# Handoff Report — Split-Screen Editorial Carousel Audit

## Forensic Audit Report

**Work Product**: Codebase modifications for Split-Screen Editorial Carousel
**Profile**: General Project
**Verdict**: CLEAN

### Phase Results
- **Hardcoded output detection**: PASS — No hardcoded test results, expected outputs, or dummy values were found in the modified source files.
- **Facade detection**: PASS — No placeholder or facade implementations were detected; all components and backend handlers contain genuine logic.
- **Pre-populated artifact detection**: PASS — Checked for pre-populated log or verification files; no fabricated logs exist.
- **Type integrity**: PASS — Verified there are no `as any` casts, typescript bypasses (`ts-ignore` / `ts-expect-error`), or workarounds in the modified sections.
- **Schema matching**: PASS — Zod schema validations for `layout` and `imagePosition` are defined in `@homaroma/types` and fully handled by MCP tools, forms, and renderers.
- **Behavioral Verification (Build)**: PASS — Successfully built and compiled all workspaces (`apps/admin`, `apps/spa`, `apps/website`, `apps/mcp-server`) with zero TypeScript errors.

## 1. Observation

### Observation 1: Zod Schema in packages/types/index.ts
In `/home/ti/git/homaroma/packages/types/index.ts`, the Zod schema configuration for the carousel section is defined as follows:
```typescript
375: export const EditorialCarouselSectionPayloadSchema = z.object({
376:   title: LocalizedStringSchema,
377:   backgroundColor: z.string().optional(),
378:   textColor: z.string().optional(),
379:   layout: z.enum(['standard', 'split_screen']).optional(),
380:   imagePosition: z.enum(['left', 'right']).optional(),
381:   slides: z.array(z.object({
382:     category: LocalizedStringSchema,
383:     title: LocalizedStringSchema,
384:     description: LocalizedStringSchema,
385:     imageUrl: z.string().min(1),
386:     buttonText: LocalizedStringSchema.optional(),
387:     buttonLink: z.string().optional(),
388:   })).min(1)
389: });
```

### Observation 2: MCP Tool Config in apps/mcp-server/section-toolkit.ts
In `/home/ti/git/homaroma/apps/mcp-server/section-toolkit.ts`, the metadata and updating config for editorial carousel are fully registered:
```typescript
274:       layout: { type: "string", enum: ["standard", "split_screen"], description: "Layout style of the carousel (standard or split_screen)" },
275:       imagePosition: { type: "string", enum: ["left", "right"], description: "Position of the image relative to text when layout is split_screen (left or right)" },
```
No mock payload validations or mock data hardcoding exist inside the handler:
```typescript
573:       const res = await api.put(`/pages/sections/${params.sectionId}`, {
574:         type: config.sectionType,
575:         payload: mergedPayload
576:       });
```

### Observation 3: React Admin Form in apps/admin/src/components/page-builder/EditorialCarouselForm.tsx
In `/home/ti/git/homaroma/apps/admin/src/components/page-builder/EditorialCarouselForm.tsx`, the layout options are fully bound to inputs:
```tsx
91:           <select
92:             value={editingSection.payload?.layout || 'standard'}
93:             onChange={(e) => setEditingSection({
...
105:           <select
106:             value={editingSection.payload?.imagePosition || 'left'}
107:             disabled={editingSection.payload?.layout !== 'split_screen'}
```

### Observation 4: SPA Rendering in apps/spa/src/components/DynamicEditorialCarousel.tsx
In `/home/ti/git/homaroma/apps/spa/src/components/DynamicEditorialCarousel.tsx`, the rendering checks layout settings and renders standard vs. split screen:
```tsx
76:   const isSplitScreen = payload.layout === 'split_screen';
77:   const imagePosition = payload.imagePosition || 'left';
```
And standard/split_screen logic renders:
```tsx
105:                 {isSplitScreen ? (
106:                   <div className={`group grid grid-cols-1 border border-pop-black/10 bg-night-900 rounded-3xl overflow-hidden shadow-sm transition-all duration-300 hover:border-pop-pink/30 ${
107:                     imagePosition === 'left' ? 'md:grid-cols-[65%_35%]' : 'md:grid-cols-[35%_65%]'
108:                   }`}>
```

### Observation 5: Website Rendering in apps/website/src/components/dynamic/DynamicPageRenderer.tsx
In `/home/ti/git/homaroma/apps/website/src/components/dynamic/DynamicPageRenderer.tsx`, the Next.js/SSR renderer handles the same conditions:
```tsx
405:   const isSplitScreen = payload.layout === 'split_screen'
406:   const imagePosition = typeof payload.imagePosition === 'string' ? payload.imagePosition : 'left'
```

### Observation 6: Successful Builds
1. Admin build output:
   `dist/assets/index-YS9BDHsZ.js   1,731.79 kB │ built in 1.29s`
2. SPA build output:
   `dist/assets/index-DkqpNY8A.js   874.47 kB │ built in 1.35s`
3. Website build output:
   `Compiled successfully in 5.1s. Finished TypeScript in 6.9s`
4. MCP Server check:
   `bunx tsc -p tsconfig.json --noEmit` completed successfully.

## 2. Logic Chain

1. **Genuine Logic**: Observations 4 & 5 demonstrate that the split-screen styling and image positioning are governed dynamically by the payload fields (`payload.layout` and `payload.imagePosition`) that are retrieved from the database, not by mock/hardcoded values. No mock bypasses exist.
2. **Type Integrity**: Verification of modified files shows that no typescript directives (`@ts-ignore` / `@ts-expect-error`) were added, and no type-bypass `as any` casts were used. Type checking passes fully on all apps, verifying standard-compliant types.
3. **Schema Matching**: Zod validation schemas match tool definitions, form controls, and SPA/Website renderers correctly, covering layout options ('standard' / 'split_screen') and imagePosition options ('left' / 'right').
4. **Behavioral Integrity**: Observation 6 confirms that all TypeScript code passes compile-time type verification checks.

---

## 3. Caveats

No caveats. All files have been built and reviewed directly, matching the spec.

---

## 4. Conclusion

The Split-Screen Editorial Carousel implementation is **CLEAN**. There are no integrity violations, no mock/dummy logic, no typescript bypasses, and the Zod schemas match the rendered/validated properties perfectly.

## 5. Verification Method

To independently verify the audit results, run:
```bash
# 1. Run type check on SPA
cd apps/spa && bun run build

# 2. Run type check on Admin
cd apps/admin && bun run build

# 3. Run type check on Website
cd apps/website && bun run build

# 4. Run type check on MCP Server
cd apps/mcp-server && bun run check
```
Inspect files `packages/types/index.ts`, `apps/spa/src/components/DynamicEditorialCarousel.tsx`, `apps/website/src/components/dynamic/DynamicPageRenderer.tsx` to verify standard vs split_screen layout branches.
