-- Fix chain default status to 'pending' instead of 'active'
-- Chains should start as pending until explicitly started

-- Change default for new chains
ALTER TABLE chains ALTER COLUMN status SET DEFAULT 'pending';

-- Update any chains that have no contracts and are 'active' to 'pending'
-- (These were likely created but never properly started)
