Explanation
The description explains the main CodeRouter handoff and authentication changes and lists validation commands, but it omits the required Changelog, Proof, and Checklist sections. It also does not explicitly state the results or scope of the required checklist items.
Resolution
Add the required Summary, Testing, Changelog, Proof, and Checklist sections. Document test results and any unverified areas, provide a changelog line or state
none, explain why screenshots or a clip do not apply, and complete or explain each applicable checklist item, including socket relay authorization and review status.

Full details: Cmux Swift Blocking Runtime

Explanation
The PR adds shipped runtime synchronization in two production Swift paths.
CLI/cmux.swiftaddsreadCoderouterCapabilityOutput, which loops until a deadline, callsDarwin.poll, and usesusleep(1_000)while reaping the probed process.runCoderouterAliascalls this probe before the routed handoff.ControlClientAsyncTransport.swiftaddsTask.sleepto implement the CodeRouter completion timeout. These changes are outside test code and match the rule's polling and sleep failure conditions.Resolution
Replace the synchronous capability-probe polling loop with a cancellation-aware asynchronous readiness/process-exit mechanism that resumes on pipe readiness, EOF, process exit, or timeout. Replace the
usleepreap loop with an explicit process-exit signal or cancellation-aware process waiter. Remove the productionTask.sleepcompletion task and use the reader's existing deadline-aware readiness path or another documented cancellation-aware scheduler to finish the continuation when the completion deadline expires.
Full details: Cmux Algorithmic Complexity
-
Explanation
coderouter/src/status.rs:105-108adds a repeated full scan ofaccountsfor every provider. The function first buildsprovidersfrom the API-provided accounts, then runsaccounts.iter().filter(...)inside the provider loop. This is O(A×P), and can become O(A²) when accounts contain many provider values.run_accountscalls this production renderer atcoderouter/src/cli.rs:678-687. The account list has no explicit small bound or benchmark, so this violates the nested-scan rule for paths that may handle about 1000 user-owned records.Resolution
Group the API-provided accounts once by provider with a dictionary or one-pass reducer, while preserving the required display order. Render each provider from its grouped slice. Also avoid
providers.containsatcoderouter/src/status.rs:68by inserting provider keys into the same grouping structure. This changes the account traversal from repeated scans to O(A) grouping plus O(A) rendering.

Explanation
The PR adds independently testable CodeRouter handoff domain logic to the cmux app target.
Sources/Cloud/CodeRouterHandoffArmGrantStore.swiftimplements expiring grants, replay protection, peer-token checks, and session binding.Sources/Cloud/CodeRouterHandoffClient.swiftimplements an injected auth seam, credential-bearing HTTP minting, response validation, and lease parsing.Sources/TerminalController+SocketClientCapability.swiftadds strict handoff JSON parsing and arm processing. These are provider, auth, protocol, and state-transition logic, not AppKit or app-lifecycle glue. The Xcode diff adds the new Cloud files to the cmux app source phase, while the associated tests use@testable import cmuxincmuxTests. The existingCmuxControlSocketpackage extracts socket transport code, but it does not contain these new app-owned handoff components.Resolution
Create a small
Packages/macOS/CmuxCodeRouterHandoffSwiftPM target. MakeCodeRouterHandoffMintingits first public protocol and move the handoff lease value, injected auth/network seam, lease validation, arm-grant store, peer verifier, and strict handoff parsers into the package. MoveCodeRouterHandoffSessionBindingwith the grant store. Keep onlyAuthCoordinatorconformance,attachAuth, current-session reads, socket-worker dispatch, and other app-lifecycle composition inTerminalController. Add package tests for the extracted value, parsing, lease, verifier, and grant logic.
Full details: Cmux User-Facing Error Privacy
-
Explanation
The new production CodeRouter CLI exposes upstream diagnostics to cmux users.
coderouter/src/control_plane.rs:1122-1172reads an HTTP response body, extracts its upstreammessage, and places it inError::Backend;coderouter/src/lib.rs:49-55prints that error to stderr. cmux routescmux crmanagement commands to this executable and preserves stderr (CLI/cmux.swift:6157-6171, 5820-5845), which establishes a user-facing path. The newcoderouter/src/oauth.rs:45-59also prints the raw authentication error, andcoderouter/src/cli.rs:624-650prints organization/team IDs in command output without the user supplying those exact IDs. These violate the rules for raw upstream messages and unrelated team IDs.Resolution
Use fixed, product-safe error messages for all CodeRouter CLI failures. Do not copy HTTP response messages or bodies into
Error::Backend; map status and operation to allow-listed generic guidance and keep diagnostics in sanitized internal logs. Do not printdirect_erroror OAuth callback error values. Do not relay raw provider or child-process error text to stderr. Remove organization/team IDs from status, organization-list, and switch output unless the user explicitly supplied that exact ID. Also ensure the newsendV2Envelopepath never formats a raw socket response intoCLIError; return a bounded generic transport error instead.
Full details: Cmux Full Internationalization
-
Explanation
The PR adds production user-facing/API error text without localization.
Sources/TerminalController+SocketClientCapability.swift:660-720sends English messages such asSign in to cmux before arming a CodeRouter handoffandToo many CodeRouter handoff launches are pendingin handoff responses.Sources/TerminalController.swift:1719-1730adds more English response messages for invalid handoff requests. These strings have noString(localized:defaultValue:)call and no matching entries inResources/Localizable.xcstrings. The newcli.coderouter.handoff.*entries are translated for all nine existing locales, but they do not cover these response messages.Resolution
Route every new user-visible CLI error and CodeRouter socket/API response message through the localized API. Add stable keys to
Resources/Localizable.xcstringswith translated values for every locale already present in that catalog. Include at least the handoff-arm messages inSources/TerminalController+SocketClientCapability.swift, the handoff-completion messages inSources/TerminalController.swift, and the new directCLIErrortext inCLI/SocketClient+V2.swiftsuch asInvalid v2 request idandInvalid v2 response.

V2 errors lose terminal sanitization
Medium Severity
Plain-text ERROR: replies and invalid v2 bodies are now thrown as raw socket text. The previous path ran them through CLITerminalText.printable, so control characters no longer get stripped before they reach the terminal.

- Line 19: Update the runner declarations in
.github/workflows/coderouter-publish-npm.yml at line 19 and
.github/workflows/coderouter-publish-pypi.yml at line 19 to use the
trusted-publishing exception form recognized by
tests/test_ci_self_hosted_guard.sh, or allowlist both jobs in that guard.
Preserve GitHub-hosted runners for OIDC trusted publishing and provenance.
Review comments at @.github/workflows/coderouter-release.yml:
- Around line 150-153: Disable cache writes in the release build job by setting
save-if to false on the Swatinem/rust-cache step. Keep the existing workspaces
and key configuration so the job can still restore cached data.
Review comments at @CLI/cmux.swift:
- Line 3740: Update the response-reading loop that calls
configureResponseReceiveTimeout to use deadline-bounded readiness waits and
nonblocking reads, rather than changing the socket receive timeout. Keep
sendSingleFrame’s framing transition authoritative: accept exactly one complete
frame followed by EOF and reject extra bytes, preserving buffered data when the
peer closes before reading begins.
Review comments at @CLI/SocketClient+V2.swift:
- Around line 196-198: Update the response ID validation in sendV2Envelope to
allow an absent or null ID on the regular transport while still requiring a
matching ID for CodeRouter frames. Preserve rejection of any present, mismatched
ID.
Review comments at @cmuxTests/CLIAuthAliasTests.swift:
- Line 974: Update the assertion in the test for commandRequiresHandoff so
["add", "codex"] expects no handoff; leave the policy and other command
assertions unchanged.
Review comments at @coderouter/npm/bin/coderouter.js:
- Around line 33-38: Update the launcher’s exit handling after spawnSync: when
result.signal is present, re-raise it on the parent process so callers observe
the child’s signal termination; otherwise preserve the child exit status,
falling back to 1 when it is null.
Review comments at @coderouter/README.md:
- Line 20: Update the license link in the coderouter README to point to its
local LICENSE file or an absolute GitHub URL, so it resolves correctly both in
the repository and on PyPI.
Review comments at @coderouter/src/cli.rs:
- Around line 311-317: Move the resolve_real_codex() call in run_routed_codex
before control_plane::route_config_for_command() so missing or self-resolving
Codex executables fail before the one-use handoff lease is consumed; leave the
remaining routing flow unchanged.
Review comments at @coderouter/src/config.rs:
- Around line 9-11: Add Serde’s struct-level default behavior to Config’s
existing serde rename_all attribute so missing fields use Config::default()
during deserialization, while preserving camelCase naming.
Review comments at @coderouter/src/oauth.rs:
- Around line 87-89: Update the PTY relay in the OAuth login flow to forward the
user’s stdin to the PTY master using its writer, so interactive `codex login`
prompts can receive input while the existing output relay continues to stdout.
Review comments at @coderouter/src/tui.rs:
- Around line 59-62: Update choose_login_action so its non-TTY branch returns a
usage error naming --no-browser and --code instead of selecting Browser;
preserve the existing interactive login flow.
Review comments at
@Packages/macOS/CmuxControlSocket/Sources/CmuxControlSocket/Server/ControlClientAsyncTransport.swift:
- Around line 342-357: In ControlClientAsyncTransport.swift, update
currentLineIsWithinCodeRouterHandshakeLimit to find the line end incrementally
from a saved index using the framer’s bare-newline rule, and classify only while
currentLineMethodIsCodeRouter is undecided. In ControlClientLineReader.swift,
give currentLineIsWithinCodeRouterHandshakeLimit, codeRouterPermittedReadCount,
and inspectCurrentLineMethodIfNeeded one shared incremental bare-newline
line-end state, and skip method reclassification once the route is decided;
preserve the handshake cap and late-route scan behavior without rescanning the
full pending line on each chunk.
Review comments at @Sources/TerminalController.swift:
- Around line 1288-1305: Move the expensive `codeRouterPeerVerifier.isTrusted`
check for `trustedPeerAuditToken` onto the socket worker before the `v2MainSync`
hop. Keep the `withTrustedPeerConnectionAuthorization` critical section limited
to the peer-token check, process-start-time check, and response write.
Review comments at @Sources/TerminalController+SocketClientCapability.swift:
- Around line 102-112: Update `authorizedSocketCommand` to parse the CodeRouter
method once into a local value and use it for the handshake checks and
whitespace guard instead of calling the three parsing predicates repeatedly.
Reuse the parsed method at each affected branch, including the checks
corresponding to lines 112, 154, and 194.

Disable cache writes in the release build.
The release build job builds, signs, and publishes binaries. The job restores and saves a Swatinem/rust-cache cache. Other workflows that share the cache scope can write that cache, so a poisoned cache can reach the released artifacts. In the release job, set save-if: false or drop the cache.

Do not discard a valid reply when the peer closes.
When the server sends its response and closes before this iteration, macOS rejects setsockopt(SO_RCVTIMEO) with EINVAL. Unix-socket disconnection sets the shutdown flags that cause this rejection. (raw.githubusercontent.com)
configureResponseReceiveTimeout then closes socketFD and throws. The strict reader loses buffered response bytes or cannot observe the required EOF. Valid handoffs therefore fail depending on response/close scheduling. The existing readStreamLine accounts for this condition at Line 4519.
Let sendSingleFrame own the deadline and framing transition. Its invariant must remain: accept one complete frame followed by EOF, and reject extra bytes. First migrate this loop to deadline-bounded readiness waits and nonblocking reads. Add a deterministic test that queues the response and closes the peer before reading starts.
As per coding guidelines, the fix must name “the invariant, source of truth, or state transition”.

Update the response-reading loop that calls configureResponseReceiveTimeout to
use deadline-bounded readiness waits and nonblocking reads, rather than changing
the socket receive timeout. Keep sendSingleFrame’s framing transition
authoritative: accept exactly one complete frame followed by EOF and reject
extra bytes, preserving buffered data when the peer closes before reading
begins.

Change the ["add", "codex"] assertion so that it expects no handoff.
CodeRouterLaunchPolicy.commandRequiresHandoff checks only commandArgs.first against ["codex", "opencode", "pi"] (see Packages/macOS/CmuxControlSocket/Sources/CmuxControlSocket/Transport/CodeRouterLaunchPolicy.swift lines 10-13). For ["add", "codex"] the first element is "add", so the function returns false. This #expect therefore fails, and the test fails on every run.
The policy is correct and the assertion is wrong:
- On the Rust side,
parse_hidden_argsincoderouter/src/handoff.rsaccepts onlycodex,opencode, orpiasargs[4]. cli::runrejects all other commands when a handoff is requested.
If cmux armed a handoff for add codex, the Rust CLI would reject the launch. The test name also says "only exact top-level agent names use socket handoff". add codex is a management command and must not arm.

The PTY fallback does not forward stdin, so codex login cannot receive input.
The relay copies PTY output to stdout. No code writes the user's stdin to pair.master. If codex login waits for a keypress or a pasted value, it blocks forever. child.wait() has no timeout, so the CLI hangs. Use take_writer() and forward stdin to the PTY. If no input is needed, run codex login without a PTY and inherit stdio.

A non-interactive login should not choose browser login silently.
choose_add_action and choose_remove_account return a usage error when no TTY is present. choose_login_action instead returns Browser. A script that pipes stdin then starts a browser OAuth flow and waits for it. This behavior differs from the other menus. Return a usage error that names --no-browser and --code, as the other menus do.

Use the framer's bare-newline line end for the CodeRouter cap, and track it incrementally. Both readers find the line end with firstIndex(of: 0x0A), but framing does not treat a \r\n pair as a terminator. This causes two problems:
- Cap bypass. A valid JSON frame with an internal
\r\nis classified from a short ordinary prefix. The 4 KiB pre-JSON cap and the late-route scan never apply. The line buffers up to the general limit, and the<= 4_096check inauthorizedSocketCommandrejects it only after the full allocation and decode. - Quadratic cost. Each loop iteration rescans the whole pending line and reclassifies the method. As per path instructions,
.github/review-bot-rules/algorithmic-complexity.mdfails a rescan of the full buffer for each chunk.

Code-signature validation runs on the main thread while the authorization lock is held.
The body passed to withTrustedPeerConnectionAuthorization executes inside v2MainSync. It also runs under the OSAllocatedUnfairLock in SocketConnectionAuthorizationState. In that body, codeRouterPeerVerifier.isTrusted calls several Security framework functions:
SecCodeCopyGuestWithAttributesSecCodeCheckValiditywithkSecCSStrictValidateSecCodeCopySigningInformationcsops_audittoken
These calls can do IPC and on-disk signature validation. While they run, the main actor stalls. Every socket reader that calls isConnectionAuthorizationCurrent also waits on the same lock. This breaks the lock's documented contract ("every critical section is bounded and performs no file or Keychain I/O"). As per coding guidelines, a heavy synchronous operation on the main actor or an interactive path must move off the main actor.
The exact audit-token equality check already detects an exec or PID reuse. A trust decision made earlier for the same token therefore stays valid.
Fix:
- Call
isTrusted(trustedPeerAuditToken)once on the socket worker, before thev2MainSynchop. - Inside the lock, keep only the token check, the start-time check, and the write.

Classify the CodeRouter method once per command, not six times.
authorizedSocketCommand runs for every socket command. This includes high-frequency traffic such as terminal input and report_* telemetry. Lines 102-105 call isCodeRouterHandoffCommand, isCodeRouterHandoffBeginCommand, and isCodeRouterHandoffArmCommand. Each call does a full ControlRequestParser().lenientRequest(fromLine:) parse. Lines 112, 154, and 194 call the same three predicates again. A command that is not a CodeRouter command therefore pays six full JSON parses before normal authorization. A preauthorization line can be up to 4 MiB. processSocketLine then parses again for isCodeRouterHandoffCommand.
Parse the method once, store it in a local value, and branch on that value. The per-site whitespace guard can use the same value.

#18953's classification test expected `add codex` to arm the handoff, contradicting its own name ("only exact top-level agent names use socket handoff") and the launch policy. CodeRouter's handoff parser accepts only a provider name after `--`, and `add` does its own login without a handoff lease, so the policy is right and the expectation was wrong.

…tdio The two posix_spawn sites #18953 added in the CLI handed the child the calling Swift concurrency thread's signal mask, so a CodeRouter child could not receive SIGTERM or SIGWINCH (CLIAuthAliasTests: termination signal) and the exec/spawn signal-state guard failed. Set an empty mask and default dispositions on both, as the other CLI spawn sites do. The alias exec also decided which standard descriptors to pass on at spawn time, so a file the CLI had opened since launch could reuse a closed stdin and reach the child as an open one. Record the caller's standard descriptors at the top of main and pass on only those. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* Stop the CodeRouter line reader tests deadlocking the package run The CodeRouter reader tests added in #18953 handed each payload to a DispatchQueue.global writer and then blocked in an untimed poll(2). Swift Testing runs them in parallel on the fixed-width cooperative pool, so every pool thread could sit in poll while no thread ran a writer, and the whole CmuxControlSocket test run stalled until the 180s watchdog killed it. Queue each payload and EOF synchronously instead, with socket buffers large enough to hold the biggest fixture frame. The caps under test are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Answer v2 test requests with the request's id #18953 made the CLI reject a v2 response whose id differs from its request. The shared UnixSocketResponder and RelaySocketResponder fakes, and the capabilities handler in the socket deadline test, replied with canned JSON that carried no id, so about 50 CLI tests failed with "Mismatched v2 response id". Splice the request's id into canned v2 responses the way the app's ControlResponseEncoder does; v1 lines and responses that already set an id are left byte-for-byte.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Let browser eval test responses carry the request id Their canned responses set "id":null, which the CLI now rejects as a mismatched v2 response id.

* test(cloud): a full shared pool is not reported as a missing plan Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(cloud): explain a full shared pool instead of a missing plan A 402 vm_resource_pool_exceeded on a Pro team read as "Your plan does not allow this Cloud operation." because the client classified every 402 by status alone. Read the server's error code: a full pool names the vCPUs or memory in use and the request (reusing the sheet's pool shortfall copy), active-limit, create-credit and size-gated refusals get their own sentence, an unrecognised code keeps the server's message, and only a code-less 402 keeps the generic plan sentence. The pending create row offers Retry first and an upgrade second for a full pool. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(cloud): report a full pool as resource_limit and redact server copy Address review: the server's telemetry contract rejects an unknown failure class and drops the whole batch, so a full pool or active-limit refusal is classified as the existing resource_limit instead of a new capacity class. The open-workspace path now applies the same redaction fallback as create, and a full pool offers an upgrade only once the plan is known to have a higher tier. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(cloud): key create failure actions on the parsed refusal code Address review: the pending create row matched refusal codes as substrings of the display text, so a longer code such as vm_resource_pool_exceeded_v2 counted as a full pool. Read the code once from the exact (HTTP 402: <code>) reference the CLI and the in-process create both print, and compare it whole. Also translate the four new failure strings into every locale the catalog carries. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(cloud): carry the refusal code apart from the failure text Address review: reading the code back out of the failure text let a server message that named another code stand in for the real one. The in-process launcher now reads the code from the thrown error and the CLI path reads only the reference ending the CLI's own Error: header; both pass it through the create completion onto the operation, and the failed row's actions key on that carried code alone. A retry clears it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(cloud): cover the refusal code handoff to the failed row Address review: assert the app coordinator carries a launcher's refusal code onto the pending row and clears it on retry, that finish overwrites a code, and that an open failure on an existing machine keeps none.

The Changes panel's diff open (SupermuxFileDiffOpener -> bundled `cmux diff -`) failed about every other time since the cmux upstream sync (#106), the CLI exiting 1 with "Error: Socket closed before reply". Root cause: upstream's CodeRouter handoff guard (559a4f6, landed via manaflow-ai/cmux#18953) makes ControlClientLineReader classify every line by a top-level `method` key in its first 4 KiB (`codeRouterHandshakeMaximumBytes: 4_096`, Sources/TerminalController.swift) and close the connection unanswered when a longer line has none there. SocketClient.sendV2Envelope wrote the request with one JSONSerialization pass, in the dictionary's per-process hash order, so the ~82 KB `browser.open_split` request (its `diff_viewer_files` allowlist names every viewer asset) put `params` before `method` in about half of the CLI processes. The opener's arguments are fine; any CLI request over 4 KiB had the same odds (upstream issue manaflow-ai/cmux#21222). Fix (touchpoint #1257, `cli-v2-request-method-first`): sendV2Envelope writes `{"method":…}` joined with the remaining keys sorted. This ports the sendV2 part of Neha Chaudhari's open upstream PR manaflow-ai/cmux#21345 (`ControlRequestLine.encode`); its streamV2, hook feed.push and Pi compacted feed parts are not ported here. The server guard is unchanged. Green on the fixed tagged build order-sync, same command as the red commit 9af2865: CMUX_E2E_SUITES="loopback_workspace_behaviors_e2e" CMUX_TAG=order-sync \ tests/supermux/run_all_loopback_e2e.sh PASS: 28/28; file_diff_viewer_opens_for_remote_diff opened 8 of 8. Also: 20 clean-environment `cmux diff - --json --id-format uuids` runs through a logging socket proxy: 20/20 opened, 20/20 request lines start with {"method" (before the fix: 4 of 8 runs failed, the failing line starting with {"params").

Standalone replacement for Lawrence's #10194. This PR carries the native CodeRouter handoff into cmux and includes the authentication fix: provider commands reuse the signed-in cmux session instead of prompting the CodeRouter CLI to sign in again.
The async socket loop preserves the peer audit token and process start time, and the CLI classification regression covers

High Risk
Changes authentication and credential handoff over the control socket with code-signing gates and new release/signing pipelines; mistakes could weaken session binding or ship compromised binaries.
Overview
Adds end-to-end CodeRouter distribution and CI: Rust project scaffolding, PR/main CI (
fmt/clippy/test), tag-driven multi-platform release builds (native binaries, PyPI wheels, npm launcher), post-publish verification, and manual npm/PyPI trusted-publishing workflows. actionlint gains allowlisted ARM Linux and Windows runner labels used by the release matrix.cmux CLI no longer plain-
execs CodeRouter for every passthrough. Routed provider commands (codex,opencode,pi) probe for protocol v2, verify a signed, hardenedcoderouterbinary, then perform a capability-boundcoderouter.handoff.armover a 4 KiB single-frame socket exchange (peer audit-token / code-signing checks on macOS) and launch CodeRouter via hidden__cmux-handoff-v2argv with a scrubbed environment. Management/help paths stay direct exec without handoff.CmuxControlSocket captures peer audit token + process start time at accept, adds HMAC proof codecs and launch policy types, tightens line readers for handoff framing (one completion frame, fail-closed on late/oversized handoff routes), and exposes authorization helpers so credential-bearing handoff responses cannot race listener revocation.
