ruview-advanced-sensing Advanced RuView capabilities — RuvSense multistatic sensing (attention-weighted fusion, geometric diversity, persistent field model), cross-viewpoint fusion across multiple nodes, RF tomography (ISTA L1 solver, voxel grids), longitudinal biomechanics drift, pre-movement intention signals, adversarial signal detection, and multistatic mesh security hardening. Use for research-grade or multi-node deployments. Bash Read Write Edit Glob Grep

RuView Advanced Sensing

The deep end: multistatic mesh, tomography, persistent field models, and the security model that protects them. Most of this lives in wifi-densepose-signal/src/ruvsense/ (14 modules) and wifi-densepose-ruvector/src/viewpoint/ (5 modules).

RuvSense multistatic mode (ADR-029)

Treat every WiFi link in range — including neighbours' APs — as a bistatic radar pair, then fuse them.

Module (signal/src/ruvsense/) Purpose
multiband.rs Multi-band CSI frame fusion, cross-channel coherence
phase_align.rs Iterative LO phase-offset estimation, circular mean
multistatic.rs Attention-weighted fusion, geometric diversity
coherence.rs / coherence_gate.rs Z-score coherence scoring; Accept / PredictOnly / Reject / Recalibrate gate decisions
pose_tracker.rs 17-keypoint Kalman tracker with AETHER re-ID embeddings
field_model.rs SVD room eigenstructure, perturbation extraction
tomography.rs RF tomography, ISTA L1 solver, voxel grid
longitudinal.rs Welford stats, biomechanics drift detection
intention.rs Pre-movement lead signals (200–500 ms ahead)
cross_room.rs Environment fingerprinting, transition graph
gesture.rs DTW template-matching gesture classifier
adversarial.rs Physically-impossible-signal detection, multi-link consistency

Cross-viewpoint fusion (ADR-016 viewpoint module)

Combine 2+ nodes geometrically — more nodes, more independent looks, tighter localization.

Module (ruvector/src/viewpoint/) Purpose
attention.rs CrossViewpointAttention, GeometricBias, softmax with G_bias
geometry.rs GeometricDiversityIndex, Cramér–Rao bounds, Fisher Information
coherence.rs Phase-phasor coherence, hysteresis gate
fusion.rs MultistaticArray aggregate root, domain events

Host-side helpers to explore the geometry before deploying: node scripts/mesh-graph-transformer.js, node scripts/passive-radar.js, node scripts/deep-scan.js.

Persistent field model (ADR-030)

field_model.rs builds an SVD eigenstructure of the room and stores it (RVF, ideally on a Cognitum Seed). New CSI frames are projected against it; the residual is the perturbation. Lets you ask "what's different from the empty-room baseline?" and survive restarts.

RF tomography

tomography.rs reconstructs a voxel occupancy grid from the multistatic link set via an ISTA L1 solver (sparse — most voxels are empty). Use with cross-viewpoint geometry for through-wall volumetric imaging. RuVector solver crates back the sparse interpolation (114→56 subcarriers).

Sensing-first RF mode & adaptive mesh kernel

  • ADR-031 (RuView sensing-first RF mode), ADR-081 (adaptive CSI mesh firmware kernel), ADR-083 (per-cluster π compute hop), ADR-095/096 (on-ESP32 temporal modeling with sparse GQA attention — runs the temporal head on-device).

Security (ADR-032 — multistatic mesh hardening)

Using neighbours' APs as illuminators and pooling links across a mesh expands the attack surface. Mitigations:

  • adversarial.rs rejects physically impossible signals and cross-checks multi-link consistency.
  • coherence_gate.rs quarantines low-coherence / suspicious links (Reject / Recalibrate).
  • Ed25519 witness chain (ADR-028) attests every measurement.
  • Run a security review when touching anything on the hardware/network boundary (see ruview-verify and docs/security-audit-wasm-edge-vendor.md).
