• ✅ No Hardcoded Secrets: All API keys loaded from environment variables
• ✅ Project Visibility: Private/Team-wide controls with database enforcement

• ✅ No XSS Vulnerabilities: No use of innerHTML or dangerouslySetInnerHTML
• ✅ No Code Injection: No eval() or new Function() usage
• ✅ Input Validation: Email, password, and form validation on client and server
• ✅ Error Messages: Generic errors that don't expose sensitive information
• ✅ React: Automatic XSS protection through JSX escaping

• ✅ HTTPS Only: Vercel enforces HTTPS on all connections
• ✅ CORS: Properly configured by Supabase backend
• ✅ Rate Limiting: Handled by Supabase backend
• ✅ API Key Protection: Gemini and Google Drive API keys in environment variables

• ✅ .gitignore: All .env files and secrets excluded from git
• ✅ Build Process: Vite build strips development code
• ✅ Dependencies: Regular updates via npm audit

Status: DEVELOPMENT ONLY - NOT SECURE

This file provides a localStorage-based implementation for development:

• Passwords stored as base64 (easily reversible) - NOT SECURE
• No server-side validation
• Single-device only
• No encryption

Solution: Set VITE_USE_SUPABASE=true in production (already configured)

View Policy: Users can view projects if:

1. They are a member of the project's team, AND
2. Either:
   • Project visibility = 'team' (all team members can see)
   • Project visibility = 'private' AND (user is owner OR user is in collaborators)

Update Policy: Users can update if:

• User is the project owner, OR
• User is in the project's collaborators array

Delete Policy: Users can delete if:

• User is the project owner, OR
• User is team admin/owner AND project visibility = 'team'

Insert Policy: Users can create projects if:

• They are a member of the target team
• They set themselves as the owner

• Environment variables set in Vercel
• VITE_USE_SUPABASE=true
• RLS enabled on all Supabase tables
• Anon key used (not service role key)
• HTTPS enforced
• No console.log with sensitive data

• No hardcoded secrets
• Input validation on forms
• Generic error messages
• No XSS vulnerabilities
• No SQL injection (parameterized queries via Supabase)

• RLS policies on all tables
• team_members table enforces team access
• projects table enforces project-level permissions
• profiles table protected by RLS
• Database triggers ensure data integrity
