+# Migration Guide — Adopting `@bytelyst/*` Packages
+
+Step-by-step guide for integrating `@bytelyst/*` shared packages into a new product or dashboard.
+
+---
+
+## Prerequisites
+
+1. Clone both repos side-by-side:
+
+   ```
+   code/
+   ├── learning_ai_common_plat/   # shared packages + services
+   └── your-product/              # your product repo
+   ```
+
+2. Build all packages:
+   ```bash
+   cd learning_ai_common_plat
+   pnpm install
+   pnpm build
+   ```
+
+---
+
+## Step 1: Add Package Dependencies
+
+In your product's `package.json`, add `file:` references to the packages you need:
+
+```json
+{
+  "dependencies": {
+    "@bytelyst/errors": "file:../learning_ai_common_plat/packages/errors",
+    "@bytelyst/cosmos": "file:../learning_ai_common_plat/packages/cosmos",
+    "@bytelyst/config": "file:../learning_ai_common_plat/packages/config",
+    "@bytelyst/auth": "file:../learning_ai_common_plat/packages/auth",
+    "@bytelyst/api-client": "file:../learning_ai_common_plat/packages/api-client",
+    "@bytelyst/logger": "file:../learning_ai_common_plat/packages/logger"
+  }
+}
+```
+
+Adjust the `../` path depth based on your directory structure. Then run `npm install`.
+
+> **Important:** Run `pnpm build` in `learning_ai_common_plat` before `npm install` in your product. The `file:` refs need compiled `dist/` directories.
+
+---
+
+## Step 2: Wire Up Cosmos DB
+
+Create `src/lib/cosmos.ts`:
+
+```typescript
+import {
+  getCosmosClient,
+  getDatabase,
+  registerContainers,
+  getRegisteredContainer,
+} from '@bytelyst/cosmos';
+
+// Define your containers
+const CONTAINERS = [
+  'users',
+  'settings',
+  'audit_log',
+  // ... your containers
+];
+
+let initialized = false;
+
+export async function initializeAllContainers() {
+  if (initialized) return;
+  await registerContainers(CONTAINERS);
+  initialized = true;
+}
+
+export function getContainer(name: string) {
+  return getRegisteredContainer(name);
+}
+
+export { getCosmosClient, getDatabase, initializeAllContainers };
+```
+
+Required env vars: `COSMOS_ENDPOINT`, `COSMOS_KEY`, `COSMOS_DATABASE`
+
+---
+
+## Step 3: Wire Up Auth (Server-Side)
+
+Create `src/lib/auth-server.ts`:
+
+```typescript
+import { createJwtUtils, hashPassword, verifyPassword } from '@bytelyst/auth';
+
+const jwt = createJwtUtils({
+  issuer: 'your-product-name',
+  accessTokenExpiry: '1h',
+  refreshTokenExpiry: '30d',
+});
+
+export { jwt, hashPassword, verifyPassword };
+```
+
+Required env var: `JWT_SECRET` (min 32 chars)
+
+---
+
+## Step 4: Wire Up Product Identity
+
+Create `src/lib/product-config.ts`:
+
+```typescript
+import { loadProductIdentity } from '@bytelyst/config';
+
+const identity = loadProductIdentity();
+export const PRODUCT_ID = identity.productId;
+export const PRODUCT_NAME = identity.productName;
+```
+
+Required env vars: `DEFAULT_PRODUCT_ID` (or set in `shared/product.json`)
+
+> **Rule:** Every Cosmos document MUST include a `productId` field using this value.
+
+---
+
+## Step 5: Wire Up Service Clients (If Using Microservices)
+
+Create `src/lib/billing-client.ts` (example):
+
+```typescript
+import { createApiClient } from '@bytelyst/api-client';
+
+const billingApi = createApiClient({
+  baseUrl: process.env.BILLING_SERVICE_URL || 'http://localhost:4002',
+  getToken: () => {
+    // Return the current user's JWT token
+    return localStorage.getItem('access_token');
+  },
+});
+
+export async function getSubscription(userId: string) {
+  return billingApi.fetch(`/api/subscriptions/${userId}`);
+}
+```
+
+---
+
+## Step 6: Wire Up Error Handling
+
+Import typed errors for consistent HTTP error responses:
+
+```typescript
+import {
+  BadRequestError,
+  UnauthorizedError,
+  ForbiddenError,
+  NotFoundError,
+  ConflictError,
+} from '@bytelyst/errors';
+
+// In your API routes:
+if (!user) throw new NotFoundError('User not found');
+if (!isAdmin) throw new ForbiddenError('Admin access required');
+```
+
+---
+
+## Step 7: Wire Up Auth Context (React Dashboards)
+
+For admin-style dashboards, use the factory:
+
+```typescript
+import { createAuthProvider } from '@bytelyst/react-auth';
+
+interface MyUser {
+  id: string;
+  email: string;
+  role: string;
+}
+
+const { AuthProvider, useAuth } = createAuthProvider<MyUser>({
+  storagePrefix: 'myapp',
+  onLoginFallback: async (email, password) => {
+    const res = await fetch('/api/auth/login', {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify({ email, password }),
+    });
+    if (!res.ok) return null;
+    const data = await res.json();
+    return { user: data.user, token: data.accessToken };
+  },
+});
+
+export { AuthProvider, useAuth };
+```
+
+> **Note:** If your auth flow needs SSO cookies, registration, or session restore via API calls, keep a custom auth context instead.
+
+---
+
+## Docker Builds
+
+### Fastify Services (in `learning_ai_common_plat`)
+
+Services use pnpm monorepo builds with repo root as context. See any service's `Dockerfile` for the pattern:
+
+- Multi-stage: `pnpm install` → build packages + service → `pnpm deploy`
+- `docker-compose.yml` sets `context: .` with `dockerfile: services/<name>/Dockerfile`
+
+### Next.js Dashboards (in your product repo)
+
+Dashboards need pre-built packages copied into the build context:
+
+1. Run `./scripts/docker-prep-dashboards.sh` to copy `@bytelyst/*` into `.docker-deps/`
+2. Dockerfile copies `.docker-deps/@bytelyst/` to `/learning_ai_common_plat/packages/` so `file:` refs resolve
+
