## 요약

Plane-Origin Authoring Roundtrip Sync `iop-progress` follow-up review completed after 2 loops; final verdict PASS.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G07_0.log` | FAIL | Real Responses semantic SSE events and explicit unsupported fallback classification were incomplete. |
| `plan_cloud_G07_1.log` | `code_review_cloud_G07_1.log` | PASS | Semantic stream delta/completed/error handling, explicit unsupported fallback, regression tests, and docs alignment verified. |

## 구현/정리 내용

- Added Responses streaming progress support with semantic SSE parsing for `response.output_text.delta`, `response.completed`, and `error`.
- Narrowed stream fallback so non-streaming retry happens only for explicit stream unsupported errors, while ordinary validation/model errors return immediately.
- Added regression tests for semantic SSE success, stream unsupported fallback, and no fallback on validation errors.
- Documented `MODEL_RESPONSES_STREAM` progress metadata and fallback behavior in `services/core/README.md`.
