## Correctness (Static — Structural Evidence)

| Requirement                               | Status        | Notes                                                                                                                                                                                                                                                                              |
|-------------------------------------------|---------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Delta seam/end-to-end distinction         | ✅ Implemented | The mapper seam tests are explicitly labeled as seam-only proof in `clients/agent-runtime/src/gateway/mod.rs:2075` and `clients/agent-runtime/src/gateway/mod.rs:2102`, while the denial test is explicitly labeled end-to-end in `clients/agent-runtime/src/gateway/mod.rs:3993`. |
| Canonical HTTP mapping preserved          | ✅ Implemented | `webhook_response_from_dispatch_result(...)` still maps `Completed -> 200` and `Error -> 500` without MCP-specific branching in `clients/agent-runtime/src/gateway/mod.rs:1518`.                                                                                                   |
| Runtime reachability constraint respected | ✅ Implemented | Deny-by-default MCP policy remains unchanged in `clients/agent-runtime/src/agent/dispatcher.rs:66`; no policy bypass or production mapper change was introduced.                                                                                                                   |

## Coherence (Design)

|------------------------------------------------------------------------------------|-----------|------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Split proof between `/webhook` end-to-end denial and seam-level non-denial mapping | ✅ Yes     | Implementation matches `design.md`: denial remains live `/webhook` proof, completed + error are seam proofs in `clients/agent-runtime/src/gateway/mod.rs`. |
| Prefer exactly one non-success seam proof, favoring `Error`                        | ✅ Yes     | Follow-up chose `Error`, matching the preferred branch in `design.md`.                                                                                     |
| Keep production code frozen unless tests expose a defect                           | ✅ Yes     | No production mapping or dispatcher changes were required.                                                                                                 |

## Issues Found

**CRITICAL**

- None.

**WARNING**

- The configured repo-wide verify commands (`make test`, `make build`) passed, but the standard
  Gradle stack did not execute the Rust `agent-runtime` cargo tasks for this change area;
  change-specific confidence therefore depends on the focused `cargo test` run rather than the
  configured verify stack alone.
- The delta scenario for a future runtime-reachable non-denial MCP outcome remains conditional and
  cannot be behaviorally proven until dispatcher policy allows such execution through live
  `/webhook`.

**SUGGESTION**

- Consider aligning `openspec/config.yaml` verify commands with Rust-area changes so standard
  verification includes `clients/agent-runtime` cargo test/build execution.

## Verdict

`PASS WITH WARNINGS`

The follow-up closes the scoped proof gap it set out to close: completed and error MCP-labeled HTTP
mapping are now explicitly proven at the gateway seam, and the reachable MCP denial path remains
proven end to end. Warnings are limited to verification-stack coverage and the intentionally
future-conditional scenario.
