# `nvsim` is a standalone leaf crate. It deliberately has NO internal RuView
# dependencies — see `docs/research/quantum-sensing/15-nvsim-implementation-plan.md`
# §1.1 for the rationale. RuView integration (frame format alignment with
# `wifi-densepose-core::FrameKind`, ruvector trace compression, etc.) is
# tracked as Optional Integrations in a follow-up section of the README and
# lands behind feature flags after the core simulator is shipping.
