+
+-- 1. Create 'identities' table in public if it doesn't exist (matches dev schema)
+CREATE TABLE IF NOT EXISTS public.identities (
+    id SERIAL PRIMARY KEY,
+    name VARCHAR(255) NOT NULL UNIQUE,
+    embedding public.vector(768),
+    metadata JSONB DEFAULT '{}'
+);
+
+-- 2. Sync Identities (Audrey Hepburn, Cary Grant)

+SELECT id, name, metadata
+FROM dev.identities
+WHERE name IN ('Audrey Hepburn', 'Cary Grant')
+ON CONFLICT (id) DO NOTHING;
+
+-- 3. Fix Bindings Table in public (ensure identity_id column exists and identity_bindings structure matches)
+-- Check if talent_id exists, rename it to identity_id if so
