-- Migration 019: Pipeline-System - Konfigurierbare mehrstufige Analysen
-- Ermöglicht Admin-Verwaltung von Pipeline-Konfigurationen (Issue #28)
-- Created: 2026-03-25

-- ========================================
-- 1. Erweitere ai_prompts für Reset-Feature
-- ========================================
ALTER TABLE ai_prompts
ADD COLUMN IF NOT EXISTS is_system_default BOOLEAN DEFAULT FALSE,
ADD COLUMN IF NOT EXISTS default_template TEXT;

COMMENT ON COLUMN ai_prompts.is_system_default IS 'true = System-Prompt mit Reset-Funktion';
COMMENT ON COLUMN ai_prompts.default_template IS 'Original-Template für Reset-to-Default';

-- Markiere bestehende Pipeline-Prompts als System-Defaults
UPDATE ai_prompts
SET
  is_system_default = true,
  default_template = template
WHERE slug LIKE 'pipeline_%';

-- ========================================
-- 2. Create pipeline_configs table
-- ========================================

  modules JSONB NOT NULL DEFAULT '{}'::jsonb,

  -- Stage 1 prompts (parallel execution)

  -- Example: ARRAY['pipeline_body', 'pipeline_nutrition', 'pipeline_activity']

  -- Stage 2 prompt (synthesis)
  stage2_prompt VARCHAR(100) NOT NULL,
  -- Example: 'pipeline_synthesis'

  -- Stage 3 prompt (optional, e.g., goals)
  stage3_prompt VARCHAR(100),
  -- Example: 'pipeline_goals'

  created TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
  updated TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP

-- ========================================
-- 3. Create indexes
-- ========================================
CREATE INDEX IF NOT EXISTS idx_pipeline_configs_default ON pipeline_configs(is_default) WHERE is_default = true;
CREATE INDEX IF NOT EXISTS idx_pipeline_configs_active ON pipeline_configs(active);

-- ========================================
-- 4. Seed: Standard-Pipeline "Alltags-Check"
-- ========================================
INSERT INTO pipeline_configs (

-- ========================================
-- 5. Seed: Erweiterte Pipelines (optional)
-- ========================================

-- Schlaf-Fokus Pipeline (wenn Schlaf-Prompts existieren)

-- ========================================
-- 6. Trigger für updated timestamp
-- ========================================
DROP TRIGGER IF EXISTS trigger_pipeline_configs_updated ON pipeline_configs;
CREATE TRIGGER trigger_pipeline_configs_updated
  BEFORE UPDATE ON pipeline_configs
  FOR EACH ROW
  EXECUTE FUNCTION update_updated_timestamp();

-- ========================================
-- 7. Constraints & Validation
-- ========================================

-- Only one default config allowed (enforced via partial unique index)
CREATE UNIQUE INDEX IF NOT EXISTS idx_pipeline_configs_single_default
ON pipeline_configs(is_default)
WHERE is_default = true;

-- ========================================
-- 8. Comments (Documentation)
-- ========================================
