## Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|---|---|---|
| `SupervisedOrchestrationService` with `launch()`, `inspect()`, `cancel()`, `run_to_completion()` | ✅ Implemented | `agent/coordinator.rs` |
| `OrchestrationHandle`, `OrchestrationLaunchReceipt`, `OrchestrationSnapshot`, `ChildLifecycleView`, `OrchestrationOutcomeView`, `CancelDisposition`, `CancelResult` public types | ✅ Implemented | All defined in `coordinator.rs` |
| `DelegateLaunchTool` implements `Tool` trait | ✅ Implemented | `tools/delegate_launch.rs` |
| `DelegateInspectTool` implements `Tool` trait | ✅ Implemented | `tools/delegate_inspect.rs` |
| `DelegateCancelTool` implements `Tool` trait | ✅ Implemented | `tools/delegate_cancel.rs` |
| All three tools registered in `tools/mod.rs` via `add_delegate_tool()` sharing one `Arc<SupervisedOrchestrationService>` | ✅ Implemented | `tools/mod.rs` |
| `delegate.rs` backward-compatible single-child path via `run_to_completion()` | ✅ Implemented | `tools/delegate.rs` |
| `coordinator` module exported from `agent/mod.rs` as `pub mod coordinator` | ✅ Implemented | `agent/mod.rs` |
| New tools present in bootstrap allowed-tool list | ✅ Implemented | `bootstrap/mod.rs` lines 49–51 |

## Coherence (Design)

| Decision | Followed? | Notes |
|---|---|---|
| Use `RwLock<HashMap<OrchestrationHandle, RunEntry>>` as the state store | ✅ Yes | Verified in `coordinator.rs` |
| `RunEntry` is enum with `Active` and `Terminal` variants | ✅ Yes | Matches design |
| Three separate tool files (`delegate_launch`, `delegate_inspect`, `delegate_cancel`) | ✅ Yes | Each in its own file |
| Tools share one `Arc<SupervisedOrchestrationService>` instance | ✅ Yes | Registered in `add_delegate_tool()` |
| `delegate.rs` schema unchanged (`{agent, prompt, context}`, `additionalProperties: false`) | ✅ Yes | Backward compat preserved |
| Rejected alternatives (e.g., actor model, per-call state) not implemented | ✅ Yes | No evidence of alternatives |

## Issues Found

**CRITICAL** (must fix before archive): None

**WARNING** (should fix): None

**SUGGESTION** (nice to have): None

---

## Verdict

### ✅ PASS

All 15 tasks complete. Clippy clean under `-D warnings`. All tests pass (0 failures). 38/38 spec scenarios have passing tests as behavioral evidence. Bootstrap correctly classifies the three new tools. Backward compatibility of the single-child `delegate` tool is preserved and tested. Implementation is fully coherent with the design decisions documented in `design.md`.

**Ready for `sdd-archive`.**
