# Service Consolidation Roadmap — 5 Services → 2

> **Goal:** Merge `billing-service`, `growth-service`, and `tracker-service` into `platform-service` so we have one unified Fastify service for all common platform concerns. `extraction-service` stays separate (Python sidecar).
>
> **Created:** 2026-02-14
> **Reviewed:** 2026-02-14 (thorough gap analysis — see Critical Gaps section)
> **Estimated effort:** 4–5 days
> **Blocked by:** Nothing — can start immediately

## Why Consolidate

| Problem | Impact |
|---------|--------|
| 5 separate Node processes for 2 products | Unnecessary operational overhead |
| 5 ports to manage (4001–4005) | Complex docker-compose, run scripts, env files |
| 5 separate Cosmos connections | Wasted connection pool resources |
| 5 CI pipelines | Slow feedback, more config to maintain |
| 5 config schemas with duplicate env vars | Inconsistent config, easy to miss vars |

**After consolidation:** 2 services — `platform-service` (port 4003) + `extraction-service` (port 4005)

---

## 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/*`

## Cosmos Containers (Unified)

All containers served by one Cosmos client in platform-service:

| Origin | Containers |
|--------|-----------|
| **platform** (existing) | `users`, `audit_log`, `feature_flags`, `notification_devices`, `notification_prefs` |
| **billing** → platform | `subscriptions`, `payments`, `plans`, `licenses`, `usage_daily` |
| **growth** → platform | `invitation_codes`, `referrals`, `promo_codes` |
| **tracker** → platform | `tracker_items`, `tracker_comments`, `tracker_votes` |

## Phase 0 — Preparation

> **Goal:** Backup, verify tests pass, baseline everything before any changes.

- [ ] **0.1** Backup all 3 repos via `/repo_backup-main-branch`
- [ ] **0.2** Verify all services build: `pnpm build`
- [ ] **0.3** Verify all tests pass: `pnpm test` (record exact counts per service)
- [ ] **0.4** Baseline test counts: platform ~55, billing ~11, growth ~14, tracker ~45 = **~125 total**
- [ ] **0.5** Run `npx tsc --noEmit` in all 3 dashboards — confirm clean
- [ ] **0.6** Run `python -m pytest tests/ -q` in LysnrAI — confirm Python tests pass

---

## Phase 1 — Merge Growth Service (Smallest First)

> **Goal:** Move invitations, referrals, promos modules into platform-service. Remove growth-service.

### 1.1 Copy modules

- [ ] **1.1.1** Copy `growth-service/src/modules/invitations/` → `platform-service/src/modules/invitations/`

### 1.2 Copy lib files

- [ ] **1.2.1** Copy `growth-service/src/lib/webhooks.ts` → `platform-service/src/lib/webhooks.ts` **(Gap 4)**
- [ ] **1.2.2** Verify growth `product-config.ts` uses same `PRODUCT_ID` export name as platform ✅

### 1.3 Fix imports in copied modules

- [ ] **1.3.1** Update all `../../lib/errors.js` → verify same re-export exists in platform-service
- [ ] **1.3.2** Update all `../../lib/product-config.js` → verify `PRODUCT_ID` export matches
- [ ] **1.3.3** Update all `../../lib/cosmos.js` → verify same pattern
- [ ] **1.3.4** Update `../../lib/webhooks.js` references

### 1.4 Merge config **(Gap 5)**

- [ ] **1.4.1** Add to `platform-service/src/lib/config.ts`:
  - `STRIPE_SECRET_KEY: z.string().optional()` (was required in growth — make optional for now)
  - `WEBHOOK_INVITATION_REDEEMED_URL: z.string().optional()`
  - `WEBHOOK_REFERRAL_STATUS_URL: z.string().optional()`
- [ ] **1.4.2** Add `stripe` (^17.5.0) to `platform-service/package.json` dependencies
- [ ] **1.4.3** Add growth Cosmos containers to platform-service container registry

### 1.5 Register routes

- [ ] **1.5.1** Add imports to `platform-service/src/server.ts`: `invitationRoutes`, `referralRoutes`, `promoRoutes`

- [ ] **1.7.2** `pnpm --filter @lysnrai/platform-service test` — all tests pass (existing + growth ≥ 69)
- [ ] **1.7.3** Remove `services/growth-service/` directory
- [ ] **1.7.4** `pnpm install` — workspace resolution updated (no broken refs)
- [ ] **1.7.5** Commit: `refactor: merge growth-service into platform-service`

---

## Phase 2 — Merge Billing Service

> **Goal:** Move subscriptions, usage, plans, licenses, stripe modules into platform-service. Remove billing-service.

### 2.1 Copy modules

- [ ] **2.1.1** Copy `billing-service/src/modules/subscriptions/` → `platform-service/src/modules/subscriptions/`
- [ ] **2.1.2** Copy `billing-service/src/modules/usage/` → `platform-service/src/modules/usage/`
- [ ] **2.1.3** Copy `billing-service/src/modules/plans/` → `platform-service/src/modules/plans/`
- [ ] **2.1.4** Copy `billing-service/src/modules/licenses/` → `platform-service/src/modules/licenses/`
- [ ] **2.1.5** Copy `billing-service/src/modules/stripe/` → `platform-service/src/modules/stripe/`

### 2.2 Handle billing internal key auth **(Gap 3 — CRITICAL)**

- [ ] **2.2.1** Do NOT copy the global `onRequest` hook from billing-service `server.ts`
- [ ] **2.2.2** Create `platform-service/src/lib/billing-auth.ts` — a Fastify plugin that checks `x-internal-key` header
- [ ] **2.2.3** Register the billing auth plugin ONLY on billing route prefixes:
  ```typescript
  // In server.ts — wrap billing routes with internal key check
  await app.register(async (billingScope) => {
    billingScope.addHook('onRequest', billingKeyGuard);
    await billingScope.register(subscriptionRoutes, { prefix: '/api' });
    await billingScope.register(usageRoutes, { prefix: '/api' });
    await billingScope.register(planRoutes, { prefix: '/api' });
    await billingScope.register(licenseRoutes, { prefix: '/api' });
    // Note: stripeRoutes has its own webhook signature check — skip internal key
  });
  await app.register(stripeRoutes, { prefix: '/api' }); // Outside billing scope
  ```
- [ ] **2.2.4** Verify: auth, audit, tracker, etc. routes are NOT affected by billing key check

### 2.3 Fix imports in copied modules

- [ ] **2.3.1** Update all import paths in copied modules
- [ ] **2.3.2** Verify `PRODUCT_ID` export name matches (billing uses same as platform ✅)

### 2.4 Merge config

- [ ] **2.4.1** Add billing env vars to `platform-service/src/lib/config.ts`:
  - `STRIPE_SECRET_KEY` — upgrade from optional (Phase 1) to required
  - `STRIPE_WEBHOOK_SECRET: z.string().optional()`
  - `STRIPE_PRICE_PRO: z.string().optional()`
  - `STRIPE_PRICE_ENTERPRISE: z.string().optional()`
  - `BILLING_INTERNAL_KEY: z.string().optional()`
  - `BACKEND_URL: z.string().default('http://localhost:8000')`
  - `PLAN_LIMITS_JSON: z.string().optional()`
  - `USAGE_WARN_THRESHOLD: z.coerce.number().default(0.8)`
- [ ] **2.4.2** Add billing Cosmos containers to container registry

### 2.5 Register routes

- [ ] **2.5.1** Add imports to `platform-service/src/server.ts`
- [ ] **2.5.2** Register routes with billing auth scope (see 2.2.3)

### 2.6 Copy + fix tests

- [ ] **2.6.1** Copy all billing test files to platform-service
- [ ] **2.6.2** Fix test import paths

### 2.7 Verify + remove

- [ ] **2.7.1** `pnpm --filter @lysnrai/platform-service build` — clean
- [ ] **2.7.2** `pnpm --filter @lysnrai/platform-service test` — all tests pass (≥ 80)
- [ ] **2.7.3** Remove `services/billing-service/` directory
- [ ] **2.7.4** `pnpm install` — workspace resolution updated
- [ ] **2.7.5** Commit: `refactor: merge billing-service into platform-service`

---

## Phase 3 — Merge Tracker Service

> **Goal:** Move items, comments, votes, public modules into platform-service. Remove tracker-service.

### 3.1 Copy modules

- [ ] **3.1.1** Copy `tracker-service/src/modules/items/` → `platform-service/src/modules/items/`
- [ ] **3.1.2** Copy `tracker-service/src/modules/comments/` → `platform-service/src/modules/comments/`
- [ ] **3.1.3** Copy `tracker-service/src/modules/votes/` → `platform-service/src/modules/votes/`
- [ ] **3.1.4** Copy `tracker-service/src/modules/public/` → `platform-service/src/modules/public/`

### 3.2 Fix Product ID naming **(Gap 1 — CRITICAL)**

- [ ] **3.2.1** In all 4 copied module dirs, replace `DEFAULT_PRODUCT_ID` → `PRODUCT_ID` in imports
- [ ] **3.2.2** Update `../../lib/product-config.js` imports to match platform-service pattern
- [ ] **3.2.3** Add `DEFAULT_PRODUCT_ID` env var support to `platform-service/src/lib/config.ts` for backward compat
- [ ] **3.2.4** In `product-config.ts`, add: `export const DEFAULT_PRODUCT_ID = PRODUCT_ID;` (alias for tracker compat)

### 3.3 Fix auth import

- [ ] **3.3.1** Tracker modules import `extractAuth` from `../../lib/auth.js` — verify platform-service has this file
- [ ] **3.3.2** If missing, create `platform-service/src/lib/auth.ts` re-exporting from `@bytelyst/auth`
- [ ] **3.3.3** Add `@bytelyst/auth` (workspace:*) to platform-service `package.json` **(Gap 2)**
- [ ] **3.3.4** Add `@fastify/rate-limit` (^10.3.0) to platform-service `package.json` **(Gap 2)**
- [ ] **3.3.5** Add `jose` if not already present (tracker uses it for JWT — already in platform ✅)

### 3.4 Merge config

- [ ] **3.4.1** Add `DEFAULT_PRODUCT_ID: z.string().default('lysnrai')` to config schema
- [ ] **3.4.2** Add tracker Cosmos containers to container registry

### 3.5 Register routes

- [ ] **3.5.1** Add imports to `platform-service/src/server.ts`
- [ ] **3.5.2** Register: `itemRoutes`, `commentRoutes`, `voteRoutes`, `publicRoutes`
- [ ] **3.5.3** Public routes must NOT be behind any auth middleware — register at top-level (not inside a scoped plugin)

### 3.6 Copy + fix tests

- [ ] **3.6.1** Copy all tracker test files to platform-service
- [ ] **3.6.2** Fix test import paths
- [ ] **3.6.3** Fix any `DEFAULT_PRODUCT_ID` references in tests
- [ ] **3.6.4** Run tests: 45+ tracker tests must pass

### 3.7 Verify + remove

- [ ] **3.7.1** `pnpm --filter @lysnrai/platform-service build` — clean
- [ ] **3.7.2** `pnpm --filter @lysnrai/platform-service test` — **all 125+ tests pass**
- [ ] **3.7.3** Remove `services/tracker-service/` directory
- [ ] **3.7.4** `pnpm install` — workspace resolution updated
- [ ] **3.7.5** Commit: `refactor: merge tracker-service into platform-service`

---

## Phase 4 — Update Consumers (LysnrAI Repo)

> **Goal:** Update all dashboards, Python clients, scripts, configs, and docker files that reference the old service ports/URLs.

### 4.1 Dashboard API clients **(Gap 6)**

- [ ] **4.2.2** `admin-dashboard-web/src/app/api/stripe/config/route.ts` — `billingServiceUrl` default to port 4003
- [ ] **4.2.3** `admin-dashboard-web/src/lib/stripe-context.tsx` — update all 3 `localhost:4002` references to `localhost:4003`

### 4.3 Ops status route **(Gap 7)**

- [ ] **4.3.1** `admin-dashboard-web/src/app/api/ops/status/route.ts` — remove billing/growth/tracker entries from `SERVICES` array; keep backend + platform + extraction

### 4.7 LysnrAI service stubs **(Gap 11)**

- [ ] **4.7.1** Remove `services/billing-service/` directory (just .env.example stub)
- [ ] **4.7.2** Remove `services/growth-service/` directory
- [ ] **4.7.3** Remove `services/tracker-service/` directory
- [ ] **4.7.4** Update `services/platform-service/.env.example` with merged env vars

### 4.8 Docker Compose (both repos)

- [ ] **4.8.1** `learning_ai_common_plat/docker-compose.yml` — remove billing, growth, tracker service entries

---

## Phase 5 — Documentation & Final Cleanup

> **Goal:** Update all docs, AGENTS.md, and verify nothing is broken.

### 5.1 Documentation

- [ ] **5.1.1** Update `AGENTS.md` in all 3 repos — new service layout (2 services, not 5)
- [ ] **5.1.2** Update `docs/ECOSYSTEM_ARCHITECTURE.md` — consolidated architecture diagram
- [ ] **5.1.3** Update `docs/MIGRATION_GUIDE.md` — single service URL for all API calls
- [ ] **5.1.4** Update `docs/ROADMAP.md` — add consolidation as completed item

### 5.2 Platform-service cleanup

- [ ] **5.2.3** Swagger description reflects all modules
- [ ] **5.2.4** Update platform-service `.env.example` — includes Stripe, webhook, billing key vars

### 5.3 Workspace cleanup

- [ ] **5.3.1** `pnpm install` — no broken workspace refs
- [ ] **5.3.2** Grep entire workspace for `localhost:4001`, `localhost:4002`, `localhost:4004` — must return 0 results
- [ ] **5.3.3** Grep entire workspace for `billing-service`, `growth-service`, `tracker-service` — only docs/history references remain

### 5.4 Final verification

- [ ] **5.4.1** `pnpm build` — all packages + platform-service + extraction-service build
- [ ] **5.4.2** `pnpm test` — all 125+ tests pass in platform-service
- [ ] **5.4.3** `pnpm typecheck` — clean across common-plat workspace
- [ ] **5.4.4** `npx tsc --noEmit` — clean across all 3 LysnrAI dashboards
- [ ] **5.4.5** `python -m pytest tests/ -q` — Python tests still pass (billing client URL changed)
- [ ] **5.4.6** Commit: `docs: update all documentation for consolidated platform-service`

## Summary

| Phase | What | Effort | Tests Moved | Critical Gaps Addressed |
|-------|------|--------|-------------|------------------------|
| **0** | Preparation & backup | 30 min | — | — |
| **1** | Merge growth-service (3 modules) | 2–3 hrs | ~14 | Gap 4 (webhooks), Gap 5 (Stripe key) |
| **2** | Merge billing-service (5 modules) | 4–5 hrs | ~11 | Gap 3 (internal key auth) |
| **3** | Merge tracker-service (4 modules) | 3–4 hrs | ~45 | Gap 1 (product ID), Gap 2 (deps) |
| **4** | Update consumers (17+ files across repos) | 3–4 hrs | — | Gaps 6–11 |
| **5** | Documentation & final verification | 2–3 hrs | — | — |
| **Total** | **5 services → 2** | **~4–5 days** | **~125+ tests** | **12 gaps addressed** |

## Port Allocation (After)

| Service | Port |
|---------|------|
| **platform-service** | **4003** |
| **extraction-service** | **4005** |
| extraction-service python sidecar (internal) | 4006 |

Ports 4001, 4002, 4004 freed up.

## Rollback Strategy

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 | 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 |
