### Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|---|---|---|
| Coordinator-Backed Delegation Boundary | ✅ Implemented | `tools/delegate.rs` routes `DelegateExecutionMode::Session` through a single-child `CoordinatorLaunchRequest` and returns the coordinator-owned outcome through the existing `ToolResult` contract. |
| Coordinator State Machine | ✅ Implemented | `clients/agent-runtime/src/agent/coordinator.rs` defines explicit lifecycle states and guarded transitions with terminal immutability. |
| Child Lifecycle Supervision | ✅ Implemented | Stable `ChildAgentId`, `ChildRecord`, registry admission, write-once terminal handling, and ordered inspection live in `coordinator.rs`. |
| Structured In-Process Agent Messaging Envelopes | ✅ Implemented | `EnvelopeMeta`, `MessageEnvelope`, correlation metadata, in-process transport, and fail-closed validation exist in `coordinator.rs`. |
| Deterministic Parallel Fan-Out and Fan-In | ✅ Implemented | `JoinSet` supervision plus launch-index ordering provide deterministic aggregation independent of completion order. |
| Deterministic Failure and Cancel Propagation | ✅ Implemented | Parent-owned cancellation and sibling shutdown behavior are implemented in `Coordinator::run_with_cancellation(...)`. |
| Slice Boundaries and Deferred Track 4 Work | ✅ Implemented | Coordinator comments/tests and delegate behavior keep remote transport, mailbox persistence, worktree isolation, and escalation deferred. |
| Integration and Regression Coverage | ✅ Implemented | Coordinator and delegate regression coverage exists in module-local tests and passed under `cargo test`. |
| Track 4 Roadmap Traceability | ✅ Implemented | `tmp/CLAUDIO_ROADMAP.md` lines 151-178 and the dashboard contract test prove the delivered slice/pending-gap split. |

### Coherence (Design)

| Decision | Followed? | Notes |
|---|---|---|
| Put coordinator foundations under `agent/`, not inside `delegate` | ✅ Yes | `clients/agent-runtime/src/agent/coordinator.rs` is the primary orchestration module and `agent/mod.rs` exports it. |
| Use explicit coordinator and child state machines | ✅ Yes | `CoordinatorState`, `ChildState`, and parent-owned terminal handling are explicit. |
| Define transport-agnostic envelopes with in-process-only transport in Slice 1 | ✅ Yes | `CoordinatorTransport::InProcess` is the only transport variant and invalid transports fail closed. |
| Keep child execution behind a runner abstraction reusing delegated bootstrap | ✅ Yes | `CoordinatorChildRunner` + `DelegatedAgentRunner` reuse delegated bootstrap semantics. |
| Preserve existing `delegate` identity and one-shot behavior | ✅ Yes | `OneShot` remains direct while `Session` routes through the coordinator seam. |
| File changes table expected `agent.rs` modification | ⚠️ Deviated | The implementation reused existing agent bootstrap behavior without a new `agent.rs` diff. This is a valid simplification, not a behavioral miss. |
| Optional rollout gate in `config/schema.rs` | ✅ Not introduced | No new coordinator rollout flag was added; the slice kept the existing config surface and session-mode semantics. |

### Issues Found

**CRITICAL**

- None.

**WARNING**

- The working tree is not clean during re-verification: `clients/web/apps/dashboard/src/composables/chatOnboardingContract.spec.ts` and this `verify-report.md` are modified.
- `make web-test-all` still emits repeated Vue `onScopeDispose()` warnings in `clients/web/apps/dashboard/src/composables/useChat.spec.ts`; they do not fail the command, but they remain validation noise.
- The design file anticipated an `agent.rs` modification, but the implementation correctly reused existing bootstrap behavior instead.

**SUGGESTION**

- Consider eliminating the `useChat.spec.ts` Vue scope warnings so future verify runs stay signal-rich.

### Verdict

**PASS WITH WARNINGS**

All required tasks are complete, all configured verification commands now pass, and all 17 spec scenarios have runtime-backed compliance evidence; remaining issues are non-blocking warnings only.
