-- sync_to_prod.sql
-- Syncs the latest identity changes from dev schema to public schema (Production/3002)

-- 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)
INSERT INTO public.identities (id, name, metadata)
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
DO $$ 
BEGIN
    IF EXISTS (SELECT 1 FROM information_schema.columns WHERE table_schema = 'public' AND table_name = 'identity_bindings' AND column_name = 'talent_id') THEN
        ALTER TABLE public.identity_bindings RENAME COLUMN talent_id TO identity_id;
    END IF;
END $$;

-- 4. Sync Bindings (Mapping dev columns to public schema)
-- public schema uses: identity_id, uuid, binding_type, binding_value
INSERT INTO public.identity_bindings (identity_id, uuid, binding_type, binding_value)
SELECT identity_id, '384b0ff44aaaa1f1', identity_type, identity_value
FROM dev.identity_bindings
WHERE identity_value IN ('Person_17', 'Person_4')
ON CONFLICT DO NOTHING;

-- 5. Sync Merge History
INSERT INTO public.merge_history (merge_id, target_person_id, source_person_ids, original_target_stats, original_source_stats, merged_at)
SELECT merge_id, target_person_id, source_person_ids, original_target_stats, original_source_stats, merged_at
FROM dev.merge_history
WHERE target_person_id IN ('Person_17', 'Person_4')
ON CONFLICT DO NOTHING;

-- 6. Perform Data Merges in Public (Simulating the actions taken in Dev)

-- A. Merge Person_25 -> Person_17 (Audrey Hepburn)
-- Update Appearances
UPDATE public.person_appearances
SET person_id = 'Person_17'
WHERE person_id = 'Person_25' AND video_uuid = '384b0ff44aaaa1f1';

-- Update Name and Count
UPDATE public.person_identities
SET name = 'Audrey Hepburn',
    appearance_count = (SELECT count(*) FROM public.person_appearances WHERE person_id = 'Person_17' AND video_uuid = '384b0ff44aaaa1f1')
WHERE person_id = 'Person_17' AND video_uuid = '384b0ff44aaaa1f1';

-- Delete Source
DELETE FROM public.person_identities
WHERE person_id = 'Person_25' AND video_uuid = '384b0ff44aaaa1f1';

-- B. Merge Person_46, Person_70, Person_3 -> Person_4 (Cary Grant)
-- Update Appearances
UPDATE public.person_appearances
SET person_id = 'Person_4'
WHERE person_id IN ('Person_46', 'Person_70', 'Person_3') AND video_uuid = '384b0ff44aaaa1f1';

-- Update Name and Count
UPDATE public.person_identities
SET name = 'Cary Grant',
    appearance_count = (SELECT count(*) FROM public.person_appearances WHERE person_id = 'Person_4' AND video_uuid = '384b0ff44aaaa1f1')
WHERE person_id = 'Person_4' AND video_uuid = '384b0ff44aaaa1f1';

-- Delete Sources
DELETE FROM public.person_identities
WHERE person_id IN ('Person_46', 'Person_70', 'Person_3') AND video_uuid = '384b0ff44aaaa1f1';
