Directory updates dropped during in-flight sync
Medium Severity
requestDirectoryRefresh returns immediately when directorySyncTask is already running, and directorySyncFinished never checks wantedDirectoryRevision or starts another fetch. A directory.changed notification that arrives after the in-flight load has already committed can leave the cache on an older revision until the next permission-expiry maintenance pass.

Inline comments:
In `@cmuxTests/MobileHostAuthorizationTests.swift`:
- Around line 122-127: Remove the global MobileHostPublicStatusCache route
installation from MobileHostAuthorizationTests.swift lines 122-127, or place
both suites under one shared serialization scope. In
MobileHostWorkspaceTicketAuthorizationTests.swift line 345, update
createAttachTicket to use an injected empty route source instead of relying on
MobileHostPublicStatusCache.removeAll() to establish the noRoutes precondition.
In `@ios/cmuxPackage/Sources/cmuxFeature/MobileIrohV2Configuration.swift`:
- Around line 51-57: Update MobileIrohV2Configuration.current’s environment
resolution to accept only production, staging, and development; for any
unsupported override, fall back to defaultEnvironment and derive baseURL from
that resolved value rather than selecting development.
- Around line 58-61: Update MobileIrohV2Configuration.current to treat an
invalid persisted CMUX_IROH_V2_BASE_URL as unusable: remove the persisted
override, fall back to the derived origin, and retain the HTTPS and non-nil host
validation without trapping during app startup.
In `@ios/cmuxPackage/Sources/cmuxFeature/MobileIrxDiscoveryProvider.swift`:
- Around line 57-63: Consolidate directory projection updates in
MobileIrxRuntimeComposition through a single method keyed by directoryScopeID()
and directory.revision; reject revisions older than the last applied revision so
stale observations cannot overwrite newer discovery results. Remove
observedDirectory as a parallel state owner, route observe(_:) and
discoverLiveMacs() through the shared scoped state path, and add an interleaving
test covering an old observation resuming after a newer discovery.
In `@ios/cmuxPackage/Sources/cmuxFeature/MobileIrxRuntimeComposition`+Dial.swift:
- Around line 11-12: Remove the per-peer dial-intent lookup used by peerTarget
and dialOnce, and keep each request’s resolved intent as the single source of
truth. Thread that intent through engine(forPeer:)’s dial closure into
ensureSession and the eventual dial call, while retaining activeDialIntentByPeer
only to record the intent used to establish the current session. Preserve the
existing automatic/direct behavior without relying on shared mutable state
between suspension points.
In
`@ios/cmuxPackage/Sources/cmuxFeature/MobileIrxRuntimeComposition`+Streams.swift:
- Around line 12-15: Update serverEventByteStream to release the claimed event
session from its onTermination handler, using peerHex and the admitted session
ID as guards so a newer claim is not removed. Add or reuse a releaseEventClaim
helper for the guarded removal, and make occupied claims return
IrxConnectionError.closed(nil), matching claimControlLane.
In
`@ios/cmuxPackage/Sources/cmuxFeature/PersonalIrohDeviceRegistryDecorator.swift`:
- Line 32: Update the PersonalIrohDeviceRegistryDecorator flow to accept and
retain the preferredTag already supplied to MobileIrxDiscoveryProvider, then
pass that value to catalog.liveMacCandidates(preferredTag:) instead of the
literal "default". Preserve the existing device-list ordering behavior while
honoring the install’s preferred build tag.
In
`@Packages/iOS/CmuxMobileShellUI/Sources/CmuxMobileShellUI/MacComputerDetailView.swift`:
- Around line 723-726: Update the direct-connection help alert and its
mobile.connections.direct.addMessage localization to state that an explicit port
is required, replacing the outdated claim that the advertised port is used when
omitted. Keep the text consistent with parseDirectAddress, the placeholder, and
footer copy.
In
`@Packages/Shared/CmuxAuthRuntime/Sources/CmuxAuthRuntime/Coordinator/AuthCoordinator`+TeamScopes.swift:
- Around line 7-8: Update authenticatedTeamScope and the team-refresh state in
AuthCoordinator so team membership is tied to the current sessionGeneration:
clear or fence membership before publishing a changed session, record the
generation only after refreshTeams succeeds, and return nil when the recorded
generation does not match the current generation. Keep selectedTeamID as a
preference and apply it only after authoritative availableTeams membership has
been established.
In `@Packages/Shared/CmuxIrxTransport/Sources/CmuxIrxTransport/IrxEndpoint.swift`:
- Around line 181-183: Update rotateCredentialsIfCurrent to validate rotation
ownership, then enqueue credentials through relayInstaller instead of calling
driver.insertRelay directly. Make relayInstaller the shared source of truth for
desired and installed credential state, while preserving the rotation-generation
gate in the shared installation path.
In
`@Packages/Shared/CmuxIrxTransport/Sources/CmuxIrxTransport/V2/V2ControlService.swift`:
- Around line 255-258: Update the shared success path in perform so that,
immediately after successfully decoding Response, it clears failure together
with cooldowns and retiredAttempts for schemaID. Remove any duplicate common
success bookkeeping from operation wrappers while preserving their
operation-specific cache updates.
In
`@Packages/Shared/CmuxIrxTransport/Tests/CmuxIrxTransportTests/IrxLivenessTests.swift`:
- Around line 46-49: Replace the fixed Task.sleep in IrxLivenessTests with a
real transport signal: resume the application, then use waitUntil to wait for
the next pong before asserting. Verify the miss counter remains zero and
probeCount advances exactly once, preserving the ordering that demonstrates no
strike occurred during suspension without relying on elapsed time.
- Around line 97-98: Remove the measured-duration assertions around the liveness
recovery checks, including the elapsed calculations and hard two-second ceilings
in both call sites. Keep the preceding waitUntil recovery checks and the
following journal-record assertions unchanged.
In `@Sources/Auth/MacAuthComposition.swift`:
- Line 188: Update the sign-out flow around AuthCoordinator and
MobileHostIrxRuntime.shared.beginSignOutPreparation() to revoke the v2 device
registration using its device record ID, or an equivalent token-authenticated
endpoint, before stopping the v2 service. Ensure this revocation occurs before
local authentication is cleared and before beginSignOutPreparation() schedules
stopHost(), while preserving the existing onSignedOut cleanup.
In `@Sources/Cloud/ConnectivityInvalidationSubscriberCoordinator.swift`:
- Line 108: Update the invalidation handler around
MobileHostDiagnostics.logger.info and PhoneReplyInboxCoordinator.shared so
server-side invalidation also invokes MobileHostIrxRuntime.foreground(),
ensuring the v2 runtime republishes its route while preserving the existing
inbox sweep.
In `@Sources/Mobile/MobileHostService.swift`:
- Line 316: Update identityStatusPayload to require a non-nil value from
MobileHostPublicStatusCache.currentV2DeviceID() before returning authenticated
identity status; return a non-success result or retry identity adoption when
mac_device_id is unavailable, while preserving normal identity adoption once the
ID exists.
In `@Sources/Mobile/MobileHostTransportAuthorization.swift`:
- Around line 247-253: Update the public status cache clearing path,
specifically removeAll(), to also clear v2DeviceID using the existing
synchronization mechanism. Preserve current clearing of legacyRoutes and
irohRoute so currentV2DeviceID() cannot return a stale identifier after
MobileHostService.stop().
In `@Sources/Mobile/Pairing/MobilePairingModel.swift`:
- Line 214: The hard-coded reachableViaIroh value in the pairing readiness flow
must not be derived from ensureListeningAndReady(); expose the authoritative
V2ControlService registration snapshot through MobileHostServiceStatus and use
it to determine reachability. Keep pairing at .preparing or .failed until
registration is valid for the current authenticated scope and generation,
failing closed when that state is unavailable.
In `@workers/iroh-v2/e2e/control-runtime.test.ts`:
- Around line 154-157: Update the socket response assertions in the
control-runtime test to await promises that are created before each send and
resolve when the message event contains the expected schemaId. Replace the fixed
50 ms delays with a generous timeout used only as a failure deadline, so the
test waits for delivery rather than relying on wall-clock scheduling.
In `@workers/iroh-v2/scripts/deploy-dev.sh`:
- Around line 42-59: Update the secret handling around the deployment block so
secret values are passed to the Node writer through standard input rather than
process arguments, while preserving the generated JSON secret file consumed by
wrangler. Add an EXIT trap immediately after creating secret_file to remove it
on both success and failure, and remove the separate cleanup that becomes
redundant.
In `@workers/iroh-v2/src/storage/migrations.ts`:
- Around line 37-38: The update triggers in the migrations flow currently use
character length instead of UTF-8 byte length, allowing multibyte metadata to
bypass the storage limit. Add an immutable migration that recreates
devices_usage_update_guard and devices_usage_update_bytes using CAST(... AS
BLOB) length expressions, and add a regression test covering updates with
multibyte metadata.
In `@workers/iroh-v2/src/storage/team-store.ts`:
- Around line 205-208: In the pending-challenge transaction, delete expired rows
from pending_challenges before calculating count and enforcing the 4,096-entry
limit. Update the flow around the exists/count checks so active challenges
retain the current behavior while expired identities no longer consume capacity.
In `@workers/iroh-v2/src/team-control.ts`:
- Around line 189-200: Move the this.save call until after the authority,
expiry, and revision checks in the surrounding response-delivery flow complete
successfully, ensuring validation failures do not advance attachment delivery
state, outputRevision, or UserUsage before the response is sent.

Two independently serialized suites now mutate one process-wide route cache. Both tests moved from per-service listener state to the global MobileHostPublicStatusCache. @Suite(.serialized) orders tests inside a suite only, so the two suites can run in parallel and one suite's route installation can invalidate the other suite's noRoutes expectation.

As per coding guidelines for test files: "Order-dependence on shared static / global / UserDefaults / file state that is not reset per test" is disallowed.

Reject unsupported CMUX_IROH_V2_ENVIRONMENT values. MobileIrohV2Configuration.current preserves an unknown override but selects the development Worker in the default branch. A release build can therefore send Iroh traffic to development. Resolve only production, staging, and development; otherwise use the build-derived defaultEnvironment for both environment and baseURL.

Use one authoritative directory projection path.
observe(_:) now updates routeCatalog independently from discoverLiveMacs(). Main-actor reentrancy permits an old observation to resume after a newer discovery and replace the catalog last. The scope check does not reject an older directory.revision.
This can restore stale devices and routes until another update occurs. MobileIrxRuntimeComposition must own the scoped directory state.
As the first migration cut, route all catalog updates through one method keyed by directoryScopeID() and directory.revision. Reject revisions older than the last applied revision. Remove observedDirectory as a parallel state owner. Add an interleaving test that resumes an old observation after a newer discovery.
As per coding guidelines: “The same behavior wired separately through multiple surfaces instead of one shared action path.” As per path instructions: “Use authoritative structured state for v2 identity, team scope, listener lifecycle, directory, admission, and connection status.”

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Pass the dial intent through the dial call instead of a per-peer mutable dictionary.
peerTarget writes dialIntentByPeer[identity.endpointID], and dialOnce reads the same key later at Line 50, after several suspension points. Two concurrent requests for the same peer that carry different intents overwrite each other. The request that asked for .automatic can then execute the .direct branch and fail with directDialUnavailable, while activeDialIntentByPeer records an intent that no longer matches the caller. The engine recovers on the next attempt, so the symptom is an avoidable dial failure rather than a wrong path policy.
The structural root cause is that the request already carries the intent, but the composition stores a second copy in shared mutable state keyed only by peer. The request should stay the single source of truth for its own intent: thread the resolved intent into engine(forPeer:)'s dial closure and into ensureSession, and keep activeDialIntentByPeer only as the record of what the current session was established with. That change makes the whole class of "intent overwritten between request and dial" bugs impossible.
Based on coding guidelines requiring that Swift changes avoid "a new mutable flag, cache, singleton, observer, or side channel that creates another owner for state already owned by a model, actor, store, view coordinator, or persistence layer".

Swift AsyncThrowingStream Continuation onTermination finish documentation
💡 Result:
The onTermination property of an AsyncThrowingStream.Continuation is a callback closure that is invoked when the stream’s iteration is cancelled [1][2]. It allows you to perform necessary cleanup operations, such as stopping background monitors or releasing resources, when the stream is no longer being consumed [3][4]. Key behaviors include: 1. Timing of Execution: When task cancellation occurs, the onTermination callback is invoked first. Only after this callback returns does the stream proceed to yield nil or throw an error from the iterator [1][5]. 2. Lifecycle: After reaching a terminal state—whether via cancellation or a standard finish—the AsyncThrowingStream disposes of the callback [1][2]. 3. Threading and Deadlock: Because the system may trigger this callback as part of task cancellation, it is subject to the same deadlock-avoidance considerations as withTaskCancellationHandler(operation:onCancel:) [2][5]. 4. Termination Enum: The callback receives a Termination value, which indicates how the stream ended [2][5]: - finished(Failure?): The stream finished due to a call to the continuation’s finish method (with an optional error). - cancelled: The stream finished due to cancellation [2][4]. Example usage pattern: continuation.onTermination = { @Sendable termination in // Perform cleanup, e.g., stopping a monitor or timer myResource.stop } Note that while onTermination is specifically designed for cleanup during cancellation, the callback itself receives information about both standard finishes and cancellations [2][4]. The system automatically manages the callback's lifecycle, disposing of it once the stream has reached a terminal state [1].

Release the event-session claim when the stream terminates.
ensureSession reuses the live admitted session, while serverEventByteStream never closes that connection or removes claimedEventSessions. After EOF or an error, a retry can therefore hit the same-session guard and receive CompositionError.unsupportedRoute. Release the claim from onTermination, guarded by peerHex and session ID. Return IrxConnectionError.closed(nil) for an occupied claim, matching claimControlLane.

Wait for each matching socket response.
The fixed 50 ms waits can expire before Miniflare delivers the response. This makes both assertions dependent on CI scheduling.
Create the response promise before socket.send. Resolve it when the message event contains the expected schemaId. Use a generous timeout only as the failure deadline.
As per coding guidelines: “A test must not depend on real wall-clock time.”

Do not trap on a persisted base-URL override.
MobileIrohV2Configuration.current persists CMUX_IROH_V2_BASE_URL before validation. A later launch without the process environment reads the stored value and can reach preconditionFailure for values such as http://localhost:8787. ios/cmux/cmuxApp.swift calls this method during app startup, so the trap can prevent UI initialization. Remove an invalid persisted value and use the derived origin while keeping the HTTPS requirement.

MobileHostIrohRuntime still constructs it and the lifecycle extension still consumes its auth-state stream, so the app target has not compiled since the project-ID collision fix exposed the file. Restores the file at its pre-#12326 content and its project wiring.

Thanks, Aziz. This is merged and is now the realtime foundation for the follow-up work in PR #12706. That follow-up keeps |
* Restore the Iroh version-skew gate after IROH v2 The Tailscale version-skew gate required six tests in IrohTailscaleVersionSkewMacGateTests, but main has had two since merge 5839d6e dropped four of them. Port the two Stable listener tests to the v2 runtime. The legacy compatibility listener is now the cmux/mobile/1 dialect on the v2 endpoint, gated by the same pairing opt-in, so the tests assert that the explicit and historical settings allow Iroh networking and keep that dialect reachable. Expose the endpoint ALPN list and the legacy-dialect accept check from MobileHostIrxRuntime so the tests exercise the same code the accept loop uses. Retire the legacy TCP authorization tests. #12326 removed the Mac TCP listener and legacyPrivateNetworkListener, and #12754 removed them again after a merge restored them. Set the gate's expected count to four and record why in the script. Fixes #13683 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Select Tailscale Only in the pre-Iroh upgrade gate test #10437 made the automatic method strict: a pairing without an Iroh identity no longer falls back to its raw Tailscale route, and legacyMacWithoutIrohFailsClosedInsteadOfSendingBearerOverTCP asserts that. preIrohPairingContinuesOverItsExactTailscaleRouteAfterIOSUpgrade still assumed the old fallback, so it has failed since 7c3093e. The failure was hidden because the gate's Mac step failed first. The test now selects Tailscale Only for the migrated Computer and keeps every assertion: the reconnect succeeds over Tailscale only, carrying the exact host and port from the migrated grant. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Keep a pre-Iroh pairing's migrated Tailscale route dialable #10437 made the automatic method strict — no cross-method fallback — and that also dropped the one route a pre-Iroh pairing has: the exact raw Tailscale endpoint its device-local migration grant names. #11890 documented that this route must survive and taught the connect-time policy gate to keep it, but the reconnect route gate ahead of that gate still filtered it away, so the route never reached it. Pass the pairing's migration grant to storedReconnectRoutes for the automatic method. It applies only when the pairing advertises no authenticated route, so a pairing with an Iroh identity is unchanged and a pairing with no grant still fails closed, which legacyMacWithoutIrohFailsClosedInsteadOfSendingBearerOverTCP and rejectedIrohReconnectNeverDowngradesToRawTailscale both assert in the same release gate. This restores preIrohPairingContinuesOverItsExactTailscaleRouteAfterIOSUpgrade with no change to the test.

Problem
IROH interactions still depended on the legacy client/runtime paths and the old broker architecture. That prevented independent Cloudflare deployment, fresh storage, safe device identity enrollment, and bounded control delivery.

High Risk
Touches device enrollment, signed control-plane auth, relay credential rotation, and connection lifecycle logic where regressions would break pairing, team isolation, or reconnect behavior.
Overview
Introduces the native IROH v2 control-plane client in
CmuxIrxTransport: generated v2 wire models, aV2ControlServicethat owns WebSocket setup (with signed device proofs), optional HTTP recovery, ticket/relay/directory refresh, durable v2 cache + keychain identity storage, and a new GitHub Actions workflow to validate theworkers/iroh-v2backend and transport package.IRX connection behavior is tightened for mobile lifecycle: keepalive moves to shared liveness probes with app suspend/resume (
setApplicationActive), foreground recovery probes before redialing, and admission errors map remote close reasons more reliably. Endpoints gaindirect-onlymode (relays disabled), serialized relay credential installation with retry, and dialing that requires explicit direct addresses; relay credential semantics are updated for 30-minute lifetimes.Auth adds
AuthenticatedTeamScopeplus an async scope stream so long-running connection work can be invalidated on team or sign-out changes without reading credentials. Mobile core addsCmxIrohLocalSocketAddress(IPv4/IPv6 with required numeric port) and documents that v2 rejects direct-dial candidates without an explicit UDP port.Reviewed by Cursor Bugbot for commit 3277199. Bugbot is set up for automated code reviews on this repo. Configure here.
Summary by cubic
Replaces the legacy IROH broker and Mac runtime with a team-scoped v2 Cloudflare control plane and native Mac/iOS clients. Pairing now requires explicit Mac activation, while direct routes require numeric ports and bypass relays.
