fix(codex): approvals still appear after many stopped Codex turns#23242
Problem
Each Stop while a Codex approval is pending leaves one request handler waiting forever. The Codex transport allows 32 active handlers per app-server, and all Codex threads on a provider instance share one app-server. After 32 such Stops, every later approval, question or elicitation from any thread on that instance is refused with -32001 "Too many Codex requests are already active." The user sees no approval card. Codex records the command as failed and the agent carries on as if it was denied.
The handler waits on a decision that only a user answer resolves. After Stop the request is cancelled and can't be answered, so the answer never comes. Codex itself settles the request when the turn ends and sends serverRequest/resolved {threadId, requestId}, but the transport ignored that notification.
On main, sending another message in the same thread declines the stale card and frees the slot. Stops spread across threads leak, which is what happens when a parent cancels delegated Codex tasks (#21935). Once #22023 withdraws stale cards on Stop, the same-thread path would leak too.
Change
packages/effect-codex-app-server/src/protocol.ts:
- Request handler fibers now run in a
FiberMapkeyed by request id instead of a bareforkIn. The map lives in the samerequestHandlerScope, so protocol termination still interrupts every handler. Finished handlers leave the map on their own. - On
serverRequest/resolved, the matching handler is interrupted. No reply is written, because Codex already settled the request. The existingensuringreturns the slot, and the adapter's ownensuringdrops its pending entry.
The notification is still forwarded to onNotification as before. Codex also sends it after a normal answer, by which point the handler has finished, so that case is a no-op. This covers every server request kind and every way Codex ends one, not only Stop.
One side effect: if a stale card is still on screen after Codex settled its request, answering it now fails with "No pending Codex runtime request". Before, the reply went to Codex, which ignored it.
Scope and approval
Fixes the adapter half of #21935, which @juliusmarminge accepted as a bug. #22023 by @fixfon fixes the projection half and lists this leak under Risks ("Codex's approval handlers wait without an abort"). That PR touches different files.
Verification
New test in protocol.test.ts: 32 approval requests whose handlers never finish, then a serverRequest/resolved for each, then request 33. It expects request 33 to be handled. It fails on main with the -32001 refusal and passes here, with the other 15 protocol tests.
The new protocol test fails on main with the -32001 refusal and passes on this branch
Real app: production builds of main and this branch, fresh state, real Codex CLI 0.163.0 pointed at a local Responses API stub, so no account was used. In 33 new Supervised threads on one Codex instance, each asks to run touch approved.txt. In threads 1 to 32 the approval card shows, and Stop is pressed without answering.
Main, thread 33: no approval card. The turn ends by itself with "Done."
Main: thread 33 shows no approval card and the turn ends with Done.
This branch, thread 33: the approval card shows.
This branch: thread 33 shows the command approval card
Pressing Approve runs the command, and the file is created.
This branch: after Approve, thread 33 finishes with approved.txt changed
Codex app-server traffic for the same runs: main answers request 32 with -32001, and this branch forwards the user's accept.
App-server traffic: main refuses request 32, this branch sends accept
A direct probe of codex app-server 0.163.0 (three turns, each interrupted with an approval pending) received serverRequest/resolved for each request.
Also run on this branch, in packages/effect-codex-app-server: protocol.test.ts and client.test.ts (18 passed), tsc-rs --noEmit, and vp lint and vp fmt --check on both changed files. All passed.
Not checked
- Codex versions older than 0.163.0. The notification is in the generated protocol schema this package already uses.
- A real model account. The stub only returns the tool call that triggers the approval.
- Other request kinds (file change, permissions, MCP elicitation, user input) in the real app. They share the same transport path, which the protocol test covers.
Prior PRs
- #22023 by @fixfon (open) withdraws a stopped turn's pending approvals in the projection and named this leak. Nothing reused; the two fixes are independent.
- #22982 by @juliusmarminge (open) cancels approval-blocked tools when a run ends. It says the #21935 Stop path is not fixed there, and it touches different files.
- #18764 by @SunkenInTime and #12777 by @VendettaGhub (both open) change
protocol.tstermination handling in other hunks. - Issue #21935 reported by @eowca.

Approvability
Verdict: Approved at 47d82f5
Macroscope's review found this PR approvable â This focused Codex protocol fix releases handler fibers when Codex has already settled a request, preventing stale approvals from exhausting the 32-handler limit. It includes a regression test for the exhausted-handler scenario and leaves normal completion and termination behavior scoped as before.

| 398 | # FiberMap.run, FiberSet.run, and FiberHandle.run ignore startImmediately: false |
| 399 | |
| 400 | ## What version of Effect is running? |
| 401 | |
| 402 | `effect@4.0.0-rc.117` (the latest published v4 RC when checked). Also reproduced on `4.0.0-rc.112`. |
| 403 | |
| 404 | Runtimes tested on rc.117: Bun 1.2.21 and Node.js v24.7.0, macOS arm64. |
| 405 | |
| 406 | ## What steps can reproduce the bug? |
| 407 | |
| 408 | In a new directory, install the exact version: |
| 409 | |
| 410 | npm init -y |
| 411 | npm install --save-exact effect@4.0.0-rc.117 |
| 412 | |
| 413 | Save the following as `repro.ts` and run `bun repro.ts` (or `node repro.ts` with Node.js v24.7.0): |
| 414 | |
| 415 | import { Effect, FiberMap } from "effect" |
| 416 | |
| 417 | const program = Effect.gen(function* () { |
| 418 | const map = yield* FiberMap.make<string>() |
| 419 | const log: Array<string> = [] |
| 420 | |
| 421 | yield* FiberMap.run(map, "a", Effect.sync(() => log.push("a started")), { startImmediately: false }) |
| 422 | log.push("run(a) returned") |
| 423 | |
| 424 | yield* FiberMap.run(map, "b", Effect.sync(() => log.push("b started")), { startImmediately: true }) |
| 425 | log.push("run(b) returned") |
| 426 | |
| 427 | // Control: forkChild honors startImmediately: false. |
| 428 | yield* Effect.forkChild(Effect.sync(() => log.push("child started")), { startImmediately: false }) |
| 429 | log.push("forkChild returned") |
| 430 | |
| 431 | yield* Effect.yieldNow |
| 432 | return log |
| 433 | }) |
| 434 | |
| 435 | Effect.runPromise(Effect.scoped(program)).then((log) => console.log(log.join("\n"))) |
| 436 | |
| 437 | ## What is the expected behavior? |
| 438 | |
| 439 | If `run` accepts `startImmediately: false`, it should defer starting the new fiber: `run(a) returned` should appear before `a started`, as with `Effect.forkChild`. |
| 440 | |
| 441 | Alternatively, if synchronous startup is intentional, remove the unsupported option from the public `run` types. The choice of API behavior is up to the maintainers. |
| 442 | |
| 443 | ## What do you see instead? |
| 444 | |
| 445 | Both runtimes print: |
| 446 | |
| 447 | `a started |
| 448 | run(a) returned |
| 449 | b started |
| 450 | run(b) returned |
| 451 | forkChild returned |
| 452 | child started |
| 453 | ` |
| 454 | |
| 455 | The option does not change startup behavior. Whenever `run` launches a new fiber, it starts it synchronously, whether `startImmediately` is false, true, or omitted. |
| 456 | |
| 457 | ## Additional information |
| 458 | |
| 459 | The same behavior was verified for `FiberSet.run` and `FiberHandle.run`, with both curried and uncurried calls. A separate matrix checked all four APIs (`FiberMap.run`, `FiberSet.run`, `FiberHandle.run`, and the `Effect.forkChild` control), both call forms, and false/true/omitted options: 24 cases per runtime. |
| 460 | |
| 461 | In the published rc.117 source, all three public APIs accept `startImmediately`, but their `runImpl` options types omit it. Each implementation calls `Effect.runForkWith(parent.context)(effect)` without forwarding startup options (omitting the source's context cast here for brevity). |

Preserve the request ID type in FiberMap keys.
JsonRpcId accepts both numbers and strings, and isIncomingRequest admits both types. Active requests with IDs 1 and "1" can therefore reach this map. String(request.id) maps both IDs to "1". FiberMap.run interrupts the existing handler, whose interruption does not enter either response branch. The first request may receive no response. The serverRequest/resolved lookup has the same collision.
đ Suggested key change
| 1 | - FiberMap.run(requestHandlers, String(request.id)), |
| 2 | + FiberMap.run(requestHandlers, `${typeof request.id}:${request.id}`), |
| 3 | - ? FiberMap.remove(requestHandlers, String(notification.params.requestId)) |
| 4 | + ? FiberMap.remove( |
| 5 | + requestHandlers, |
| 6 | + `${typeof notification.params.requestId}:${notification.params.requestId}`, |
| 7 | + ) |

Verified in a real dev environment
verified as-is at 82f1d04fa3fbcff0f3190bc89f7120e7b7fcadf4 on this Linux Boat VM. compared with github/main at 6575ce32508bd7908444241f3719aa33aaf77f90. installed both with vp i and ran one isolated dev server at a time. drove the actual web app using repo Playwright and /usr/bin/google-chrome, with real Codex CLI 0.164.0, model gpt-6.1-sol, through the local proxy. no model stub, replay provider, fixtures or database edits.
added a project for a real git repository through the app. in 32 separate supervised threads, sent the same prompt to run touch approved.txt, waited for the approval card, then clicked Stop without answering. provider logs confirmed serverRequest/resolved after every stop. main needed thread reloads to display cards.
main request 33 received -32001, showed no approval card, and did not create the file. on the exact pr head, request 33 displayed the card; clicking Approve sent accept, created approved.txt, and finished with the successful command and changed file visible.
neighboring checks also passed: declining request 34 sent decline and left declined.txt absent; approving request 35 sent accept, created approved-again.txt, and completed. the same shared codex app-server stayed running throughout each 33-thread run.
short transcript from the running server and filesystem:
| 1 | main: 32 approvals stopped; 32 serverRequest/resolved notifications |
| 2 | main request 33 (id 32): {"error":{"code":-32001,"message":"Too many Codex requests are already active."}} |
| 3 | main: approved.txt absent |
| 4 | pr: 32 approvals stopped; request 33 card visible |
| 5 | pr request 33 (id 32): {"result":{"decision":"accept"}} |
| 6 | pr: approved.txt exists; turn completed |
| 7 | pr request 34 (id 33): {"result":{"decision":"decline"}}; declined.txt absent |
| 8 | pr request 35 (id 34): {"result":{"decision":"accept"}}; approved-again.txt exists |
| 9 | pr total: 35 requests, 35 resolutions, 0 overload responses |

no source changes were needed. existing ci reports 27 successful checks. inspected the captures and verified uploaded video playback through the end, seeking and resuming.
main request 33: approval failed and the command did not run
pr request 33: approval available after 32 stopped approvals
pr request 33: approve runs the command and shows approved.txt
Not verified
git.cafe renders the external evidence embeds as links. the uploaded originals were inspected directly, and the mp4 played through to completion with seeking/resuming checked in Chrome. inline playback inside the pr comment was not available.
native iOS/Android and Electron shell behavior, macOS/Windows, remote relay/tunnel connections, older Codex versions, and other server-request kinds such as file-change approval or elicitation were not exercised on this Linux web-client run. numeric/string request-id isolation and termination behavior were covered by the existing focused protocol tests, not separate real-provider scenarios.
stale approval-card withdrawal is outside this pr; stopped cards can remain visible. this run verified transport handler release.
