### Spec Compliance Matrix
| Requirement | Scenario | Test | Result |
|-------------|----------|------|--------|
| Shared Handled Slash Outcome Adaptation Contract | CLI denied `/resume` stays on the handled-command failure path | `clients/agent-runtime/src/main.rs > tests::cli_resume_target_without_caller_scope_preserves_denied_error_path` | ✅ COMPLIANT |
| Shared Handled Slash Outcome Adaptation Contract | Gateway SSE preserves machine-readable denial for recognized `/resume` | `clients/agent-runtime/src/gateway/mod.rs > gateway::tests::web_chat_stream_preserves_permission_denied_for_resume_target` | ✅ COMPLIANT |
| Shared Handled Slash Outcome Adaptation Contract | Gateway SSE preserves machine-readable invalid-argument failure for a recognized slash command | `clients/agent-runtime/src/gateway/mod.rs > gateway::tests::web_chat_stream_preserves_invalid_arguments_for_tldr_extra_args` | ✅ COMPLIANT |
| Shared Handled Slash Outcome Adaptation Contract | Recognized slash commands still short-circuit on a gateway-facing plan-mode path | `clients/agent-runtime/src/gateway/mod.rs > gateway::tests::web_chat_stream_handles_recognized_slash_commands_in_plan_mode` | ✅ COMPLIANT |
| Transport Parity for Recognized Slash Commands | Focused transport-edge hardening relies on existing slash-command baseline | `clients/agent-runtime/src/main.rs > tests::cli_resume_target_without_caller_scope_preserves_denied_error_path` + `clients/agent-runtime/src/gateway/mod.rs > gateway::tests::web_chat_stream_*` | ✅ COMPLIANT |

**Compliance summary**: 5/5 scenarios compliant

### Correctness (Static — Structural Evidence)
| Requirement | Status | Notes |
|------------|--------|-------|
| Shared Handled Slash Outcome Adaptation Contract | ✅ Implemented | Shared ingress still flows through `pre_execution::evaluate_ingress(...)` and `adapt_handled_ingress(...)`, with CLI adaptation in `clients/agent-runtime/src/main.rs:1530-1569` and gateway adaptation/code mapping in `clients/agent-runtime/src/gateway/mod.rs:1771-1863`. New regression tests exercise the denied, invalid-argument, and plan-mode paths without provider execution. |
| Transport Parity for Recognized Slash Commands | ✅ Implemented | Diff is limited to `clients/agent-runtime/src/main.rs` and `clients/agent-runtime/src/gateway/mod.rs`, adding exactly the four targeted regressions described in the change spec; no new transport matrix or production dispatch branch was introduced. |

---

### Coherence (Design)
| Decision | Followed? | Notes |
|----------|-----------|-------|
| Add transport-edge regressions instead of a full command matrix | ✅ Yes | Only four focused regression tests were added in the existing CLI and gateway test modules. |
| Treat shared ingress and service tests as the behavioral source of truth | ✅ Yes | Production routing remains anchored in `pre_execution::evaluate_ingress(...)` / `adapt_handled_ingress(...)`; the change adds transport-edge assertions only. |
| Freeze current outward error codes rather than redesign envelopes | ✅ Yes | New gateway assertions freeze `permission_denied`, `invalid_arguments`, and existing slash-command handling in plan mode (`unsupported_backend`, not `plan_mode_blocked`). |
| File Changes table alignment | ✅ Yes | Modified files match the design table: `clients/agent-runtime/src/main.rs` and `clients/agent-runtime/src/gateway/mod.rs`; referenced seam/service files were not changed. |

### Issues Found

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

**WARNING** (should fix):
None

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

---

### Verdict
PASS

Implementation matches the change spec, follows the design constraints, and is backed by passing targeted regressions plus a passing full `clients/agent-runtime` test suite.
