-- [Windows builds moq-relay tests](/quest/m0/nightly/windows-relay-expect.md) - an unfulfilled lint expectation stops failing the Windows build
 - [OBS audio-candidate test](/quest/m0/nightly/obs-audio-candidate.md) - the failed audio candidate check passes under TSan and load, fixed at its reproduced cause
 - [Feature shapes per crate](/quest/m0/nightly/hls-poll-closed-gate.md) - moq-hls `Broadcaster::poll_closed` is gated on `server`, and the gate checks each crate's feature shapes in isolation
+- [moq-relay tests build without default features](/quest/m0/nightly/relay-tests-features.md) - the integration tests gate their websocket and unix-socket fields on the features that define them
+- [qmux builds clean for iOS](/quest/m0/nightly/qmux-ios-dead-code.md) - `TcpStats` is gated to the platforms that implement it, so the iOS simulator build has no dead code

+# [XS] qmux builds clean for iOS
+
+## Goal
+
+`rs/qmux` compiles for the iOS targets `just swift simulator` builds with no
+warnings: `socket.rs`'s `AsRawFd` import, `TcpStats::fd`, and
+`TcpStats::borrow` stop showing as dead code there.
+
+## Plan
+
+They sit in `mod unix` under `#[cfg(unix)]`, but only the Linux and macOS
+`sys` modules read them, so on iOS (unix, neither OS) they are unused. Gate
+`TcpStats` and what only it uses on `any(target_os = "linux", target_os =
+"macos")`, matching the platforms that implement it, rather than adding an
+allow. Its `cfg(unix)` callers follow the same gate and report no socket
+stats elsewhere, as they already do off unix: `qmux::tcp::adopt`
+(`rs/qmux/src/tcp.rs`), the `lib.rs` re-export, and moq-relay's
+`socket_stats` (`rs/moq-relay/src/web.rs`).
+
+Decided 2026-10-26 (maintainer): fix qmux only. Making the Platform
+`cargo check` steps and `just swift simulator` deny warnings is out of scope.
+
+Found in Nightly
+[40192013303](https://github.com/moq-dev/moq/actions/runs/40192013303)'s
+macOS platform job, which passes only because those steps do not deny
+warnings.
+
+Public API: `qmux::TcpStats` stops existing on iOS, where it never worked.

+# [XS] moq-relay tests build without default features
+
+## Goal
+
+`cargo clippy -p moq-relay --tests --no-default-features` passes with
+warnings denied. Its integration tests use `listen::Config.unix` and
+`connect::Config.websocket` only under the features that define them.
+
+## Plan
+
+Seven `E0609`s, in `rs/moq-relay/tests/integration/{smoke,auth_lifetime,cluster_unknown,public_rules,session_revalidate}.rs`.
+Gate each use (or the tests that need the transport) on its feature instead
+of turning the features on for every test build.
+
+No CI lane builds this shape today. Workspace unification enables moq-relay's
+defaults through moq-cli, and Nightly runs
+`cargo check -p moq-relay --no-default-features` without `--tests`. Decided
+2026-10-26 (maintainer): fix it here on its own; the per-crate lane in
+[Feature shapes per crate](/quest/m0/nightly/hls-poll-closed-gate.md) keeps it
+fixed once that lands.

+# [S] Stuck-window eviction test on macOS
+
+## Goal
+
+`quic::driver::tests::stuck_window_evicts_the_lower_priority`
+(`rs/moq-tokio/src/quic/driver/tests.rs`) passes reliably on macOS, fixed at
+its cause.
+
+## Plan
+
+It failed in Platform run
+[40232491446](https://github.com/moq-dev/moq/actions/runs/40232491446) (job
+121287165236): the evicted low-priority writer's `stopped()` returned `None`
+instead of `Some(0)`, then passed in the next two runs. The likely cause is a
+real-socket race: the low stream's write and FIN complete before
+STOP_SENDING arrives. Reproduce it first, then make the ordering
+deterministic per this epic's rules (hold the low stream open until the
+eviction is observed, or drive it without real-socket timing), never by
+loosening the assertion.
+
+The deleted macOS `receive_credit` quest mentioned this test, but
+[moq-dev/moq#6732](https://github.com/moq-dev/moq/pull/6732) fixed only
+`receive_credit`.
