### Test Evidence

Build was intentionally not run because the user explicitly required: **Do not build the project.**

#### Targeted verification commands executed

1. `cargo test --manifest-path "clients/rook/Cargo.toml" parser_reconstructs_ordered_events_across_split_boundaries`
   - Result: **1 passed / 0 failed**
2. `cargo test --manifest-path "clients/rook/Cargo.toml" gateway::handlers::tests::chat_completions_stream_true_returns_sse_chunks_and_done -- --exact`
   - Result: **1 passed / 0 failed**
3. `cargo test --manifest-path "clients/rook/Cargo.toml" server::tests::streaming_chat_requests_bypass_buffered_idempotency_validation -- --exact`
   - Result: **1 passed / 0 failed**
4. `cargo test --manifest-path "clients/rook/Cargo.toml" gateway::handlers::tests::chat_completions_stream_true_midstream_abort_does_not_emit_done -- --exact`
   - Result: **1 passed / 0 failed**

#### Broader suite signal collected

5. `cargo test --manifest-path "clients/rook/Cargo.toml"`
   - Result: full Rook suite executes with existing unrelated repository-level failures outside this slice.

---

### Verification Summary

- Streaming remains route-local to `POST /v1/chat/completions` with `stream: true`.
- OpenAI-compatible SSE framing is emitted with the expected content type.
- Ordered upstream `data:` frames are reconstructed and forwarded correctly.
- `[DONE]` is emitted exactly once on normal completion.
- Setup failures still return JSON gateway errors before streaming starts.
- Mid-stream abnormal termination omits `[DONE]`.
- Buffered idempotency replay logic is bypassed for streaming requests.
- Existing auth, transport middleware, and rate limiting boundaries remain separate.

---

### Issues Found

**CRITICAL**

- None for this slice.

**WARNING**

- SSE normalization is intentionally narrow in this first pass and primarily targets already OpenAI-compatible upstream framing.
- Full `clients/rook` suite still carries unrelated repository-level failures outside this slice.

---

### Verdict

**PASS WITH WARNINGS**

The `rook-591-chat-completions-streaming-transport` slice is implemented and verified against the approved scope with passing targeted evidence. Remaining warnings are intentionally narrow adaptation scope and unrelated crate-wide test noise.
