-- Migration: Align Agent/MicroDAO model
-- Purpose: Standardize fields for Agent Console, Citizens, MicroDAO Dashboard
-- Date: 2025-11-28

-- ============================================================================
-- AGENTS TABLE
-- ============================================================================

-- Add is_orchestrator flag (agent can create/manage microDAOs)
ALTER TABLE agents
    ADD COLUMN IF NOT EXISTS is_orchestrator boolean NOT NULL DEFAULT false;

-- Create index for orchestrator lookup
CREATE INDEX IF NOT EXISTS idx_agents_is_orchestrator ON agents(is_orchestrator) WHERE is_orchestrator = true;

-- Update existing orchestrators based on kind
UPDATE agents
SET is_orchestrator = true
WHERE kind = 'orchestrator'
  AND is_orchestrator = false;

-- ============================================================================
-- MICRODAOS TABLE
-- ============================================================================

-- Add is_platform flag (microDAO is a platform/district)
ALTER TABLE microdaos
    ADD COLUMN IF NOT EXISTS is_platform boolean NOT NULL DEFAULT false;

-- Add orchestrator_agent_id as alias/copy of owner_agent_id for clarity
-- (keeping owner_agent_id for backward compatibility)
ALTER TABLE microdaos
    ADD COLUMN IF NOT EXISTS orchestrator_agent_id text;

-- Copy owner_agent_id to orchestrator_agent_id where not set
UPDATE microdaos
SET orchestrator_agent_id = owner_agent_id
WHERE orchestrator_agent_id IS NULL
  AND owner_agent_id IS NOT NULL;

-- Add parent_microdao_id for hierarchy (platform -> child microDAOs)
ALTER TABLE microdaos
    ADD COLUMN IF NOT EXISTS parent_microdao_id text;

-- Create indexes
CREATE INDEX IF NOT EXISTS idx_microdaos_is_platform ON microdaos(is_platform) WHERE is_platform = true;
CREATE INDEX IF NOT EXISTS idx_microdaos_orchestrator ON microdaos(orchestrator_agent_id);
CREATE INDEX IF NOT EXISTS idx_microdaos_parent ON microdaos(parent_microdao_id);

-- Add foreign key for parent_microdao_id (self-reference)
-- Note: Using DO block to handle if constraint already exists
