---

#### 3. **scripts/SETUP_GUIDE.md**
Comprehensive setup documentation with examples and troubleshooting.

**Sections:**
- Overview of 3-stage setup process
- Prerequisites and quick start
- Detailed script explanations
- Environment variable reference
- Troubleshooting guide
- File structure overview
- Complete checklist

**Usage:**
Reference guide for users running scripts. Explains what each script does and why.

---

### Documentation Created

#### 1. **SUPABASE_QUICKSTART.md** (at project root)
Quick reference guide for developers who want to get up and running fast.

**Features:**
- 5-minute setup guide
- TL;DR section with 3 commands
- Step-by-step instructions
- Copy-paste SQL schema
- Common issues and solutions
- What just happened explanation
- Next steps for full integration

**Target Audience:**
Developers who need to set up quickly without reading extensive documentation.

---

#### 2. **docs/development/supabase-database-setup.md** (Updated)
Complete technical reference with validation against current Supabase docs.

**Updates Made:**
- Environment variable naming (SUPABASE_KEY vs SUPABASE_ANON_KEY)
- RLS policy structure with USING/WITH CHECK examples
- Security best practices (expanded)
- RLS policy details and performance considerations
- Verification steps with SQL queries
- Common implementation issues and fixes
- Testing procedures

**Validations:**
- ✅ Against Supabase Python client documentation
- ✅ Against Supabase RLS best practices (2025)
- ✅ Against real-world implementation patterns
- ✅ Against security guidelines

---

### Database Schema

**Tables:**
1. `analysis_sessions`
   - Stores video analysis results
   - JSONB field for flexible data storage
   - Links to auth.users via user_id
   - Timestamps for audit trail
   - Indexes on user_id and created_at

2. `coach_feedback`
   - Stores coach feedback on analyses
   - Links to analysis_sessions and auth.users
   - Rating system (1-5)
   - Tags array for categorization
   - Timestamps for audit trail
   - Indexes on analysis_session_id and coach_user_id

**Security:**
- Row Level Security (RLS) enabled on both tables
- 5 RLS policies:
  1. users_can_read_own_sessions (SELECT)
  2. users_can_create_own_sessions (INSERT)
  3. coaches_can_read_feedback (SELECT with complex condition)
  4. coaches_can_create_feedback (INSERT)
  5. coaches_can_update_own_feedback (UPDATE)

**Performance:**
- 4 indexes for query optimization
- JSONB for efficient JSON querying
- Cascade delete for referential integrity

### Setup Flow

**Stage 1: Environment Configuration**
```bash
./scripts/setup-supabase-local.sh
# Creates: backend/.env, frontend/.env.local
```

**Stage 2: Database Schema**
```bash
./scripts/setup-supabase-database.sh
# Display OR
python scripts/setup_supabase_db.py
# Generate and save schema

# Then copy SQL into Supabase Dashboard and run
```

**Stage 3: Production Configuration** (Optional)
```bash
./scripts/setup-supabase-production.sh
# Configure Google Cloud secrets
```

### Usage Instructions

#### For Users Following Quick Start:
1. Read: `SUPABASE_QUICKSTART.md`
2. Run: `./scripts/setup-supabase-local.sh`
3. Run: `./scripts/setup-supabase-database.sh`
4. Copy SQL into Supabase
5. Verify and test

#### For Users Needing Full Details:
1. Read: `scripts/SETUP_GUIDE.md`
2. Read: `docs/development/supabase-database-setup.md`
3. Run: `python scripts/setup_supabase_db.py`
4. Review generated SQL in `backend/supabase-schema.sql`
5. Execute and verify

#### For Developers Customizing Setup:
1. Review: `scripts/setup-supabase-database.sh` (bash implementation)
2. Review: `scripts/setup_supabase_db.py` (Python implementation)
3. Modify schema as needed
4. Test in development environment

---

### Key Design Decisions

1. **Two Script Options:**
   - Bash: Minimal dependencies, good for shell environments
   - Python: More features (file save, colored output), good for IDEs

2. **Multiple Setup Paths:**
   - Script displays instructions (flexible)
   - Manual copy/paste (most control)
   - CLI option (if Supabase CLI available)

3. **Validation Before Execution:**
   - Both scripts validate credentials
   - Both scripts check environment configuration
   - Both provide clear error messages

4. **Documentation Triaging:**
   - Quick Start for developers in a hurry
   - Setup Guide for reference during setup
   - Technical Docs for deep understanding
   - Inline script comments for implementation details

5. **Safety Features:**
   - Scripts use `set -e` (exit on error)
   - Validation of environment variables
   - Clear error messages and recovery steps
   - Idempotent SQL (CREATE IF NOT EXISTS)

---

### Validation Status

**Documentation Verified Against:**
- ✅ Official Supabase Python client API (https://supabase.com/docs/reference/python/initializing)
- ✅ Official Supabase RLS guide (https://supabase.com/docs/guides/database/postgres/row-level-security)
- ✅ Real-world Python Supabase implementations (via exa)
- ✅ Current security best practices (2025)

**Key Corrections Implemented:**
- ✅ Environment variable naming conventions
- ✅ RLS policy structure (USING + WITH CHECK)
- ✅ Security warnings about key exposure
- ✅ Verification procedures
- ✅ Testing commands and expected output

- **Well-documented**: Inline comments and output explanations
- **Flexible**: Multiple setup paths supported

If updates needed:
- Bash script: Update `get_schema_sql()` section
