iroh/auth hygiene: expiry-scheduled token refresh; visible + recoverable relay policy outage - #10909

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 A cached route identity is refreshed, never unpublished.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fixed in the next): - CmxIrohClientSession: an admission barrier that never answers must fail at the dial bound and be superseded by the next attempt (cmux#9724 16.2s dial, cmux#8531 silent redial hang).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

…ilds Debug-build-only override read from the environment (or the same-named UserDefaults key for iOS launch arguments). Applied at endpoint-profile resolution and at both runtime replaceRelayProfile funnels so a broker policy refresh cannot displace the test relay. Release builds compile the override away.

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.
…'s block Regression test for #10788. Routes the quit shortcut path's NSApp.terminate through one shared AppTerminationRequest seam (still synchronous here, so this commit stays red) and asserts the scheduled terminate does not run inside the requesting main-queue block.
…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.
… 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).
The cmux-staging Preview env signs /api/relay/policy with kid cmux-itest-relay-policy-2026-08 (dedicated integration-test key), but the Debug client trust root pinned only the two staging kids, so every policy fetch failed verification with an unknown kid (the 'Unknown failure' seen on the previous preview). Adds an optional third trust-key slot to the Info.plist array, populated only in the Debug configuration with the itest key. The trust-root parser now skips a slot whose two substitution variables are both empty (an unstaged slot expands to empty strings in Release), while any half-filled or invalid record still fails the whole trust root closed, pinned by tests.
…iews Vercel preview deployments of the broker sit behind deployment protection; the relay carries the bypass token in its configured allow/report URLs, but the app's trust-broker client had no way to pass it, so a tagged test build could not register, fetch policy, or discover against a protected preview at all. CmxIrohDebugBrokerBypassHeader (CMUX_IROH_BROKER_PROTECTION_BYPASS, env first then UserDefaults, DEBUG builds only, mirroring CmxIrohDebugRelayOverride) now rides every broker request as x-vercel-protection-bypass through the client's single request funnel. Release builds compile it away. Pinned by tests: header present when active, absent when inactive, unusable values rejected.
Three red tests for the P1s from the #10880 and #10858 reviews: 1. capacityFilledDuringAdmissionClosesTheUnplaceableConnection: capacity fills between registerEstablished and the admission marker; markAdmitted removes the pending entry, returns false, and orphans the established QUIC connection outside every capacity table. 2. timedOutHandshakeKeepsItsSlotUntilTheAttemptResolves: the admission deadline releases the slot while the consumed native handshake (not abortable by task cancellation) is still live, letting a remote peer mint more handshake work than maximumPendingAdmissions permits. 3. a not-ready refresh re-arms the ready gate: a refresh round that defers the first publication on relay readiness consumes the ready gate without re-arming it; with a stale binding no renewal deadline exists, so a relay that silently becomes usable again never publishes the binding.
… the ready gate Three ownership fixes for the reviews' P1s: 1. CmxIrohEndpointServer.markAdmitted: when capacity filled between registerEstablished and the admission marker and the identity has no predecessor to replace, close the connection (connection_capacity) before returning false. The pending entry is already removed at that point, so nothing else owns or closes the established connection. 2. CmxIrohEndpointServer.timeOutAdmission: a deadline that fires while the handshake is still in flight refuses the dialer but keeps the admission slot occupied (abandoned flag) until establish() resolves, because a consumed Incoming cannot be refused and the IrohLib bindings do not propagate task cancellation into the driver (uniffiRustCallAsync has no cancellation handler). registerEstablished/failEstablishment release the slot at resolution; the driver's handshake/idle timeout bounds it. Capacity is now honest: at most maximumPendingAdmissions native handshakes ever run. 3. CmxIrohHostRuntime: while the first publication is pending, a relay-readiness owner always exists. The not-ready refresh branch re-arms scheduleInitialPublication (it may have consumed the gate that scheduled it, readiness can return without a network-change event, and the renewal deadline is cadence-bound or nil for a stale binding), and the relay-required activation branch arms the gate alongside its retry loop.
Commit 1823b87 added the optional third trust-key slot only to the macOS target; the iOS target's Info.plist and Debug build settings did not carry it, so an iOS Debug build could not verify the preview's policy signed with kid cmux-itest-relay-policy-2026-08. Mirrors the macOS change: a third slot in CMUXIrohRelayPolicyTrustKeys expanded from CMUX_IROH_RELAY_POLICY_EXTRA_* variables, populated only in the iOS Debug configuration. Release leaves both variables undefined and the shared trust-root parser (already fixed and tested in 1823b87) skips the exactly-empty slot.
A live host refreshed its Stack access token every ~78s forever (cmux#10897): isTokenFreshEnough treats any token issued more than 75s ago as stale, so the first token request after 75s of token age forces a network refresh even though the token lives 3600s. PresenceHeartbeatClient requests tokens every 15s, producing the observed cadence. This commit only adds the deterministic tests (injected now) plus the non-behavioral clock plumbing, so CI shows them red before the fix.
…897) isTokenFreshEnough now treats a token as fresh while more than 300s remain before its exp claim (clamped to half the token's exp-iat lifetime, floored at 20s). The removed issued-age heuristic (issued <75s ago) forced a network refresh plus token-file rewrite every ~75s of token age forever: PresenceHeartbeatClient requests tokens every 15s, so a signed-in idle Mac refreshed every ~78s (189 writes/session observed) against a 3600s token TTL. Idle steady state now refreshes once per ~55min. Genuinely short-lived tokens refresh at half-life instead of on every request, and a revoked session is still caught by the 401 -> fetchNewAccessToken retry path, which never consulted freshness.
A host that activated during a relay policy outage installs the recovered policy via replaceRelayPolicy, which attaches the relay on the live endpoint but never republishes the registration: nothing owns a broker round after the relay set changes, so remote clients keep a direct-only route and the recovered host stays unreachable until some unrelated network change fires. Test only; the fix follows so CI shows red then green.
…ux#10873) replaceRelayProfile now schedules a forced registration refresh when the new profile's allowed relay URLs differ from the installed set. Relay attach alone never updated the broker: the recovered host kept serving its outage-era direct-only route to remote clients. Unchanged reinstalls schedule nothing, so periodic policy refresh successes do not add broker rounds. Turns the red recovery tests green.
CmxIrohRelayPolicyService now tracks the consecutive refresh failure streak (start time + count) and stamps it onto every published diagnostics snapshot; broker fetch failures, which previously published nothing, now republish diagnostics too. A success clears the streak. Visible state: the iroh_diag Active relay profile block reports 'Source: none — policy refresh failing since <t> (N consecutive failures)' when no policy is installed, and appends a 'Policy refresh: failing since' line when one is; the existing Iroh settings runtime status flips to .degraded once the streak reaches persistentRefreshFailureThreshold (3), so a host that cannot renew relay authority is no longer silently unreachable while LAN paths mask the outage.

credentials or that old credential timers close connections.

In
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohDebugBrokerBypassHeader.swift`:
- Around line 12-27: Update CmxIrohTrustBrokerClient.init to accept an optional
bypass value defaulting to CmxIrohDebugBrokerBypassHeader.activeValue(), store
it, and have performAuthenticatedRequest use the stored value instead of
resolving ambient state. In CmxIrohDebugRelayOverride.swift, pass the resolved
CmxIrohEndpointRelayProfile? from its constructable owner into the
endpoint-profile installation path rather than calling activeProfile() there;
apply these changes at both consolidated sites.

CmxIrohEndpointRelayProfile, rejecting malformed and non-HTTPS managed relay
URLs with the established configuration error. Extend CmxIrohConfigurationTests
alongside managedEndpointConfigurationIsTokenlessAndBoundedBySize to cover both
invalid URL cases while preserving the relay-count validation.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohDebugRelayOverrideTests.swift`:
- Around line 109-141: The existing
withoutOverrideUnavailableManagedSelectionBindsEmpty test does not cover
withholding managed relays until broker registration; update its doc comment to
describe only the relay-less binding behavior it verifies, and add a
behavior-level test using an active managed relay profile that asserts the
initial bind has no active relays and the managed profile is installed only
after registration acknowledgment. Anchor the new coverage to
HostRuntimeFixture, CmxIrohHostRuntime, TestIrohHostBroker, and
observedRelayProfileUpdates().
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohEndpointServerStalledHandshakeTests.swift`:
- Around line 56-66: Replace the sleep-based polling loop in the admission test
with a direct await of recorder.next(), then assert the returned admission has
healthyIdentity. Remove the admittedCount tracking and fixed-duration Task.sleep
calls while preserving the existing identity assertion.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohHostRuntimeRelayRecoveryTests.swift`:
- Around line 113-138: Make recoveredPolicy throwing and replace the force-try
construction of CmxIrohEndpointRelayProfile with propagated error handling;
update both recoveredPolicy call sites in the throwing tests to use try.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohHostRuntimeTestSupport.swift`:
- Around line 100-114: Update usableRelayHint() and the endpoint fixture that
consumes it to use an injected fixture-controlled timestamp or virtual clock
instead of Date(). Ensure the relay hint’s observedAt and expiresAt derive from
that controlled time, preserving the one-hour validity while allowing tests to
advance time deterministically.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/CmxIrohTrustBrokerClientTests.swift`:
- Around line 52-104: Isolate broker bypass tests from process-wide state by
using a dedicated UserDefaults suite and resetting it in test setup/teardown.
Update brokerRequestsCarryDebugProtectionBypassHeaderWhenActive and
brokerRequestsOmitProtectionBypassHeaderWhenInactive to inject that suite, while
supplying an explicit empty environment so process variables cannot override
expectations. Add resolution-order coverage through
CmxIrohDebugBrokerBypassHeader.rawValue(environment:defaults:), verifying
environment precedence and defaults fallback.
In
`@Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/TestDialingIrohEndpoint.swift`:
- Around line 53-57: Remove the extra blank line after the accept() method,
leaving exactly one blank line before healthEvents().
In `@Sources/AppTerminationRequest.swift`:
- Around line 19-25: Replace the static-only AppTerminationRequest namespace
with a constructable scheduler that stores the injected termination action, and
move the default NSApp.terminate behavior to the application composition
boundary rather than a production default parameter. Update callers to receive
and reuse one shared scheduler instance, preserving a single termination action
path while removing the production test seam.
In `@vendor/stack-auth-swift-sdk-prerelease/Sources/StackAuth/APIClient.swift`:
- Around line 90-105: Update isTokenFreshEnough to require the now parameter
without a production default, and update its production caller to pass Date()
explicitly. Preserve existing test callers’ ability to provide a fixed date and
leave the token freshness calculations unchanged.
In `@web/db/migrations/20260825120000_iroh_relay_attach_reports/migration.sql`:
- Around line 7-13: Update both CHECK constraints,
iroh_endpoint_bindings_relay_attached_url_check and
iroh_endpoint_bindings_relay_attach_reported_check, to be added with NOT VALID,
then add validation statements for each constraint so existing rows are checked
separately under the weaker validation lock.
In `@web/services/iroh/trustBroker.ts`:
- Around line 755-774: Update attachmentCorroborated so relayAttachedUrl is
accepted only when relayAttachReportedAt is present and within
SERVER_RELAY_ATTACH_LIVENESS_MS; do not use lastSeenAt as an alternative attach
timestamp. Keep lastSeenAt as a separate freshness validation gate wherever
attachment eligibility is evaluated.
In `@web/services/relay/hookDb.ts`:
- Around line 65-73: Update relayHookDbClient so bounds are included in cache
identity and compared on cache hits, including maxConnections, statement
timeout, and settle bound; update the corresponding cache.set entry to store the
bounds identity, ensuring calls with differing bounds create and retain distinct
clients rather than reusing an incompatible cached client.
- Around line 88-95: Update the pool acquisition flow around createAwsRdsIamPool
so waiting for an available client has its own finite checkout deadline, while
retaining connectionTimeoutMillis for connection establishment and the existing
statement/query timeouts. Also pin the pg dependency to the resolved 8.22.0
version rather than using the caret range.

| A signed-in native client calls `GET /api/relay/policy`. The web API returns the signed policy and the account preference; clients hold no relay credentials. Relay admission is server-side: the relay's allow hook (`POST /api/relay/allow`) checks the endpoint key proven in the iroh handshake and caches the answer. The app refreshes the signed policy before its expiry and replaces the verified relay policy on the live endpoint without changing EndpointID or application streams. |

Align the remaining relay-credential language with the tokenless model.
Line 118 now states that clients hold no relay credentials and that admission is server-side. Other passages in this same document still describe a client-held relay credential lifecycle, for example the "endpoint-bound credential contract", relays closing "each authenticated connection at its signed expiry", and the expiry-timer keying rule that prevents "an old credential's timer" from closing a refreshed connection. A reader cannot tell which statement is current.
Update those passages in the same change so the document describes one admission model.

In `@docs/iroh-app-transport-architecture.md` at line 118, The document’s
relay-credential lifecycle language conflicts with the tokenless, server-side
admission model described near the relay policy flow. Update the “endpoint-bound
credential contract,” relay expiry behavior, and expiry-timer keying passages so
they describe endpoint-key-based server admission and signed policy refresh,
removing assumptions that clients hold credentials or that old credential timers
close connections.

Avoid ambient process state for debug relay configuration.
CmxIrohDebugBrokerBypassHeader and CmxIrohDebugRelayOverride are static-only namespaces read at production consumption points, making behavior depend directly on environment or UserDefaults and causing tests to share process-wide state. Resolve these values at a constructable owner boundary and pass the resolved bypass value or relay profile into the client and profile-installation paths. Keep resolution-order coverage on injected environment and defaults.
This also aligns the relay override with the existing constructable diagnostics pattern and avoids adding ambient runtime state.

Track the rollout-gated deletion of this relay-readiness gate.
The note commits to deleting this gate and publishing at register time after the reporting relay build is deployed fleet-wide. The commitment has no tracking marker in the code or an issue reference, so it can outlive the rollout and keep the extra deferred-publication machinery permanently.
Do you want me to open an issue that references initialPublicationReady, scheduleInitialPublication, and the POST /api/relay/report rollout so this removal is tracked?

Add the CHECK constraints as NOT VALID, then validate them.
Both ADD CONSTRAINT ... CHECK statements run a full table scan while holding ACCESS EXCLUSIVE on iroh_endpoint_bindings. That lock blocks registration and discovery reads and writes for the duration of the scan. Both new columns are NULL for every existing row, so the scan proves nothing about existing data.

bounds is silently ignored on a cache hit.
The cache identity is hook plus configKey. bounds participates in neither. The first call for a hook name fixes the pool size, the statement timeout, and the settle bound for the lifetime of the runtime. A later call for the same hook with different bounds receives the earlier pool and no signal.
RelayHookDbBounds.maxConnections documents the invariant "pair it with the hook's concurrency cap so no hook operation ever queues inside the driver". That invariant depends on the bounds actually being applied. Make the drift impossible instead of relying on every call site passing identical bounds.

pg node-postgres Pool connectionTimeoutMillis query_timeout statement_timeout options documentation
💡 Result:
In node-postgres, the Pool and Client share configuration options, allowing you to manage timeouts and behavior through the configuration object [1][2][3]. Key timeout and configuration options: connectionTimeoutMillis: Specifies the number of milliseconds to wait for a connection to be established before returning an error [1][2]. It defaults to no timeout [2]. This is used when acquiring a new connection from the pool [4]. query_timeout: Defines the number of milliseconds to wait before a query call times out on the client side [2]. It defaults to no timeout [2]. This timeout is enforced by the node-postgres library itself [4][5]. statement_timeout: Specifies the number of milliseconds allowed for an SQL statement to execute on the PostgreSQL server [4]. It defaults to no timeout [2]. Because this is executed by the server, it can trigger errors if the statement takes longer than the allotted time [4]. Note that it can occasionally behave as a client-side error if the connection is lost or terminated during result processing [4]. options: A string containing command-line options to be sent to the server upon connection [2]. This can be used to set various PostgreSQL server-side configuration parameters, such as search_path, at the session level [2]. Other relevant settings: - idleTimeoutMillis: Determines how long an idle client remains in the pool before being closed [1][6]. - maxUses: Sets the maximum number of times a client can be used before it is disconnected and replaced [1][6]. - keepAlive: When set to true, enables TCP keepalive on the socket [2][5]. When configuring a Pool, these properties are passed to both the Pool constructor and the underlying Client constructor, ensuring comprehensive control over connection and query behavior [1][3].

Add a separate checkout deadline for the pg pool.
connectionTimeoutMillis limits new connection establishment, not waiting for an available pooled client. A saturated pool can therefore leave this operation waiting indefinitely. statement_timeout is applied to each client, and query_timeout bounds client-side query execution. Also, pg is resolved to 8.22.0; ^8.20.0 is not a pin.

Fixes #10897 and #10873.
Stacked-base caveat: this branch is based on
feat-iroh-integration-test, notmain, so the diff below includes that stack. Only the top 5 commits are this PR; it merges intofeat-iroh-integration-test, notmain.10897: token refresh every ~78s forever
Root cause is client-side, in the vendored Stack SDK (
vendor/stack-auth-swift-sdk-prerelease):isTokenFreshEnoughtreated any token issued more than 75s ago as stale, so the firstgetAccessToken()after 75s of token age forced a network refresh and a token-file rewrite even though the access token TTL is 3600s (verified by decoding live tokens fromcredentials.json; staging and dev Stack projects both issueexp - iat = 3600).PresenceHeartbeatClientrequests tokens every 15s, which turns that heuristic into a fixed ~78-80s refresh cadence (75s window + next 15s tick + network time), matching the 253auth: file.setTokenswrites in the reported log.Fix: freshness now schedules off the token's real expiry. A token is fresh while more than 300s remain before
exp, clamped to half the token'sexp - iatlifetime and floored at 20s. Idle steady state refreshes once per ~55min; a genuinely short-lived token refreshes at half-life instead of on every request. Revoked sessions are still caught by the existing 401-drivenfetchNewAccessTokenpath, which never consulted freshness. Deterministic tests injectnow.Red-green: commit 1 adds the tests plus non-behavioral clock plumbing (red locally: 4 failures under the old heuristic), commit 2 adds the fix (green). Note: CI's package-test lane does not run the vendored
StackAuthTestssuite (pre-existing gap; two of its legacy tests need a live local server), so the red leg for this half is proven locally, not in CI.10873: silently unreachable host after policy outage
Two halves, per the issue:
Recovery (tested red-green in CI-covered
CmuxIrohTransport):CmxIrohHostRuntime.replaceRelayProfileattached the recovered relay via the engine but never republished the registration: nothing owned a broker round after the relay set changed, so a host that activated relay-less kept serving its outage-era direct-only route and stayed unreachable for remote clients until some unrelated network change fired. It now schedules a forced registration refresh whenever the installed profile's allowed relay URLs actually change; unchanged reinstalls (every periodic refresh success re-applies the effective policy) schedule nothing. Commit 3 is the failing test, commit 4 the fix.Observability:

Fixes the auth token refresh cadence so idle hosts stop refreshing every ~78 seconds, and makes relay policy outages visible and recoverable instead of leaving hosts silently unreachable.
