# backends: audited 2026-08-14 (defect 50). NOTHING dispatches this op: no arm in folia-engine
# `dispatch_op`, no `registerOp`/OP_TABLE entry in packages/compute, no `_BUILTIN_OP_MAP`
# key in folia/compute.py, no backend manifest. Declared EMPTY on purpose — an absent
# block would be indistinguishable from one nobody ever wrote.
# packages/compute-wasm/src/sweep.rs:260 `generate_sweep` exists as a crate fn; nothing registers an op for it.
