#17 Stage 2 (TP hang-recovery) needs to call ncclCommAbort on a LIVE communicator from another thread — to unblock a collective wedged on a dead/hung peer so the ranks can resync. No cudarc release (incl. main) exposes this: the safe Comm only aborts in Drop, which can't fire while a stuck thread holds an Arc<Comm> clone. Pin neuron's cudarc 0.19.7 to a fork (grenade/cudarc @ nccl-comm-abort, rev 4dff0be) adding three thin methods — Comm::abort, get_async_error, and a raw comm() accessor — to be submitted upstream. The patch targets 0.19.x only; candle's transitive cudarc 0.17.8 stays on crates.io. Foundation only; the watchdog + abort + comm-rebuild that consume these land in follow-up commits (cuda-gated → validated by the blackwell build).
