+# CodingIT.dev Supabase Database Schema
+
+This directory contains the complete database schema for CodingIT.dev, organized into logical files without duplicates.
+
+## Schema Organization
+
+### Main Schema Files (`/schemas/`)
+
+1. **`extensions.sql`** - PostgreSQL extensions and system setup
+   - Core extensions (uuid-ossp, vector, pg_trgm)
+   - Supabase-specific extensions (pgjwt, supabase_vault)
+   - Foreign data wrapper statistics table
+   - **Load first** before any other schema files
+
+2. **`sequences.sql`** - Database sequences and auto-increment management
+   - All sequences used across schemas
+   - Sequence utility functions and monitoring
+   - **Load second** after extensions
+
+3. **`auth.sql`** - Complete Supabase authentication schema
+   - User management tables (users, sessions, identities)
+   - Multi-factor authentication (MFA) support
+   - SSO and SAML provider configurations
+   - Row Level Security policies for auth tables
+   - **Load third** after sequences
+
+4. **`storage.sql`** - Complete Supabase storage schema
+   - Bucket and object management
+   - Multipart upload support
+   - File organization and metadata
+   - Storage policies and permissions
+   - **Load fourth** after auth
+
+5. **`public.sql`** - Main application schema
+   - All application tables (projects, messages, fragments, etc.)
+   - User profiles and preferences
+   - Teams and organization management
+   - Chat and messaging system
+   - Usage tracking and analytics
+   - Complete business logic functions
+   - Comprehensive RLS policies
+   - **Load last** after all other schemas
+
+### Migration Files (`/migrations/`)
+
+1. **`20250929060300_create_tasks_table.sql`** - Historical tasks table creation
+2. **`20250929163414_create_save_message_function.sql`** - Message handling function
+
+## Loading Order
+
+For a fresh database setup, load files in this order:
+
+```sql
+-- 1. Load extensions first
+\i schemas/extensions.sql
+
+-- 2. Load sequences
+\i schemas/sequences.sql
+
+-- 3. Load auth schema
+\i schemas/auth.sql
+
+-- 4. Load storage schema
+\i schemas/storage.sql
+
+-- 5. Load public schema (includes all business logic)
+\i schemas/public.sql
+
+-- 6. Apply any additional migrations
+\i migrations/20250929060300_create_tasks_table.sql
+\i migrations/20250929163414_create_save_message_function.sql
+```
+
+## Key Features
+
+### Security
+- Row Level Security (RLS) enabled on all user-facing tables
+- Comprehensive security policies
+- Multi-factor authentication support
+- API key management with permissions
+
+### Performance
+- Optimized indexes for all major query patterns
+- Vector indexes for AI embeddings
+- Full-text search capabilities
+- Efficient foreign key relationships
+
+### Scalability
+- Team-based multi-tenancy
+- Usage limits and tracking
+- Analytics and monitoring
+- Horizontal scaling considerations
+
+### Business Logic
+- Complete user management workflow
+- Project and fragment organization
+- Chat message caching and search
+- File upload and storage management
+- Subscription and billing support
+
+## Schema Statistics
+
+- **Total Tables**: 40+ across all schemas
+- **Total Functions**: 15+ business logic functions
+- **Total Indexes**: 50+ performance-optimized indexes
+- **Total Policies**: 25+ RLS security policies
+
+## Maintenance
+
+### Duplicate Removal
+All duplicate schema files have been removed:
+- ✅ Removed: `auth.sql`, `public.sql`, `storage.sql`, `projects.sql`
+- ✅ Consolidated: Functions moved from `complete_database_functions.sql` to `public.sql`
+- ✅ Renamed: `*_complete.sql` files renamed to clean names
+
+### Schema Validation
+All schemas include:
+- Proper constraints and checks
+- Comprehensive indexes
+- Security policies
+- Performance optimizations
+- Documentation and comments
+
+## Development Notes
+
+- Use `IF NOT EXISTS` clauses for safe re-running
+- All tables include proper audit timestamps
+- Foreign key constraints maintain referential integrity
+- Enum types used for better type safety
+- Vector support for AI/ML features included
