+-- Migration: Store Data Exclusions Schema
+-- Description: Creates table for managing knowledge data exclusions/inclusions in AI context
+-- Date: 2025-10-31
+-- Related Issue: #43
+
+-- ============================================================================
+-- STEP 1: Create store_data_exclusions Table
+-- ============================================================================
+
+-- Table to manage which data items should be included/excluded in AI context
+CREATE TABLE IF NOT EXISTS store_data_exclusions (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  store_id UUID NOT NULL REFERENCES stores(id) ON DELETE CASCADE,
+  data_type TEXT NOT NULL CHECK (data_type IN ('product', 'order', 'customer')),
+  data_id TEXT NOT NULL,
+  is_enabled BOOLEAN NOT NULL DEFAULT true,
+  metadata JSONB,
+  created_at TIMESTAMPTZ DEFAULT NOW(),
+  updated_at TIMESTAMPTZ DEFAULT NOW(),
+  CONSTRAINT unique_store_data_exclusion UNIQUE(store_id, data_type, data_id)
+);
+
+-- ============================================================================
+-- STEP 2: Create Indexes for Optimal Query Performance
+-- ============================================================================
+
+-- Index for querying by store_id
+CREATE INDEX IF NOT EXISTS idx_store_data_exclusions_store_id
+  ON store_data_exclusions(store_id);
+
+-- Composite index for store_id and data_type queries
+CREATE INDEX IF NOT EXISTS idx_store_data_exclusions_store_data_type
+  ON store_data_exclusions(store_id, data_type);
+
+-- Index for filtering by is_enabled status
+CREATE INDEX IF NOT EXISTS idx_store_data_exclusions_is_enabled
+  ON store_data_exclusions(is_enabled);
+
+-- Composite index for frequently used query pattern (store + type + enabled)
+CREATE INDEX IF NOT EXISTS idx_store_data_exclusions_store_type_enabled
+  ON store_data_exclusions(store_id, data_type, is_enabled);
+
+-- ============================================================================
+-- STEP 3: Enable Row Level Security (RLS)
+-- ============================================================================
+
+-- Enable RLS on the table
+ALTER TABLE store_data_exclusions ENABLE ROW LEVEL SECURITY;
+
+-- Policy: Users can view their own store data exclusions
+CREATE POLICY "Users can view their store data exclusions"
+  ON store_data_exclusions FOR SELECT
+  TO authenticated
+  USING (
+    EXISTS (
+      SELECT 1 FROM stores s
+      WHERE s.id = store_data_exclusions.store_id
+      AND s.user_id = auth.uid()
+    )
+  );
+
+-- Policy: Users can insert data exclusions for their own stores
+CREATE POLICY "Users can insert their store data exclusions"
+  ON store_data_exclusions FOR INSERT
+  TO authenticated
+  WITH CHECK (
+    EXISTS (
+      SELECT 1 FROM stores s
+      WHERE s.id = store_data_exclusions.store_id
+      AND s.user_id = auth.uid()
+    )
+  );
+
+-- Policy: Users can update their own store data exclusions
+CREATE POLICY "Users can update their store data exclusions"
+  ON store_data_exclusions FOR UPDATE
+  TO authenticated
+  USING (
+    EXISTS (
+      SELECT 1 FROM stores s
+      WHERE s.id = store_data_exclusions.store_id
+      AND s.user_id = auth.uid()
+    )
+  )
+  WITH CHECK (
+    EXISTS (
+      SELECT 1 FROM stores s
+      WHERE s.id = store_data_exclusions.store_id
+      AND s.user_id = auth.uid()
+    )
+  );
+
+-- Policy: Users can delete their own store data exclusions
+CREATE POLICY "Users can delete their store data exclusions"
+  ON store_data_exclusions FOR DELETE
+  TO authenticated
+  USING (
+    EXISTS (
+      SELECT 1 FROM stores s
+      WHERE s.id = store_data_exclusions.store_id
+      AND s.user_id = auth.uid()
+    )
+  );
+

+END;
+$$ LANGUAGE plpgsql SECURITY DEFINER;
+
+-- Function to get enabled data items for a store
+CREATE OR REPLACE FUNCTION get_enabled_data_items(

+)
+RETURNS TABLE (
+  data_type TEXT,

+BEGIN

+$$ LANGUAGE plpgsql SECURITY DEFINER;

+-- Function to get excluded data items for a store
