Rvcsi
Description
rvCSI — edge RF sensing runtime: normalize WiFi CSI from Nexmon/ESP32/Intel/Atheros/file/replay into one validated CsiFrame schema, run reusable DSP, emit typed confidence-scored events, bridge to RuVector. Rust + @ruv/rvcsi (npm) + rvcsi CLI + a Claude Code plugin.

📡 rvCSI — edge RF sensing runtime
**Turn WiFi Channel State Information into validated, typed, confidence-scored RF events — in Rust, from TypeScript, from the CLI.**

rvCSI is the **stable, hardware-abstracted runtime layer** that real CSI pipelines are missing. Today, WiFi sensing is shell scripts, patched firmware, kernel modules, Python notebooks, PCAP dumps and ad-hoc DSP — formats differ per chip, drivers are unstable, malformed packets are common, device assumptions leak everywhere. rvCSI fixes that:
- Ingests CSI from many sources behind one trait (
CsiSource) — Nexmon (BCM43455c0 / Raspberry Pi 4 & 5, 4358, 4366c0), ESP32, Intel, Atheros,.rvcsicapture files, deterministic replay. - Validates every packet in Rust before it can touch application code — length/finiteness/profile checks, plausibility bounds, structured errors, never panics, never raw pointers across a language boundary.
- Normalizes everything into one schema —
CsiFrame→CsiWindow→CsiEvent. - Processes with reusable DSP — Hampel/MAD outlier filter, phase unwrap, smoothing, sliding variance, DC removal, baseline subtraction, motion energy, presence, heuristic breathing-band estimate.
- Emits typed events with confidence + evidence — presence started/ended, motion detected/settled, baseline drift, anomaly, signal-quality drop, calibration-required, breathing candidate.
- Bridges to RuVector as RF memory — deterministic win
