…s usable Failing regression for the advertise-before-ready warm-up race in #9724: start() publishes the binding and route hints while the relay credential is still installing, so clients burn doomed dials against a Mac that cannot accept them yet.
Fixes the warm-up race in #9724: start() serialized a live broker resolve, relay credential activation, and a relay wait while the Mac was already advertised, so phones burned 5-15 s of doomed dials on every launch. Cache-first: when the persisted last-good policy still cryptographically verifies for this exact account, device, endpoint, identity generation, and host settings (validateCachedPolicy), start() activates admission, attestation, LAN rendezvous, and the endpoint relay bootstrap from it immediately and returns active with no broker round. First launch, an invalid cache, and relay-only debug hosts keep the blocking resolve. Register-when-ready: handleBinding/handleRoute are never invoked with pre-relay state. When the home relay is not yet usable, a generation-guarded ready gate activates the relay coordinator, waits the bounded waitForUsableHomeRelay(), then runs one live reconcile through the existing coalescing refresh machinery, publishing fresh post-relay hints exactly once. A cached route identity is refreshed, never unpublished. A cache-first reconcile that finds its binding replaced server-side adopts the authenticated result in place: admission update already propagates the acceptor everywhere, and only the relay credential coordinator pins a binding id, so it is recreated. Renewal and requested refreshes keep failing closed on replaced bindings.
…fallbacks Behavior the client transport must have but does not yet (red on this commit, fixed in the next): - CmxIrohClientSession: an admission barrier that never answers must fail at the dial bound and be superseded by the next attempt (cmux#9724 16.2s dial, cmux#8531 silent redial hang). - CmxIrohRegistryContextProvider: when the staleness-forced discovery refresh fails, dial with the last verified snapshot instead of refusing to dial. - CmxIrohRelayPolicyService.restore: a recently-expired last-good policy must keep its routes dialable instead of publishing a zero-route managed profile (cmux#10375). - CmxIrohRelayCredentialCoordinator.refreshIfNeeded: a failed mint with a last-good installed credential must not throw; the bounded retry loop continues in the background (cmux#10375).
…failure, fail open on credential refresh Three client-transport behavior changes for iOS dialing (cmux#9724, cmux#8531, cmux#10375): 1. Bounded dials. The admission barrier after QUIC connect (control stream open, admission frames, NAT-traversal authorize, server ready) was unbounded; a half-ready Mac that accepts the connection and never answers admission produced the 16.2s hang in the #9724 trace. The barrier now runs under the same bounded race as the connect phases and fails typed as dialTimedOut, so the redial machinery supersedes it. The per-phase deadline is injected end to end: CmxIrohClientRuntimeConfiguration.dialPhaseTimeout (default 5s) -> CmxConnectivityEngine -> every CmxIrohClientSession. 2. Hint refresh fallback. A failed or timed-out dial already marks the peer's discovery stale and forces a broker refetch on the next attempt. When that refetch itself fails, the provider now dials the last verified snapshot's hints instead of refusing to dial; the staleness mark survives so a later attempt still refetches. Broker cooldowns still propagate unchanged when no last-good snapshot exists. 3. Fail-open credential refresh. CmxIrohRelayPolicyService.restore grants a bounded expired-policy reuse grace (default 6h, injectable): the cache re-verifies the record at its final valid instant, so signature, rollback, and claim checks run unweakened and only the expiry gate is graced; the graced state reports .policyExpired without zeroing routes. Beyond the grace or on any verification rejection, restore still fails closed. CmxIrohRelayCredentialCoordinator.refreshIfNeeded no longer throws on a failed mint while a last-good credential is installed; the bounded backoff retry loop keeps refreshing in the background and the relay stays the authority on token validity.
POST /api/devices/iroh/relay-token has zero callers: repo-wide grep for the path and its relay_token operation hits only the route file and web tests, and full-history git log -S over Packages/ Sources/ ios/ CLI/ cmux-tui/ daemon/ returns no commit in which any client referenced it. The Swift client has fetched relay credentials from POST /api/relay/token since the route was introduced in #7908. Removes the route dir, the relay_token IrohRouteOperation and dispatch, the public broker issueRelayToken (issueRelayTokenForBinding stays for the register bootstrap), its tests, and the stale README sentence.
Production has never set CMUX_IROH_MINT_URL / CMUX_IROH_MINT_HMAC_SECRET_B64, so every registration already took the mint-unconfigured branch and returned relay.status="unavailable"; clients get endpoint-bound fleet credentials from POST /api/relay/token instead. The only importers of the minter client (web/services/iroh/relayMinter.ts, minterUrlPolicy.ts) were trustBroker.ts, env.ts, and their tests; the Rust service services/iroh-relay-minter/ is in no Cargo workspace, package.json, or vercel config, and its only external reference was its own dispatch-only GitHub workflow. register now returns relay unavailable/not_requested directly, preserving the env-unset behavior exactly (minus the failed-issuance audit row). This deliberately removes the dormant n0-hosted fallback option; the registry / relay allow-hook path is the go-forward. Operational follow-up outside this repo: decommission the minter Vercel project and drop the two env vars from the web project.
…rror With the legacy relay-token route and the n0 minter gone, nothing calls IrohRepository.reserveRelayIssuance/completeRelayIssuance/failRelayIssuance (grep: definitions and their direct tests only), and the model constants IROH_RELAY_TOKEN_LIFETIME_SECONDS/IROH_RELAY_TOKEN_REFRESH_SECONDS have zero remaining users. IrohQuotaExceededError has had no producer since #9269 removed the broker quotas (grep for 'new IrohQuotaExceededError' hits nothing); its 429 mappings in the iroh and connectivity route handlers were unreachable. The iroh_relay_token_issuances table, its migrations, and the retention cleanup that drains historical rows all stay: production still holds rows.
…d iroh exports createOfflinePairSessionRecord / verifyAndConsumeOfflineSameAccountPair and their private helpers and types were added in #7908 but no route, broker method, or repository call ever reached them; repo-wide grep hits only crypto.ts and their unit test. The Swift offline-pairing feature verifies attestations peer-to-peer and never calls a server session endpoint. Also removes the constants that existed only for that subgraph (IROH_OFFLINE_PAIR_SESSION_*), serverPublishedIrohPathHints (zero references, not even tests), IROH_SIGNED_PATH_HINT_UPDATE_FOLLOWUP (its only occurrence is its definition; the literal string appears nowhere else, including Swift), and bindingMatchesDiscoveryScope from production (used only by the trust-broker test's in-memory repository, where it now lives as a local fixture helper).
Review P1: the ready gate caught the bounded readiness timeout together with every other error and then ran the publication refresh, recreating the discoverable-but-undialable race for any relay outage or warm-up slower than the readiness window. A timeout now keeps the endpoint unpublished and retries the readiness wait with bounded backoff on the injected registration clock, still under the lifecycle revision guards. Publication happens only after waitForUsableHomeRelay() verifies a usable relay path. Endpoint replacement or deactivation ends the gate unpublished and leaves state surfacing to the existing failure handling. The readiness window is now injectable (relayReadinessTimeout, default 15 s) so behavior tests can drive repeated timeouts without wall-clock waits.
The relay-required activation branch set publishInline directly. The readiness barrier had already completed there, so behavior was correct, but the special case made the guarantee non-obvious to review. Every path now re-checks verified readiness through initialPublicationReady() immediately before publication.
A network-change refresh can own the terminal round; its teardown can still be closing the endpoint when the publication pipeline await returns. The fail-closed assertions now wait bounded for the close.
The struct's only occurrence in the entire repo (all Swift under Packages/, Sources/, ios/, CLI/, daemon/, Native/, tests) is its own definition; no code constructs, returns, or names it, including the package's tests. swift build and swift test on the package pass after removal (615 tests in 66 suites; CmxConnectivityPeerSessionTests skipped because it deadlocks on current main independent of this change - the fix is in flight on origin/fix-peer-session-test-deadlock).
Review P1 pair: the deferred first publication could still ride any forced refresh (direct-port change, requested refresh) while the home relay was unusable, and a cache-first host whose relay never came up never verified its cached authority against the broker, hiding a server-side revocation or replacement behind a relay outage. Every refresh round now re-checks verified relay readiness immediately before performing the lifecycle's first publication; an unready round still applies admission policy, binding adoption, and renewal scheduling, and leaves the publication owed. A cache-first activation schedules its authenticated reconcile immediately, independent of relay readiness; a broker cooldown observed during activation keeps its validated retry floor, and the ready gate defers to an armed failure retry instead of preempting it.
Review P1: the relay-required deferred branch armed its registration retry without initialPublicationPending, so a retry round could perform the lifecycle's first publication without re-checking relay readiness. Every deferred first publication now carries the pending flag.
Commit 6cf5630 (#8567) declared worktreeDeviceID/worktreeFileID as 'let ... = nil', which removes them from the synthesized memberwise initializer, so the createWorktree call passing both labels failed to compile. Drop the defaults so the fields enter the memberwise init and the captured identity keeps flowing to rollback. Also unwrap the optional identity tuple in bestEffortCleanupFailedWorktree before comparing, since == is not lifted over optional tuples.
A multi-statement closure gets no implicit return, so the group.addTask closure returning Int32? failed to compile. Found while running the touched test class on the remote builder.
The startup ready gate task is armed with the cached binding and relay bootstrap it saw at activation. When the background reconcile adopts a server-side replacement binding, the stale gate could interleave with adoption and activate the replacement relay coordinator with the superseded binding ID and credential, breaking binding identity. adoptReplacedBinding now cancels and drains the stale gate before rebinding the relay coordinator, then re-arms the gate bound to the adopted binding and its bootstrap while the first publication is still owed, so the endpoint still publishes once the relay becomes usable. The new test covers adoption while the relay is unready end to end (cache-first start stays unpublished, adoption lands, exactly one publication of the adopted identity after readiness). The stale-activate interleaving itself is a scheduling window that a behavior-level test cannot pin deterministically, so this is hardening coverage, not a red-then-green regression pair.

The verb printed only the DiagnosticLog timeline; proving which relay the endpoint used required netstat. Append an active-relay section (managed catalog / custom / CMUX_IROH_RELAY_URL_OVERRIDE debug override, plus URLs) from a nonisolated mirror of the installed policy so the verb stays usable while the main thread is wedged. Relay URLs stay out of the privacy-safe DiagnosticLog report itself.

…Later deadlock AppTerminationRequest.schedule now defers NSApp.terminate to a main-run-loop callout (RunLoop.main.perform in common modes) instead of calling it inside the requesting block. A simulate_shortcut cmd+q handler runs inside v2MainSync's DispatchQueue.main.sync block; terminating there left the main queue occupied while applicationShouldTerminate's .terminateLater cleanup task waited for it, hanging the app forever. Fixes #10788.
POST /api/relay/report receives the cmux-relay Reporter's fire-and-forget
{endpointId, event, relayId, ts} events, HMAC-verified with the allow-hook
secret and hardened like /api/relay/allow (no-store, bounded body read,
apply deadline, dedicated deadline-bounded pool, concurrency cap). An
applied attach publishes the exact catalog or account-saved custom relay
URL onto the endpoint's binding; discovery then serves that server-observed
route ahead of client-published hints, so phones learn 'Mac X reachable via
relay Y' without the Mac's post-attach republish. Reports about relays
outside the catalog and the account's saved set are refused; out-of-order
events are dropped by relay-side timestamp with attach winning ties.
The Mac's post-attach republish stays as a gated fallback (rollout note in
CmxIrohHostRuntime.initialPublicationReady) until the reporting relay build
is deployed fleet-wide.
…ys detach P1: a relay that dies with its fire-and-forget detach report used to leave relay_attached_url served as fresh forever. Discovery now serves the attach route only while some live evidence is under an hour old: the attach report itself or the binding's lastSeenAt (a live Mac re-registers at least hourly; a Mac that outlives its relay reattaches elsewhere). P2: the trust lookup now gates only attach. A detach clears the stored attachment matched by hostname, so a custom relay deleted from preferences still detaches cleanly instead of leaving a stale route that would resurface if the relay were saved again.
The Reporter sends each event once with a 3s timeout and no retry, so a legitimate report is seconds old. Reports older than 15 minutes are now rejected, so a captured signed attach (the HMAC carries no nonce) can no longer be replayed into an empty attachment slot and served as current reachability.
Identity rides the iroh handshake and the relay's server-side allow hook (web /api/relay/token successor: /api/relay/allow, cmux-relay#9) is the only admission path, so the client-held 300 s relay tokens are dead weight. Deleted end to end: Swift (CmuxIrohTransport): - CmxIrohRelayCredentialCoordinator and its every-~4-minutes re-mint loop - CmxIrohRelayTokenResponse / ManagedRelayCredential / StoredRelayCredential / RelayConfiguration / RelayBootstrapResponse / RelayTokenServing / RelayRefreshSchedule / RelayEndpointControlling - token attach on managed connects: managed relay profiles are now built tokenless straight from the verified policy snapshot; custom relays keep user-configured static tokens - cachedRelayCredential plumbing in both runtime configurations, the handleRelayCredential persistence hooks, relay coordinator wiring in host/client runtimes, and the credential half of CmxIrohBrokerCredentialRepository (binding persistence stays) - TrustBrokerClient issueRelayToken/issueRelayBootstrap replaced by a credential-free fetchRelayPolicy() hitting GET /api/relay/policy web/: - /api/relay/token route, services/relay/token.ts minting, their tests, and CMUX_RELAY_JWT_PRIVATE_KEY_PEM; the signed relay policy now serves from the new credential-free GET /api/relay/policy App layer: - Mac host and iOS composition cached/fresh credential threading - the debug release-gate relay_rollover / relay_expiry scenarios, which existed only to verify credential rotation Registration keeps its wire-compatible relay status field; binding registration and discovery are untouched. Tests updated; new coverage proves the managed connect path builds no Authorization/token. REQUIRES the allow-hook fleet rollout (cmux-relay#9 deployed with dual-accept) before merge.
…tor mirror CmxIrohDebugRelayOverride keeps no new static members; the diag URL is read through an injectable CmxIrohDebugRelayOverrideDiagnostics struct in its own package file. The relay diag mirror moves to MobileHostIrohRuntime+RelayDiag.swift and becomes a revision-ordered actor instead of an OSAllocatedUnfairLock, read from the iroh_diag Task off-main so the wedged-main-thread guarantee is unchanged. AppTerminationRequest moves to its own Sources file.
…ility The actor mirror published through a detached Task, so an iroh_diag read racing a policy installation could report the previous or missing profile (second review round's finding). Restore the OSAllocatedUnfairLock mirror, now in MobileHostIrohRuntime+RelayDiag.swift: the didSet writer publishes synchronously before returning, and the reader stays off the main actor so the verb still works while the main thread is wedged. This matches the in-tree AgentChatThemeSync nonisolated-static-lock precedent; the Aziz lock-vs-actor lint intentionally stays flagged because an actor cannot give a synchronous writer read-after-write visibility here.
…t; doc the gated policy fetch The token-era build stored the relay credential under the scope key in the Keychain. saveBinding lost its invalidation delete in the token removal, so a replaced binding could strand that obsolete secret until sign-out. Restore the delete-on-change as legacy hygiene, with a regression test seeding a record at the exact scope key. Also adds the missing DocC line on CmxIrohBackpressuredRelayPolicyBroker.fetchRelayPolicy.
…file The default implementation silently succeeded for managed profiles after the token-era replaceRelays hook was removed, letting a supervisor commit a profile an alternate endpoint never applied. Reject unconditionally; concrete endpoints that support replacement override it.

Reproduces the Mac-host relay wedge from the 2026-08-26 itest sim timing batch: after an abnormal client death, the host stayed broker-registered and relay-attached, yet every new dial timed out until app restart. The accept pipeline performs the whole server-side handshake inline in the single serial accept loop, so one peer that stops making handshake progress blocks every later admission. Red on this commit; the fix lands in the next commit.
… cannot wedge the host Root cause of the Mac-host relay wedge from the 2026-08-26 itest timing batch: CmxIrohLibEndpoint.accept() completed the whole server-side QUIC handshake (Incoming.accept, ALPN read, handshake completion) inline in CmxIrohEndpointServer's single serial accept loop. A peer that initiated a connection and then stopped making handshake progress (killed sim app, dead relay path) suspended that loop for the driver's full handshake timeout while the retrying client refilled the accept queue with more already-abandoned attempts, so the host stayed broker-registered and relay-attached but never completed another admission until app restart. The endpoint's accept() now returns an un-handshaken CmxIrohIncomingConnection whose establish() runs inside the same per-connection admission task that owns the rest of that connection's lifetime, bounded by the existing admission deadline and the driver's own handshake timeout. Identity-scoped capacity checks move to post-handshake registration, where the identity is TLS-verified; the global pending-admission cap still bounds pre-handshake work. The accept loop's only job is draining the accept queue, and an accept queue that ends while its generation is current now routes through endpoint recovery instead of dying silently under a still-published binding.

Move each state=completed log next to the check it reports.
Lines 74 to 76 log three stages as completed after all three checks have already run. The other stages in this function keep a paired state=begin and state=completed shape. If verifyReversibleWorkspaceRename throws, no stage log is emitted, so the gate log gives no stage attribution for the failure.

📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value
Reuse one default for the dial-phase timeout.
Three initializers repeat .seconds(5). The endpoint-only initializer hardcodes the literal, so a future change to the default can diverge silently. Declare one internal constant and reference it in every initializer default.

public init(Then use dialPhaseTimeout: Duration = Self.defaultDialPhaseTimeout in both public and internal initializers, and dialPhaseTimeout = Self.defaultDialPhaseTimeout in the endpoint-only initializer.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win
Share the relay-profile admission policy between the two runtimes. Both runtimes now duplicate the same pre-install policy: a debug override replaces the requested profile, then the managed profile must be a subset of the verified fleet and the fleet count must be in 1 ... CmxIrohRelayPolicyVerifier.maximumRelayCount. The two copies can drift, and a rule applied to only one runtime is a silent policy gap. Extract one resolver that returns the effective profile or throws, and keep the runtime-specific state updates in each extension.

Gate and age-bound authoritativeDiscovery reuse
At CmxIrohRegistryContextProvider.swift:195-217, gate the fallback with CmxIrohTrustBrokerClientError.preservesVerifiedStateDuringRefresh(_:). The current catch also reuses the snapshot for HTTP 403, configuration, authentication, non-HTTP, and invalid-response failures, which must fail closed.
Store the snapshot’s verification time and enforce maximumVerifiedDiscoveryReuseAge before calling resolveContext. Otherwise, stale bindings can reach grant()’s cached pair-grant path after broker-side revocation.

Reuse the production scope derivation instead of duplicating it.
This helper copies the transcript string and SHA-256 derivation from CmxIrohBrokerCredentialRepository.scope(accountID:appInstanceID:) (Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohBrokerCredentialRepository.swift, Lines 236-241). If production changes the transcript, bindingRotationDeletesLegacySecureRecord seeds the legacy record under a stale account. The #expect(await secureStore.recordCount() == 0) assertion then still passes, because no record was ever written where the code deletes. The test would stop proving legacy-record cleanup.
Widen the production private static func scope to static func scope and call it through the existing @testable import CmuxIrohTransport.
As per coding guidelines: "Place test scaffolding in the test target and observe internal production state through @testable import, widening declarations from private to internal rather than adding production accessors."

Replace real-clock synchronization in this test.
The watchdog and hanging receive stream depend on elapsed wall-clock time. This can make the test slow or flaky under scheduler contention.
Inject a controllable clock into the dial-phase bound. Make TestHangingIrohReceiveStream suspend on a cancellation-aware continuation. Advance the clock after the receive begins.
As per coding guidelines, Packages/**/Tests test code must avoid real wall-clock dependencies and use injected virtual clocks for time-driven behavior.

Resume pending accept waiters when the endpoint closes.
accept() suspends on a CheckedContinuation stored in acceptWaiters. close() resumes only stallWaiters and finishes the health stream. It never resumes acceptWaiters. After server.stop() cancels the accept task and supervisor.deactivate() closes the endpoint, the stored continuation is never resumed. A leaked CheckedContinuation produces a runtime continuation-misuse diagnostic and leaves the suspended accept task alive for the rest of the test process.
The comparable double TestAcceptingIrohEndpoint in CmxIrohEndpointServerTests.swift (lines 499-524) resumes every waiter on close() and installs a cancellation handler. Apply the same shape here.

PostgreSQL ALTER TABLE ADD CHECK NOT VALID ACCESS EXCLUSIVE lock documentation and Drizzle ORM pg-core check NOT VALID support
💡 Result:
In PostgreSQL, adding a CHECK constraint typically requires an ACCESS EXCLUSIVE lock on the table, which blocks all concurrent access (including reads) [1][2]. However, by using the NOT VALID option, you can add a CHECK constraint without performing an immediate, blocking scan of the entire table [1][3]. When you execute ALTER TABLE... ADD CONSTRAINT... CHECK (...) NOT VALID, PostgreSQL still acquires a lock on the table, but the impact is significantly reduced because the database does not perform the heavy, long-running validation scan of existing rows [1][2]. The command can be committed almost immediately [1][4]. Validation of existing rows can be performed later using the ALTER TABLE... VALIDATE CONSTRAINT command [1][2]. This validation step requires only a SHARE UPDATE EXCLUSIVE lock, which permits concurrent reads and writes (INSERT, UPDATE, DELETE) while the table is being checked [1][3]. Regarding Drizzle ORM, there is currently no explicit, first-class support for adding a NOT VALID check constraint through the standard pg-core schema definition API [5][6]. The pg-core check utility is designed to define standard CHECK constraints [5][6]. To implement a NOT VALID constraint with Drizzle, you would typically need to: 1. Define the table and constraint as usual in your Drizzle schema (or exclude the constraint if you want to manage it purely manually). 2. Generate the migration using Drizzle Kit [7]. 3. Manually edit the generated SQL file before applying it, adding the NOT VALID clause to the ALTER TABLE or CREATE TABLE statement [1][7]. 4. Run the migration to apply the NOT VALID constraint, then execute a separate migration or manual command to perform the VALIDATE CONSTRAINT step [1][3]. Drizzle Kit handles standard CHECK constraint generation [7], but it does not natively expose the NOT VALID syntax in its current ORM schema API [5][6].

Add both CHECK constraints with NOT VALID, then validate them in a follow-up migration.
The columns are added as nullable immediately before these constraints, so existing rows satisfy both predicates. Without NOT VALID, PostgreSQL scans the table while holding ACCESS EXCLUSIVE; VALIDATE CONSTRAINT can run later with a less restrictive lock. Drizzle’s check() API does not expose NOT VALID, so keep the schema declarations and edit the generated SQL migration manually.

…with member docs Addresses local review file-organization and DocC policy findings on the new public type.
…n unowned tasks Local review P1: when admission was full, each rejected attempt minted a fire-and-forget task, so a remote flood could create unbounded tasks and retain every incoming attempt. Abandoning on the loop is deliberate backpressure: rejection work is bounded to one attempt at a time and the pending-admission cap keeps covering all in-flight work.
|
Triage note from the review-triage pass that produced #10865, recorded here so future reviewers stop re-flagging it: the "host serves under an unconfirmed cached policy / unconfirmed-policy admission" finding is a FALSE POSITIVE. Disproof: |
The package suite hung roughly half the time since the #10858/#10888 test infrastructure landed (observed as multi-hour swift test processes with zero runnable threads). Two independent races, both in tests: 1. EndpointServerManualClock.sleep() woke waitUntilSleeping() waiters BEFORE registering its own sleeper continuation, with a suspension point (withTaskCancellationHandler) between the two. A fire() that won that race found sleeper == nil, did nothing, and the deadline never fired. Fix: register the sleeper and drain the waiters in one synchronous actor slice inside the continuation body. 2. timedOutHandshakeKeepsItsSlotUntilTheAttemptResolves enqueued its final connection right after releaseStalledHandshakes(), but the admission slot frees only when the stalled attempt itself resolves, which runs behind that call. When the accept loop won the race it (correctly, per #10888 semantics) abandoned the attempt as over-capacity and the test awaited an admission that was thrown away. Fix: retry the final dial until the freed slot admits it, asserting every interim refusal is admission_abandoned. Verified: the stalled-handshake suite hung 5-6 of 8 filtered runs before, 0/20 after; the full 697-test suite is 18/18 green across both heads after the fix.

During the 2026-08-26 itest simulator timing batch (31 launches, relayOnly through the GCP test relay, branch feat-iroh-integration-test @ 8405058), the Mac host repeatedly became unreachable through the relay after a client session ended abnormally (sim killed mid-session, host logged
Transport idle timed out), and never recovered until the host app was restarted. It cost 15/26 warm launches their Mac session.The relay's own logs rule out relay attachment: across the cycle-5 wedge onset the host's relay TCP connection was attached at 11:48:42Z and stayed up unchanged until 11:58:52Z, yet launches at 11:53:27Z and 11:56:11Z never got a session while 11:49-11:52 launches connected in ~35s. The client logs show route discovery succeeding (host still broker-registered, 21 bindings) and one last QUIC leg connecting in 205 ms at 11:10:47Z before every subsequent handshake timed out. The host was discoverable, relay-attached, and not accepting.
Root cause:
CmxIrohLibEndpoint.accept()completed the entire server-side handshake (Incoming.accept, ALPN read, handshake completion) inline inCmxIrohEndpointServer's single serial accept loop. One peer that initiates a connection and then stops making handshake progress (killed app, dead relay path) suspends the loop for the driver's full handshake timeout, while the retrying client refills the accept queue with attempts it has already abandoned by the time the host reaches them. The loop never catches up; occasional 80-240s successes were dials that happened to hit a momentarily empty queue. This is the host-side sibling of the reconnect-wedge family (#9178 is the phone-side session-corpse variant; #8930 fixed broker-rejection recovery but not accept-path ownership).Mechanism
CmxIrohEndpoint.accept()now returns an un-handshakenCmxIrohIncomingConnection. Itsestablish()runs inside the same per-connection admission task that owns the rest of that connection's lifetime, bounded by the existing 15s admission deadline and the driver's own handshake timeout. The accept loop's only job is draining the accept queue. Identity-scoped capacity checks move to post-handshake registration, where the identity is TLS-verified; the global pending-admission cap (10) still bounds pre-handshake work, and all existing close-reason strings are preserved. An accept queue that ends while its generation is still current now routes through endpoint recovery with the existing bounded backoff instead of the loop dying silently under a still-published binding.Principled or hacky: principled; it fixes the ownership defect (a connection's handshake belongs to that connection's task, not to the shared accept loop) rather than adding a watchdog. Residual risk: Swift task cancellation may not unwind an in-flight FFI handshake future, so a timed-out establish can linger until the driver's own timeout resolves it; it holds only its own slot and is closed on resolution.
Tests
Two commits so CI proves the test catches the bug: commit 1 adds
CmxIrohEndpointServerStalledHandshakeTests(a peer stalled mid-handshake, healthy peer queued behind it must still be admitted) which fails on the old pipeline; commit 2 adds the fix. Full package suite: 618 tests / 69 suites pass.Base caveat
