-- Add repetition_id foreign key to cracker parameters tables
-- This migration adds a foreign key to link cracker parameters to their repetitions

-- =============================================
-- 1. ADD REPETITION_ID TO JC CRACKER PARAMETERS
-- =============================================

ALTER TABLE public.jc_cracker_parameters
ADD COLUMN IF NOT EXISTS repetition_id UUID REFERENCES public.experiment_repetitions(id) ON DELETE CASCADE;

-- Add index for performance
CREATE INDEX IF NOT EXISTS idx_jc_cracker_parameters_repetition_id 
    ON public.jc_cracker_parameters(repetition_id);

-- Add unique constraint to ensure one parameter set per repetition
ALTER TABLE public.jc_cracker_parameters
ADD CONSTRAINT unique_jc_cracker_parameters_per_repetition 
    UNIQUE (repetition_id);

-- =============================================
-- 2. ADD REPETITION_ID TO MEYER CRACKER PARAMETERS
-- =============================================

ALTER TABLE public.meyer_cracker_parameters
ADD COLUMN IF NOT EXISTS repetition_id UUID REFERENCES public.experiment_repetitions(id) ON DELETE CASCADE;

-- Add index for performance
CREATE INDEX IF NOT EXISTS idx_meyer_cracker_parameters_repetition_id

-- Add unique constraint to ensure one parameter set per repetition
ALTER TABLE public.meyer_cracker_parameters
