Summary

Fix Codex MCP app interactions failing when the Codex app-server restarts or unloads a native thread.

When an MCP operation encounters a thread not found error, the adapter now resumes the native thread and retries the original request.

Changes

Add recovery for unloaded Codex native threads.
Resume the native thread using thread/resume with excludeTurns: true.
Retry failed MCP operations after successfully resuming the thread.
Apply recovery to:
- MCP tool listing (listTools)
- MCP tool execution (callTool)
- MCP resource reading (readResource)
Add a regression test covering resource reads after a native thread is unloaded.

Walkthrough

Codex MCP tool listing, tool calls, and resource reads now resume an unloaded thread after a matching thread not found: error, then retry the operation. A replay-based test verifies recovery for a resource read.

Changes: Codex MCP thread recovery

Layer / File(s)	Summary
Resume and retry MCP operations `apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts`, `apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts`	A shared wrapper resumes the thread with `excludeTurns: true` after a matching missing-thread error, then retries `listTools`, `callTool`, or `readResource`. The replay test verifies that a resource read returns its result after recovery.

Estimated code review effort: 2 (Simple) | ~15 minutes

Explanation

The description explains the problem, implementation, affected MCP operations, linked issue, and validation results. It does not include a dedicated Scope and approval section or explicit approval evidence, but the focused bug fix and issue link provide sufficient context.

Full details: Linked Issues check

Explanation

Issue #29433 requires MCP access after a retained Codex thread unloads. CodexAdapterV2.ts detects Codex -32600 errors beginning with thread not found:, resumes the same native thread with excludeTurns: true, and retries the request. The recovery covers listTools, callTool, and readResource. The regression test verifies resume, retry, and the successful resource result without a model turn.

Handle the known request-error tag with Effect.catchTags.
This branch uses Effect.catchIf with Schema.is(CodexAppServerRequestError). Keep the code-and-message check inside a CodexAppServerRequestError handler, and fail with the original error when it does not match. As per coding guidelines, “Catch known tags with Effect.catchTags({ ... }), even for one tag, not catchTag or catchIf with a schema predicate.” (raw.githubusercontent.com)

Use current thread settings when recovery resumes Codex.

The recovery wrapper closes over the modelSelection and runtimePolicy supplied to openSession. Later turns can use different settings, but recovery still sends the captured model and cwd to thread/resume. Pass the current thread settings into recovery so an MCP operation does not run with stale Codex settings.

External image Unverified finding Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Remove the duplicate isCodexAppServerRequestError declaration.
The file already declares const isCodexAppServerRequestError = Schema.is(CodexErrors.CodexAppServerRequestError); at module scope, at Line 348. This line declares the same name again inside the openSession closure. The inner declaration shadows the outer one. Delete this line and use the module-level predicate.

Provide the Digest layer for the replay test.

makeCodexReplayHarness requires Digest.Digest. Without NodeCrypto.layer, the test cannot reach the resource-read assertion.

Provide the Digest layer for this test.
makeCodexReplayHarness requires Digest.Digest. The layer list has no digest provider. CI fails with Service not found: effect/crypto/Digest. Add NodeCrypto.layer. The file already imports @effect/platform-node/NodeCrypto.

Use the current thread settings when recovery resumes Codex.
withLoadedThread closes over input.modelSelection and input.runtimePolicy from openSession. Later turns can change the model or runtime policy. Recovery then sends the stale model and cwd in thread/resume. The thread can reload with settings that differ from the current ones. Pass the current model selection and runtime policy into recovery. If the MCP app interface cannot supply them, omit model and cwd from the resume params. Then Codex keeps the thread's stored settings.

Remove the duplicate isCodexAppServerRequestError declaration.
Line 353 already declares isCodexAppServerRequestError at module scope with the same Schema.is(CodexErrors.CodexAppServerRequestError) value. This line adds a second local binding that shadows it. The shadow does no harm, but it adds noise. Delete this line and use the module-level predicate.

Use resumeNativeThread for MCP recovery.

If an unloaded thread was archived elsewhere, the direct resume can fail with an archive error. The MCP operation then fails instead of unarchiving and retrying the thread.

Fix the formatting of the Layer.mergeAll call.

The CI lint job fails in vp check because of a formatting error. Line 6768 puts all four layers on one line and has no space after NodeServices.layer,. The NodeCrypto.layer addition from the earlier review is correct. Put each layer on its own line, or run vp check --fix.
