Summary

Plans the follow-ups the maintainer picked from this session's queued PRs:

• [S] If-let of a temporary whose rest drops, from moq-dev/rust2#654. if let Some(E::A(x)) = temp() emits a drop behind a second tag test that tsc rejects (TS2367). It's a safe-Rust bug.
• [M] u64 wrapping arithmetic in V8, from moq-dev/rust2#656. rs.u64WrappingAdd is about 7x a plain + in Node, which is most of parts/prefix-writes' remaining 12-13x.
• The wasm-bindgen closures quest's fixture keeps web-codecs' tokio channels, which translate since tokio's sync channels mapped into the runtime #654.

Decisions

Decided with the maintainer on 2026-11-07:

• ✅ Plan the if-let drop bug and u64 wrapping in m3. ✅ Fold the tokio channels into the closures quest's Plan rather than a new quest (rejected: keeping the Rc<RefCell<VecDeque>> stand-in).
• Dropped:
  • from moq-dev/rust2#644: self-referencing instances over a generic type's own parameters, and a bound on instances filled for Bin<S>-style doubling (no consumer or census hits either);
  • NonZero::from_mut (moq-dev/rust2#659);
  • Go case-only function clashes (moq-dev/rust2#658);
  • tokio's send_timeout and blocking_* (tokio's sync channels mapped into the runtime #654);
  • iter_mut through adaptors (perf(ts): step a slice's iter_mut by index, without a Place per item #656);
  • custom JS modules and experimental_generic_mono (moq-dev/rust2#657).
• Deferred until a consumer needs them: Nullable and wasm-bindgen schemas past 0.2.130 (Translate wasm-bindgen imports #657).
