### Spec Compliance Matrix
| Requirement | Scenario | Test | Result |
|-------------|----------|------|--------|
| Centralized Dispatch Through the Pre-Execution Seam | In-scope session commands use the shared seam across supported ingress surfaces | `src/pre_execution/mod.rs > ingress_classifies_in_scope_session_commands_through_shared_seam`; `src/main.rs > cli_shared_ingress_handles_compact_before_agent_execution`; `src/gateway/mod.rs > maybe_handle_http_ingress_intercepts_compact_through_shared_ingress`; `src/gateway/webhook_dispatch.rs > execute_intercepts_suspend_through_shared_ingress_before_provider_execution`; `src/channels/mod.rs > ingress_outcome_handles_tldr_through_shared_ingress_before_memory_enrichment` | ✅ COMPLIANT |
| Centralized Dispatch Through the Pre-Execution Seam | Unknown or non-command input still falls through normally | `src/pre_execution/mod.rs > ingress_preserves_unknown_slash_like_input`; `src/main.rs > cli_unknown_slash_like_input_falls_through`; `src/gateway/mod.rs > maybe_handle_http_ingress_ignores_unknown_slash_like_input`; `src/gateway/webhook_dispatch.rs > execute_preserves_unknown_slash_like_input_for_normal_provider_flow`; `src/channels/mod.rs > ingress_outcome_preserves_unknown_slash_like_input` | ✅ COMPLIANT |
| Existing Slash Session Behavior Preservation | Resume authorization rules remain intact after registry-backed dispatch | `src/session_commands/registry.rs > dispatch_preserves_resume_authorization_after_registry_lookup`; `src/gateway/mod.rs > maybe_handle_http_ingress_preserves_permission_denied_for_resume_target`; `src/gateway/webhook_dispatch.rs > execute_preserves_permission_denied_for_resume_target`; `src/channels/mod.rs > ingress_outcome_preserves_permission_denied_for_resume_target` | ✅ COMPLIANT |
| Existing Slash Session Behavior Preservation | Slash-session backend checks remain intact after registry-backed dispatch | `src/pre_execution/mod.rs > ingress_classifies_in_scope_session_commands_through_shared_seam`; `src/main.rs > cli_shared_ingress_handles_compact_before_agent_execution`; `src/gateway/webhook_dispatch.rs > execute_intercepts_suspend_through_shared_ingress_before_provider_execution`; `src/channels/mod.rs > ingress_outcome_handles_tldr_through_shared_ingress_before_memory_enrichment` | ✅ COMPLIANT |
| Registry Bindings Are the Sole Production Session-Command Dispatch Entry | Registry binding remains the only production dispatch entry for in-scope session commands | `src/session_commands/registry.rs > dispatch_routes_suspend_via_registry`; `src/session_commands/registry.rs > dispatch_preserves_resume_authorization_after_registry_lookup`; `src/pre_execution/mod.rs > ingress_classifies_in_scope_session_commands_through_shared_seam` | ✅ COMPLIANT |
| Registry Bindings Are the Sole Production Session-Command Dispatch Entry | Transport-specific wrappers stay outside the production dispatch decision | `src/gateway/mod.rs > maybe_handle_http_ingress_preserves_resume_success_for_authorized_scope`; `src/gateway/webhook_dispatch.rs > execute_intercepts_authorized_resume_success_before_provider_execution`; `src/channels/mod.rs > ingress_outcome_preserves_resume_success_for_authorized_scope`; `src/main.rs > cli_session_command_success_returns_message` | ✅ COMPLIANT |

**Compliance summary**: 6/6 scenarios compliant

### Correctness (Static — Structural Evidence)
| Requirement | Status | Notes |
|------------|--------|-------|
| Centralized Dispatch Through the Pre-Execution Seam | ✅ Implemented | `clients/agent-runtime/src/pre_execution/mod.rs` keeps `default_registry().dispatch(...)` inside `evaluate_ingress(...)`, and CLI/gateway/webhook/channels all route through that seam before transport-specific wrapping. |
| Existing Slash Session Behavior Preservation | ✅ Implemented | Service-layer outcomes remain unchanged; surface tests still observe authorization-denied and unsupported-backend behavior instead of bypassing service checks. |
| Registry Bindings Are the Sole Production Session-Command Dispatch Entry | ✅ Implemented | `SlashCommandRegistry::recognizes(...)` was removed from `clients/agent-runtime/src/session_commands/registry.rs`; no remaining production `recognizes(` call sites were found under `clients/agent-runtime/src`. |

---

### Coherence (Design)
| Decision | Followed? | Notes |
|----------|-----------|-------|
| Keep the shared ingress seam as the only production dispatch entry | ✅ Yes | All touched transports call `evaluate_ingress(...)` and adapt via handled-ingress classification. |
| Delete dead recognition helpers instead of preserving compatibility noise | ✅ Yes | `recognizes(...)` is removed and helper/comment names now describe shared handled-ingress routing. |
| Prove routing at the seam, not with a full transport-by-command matrix explosion | ✅ Yes | Verification found one seam-level multi-command test plus focused per-surface interception and authz regressions, matching the narrow proof strategy in `design.md`. |
