# Beauty Module Migration Report

**Date:** 2026-07-26  
**Scope:** Migrate Beauty business logic to `frontend/modules/beauty`  
**Routes:** Unchanged — all URLs remain under `/beauty/*` via `app/beauty/`

---

## Executive Summary

The Beauty Business module is the **first completed migration** from legacy `components/beauty/` + scattered `lib/`/`hooks/` files into the formal `modules/beauty/` package. All **98 route pages** and **8 layouts** remain in `app/beauty/` as thin adapters; business logic now lives in the module.

## 1. What Moved

### From → To

| Legacy path | New path | Files |
|-------------|----------|------:|
| `components/beauty/*.tsx` | `modules/beauty/components/` | 4 |
| `components/beauty/pages/*.tsx` | `modules/beauty/pages/` | 9 |
| `components/beauty/design-system/*` | `modules/beauty/design-system/` | 6 |

| `app/beauty/(owner)/**/page.tsx` (inline CRUD) | `modules/beauty/features/owner/*.tsx` | 18 |

**Total module files:** 43 (including README, index barrels)

### Deleted / emptied

- `components/beauty/` — fully removed (0 files remain)

---

## 2. What Stayed in `app/beauty/`

Per migration rules, only Next.js routing artifacts remain:

| Artifact | Count | Role |
|----------|------:|------|
| `page.tsx` | 98 | Thin re-exports to `@/modules/beauty/*` |
| `layout.tsx` | 8 | Portal layouts calling `createPortalLayout()` |
| `loading.tsx` | 0 | (none existed) |
| `error.tsx` | 0 | (none existed) |
| `not-found.tsx` | 0 | (none existed) |

### Layout files (unchanged URLs)

```
app/beauty/layout.tsx
app/beauty/(owner)/layout.tsx
app/beauty/owner/layout.tsx
app/beauty/admin/layout.tsx
app/beauty/customer/layout.tsx
app/beauty/reception/layout.tsx
app/beauty/staff-portal/layout.tsx
app/beauty/site/layout.tsx
```

### Route adapter pattern

**Portal pages (unchanged pattern):**
```tsx
export { CustomerWallet as default } from "@/modules/beauty/pages/customer";
```

**Owner CRUD pages (new thin adapters):**
```tsx
export { default } from "@/modules/beauty/features/owner/organizations";
```

## 4. Import Migration

### New canonical imports

```typescript
import { beautyBusinessApi } from "@/modules/beauty/services/beauty-business-api";
import { createPortalLayout } from "@/modules/beauty/components/createPortalLayout";
import { useBeautyLookups } from "@/modules/beauty/hooks/useBeautyLookups";
import { BEAUTY_PORTALS } from "@/modules/beauty/constants/portals";
import { CustomerDashboard } from "@/modules/beauty/pages/customer";
```

### Deprecated shims (backward compatible)

| Shim | Re-exports |
|------|------------|
| `lib/beauty-business-api.ts` | `@/modules/beauty/services/beauty-business-api` |
| `lib/beauty-portals.ts` | `@/modules/beauty/constants/portals` |
| `hooks/useBeautyLookups.ts` | `@/modules/beauty/hooks/useBeautyLookups` |

**119 files** updated by `scripts/migrate-beauty-imports.mjs`. Zero remaining `@/components/beauty/*` imports in source.

---

## 5. URL Preservation

All beauty URLs are unchanged. Examples:

| URL | Route file | Module export |
|-----|------------|---------------|
| `/beauty/hub` | `app/beauty/hub/page.tsx` | `pages/hub` |
| `/beauty/customer/wallet` | `app/beauty/customer/wallet/page.tsx` | `pages/customer` |
| `/beauty/organizations` | `app/beauty/(owner)/organizations/page.tsx` | `features/owner/organizations` |
| `/beauty/site/book` | `app/beauty/site/book/page.tsx` | `pages/public` |
| `/beauty/admin/analytics` | `app/beauty/admin/analytics/page.tsx` | `pages/admin` |

No `next.config.mjs` redirect changes. No backend modifications.

---

## 6. Tooling Updates

| File | Change |
|------|--------|
| `tsconfig.json` | `@/modules/*` alias (already present) |
| `tailwind.config.ts` | Added `./modules/**/*.{ts,tsx}` to content |
| `.eslintrc.json` | Beauty rules apply to `modules/beauty/**/*` |
| `scripts/validate-architecture.mjs` | Beauty domain = `modules/beauty` |
| `scripts/validate-beauty-imports.mjs` | **New** |
| `scripts/validate-beauty-routes.mjs` | **New** |
| `scripts/validate-beauty-bundle.mjs` | **New** |
| `package.json` | Added `validate:beauty*` scripts |
| `components/ds/Button.tsx` | Added `loading` prop (unblocks build) |

### Validation commands

```bash
npm run typecheck
npm run lint
npm run validate:beauty-imports
npm run validate:beauty-routes
npm run validate:architecture
npm run build
npm run validate:beauty-bundle
# Or all beauty checks:
npm run validate:beauty
```

---

## 7. Boundaries

| Rule | Status |
|------|--------|
| Beauty must not import healthcare/accounting | ✅ Enforced |
| Shared/ds must not import modules/beauty | ✅ Enforced |
| Healthcare/accounting unchanged | ✅ |
| Backend unchanged | ✅ |
| CRM not present | N/A |

---

## 8. Not Migrated (by design)

| Item | Reason |
|------|--------|
| Healthcare | Explicitly out of scope |
| Accounting | Explicitly out of scope |
| `shared/` code | Platform layer — Phase 2 |
| `components/ds/` | Shared design system |
| `lib/beauty-business-nav.ts` | Dead file (0 imports pre-migration) |
| Auth guards, SiteHeader | Platform components |

---

## 9. Follow-up Recommendations

1. **Remove deprecated shims** after confirming no external consumers of `lib/beauty-*` paths
2. **Move BeautyTablePage** to `modules/beauty/tables/` when table abstraction is extracted
3. **Extract owner forms** into `modules/beauty/forms/` if CRUD forms grow further
4. **Apply same pattern to Healthcare** as next module migration
5. **Delete `BeautyBusinessShell.tsx`** after confirming zero imports
