+-- Migration: Refactor configs to link via tasks.config_id
+-- This migration adds config_id to tasks table and migrates existing configs to tasks
+-- After migration: configs only contain words_count, max_cards (name and try_message removed)
+
+-- ============================================
+-- Step 1: Add config_id to tasks
+-- ============================================
+ALTER TABLE tasks 
+ADD COLUMN IF NOT EXISTS config_id INTEGER REFERENCES configs(id) ON DELETE SET NULL;
+
+CREATE INDEX IF NOT EXISTS idx_tasks_config_id ON tasks(config_id);
+
+-- Unique index: only one task per config
+CREATE UNIQUE INDEX IF NOT EXISTS idx_tasks_config_id_unique 
+ON tasks(config_id) WHERE config_id IS NOT NULL AND deleted = FALSE;
+
+COMMENT ON COLUMN tasks.config_id IS 'Link to test config. NULL if task is not a test.';
+
+-- ============================================
+-- Step 2: Migrate existing configs to tasks
+-- Create a task for each config that doesn't have one yet
+-- ============================================
+INSERT INTO tasks (user_id, name, reward_message, repetition_period, repetition_date, config_id)
+SELECT 
+    c.user_id,
+    c.name,                    -- Config name -> Task name
+    c.try_message,             -- try_message -> reward_message
+    '0 day'::INTERVAL,         -- repetition_period = 0 (infinite task)
+    '0 week',                  -- repetition_date = 0 (infinite task)
+    c.id                       -- Link to config
+FROM configs c
+WHERE c.name IS NOT NULL       -- Only configs with names
+AND NOT EXISTS (
+    SELECT 1 FROM tasks t WHERE t.config_id = c.id AND t.deleted = FALSE
+);
+
+-- ============================================
+-- Step 3: Remove name and try_message from configs
+-- These are now stored in the linked task
+-- ============================================
+ALTER TABLE configs DROP COLUMN IF EXISTS name;
