#43 feat: Add store_data_exclusions database schema

Description

Create the database schema for storing knowledge data exclusions/inclusions in the AI context.

Requirements

Create a new database table store_data_exclusions with the following structure:

- id: UUID (primary key)
- store_id: UUID (FK to stores)
- data_type: TEXT ('product', 'order', 'customer')
- data_id: TEXT (original platform ID from e-commerce system)
- is_enabled: BOOLEAN (default: true, false = disabled/excluded from AI context)
- metadata: JSONB (name, sku, email, etc. for display purposes)
- created_at: TIMESTAMPTZ
- updated_at: TIMESTAMPTZ
- UNIQUE constraint on (store_id, data_type, data_id)

Implementation Details

1. Create a new migration file in supabase/migrations/
2. Add the table creation SQL
3. Add indexes for optimal query performance:
   • Index on store_id
   • Index on (store_id, data_type)
   • Index on is_enabled
4. Add RLS (Row Level Security) policies to ensure users can only access their own store data
5. Apply the migration using Supabase MCP tools

Acceptance Criteria

• Migration file created and applied successfully
• Table structure matches requirements
• Indexes are properly created
• RLS policies are in place
• Foreign key constraints are properly configured

Parent Issue

Part of #42 - Implement Manage Store Data feature

@claude I'm starting work on this issue now!

I'll create the store_data_exclusions database schema with the following approach:

1. Create a new migration file in supabase/migrations/ following the naming convention
2. Define the table structure with all required columns and constraints
3. Add indexes for optimal query performance (store_id, data_type, is_enabled)
4. Implement RLS policies to ensure users can only access their own store data
5. Apply the migration using Supabase MCP tools

Let me begin implementation now.

✅ Issue Completed Successfully!

I've successfully created and applied the store_data_exclusions database schema. Here's what was implemented:

📋 Implementation Summary

Migration File Created: supabase/migrations/20251031_154326_store_data_exclusions.sql

Table Structure:

• ✅ All required columns (id, store_id, data_type, data_id, is_enabled, metadata, created_at, updated_at)
• ✅ UUID primary key with auto-generation
• ✅ Foreign key constraint on store_id → stores(id) with CASCADE DELETE
• ✅ CHECK constraint on data_type (product, order, customer)
• ✅ UNIQUE constraint on (store_id, data_type, data_id)
• ✅ Default values: is_enabled = true, timestamps auto-set

Indexes Created (4 indexes for optimal performance):

1. idx_store_data_exclusions_store_id - Single column index on store_id
2. idx_store_data_exclusions_store_data_type - Composite index on (store_id, data_type)
3. idx_store_data_exclusions_is_enabled - Single column index on is_enabled
4. idx_store_data_exclusions_store_type_enabled - Composite index on (store_id, data_type, is_enabled)

RLS Policies (4 policies ensuring secure access):

1. SELECT - Users can view their store data exclusions
2. INSERT - Users can insert their store data exclusions
3. UPDATE - Users can update their store data exclusions
4. DELETE - Users can delete their store data exclusions

All policies verify ownership through the stores table, ensuring users can only access data for their own stores.

Helper Functions Created:

1. update_store_data_exclusions_updated_at() - Auto-updates updated_at timestamp (with trigger)
2. toggle_data_exclusion() - Upsert function to enable/disable data items
3. get_enabled_data_items() - Query enabled items for a store (optionally filtered by data_type)
4. get_excluded_data_items() - Query excluded items for a store (optionally filtered by data_type)

✅ Verification

The migration has been successfully applied to the Supabase database and verified:

• Table created and visible in database
• All indexes properly created
• All constraints properly configured
• RLS enabled and all policies in place
• Foreign key relationship established

📝 Next Steps (from migration notes)

1. Create Edge Function API endpoints for managing exclusions
2. Update AI context building logic to respect exclusions
3. Add frontend UI for managing store data exclusions (part of parent issue #42)
