# RuView System Review — Capability Audit (Beyond-SOTA Series, Doc 00)
**Date:** 2026-06-09
**Scope:** The RuView product surface (ADR-031) and the 38-crate Rust workspace under `v2/crates/` that implements it, plus the ADR corpus (`docs/adr/`, 150 numbered ADRs) and the prior research corpus (`docs/research/sota-2026-05-22/`).
**Method:** Direct reads of `lib.rs`/`mod.rs` and key ADRs; static test counts via `grep -r '#[test]'` / `#[tokio::test]` per crate (counts are *static occurrences in source*, not CI pass counts). No metrics in this document are estimated — everything cited was read or measured in the working tree.
---
## 1. Executive Summary — What RuView IS Today
RuView is **not a crate**. Per ADR-136 §2.1 (`docs/adr/ADR-136-ruview-streaming-engine-frame-contracts.md`), RuView is the sensing-first *product surface and brand* (ADR-031, status: Proposed) layered on the existing `wifi-densepose-*` / `homecore*` / `cog-*` workspace. ADR-136 explicitly **rejects** a `ruview_*` crate rename and pins a normative ten-role mapping (ingest / signal / fusion / world / models / privacy / store / api / eval / observe) onto the existing crates.
What concretely exists:
1. **A deep, heavily-tested signal-processing layer.** `wifi-densepose-signal` contains 473 static `#[test]` occurrences, including a 22-file `ruvsense/` bounded context (`v2/crates/wifi-densepose-signal/src/ruvsense/`) implementing the ADR-029 six-stage multistatic pipeline plus ADR-030/032a/134/135/137/138/142/143 extensions (~14,000 lines, 330 in-module tests measured by per-file grep).
2. **A trust-traceable composition root.** `wifi-densepose-engine` (`src/lib.rs`, 752 lines, 11 tests) wires fusion quality (ADR-137), array coordination (ADR-138), evolution change-points (ADR-142), RF-SLAM anchors (ADR-143), the WorldGraph (ADR-139), and the BFLD privacy control plane (ADR-141) into one `StreamingEngine::process_cycle` (`lib.rs:285`) that emits a `TrustedOutput` (`lib.rs:80`) carrying evidence + model version + calibration version + privacy decision + a BLAKE3 witness (`lib.rs:437`).
3. **A privacy layer with structural invariants.** `wifi-densepose-bfld` (20 modules, 369 tests) implements ADR-118–123/141: raw BFI never exits the node (I1), identity embeddings are RAM-only (I2), cross-site identity correlation is cryptographically impossible (I3) — stated at `wifi-densepose-bfld/src/lib.rs:7-11`.
4. **A Home-Assistant-class world/state layer.** `homecore` + 9 sibling crates (state machine, event bus, plugins, automation, REST/WS API, recorder, HAP bridge, assist) — explicitly a "P1 scaffold" per `homecore/src/lib.rs:7` with deferred items listed at `lib.rs:24-31`.
5. **A drone-swarm extension.** `ruview-swarm` (17 modules, ~9,000 lines in subdirectories, 115 + 19 async tests), ADR-148 self-reports ~98% complete with the remaining 15% of M3 gated on real ESP32-S3 hardware (`ADR-148:940-953`).
6. **A large prior research corpus.** The 2026-05-22 autonomous SOTA loop: 41 ticks, 19 research threads (R1–R20), 22 numpy reference implementations, 7 ADRs, and a 6-tier production roadmap (`docs/research/sota-2026-05-22/00-summary.md`, `PRODUCTION-ROADMAP.md`).
The critical caveat, stated by the project itself: the ADR-136–146 series is *"a skeleton and nervous system, not a shipping product… Most of the series is not yet wired into the live 20 Hz pipeline"* (ADR-136 §8). The engine crate's own docs confirm what is absent: *"the live 20 Hz I/O loop (sensing-server), UWB hardware (ADR-144), and model training (ADR-146)"* (`wifi-densepose-engine/src/lib.rs:27-29`).
---
## 2. Capability Matrix — Pipeline Role → Crates → Maturity
Role mapping is normative per ADR-136 §2.1; maturity is this review's judgment from code + ADR status. Test counts: static `#[test]` + `#[tokio::test]` greps (2026-06-09).
| Role | Crate(s) | Key modules | Tests (sync+async) | Maturity | Evidence |
|---|---|---|---|---|---|
| **ingest** | `wifi-densepose-sensing-server`, `wifi-densepose-hardware`, `wifi-densepose-wifiscan` | `csi.rs`, `multistatic_bridge.rs`, `tracker_bridge.rs`, ESP32 TDM | 557+14, 137, 150 | **Production** (hardware-validated per ADR-028/039) | `sensing-server/src/` has 30+ modules incl. MQTT, Matter, RVF pipeline |
| **signal** | `wifi-densepose-signal` (incl. `ruvsense/`) | 6-stage pipeline (`ruvsense/mod.rs:9-23`), `cir.rs`, `calibration.rs`, `hampel.rs`, `fresnel.rs`, `phase_sanitizer.rs` | 473 | **Production** (unit level); live multistatic wiring **beta** | §3 below; ADR-014 Accepted, ADR-029 Proposed |
| **fusion** | `ruvsense/multistatic.rs`, `ruvsense/fusion_quality.rs`, `wifi-densepose-ruvector/src/viewpoint/` | `MultistaticFuser`, `QualityScore`, `CrossViewpointAttention`, GDI/Cramér-Rao (`viewpoint/geometry.rs`) | 20 (multistatic.rs), 3 (fusion_quality.rs), 136 (ruvector crate) | **Beta** — tested building blocks, composed only in `wifi-densepose-engine` tests | `viewpoint/mod.rs:1-30`; engine `lib.rs:317-319` |
| **world** | `homecore`, `wifi-densepose-worldgraph`, `wifi-densepose-geo`, `wifi-densepose-worldmodel` | `StateMachine`, `EventBus`, `WorldGraph` (rooms/sensors/person-tracks/semantic states), ENU geo registration | 9+11, 7, 16+1, 12+1 | **Beta** — homecore is explicit "P1 scaffold"; persistence/service dispatch deferred to P2 | `homecore/src/lib.rs:7, 24-31`; ADR-127 Proposed |
| **models** | `cog-pose-estimation`, `cog-person-count`, `wifi-densepose-nn`, `wifi-densepose-train`, `wifi-densepose-occworld-candle` | ONNX/Candle inference, training pipeline, OccWorld bridge | 7, 15, 30+1, 312, 12 | **Experimental** — no trained RF foundation encoder exists; ADR-147 benchmarked OccWorld with **random weights** | `ADR-147-benchmark-proof.md` ("random weights — pre-domain-fine-tuning baseline"); ADR-146/150 Proposed |
| **privacy** | `wifi-densepose-bfld` | `privacy_gate.rs`, `privacy_mode.rs` (mode registry + hash-chained attestation), `identity_risk.rs`, `signature_hasher.rs`, `embedding_ring.rs` | 369 | **Beta** — strongest-tested layer, but lib header still says "Status: P1 in progress" (`lib.rs:12`, stale vs 20 implemented modules) | ADR-118–123, 141 all Proposed |
| **store** | `homecore-recorder` | trajectory/event recording | 8+12 | **Experimental** | ADR-136 §2.1 |
| **api** | `homecore-api`, `homecore-server`, `cog-ha-matter`, `homecore-hap` | REST/WS, HA discovery, Matter, HomeKit | 7+11, 0, 63+1, 15+2 | **Experimental→Beta** (`homecore-server` has zero tests) | ADR-130/125/115 Proposed |
| **eval** | `wifi-densepose-train/src/ablation.rs`, `ruview-swarm/src/evals/` | ablation harness (ADR-145), swarm eval suite (ADR-149) | included in 312 / 115 | **Experimental** — ADR-145 self-labels "skeleton/scaffolding, mostly not yet on the live 20 Hz path" | `ablation.rs` exists; ADR-149 (swarm benchmarking) Accepted |
| **observe** | `homecore-automation`, `homecore-assist` | automation engine, assistant/Ruflo bridge | 20+14, 3+20 | **Experimental** | ADR-129/133 Proposed |
| **(integration root)** | `wifi-densepose-engine` | `StreamingEngine`, `TrustedOutput`, privacy demotion, witness | 11 | **Beta** — the only crate that proves cross-role composition; not on a live I/O path | `engine/src/lib.rs:1-29, 457-751` |
| **(swarm)** | `ruview-swarm` | Raft/gossip topology, RRT-APF planning, Candle PPO MARL, CSI sensing payload, failsafe, Ruflo | 115+19 | **Experimental/simulation** — M3 needs real ESP32-S3 hardware | ADR-148:940-953 ("Overall ~98%", M3 85%) |
| **(adjacent)** | `nvsim`, `nvsim-server`, `ruv-neural`, `wifi-densepose-wasm-edge`, `wifi-densepose-mat`, `wifi-densepose-vitals` | NV-diamond sim, neural lib, WASM edge, MAT disaster tool, vitals | 50, 0, 364, 643, 165+9, 52 | Mixed — `mat`/`vitals`/`wasm-edge` mature unit-wise | crate listing |
**Workspace totals (measured):** 3,890 `#[test]` + 121 `#[tokio::test]` static occurrences across `v2/crates/`. (CLAUDE.md's "1,031+ tests" figure refers to an earlier `cargo test --workspace` run count; this review did not execute the suite.)
External vendored runtimes also present: `vendor/rvcsi` (ADR-095/096 edge RF runtime, own repo), `vendor/ruvector`, `vendor/midstream`, `vendor/sublinear-time-solver`.
---
## 3. Signal-Processing Capability Inventory — `ruvsense/`
Location: `v2/crates/wifi-densepose-signal/src/ruvsense/`. CLAUDE.md says "16 modules"; the directory now contains **22 `.rs` files** (21 modules + `mod.rs`) — the table below is the ground truth. Lines/tests measured per file (2026-06-09).
| Module | Lines | Tests | ADR | What it does |
|---|---:|---:|---|---|
| `mod.rs` | 510 | 14 | 029 | Pipeline shell, COCO-17 keypoint constants, `RuvSensePipeline` (concrete fields + `tick()`), re-exports |
| `multiband.rs` | 442 | 14 | 029 | Channel-hopping CSI → wideband virtual snapshot per node (`MultiBandCsiFrame`) |
| `phase_align.rs` | 460 | 13 | 029 | LO phase-offset estimation via circular mean + `ruvector-solver::NeumannSolver` |
| `multistatic.rs` | 957 | 20 | 029 | Attention-weighted N-node fusion → `FusedSensingFrame`; timestamp-spread guards |
| `coherence.rs` | 474 | 19 | 029 | Per-subcarrier z-score coherence vs rolling template; `DriftProfile` |
| `coherence_gate.rs` | 380 | 17 | 029 | Accept / PredictOnly / Reject / Recalibrate gate decisions |
| `pose_tracker.rs` | 1,577 | 38 | 029/026/082 | 17-keypoint Kalman tracker, lifecycle state machine, AETHER re-ID embeddings, skeleton constraints, temporal keypoint attention |
| `field_model.rs` | 1,417 | 22 | 030 | SVD room eigenstructure (persistent field model), perturbation extraction |
| `tomography.rs` | 751 | 12 | 030 | RF tomography, ISTA L1 voxel solver |
| `longitudinal.rs` | 1,020 | 20 | 030 | Welford long-horizon stats, biomechanics drift detection |
| `intention.rs` | 511 | 12 | 030 | Pre-movement lead signals (200–500 ms) |
| `cross_room.rs` | 626 | 13 | 030 | Environment fingerprinting + room-transition graph |
| `gesture.rs` | 579 | 14 | 030 | DTW template-matching gesture classifier |
| `adversarial.rs` | 586 | 13 | 030/032 | Physically-impossible-signal detection, multi-link consistency |
| `attractor_drift.rs` | 566 | 15 | 032a | Midstream-enhanced attractor drift detection |
| `temporal_gesture.rs` | 540 | 15 | 032a | Midstream temporal gesture stream |
| `cir.rs` | 1,025 | 10 | 134 | CSI→CIR via ISTA L1 sparse recovery, NeumannSolver warm-start, `Complex32` sub-DFT Φ |
| `calibration.rs` | 717 | 8 | 135 | Empty-room baseline (Welford amplitude + von Mises phase), drift-triggered recalibration |
| `fusion_quality.rs` | 188 | 3 | 137 | `QualityScore` with `EvidenceRef`s, `ContradictionFlag`s, `CalibrationId`, privacy-demotion predicate |
| `array_coordinator.rs` | 343 | 5 | 138 | Clock-quality gating + `DirectionalEvidence` (geometric admission) |
| `evolution.rs` | 406 | 7 | 142 | Cross-link change-point detection, Bayesian `TemporalVoxelMap` (privacy-gated) |
| `rf_slam.rs` | 301 | 6 | 143 | Persistent reflector discovery → static anchor learning (Wall/Furniture/Mobile classes) |
Subtotal: ~14,400 lines, 310 tests inside `ruvsense/` alone. The non-ruvsense signal layer adds Hampel filtering, CSI-ratio, phase sanitisation, Fresnel modeling, BVP, spectrograms, subcarrier selection, and hardware normalisation (`signal/src/*.rs`).
**Cross-viewpoint fusion** (`wifi-densepose-ruvector/src/viewpoint/`, 5 files): scaled dot-product attention with geometric bias (`attention.rs`), Geometric Diversity Index + Cramér-Rao bounds (`geometry.rs`), phase-phasor coherence with hysteresis + clock-quality gate (`coherence.rs`), and the `MultistaticArray` aggregate root (`fusion.rs`). 136 tests crate-wide.
---
## 4. The Trust Chain — What Actually Composes Today
`wifi-densepose-engine/src/lib.rs` is the proof-of-composition. One `process_cycle` (`lib.rs:285-368`):
1. ADR-138 array coordination (only if every node's geometry is registered, `lib.rs:372-389`)
2. ADR-137 `fuse_scored_calibrated` with **per-node calibration epochs** — mismatching `CalibrationId`s raise a contradiction (`lib.rs:304-319`)
3. ADR-142 change-point → WorldGraph `Event` node (`lib.rs:393-430`)
4. ADR-141 monotonic privacy demotion on any contradiction (`demote_one`, `lib.rs:452-455`)
5. ADR-139/140 `SemanticState` with mandatory provenance (evidence ‖ model ‖ calibration ‖ privacy decision) (`lib.rs:336-352`)
6. BLAKE3 witness over the trust decision (`witness_of`, `lib.rs:437-448`)
The 11 engine tests verify exactly the right invariants: full provenance flow (`cycle_carries_full_provenance`, `lib.rs:487`), contradiction→demotion (`lib.rs:517`), determinism (`lib.rs:535`), calibration-mismatch→Restricted+stable-witness (`lib.rs:648`), privacy-mode attestation chain (`lib.rs:741`), and persist→reload round-trip with **no raw RF in the snapshot** (`live_frame_to_reload_same_contents`, `lib.rs:696-736`).
This is genuinely strong design. But all inputs are synthetic `MultiBandCsiFrame`s constructed in the test module; no ingest crate calls `StreamingEngine` yet.
---
## 5. Strengths
1. **Deterministic witness chain, end to end in design.** ADR-028 proof (`archive/v1/data/proof/verify.py` + SHA-256), ADR-119 BLAKE3 frame witnesses (`bfld/src/signature_hasher.rs`), ADR-136 `CanonicalFrame`/`ComplexSample` LE contracts, and the engine's per-cycle trust witness form a coherent auditability story few sensing systems attempt.
2. **Privacy as a control plane, not a feature.** BFLD's three structural invariants (`bfld/src/lib.rs:7-11`), hash-rotation (ADR-120), identity-risk scoring (ADR-121), mode registry with hash-chained attestations, and *monotonic* demotion wired to fusion contradictions (engine `lib.rs:327-328`) — uncertainty automatically reduces information release.
3. **Multistatic fusion with physics-grounded quality.** Attention fusion + GDI + Cramér-Rao bounds + clock-quality gating means geometry and synchronisation deficits are first-class, measurable contradiction sources rather than silent failure modes.
4. **Test density at the unit level.** 3,890 static test functions; the signal core (473), BFLD (369), and sensing-server (571) are the deepest. ruvsense files average ~14 tests/module.
5. **Honest self-assessment culture.** ADR-136 §8's "skeleton, not a shipping product" framing, ADR-147's explicit "random weights" disclosure, and homecore's in-source TODO-P2 ledger (`homecore/src/lib.rs:24-31`) make the gap analysis below mostly a matter of reading what the project already admits.
6. **A real prior research base with negative results.** The sota-2026-05-22 loop catalogued negatives by resolution path (missing-tool / architecture-error / physics-floor) and produced a ship-recipe (N=5 chest-centric placement, 100% coverage for 1–4 occupants) consolidated into ADR-113.
7. **Hardware path exists and was audited.** ADR-028 (Accepted) and ADR-039 (Accepted, hardware-validated) anchor the ESP32-S3/C6 ingest tier; firmware release process includes real-CSI verification on COM ports.
---
## 6. Honest Gap Analysis — ADR vs Implemented vs Integrated
| Capability | ADR status | Code status | Integrated on live path? |
|---|---|---|---|
| Six-stage ruvsense pipeline | ADR-029 **Proposed** | Implemented + tested (310 tests) | Partially — sensing-server has `multistatic_bridge.rs`/`tracker_bridge.rs`, but `RuvSensePipeline` still holds concrete fields with `tick()` only (`mod.rs`); no uniform `Stage<I,O>` chain runs live |
| Frame contracts (`ComplexSample`, provenance fields, `Stage` traits) | ADR-136 Proposed | Built + 9 acceptance tests (per ADR-136 §8, commit `11f89727f`) | **No** — AC6 600-frame replay witness key and AC7 cross-arch CI matrix not done; provenance fields not populated by live calibration/model stages |
| Fusion quality / contradictions | ADR-137 Proposed | `fusion_quality.rs` (188 lines, 3 tests) + engine wiring | Engine-tests only |
| WorldGraph digital twin | ADR-139 Proposed | `wifi-densepose-worldgraph` (4 files, 7 tests) | Engine-tests only; no recorder-backed persistence loop |
| Privacy control plane | ADR-141 Proposed | `privacy_mode.rs` registry + attestation chain, tested | Engine-tests only; MQTT/HA exposure exists in BFLD but the *engine→BFLD sink* live path is unwired |
| UWB range fusion | ADR-144 Proposed | **No hardware, no crate** — acknowledged absent (`engine/src/lib.rs:28`) | No |
| Ablation/leakage eval harness | ADR-145 Proposed | `wifi-densepose-train/src/ablation.rs` exists | Self-labelled "skeleton/scaffolding" (ADR-145 §status) |
| RF encoder multi-task heads | ADR-146 Proposed | Not trained; `model_id`/`model_version` registry unowned | No — engine stamps `rfenc-v1` as a placeholder string (`lib.rs:338`) |
| RF foundation encoder | ADR-150 **Proposed** | ADR only | No |
| World-model forecasting (OccWorld) | ADR-147 (benchmark doc) | Runs on RTX 5080, 72.39M params — **random weights**, no domain checkpoint | No |
| HomeCore HA port | ADR-125–133 all Proposed | P1 scaffold + siblings; `homecore-server` has **0 tests**; persistence, service mpsc dispatch, device registry, witness integration all deferred (`homecore/src/lib.rs:24-31`) | Partially (API surfaces exist) |
| BFLD capture path (Nexmon/ESP32 BFI) | ADR-123 Proposed | rvCSI vendored runtime exists for nexmon `.pcap`; BFI-specific capture unverified in this review | Unclear |
| Drone swarm | ADR-148 In Progress | 17 modules, sim + Candle PPO complete per milestones | **Simulation only** — M3's 15% requires physical ESP32-S3 CSI capture (ADR-148:946) |
| Federation / DP-SGD / PQC | ADR-105–109 Proposed | `ruview-fed` crate **does not exist** (roadmap Tier 2 item) | No |
| Antenna-placement CLI (`plan-antennas`) | ADR-113 Proposed; Roadmap Tier 1.1 HIGH | numpy references only; not found as a Rust CLI subcommand | No |
**Pattern:** the unit layer is real and deep; the *integration* layer is one crate (`wifi-densepose-engine`) exercised solely by its own synthetic tests; the *model* layer (anything learned: RF encoder, pose model fine-tuned on CSI, OccWorld domain weights) is the emptiest tier. Nearly every ADR ≥118 carries status **Proposed** even where substantial tested code exists — ADR status hygiene lags implementation in both directions (BFLD code outruns its "P1 in progress" header; ADR-148's "98%" outruns its hardware evidence).
---
## 7. Risk Register
| # | Risk | Likelihood | Impact | Evidence / Notes |
|---|---|---|---|---|
| R1 | **Integration gap**: trust chain proven only against synthetic in-test frames; live 20 Hz ingest→engine→BFLD-sink path unwired, so the headline guarantee (auditable provenance on every emission) is unverified in production conditions | High | Critical | `engine/src/lib.rs:27-29`; ADR-136 §8 |
| R2 | **No trained model**: every learned component (RF encoder ADR-146/150, OccWorld ADR-147) is random-weight or absent; sensing claims beyond coherence/occupancy heuristics cannot ship | High | Critical | ADR-147 "random weights"; ADR-146/150 Proposed |
| R3 | **Synthetic-validation bias**: ruvsense/engine/swarm tests and the sota-loop results (e.g., R3 "100% (synthetic)", ADR-113 placement numbers) are simulation-derived; real-room domain gap unquantified | High | High | `00-summary.md:45`; PRODUCTION-ROADMAP 2.3 ("turns synthetic numbers into validated numbers") |
| R4 | **Witness chain incomplete at frame level**: `CsiFrame.data` is still `serde(skip)` (ADR-136 Gap 2); AC6 replay-witness key and AC7 cross-architecture matrix not landed — deterministic replay is a design, not a property | Medium | High | ADR-136 §1.1, §8 |
| R5 | **Float nondeterminism in fusion** across thread counts could silently break the witness/replay contract once wired | Medium | High | ADR-136 §3.3 risk table (project's own assessment) |
| R6 | **Privacy bypass via unwired paths**: BFLD invariants are enforced per-module, but until the engine is the *only* route from ingest to API, a sensing-server endpoint can emit ungated state (sensing-server already has 30+ modules incl. pose/vitals APIs predating the control plane) | Medium | Critical | `sensing-server/src/` module list vs engine isolation |
| R7 | **Hardware dependence + scale**: multistatic TDMA/channel-hopping timing validated on small ESP32 sets; ADR-148 M3 explicitly blocked on real hardware; clock-quality model in engine uses a hardcoded `ClockQualityScore` (`engine/src/lib.rs:384`) | Medium | High | ADR-148:946; hardcoded 50 µs stdev |
| R8 | **ADR/doc/status drift**: 150 ADRs with near-universal "Proposed" status, stale in-source status headers (`bfld/src/lib.rs:12`), CLAUDE.md "16 ruvsense modules" vs 22 on disk, duplicate ADR numbers (two ADR-050s, two ADR-147s, two ADR-149s, ADR-052 ×2) — institutional-memory value degrades | High | Medium | `ls docs/adr/`; this review §3 |
| R9 | **Workspace breadth vs maintenance capacity**: 38 workspace crates + 4 vendored subtrees + Python archive + firmware; several crates have 0 tests (`homecore-server`, `nvsim-server`, `wifi-densepose-wasm`, `homecore-plugin-example`); bus factor appears to be ~1 | High | Medium | crate test-count table §2 |
| R10 | **Eval debt**: no end-to-end accuracy benchmark on real CSI with ground truth exists in-repo (ADR-145 harness is scaffolding; ADR-079 camera ground truth not exercised here) — "beyond SOTA" claims are currently unfalsifiable | High | High | ADR-145 status note; absence of ground-truth datasets in tree |
---
## 8. Measurement Appendix
- Test counts: `grep -r '#[test]'` / `#[tokio::test]` per crate directory, 2026-06-09. Workspace totals: 3,890 / 121. Top crates: `wasm-edge` 643, `sensing-server` 557+14, `signal` 473, `bfld` 369, `ruv-neural` 364, `train` 312, `mat` 165+9, `wifiscan` 150, `hardware` 137, `ruvector` 136, `ruview-swarm` 115+19.
- ruvsense per-file lines/tests: `wc -l` + per-file `grep -c '#[test]'` (table in §3).
- Crate inventory: `ls v2/crates/` → 38 directories.
- ADR inventory: `ls docs/adr/` → 150 numbered files (with the duplicate numbers noted in R8); `docs/adr/README.md` self-reports "45 ADRs" (stale).
- Caveats: static `#[test]` counts include `#[cfg(feature = ...)]`-gated and ignored tests; they are an upper bound on what `cargo test --workspace --no-default-features` runs. No cargo build/test was executed for this review.
*Next in series: 01+ documents should target the R1/R2/R10 axis — wiring the live path, training the RF encoder, and standing up a falsifiable real-CSI benchmark — before any "beyond SOTA" claim is made.*

Every claim in this document carries one of three tags. **No RuView benchmark number in this document is invented**; all RuView numbers come from repo-internal measured artifacts.
| Tag | Meaning |
|-----|---------|
| **[V]** | Verified in this session via web search (June 2026); source linked in §8 |
| **[K]** | Training-knowledge claim (pre-2026 literature); plausible but **not re-verified** — treat as needing citation check before external publication |
| **[I]** | Internal RuView measurement or artifact (ADR, issue, witness bundle) — measured, not literature |

### 1.1 Pose estimation (WiFi CSI)
| Method | Year | Metric | Dataset / protocol | Tag |
|--------|------|--------|--------------------|-----|
| DensePose From WiFi (Geng, Huang, De la Torre) | 2023 | Dense-pose UV regions from CSI, "comparable to image-based approaches" (same-layout); commonly cited AP≈43.5 / AP@50≈87.2 | 3×3 antenna, single-layout lab | exact AP numbers **[K]**; paper existence **[V]** (arXiv 2301.00250) |
| MetaFi++ (Zhou et al.) | 2023 | PCK@50 = **97.30%** same-domain real-world (MetaFi: 95.23%); drops to **81.7–86.5%** under stricter protocols | Own capture; protocol-sensitive | **[V]** |
| Person-in-WiFi 3D (CVPR 2024) | 2024 | End-to-end multi-person 3D; 20.4 M params, **54 FPS**; MPJPE ≈ 90–100 mm on own dataset | Own multi-person dataset | FPS/params **[V]**; MPJPE range **[K]** |
| GraphPose-Fi (arXiv 2511.19105) | 2025 | SOTA on MM-Fi random split: **MPJPE 160.6 mm**, best PCK at all thresholds | MM-Fi, random split (S1) | **[V]** |
| CSDS (Electronics 14(4):756) | 2025 | Wi-Pose: PCK@5 = **0.6407**, PCK@50 = **0.8824** | Wi-Pose | **[V]** |
| PerceptAlign (arXiv 2601.12252) | 2026 | Cross-layout 3D: MPJPE **222.4 mm** (Scene 4) / **317.1 mm** (Scene 5), >54% better than prior cross-layout SOTA; in easier settings MPJPE 181.5 mm, PCK@20/50 = 44.2/79.5 | Cross-layout protocol | **[V]** |
| WiFlow (arXiv 2602.08661) | 2026 | Lightweight continuous HPE, spatio-temporal decoupling | — | **[V]** (existence; numbers not extracted) |
| **RuView / AetherArena** | 2026 | **81.63% torso-PCK@20 in-domain (random split), beating MultiFormer's 72.25%** on metric/protocol-matched MM-Fi; **leakage-free cross-subject collapses to ~11.6% torso-PCK zero-shot**; official-split harness baseline ~63–65% PCK@20; **11 KB LoRA few-shot calibration → 72.5%** | MM-Fi (issue #876, ADR-150 §3) | **[I]** |
**The honest reading of the pose axis**: same-domain WiFi pose is "solved-looking" (PCK@50 in the 90s) and meaningless for deployment. The 2025–2026 literature has shifted to cross-layout/cross-subject protocols, where numbers collapse (PerceptAlign PCK@20 = 44.2 cross-layout **[V]**; RuView cross-subject zero-shot 11.6% **[I]**). ADR-150's measured finding — that the cross-subject gap is **subject-distribution shift, not an algorithmic gap**, and that **few-shot in-room calibration (5–200 frames) closes it** — is ahead of where the published literature is: no published WiFi-pose paper we found ships a per-room ~11 KB adapter calibration mechanism. **[I]**
### 1.2 Presence / person count
| Method | Year | Metric | Tag |
|--------|------|--------|-----|
| Large-scale commodity router deployment (>10 M routers) | 2025 | **92.6% motion-detection accuracy** across diverse homes | **[V]** (ISAC survey, arXiv 2510.14358) |
| LeakyBeam (NDSS 2025) | 2025 | Occupancy through walls at 20 m from **plaintext BFI alone**: TPR 82.7%, TNR 96.7% | **[V]** (also in BFLD survey §4.2) |
| Time-Selective RNN multi-room presence (arXiv 2304.13107) | 2023 | Device-free multi-room presence from CSI | **[V]** (existence) |
| Academic person counting (0–5 occupants, lab) | 2020–2024 | typically 90–97% exact-count accuracy, degrading sharply >5 people | **[K]** |
| **RuView** | 2026 | `cog-person-count` ships with calibrated uncertainty (`count_p95_low/high`); multistatic placement recipe with **100% coverage for 1–4 occupants at N=5 nodes (synthetic physics)** | **[I]** (sota-2026-05-22 R6.2.5, ADR-113) |
### 1.3 Vital signs (HR / BR)
| Method | Year | Metric | Tag |
|--------|------|--------|-----|
| PhaseBeat (ACM Health) | 2020 | HR median error **1.19 bpm**; BR median error **0.25 breaths/min** | **[V]** |
| MDPI Sensors 24(7):2111 non-contact HR | 2024 | HR accuracy 96.8%, **median error 0.8 bpm** | **[V]** |
| PulseFi (arXiv 2510.24744) | 2025 | Low-cost ML cardiopulmonary + **apnea** monitoring from CSI | **[V]** (existence; numbers not extracted) |
| mmWave FMCW vitals (60 GHz class) | 2023–2026 | HR MAE typically 1–3 bpm at 1–3 m, single subject; age-balanced reference dataset published (Sci Data 2026) | dataset **[V]**; MAE range **[K]** |
| Contactless blood pressure (WiFi-band) | — | **NEGATIVE** — below classical physics floor; recoverable only via quantum magnetometry path | **[I]** (R13/R20 arc, ADR-114) |
| **RuView** | 2026 | `wifi-densepose-vitals` (ADR-021) extracts HR/BR from ESP32 CSI; chest-centric placement gives **+27 pp coverage** for vitals cogs (synthetic) | **[I]** — **no accuracy-vs-ECG validation number exists in-repo yet; do not claim one** |
**Bar**: published single-subject, line-of-sight, 1–3 m WiFi HR is ~0.8–1.2 bpm median error **[V]**. Nobody credibly publishes multi-person, through-wall, walking-subject HR at that accuracy — that is open territory.
### 1.4 Localization (ToA / CRLB)
| Method | Year | Metric | Tag |
|--------|------|--------|-----|
| 802.11mc FTM | shipped | 1–2 m typical accuracy | **[V]** (FTM survey, arXiv 2509.03901) |
| 802.11az (+ 802.11bk) | released | **sub-1 m**, 160 MHz channels, secured ranging, HE-LTF repetitions | **[V]** |
| AI single-link decimeter localization | 2025 | **0.63 m average error** single-link, beating Widar2.0 / Dynamic-MUSIC | **[V]** |
| SpotFi / Chronos / Widar lineage | 2015–2021 | 0.4–1 m with multi-AP CSI AoA/ToF | **[K]** |
| **RuView** | 2026 | CRLB / Fisher-information machinery in `ruvector/src/viewpoint/geometry.rs`; tomography ISTA voxel grid; **theoretical** limits derived internally: 30–60 cm at 16 nodes/1 m spacing, 8.8 cm information-theoretic dense limit | **[I]** (rf-topological-sensing doc 09 — synthetic derivations, no bench numbers) |
### 1.5 Through-wall
| Method | Year | Metric | Tag |
|--------|------|--------|-----|
| RF-Pose / RF-Pose3D (MIT, FMCW 5.4–7.2 GHz) | 2018 | Through-wall skeletal pose, ~specialized radar not commodity WiFi | **[K]** |
| Commodity 2.4 GHz through-wall imaging (arXiv 1903.03895) | 2019 | Coarse imaging through walls with commodity WiFi | **[V]** (existence) |
| Radio tomographic imaging (RTI) lineage | 2010–2013 | Through-wall tracking via RSS networks, ~0.5–1 m tracking error | **[V]** (papers) / error figure **[K]** |
| LeakyBeam (NDSS 2025) | 2025 | Through-wall **occupancy** at 20 m, passive, commodity | **[V]** |
| **RuView** | 2026 | RF tomography module (`tomography.rs`, ISTA L1 voxel solver) + CIR (ADR-134) exist as code; **PABS structure detection: 1,161× static / 9.36× dynamic intruder lift (synthetic)** | **[I]** |
Notably, the 2025–2026 web literature shows through-wall *pose* (not just presence) on commodity WiFi remains essentially where it was in 2019 — no verified commodity-WiFi through-wall pose benchmark surfaced in our searches. The frontier moved to privacy attacks (BFI) instead.
### 1.6 Identity / re-ID (capability and threat simultaneously)
| Method | Year | Metric | Tag |
|--------|------|--------|-----|
| BFId (KIT, ACM CCS 2025) | 2025 | **~99.5% (near-100%) re-ID across 197 subjects** from beamforming feedback alone, ≥5 s of BFI | **[V]** (also BFLD survey §4.1) |
| Transformer CSI identification | 2025 | **99.82%** on stationary subjects | **[V]** |
| WhoFi (arXiv 2507.12869) | 2025 | Deep person re-ID via WiFi channel encoding, ~95% rank-1 class results | existence **[V]**; exact number **[K]** |
| Wi-Gait | 2023 | 92.9% over 10 subjects, robust to walking cofactors | **[V]** |
| **RuView** | 2026 | AETHER contrastive re-ID embeddings (ADR-024) in pose tracker; **BFLD**: first *defensive* identity-leak detector (identity_risk_score) — the literature attacks, RuView audits | **[I]** |
### 1.7 Adjacent modality: mmWave radar (the accuracy ceiling WiFi is chasing)
| Method | Year | Metric | Tag |
|--------|------|--------|-----|
| mmChainPose | 2025 | **27.0 mm MPJPE** / 0.8706 OKS on MARS (mmWave point cloud) | **[V]** |
| ProbRadarM3F (arXiv 2405.05164) | 2024–25 | SOTA AP across joints, probability-map fusion | **[V]** |
| Seeed MR60BHA2-class 60 GHz FMCW | shipped | Commodity $15 HR/BR/presence module — already in RuView's hardware table | **[I]** |
mmWave is ~6× better than the best WiFi MPJPE (27 mm vs 160 mm) **[V]**. The strategic implication: WiFi will not beat mmWave on raw geometry; it wins on ubiquity, cost, through-wall propagation, and standardized waveforms (§2). RuView already hedges with the ESP32-C6 + MR60BHA2 fusion node. **[I]**

## 2. IEEE 802.11bf — status and implications
**Status (verified)**: IEEE **802.11bf-2025 is ratified and published** (IEEE SA lists the amendment; ratification late 2024 / publication 2025) **[V]**. It amends MAC/PHY of HE (Wi-Fi 6) and EHT (Wi-Fi 7) plus DMG/EDMG (60 GHz) to support WLAN sensing in 1–7.125 GHz and >45 GHz bands **[V]**. The Wi-Fi Alliance has Wi-Fi Sensing as an active certification work area built on 802.11bf (presence/proximity, gestures, vital signs) **[V]**. Market reports claim >47 chipset vendors with 802.11bf-compatible programs as of early 2026 — single weak source, treat as directional **[V, low confidence]**.
**What it implies for RuView**:
1. **Sounding-on-demand becomes standard.** 802.11bf defines a sensing-measurement procedure (sensing initiator/responder, trigger-based sounding, threshold-based reporting). Today RuView relies on Espressif's vendor CSI API and Nexmon firmware patches; post-bf, commodity Wi-Fi 7 silicon will expose scheduled sensing measurements without firmware hacks. The rvCSI normalized `CsiFrame` schema is the right abstraction layer to absorb a future bf adapter (`rvcsi-adapter-*`). **[I]**
2. **The moat moves up the stack.** When every router can sense, raw CSI access stops being differentiating. Differentiators become: multistatic fusion, coherence gating / anti-hallucination, calibration mechanisms, witness-grade verification, and privacy auditing — exactly RuView's existing bets (ADR-029/135/150/028, BFLD). **[I]**
3. **Privacy pressure intensifies.** 802.11bf standardizes the capability that BFId/LeakyBeam exploit. BFLD's identity-leak detection and the ADR-105–109 privacy/PQC chain become regulatory assets, not nice-to-haves. **[V]+[I]**
4. **Threshold-based reporting** in bf (report only when channel changes exceed threshold) is architecturally the same idea as RuView's coherence gate — validation that the gate belongs at the protocol layer. **[K]** (bf reporting detail from training knowledge)

## 3. RF foundation model landscape ("GPT for RF")
Verified 2025–2026 attempts, all young, none dominant:
| Model | Approach | Downstream tasks | Tag |
|-------|----------|------------------|-----|
| **LWM (Large Wireless Model)** | Pretrained on large-scale CSI → general channel embeddings | LoS/NLoS, beats raw features in low-data regimes | **[V]** |
| **LatentWave** (arXiv 2606.06373) | JEPA pretraining on wireless spectrograms + CSI | RF classification, 5G NR positioning, beam prediction, LoS/NLoS | **[V]** |
| **WirelessJEPA** (arXiv 2601.20190) | Multi-antenna spatio-temporal latent prediction | Cross-task transfer | **[V]** |
| **IQFM** | Contrastive SSL on raw I/Q | Modulation classification, beam prediction, RF fingerprinting, few-shot | **[V]** |
| **Multimodal Wireless FMs** (arXiv 2511.15162), **WMFM** (arXiv 2512.23897), **SoM** (arXiv 2506.07647) | Vision + RF multimodal for 6G ISAC | Sensing-communication integration | **[V]** |
| **DeepSig OmniSIG** | Commercial AI-native RF sensing, 500 MHz/GPU spectrum | Signal ID (LTE/5G/Wi-Fi) | **[V]** |
**Critical observation**: every verified RF foundation model targets *communication-side* tasks (beam prediction, LoS/NLoS, modulation, positioning). **None of them is a human-sensing foundation model** — none pretrains for pose/vitals/identity invariances. ADR-150's measured negative result is the sharpest data point in this space: pose-contrastive pretraining across subjects **failed on MM-Fi because the invariance is not in the data** (loss never left the ln(B) floor) **[I]**. The literature has not yet published this failure mode; the field's "GPT for RF sensing" narrative is ahead of its evidence. The defensible foundation-model objective (per ADR-150 §3.5–3.6) is **reduce few-shot calibration cost**, not zero-shot invariance. **[I]**

## 4. "Beyond SOTA" for RuView — precise definition
Targets below are **bar definitions**, not claims. RuView numbers in the "current" column are measured [I]; targets must be proven via the AetherArena witness protocol (ADR-149) before being asserted anywhere.
| Capability | Published SOTA (2026) | RuView measured today | RuView beyond-SOTA target | Key obstacle |
|------------|----------------------|----------------------|---------------------------|--------------|
| Pose, in-domain (MM-Fi) | GraphPose-Fi 160.6 mm MPJPE; MultiFormer 72.25% torso-PCK@20 **[V]** | **81.63% torso-PCK@20** (already > published) **[I]** | Hold #1 under leakage-free audit + per-joint tables published with witness rows | Protocol fragmentation; reviewers distrust WiFi-pose numbers |
| Pose, cross-subject zero-shot | ~collapse everywhere; PerceptAlign PCK@20 44.2 cross-layout **[V]** | 11.6% torso zero-shot; 63–65% in-harness official split **[I]** | Stop chasing it (measured dead end); instead **few-shot frontier** below | Subject-distribution shift is in the data, not the model (ADR-150 §3.2) |
| Pose, deployment calibration | **No published per-room adapter mechanism found** | **11 KB LoRA, 100–200 frames → 72.5%; cross-env K=5 → 60.1%** **[I]** | ≤20 frames → ≥70% PCK@20, adapter ≤11 KB, 30 s on-site; publish as the first calibration-service benchmark | Needs diverse-room capture fleet to validate beyond MM-Fi |
| Presence/motion (commodity) | 92.6% across 10 M routers **[V]** | Synthetic placement recipe 100% coverage N=5 **[I]** | ≥99% presence with calibrated p95 bounds on $6–15 ESP32 mesh, bench-validated | All placement numbers are synthetic; Tier-2.3 bench validation outstanding |
| Person count | ~90–97% lab, ≤5 people **[K]** | cog ships uncertainty intervals **[I]** | Exact count 1–6 people ≥95% with honest intervals, multistatic, real bench | Multi-person CSI superposition; no public multi-occupancy benchmark |
| Vital signs HR | 0.8–1.2 bpm median, single subject, LoS, 1–3 m **[V]** | No in-repo ECG-validated number — **must not be claimed** | ≤1.5 bpm MAE vs ECG ground truth, *multi-person or through-wall*, witness-bundled | R13 physics floor: ~5 dB shortfall at distance; needs chest-centric placement + PABS |
| Vital signs BP | NEGATIVE at WiFi band (matches internal R13) | nvsim quantum path only **[I]** | First validated quantum-classical fused bedside vitals (ADR-114) | NV-diamond hardware maturity, 2028+ |
| Localization | 0.63 m single-link AI; sub-1 m 802.11az **[V]** | CRLB machinery, no bench number **[I]** | ≤30 cm multistatic on ESP32 mesh (internal theory says feasible at N=16) | ESP32 clock sync / phase offset (TDM protocol exists, unproven at this accuracy) |
| Through-wall | Occupancy yes (LeakyBeam); commodity pose: nothing credible **[V]** | tomography + CIR code, PABS 9.36× lift (synthetic) **[I]** | First witnessed commodity-WiFi through-wall *person localization* (not pose) ≤1 m | Wall attenuation eats the R6.1 4.7 dB multi-scatterer budget |
| Identity / re-ID | ~99.5% @ 197 subjects (attack) **[V]** | AETHER + **BFLD defensive auditing** (no published competitor) **[I]** | Ship the first identity-leak risk score with DP budget hook; keep re-ID opt-in only | Calibrating risk score at 802.11ax 4/2-bit quantization (BFLD open Q2) |
| Verification | **Nothing comparable published** — no WiFi-sensing paper ships deterministic re-verification | ADR-028 witness bundles, SHA-256 proof, 7/7 self-verify, 1,031+ tests **[I]** | Make witness-grade reproduction the *expected* standard: every public claim = one-command verification | Community adoption, not technology |
| Foundation encoder | Comms-task FMs only (LWM/JEPA family) **[V]** | Masked-CSI + coherence head planned; pose-contrastive refuted **[I]** | First *sensing* FM whose acceptance metric is calibration-sample reduction (frames-to-72% halved) | SSL must match production CSI pipeline (ADR-149 resampling risk) |
---
## 5. Where RuView already matches/exceeds published work
1. **In-domain MM-Fi pose** — 81.63% torso-PCK@20 vs MultiFormer 72.25%, metric- and protocol-matched (issue #876). **[I]**
2. **Deployment-calibration mechanism** — the 11 KB LoRA per-room adapter with measured frames-to-accuracy curves (§3.4–3.6 of ADR-150) has no published equivalent; the literature is still arguing about zero-shot generalization that ADR-150 measured to be a data property.
3. **Deterministic witness verification** — ADR-028's SHA-256 pipeline proof + self-verifying bundles exceeds the reproducibility practice of every WiFi-sensing paper surveyed (none ship deterministic re-verification).
4. **Multistatic cost point** — $6–15/node ESP32 mesh with TDM sync, channel hopping, placement recipes (ADR-113) vs literature setups using Intel 5300/AX210 laptops or USRPs; ~$30/bed vs $3,000 clinical monitor framing (R16).
5. **Defensive identity auditing (BFLD)** — the field publishes attacks (BFId, LeakyBeam, WhoFi); RuView is building the only detector/auditor, plus a PQC-hardened federation privacy chain (ADR-105–109) with no published counterpart.
6. **Anti-hallucination coherence gating** — confidence gated by RF integrity (ADR-135, ADR-150 §2.4); WiFi-pose papers uniformly lack a "the model knows when the channel is bad" signal.
7. **Negative-result discipline** — physics floors (R13 BP, R6.1 4.7 dB), refuted pose-contrastive pretraining — published SOTA papers do not report these, which inflates the apparent literature bar.
## 6. Where RuView lags
1. **Bench validation** — nearly all multistatic/placement/tomography numbers are synthetic-physics; the 92.6%-on-10M-routers deployment **[V]** is real-world evidence at a scale RuView cannot approach.
2. **Vital-sign ground truth** — no in-repo ECG/respiration-belt validated HR/BR error; published work has 0.8 bpm median **[V]**. This is the most urgent claim gap.
3. **Raw geometric accuracy** — mmWave (27 mm MPJPE **[V]**) and even best-WiFi MPJPE (160.6 mm **[V]**) have no RuView MPJPE counterpart published; AetherArena reports PCK only.
4. **802.11bf-native capture** — RuView is on vendor CSI APIs and Nexmon patches; no bf sensing-procedure adapter exists yet in rvCSI.
5. **Multi-person pose** — Person-in-WiFi-3D does end-to-end multi-person at 54 FPS **[V]**; RuView's pose path is effectively single-person (multi-person exists only in count/placement work).
6. **Dataset scale and diversity** — MM-Fi only; ADR-150 §3.3 shows the binding constraint is room/device/protocol diversity, which requires the capture fleet that doesn't exist yet.
## 7. Strategic synthesis
The 2026 bar is bimodal: **lab in-domain numbers are saturated** (PCK@50 > 95%, HR < 1 bpm) and **deployment numbers are collapsed** (cross-layout PCK@20 ≈ 44, zero-shot cross-subject ≈ 11%). 802.11bf-2025 commoditizes raw sensing; foundation models commoditize comms-side embeddings. "Beyond SOTA" for RuView is therefore *not* a leaderboard delta — it is owning the three layers the field hasn't built: **(a)** witnessed, deterministic, leakage-audited evaluation; **(b)** the few-shot calibration service (11 KB adapters) as the deployment answer the zero-shot literature lacks; **(c)** the privacy/integrity layer (BFLD + coherence gate) that 802.11bf-era regulation will demand. Each row in §4's target table is gated on the AetherArena witness protocol — a target becomes a claim only when it ships with a one-command reproduction.
