Summary

End-to-end smoke test validating the full pipeline with a real Codex CLI: message → ChannelBridge → CodexCliRuntime → codex CLI → NDJSON streaming → AgentDeliveryResult. Gated behind LIVE=1 environment variable. Mirrors the Claude smoke test (#34, PR #35).

Context

The Claude smoke test (PR #35) established the pattern: ChannelBridge → CLI runtime → real subprocess → assertion on result. This test applies the same pattern to Codex, additionally exercising CodexMcpConfigManager's setup/teardown lifecycle (TOML config.toml merge-restore).

CLIs are pre-authenticated on the developer machine — no API key env var checks needed.

Acceptance Criteria

Given the middleware is implemented and ChannelBridge works (PR #33)
When a LIVE=1 smoke test is executed with a pre-authenticated codex CLI
Then a test message is sent through ChannelBridge → CodexCliRuntime
And a coherent text response is received via NDJSON streaming
And the session ID is captured and a follow-up message resumes the session
And the test is skippable in CI (gated behind LIVE=1 environment variable)

Architecture

File

src/middleware/__smoke__/codex.live.test.ts

Pattern

Same as claude.live.test.ts (PR #35):

• describe.skipIf(!LIVE) guard
• beforeAll: create temp dir, SessionMap, ChannelBridge with provider: "codex"
• Test 1: single-turn response (assert payloads, text, sessionId, aborted=false)
• Test 2: session resumption (same channel/user → same sessionId)
• afterAll: cleanup temp dir
• 60s timeout per test

Codex-Specific

• No CLAUDECODE env var unset needed (only Claude has this concern)
• Codex uses CodexMcpConfigManager for TOML config.toml merge-restore — this is exercised implicitly when MCP config is provided
