…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 A cached route identity is refreshed, never unpublished.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fixed in the next): - CmxIrohClientSession: an admission barrier that never answers must fail at the dial bound and be superseded by the next attempt (cmux#9724 16.2s dial, cmux#8531 silent redial hang).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.

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.
…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.

…on is acknowledged Cold-launch admission race (3/5 cold launches in the 20260826 sim timing batch): the endpoint binds with its managed relay map installed, native iroh dials the home relay immediately, and the relay's allow hook asks the broker about an endpoint whose registration is still in flight. The deny is negatively cached, the 15s relay gate times out, and the first activation lands 40-60s after launch. Red tests: a runtime with no cached binding must bind relay-less and install managed relays only after broker.register returns; a cached binding keeps relays installed at bind. The existing startInstallsExactIOSBindingAndManagedRelays invariant is updated to the new contract (one relay install, still tokenless).
…cknowledged A cached binding proves the broker has already seen this endpoint, so relay dials pass the relay's allow hook immediately and the profile stays installed at bind. Without one, CmxIrohClientRuntime now binds the endpoint with CmxIrohEndpointRelayProfile.unavailableManagedSelection and start() installs the real managed profile via the existing replaceRelayProfile machinery right after install(policy:), i.e. only once broker.register has been acknowledged (cooldown and offline fallbacks cannot reach that point on a fresh endpoint). The relayOnly usable-home-relay gate then waits on a dial that is guaranteed to be admissible, instead of one the relay may have negatively cached as denied. Custom relays are user-operated and not admission-gated by the cmux broker; they stay installed at bind so a broker outage cannot disable them.
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.

…iroh-integration-test
Three failing tests reproducing the pinned-review P1 findings: - dialBoundHoldsWhenTheStalledPhaseIgnoresCancellation: a dial-phase stall inside a non-cooperative driver call (the FFI bindings suspend on polled Rust futures that ignore Task.cancel()) must still fail at the configured dial bound instead of wedging the connect owner. - nonTransientRefreshFailuresDoNotReuseLastGoodDiscovery: rollback detection and non-transient broker rejections must fail closed toward re-discovery instead of dialing with the last-good snapshot. Keeps a companion test proving the cmux#9724 connectivity reuse survives. - expiredPolicyReuseGraceIsClampedToTheCacheMaximum: an unbounded caller grace must not make an expired signed relay policy reusable indefinitely.
…last-good reuse, clamped policy grace Three fixes for the pinned-review P1 findings on the iroh transport stack, each covered by the failing test in the previous commit. Dial deadline (CmxIrohClientSession): the dial-phase bound raced the operation against a timer inside a throwing task group, but the group still awaits the losing child on scope exit and cancelAll() is only cooperative. The admission barrier's stream I/O suspends inside FFI calls whose generated bindings poll Rust futures that Task.cancel() never resumes, so a stalled peer defeated the bound entirely and the connect owner wedged. boundedByDialPhase now takes an abortOnDeadline hook that terminates the operation at the transport boundary before failing typed; the admission phase passes a hook that closes the QUIC connection, which fails every pending stream call and ends the child. The endpoint dial phase needs no hook because CmxIrohLibEndpoint already bridges cancellation across the FFI boundary through the fork's cancellable ConnectAttempt. Last-good discovery reuse (CmxIrohRegistryContextProvider): the failed-refresh fallback dialed with the last verified snapshot for every error class, masking rollback detection, non-transient broker rejections, and invalid-authentication failures behind stale identity data. The reuse is now gated on the codified transient taxonomy (CmxIrohTrustBrokerClientError.preservesVerifiedStateDuringRefresh), so connectivity failures and broker cooldowns keep the cmux#9724 behavior while trust signals fail closed toward re-discovery. Expired-policy reuse grace (CmxIrohRelayPolicyCache): load() accepted any positive grace, including .infinity, making an expired signed relay policy reusable indefinitely. The cache now owns a hard 24-hour maximum and clamps every caller value; NaN degrades to strict expiry.
…s acknowledged Host-side twin of the client cold-launch admission race: a freshly installed Mac host binds its iroh endpoint with the managed relay map installed, native iroh dials the home relay immediately, and the relay's allow hook asks the broker about an endpoint whose registration is still in flight. The deny is negatively cached (cmux-relay#9: first deny 5s, escalating), delaying the host's own usable-home-relay publication gate. Red tests: a host with no verified cached policy must bind relay-less and install managed relays exactly once, only after broker.register returns; a verified cached policy keeps managed relays installed at bind with no post-registration swap, pinning the warm cache-first activation path. The existing startBindsExactRegisteredIdentity invariant is updated to the new contract, and HostRuntimeAcceptingEndpoint now records relay profile installs instead of rejecting them.
…wledged Host-side twin of the client fix: CmxIrohHostRuntime.start() now binds the endpoint with CmxIrohEndpointRelayProfile.unavailableManagedSelection when no cached policy cryptographically verifies for this endpoint, and installs the real managed profile through the shared CmxConnectivityEngine.replaceRelayProfile machinery only after the policy resolve returns, i.e. once broker.register has been acknowledged (a fresh host cannot leave resolveInitialPolicy any other way: the cachedPolicy(after:) fallback requires the same verified cached policy whose absence made the bind withhold). The usable-home-relay publication gate then waits on a dial the relay can admit. The withhold decision runs the full validateCachedPolicy check before bind, using the endpoint identity derived from the configured secret key, so a stale or rotated cache withholds instead of racing. A verified cached policy keeps the old behavior: relays installed at bind, warm cache-first activation unchanged. Custom relays are user-operated, not admission-gated by the cmux broker, and stay installed at bind so a broker outage cannot disable them.
… its own identity Deterministic regressions for #10874: after an abnormal client death (no clean close), a redial from the SAME TLS-authenticated identity is refused "connection_capacity" until the transport idle timeout releases the dead predecessor's slot (measured 2-9 min in the 20260826 sim timing batch). Three red tests capture the required behavior: same-identity redial admitted promptly at identity capacity, same-identity redial admitted when its own dead predecessor holds the last global slot, and a transport-reported close releasing the slot without waiting for the parked handler. A fourth (passing) test pins the anti-DoS guard: a different identity can never preempt an occupied slot.
…timer Fixes #10874. After an abnormal client death the dead connection kept its admission slot until the QUIC idle timeout, so the same identity's redial was refused "connection_capacity" or "connection_identity_capacity" for the 2-9 minutes the timer needed. Two mechanisms, both driven by state the server already owns: 1. Identity-scoped preemption. A TLS-authenticated peer may always run one replacement admission against its own connections: the replacement reservation in registerEstablished no longer requires a never-usable predecessor or a per-identity bound above 1, and markAdmitted admits one connection over the bound when the same identity's predecessors are all usable (a dead peer's session stays "usable" until the transport notices). The predecessor is retired only by markUsable, after the replacement proves itself end to end, so a live session is never torn down for an unproven redial. 2. Transport-signal release. Every active connection gets a close watcher on connection.waitUntilClosed() (the driver's own terminal signal: peer close, transport error, or its timeout). The slot is released and the handler cancelled the moment the signal fires, instead of when the parked handler unwinds. Anti-DoS bounds are preserved: the global pending cap and the one-pending-admission-per-identity cap are unchanged, a replacement reservation exists only while no other admission from that identity is pending, the transient overshoot is at most one connection per identity that already holds a slot, and an identity with no connection of its own can never preempt anyone (pinned by the new differentIdentityCannotPreemptAnotherIdentitysSlot test). fullServerRejectsReconnectCandidateWithoutDisruptingActiveConnection asserted the defect (same-identity reconnect refused at full capacity); it now asserts the replacement semantics and keeps its stranger-refusal half.

… feat-iroh-integration-test
… relay override A Mac host without a verifiable cached policy is configured with the relay-less .unavailableManagedSelection placeholder. start() reads currentEndpointRelayProfile (copied from the configuration in init) before the override-aware resolvedEndpointRelayProfile(), so the DEBUG-only CMUX_IROH_RELAY_URL_OVERRIDE is never consulted at bind and the endpoint binds with zero relays and never dials the test relay. This commit adds the failing test (red) plus the injectable start plumbing that faithfully preserves the bug, and a companion test that pins the no-override baseline: without the override the placeholder still binds empty, preserving the withhold-managed-relays-until- registered ordering from #10867.
start() now resolves the endpoint relay profile as debugRelayOverride ?? currentEndpointRelayProfile ?? resolved(managed), so the DEBUG-only CMUX_IROH_RELAY_URL_OVERRIDE wins over the stored .unavailableManagedSelection placeholder (and any other configured profile) at the bind itself, matching the two existing application points (nil-profile resolution and replaceRelayProfile) through the same CmxIrohDebugRelayOverride funnel, read once by the public start(). The override is a custom profile and custom relays are exempt from the withhold-managed-relays-until-registered ordering, so applying it here does not reintroduce the pre-registration relay admission race from #10867; the no-override placeholder path still binds with zero relays (pinned by test).

“Source: managed selection unavailable (relays disabled)” and “Relays: (none)”.
In `@docs/iroh-app-transport-architecture.md`:
- Line 118: Update the relay-fleet paragraph to remove endpoint-bound
credential, signed-expiry connection closure, and per-credential expiry-timer
language, aligning it with server-side admission through the relay allow hook
and signed policy refresh described near the relay policy flow.
- Line 175: Add live signed-policy expiry and refresh assertions to the
release-gate coverage exercised by MobileIrohReleaseGateRunner through
store.runIrohReleaseGateProbe(marker:), verifying that a live endpoint refreshes
before policy expiry rather than relying only on scheduling-helper unit tests.
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohClientRuntime`+RelayPolicy.swift:
- Around line 25-34: Extract the shared debug-override application and
managed-fleet validation into a helper such as
CmxIrohRelayProfileResolution.effectiveProfile. In
Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohClientRuntime+RelayPolicy.swift
lines 25-34, replace the inline logic with the helper and preserve the client’s
fleet-mismatch handling. In
Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohHostRuntime+RelayPolicy.swift
lines 25-34, call the same helper and map a nil result to
CmxIrohHostRuntimeError.relayFleetMismatch.
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohEndpointServer.swift`:
- Around line 443-448: Update markAdmitted so the refused replacement case where
requiresReplacement is true, replaced is nil, and activeForIdentity is empty
explicitly closes the authenticated connection before returning false, after
removing the pending admission. Preserve the existing admission and
active-connection cleanup behavior for all other paths.
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohHostRuntime`+PolicyRefresh.swift:
- Around line 631-650: In the initialPublicationPending branch of the policy
refresh flow, call scheduleInitialPublication(revision: revision) when
initialPublicationReady returns false, before scheduling registration renewal
and returning, so the deferred publication readiness gate is re-armed.
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohHostRuntimeConfiguration.swift`:
- Around line 78-84: Update both host and client relay resolver methods,
including resolvedEndpointRelayProfile, to require an explicit debugOverride
argument with no default value. Ensure CmxIrohClientRuntime.init and all other
call sites pass the resolved override explicitly, eliminating implicit reads of
CmxIrohDebugRelayOverride.activeProfile() from the resolver defaults and
relay-policy extensions.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohEndpointServerCapacityReleaseTests.swift`:
- Around line 112-124: Update the tests using firstReplacementOutcome so they
await the recorder’s completion signal after the outcome is received, then
assert the expected recorded count. Apply this to both count assertions in the
relevant test methods, preserving the existing outcome checks and expected
counts of 2 and 3.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohHostRuntimeTestSupport.swift`:
- Around line 100-126: Update usableRelayHint to accept an injectable observed
date, defaulting to the current date for existing callers, and derive expiresAt
from that same parameter. Update relayReadyEndpoint to expose and forward the
date parameter so tests can pin the hint clock alongside the runtime now value.
In `@Sources/AppTerminationRequest.swift`:
- Around line 23-31: Update AppTerminationRequest.schedule to invoke the
lifecycle-owned termination action directly instead of queuing it with
RunLoop.main.perform. Preserve the MainActor isolation required by the terminate
closure and ensure each entrypoint uses this single synchronous termination path
without adding deferred or reentrant run-loop behavior.
In `@Sources/Mobile/MobileHostIrohRuntime`+RelayDiag.swift:
- Around line 27-43: Replace the static locked mirror in
Sources/Mobile/MobileHostIrohRuntime+RelayDiag.swift:27-43 with the designated
non-main diagnostic owner that publishes the authoritative relay snapshot.
Remove the relayPolicyEffective didSet replication in
Sources/Mobile/MobileHostIrohRuntime.swift:111-115, and publish the snapshot at
the endpoint relay-profile lifecycle transition so diagnostics are updated
before hostRuntime.start() and remain aligned with the endpoint’s installed
policy.
In `@web/app/api/relay/report/route.ts`:
- Around line 60-70: In the report handler, validate the presence of the trimmed
RELAY_REPORT_SIGNATURE_HEADER before calling readBoundedBody, immediately
returning the existing 401 response when absent; retain
verifyRelayAllowSignature over body.bytes and the provided signature after the
body is read, and add a regression test covering a missing signature with a
never-resolving body stream.
In `@web/db/migrations/20260825120000_iroh_relay_attach_reports/migration.sql`:
- Around line 8-13: Add NOT VALID to both CHECK constraints,
iroh_endpoint_bindings_relay_attached_url_check and
iroh_endpoint_bindings_relay_attach_reported_check, so creation skips the
immediate table scan; leave validation for a later migration using VALIDATE
CONSTRAINT.
Apply the same fix in `@web/db/schema.ts` around lines 1011 - 1019: The schema
declaration reflects the same migration behavior and deployment-lock risk.
In `@web/services/relay/hookDb.ts`:
- Around line 88-111: Update the relay hook pool sizing around
createAwsRdsIamPool and the postgres configuration so per-hook
bounds.maxConnections respects the configured cloudDbConfig poolMax rather than
each hook independently using its concurrency cap. Track the combined relay-hook
and shared cloudDb pool ceiling across relay-allow and relay-report, and add
connection-saturation alerting using the existing pool monitoring path.
In `@web/tests/relay-report-route.test.ts`:
- Around line 275-289: Replace the real 25 ms timeout dependency in the timeout
tests around handleRelayReportRequest with an injected virtual timer or clock
shared by the body-read and apply-deadline helpers. Advance the virtual time
explicitly before asserting the 408 response, including the related tests around
the additional indicated range, while preserving their existing timeout
behavior.

Outside diff comments:
In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohHostRuntime.swift`:
- Around line 336-341: Update the requiresRelayReadiness startup path in
CmxIrohHostRuntime to pass the configured relayReadinessTimeout to
connectivityEngine.waitForUsableHomeRelay(), matching the timeout used by the
deferred wait while preserving the existing readiness and revision checks.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohTrustBrokerClientTests.swift`:
- Around line 287-305: Remove the unused relayJWT, makeRelayJWT, and base64URL
fixtures from the test target, while preserving relayURLs for the discovery
tests that still use it.

Add coverage for the managed-unavailable diag branch.
The four new tests cover .managed, .custom, and the nil-policy case. They do not cover .managedUnavailable, .customUnavailable, or the empty relayURLs case that prints Relays: (none). This PR changes exactly the .unavailableManagedSelection path, so a regression there would not be detected by this suite.

Remove the stale relay-credential wording that this paragraph now contradicts.
Line 118 states that clients hold no relay credentials. The relay-fleet paragraph a few lines below still describes an "endpoint-bound credential contract", relays closing "each authenticated connection at its signed expiry", and per-credential expiry timers. Both statements cannot be true after the tokenless change. Update that paragraph in the same PR so the document describes one relay-admission model.

Close the established connection when the replacement admission is refused.
Line 420 removes the pending admission before this check. If requiresReplacement is true, replaced is nil, and activeForIdentity is empty, markAdmitted returns false after the admission record is already gone. The connection is then tracked nowhere: finishHandler(id, ...) finds no pending admission and no active connection, so it returns without closing. The authenticated connection stays open until the transport's own idle timeout.
This state is reachable: registerEstablished admits the attempt while the identity still has an active connection, and that predecessor can close before markAdmitted runs, while other identities keep activeConnections.count >= maximumConnections.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Keep relay diagnostics under one authoritative non-main owner.
The static mirror duplicates relayPolicyEffective. During activation, the endpoint receives its relay profile before hostRuntime.start(), but the mirror updates only when relayPolicyEffective is assigned after startup. iroh_diag can therefore report no installed policy while the endpoint is already using one.

Reject a missing signature before reading the body.
At Line 60, an unauthenticated caller can provide a body stream that never completes and omit the signature header. The handler then holds the body reader until the five-second timeout before it reaches the missing-signature check. This allows unauthenticated requests to consume route capacity without performing HMAC verification.
Read and validate header presence before readBoundedBody. Keep byte-level signature verification after the body read. Add a regression test with no signature and a body stream that never resolves.

Track the total connection budget for the per-hook pools.
Each hook pool is sized from its own concurrency cap and ignores poolMax from cloudDbConfig (CMUX_DB_POOL_MAX, default 5). With relay-allow and relay-report both at 16, one runtime instance can hold 32 relay-hook connections in addition to the shared cloudDb pool. Under serverless fan-out this multiplies per instance. Confirm the database max_connections and any proxy limit accommodate the new ceiling, and add an alert on connection saturation so a relay burst cannot exhaust connections for the rest of the API.

Remove real-time timeout dependencies from these tests.
These tests depend on real 25 ms timers. Scheduler delay can make the tests nondeterministic. Inject a virtual timer or clock into the body-read and apply-deadline helpers, then advance it explicitly in the tests.
As per coding guidelines, “Test code must avoid real wall-clock dependencies: use injected virtual clocks and advance them manually for time-driven behavior.”

The DEBUG-only
CMUX_IROH_RELAY_URL_OVERRIDEis documented to force the relay for both host and client at every endpoint-profile installation. It was applied inresolvedEndpointRelayProfile()(nil-profile path) andreplaceRelayProfile(policy install), but NOT at host bind: when a Mac host has no verifiable cached policy, activation configuresCmxIrohHostRuntimeConfiguration.endpointRelayProfile = .unavailableManagedSelection,CmxIrohHostRuntime.initcopies it intocurrentEndpointRelayProfile, andstart()readscurrentEndpointRelayProfile ?? resolvedEndpointRelayProfile(). The override-aware resolver is never consulted, the endpoint binds with zero relays, and it never dials the test relay.Fix
start()reads the override once through the sharedCmxIrohDebugRelayOverridefunnel and resolves the bind profile asdebugRelayOverride ?? currentEndpointRelayProfile ?? resolved(managed), so the override wins over the stored placeholder (and any configured profile) at the bind itself, same as the other two application points.Interaction with #10867 (withhold managed relays until registration): the override is a
.customprofile and custom profiles are exempt from withholding, so this does not reintroduce the pre-registration relay admission race. The no-override placeholder path still binds with zero relays, pinned by test.The client runtime is unaffected: it always resolves through
resolvedEndpointRelayProfile()at init.Red-green
Commit 1 adds the failing test plus behavior-preserving injectable plumbing (fails on the assertion: bound profile is the empty managed placeholder, not the override), commit 2 applies the fix.
