-- =============================================================================
-- Phase 7/8 Migration Part 1: Rename stageId -> roundId on 15 tables
-- =============================================================================
-- This migration renames stageId columns to roundId and updates FK constraints
-- to point to the Round table instead of Stage table.
--
-- NOTE: After the pipeline migration (20260213), most tables have BOTH a
-- nullable roundId column (legacy, no FK) AND a stageId column. We must
-- drop the old roundId column before renaming stageId -> roundId.

-- --- 1. EvaluationForm ---

-- Drop old roundId column (nullable, no FK since 20260213 migration)
ALTER TABLE "EvaluationForm" DROP COLUMN IF EXISTS "roundId";

-- Drop FK constraint on stageId
ALTER TABLE "EvaluationForm" DROP CONSTRAINT IF EXISTS "EvaluationForm_stageId_fkey";

-- Drop indexes
DROP INDEX IF EXISTS "EvaluationForm_stageId_version_key";
DROP INDEX IF EXISTS "EvaluationForm_stageId_isActive_idx";

-- Rename column (only if stageId exists)
DO $$ BEGIN
    ALTER TABLE "EvaluationForm" RENAME COLUMN "stageId" TO "roundId";
