-- P2: Person Identity & Talent Management
-- 1. Create Talents table (Global Identities / TMDB Actors)
CREATE TABLE IF NOT EXISTS talents (
    id BIGSERIAL PRIMARY KEY,
    real_name VARCHAR(255) NOT NULL UNIQUE,
    actor_name VARCHAR(255),
    voice_embedding TEXT,
    face_embedding TEXT,
    metadata JSONB DEFAULT '{}',
    created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP
);

-- 2. Create Identity Bindings (Maps machine IDs to Talents)
CREATE TABLE IF NOT EXISTS identity_bindings (
    id BIGSERIAL PRIMARY KEY,
    talent_id BIGINT REFERENCES talents(id) ON DELETE CASCADE,
    binding_type VARCHAR(20) NOT NULL, -- 'face', 'speaker'
    binding_value VARCHAR(100) NOT NULL,
    source VARCHAR(50) DEFAULT 'manual',
    confidence DOUBLE PRECISION DEFAULT 1.0,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
    UNIQUE(talent_id, binding_type, binding_value)
);

CREATE INDEX IF NOT EXISTS idx_identity_bindings_talent ON identity_bindings(talent_id);
CREATE INDEX IF NOT EXISTS idx_identity_bindings_value ON identity_bindings(binding_type, binding_value);

-- 3. Extend person_identities with temporal overlap and confidence fields
ALTER TABLE person_identities ADD COLUMN IF NOT EXISTS character_name VARCHAR(255);
ALTER TABLE person_identities ADD COLUMN IF NOT EXISTS global_person_id BIGINT REFERENCES talents(id);
ALTER TABLE person_identities ADD COLUMN IF NOT EXISTS temporal_overlap_score DOUBLE PRECISION;
ALTER TABLE person_identities ADD COLUMN IF NOT EXISTS audio_visual_confidence DOUBLE PRECISION;
ALTER TABLE person_identities ADD COLUMN IF NOT EXISTS match_strategy VARCHAR(30);
