+# [S] moq-mux live import tests on the paused clock
+
+## Goal
+
+The moq-mux live import restart tests (`live_import_restarts_forward_after_idle`
+for ts, fmp4, and flv) advance a paused clock across their idle gap and sleep
+no real time.
+
+## Plan
+
+Facts (`origin/main`, 2026-10-01): the helpers (`live_import` in
+`container/{ts,fmp4}/import_test.rs`, `import` in `flv/import_test.rs`) call
+`std::thread::sleep(idle)` with a 300 ms idle. The gap is measured through
+`clock::Anchor`, which reads `crate::Clock::now()`, and that is
+`std::time::Instant::elapsed()`, so a paused tokio clock can't move it.
+
+Decided (2026-10-01): `crate::Clock`'s monotonic epoch becomes a
+`web_async::time::Instant`. That is tokio's clock on native, so the tests start
+paused and call `tokio::time::advance`, and it takes `std::time::Instant` off the
+wasm path. #4687 used the same `Instant` type, but only for the private SI
+debounce after dropping its `crate::Clock`; `Clock` itself still reads
+`std::time::Instant`. The wall mapping stays `SystemTime`. Rejected: injecting a `now` into the importers through
+`translate_at`, which is plumbing only tests want.
+
+`std::time::Instant` is public at the boundary: `Clock::at(epoch, wall)` is
+re-exported from `moq-mux`, and the json and binary timed writes
+(`json.rs` `update`/`append`, and their `binary.rs` twins) take
+`Timed<_, Instant>` through the crate-private `Clock::stamp`/`capture`.
+`moq_net::Timed`'s docs say moq-mux uses `std::time::Instant`. Callers pass
+`std::time::Instant` from `test_util::late_clock`, moq-cli publish, moq-hls
+export, moq-audio and moq-video capture, and the catalog producer tests.
+
+Open (maintainer, ask before starting): keep the public inputs on
+`std::time::Instant` and convert at the boundary (native only; additive, stays
+on `main`), or switch them to `web_async::time::Instant` as a typed break on
+`dev` and update every caller and doc. Recommended: convert at the boundary,
+so only the private epoch moves.
+
+Public API: none if converted at the boundary; otherwise `Clock::at` and the
+timed writes change type. Wire: none.

+# [XS] Tracing captures survive the call-site cache
+
+## Goal
+
+No test in the workspace counts or asserts tracing events through a
+thread-scoped subscriber (`with_default`, `set_default`) that a parallel
+test can silence under a shared-process `cargo test`.
+
+## Plan
+
+#4690 found that tracing caches, per call site and for the whole process,
+whether any subscriber wants its events. With only scoped subscribers, the
+first thread to hit a call site decides for everyone, so a parallel test on a
+thread with no subscriber turns the event off and the capture misses it.
+Nextest runs each test in its own process and can't hit it, but `cargo test`
+does.
+
+Start after #4690 lands, with its open review finding on the subscriber
+installation window resolved, so the race isn't copied into other crates.
+
+Grep the Rust crates for tests that capture tracing output with scoped
+subscribers. Move each one onto #4690's pattern in
+`rs/moq-net/src/model/test_tracing.rs` (one process-wide subscriber, events
+routed to a per-thread capture). Its helper only counts WARN events by
+message, so a capture that asserts something else needs the helper
+generalized, or a shared copy if other crates need it. If none turn up, delete
+this quest.
+
+Public API: none. Wire: none.
