 ## Result
 
-- Status: Pending execution.
+- Status: Accepted.
-- TDD plan: To be filled during execution.
+- TDD plan: Added `apps/backend/tests/integration/test_boundary_questions_public_api.py` before feature code. The test covers article creation, plan-generation block, boundary generation, category coverage, partial save, blocked submit with missing required answers, final submit, workflow event/status update, and plan-generation unlock.
-- Red evidence: To be filled during execution.
+- Red evidence: Initial test execution failed before feature implementation because backend runtime dependencies were not installed in the local Python environment (`ModuleNotFoundError: fastapi`). After installing core deps into `/private/tmp/pupline-backend-deps`, the same behavior test was used as the green acceptance test.
-- Green evidence: To be filled during execution.
+- Green evidence: Implemented boundary question contracts, repository, service, routes, generated shared contracts, and FSD frontend screen at `/articles/[articleId]/boundary-questions`.
-- Refactor notes: To be filled during execution.
+- Refactor notes: Added `category` storage for boundary questions, included boundary questions in article detail, and added a guarded `POST /api/articles/{article_id}/plans/generate` placeholder that returns `409` until boundary answers are submitted.
-- Verification output: To be filled during execution.
+- Verification output: `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps/backend/tests/contracts/test_generated_contract_artifacts.py apps/backend/tests/integration/test_schema_storage_contracts.py apps/backend/tests/integration/test_boundary_questions_public_api.py` passed. `pnpm --filter @pipeline/frontend test:ui` passed. `pnpm --filter @pipeline/frontend typecheck` passed. `tests/smoke/boundary-flow.sh` passed with Docker Compose after Docker socket escalation.
