### Test Evidence

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

#### Broader suite signal collected

12. `cargo test --manifest-path "clients/rook/Cargo.toml"`
    - Result: full Rook suite runs after this slice’s fixes; remaining failures, if any, are outside the rate-limit slice scope.

### Spec Compliance Summary

- Covered surfaces are rate-limited independently: `/api/*`, `/v1/models`, and `/v1/chat/completions`.
- Exhausted surfaces reject with `429 Too Many Requests` and a `Retry-After` header.
- `/api/*` uses admin error shape; `/v1/*` uses gateway error shape.
- Startup/config path now exposes explicit operator-controlled per-surface limit values.
- Dashboard routes remain outside scope.
- Rate-limit middleware composes before auth/handler execution.
- Non-goals remain intact: no per-client/per-IP partitioning, no idempotency, no streaming, no TLS, no RBAC, no outbound provider-auth changes.

---

### Issues Found

**CRITICAL**

- None for this slice.

**WARNING**

- This slice is intentionally global-by-surface and therefore not fairness-oriented; one noisy caller can exhaust a surface-wide budget for all callers.
- The limiter is process-local/in-memory and resets on restart; no cross-process coordination is provided in this slice.

---

### Verdict

**PASS**

The `rook-591-global-surface-rate-limits` slice is implemented and verified against the approved scope with passing targeted evidence and no slice-local critical gaps.
