+
+## Key Findings Summary
+
+### Central Service
+- **Name:** mana-core-auth
+- **Port:** 3001
+- **Framework:** NestJS + Better Auth
+- **Algorithm:** EdDSA JWT
+- **Database:** PostgreSQL with Drizzle
+
+### Integration Patterns
+- **Path A:** `@manacore/shared-nestjs-auth` (lightweight)
+- **Path B:** `@mana-core/nestjs-integration` (with credits)
+- **Pattern:** Centralized validation via `/api/v1/auth/validate`
+
+### Canonical Design
+- **JWT Claims:** Minimal (sub, email, role, sid only)
+- **Token Expiry:** 15 minutes (access), 7 days (refresh)
+- **Rotation:** Refresh token rotation + soft delete
+- **Guards:** Use `@UseGuards()` decorator
+- **Injection:** Use `@CurrentUser()` decorator
+
+### Environment Setup
+```env
+# Required
+MANA_CORE_AUTH_URL=http://localhost:3001
+
+# Development (optional)
+NODE_ENV=development
+DEV_BYPASS_AUTH=true
+DEV_USER_ID=test-uuid
+
+# Better Auth manages JWT (DO NOT SET)
+# JWT_PRIVATE_KEY=...
+# JWT_PUBLIC_KEY=...
+```
+
+---
+
+## Architecture Decisions (Validated)
+
+1. **Minimal JWT Claims**
+   - Why: Prevents stale data (credits, org info change frequently)
+   - Impact: Smaller tokens, better performance
+   - Evidence: All backends follow pattern
+
+2. **EdDSA Algorithm**
+   - Why: Better performance + security than RSA
+   - Impact: Smaller keys (32 bytes vs 2048+ bits)
+   - Source: Better Auth framework default
+
+3. **Centralized Validation**
+   - Why: Single source of truth, reduces key distribution
+   - Impact: All backends call `/api/v1/auth/validate`
+   - Benefit: Easier security updates
+
+4. **Refresh Token Rotation**
+   - Why: Prevent token replay attacks
+   - Impact: Old token revoked on refresh
+   - Result: Enhanced session security
+
+---
+
+## Common Mistakes (Avoid!)
+
+1. **Wrong JWT Algorithm**
+   - WRONG: RS256 or HS256
+   - RIGHT: EdDSA (Better Auth default)
+
+2. **Hardcoded Claims**
+   - WRONG: Adding org data, credits to JWT
+   - RIGHT: Fetch via API endpoints
+
+3. **Missing Guard**
+   - WRONG: Manual token parsing in controllers
+   - RIGHT: Use `@UseGuards()` decorator
+
+4. **Wrong Library**
+   - WRONG: `import jwt from 'jsonwebtoken'`
+   - RIGHT: Use `jose` library for verification
+
+5. **Environment Variable**
+   - WRONG: Setting JWT_PRIVATE_KEY
+   - RIGHT: Let Better Auth manage keys
+
+See **AUTH_ARCHITECTURE_REPORT.md** Section 10 for troubleshooting guide.

+## Testing Quick Commands
+
+### Get Token
+```bash
+curl -X POST http://localhost:3001/api/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email": "test@example.com", "password": "password123"}'
+```
+
+### Test Protected Endpoint
+```bash
+curl http://localhost:3007/api/favorites \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+### Validate Token
+```bash
+curl -X POST http://localhost:3001/api/v1/auth/validate \
+  -H "Content-Type: application/json" \
+  -d "{\"token\": \"$TOKEN\"}"
+```
+
+### Decode Token
+```bash
+echo $TOKEN | cut -d'.' -f2 | base64 -d | jq '.'
+```
