[alexh-superdev]

Summary

This PR completes the assessment end to end across the frontend and backend. It delivers authenticated publishing, a protected post feed, realtime post notifications, and a cleaner production-ready UI on top of the original starter.

What’s included

• Added JWT-based authentication with register, login, and me
• Added Prisma with SQLite for persistence
• Implemented protected post creation and feed queries
• Added realtime postPublished subscriptions with authenticated graphql-ws support
• Wired the Vue app to Apollo for queries, mutations, and subscriptions
• Added session persistence, route protection, logout, and auth redirects
• Built the publishing workspace with composer, feed, loading/error states, and live updates
• Refined the shell, auth screens, and overall layout for a cleaner UX

Backend

• NestJS GraphQL code-first schema
• Prisma models for users and posts
• JWT auth guard and GraphQL context integration
• Authenticated mutations and queries for registration, login, profile lookup, feed loading, and post creation
• Realtime subscription publishing on successful post creation

Frontend

• Vue 3 + Vue Router app shell
• Apollo client setup for HTTP and WebSocket GraphQL traffic
• Login and registration flows connected to the backend
• Protected posts view with composer and live feed
• Realtime notification handling without page reload
• UX polish for layout, readability, hierarchy, and interaction states

###Verification

• Backend tests passed
• Backend build passed
• Frontend type-check passed
• Frontend production build passed
• Manual smoke flow verified:
  -- register
  -- login
  -- stay signed in on refresh
  -- create a post
  -- receive live updates in another authenticated session

Notes

This implementation keeps the scope intentionally focused on the required assessment flow: authentication, publishing, and realtime updates. Advanced account-management features like password reset, profile editing, and roles are intentionally out of scope.
