### Build & Tests Execution

**Build / static verification**: ✅ Passed

Commands executed in `clients/rook` (scoped to the owning workspace per `openspec/config.yaml`):

- `cargo fmt --all -- --check` → ✅ Passed
- `cargo clippy --all-targets -- -D warnings` → ✅ Passed
- `cargo test` → ✅ Passed

Observed command evidence:
- `cargo clippy --all-targets -- -D warnings` finished successfully in the workspace after the follow-up fixes.
- `cargo test` completed successfully after recompiling `rook v3.6.2`.
- No coverage threshold is configured in `openspec/config.yaml`.

**Coverage**: ➖ Not configured

`openspec/config.yaml` does not define `rules.verify.coverage_threshold`.

### Correctness (Static — Structural Evidence)
| Requirement | Status | Notes |
|------------|--------|-------|
| Shared Effective Rook Configuration Assembly | ✅ Implemented | `load_effective_config(...)` centralizes defaults → file → env → CLI and is used by both `serve` and `rook config export`. Export now accepts a CLI overlay parameter and the parity test asserts equal effective results. |
| `ROOK_*` Environment Override Contract | ✅ Implemented | `parse_env_overlay(...)` deterministically maps documented `ROOK_*` names into typed partial overlays and ignores unsupported variables. README documents supported names and precedence. |
| Redacted Effective Config Export | ✅ Implemented | `RookConfigExportView::from_config(...)` emits non-secret fields and redacts inbound auth token state while preserving operator-visible effective settings such as bind host/port and db path. |
| Invalid Configuration Fails Closed With Operator-Facing Messages | ✅ Implemented | `load_effective_config(...)` validates final resolved config, and both `build_serve_config(...)` and `build_export_config_from_path(...)` rely on that shared validated result. |
| Explicit Precedence Verification and Documentation | ✅ Implemented | README documents defaults < file < env < CLI and automated tests cover precedence behavior for shared config loading. |

---

### Coherence (Design)
| Decision | Followed? | Notes |
|----------|-----------|-------|
| Keep `RookConfig` as the canonical resolved model | ✅ Yes | `RookConfig` remains the resolved config model and converts to `ServerConfig` only at the runtime startup boundary. |
| Represent overlays as partial typed structures | ✅ Yes | File/env/CLI all use partial typed overlays (`PartialRookConfig`, nested partials, `CliRookConfigOverlay`). |
| Centralize assembly in one config loader API | ✅ Yes | `load_effective_config(...)` is the shared assembly entrypoint used by both serve and export. |
| Parse `ROOK_*` into typed partial config | ✅ Yes | `parse_env_overlay(...)` builds typed nested overlays and returns variable-specific parse errors. |
| Redacted export must be a dedicated view model | ✅ Yes | `RookConfigExportView` and nested export views remain the export boundary. |
| CLI flags remain highest-precedence additive overlay | ✅ Yes | Serve uses CLI as final overlay, and export now exercises the same CLI overlay contract in the shared-resolution test path. |
| Remove/narrow bypass paths | ⚠️ Partial | `RookConfig::from_sources_with_path_unvalidated(...)` still exists publicly. It is not used by serve/export, so the core behavior is compliant, but the bypass helper remains available. |
| File changes match design table | ✅ Yes | The key files (`clients/rook/src/config/mod.rs`, `clients/rook/src/main.rs`, `clients/rook/README.md`) were updated consistently with the design. |

### Issues Found

**CRITICAL**
- None.

**WARNING**
- `RookConfig::from_sources_with_path_unvalidated(...)` remains public in `clients/rook/src/config/mod.rs`. This does not break the verified behavior because serve/export do not use it, but it leaves a future bypass path that is broader than the design intent to narrow ad hoc loaders.

**SUGGESTION**
- Consider removing or restricting `from_sources_with_path_unvalidated(...)` if it is no longer needed outside tests or transitional compatibility code.
- Consider removing stale top-of-file `FIXME` comments in `clients/rook/src/config/mod.rs` if they still describe already-implemented work.

### Verdict
PASS

The change now satisfies the checked proposal/spec/design/tasks artifacts for the `gateway` domain slice, and the scoped verification commands (`cargo fmt --all -- --check`, `cargo clippy --all-targets -- -D warnings`, and `cargo test`) all pass in `clients/rook`.
