Codex app-server protocol "serverRequest/resolved" requestId itemId JSON-RPC

💡 Result:

<search_synthesis>
In the Codex app-server protocol, serverRequest/resolved is a server-initiated JSON-RPC notification used to inform the client that a previously issued server-to-client request has been finalized [1][2][3]. Protocol Details: 1. Server-Initiated Request: The server initiates a request (e.g., item/commandExecution/requestApproval or item/tool/requestUserInput) to the client, providing a unique requestId, itemId (if applicable), and context params (threadId, turnId) [1][4][5][3]. 2. Client Response: The client responds to the original JSON-RPC request ID with its decision or user input [1][4][3]. 3. Completion Notification: Once the server processes the client&#39;s response, it emits the serverRequest/resolved notification [1][6][3]. This notification acts as an acknowledgment that the lifecycle of the specific request has ended [7]. Key Fields in serverRequest/resolved: - threadId: The identifier for the conversation thread [5][7][8]. - requestId: The unique identifier matching the original request [4][5][7]. This notification is critical for clients to clear pending states in their UI, such as closing an approval dialog or hiding a user input prompt, after the server has acted upon the user&#39;s input [7][8]. Clients typically correlate these events using the requestId [7].

<title>codex app-server emits approval requests but lacks a strict approval response RPC</title> GitHub issue 14192 in openai/codex (link omitted to avoid creating a cross-reference) # codex app-server emits approval requests but lacks a strict approval response RPC - State: closed - Author: Wheels00 - Created: 2026-03-10T06:43:11Z - Updated: 2026-03-10T16:08:21Z - Repository: openai/codex - Number: `#14192` ## Labels - bug - sandbox --- ## Summary `codex app-server` appears to emit approval request notifications, but in strict protocol-only mode it does not expose a usable approval response RPC for the controller to call back into. When fallback/emulation paths are removed, live approval flows fail with: `Approval RPC method is not supported by the connected bridge.` ## Environment - Codex LAN controller repo driving `codex app-server` - Date observed: 2026-03-10 - Controller configured for strict protocol-only approval handling - Live suite run against a fresh isolated controller/state, not a reused background process ## Reproduction 1. Start a fresh controller instance that launches `codex app-server`. 2. Use a prompt that triggers a command approval, for example: `Use the shell to run \`open -g -a Calculator\`. If approval is required, request it and then continue after approval. When complete, reply with exactly DONE.` 3. Wait for the real approval request event. 4. Call the controller approval endpoint, which forwards to the discovered upstream approval responder: `POST /api/thread/:id/approvals/respond` 5. Observe the upstream response behavior. ## Expected behavior If `codex app-server` can emit a real approval request, it should also expose at least one real approval response RPC that clears the pending approval state. Examples of protocol shapes a controller can support: - `approval/respond` - `approval/resolve` - `approval/approve` - `approval/reject` - equivalent permission/turn-scoped variants The important part is that there is a documented, supported RPC path for approving or rejecting a pending approval request without local fallback emulation. ## Actual behavior In strict protocol-only mode, the controller cannot find a supported upstream approval response RPC. The live flow fails with: `Approval RPC method is not supported by the connected bridge.` Before removing fallback discovery, the controller could also discover `command/exec:callId:decision`, but that behaves like a fallback/emulation path rather than a real approval contract and does not satisfy strict protocol-only approval handling. ## Why this matters Controllers built on top of `codex app-server` need deterministic approval semantics: - request event appears - user approves or rejects - controller calls one supported upstream approval RPC - approval resolves or rejects deterministically Without a real response RPC, downstream integrations either: - cannot support approvals reliably, or - must reintroduce local fallback/emulation behavior that breaks the protocol contract ## Additional notes - This was tested after isolating the live harness so it no longer reused stale controller processes or state files. - Deterministic local/fixture tests pass on the controller side. - The remaining blocker is upstream approval response protocol support from `codex app-server`. ## Timeline - github-actions[bot] added label "bug" - github-actions[bot] added label "CLI" - github-actions[bot] added label "sandbox" - etraut-openai removed label "CLI" **etraut-openai** commented on 2026-03-10T16:08:21Z: > Thanks for the report. I don’t think this is a missing app-server API. > > For `turn/start` flows, approvals are modeled as server-initiated JSON-RPC requests, not as a separate client-invoked `approval/*` RPC. The public v2 contract is: > > 1. Server sends `item/commandExecution/requestApproval` > 2. Client shows approval UI > 3. Client replies to that same JSON-RPC request id with a normal result payload like `{ "decision": "accept" }`, `{ "decision": "acceptForSession" }`, `{ "decision": "decline" }`, etc. > 4.…[truncated] <title>messages.rs - source</title> https://docs.rs/codex-codes/latest/src/codex_codes/messages.rs.html 3//! The Codex app-server speaks JSON-RPC where every message carries a 4//! `method` discriminant alongside a free-form `params` blob. This module 5//! lifts that loose envelope into closed enums — [`Notification`] for 6//! server-initiated notifications and [`ServerRequest`] for server-initiated 7//! requests (the approval flow).

Correlate approval resolutions with the original JSON-RPC request ID.

CodexAppServerIncomingRequest.id is separate from payload.itemId, but handleServerRequest currently passes only the decoded payload to its handler. The permission handler therefore keys approvalCorrelationsRef by payload.itemId. serverRequest/resolved.params.requestId identifies the original server request, and these values can differ. A missed lookup leaves the emitted resolution without the canonical requestId or requestKind, so Allow, Deny, or Stop can leave the pending approval unresolved.

Expose request.id through handleServerRequest in packages/effect-codex-app-server/src/client.ts. Use its normalized value for the permission handler's jsonRpcId and approvalCorrelationsRef. Update codexCollabMockPeer.mjs to emit the original wire ID and assert that ID in the integration test.
