Manas AI Project: Handover & Context

This document captures the exact State of the Project as of March 10, 2026 so you can pick up where you left off on another laptop.

Current Status: Frontend-Backend Integration (Debugging)

What is Working ✅

  1. Frontend (Next.js): fully built, multi-lingual (i18n), accessible, and beautiful.
  2. Backend (FastAPI): deployed and live on Render (https://ourmind-931z.onrender.com).
  3. Database (Supabase): schema is set up.
  4. Authentication Flow:
    • Users can successfully "Create Account" using anonymous nicknames (Nickname@manas.app).
    • The frontend auto-redirects the user to the Dashboard after account creation.
    • Supabase "Confirm email" requirement has been successfully disabled.

The Current Blocker ❌

While the frontend connects to the backend perfectly, all API calls (Weather, Garden, Tasks, Chat) are returning 401 Unauthorized errors.

  • The Issue: The FastAPI backend (auth_utils.py) uses PyJWT to validate the Supabase JWT tokens attached in the Authorization: Bearer <token> header.
  • The Error: The tokens are being rejected. Initially, we discovered the Supabase JWT Secret was base64-encoded, which caused an InvalidAlgorithmError.
  • The Latest Attempt: We just pushed a commit (2f740f2) that updates auth_utils.py to attempt decoding with multiple HMAC algorithms (HS256, HS384, HS512). If all fail, it will now explicitly log the token header algorithm to the Render console.

Steps to Resume on Your New Laptop

1. Clone the Repository & Pull Latest Changes Make sure to git pull on the main branch to get the latest backend/utils/auth_utils.py changes.

2. Setup Frontend Environment Create a .env.local file inside the frontend/ directory with these exact contents:

NEXT_PUBLIC_SUPABASE_URL=https://jkshbhhixkleaqbssekv.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJzdXBhYmFzZSIsInJlZiI6Imprc2hiaGhpeGtsZWFxYnNzZWt2Iiwicm9sZSI6ImFub24iLCJpYXQiOjE3NzI5ODg4NDksImV4cCI6MjA4ODU2NDg0OX0.0RG_EaPJWspvMlD__z0Z7FIk8Zdb_4RpcvalDEsgmVc
NEXT_PUBLIC_API_BASE_URL=https://ourmind-931z.onrender.com
NEXT_PUBLIC_DEMO_MODE=false

3. Setup Backend Environment (Optional for Local Testing) If you want to run the backend locally instead of relying on the Render deployment, create a .env file in the backend/ directory with your Groq, HuggingFace, Cartesia, and Supabase credentials.

4. Check Render Logs Go to your Render Dashboard for the ourmind service and check the logs. Play around the app in your new laptop (e.g., send a message in chat) and look at the Render logs. You should see an output like:

[Auth ERROR] All algorithms failed. Token header: alg=XXXX, typ=JWT

Provide that exact alg= value back to me. This will tell us the exact algorithm Supabase is using to sign your tokens, so we can configure PyJWT perfectly in auth_utils.py.

Key Files to Remember

  • frontend/contexts/AuthContext.tsx - Dummy auth domain (@manas.app) logic
  • frontend/lib/apiClient.ts - Axios interceptor attaching the JWT token
  • backend/utils/auth_utils.py - JWT decoding script currently being debugged
  • backend/database/supabase_schema.sql - Underlying DB structure
