contained in `packages/noodl-editor/src/editor/src/io/` and `packages/noodl-editor/tests/io/`. No cherry-pick needed.

## Decisions and Learnings

- **[2026-02-18]** Ajv v8 + ajv-formats: use `require()` for ajv-formats to avoid TS type conflict with root-level ajv-formats package
- **[2026-02-19]** Legacy `stateParamaters` typo (missing 'e') is real  must be preserved in round-trip. Exporter normalises to `stateParameters`, importer reverses it.
- **[2026-02-19]** `component.path` field is the key to perfect round-trip fidelity  always preserve the original legacy name in the v2 component file
- **[2026-02-19]** `unflattenNodes` needs two passes  first build the node map, then wire children in order using the children ID array
