-- Migration 011: Create talents table
-- Stores global talent profiles (Actors, Real-world identities).

-- Create extension for vector if not exists (usually in 009 or similar)
CREATE EXTENSION IF NOT EXISTS vector;

CREATE TABLE IF NOT EXISTS talents (
    id SERIAL PRIMARY KEY,
    name VARCHAR(255) NOT NULL UNIQUE,
    embedding VECTOR(768), -- Face feature vector
    metadata JSONB DEFAULT '{}',
    created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP
);

-- Ensure identity_bindings references talents if needed
-- Current structure is generic: talent_id (bigint), identity_id (integer - likely person_id?), etc.
-- We will use talent_id to store the ID of the talent, and identity_id to store the ID of the person in person_identities (or we use uuid/identity_value).
-- Let's check current identity_bindings usage.
-- The columns are: talent_id, identity_id, uuid, identity_type, identity_value, binding_type, binding_value.

-- We will use:
-- talent_id: ID from talents table.
-- identity_id: ID of the row in person_identities (if we can map it) OR we rely on identity_value = person_id.
-- identity_type: 'person_id'
-- identity_value: 'Person_0'
-- binding_type: 'named'

-- Add index for faster lookups
CREATE INDEX IF NOT EXISTS idx_identity_bindings_talent_id ON identity_bindings(talent_id);
CREATE INDEX IF NOT EXISTS idx_identity_bindings_identity ON identity_bindings(identity_type, identity_value);
