Consumes the foreign-implementable AddressLookupService from iroh-ffi PR #11 in CmuxIrohTransport, behind a Debug-only flag (default OFF), per plans/iroh-custom-discovery-ffi.md migration step 2.

Base caveat: part of the ideal-shape series, based on feat-iroh-integration-test; until that lands on main this diff shows the whole stack. This PR owns the last two commits (red contract tests, then the resolve/publish implementation).

Fork-pin caveat: not mergeable to main yet. The pin is manaflow-ai/iroh-ffi exact 1.0.2-cmux.9-dev.1, a published prerelease built from PR #11's head (c8a3029) plus regenerated Swift bindings, through the fork's own release pipeline (release/v1.0.2-cmux.9-dev.1 branch, CI-built 5-slice xcframework, checksum baked by the release bot, attested, tag-promoted). Merge only after fork PR #11 lands and a real v1.0.2-cmux.9 tag exists, then bump the pin (Package.swift + 4 Package.resolved) in one commit. Merging into feat-iroh-integration-test is fine now: the prerelease asset is a normal GitHub release the fleet resolves like any other.

Consumption mechanics (teammates)

Nothing special: the dep is a normal SPM version pin; swift build/swift test in Packages/Shared/CmuxIrohTransport, tagged reloads, and fleet builds all fetch the prerelease xcframework by URL+checksum. To cut another dev prerelease from a fork branch: clone manaflow-ai/iroh-ffi, branch release/v<version> from the feature head, regenerate bindings (cargo build --locked --lib, then the uniffi-bindgen + sed + patch steps from make_swift.sh, commit IrohLib/Sources/IrohLib/IrohLib.swift), run python3 scripts/release/bump_version.py --swift-release <version> --swift-repository manaflow-ai/iroh-ffi, push, wait for release_swift.yml to bake the checksum, verify per RELEASING.md, tag that exact commit, and let release.yml promote the draft. Do not merge the release branch.

Swift side

CmxIrohRegistryAddressLookup: AddressLookupService:

  • resolve answers in order: in-memory record cache (zero network) → injected persisted-record source → at most ONE broker fetch riding the discovery snapshot (and its backpressure gate). The fetch is single-flight (concurrent resolves join it) and cools down on failure by the iroh: enforce the dial deadline at the transport boundary, gate last-good discovery reuse, clamp expired-policy grace #10865 taxonomy: preservesVerifiedStateDuringRefresh failures back off on .foregroundClient, trust failures fail closed on a 5-minute-floor schedule. All well-formed fetched records are cached per endpoint id.
  • Record policy (CmxIrohEndpointRecordPolicy): parse+signature verification via the fork's parseEndpointRecord (Rust re-verifies again in magicsock), freshness owned by Swift (1h window, 5m skew — matches maximumPrivateHintTTL), and the relay allowlist rule: a record naming ANY relay outside managed catalog / custom profile / debug override is dropped whole (the ed25519 signature covers the full packet, so partial stripping is impossible). Mirrors the untrusted_relay rule in web/services/relay/report.ts and the unmanagedRelayURL hint filter.
  • publish verifies the endpoint's own record, primes the resolve cache, and POSTs the blob to the new endpoint-record route.

Install is flag-gated: CMUX_IROH_ADDRESS_LOOKUP (env or defaults, Debug builds only). ON = EndpointOptions.addressLookup gets the lookup while hint dials stay untouched, so magicsock merges Source::AddressLookup next to Source::App (safe A/B). OFF = nil lookup, byte-identical bind options (pinned by test). Wired on the Mac host runtime (with an iroh-diag section: installed-since, last resolve outcome/source, last publish outcome, counters, via the #10814 lock-mirror pattern) and on the iOS client composition.

Web side

Publish = new route POST /api/devices/iroh/endpoint-record rather than a field on the registration payload: iroh fires publish on address changes independent of the registration cadence, and forcing a full challenge-signed re-register per address change would couple the lookup to registration state. Flagged as the deliberately smaller change. The route requires the binding-request proof (no legacy account-credential fallback), checks the record's leading 32-byte public key equals the caller binding's endpoint id, caps size (105–1200 bytes decoded, canonical base64), and stores it as an opaque blob (iroh_endpoint_bindings.endpoint_record + CHECK constraints). Deliberately no server-side ed25519 verification and no reader trust: readers verify the signature in Rust, so any cache/replica may serve records. Discovery (publicBinding) now returns endpoint_record; revocation wipes it with the same posture as path hints. No account-revision bump on record writes (resolve pulls on demand; hints already bump revision on registration refresh).

Honest limitations (A/B phase, flag OFF by default)

  • A publish that fails before registration completes retries on the next address change, not on registration completion.
  • iOS allowlist for resolved records is frozen per endpoint generation (like hint dials); the Mac host reads the live policy mirror.
  • CmxIrohBackpressuredClientBroker/HostBroker.publishEndpointRecord uses an as? runtime check on the wrapped broker so existing fakes stay untouched; a non-record broker fails typed.
  • Stored records are not retention-swept beyond revocation wipe (single bounded column per binding; client applies its own freshness window).

Tests

  • Red commit: 14 contract tests against a stubbed resolver (9 failing); green commit implements resolve/publish, full CmuxIrohTransport suite 659/659 green locally against the prerelease pin.
  • Coverage: cache-hit resolve with zero network, persisted-cache tier, single fetch then cache, transient vs trust failure classes + cooldown + re-arm, relay-allowlist drop + trailing-slash tolerance, stale-record rejection, wrong-endpoint rejection, publish upload/prime/reject/upload-failure, sign/parse round trip + tamper detection, flag default-off/opt-in/env-precedence, byte-identical options with flag off.
  • Web: bun run typecheck clean; iroh unit suites green (trust broker publish/mismatch/proof/malformed/revocation-wipe, route handler wiring); DB behavior lane on local postgres:16 covers store/guard/wipe plus the CHECK constraint (which also caught that Postgres caps regex repetition at 255 — the length bound lives outside the regex).

Dictionary:

  • xcframework: Apple's multi-platform binary bundle; the fork ships the Rust core as one, checksum-pinned in Package.swift.
  • prerelease tag: a semver tag with a suffix (-dev.1) marking a temporary dev artifact.
  • binding-request proof: three signed headers proving the caller holds the endpoint key of a registered binding.
  • backpressure gate: the per-operation serializer in front of trust-broker calls.
  • DB behavior lane: the CI job running repository tests against a real postgres:16 with migrations applied.

Summary by cubic

Consumes the foreign-implementable AddressLookupService from manaflow-ai/iroh-ffi PR #11 in CmuxIrohTransport, behind a Debug-only flag (default off), and removes the client-held relay token machinery — managed relays are now tokenless with admission decided by the server-side relay allow hook.

Address lookup

  • CmxIrohRegistryAddressLookup.resolve answers from the in-memory record cache (zero network), then the persisted-record source, then at most one single-flight broker fetch that cools down per the transient/trust failure taxonomy.
  • Records naming a relay outside the managed catalog or custom profile are dropped whole; freshness is a 1h window with 5m skew, and resolved hex IDs use a nibble table instead of per-byte formatting.
  • publish verifies the endpoint's own record, primes the resolve cache, and posts the blob to the new POST /api/devices/iroh/endpoint-record route; discovery now returns endpoint_record and revocation wipes it.
  • Flag OFF binds byte-identical endpoint options, and release builds compile the flag and lookup away.

Token removal and fork pin

  • Deletes the relay credential coordinator, token types, issueRelayToken broker calls, the /api/relay/token route, and the dormant n0-hosted relay minter.
  • Pins manaflow-ai/iroh-ffi to prerelease 1.0.2-cmux.9-dev.1; not mergeable to main until the fork PR lands and a real v1.0.2-cmux.9 tag exists, then bump the pin in Package.swift plus four Package.resolved files in one commit.
  • Bundles prior iroh fixes: bounded dial phases, per-connection server handshakes, admission capacity release on connection liveness, register-when-ready publication, paired-peer allowlist admission, and client cache-first activation.

Written for commit 9df8825. Summary will update on new commits.

…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.

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.
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.
The QUIC handshake already proves the phone's EndpointId. Until now every
session still fetched a backend pair-grant JWS and presented it in-band,
so the Mac re-verified pairing per connection. Pairing authorization is
now written down once: when a pair grant verifies for the FIRST time for
a phone endpoint, CmxIrohAdmissionController records the grant's exact
initiator and acceptor tuples (bounded by the grant's signed expiry) in
CmxIrohPairedPeerAllowlist, a keychain-backed store scoped to the active
account, app instance, and bundle namespace.

On later connections the phone opens its control stream with NO
admission credential (control header credential code 0). The controller
resolves the TLS-proven remoteId against the allowlist and routes the
pinned tuples through the SAME online-registry validation a live grant
gets: both bindings must appear in this Mac account's authenticated
broker discovery (snapshot <= 30s old whenever reachable; the existing
connectivity-only fallback and 30s lease monitor apply unchanged), so
allowlist admission never bypasses the account scoping the grant carried.

Eviction: local revoke removes matching entries; a definitive registry
refusal (device unpaired, binding replaced) evicts on re-validation; an
acceptor identity change invalidates entries at lookup; sign-out wipes
the store. A stranger's proven-but-unpaired key is refused before any
broker round, and an evicted key stays refused even with a stale cached
grant.

Phone side: after one fully admitted session the registry context
provider marks the Mac established (persisted via the offline policy
cache, so it survives relaunch) and builds later contexts credential-less
with zero pair-grant HTTP calls. A refused credential-less admission
falls back once, in the same dial, to a freshly fetched grant via
CmxConnectivityEngine.

Grant bootstrap remains the path for unpaired identities and the
revocation-aware fallback.
…t dials

A warm client (verified cached binding + verified offline route record)
must activate with zero blocking broker rounds, and a warm dial covered
by the offline record must be served from cache with the discovery
refresh running behind the dial. The immediate authenticated refresh
fails closed per the existing taxonomy (non-transient rejection tears
down and wipes cached policy), staleness evidence still bypasses every
cached source, and a background refresh that proves the cached target
vanished marks the peer stale.

These tests fail on the current head: activation blocks on the
overlapped discovery sync, and dials block on a live broker snapshot.
Split CmxIrohPairedPeerAllowlist.swift into one-major-type files with
Swift-DocC on every public symbol, move the scope digest to a file-scope
private helper, and lift the shared test authorizer into its own file.
No behavior change; 661 transport tests still pass.

Fixes cmux#10897 (Stack token refresh every ~78s) and cmux#10873

Consume manaflow-ai/iroh-ffi v1.0.2-cmux.9-dev.1 (fork PR #11's
foreign-implementable AddressLookupService plus regenerated Swift
bindings, published as a checksum-pinned prerelease xcframework) and pin
the intended cmux-side behavior with failing contract tests:

- CmxIrohRegistryAddressLookup resolve must answer record cache first
  (zero network), then persisted caches, then at most ONE bounded broker
  fetch, single-flight, cooling down by the codified transient taxonomy
  (CmxIrohTrustBrokerClientError.preservesVerifiedStateDuringRefresh).
- Records naming relays outside the managed catalog / custom profile /
  debug override allowlist are dropped whole (the signature covers the
  full packet), mirroring the trust rule in web/services/relay/report.ts.
- publish must verify the endpoint's own record, prime the resolve
  cache, and upload the blob to the trust broker.
- Flag OFF (CMUX_IROH_ADDRESS_LOOKUP, Debug-only, default off) binds
  with byte-identical endpoint options.

This commit ships the surrounding surface green (record policy + cache,
broker record fetch/publish transport, endpoint-record web route with
storage and discovery exposure, debug flag, factory plumbing, iroh-diag
section, mac + iOS install seams) with resolve/publish stubbed, so the
suite runs red on exactly the lookup behaviors the follow-up implements.
resolve: in-memory record cache first (zero network), injected
persisted-record source second, then at most one broker fetch through
the discovery snapshot. The fetch is single-flight (concurrent resolves
join the in-flight task) and cools down after failures on the
transient-taxonomy split: preservesVerifiedStateDuringRefresh failures
back off on the foreground-client schedule, trust failures fail closed
on a 5m-floor schedule. Every well-formed fetched record is cached by
its own endpoint id; only allowlist-clean, fresh (1h window, 5m skew),
requested-id records are answered. Rust re-verifies signature and id
before magicsock merges them as Source::AddressLookup.

publish: verifies the endpoint's own record through the same policy,
primes the resolve cache, and uploads the blob via the authenticated
endpoint-record route; outcomes land in the iroh-diag mirror.

Iroh transport and runtime

Layer / File(s) Summary
Transport contracts and connection lifecycle
Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/*
Managed relay profiles no longer contain client credentials. Incoming connections complete handshakes through establish(). Dial phases use bounded timeouts. Endpoint admission tracks handshake and connection lifetime separately.
Runtime relay policy and publication gating
Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIroh*Runtime*, Sources/Mobile/*IrohRuntime*
Relay credential coordination is removed. Cached policies can activate before broker reconciliation. Fresh managed relays remain withheld until registration and relay readiness.
Transport and runtime validation
Packages/Shared/CmuxIrohTransport/Tests/CmuxIrohTransportTests/*
Tests cover tokenless relay profiles, bounded admission, capacity release, stalled handshakes, cache-first activation, relay readiness, and updated broker APIs.

Relay services and persistence

Layer / File(s) Summary
Relay policy, endpoint records, and attach reports
web/services/iroh/*, web/services/relay/*, web/app/api/relay/*, web/db/*
Relay policy is fetched without an endpoint credential. Endpoint records are validated, stored, published, and served through discovery. Relay attach and detach reports update binding state under bounded body, concurrency, and database limits.
Web validation and persistence tests
web/tests/*
Tests cover endpoint-record authorization and cleanup, attach-report ordering and trust, route responses, bounded request handling, and removal of relay-token issuance.

Release-gate and application integration

Layer / File(s) Summary
Release-gate simplification
Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShellReleaseGateSupport/*, ios/cmuxPackage/Sources/CmuxIrohReleaseGateSupport/*, scripts/run-iroh-release-gate.sh
Relay rollover and expiry scenarios are removed. Reports use schema version 5. The gate runs the standard verification sequence without relay credential inputs.
Diagnostics and build wiring
Sources/Mobile/*Diag.swift, Sources/TerminalController.swift, cmux.xcodeproj/project.pbxproj, Resources/Info.plist, ios/Config/Info.plist
Relay and address-lookup diagnostics are added to the local iroh_diag output. Debug relay policy trust-key settings and new source files are registered.
Application termination and support updates
Sources/AppDelegate.swift, Sources/AppTerminationRequest.swift, Sources/ExtensionWorktreePrototype.swift, cmuxTests/*
Quit confirmation defers termination to a later main run-loop turn. Worktree initializer tests pass explicit nil values and return the awaited mutation result.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 9df88

This change adds endpoint-record discovery and publishing while altering admission and publication behavior; the current head still has a dependency pin that is explicitly not ready for main and unresolved failure paths that can preserve revoked access, leave hosts undiscoverable, or break Release trust configuration. Merge should wait for these issues and the required dependency/tag update.

Full details: Cmux Swift Actor Isolation

Explanation

No explicit actor-isolation failure is introduced. The PR-owned Swift package uses Swift 6 but has no MainActor-by-default setting, and the new value models and async broker protocol therefore do not become implicit MainActor declarations. The pinned foreign AddressLookupService is AnyObject, Sendable without @MainActor. CmxIrohRegistryAddressLookup uses actor-owned fetch state and an OSAllocatedUnfairLock for its documented thread-safe diagnostics state. The mobile diagnostic readers are explicitly nonisolated, while the write path remains on the existing @MainActor runtime. No new background access to a UI-bound store is present.

Full details: Cmux Swift Blocking Runtime

Explanation

PASS. In the PR-owned Swift range (the address-lookup commits), no new semaphore, blocking wait, sleep, delayed dispatch, timer, polling loop, or main-queue sync was added. The only manual locks are tiny diagnostic snapshots in CmxIrohRegistryAddressLookup and MobileHostIrohRuntime+AddressLookupDiag; the code documents the required synchronous, main-actor-free socket/foreign-lookup boundary. Fetch coordination itself uses FetchState actor state and async task values. Existing TerminalController semaphore code was not changed by the PR.

Full details: Cmux Browser Automation Off-Main

Explanation

PASS: The PR does not change browser socket automation routing. Against origin/main, the only rule-scoped change is the existing iroh_diag command in Sources/TerminalController.swift, which appends relay and address-lookup diagnostics. ControlCommandExecutionPolicy.swift is unchanged, and no changed diff line mentions a browser.* command, WebKit callback, screenshot, cookie store, or page hook. Existing browser commands remain classified in socketWorkerMethods with policy coverage.

Full details: Cmux Expensive Synchronous Load

Explanation

No failure condition is introduced. The full PR diff adds no RestorableAgentSessionIndex.load(), SharedLiveAgentIndex load call, agent hook/session store scan, transcript/trajectory/workstream log read, or broad synchronous file/JSON parse on an interactive path. Sources/TabManager.swift, which contains the existing cache-first close-history fallback, is unchanged. The new iroh_diag code reads small lock-protected diagnostic values and does not load agent history. The only new production JSONDecoder use is for the bounded paired-peer allowlist actor, not an agent-history file.

Full details: Cmux Cache Substitution Correctness

Explanation

PASS. The changed production code does not introduce a qualifying cache substitution in a persistence, history, undo, or snapshot path. The existing diagnostic archive snapshot path is unchanged from origin/main. New cached transport paths handle cold and stale state: CmxIrohRegistryAddressLookup.resolve falls through from cache to persisted records and then broker fetch, while CmxIrohEndpointRecordPolicy checks endpoint identity, signatures, signed age, and relay allowlists. Client and host cache-first paths require verified persisted bindings, revalidate identities and grants or attestations, and schedule authoritative refreshes. CmxAuthoritativeDiscoveryResolver accepts cached discovery only when revision and reset checks pass. Changed web discovery and record paths read transactional database state or apply explicit timestamp and event ordering; they do not replace fresh reads with cached state. The diagnostic and settings snapshots are transient UI or diagnostic consumers, which the rule allows.

Full details: Cmux No Hacky Sleeps

Explanation

No changed non-Swift runtime code violates the rule. The only newly added timers are bounded request/database deadlines: readBoundedBody cancels the reader and clears its timer, relayHookDbClient cancels the query and clears its timer, and the relay report route bounds application latency with tests. The existing Iroh invalidation timeout is unchanged. The changed shell scripts add no sleep, timer, or polling command. Focused tests cover stalled admission, slow bodies, and report application expiry.

Full details: Cmux Algorithmic Complexity

Explanation

The new address-lookup path can rescan the full account record set for each target miss. CmxIrohRegistryAddressLookup.resolve calls fetchState.fetchOnce at lines 283-286 and scans every fetched blob. Successful fetches reset nextFetchAllowedAt to .distantPast at lines 167-170, so no successful-fetch snapshot or negative-result index suppresses the next miss. The broker fetch itself scans all discovery bindings at CmxIrohTrustBrokerClient+EndpointRecords.swift:9-10. The in-memory cache is explicitly limited to 64 endpoint IDs at CmxIrohEndpointRecordCache.swift:21-29; for an account with about 1000 records, resolving targets outside the retained 64 can cause O(T·N) work and repeated full discovery, rather than one linear scan. The PR provides no benchmark or lower bound that makes this slower shape acceptable.

Resolution

Retain each successful fetched record in a snapshot or dictionary keyed by canonical endpoint ID, and track the fetched endpoint-ID set for misses. Reapply freshness and relay-allowlist policy when serving the snapshot, and invalidate or refresh the snapshot when discovery or relay-policy state changes. Alternatively, add a broker/data-store query that fetches the requested endpoint record directly. Do not rely on the 64-entry hot cache as the only index for accounts that can contain roughly 1000 records.

Full details: Cmux Swift Concurrency

Explanation

No explicit Swift concurrency modernization failure is introduced. The diff adds no background DispatchQueue, DispatchGroup, new Combine state, or completion-handler API. Production Task uses are lifecycle-managed: cached discovery is awaited and cancelled with its operation, endpoint close watchers are stored and cancelled with active connections, and host/context refresh tasks are stored, generation-fenced, and cancelled. The registry fetch task is stored as the single-flight inFlight task and awaited. Test-only tasks and continuations model controlled races, which the rule allows. RunLoop.main.perform is used for the required AppKit termination boundary.

Full details: Cmux Swift `@Concurrent`

Explanation

The diff adds non-actor async transport work without an explicit concurrent boundary. CmxIrohLibIncomingConnection.establish() performs the FFI handshake (Incoming.accept, ALPN, and connect) and abandon() calls FFI refuse(), but neither has @concurrent. The server invokes incoming.establish() from CmxIrohEndpointServer, which is an actor. The new CmxIrohRegistryAddressLookup.resolve(endpointId:) and publish(record:) also perform record parsing, cache work, and broker network operations without @concurrent; the lookup is installed as the foreign AddressLookupService, whose generated callback directly awaits these methods. The same target already marks FFI-backed async methods in CmxIrohLibConnection with @concurrent, and the old accept path kept the handshake inside the endpoint actor before this diff extracted it.

Resolution

Add @concurrent to CmxIrohLibIncomingConnection.establish(), CmxIrohLibIncomingConnection.abandon(), CmxIrohRegistryAddressLookup.resolve(endpointId:), and CmxIrohRegistryAddressLookup.publish(record:). Keep actor-isolated methods, such as FetchState methods and CmxIrohTrustBrokerClient methods, actor-isolated. Recheck the foreign callback and server paths to confirm that handshake, record parsing, and broker work do not inherit the caller actor.

Full details: Cmux Swift Package Boundaries

Explanation

PASS: The reusable lookup domain is implemented in the CmuxIrohTransport SwiftPM target. CmxIrohRegistryAddressLookup, CmxIrohEndpointRecordPolicy, and CmxIrohEndpointRecordCache own resolution, validation, caching, cooldown, and publishing, with focused package tests. The changed app-target code only constructs and injects the lookup, mirrors diagnostics, and appends app-specific iroh_diag output. These changes are app-lifecycle and composition glue, so they do not violate the package-boundary rule.

Full details: Cmux Swiftpm Lockfiles

Explanation

PASS. Packages/Shared/CmuxIrohTransport/Package.swift changes iroh-ffi from 1.0.2-cmux.7 to 1.0.2-cmux.9-dev.1, and the same diff includes the matching package-local Packages/Shared/CmuxIrohTransport/Package.resolved update to revision e74f6ec46c3bd037a4059aa43f67822f62615fc5. The root Xcode and iOS workspace lockfiles also contain the updated pin. The changed cmux.xcodeproj/project.pbxproj entries add source files and build settings; they do not change package references. No tracked package .gitignore contains a Package.resolved ignore rule. The deleted relay-minter .gitignore was for a non-SwiftPM Rust service and did not contain such a rule.

Full details: Cmux Swift Logging

Explanation

No logging-rule violation was introduced. The Swift diff adds no print, debugPrint, dump, or NSLog calls, and no file/stdout logging. Added runtime logs use the existing unified Logger or DiagnosticLog; the new error interpolation uses privacy: .private, and diagnostic events carry only classified values. The new iroh_diag sections are intentional socket report output, not ad hoc logging: relay URLs stay outside the privacy-safe export, and endpoint identifiers are shortened to a prefix. Existing file-scoped logger declarations were unchanged, so they do not create pull-request causality.

Full details: Cmux User-Facing Error Privacy

Explanation

The PR adds a user-visible CLI diagnostic output that exposes an environment variable name. Sources/Mobile/MobileHostIrohRuntime+AddressLookupDiag.swift formats Address lookup (\(CmxIrohDebugAddressLookupFlag.key)), and that key is CMUX_IROH_ADDRESS_LOOKUP. Sources/TerminalController.swift appends this report to the iroh_diag response. CLI/cmux.swift prints that response for cmux iroh-diag and lists the command in CLI help. The new report files are registered in the production Xcode Sources phase, and the address-lookup report is not DEBUG-gated, so the key can appear even when the lookup is disabled. When a relay override is active, the related report also prints CMUX_IROH_RELAY_URL_OVERRIDE. The rule explicitly forbids environment variable names in command output. The advanced-help exception does not apply because this is normal diagnostic output, not requested configuration help.

Resolution

Remove environment variable names from iroh_diag output. Use generic labels such as Address lookup and Source: debug override without printing CMUX_IROH_ADDRESS_LOOKUP or CMUX_IROH_RELAY_URL_OVERRIDE. Keep configuration keys only in developer-only documentation or explicit advanced configuration help.

Full details: Cmux Full Internationalization

Explanation

PASS. The PR changes no Swift string catalogs, InfoPlist localization catalogs, web locale files, or web/messages/* files. The new English literals are limited to local iroh_diag debug diagnostic output and diagnostic enum labels, not app UI or user-facing recovery text. The endpoint-record web responses use protocol fields and error codes such as published, invalid_endpoint_record, and binding_request_proof_required, which are literal API tokens rather than localized copy. No new locale-specific content requires translation updates.

Full details: Cmux Swiftui State Layout

Explanation

PASS — The diff introduces no prohibited SwiftUI state or layout pattern. The only changed SwiftUI view boundary, MobileIrohReleaseGateHostView, keeps its existing @State properties and only removes initializer arguments. MobileIrohReleaseGateScene only removes matching closure arguments. No added ObservableObject, @Published, @Observable, GeometryReader, lazy/list row store reference, or render-time state mutation appears in the changed lines. Existing SwiftUI markers in AppDelegate.swift and TerminalController.swift are unchanged and incidental.

Full details: Cmux Architecture Rethink

Explanation

The PR makes a diagnostic side channel a correctness source for relay-record validation. Sources/Mobile/MobileHostIrohRuntime+AddressLookupDiag.swift:37-41 reads currentRelayDiagState(), which returns the copied relayDiagMirror. Sources/Mobile/MobileHostIrohRuntime+Activation.swift:254-261 injects that read into every CmxIrohRegistryAddressLookup resolve. The authoritative policy remains in the lifecycle-owned relay policy service and host runtime, while relayPolicyEffective only copies state into the diagnostic mirror. The lookup is installed before the outer policy properties are assigned (Activation.swift:261 versus :496-498), so it can observe an empty or previous policy during activation. Later policy changes also update the owner and the mirror through separate paths. The lock provides synchronization for the copy, but it does not remove the duplicate authority. This materially expands the pre-existing diagnostic mirror into a functional allowlist side channel. It can reject valid records or evaluate records against stale policy state.

Resolution

Remove addressLookupAllowedRelayURLs() as a functional policy source. Keep the diagnostic mirror read-only for iroh_diag. Add one lifecycle-scoped, injectable relay-allowlist provider owned by the relay policy/host runtime pipeline. Construct it with the initial effective profile, pass it to CmxIrohRegistryAddressLookup, and update it in the same transition that applies replaceRelayPolicy, with the same lifecycle-generation fencing. Use that provider for both initial and subsequent lookup decisions, and add activation, policy-update, and account-switch tests that prove the lookup cannot observe an empty, stale, or cross-runtime allowlist.

Full details: Cmux Swift Auxiliary Window Close Shortcuts

Explanation

PASS. The Swift diff does not add or materially change a standalone cmux-owned window. The production additions are AppTerminationRequest and Iroh diagnostic/runtime code; the changed application logic schedules termination and appends diagnostic text, with no NSWindow, NSPanel, NSWindowController, Window, or WindowGroup creation. Window references in changed test code are test-only fixtures, which the rule allows. The existing shared owner list and cmuxWindowShouldOwnCloseShortcut routing remain unchanged.

Full details: Cmux Source Artifacts

Explanation

PASS — The changed paths contain hand-written source, tests, scripts, documentation, configuration, migrations, fixtures, and package metadata. The artifact-focused diff scan found no forbidden scratch/output directories and no binary additions. The removed relay-minter files and ignore files are intentional artifact removals. The pre-existing vendor/stack-auth-swift-sdk-prerelease contains source and tests; this diff does not add a dependency checkout.

Full details: Cmux No Test Or Debug Seam In Production Source

Explanation

PASS. The PR-side Swift diff adds no test-only accessor, ForTesting/ForTests member, test hook, or test seam. CmxIrohDebugAddressLookupFlag.swift contains a real Debug-only feature gate, and its production caller installs CmxIrohRegistryAddressLookup when enabled. The new diagnosticsSnapshot() is consumed by the production iroh_diag command through MobileHostIrohRuntime+AddressLookupDiag.swift, not only by tests. The diagnostic and flag code is isolated in dedicated feature/diagnostic files, so it matches the rule's allowed debug-facility cases. Existing unrelated DEBUG seams were not introduced by the PR-side changes.

Full details: Cmux No Ambient Global State

Explanation

The PR adds new ambient static namespaces and process-wide runtime state. CmxIrohDebugAddressLookupFlag.swift:12-49, CmxIrohDebugBrokerBypassHeader.swift:12-53, and CmxIrohDebugRelayOverride.swift:10-55 are caseless enums whose behavior is entirely static. CmxIrohEndpointRecordPolicy.swift:27-109 is also a static-only policy namespace. Sources/AppTerminationRequest.swift:19-31 is an empty enum with only a static scheduling method. In addition, Sources/Mobile/MobileHostIrohRuntime+AddressLookupDiag.swift:16-24 and Sources/Mobile/MobileHostIrohRuntime+RelayDiag.swift:54-88 add process-wide lock-backed mirrors accessed through static methods. These are new surfaces in the diff, not pre-existing code. The DEBUG-only guards do not provide an exception in this rule.

Resolution

Replace each debug/configuration enum with a constructable reader or configuration type that accepts the environment and UserDefaults dependencies, then inject it at the Mac and iOS composition seams. Replace CmxIrohEndpointRecordPolicy with an instance policy type configured with its relay allowlist and time dependencies; keep only allowed constants or private helpers static. Replace AppTerminationRequest with an injectable AppTerminationScheduler instance and pass it to the app quit handlers. Move the two diagnostic mirrors into a constructable, lock-backed diagnostics store owned by the host runtime and inject the same store into the socket-report path. Remove the corresponding static call sites and static mutable mirror state.

Warm client activation (verified cached broker binding + verified offline
route record) now resolves its start policy entirely from device-only caches:
zero blocking broker rounds, with the authenticated registration refresh
scheduled immediately behind activation (requiresDiscovery). The refresh
keeps the existing fail-closed taxonomy: a non-transient rejection or
authoritative discovery that drops the binding tears the runtime down and
wipes the cached policy, mirroring the Mac host's cache-first activation
(#10737). A broker floor (cooldown) no longer blocks a cache-first start;
a cache miss still rethrows it. #10857's invariant is untouched: a fresh
endpoint (no cached binding) still withholds managed relays until its
registration is acknowledged, and keeps today's blocking ordering.

Warm dials: CmxIrohRegistryContextProvider serves a dial from the verified
offline record (grants re-verified against the stored key set) when it
covers the exact tuple, arming one shared background discovery refresh
behind the dial. Staleness evidence (#10739/#10865) composes unchanged:
a marked-stale peer bypasses every cached source, and a background refresh
that proves the cached target vanished marks the peer stale so the next
dial rebuilds from fresh discovery. Rejections still never FALL BACK to
cache; the reworked provider tests pin that with an explicit staleness
mark so they exercise the fresh-discovery path.

relay-only (relayOnly transport verification mode) activation now restores
the verified cached policy for a warm client exactly like automatic mode
(F3 structural proposal), refreshing immediately after activation; a fresh
install, or the account whose previous cache-first relay-only activation
failed (dead cached fleet), keeps the blocking refresh.
challenge + register are two serialized POSTs whose only cryptographic
requirement is a fresh, one-use nonce in the signed transcript. A
self-contained proof (client nonce + signed unix-seconds timestamp,
transcript cmux/iroh/device-registration/v2) provides the same guarantees
the broker already accepts for every timestamp-signed binding request
(±5-minute freshness), plus server-side one-use nonce consumption.

Red across three suites: web unit tests (one-round register, replay
rejection, freshness window, tamper rejection, scoped projection), DB
behavior tests (atomic register + dedupe, challenge_superseded ordering
across mixed one-round and two-step flows), and the Swift broker client
(one HTTP round, old-server and skewed-clock fallbacks to the two-step
flow, authoritative rejections never retried).
…roof

Server: /api/devices/iroh/register accepts a body without challengeId
carrying issuedAt (unix seconds) and a client-chosen 32-byte nonce; the
Ed25519 signature covers cmux/iroh/device-registration/v2\n{issuedAt}\n
{nonce}\n{payloadSha256}. Freshness is the same ±5-minute window
verifyBindingRequestSignature already grants timestamp-signed binding
requests; one-use comes from registerWithSelfProof, which atomically mints
the challenge row already consumed (per-user select under the challenge
advisory lock, global nonce_hash unique index as backstop) and applies the
IDENTICAL slot registration via the extracted applyChallengeRegistration,
so adoption, reincarnation, revision advance, and the challenge_superseded
mint-time high-water gate cannot diverge between the flows. The dedupe row
outlives the proof's whole acceptance window. The two-step wire contract
is byte-for-byte unchanged for deployed clients.

Client: register(prepared:signer:) sends the one-round proof first and
falls back to the interactive challenge flow exactly when the two-step can
repair the rejection: an older broker's parse rejection of the proof shape
(400 invalid_challenge_id / unknown_field) or a client clock outside the
freshness window (403 self_proof_expired). Every other verdict propagates.
Randomness failure degrades to the two-step flow, whose entropy is the
server nonce.

Cold registration drops from 2 serialized broker rounds to 1.
… predicate

The iOS app compile caught relayOnlyRestoredPolicyIsUsable reading the
transport-internal activeRelays. Add hasDialableRelays as the public,
purpose-named accessor instead of widening the raw relay list.

Do not let .policyExpired mask a concrete resolution or cleanup failure.

When the graced policy is expired, lines 205-207 discard both cleanupFailure and resolution.failure. A fully stale managed selection then publishes zero relay routes but reports .policyExpired instead of .staleManagedSelection, and a credential-store failure reported as cleanupFailure disappears. CmxIrohRelayDiagnosticsSnapshot.failure reaches Settings as failureDescription, so the user-visible cause becomes wrong. Report the specific failure first and use .policyExpired only as the fallback.

Add publishEndpointRecord to the account-deletion fencing operations.

publishEndpointRecord calls assertIrohUserMutationAllowed in web/services/iroh/repository.ts (line 800), so it must fail with account_deletion_in_progress while a deletion is in flight. This operations array does not exercise it, so the new fence has no coverage.

1303-1331: 🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Sweep the leftover endpoint record in the revokedHints retention batch.

revokeActiveBindings nulls endpointRecord and endpointRecordUpdatedAt, so the normal revoke path is covered. The revokedHints batch exists to sweep revoked rows whose address-bearing fields were left behind, including rows revoked before this change. Those rows keep an endpoint record that names addresses, which contradicts the retention posture stated at lines 1182-1183.

Add endpoint_record to both the candidate predicate and the update. Add the same column to the revoked-row branch of irohRetentionBacklogExists (lines 1553-1555) so a row whose only leftover is relay_attached_url or endpoint_record is also reported as backlog.

🔒️ Proposed fix for the retention batch
           where revoked_at is not null
             and (
               path_hints_next_expiry is not null
               or direct_port_v4 is not null
               or direct_port_v6 is not null
               or relay_attached_url is not null

           set path_hints = '[]'::jsonb,

- Around line 1914-1939: The allowedRelayURLs closure in the
CmxIrohRegistryAddressLookup construction currently captures activation-time
endpointRelayProfile and managedRelayURLs. Update it to read the live relay
policy state maintained by CmxIrohLibEndpoint after replaceRelayPolicy(_:)
updates it, while preserving the debug relay override precedence and existing
fallback behavior.

In
`@ios/cmuxPackage/Tests/cmuxFeatureTests/MobileIrohRuntimeCompositionTests.swift`:
- Around line 1531-1534: Update the endpointFactoryProvider closure to pass its
second argument to MobileIrohEndpointFactoryModeRecorder.record, extend the
recorder to track whether addressLookup is present, and assert that the default
activation test records nil while preserving the existing bind-options equality
assertion.

In `@ios/Config/Info.plist`:
- Around line 139-143: Update the production configuration used by
ios/scripts/reload.sh --prod-auth so Info.plist receives exactly the current and
next production trust keys, excluding the extra keyID/publicKeyBase64 record.
Ensure the Debug-based production build applies a production-specific two-key
trust set consistent with IrohRelayPolicyProduction.xcconfig and the release
gate.

In `@Packages/Shared/CmuxIrohTransport/Package.swift`:
- Line 21: Update the dependency pin in the Swift package manifest from the
prerelease iroh-ffi version to the stable v1.0.2-cmux.9 tag once it is
available, and refresh the committed package-local Package.resolved entry to
match.

Apply the same fix in
`@Packages/Shared/CmuxIrohTransport/Sources/CmuxIrohTransport/CmxIrohLibEndpointFactory.swift`
around lines 3 - 24: The endpoint factory consumes APIs supplied only by the
prerelease dependency pin.

In

- Around line 154-171: Base withholdsManagedRelaysUntilRegistered on successful
verification of configuration.cachedBinding for the current launch, not merely
on cachedBinding being present; preserve the managed-relay and non-empty checks.
Ensure unverified cached bindings bind without managed relays so the

In `@Sources/AppTerminationRequest.swift`:
- Around line 23-30: Remove the RunLoop.main.perform deferral from schedule and
invoke the termination action directly through one main-actor-safe path. Update
the socket-command flow so its main-actor block completes before the lifecycle
owner requests termination, preserving a single termination entry point without

- Around line 37-42: Update CmxIrohRegistryAddressLookup construction and
resolution to capture the activation-policy snapshot from endpointRelayProfile

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Record the address-lookup argument so a test can prove the disabled default.

The composition claims that a disabled CmxIrohDebugAddressLookupFlag passes a nil lookup and keeps the bind options byte-identical. This fixture discards that argument, so no test observes it.

MobileIrohEndpointFactoryModeRecorder already exists. Capture the second argument there and assert it is nil in the default activation test.

♻️ Proposed change to record the lookup argument
-            endpointFactoryProvider: { mode, _ in
-                endpointFactoryModes.record(mode)
+            endpointFactoryProvider: { mode, addressLookup in
+                endpointFactoryModes.record(mode, addressLookup: addressLookup)
                 return endpointFactory
             },

Then extend the recorder in this file:

`@MainActor`
private final class MobileIrohEndpointFactoryModeRecorder {
    private(set) var modes: [CmxIrohTransportVerificationMode] = []
    private(set) var addressLookupPresence: [Bool] = []
    private(set) var bindingAuthorizationIDs: [String?] = []

    func record(
        _ mode: CmxIrohTransportVerificationMode,
        addressLookup: (any CmxIrohAddressLookupServing)? = nil
    ) {
        modes.append(mode)
        addressLookupPresence.append(addressLookup != nil)
    }
    // ...
}

Exclude the extra trust-key record from production artifacts.

ios/scripts/reload.sh --prod-auth builds with Debug and applies config/IrohRelayPolicyProduction.xcconfig; it does not use the Release configuration. The Debug settings therefore add the extra record to ios/Config/Info.plist. scripts/run-iroh-release-gate.sh requires exactly the current and next production keys, so the production artifact fails the gate. Generate a production-specific two-key trust set.

Do not merge to main while the Iroh dependency uses the prerelease pin. Package.swift and the package resolutions currently use 1.0.2-cmux.9-dev.1, which provides the new address-lookup API but is not the required stable v1.0.2-cmux.9 release. After that tag exists, update the manifest and all committed package-resolution files together.

Read the rate-limit rule id from the validated env module.

web/app/env.ts already declares CMUX_RELAY_TOKEN_RATE_LIMIT_ID (line 273) and trims it into runtimeEnv (line 370). The direct process.env read here skips that trimming, so a value with surrounding whitespace becomes a rule id that never matches and the firewall gate is silently ineffective. The report route in this cohort already uses env for its configuration.

Both migrations validate new CHECK constraints on the hot iroh_endpoint_bindings table. Four ADD CONSTRAINT ... CHECK statements omit NOT VALID, so each one takes ACCESS EXCLUSIVE on iroh_endpoint_bindings and scans the whole table while relay admission and discovery reads are blocked. Every existing row has NULL in the newly added columns, so NOT VALID plus a following VALIDATE CONSTRAINT gives the same guarantee under a SHARE UPDATE EXCLUSIVE lock.

Assert the record timestamp is also cleared on revoke.

cmxRegistrationRetriesAsTwoStep becomes a file-scope private helper per the
package-design policy, and CacheFirstRuntimeSeed moves to its own test
support file.
Review round 2 P1: the refresh armed behind a cache-first dial could
outlive the provider context (runtime teardown, policy identity
replacement) and later mutate the new context's staleness marks and LAN
authorities. cancelCacheFirstRefresh() bumps a generation fence and
cancels the task; runtime network teardown and updatePolicy's identity
replacement both invoke it, and the refresh re-checks the generation
after every suspension before touching provider state. Regression test
holds the refresh's broker call, cancels, releases, and proves the late
result cannot mark the peer stale.

- canonicalEndpointID now builds hex through a pure-Swift nibble table
  instead of per-byte String(format:), which the pinned review flagged
  as the known allocation hazard on concurrent hot paths (resolve runs
  it per dial and per fetched record).
- DocC on the new public diag outcome fields and the record-broker
  extension methods.
- The DB behavior test wraps the CHECK-violation update in a real
  Promise: a lazy postgres.js query object hangs under bun's
  expect().rejects, which awaits the thenable more than once; the hang
  wedged the whole DB lane after the failing await timed out.
The pairing-allowlist series made CmxIrohClientContext.credential optional
(credential-less admission for established peers); the cache-first tests
now unwrap it.

Pinned local review (gpt-5.6-sol, high, isolated): two rounds.

Round 1 verdict was "incorrect" on two findings; dispositions:

  • P0 String(format:) in canonicalEndpointID — fixed in 9b46aca: pure-Swift nibble table (resolve runs the conversion per dial and per fetched record, so the per-byte Foundation format path was a real allocation hazard).
  • P1 "relay readiness bypassed at CmxIrohClientRuntime.swift:526" — false positive and out of scope. This PR touches zero lines of that file (it is part of the feat-iroh-integration-test base this PR is stacked on, so the review bundle shows the whole stack), and the flagged hasConfiguredRelay() guard is immediately followed by try await connectivityEngine.waitForUsableHomeRelay() at line 530, so the claimed bypass does not exist.
  • P2 policy findings (57) — most target stack files outside this PR. On this PR's own files: missing DocC on the new public outcome fields and record-broker extension methods is fixed in 9b46aca; the OSAllocatedUnfairLock diag mirrors are intentional per the in-tree MobileHostIrohRuntime+RelayDiag / AgentChatThemeSync precedent (synchronous write visibility from non-async funnels, readable while the main thread is wedged), with the reasoning inline; CmxIrohDebugAddressLookupFlag mirrors the CmxIrohDebugRelayOverride namespace-enum shape deliberately; the test fixture/fake types beside their suite follow the existing suite convention.

Round 2 (post-fix head 9b46aca): the P0 is gone. One finding remains, again against stack code this PR does not touch: [P1] per-identity admission limits checked only after handshake completion (CmxIrohEndpointServer.swift:273, from the integration branch's accept-loop redesign commits e1ed22e / 4661bae / 616fc69). Out of scope here; flagged to the feat-iroh-integration-test owners as a possible pre-authentication pending-slot monopolization concern. Zero findings against this PR's own commits after round 1's fix.

Also assert endpoint_record_updated_at is null after revocation.

revokeActiveBindings nulls both endpointRecord and endpointRecordUpdatedAt. The endpoint_record_check constraint only forbids a record without a timestamp. A timestamp left behind with a null record therefore passes every constraint and this test. Select and assert both columns after revokeBinding.

Do not treat allowlist cleanup failures as success.

Lines 243-257 suppress secure-storage delete and write errors after updating loadedEntries. If a revoke or definitive registry denial removes an entry but storage fails, the old durable record survives. After restart, the allowlist can reload that record and admit the peer without a credential until the grant expires.

Propagate persistence failures and make the caller fail closed for cleanup operations.

Correct the admission documentation.

Line 43 says that admit() accepts a credential-bearing control stream. A control stream can now have no credential. Update the comment to describe credential or allowlist admission.

Remove the force try from the test helper.

try! converts an invalid relay profile fixture into a process trap. Make recoveredPolicy throw and propagate the error through the existing throwing tests.

Proposed fix
-        try await runtime.replaceRelayPolicy(
-            Self.recoveredPolicy(selectedRelayURL: recoveredRelayURL)
+        try await runtime.replaceRelayPolicy(
+            try Self.recoveredPolicy(selectedRelayURL: recoveredRelayURL)
         )
...
-        let recovered = Self.recoveredPolicy(selectedRelayURL: recoveredRelayURL)
+        let recovered = try Self.recoveredPolicy(selectedRelayURL: recoveredRelayURL)
...
-    ) -> CmxIrohEffectiveRelayPolicy {
+    ) throws -> CmxIrohEffectiveRelayPolicy {
...
-        let profile = try! CmxIrohEndpointRelayProfile(
+        let profile = try CmxIrohEndpointRelayProfile(
             managedRelayURLs: [selectedRelayURL]

Use completion signals or bounded predicate polling in cache-first refresh tests.

The fixed Task.yield() loops can finish before the refresh transition completes, making assertions depend on executor scheduling. Have the broker or refresh fixture signal the required completion, then await that signal with a deadline before asserting.

Also applies to the runtime refresh assertion in CmxIrohClientRuntimeCacheFirstTests.swift.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Remove the wall-clock assertion.

Line 52 reads Date() in an assertion. A debugger pause or CI stall can fail this test without a registration defect. Use a controlled clock with an exact expected timestamp, or keep this test to structural proof assertions.

As per coding guidelines: “Tests must not read wall-clock APIs such as Date() ... in assertions.”
