+## Critical Gaps Found During Review
+
+> These MUST be addressed during the merge or features/tests will break.
+
+### Gap 1: Product ID Naming Inconsistency
+
+Services export product ID differently — modules reference different names:
+
+| Service | Export Name | Source |
+|---------|-----------|--------|
+| **platform-service** | `PRODUCT_ID` | `loadProductIdentity().productId` from `@bytelyst/config` |
+| **growth-service** | `PRODUCT_ID` | same as platform ✅ |
+| **billing-service** | `PRODUCT_ID` | same as platform ✅ |
+| **tracker-service** | `DEFAULT_PRODUCT_ID` | `process.env.DEFAULT_PRODUCT_ID \|\| getProductId()` — **different name** ⚠️ |
+
+**Fix:** When merging tracker modules, change all `DEFAULT_PRODUCT_ID` imports to `PRODUCT_ID` in the copied module files, and add `DEFAULT_PRODUCT_ID` env var support to platform-service's `product-config.ts` for backward compat.
+
+### Gap 2: Missing Dependencies in Platform-Service
+
+Platform-service `package.json` is **missing** these deps needed by merged modules:
+
+| Dep | Needed By | Currently In |
+|-----|-----------|-------------|
+| `stripe` (^17.5.0) | billing modules (stripe webhooks, checkout) | billing-service, growth-service |
+| `@bytelyst/auth` (workspace:*) | tracker modules (`extractAuth`) | tracker-service |
+| `@fastify/rate-limit` (^10.3.0) | tracker rate limiting | tracker-service |
+
+### Gap 3: Billing Internal Key Auth (Global Hook)
+
+`billing-service/src/server.ts` has a **global** `onRequest` hook:
+```typescript
+app.addHook('onRequest', async (req, reply) => {
+  if (path === '/health' || path.includes('/stripe/webhook')) return;
+  const key = req.headers['x-internal-key'];
+  if (key !== INTERNAL_KEY) reply.code(401).send(...)
+});
+```
+This **cannot** be a global hook after merge — it would block auth, audit, tracker, etc. routes.
+
+**Fix:** Convert to a Fastify plugin registered only on billing route prefixes, or add `x-internal-key` check inside each billing route handler.
+
+### Gap 4: Growth Webhooks Library
+
+`growth-service/src/lib/webhooks.ts` dispatches fire-and-forget HTTP callbacks on invitation redeem. References env vars:
+- `WEBHOOK_INVITATION_REDEEMED_URL`
+- `WEBHOOK_REFERRAL_STATUS_URL`
+
+**Fix:** Copy `webhooks.ts` to platform-service `src/lib/`, add both env vars to config schema.
+
+### Gap 5: Growth Config Requires `STRIPE_SECRET_KEY`
+
+Growth-service config requires `STRIPE_SECRET_KEY` as **required** (not optional). Platform-service doesn't currently need Stripe at all.
+
+**Fix:** Add `STRIPE_SECRET_KEY` to platform-service config. Make it **optional** with validation only when billing/growth routes are hit (or make it required after merge since billing always needs it).
+
+### Gap 6: 17+ Consumer Files Need URL Updates (LysnrAI Repo)
+
+**Dashboard API clients (TypeScript):**
+
+| File | Current Env Var | Current Default |
+|------|----------------|-----------------|
+| `admin-dashboard-web/src/lib/billing-client.ts` | `BILLING_SERVICE_URL` | `http://localhost:4002` |
+| `admin-dashboard-web/src/lib/growth-client.ts` | `GROWTH_SERVICE_URL` | `http://localhost:4001` |
+| `user-dashboard-web/src/lib/billing-client.ts` | `BILLING_SERVICE_URL` | `http://localhost:4002` |
+| `user-dashboard-web/src/lib/growth-client.ts` | `GROWTH_SERVICE_URL` | `http://localhost:4001` |
+| `user-dashboard-web/src/app/api/stripe/webhook/route.ts` | `BILLING_SERVICE_URL` | `http://localhost:4002` |
+| `admin-dashboard-web/src/app/api/stripe/config/route.ts` | — | `http://localhost:4002` inline |
+| `admin-dashboard-web/src/lib/stripe-context.tsx` | — | `http://localhost:4002` (3 places) |
+| `tracker-dashboard-web/src/app/api/tracker/[...path]/route.ts` | `TRACKER_API_URL` | `http://localhost:4004` |
+| `tracker-dashboard-web/src/app/api/auth/login/route.ts` | `PLATFORM_API_URL` | `http://localhost:4003` ✅ |
+| `tracker-dashboard-web/src/app/api/auth/me/route.ts` | `PLATFORM_API_URL` | `http://localhost:4003` ✅ |
+
+**Python clients (desktop + backend):**
+
+| File | Current Env Var | Current Default |
+|------|----------------|-----------------|
+| `backend/src/clients/billing_client.py` | `BILLING_SERVICE_URL` | `http://localhost:4002` |
+| `src/cloud/api_sync.py` | `BILLING_SERVICE_URL` | `http://localhost:4002` |
+| `src/cloud/plan_resolver.py` | `BILLING_SERVICE_URL` | `http://localhost:4002` |
+
+All these must change to `PLATFORM_SERVICE_URL` / `http://localhost:4003`.
+
+### Gap 7: Ops Status Health Check Route
+
+`admin-dashboard-web/src/app/api/ops/status/route.ts` checks health of 5 individual services on separate ports. After consolidation, billing/growth/tracker entries must be removed — they'll all respond on platform-service's `/health`.
+
+### Gap 8: Stripe Webhook Test Hardcodes Port
+
+`user-dashboard-web/src/__tests__/stripe-webhook.test.ts` sets:
+```typescript
+process.env.BILLING_SERVICE_URL = 'http://localhost:4002';
+expect(url).toBe('http://localhost:4002/api/stripe/webhook');
+```
+Must update to port 4003.
+
+### Gap 9: Load Test Scripts
+
+- `tests/load/billing-service.js` — `BASE_URL || "http://localhost:4002"`
+- `tests/load/growth-service.js` — `BASE_URL || "http://localhost:4001"`
+
+Must update defaults to port 4003.
+
+### Gap 10: Stripe Documentation
+
+- `docs/STRIPE_SETUP_GUIDE.md` — references `localhost:4002/api/stripe/webhook`
+- `docs/BILLING_GAPS_ANALYSIS.md` — references `localhost:4002/api/stripe/webhook`
+
+### Gap 11: LysnrAI Services Stubs
+
+`learning_voice_ai_agent/services/` contains `.env.example` stubs for each service:
+- `services/billing-service/.env.example`
+- `services/growth-service/.env.example`
+- `services/tracker-service/.env.example`
+- `services/platform-service/.env.example`
+
+After consolidation, remove billing/growth/tracker stubs, keep platform-service with merged env vars.
+
+### Gap 12: Mobile Apps
+
+No references to old service ports found in `mobile_app/` — **no changes needed**. ✅
+Mobile apps call the Python backend (`localhost:8000`), which calls billing-service. The Python backend client (Gap 6) handles the redirection.
+
+### Route Path Collision Check ✅
+
+All services use unique route prefixes — **no collisions**:
+- platform: `/auth/*`, `/audit/*`, `/notifications/*`, `/flags/*`, `/ratelimit/*`, `/blob/*`, `/devices/*`
+- billing: `/subscriptions/*`, `/usage/*`, `/plans/*`, `/licenses/*`, `/payments/*`, `/stripe/*`
+- growth: `/invitations/*`, `/referrals/*`, `/promos/*`
+- tracker: `/items/*`, `/comments/*`, `/votes/*`, `/public/*`

 ## Port Allocation (After)
 
@@ -316,13 +544,17 @@ Each phase has its own commit. If a phase breaks something:
 1. `git revert <commit>` to undo that phase
 2. The old service code is in git history
 3. Backup branches created in Phase 0
+4. Consumers (Phase 4) are updated LAST — services work on old ports until Phase 4
 
 ## Risks & Mitigations
 
 | Risk | Mitigation |
 |------|-----------|
-| Route path collisions between services | All services already use unique prefixes (`/auth/*`, `/subscriptions/*`, `/items/*`, etc.) |
-| Config schema gets large | Group env vars by domain in config.ts with clear comments |
-| Stripe webhook handler needs raw body | Fastify already handles this — just verify after move |
-| Billing internal key auth | Convert from global hook to route-level guard on billing endpoints only |
-| Public tracker routes skip auth | They already handle auth internally — just verify |
+| Route path collisions | Verified ✅ — all services use unique prefixes |
+| Config schema gets large | Group env vars by domain with clear section comments |
+| Stripe webhook raw body | Fastify handles this — verify after move |
+| Billing internal key blocks other routes | Scoped Fastify plugin (Phase 2.2) isolates key check to billing prefixes only |
+| Public tracker routes skip auth | Register outside scoped plugins — verify in Phase 3.5.3 |
+| Python billing client breaks | Change env var name, keep same API paths — transparent to Python code |
+| Stripe webhook test fails | Explicit port update in Phase 4.4 |
+| Product ID mismatch | Alias `DEFAULT_PRODUCT_ID = PRODUCT_ID` in Phase 3.2.4 |
