-# [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.
