 ## Required
 
 - [moq-net compiles in Fuzz and send-depth](/quest/m0/nightly/send-overflow.md) - the ietf publisher future stops overflowing the Send check
-- [The Python sdist builds](/quest/m0/nightly/py-sdist.md) - the sdist carries every workspace crate moq-ffi needs
 - [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
 - [moq-net builds without async](/quest/m0/nightly/net-async-free.md) - the no-default-features lane stops pulling `async` back in
 - [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

-# [XS] The Python sdist builds
-
-## Goal
-
-Nightly's Release Py FFI "Build sdist" job builds and installs the moq-ffi
-sdist.
-
-## Plan
-
-Nightly [40192013303](https://github.com/moq-dev/moq/actions/runs/40192013303)
-fails in maturin's `cargo metadata`: the sdist lacks
-`rs/moq-ice/Cargo.toml`, which `moq-tokio` depends on since moq-ice was split
-out. `pyproject.toml` lists the extra sdist paths by hand. Fix it so a new
-workspace dependency cannot drop out of the sdist again, and keep the sdist
-build in a lane that runs before release.
