-- Reconciliation migration: Add missing foreign keys and indexes
-- The add_15_features migration omitted some FKs and indexes that the schema expects
-- This migration brings the database in line with the Prisma schema

-- Missing Foreign Keys
-- =====================================================

-- RoundTemplate → Program
ALTER TABLE "RoundTemplate" ADD CONSTRAINT "RoundTemplate_programId_fkey"
  FOREIGN KEY ("programId") REFERENCES "Program"("id") ON DELETE CASCADE ON UPDATE CASCADE;

-- RoundTemplate → User (creator)
ALTER TABLE "RoundTemplate" ADD CONSTRAINT "RoundTemplate_createdBy_fkey"
  FOREIGN KEY ("createdBy") REFERENCES "User"("id") ON DELETE RESTRICT ON UPDATE CASCADE;

-- Message → Round
ALTER TABLE "Message" ADD CONSTRAINT "Message_roundId_fkey"
  FOREIGN KEY ("roundId") REFERENCES "Round"("id") ON DELETE SET NULL ON UPDATE CASCADE;

-- EvaluationDiscussion → Round
ALTER TABLE "EvaluationDiscussion" ADD CONSTRAINT "EvaluationDiscussion_roundId_fkey"
  FOREIGN KEY ("roundId") REFERENCES "Round"("id") ON DELETE CASCADE ON UPDATE CASCADE;

-- ProjectFile → ProjectFile (self-relation for file versioning)
ALTER TABLE "ProjectFile" ADD CONSTRAINT "ProjectFile_replacedById_fkey"
  FOREIGN KEY ("replacedById") REFERENCES "ProjectFile"("id") ON DELETE SET NULL ON UPDATE CASCADE;
