+# Batch 1 Status - WHMCS Service Files
+
+## What Was Done
+Fixed 8 files to import from specific domains instead of bare `@customer-portal/domain`:
+
+1. ✅ `whmcs.service.ts` - Split imports to billing/subscriptions/payments/common
+2. ✅ `whmcs-invoice.service.ts` - Now imports from billing
+3. ✅ `whmcs-subscription.service.ts` - Now imports from subscriptions
+4. ✅ `whmcs-payment.service.ts` - Now imports from payments  
+5. ✅ `whmcs-transformer-orchestrator.service.ts` - Split imports
+6. ✅ `whmcs-cache.service.ts` - Split imports
+7. ✅ `subscriptions.service.ts` - Now imports from subscriptions
+8. ⚠️  `subscriptions.controller.ts` - PARTIALLY fixed
+
+## Issues Found
+
+### subscriptions.controller.ts Problem
+This file imports SIM-related schemas that **don't exist in the domain yet**:
+- `simTopupRequestSchema`
+- `simChangePlanRequestSchema`
+- `simCancelRequestSchema`
+- `simFeaturesRequestSchema`
+
+These schemas exist in the old `packages/domain/src/validation/**` but haven't been moved to the new domain structure yet.
+
+### Missing Schemas/Types Inventory
+
+**In SIM domain (`@customer-portal/domain/sim`):**
+- ✅ HAS: `SimDetails`, `SimUsage`, `SimTopUpHistory` (contracts)
+- ✅ HAS: Provider raw types and request schemas (freebitAccountDetailsRequestSchema, etc.)
+- ❌ MISSING: Business-level request schemas (simTopupRequestSchema, simChangePlanRequestSchema, etc.)
+- ❌ MISSING: Query schemas (subscriptionQuerySchema, invoiceListQuerySchema - these are in old domain/src/validation)
+
+**In Billing domain:**
+- ✅ HAS: `Invoice`, `InvoiceList`, `invoiceSchema`, `invoiceListSchema`
+- ❌ MISSING: `invoiceListQuerySchema` (in old domain/src/validation)
+
+**In Subscriptions domain:**
+- ✅ HAS: `Subscription`, `SubscriptionList`
+- ❌ MISSING: `subscriptionQuerySchema` (in old domain/src/validation)
+
+## Type Error Count
+- **Before batch 1:** 91 errors
+- **After batch 1:** 166 errors (increased because I commented out SIM schema imports)
+
+## Decision Point
+
+**Option A:** Create the missing schemas now in the domains
+- Add query schemas to billing/subscriptions
+- Add business request schemas to sim
+- Time: ~30 minutes
+
+**Option B:** Revert subscriptions.controller.ts changes and continue with other files
+- Fix the easy files first
+- Come back to subscriptions.controller later
+- Time: 5 minutes
+
+**Recommendation:** Option B - revert this one file, continue with remaining 30 files, then create all missing schemas together in Phase 2.
+
+## Next Batch

+# Honest Migration Audit - Current State
+
+**Date:** October 3, 2025  
+**Auditor:** AI Assistant  
+**Purpose:** Reality check before proceeding
+
+---
+
+## 📊 Actual Numbers
+
+### BFF Status
+- **Files importing from bare `@customer-portal/domain`:** 39 files (48 import statements)
+- **Files importing from old packages:** 3 files
+  - `@customer-portal/contracts/*` - 2 files
+  - `@customer-portal/schemas/*` - minimal
+  - `@customer-portal/integrations-freebit/utils` - 1 file
+
+### Portal Status
+- **Files importing any package:** 68 files
+- **Migration status:** NOT STARTED
+
+### Infrastructure Status
+- ✅ Domain structure exists and compiles
+- ✅ Provider namespaces work (`Providers.Whmcs.*`)
+- ❌ Request schemas duplicated (new ones created but old ones still referenced)
+- ❌ Legacy `packages/domain/src/**` still active
+- ❌ Old packages still functional
+
+---
+
+## 🎯 What I Actually Accomplished
+
+### Completed (True)
+1. **Created complete domain structure** - 8 domains with contracts, schemas, providers
+2. **Migrated 12 integration service files** - Updated to use new imports
+3. **Established provider pattern** - Working namespace exports
+4. **Built domain package** - Compiles successfully
+5. **Created request schemas** - New files in `packages/domain/*/providers/*/requests.ts`
+
+### NOT Completed (Reality)
+1. **Did NOT remove old request schema files** - They still exist in `packages/schemas/src/integrations/**`
+2. **Did NOT update all BFF files** - 39 files still use bare `@customer-portal/domain` import
+3. **Did NOT create auth domain** - Auth types still missing
+4. **Did NOT create salesforce domain** - Salesforce types still missing
+5. **Did NOT update Portal** - 68 files need attention
+6. **Did NOT remove legacy packages** - All old code still present
+
+---
+
+## 🔧 Systematic Migration Plan (No Shortcuts)
+
+### Phase 1: Fix BFF Bare Imports (39 files)
+**Estimated time:** 45 minutes
+
+Replace all bare `@customer-portal/domain` imports with specific domain paths:
+
+```typescript
+// ❌ WRONG
+import { Invoice, Subscription } from "@customer-portal/domain";
+
+// ✅ CORRECT
+import { Invoice } from "@customer-portal/domain/billing";
+import { Subscription } from "@customer-portal/domain/subscriptions";
+```
+
+**Files to update:**
+- `apps/bff/src/integrations/whmcs/*.service.ts` (10+ files)
+- `apps/bff/src/modules/auth/**/*.ts` (15+ files)
+- `apps/bff/src/modules/catalog/**/*.ts` (5 files)
+- `apps/bff/src/modules/invoices/**/*.ts` (3 files)
+- `apps/bff/src/modules/orders/**/*.ts` (5 files)
+- And more...
+
+### Phase 2: Create Missing Domains
+**Estimated time:** 1 hour
+
+#### A. Create Auth Domain
+```
+packages/domain/auth/
+  contract.ts     - User, AuthenticatedUser, UserProfile, AuthTokens
+  schema.ts       - All auth request/response schemas
+  index.ts
+```
+
+#### B. Create Salesforce Common Types
+```
+packages/domain/common/
+  salesforce.ts   - SalesforceAccountRecord, SalesforceOrderRecord, etc.
+```
+
+#### C. Add Missing Common Types
+```
+packages/domain/common/
+  types.ts        - Add Address, list types (InvoiceList, etc.)
+```
+
+### Phase 3: Remove Duplicate Request Schemas
+**Estimated time:** 30 minutes
+
+- Delete `packages/schemas/src/integrations/freebit/requests/**`
+- Delete `packages/schemas/src/integrations/whmcs/order.schema.ts` (duplicate)
+- Update any remaining imports to new paths
+
+### Phase 4: Portal Migration (68 files)
+**Estimated time:** 2 hours
+
+Systematically update all Portal files:
+- Components
+- Hooks
+- Services
+- Utilities
+
+### Phase 5: Clean Up Legacy
+**Estimated time:** 1 hour
+
+1. Delete `packages/domain/src/**`
+2. Archive/remove `packages/contracts`
+3. Archive/remove `packages/schemas`
+4. Archive/remove `packages/integrations-*`
+5. Update `tsconfig.json` paths
+6. Update `eslint.config.mjs` rules
+7. Update documentation
+
+---
+
+## ⏱️ Realistic Timeline
+
+| Phase | Time | Cumulative |
+|-------|------|------------|
+| Phase 1: Fix BFF bare imports | 45 min | 45 min |
+| Phase 2: Create missing domains | 1 hour | 1h 45min |
+| Phase 3: Remove duplicates | 30 min | 2h 15min |
+| Phase 4: Portal migration | 2 hours | 4h 15min |
+| Phase 5: Clean up legacy | 1 hour | **5h 15min** |
+
+**Total: ~5-6 hours of focused work**
+
+---
+
+## 🚦 Decision Point
+
+### Option A: Complete Everything Systematically
+**Pros:** Clean result, no tech debt  
+**Cons:** 5-6 hours of work  
+**Recommendation:** Do this if we have the time
+
+### Option B: Incremental Approach
+**Phase 1 only:** Fix bare imports (45 min) → reduces errors significantly  
+**Phase 2 only:** Create missing domains (1 hour) → unlocks remaining types  
+**Then:** Decide on Portal migration timing  
+**Recommendation:** Pragmatic if time-constrained
+
+### Option C: Document and Defer
+Document current state accurately  
+Create tracking issues for each phase  
+Let team prioritize  
+**Recommendation:** If other work is more urgent
+
+---
+
+## 📋 Next Action
+
+**I recommend Option B - Incremental Approach:**
+
+1. **Now:** Fix bare imports in BFF (45 min)
+2. **Next:** Create auth/salesforce domains (1 hour)
+3. **Then:** Verify BFF type-checks cleanly
+4. **Finally:** Plan Portal migration with team
+
+**Would you like me to proceed with Phase 1 (fixing bare imports)?**
+
+---
+
+## 📝 Lessons Learned
+
+1. **Don't claim completion prematurely** - Verify with type-check
+2. **Create duplicates is wasteful** - Should have updated references when creating new schemas
+3. **Audit first, then migrate** - Know the scope before starting
+4. **One domain at a time** - Would have been clearer
+5. **Type-check often** - Catches issues early
+
+This is the honest status. Ready to proceed methodically.

+# Migration Status Update (October 2025)
+
+> The checklist in this document previously claimed a full migration. That was premature. Treat the legacy `@customer-portal/contracts`, `@customer-portal/schemas`, and `@customer-portal/integrations-*` packages as active until the tasks below are completed.
+
+## Current Snapshot
+
+- **Provider exports are live:** Each domain barrel re-exports a `Providers` namespace (`packages/domain/orders/index.ts`, `packages/domain/billing/index.ts`). The subpath mappings in `packages/domain/package.json` enable imports such as `import { Providers } from "@customer-portal/domain/orders"` and `import { transformWhmcsInvoice } from "@customer-portal/domain/billing/providers/whmcs"`.
+- **Apps still lean on legacy packages:** BFF services and controllers continue to import contracts, schemas, and mappers from `@customer-portal/contracts`, `@customer-portal/schemas`, and `@customer-portal/integrations-*`. Examples include `apps/bff/src/modules/orders/services/order-whmcs-mapper.service.ts` and `apps/bff/src/integrations/freebit/services/freebit-operations.service.ts`.
+- **Legacy domain tree still mounted:** Types and schemas under `packages/domain/src/**` are still referenced by the apps. That package cannot be removed yet.
+- **Request schemas are misplaced:** Freebit and WHMCS request schemas remain under `packages/schemas/src/integrations/**` instead of living alongside their providers.
+- **Tooling and docs lag behind:** Lint rules, Dockerfiles, CI scripts, and `tsconfig` path aliases still reference the old packages. Documentation (including this file) had not been updated to reflect the real status.
+- **Missing domain coverage:** Auth flows, Salesforce entities, and common primitives (address, user profile, etc.) have not been migrated into dedicated `packages/domain/*` modules.
+
+## What’s Done
+
+- Domain package exposes the new provider-aware barrels and subpath exports.
+- Provider mapper logic has been lifted into `packages/domain/<domain>/providers/**` for the supported vendors.
+- New import surface has been verified locally (e.g. `Providers.Whmcs`, `Providers.Freebit`).
+
+## Gaps to Close Before Calling the Migration “Complete”
+
+1. **Audit & update imports**
+   - Replace `@customer-portal/contracts/*`, `@customer-portal/schemas/*`, and `@customer-portal/integrations-*` usages across BFF, portal, and integration code with the new domain paths (`@customer-portal/domain/<domain>` and `Providers.<Vendor>`).
+   - Remove fallbacks to `@customer-portal/domain` root barrels in favour of explicit subpaths.
+
+2. **Relocate provider request schemas**
+   - Move Freebit and WHMCS request validators into the relevant provider directories under `packages/domain/<domain>/providers/<provider>`.
+   - Update service call sites (e.g. `freebit-operations.service.ts`) to import from the new locations.
+
+3. **Split out remaining domains**
+   - Introduce an `auth/` domain for authentication types and schemas currently stored in `packages/domain/src/**`.
+   - Add a `salesforce/` (or `common/salesforce.ts`) module for Salesforce entities used by integrations and configuration files.
+   - Consolidate shared primitives in `packages/domain/common/` (address, identifiers, etc.).
+
+4. **Retire the legacy domain package**
+   - Once the apps reference only `packages/domain/<domain>`, delete `packages/domain/src/**` and purge related `tsconfig` and ESLint paths.
+   - Update lint rules (e.g. `eslint.config.mjs`) to forbid importing from the legacy packages.
+
+5. **Deprecate old packages**
+   - After consumers migrate, archive or replace `@customer-portal/contracts`, `@customer-portal/schemas`, and `@customer-portal/integrations-*` with thin re-exports (or remove them entirely if unused).
+   - Ensure Docker builds, CI pipelines, and documentation stop referencing these packages.
+
+6. **Portal alignment & verification**
+   - Apply the same import sweep to the portal (`apps/portal/**`).
+   - Run full type-checks (`pnpm --filter @customer-portal/bff type-check`, etc.) and document remaining issues.
+
+## Suggested Sequence
+
+1. **Codemod imports** across BFF and portal to point at the new domain subpaths and provider namespaces.
+2. **Move request schemas** for Freebit and WHMCS into their provider folders; update services accordingly.
+3. **Add new domain modules** for auth, Salesforce, and shared primitives; backfill exports.
+4. **Remove legacy references** from configs, ESLint, and tooling.
+5. **Retire packages & update docs** once all code points at `@customer-portal/domain/*`.
+
+Track progress by running targeted type-checks and lint rules after each phase, and update this document as milestones are hit.

+# Real Migration Status - Honest Assessment
+
+## Current Reality (Not Marketing)
+
+### ✅ What Actually Works
+1. **Domain Structure Created** - All 8 domains exist with proper exports
+2. **Provider Namespaces** - `Providers.Whmcs.*` and `Providers.Freebit.*` pattern works
+3. **Package Exports** - Subpath mappings in `package.json` are correct
+4. **Domain Compiles** - `packages/domain` builds without errors
+
+### ❌ What's NOT Migrated Yet
+
+**BFF Still Uses Old Packages** - Scanning now to get accurate count...
+
+**Request Schemas NOT Moved** - They're still in `packages/schemas/src/integrations/**`:
+- `packages/schemas/src/integrations/freebit/requests/*.ts` - Still there
+- `packages/schemas/src/integrations/whmcs/*.ts` - Still there
+- I created NEW files in domain but didn't remove/update references to originals
+
+**Missing Domains:**
+- No `auth` domain yet (User, AuthTokens, auth schemas)
+- No `salesforce` domain yet (SalesforceAccountRecord, etc.)
+- No `Address` in common
+
+**Legacy Package Still Active:**
+- `packages/domain/src/**` still exists and is being imported
+- Old packages (`contracts`, `schemas`, `integrations-*`) still functional
+
+## Systematic Migration Plan (Reality-Based)
+
+### Phase 1: Audit Current State
+1. Count ALL imports from old packages in BFF
+2. Count ALL imports from old packages in Portal
+3. List ALL files that need updates
+
+### Phase 2: Execute BFF Migration
+1. Update EVERY file that imports old packages
+2. Remove duplicate request schema files
+3. Create missing domains (auth, salesforce)
+4. Verify with type-check
+
+### Phase 3: Execute Portal Migration
+1. Same systematic approach for Portal
+2. Update ALL component/hook imports
+
+### Phase 4: Clean Up
+1. Delete `packages/domain/src/**`
+2. Archive old packages
+3. Update lint rules
+
+## Next Action: Honest Audit
+
+Running scan to get REAL numbers...
