# Archive Report: mcp-webhook-response-mapping

## Status

- status: archived
- archive_mode: openspec
- verification_verdict: PASS WITH WARNINGS
- archived_at: 2026-03-20

## Executive Summary

Completed change `mcp-webhook-response-mapping` was archived after syncing its accepted
`mcp-runtime` delta into the OpenSpec source of truth. The archive preserves the proof-first
verification outcome and carries forward the remaining warnings about verify-stack coverage and the
future need for end-to-end proof if non-denial MCP `/webhook` execution becomes runtime-reachable.

|-------------|---------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| mcp-runtime | Updated | Replaced `Gateway Webhook MCP Capability Parity` with proof-obligation language that distinguishes runtime-reachable MCP denial from currently blocked non-denial outcomes and requires future end-to-end proof if reachability changes. |

## Archive Operation

- Moved `openspec/changes/mcp-webhook-response-mapping/` to
  `openspec/changes/archive/2026-03-20-mcp-webhook-response-mapping/`.
- Preserved proposal, exploration, design, tasks, delta spec, verification report, and this archive
  report in the audit trail.

## Warnings Carried Forward

1. Standard repo verify flow does not itself exercise the focused Rust cargo tests that provide the
   decisive changed-area proof; archive confidence still depends on the targeted
   `clients/agent-runtime`
   cargo test evidence recorded in `verify-report.md`.
2. If live `/webhook` MCP execution ever becomes runtime-reachable for completed, timeout, or
   failure outcomes, new end-to-end proof will be required beyond the current seam evidence.

## Next Recommended

- Consider wiring `clients/agent-runtime` cargo verification into the standard repo verify path so
  future Rust-area changes do not depend on extra focused test execution.
- If dispatcher policy or runtime flow ever permits non-denial MCP `/webhook` execution, add new
  end-to-end gateway proof for the reachable outcome before treating seam-only evidence as
  sufficient.

## Risks

- Verification remains partly dependent on change-specific Rust test execution outside the default
  repo verify stack.
- Future runtime reachability changes could silently invalidate the current proof split if
  end-to-end
  gateway evidence is not added alongside them.
