 ## Required
 
 - [Nightly's macOS platform job passes](/quest/m0/nightly/macos.md) - `moq-audio`'s tests compile on macOS again and the websocket version test's timeout is fixed if it recurs
-- [Nightly's Windows platform job passes](/quest/m0/nightly/windows.md) - `moq-vaapi` is gated to Linux and Windows-only unused items are fixed, so `platform.yml`'s Windows job builds and tests cleanly

-# [S] Nightly's Windows platform job passes
-
-## Goal
-
-The `Windows` job of `platform.yml` passes on `main`, both as Nightly's
-`platform / Windows` and on `workflow_dispatch` runs and release PRs. Every
-Windows-only warning or Linux-only crate it trips on is fixed at its cause,
-not silenced for the job.
-
-## Plan
-
-Planned 2026-11-09 (maintainer, from
-[moq-dev/moq#8251](https://github.com/moq-dev/moq/pull/8251)'s follow-ups,
-/quest-unblock). Known causes:
-
-- `moq-vaapi` is not gated to Linux under `--all`, so the Windows build tries
-  to compile it.
-- `moq-relay`'s memory integration test leaves items unused on Windows,
-  which `build.warnings = deny` turns into errors.
-- The 2026-11-09 dispatch on `quest/m2/video-codec-receive`
-  ([run](https://github.com/moq-dev/moq/actions/runs/42635646987)) failed
-  `just rs test -p moq-video --no-default-features --features render` on a
-  `dead_code` warning at `rs/moq-video/src/encode/backend/mod.rs:84`. Check
-  whether `main` has it too.
-
-Reproduce each on a `workflow_dispatch` of `platform.yml` for this branch
-before and after the fix. Gate platform-specific crates and items with `cfg`
-where they are defined, so a later Windows-only warning shows up as one new
-error rather than a pile.
-
-Public API: none. Wire: none.
