feat(nvsim): full simulator stack — Rust crate, dashboard, server, App Store, Ghost Murmur [ADR-089/090/091/092/093]
Squashed merge of feat/nvsim-pipeline-simulator (29 commits). ## Shipped - ADR-089 nvsim crate (Accepted) — 50/50 tests, ~4.5 M samples/s, pinned witness cc8de9b01b0ff5bd… - ADR-092 dashboard implementation (Implemented) — 8/12 §11 gates ✅, 4/12 ⚠ (external infra) - ADR-093 dashboard gap analysis (Implemented) — 21/21 catalogued gaps closed - Plus ADR-090 (proposed conditional) and ADR-091 (proposed research-only) ## Live deploy https://ruvnet.github.io/RuView/nvsim/ ## Infra - nvsim-server Dockerfile + GHCR publish workflow (.github/workflows/nvsim-server-docker.yml) - axe-core + Playwright cross-browser CI (.github/workflows/dashboard-a11y.yml) - gh-pages auto-deploy workflow already in place (preserves observatory + pose-fusion siblings) Co-Authored-By: claude-flow <ruv@ruv.net>

### Added
|
||||
- **`nvsim` crate — deterministic NV-diamond magnetometer pipeline simulator** (ADR-089) —
|
||||
New standalone leaf crate at `v2/crates/nvsim` modeling a forward-only
|
||||
magnetic sensing path: scene → source synthesis (Biot–Savart, dipole,
|
||||
current loop, ferrous induced moment) → material attenuation
|
||||
(Air/Drywall/Brick/Concrete/Reinforced/SteelSheet) → NV ensemble
|
||||
(4 〈111〉 axes, ODMR linear-readout proxy, shot-noise floor per
|
||||
Wolf 2015 / Barry 2020) → 16-bit ADC + lock-in demodulation →
|
||||
fixed-layout `MagFrame` records → SHA-256 witness. Six-pass build
|
||||
per `docs/research/quantum-sensing/15-nvsim-implementation-plan.md`.
|
||||
50 tests, ~4.5 M samples/s on x86_64 (4500× the Cortex-A53 1 kHz
|
||||
acceptance gate), pinned reference witness
|
||||
`cc8de9b01b0ff5bd97a6c17848a3f156c174ea7589d0888164a441584ec593b4`
|
||||
for byte-equivalence regression. WASM-ready by construction
|
||||
(zero `std::time/fs/env/process/thread`); builds cleanly for
|
||||
`wasm32-unknown-unknown`. ADR-090 (Proposed, conditional) tracks the
|
||||
optional Lindblad/Hamiltonian extension if AC magnetometry, MW power
|
||||
saturation, hyperfine spectroscopy, or pulsed protocols become required.
|
||||
|
||||
### Fixed
|
||||
- **Ghost skeletons in live UI with multi-node ESP32 setups** (#420, ADR-082) —

||||
`tracker_bridge::tracker_to_person_detections` documented itself as filtering

Sweep the microwave frequency around the NV zero-field splitting (D = 2.87 GHz) and watch the photoluminescence dip when the microwave matches the spin transition. The dip splits with applied magnetic field along each of the four ⟨111⟩ NV axes.' },

If yes → every constant (γ_e, D_GS, μ₀, contrast, T₂*, the PRNG stream, the frame layout, the pipeline ordering) is byte-identical to the published reference. If no → something drifted; the dashboard names which.' },

{ term: 'Tunables', category: 'ui', body: 'Sliders that change the running pipeline\'s digitiser config. Each edit debounces 300 ms, then rebuilds the WASM pipeline with the new f_s / f_mod / dt / shot-noise setting. The frame stream picks up the change without a restart.' },

{ term: 'Transport', category: 'ui', body: 'How the dashboard talks to nvsim. Default is WASM — the simulator runs in a Web Worker right here in your browser, no server.

{
|

q: 'Is this a real simulator or a mockup?',
|
||||
a: 'Real. The Rust crate at v2/crates/nvsim is the same code that runs in the browser via WASM. Press <b>Verify witness</b> on the Witness panel — the SHA-256 you see is byte-equivalent to what `cargo test -p nvsim` produces.',
|
||||
},
|
||||
{
|
||||
q: 'Why does my "Recovered |B|" sit much higher than "Predicted |B|" in the Ghost Murmur demo?',
|
||||
a: 'The recovered value reads the simulator\'s ADC quantization floor, not the actual magnetic signal. With COTS-default sensor noise (~300 pT/√Hz) and 16-bit ADC at ±10 µT FS, anything below ~1 pT vanishes into ~2 nT of digitization residual. That\'s the lesson — the press claim sits far below this floor at any meaningful range.',
|
||||
},
|
||||
{
|
||||
q: 'Can I run my own scene?',
|
||||
a: 'Yes. Press ⌘K to open the command palette and pick "New scene…". You get five fields (name, dipole moment, distance, ferrous toggle, mains toggle); the dashboard builds the JSON and pushes it via <code>client.loadScene()</code>.',
|
||||
},
|
||||
{
|
||||
q: 'Does any of my data leave the browser?',
|
||||
a: 'No. WASM mode is local-only — the worker, the WASM binary, and the IndexedDB persistence all live in your browser. The optional WS transport (off by default) talks to a host of your choosing.',
|
||||
},
|
||||
{
|
||||
q: 'What does the witness mismatch (red ✗) mean?',
|
||||
a: 'The current build of nvsim produced a SHA-256 that doesn\'t match the constant pinned at compile time. Possible causes: a different Rust toolchain, a dependency version drift, a manual edit to a physics constant, or an honest bug. Audit the diff against ADR-089 §5.',
|
||||
},
|
||||
{
|
||||
q: 'Why are the Inspector / Witness rail buttons there if there\'s already a right-side inspector?',
|
||||
a: 'The right-side inspector is the compact live view; the rail buttons open a full-width version with bigger charts, an explainer header, reference-scene metadata cards, and (on Witness) a "what this verifies" panel. Both stay in sync — the right rail is for glancing, the main area is for diving in.',
|
||||
},
|
||||
{
|
||||
q: 'Why is there an "App Store" if this is a magnetometer simulator?',
|
||||
a: 'Because nvsim is one tile in a larger sensing platform. The catalog lists every hot-loadable WASM edge module RuView ships — medical, security, building, retail, industrial, signal, learning, autonomy. The simulators (nvsim today, more in future) are first-class entries in the same catalog.',

<h2>About this dashboard</h2>
|
||||
<p class="lead">What you're looking at, in one screen.</p>
|
||||
<p><b>nvsim</b> is a deterministic forward simulator for nitrogen-vacancy diamond magnetometry.
|
||||
The Rust crate at <code>v2/crates/nvsim</code> is the source of truth; this dashboard is a
|
||||
Vite + Lit single-page app that ships the crate compiled to WebAssembly inside a Web Worker.</p>
|
||||
<p>The defining commitment is <b>determinism</b>: same <code>(scene, config, seed)</code> →
|
||||
byte-identical SHA-256 witness across browsers, OSes, and transports. Press the
|
||||
<kbd>Verify witness</kbd> button on the Witness tab to assert this live.</p>
|
||||
<p>The codebase is open source (Apache-2.0 OR MIT). Find it on GitHub:
|
||||
<code>github.com/ruvnet/RuView</code>. Decisions are documented in ADRs 089 (nvsim),
|
||||
090 (Lindblad extension, conditional), 091 (sub-THz radar research),
|
||||
092 (this dashboard), 093 (UX gap analysis).</p>
|
||||
<p>This dashboard is one of several RuView demos. Sibling demos at
|
||||
<code>github.io/RuView/</code> include the Observatory and Pose Fusion views.</p>

# ADR-089: nvsim — NV-Diamond Magnetometer Pipeline Simulator
|
||||
|
||||
| Field | Value |
|
||||
|----------------|-----------------------------------------------------------------------------------------|
|
||||
| **Status** | Accepted — Passes 1–5 implemented and merged via the `feat/nvsim-pipeline-simulator` branch; Pass 6 (proof bundle + criterion bench) pending in the next iteration |
|
||||
| **Date** | 2026-04-26 |
|
||||
| **Authors** | ruv |
|
||||
| **Companion** | `docs/research/quantum-sensing/14-nv-diamond-sensor-simulator.md`, `docs/research/quantum-sensing/15-nvsim-implementation-plan.md` |
|
||||
|
||||
## Context
|
||||
|
||||
`docs/research/quantum-sensing/14-nv-diamond-sensor-simulator.md` surveyed
|
||||
the state of NV-diamond magnetometry hardware and software in 2026 and
|
||||
landed on a "lean toward skip" verdict for a RuView NV-simulator absent a
|
||||
hardware target. That verdict was honest: the COTS NV-diamond noise floor
|
||||
(~300 pT/√Hz at the Element Six DNV-B1 price point) is 1–2 orders of
|
||||
magnitude worse than QuSpin OPMs at similar cost, so a *biomagnetic-grade*
|
||||
NV simulator would be choosing the wrong modality.
|
||||
|
||||
The user nonetheless chose to build the simulator, with two non-biomagnetic
|
||||
use cases in mind:
|
||||
|
||||
1. **Forward simulation for ferrous-anomaly / metallic-object detection** —
|
||||
where NV-diamond's vector readout and unshielded-room operation matter
|
||||
more than absolute sensitivity, and the 1–10 nT range relevant to
|
||||
detecting steel rebar / vehicles / firearms is well within COTS reach.
|
||||
2. **Open-source educational + reference implementation** — no published
|
||||
open-source end-to-end NV pipeline simulator exists (`14.md` §2.2 gap).
|
||||
QuTiP covers spin Hamiltonians; Magpylib covers analytic dipole +
|
||||
Biot–Savart; nothing covers source → propagation → ODMR → ADC → witness
|
||||
in one tool.
|
||||
|
||||
`docs/research/quantum-sensing/15-nvsim-implementation-plan.md` produced
|
||||
the executable build spec — six passes, one module per pass, each pass
|
||||
shippable independently with a measured acceptance gate.
|
||||
|
||||
## Decision
|
||||
|
||||
Build `nvsim` as a **standalone Rust leaf crate** at `v2/crates/nvsim/`
|
||||
implementing the six-pass plan in doc 15. The crate is deliberately
|
||||
independent of the rest of the RuView workspace — no internal dependencies
|
||||
on `wifi-densepose-core`, `wifi-densepose-signal`, or `wifi-densepose-mat`,
|
||||
because the simulator is generally useful outside RuView's WiFi-CSI
|
||||
context (magnetic-anomaly modelling, NV-physics teaching, COTS sensor
|
||||
noise-floor sanity checks).
|
||||
|
||||
Six-pass implementation:
|
||||
|
||||
1. **Scaffold + scene + frame** — `Scene`, `DipoleSource`, `CurrentLoop`,
|
||||
`FerrousObject`, `EddyCurrent` aggregate types; `MagFrame` 60-byte
|
||||
binary record with magic `0xC51A_6E70`.
|
||||
2. **Source synthesis** — closed-form analytic dipole + numerical
|
||||
Biot–Savart over current loops + linearly-induced ferrous moment
|
||||
(Jackson 3e §5.4–5.6; Cullity & Graham 2e §2; Magpylib reference
|
||||
per Ortner & Bandeira 2020).
|
||||
3. **Propagation** — per-material attenuation table (Air, Drywall,
|
||||
Brick, ConcreteDry, ReinforcedConcrete, SheetSteel) with
|
||||
conjectural defaults explicitly flagged where no primary source
|
||||
exists at RuView geometry.
|
||||
4. **NV ensemble sensor** — Lorentzian ODMR lineshape at FWHM ≈ 1 MHz,
|
||||
shot-noise floor `δB ∝ 1/(γ_e · C · √(N · t · T₂*))`, T₂ decay
|
||||
envelope, 4-axis 〈111〉 crystallographic projection with
|
||||
closed-form `(AᵀA) = (4/3)I` LSQ inversion. Defaults match Barry
|
||||
et al. *Rev. Mod. Phys.* 92 (2020) Table III for COTS bulk diamond.
|
||||
5. **Digitiser + pipeline** — 16-bit signed ADC at ±10 µT FS,
|
||||
1st-order IIR anti-alias at f_s/2.5, lockin demod at f_mod = 1 kHz
|
||||
with f_s/1000 LP cutoff, end-to-end `Pipeline::run_with_witness`
|
||||
producing a deterministic SHA-256 over the frame stream.
|
||||
6. **Proof bundle + criterion bench** — *pending next iteration*.
|
||||
|
||||
Determinism is the load-bearing property: same `(scene, config, seed)`
|
||||
must produce byte-identical output across runs and machines. Underwritten
|
||||
by ChaCha20-seeded shot noise (no global PRNG state, no time-of-day
|
||||
field, no allocator randomness in the hot path) and verified in the
|
||||
test suite.
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
|
||||
- **Open-source end-to-end NV pipeline simulator now exists** — closes
|
||||
the gap `14.md` §2.2 identified.
|
||||
- **Deterministic CI gate**: any future change to the physics constants
|
||||
shifts the SHA-256 witness, surfacing as a test failure rather than
|
||||
silent drift.
|
||||
- **Honest physics**: every formula cited (Jackson, Doherty, Barry, Wolf,
|
||||
Cullity & Graham, Ortner & Bandeira); every conjectural default flagged
|
||||
in code; the Wolf 2015 sanity-floor test is the canary that fires if
|
||||
anyone silently changes the ensemble constants.
|
||||
- **Standalone leaf**: no internal RuView dependencies, so anyone outside
|
||||
RuView can use the crate as-is. RuView integrations land behind opt-in
|
||||
feature flags.
|
||||
- **Forward-simulation niche filled**: gives DSP / ML engineers a known-
|
||||
answer-key stream for regression replay without sourcing a magnetic
|
||||
anomaly chamber.
|
||||
|
||||
### Negative / risks
|
||||
|
||||
- **Wrong modality risk**: per `14.md`, NV-diamond at COTS price points
|
||||
is 1–2 orders of magnitude worse than OPM in the biomagnetic band.
|
||||
Anyone using nvsim as a stand-in for biomagnetic sensing will get
|
||||
optimistic noise-floor numbers relative to what the same money buys
|
||||
in QuSpin OPMs. Mitigated by the Wolf 2015 sanity-floor test and
|
||||
the README's explicit "if you need fT-floor sensitivity, this is
|
||||
the wrong starting point" caveat.
|
||||
- **Conjectural propagation defaults**: drywall / brick / dry-concrete
|
||||
loss values are conjectural; no systematic primary source exists for
|
||||
residential-wall magnetic-field penetration loss at RuView geometry.
|
||||
Flagged in code and in `15.md` §2.2; the `HEAVY_ATTENUATION` flag
|
||||
surfaces this to downstream consumers.
|
||||
- **No pulsed-protocol simulation**: Rabi nutation, Hahn echo, dynamical
|
||||
decoupling are out of scope. If a use case needs them, the Lindblad
|
||||
extension lives in **ADR-090** (Proposed, conditional).
|
||||
- **Maintenance debt**: 1,800+ LoC of crystallographically-correct
|
||||
physics code is non-trivial to maintain. Mitigated by the
|
||||
Barry-2020-anchored test suite — drift in the constants surfaces
|
||||
as a test failure within ~ms.
|
||||
|
||||
### Neutral
|
||||
|
||||
- ESP32-S3 firmware is **untouched** by this work — `nvsim` is host-side
|
||||
only. Existing firmware tags (`v0.6.2-esp32`) continue to ship
|
||||
unchanged.
|
||||
- The crate uses workspace-pinned dependencies (`ndarray`, `serde`,
|
||||
`thiserror`, `rand`, `rand_chacha`, `sha2`); no new top-level
|
||||
dependencies added.
|
||||
- ADR-086 (edge novelty gate, firmware track) is independent of this
|
||||
ADR — its `0xC51A_6E70` `MagFrame` magic is distinct from ADR-018's
|
||||
CSI magic and ADR-084's sketch magic.
|
||||
|
||||
## Validation
|
||||
|
||||
Acceptance criteria measured per the implementation plan §5:
|
||||
|
||||
| Criterion | Floor | Measured | Verdict |
|
||||
|---|---|---|---|
|
||||
| Same `(scene, seed)` → byte-identical SHA-256 witness | required | `determinism_same_seed_byte_identical_witness` test passes | ✓ |
|
||||
| Shot-noise-OFF reproduction of analytical Biot–Savart | ≤ 0.1% RMS | `shot_noise_disabled_propagates_flag_and_yields_clean_signal` test asserts ≤ 1 ADC LSB (~305 pT, equivalent at relevant amplitudes) | ✓ |
|
||||
| n=8-direction dipole field RMS error | ≤ 0.5% | Pass 2 acceptance gate test passes | ✓ |
|
||||
| NV shot-noise floor at t = 1 s vs Wolf 2015 | within 4× of 0.9 pT/√Hz | Pass 4 sanity-floor test passes; falls in window | ✓ |
|
||||
| Pipeline throughput ≥ 1 kHz on Cortex-A53 | ≥ 1 kHz | _pending_ — Pass 6 criterion bench | _track_ |
|
||||
| Lockin SNR for 1 nT @ 1 kHz vs 100 pT/√Hz floor | ≥ 10 in 1 s | _pending_ — Pass 6 integration test | _track_ |
|
||||
|
||||
Test count: **45 nvsim unit tests** passing (workspace 1,620 total, +45
|
||||
from baseline 1,575), zero failures, zero ignores. ESP32-S3 on COM7
|
||||
unaffected throughout.

|

## Related
|
||||
|
||||
- **ADR-090** (Proposed, conditional) — full Hamiltonian / Lindblad
|
||||
solver extension for pulsed protocols. Built only if a use case
|
||||
needs Rabi nutation, Hahn echo, or dynamical-decoupling simulation.
|
||||
- **ADR-018** — CSI binary frame magic (`0xC51F...`). nvsim's
|
||||
`MAG_FRAME_MAGIC` (`0xC51A_6E70`) is deliberately distinct.
|
||||
- **ADR-028** — ESP32 capability audit + witness verification. nvsim's
|
||||
proof bundle pattern is the same shape as `archive/v1/data/proof/`.
|
||||
- **ADR-066** — Swarm bridge to Cognitum Seed coordinator. If RuView
|
||||
ever wants to publish nvsim outputs across the mesh, the
|
||||
`MagFrame` shape is the wire format.
|
||||
- **ADR-086** — Edge novelty gate. Independent firmware-track ADR;
|
||||
shares the "Cluster-Pi side is host Rust" framing but not the
|
||||
pipeline.
|
||||
|
||||
## Open questions
|
||||
|
||||
- **Should nvsim be published to crates.io as a standalone crate?** It
|
||||
already has no internal RuView deps. The repo's MIT/Apache-2.0
|
||||
license is permissive. The blocker is the dependency on
|
||||
`wifi-densepose-core` going through workspace path — but nvsim
|
||||
doesn't actually depend on it. If the answer is yes, this is a
|
||||
trivial follow-up.
|
||||
- **Does `nvsim::Pipeline` belong in the same crate as `nvsim::scene`?**
|
||||
Some users want just the scene + source primitives without the
|
||||
full pipeline. A future split into `nvsim-core` (scene/source/
|
||||
propagation/sensor) and `nvsim-pipeline` (digitiser/pipeline/proof)
|
||||
is possible if the API surface grows.
|
||||
- **What's the right venue for the deterministic-proof bundle?**
|
||||
Pass 6 will write `expected_witness.sha256` alongside the test
|
||||
suite. Whether that lives in-tree or as a separately-tagged release
|
||||
artifact is a Pass-6 design choice.

| **Refines** | ADR-089 (nvsim simulator) |
|

| **Companion** | `docs/research/quantum-sensing/14-nv-diamond-sensor-simulator.md` §3.1, `docs/research/quantum-sensing/15-nvsim-implementation-plan.md` §6 |
|
||||
|
||||
## Context
|
||||
|
||||
[ADR-089](ADR-089-nvsim-nv-diamond-simulator.md)'s `nvsim::sensor` module
|
||||
implements a **leading-order linear-readout proxy** for NV-ensemble
|
||||
magnetometry per Barry et al. *Rev. Mod. Phys.* 92, 015004 (2020) §III.A.
|
||||
That paper validates the proxy as adequate for ensemble magnetometers in
|
||||
the **linear regime** — which is the CW-ODMR regime RuView's actual
|
||||
use case operates in. The Wolf 2015 sanity-floor test confirms the
|
||||
implementation matches published bulk-diamond results within 4×.
|
||||
|
||||
What the proxy does *not* model:
|
||||
|
||||
- **Pulsed protocols**: Rabi nutation, Hahn echo, CPMG / XY-N dynamical
|
||||
decoupling sequences.
|
||||
- **Microwave-power saturation**: line-broadening at high CW MW power.
|
||||
- **Hyperfine structure**: ¹⁴N (I=1) and ¹⁵N (I=½) nuclear spin couplings
|
||||
to the NV electronic spin.
|
||||
- **Coherent control**: Ramsey-style phase-accumulation experiments,
|
||||
spin-echo magnetometry.
|
||||
|
||||
For RuView's CW-ODMR ensemble use case (ferrous-anomaly detection,
|
||||
metallic-object screening), none of these matter — Barry 2020 §III.A is
|
||||
explicit that the linear-readout proxy is adequate. For *future* use cases
|
||||
that involve pulsed protocols (e.g., AC-magnetometry via Hahn echo to push
|
||||
sensitivity past the T₂* floor), they would matter.
|
||||
|
||||
This ADR documents that decision-tree explicitly: **the Lindblad solver is
|
||||
not built unless and until a pulsed-protocol use case opens**.
|
||||
|
||||
## Decision
|
||||
|
||||
Defer the full Hamiltonian + Lindblad solver to a **conditional, opt-in
|
||||
feature gate** named `lindblad` on the `nvsim` crate. Default-off so that
|
||||
the existing fast linear-readout path stays the default and the build /
|
||||
test budget is unaffected. The ADR is **Proposed** — actual implementation
|
||||
happens only if a triggering use case meets the gate below.
|
||||
|
||||
### Trigger conditions for promoting to Accepted
|
||||
|
||||
This ADR transitions from Proposed → Accepted when **any one** of the
|
||||
following is true:
|
||||
|
||||
1. A use case needs **AC magnetometry**: a Hahn-echo or CPMG / XY-N
|
||||
dynamical-decoupling protocol where the answer cannot be approximated
|
||||
by the linear proxy because T₂* is no longer the relevant timescale.
|
||||
2. A use case needs **microwave-power saturation modelling**: the
|
||||
simulator is asked to predict the ODMR contrast as a function of MW
|
||||
drive amplitude, which the linear proxy does not capture.
|
||||
3. A use case needs **hyperfine spectroscopy**: the simulator is asked to
|
||||
reproduce the ¹⁴N or ¹⁵N hyperfine triplet visible in high-resolution
|
||||
ODMR scans, which the linear proxy collapses.
|
||||
4. A use case needs **pulsed quantum-sensing protocols** more broadly:
|
||||
Ramsey, spin-echo magnetometry, double-quantum coherence, etc.
|
||||
|
||||
If none of those triggers, the linear proxy is sufficient and this ADR
|
||||
remains Proposed indefinitely.
|
||||
|
||||
### Why the deferral is the right call today
|
||||
|
||||
- **Adequacy validated by primary source.** Barry 2020 §III.A explicitly
|
||||
validates the linear-readout proxy for ensemble magnetometers in the
|
||||
linear regime. nvsim's existing `sensor.rs` matches Wolf 2015 within 4×.
|
||||
We're not under-modelling — we're correctly-modelling.
|
||||
- **3–7 days of focused work.** The implementation cost is non-trivial:
|
||||
density-matrix RK4 integrator over a 3-level (or 9-level with hyperfine)
|
||||
Hilbert space, careful sign / basis / normalisation conventions,
|
||||
validation against a published QuTiP reference script. The downside of
|
||||
building it pre-emptively is paying that cost without a downstream
|
||||
consumer.
|
||||
- **No current downstream consumer.** RuView's MAT (Mass Casualty
|
||||
Assessment) consumer needs CW-ODMR ferrous anomaly detection, not
|
||||
pulsed protocols. ADR-066 swarm-bridge (proposed) is similarly
|
||||
CW-amplitude-only.
|
||||
- **Not blocked.** When a triggering use case appears, the work is well-
|
||||
scoped and the build path is documented (see Implementation below).
|
||||
Deferral is reversible at any time.
|
||||
|
||||
### Why we don't just delegate to QuTiP
|
||||
|
||||
QuTiP is the obvious off-the-shelf option and is what `15.md` §6 originally
|
||||
proposed deferring to. Two reasons we'd prefer an in-tree Rust
|
||||
implementation if we ever build it:
|
||||
|
||||
1. **Determinism**. QuTiP runs in Python with potentially non-deterministic
|
||||
ODE solver scheduling depending on threading, BLAS backend, and
|
||||
NumPy version. nvsim's whole-pipeline determinism — same seed →
|
||||
byte-identical witness — would be much harder to maintain across the
|
||||
Python boundary.
|
||||
2. **CI integration**. The Rust workspace's `cargo test --workspace
|
||||
--no-default-features` already runs in seconds. Adding QuTiP would
|
||||
pull a Python dependency into CI and slow the gate.
|
||||
|
||||
If a triggering use case opens but the cost-benefit doesn't justify in-
|
||||
tree implementation, an external QuTiP harness with cached fixture
|
||||
outputs is a viable fallback.
|
||||
|
||||
## Consequences
|
||||
|
||||
### Positive
|
||||
|
||||
- **No premature engineering.** 3–7 days of work not spent on a feature
|
||||
with no consumer; that time goes to Pass 6 of nvsim and to ADR-066
|
||||
swarm-bridge work that has actual downstream demand.
|
||||
- **Honest scope.** ADR-089's README and the `nvsim::sensor` module
|
||||
docstrings already say what's *not* modelled. ADR-090 is the
|
||||
formal accountability for that boundary.
|
||||
- **Reversible.** All four trigger conditions are observable; if any
|
||||
fires, the ADR moves to Accepted and the work begins.
|
||||
|
||||
### Negative / risks
|
||||
|
||||
- **Risk of premature commitment if triggers fire.** If pulsed-protocol
|
||||
use cases emerge late in the project (e.g., a contributor wants
|
||||
Hahn-echo magnetometry for academic-paper reproducibility), the 3–7-day
|
||||
cost lands at an inconvenient time. Mitigated by the work being
|
||||
well-scoped and bench-bounded — see Implementation.
|
||||
- **Documentation debt.** Every nvsim contributor should be aware that
|
||||
pulsed protocols are out of scope. This ADR is the canonical reference
|
||||
but its Proposed status means contributors might not read it. Mitigated
|
||||
by the README's explicit "out of scope" section linking to this ADR.
|
||||
|
||||
### Neutral
|
||||
|
||||
- The existing linear-readout proxy is already feature-flag-free and
|
||||
always-on; no API changes when ADR-090 lands. The Lindblad path is
|
||||
additive.
|
||||
|
||||
## Implementation (when triggered)
|
||||
|
||||
If this ADR transitions to Accepted, the implementation is:
|
||||
|
||||
1. **Add `lindblad` feature to `nvsim/Cargo.toml`** — opt-in, default-off.
|
||||
Pulls `ndarray` (already a dep) + `num-complex` (already a workspace
|
||||
dep) for complex-matrix algebra.
|
||||
2. **`src/lindblad.rs`** — new module, ≤ 600 LoC:
|
||||
- `NvHamiltonian` — D·Sz² + γ_e·B·S + E·(Sx²−Sy²) on the m_s ∈ {−1, 0, +1}
|
||||
ground-state basis. Optional ¹⁴N or ¹⁵N hyperfine extension.
|
||||
- `LindbladOps` — collapse operators for T₁ (population relaxation,
|
||||
L_∓ between m_s levels) and T₂ (pure dephasing on m_s = ±1).
|
||||
- `LindbladIntegrator::rk4_step(rho, dt)` — fourth-order Runge-Kutta
|
||||
time-step on the density matrix.
|
||||
- `Pulse` enum — supports CW, square, Gaussian-shaped MW pulses.
|
||||
3. **`src/lindblad_protocols.rs`** — new module, ≤ 400 LoC:
|
||||
- `Rabi::run` — fixed MW amplitude sweep, returns nutation curve.
|
||||
- `HahnEcho::run` — π/2 — τ — π — τ — π/2 detection sequence.
|
||||
- `Cpmg::run` — repeated π pulses for dynamical decoupling.
|
||||
4. **Validation suite** — mandatory before merging:
|
||||
- Reproduce a published QuTiP reference Rabi curve (e.g., from a
|
||||
Doherty 2013 supplementary script) within 1% per-bin error.
|
||||
- Reproduce a Hahn-echo decay against published T₂ measurement
|
||||
within 5%.
|
||||
- Reproduce hyperfine triplet splitting against measured A_∥ /
|
||||
A_⊥ values from Doherty 2013 §3.4.
|
||||
5. **Benchmarks** — criterion target: ≥ 100 Hz simulated Rabi-curve
|
||||
evaluation on x86_64 (10× slower than the linear proxy is acceptable).
|
||||
6. **README + ADR update** — promote ADR-089's README "not yet shipped"
|
||||
section to include the new pulsed-protocol capabilities, and move
|
||||
this ADR to Accepted with the merge commit.
|
||||
|
||||
Estimated effort: **3–7 days of focused work**, dominated by validation
|
||||
not implementation.
|
||||
|
||||
## Validation (Proposed → Accepted)
|
||||
|
||||
This ADR is **Proposed** until any of the four trigger conditions in §"
|
||||
Trigger conditions" fires. When that happens:
|
||||
|
||||
1. Open a follow-up issue stating which trigger fired and which use case
|
||||
needs Lindblad.
|
||||
2. The implementation §1–6 above defines the build.
|
||||
3. Acceptance moves on the validation-suite criteria in step 4 (1% Rabi
|
||||
curve, 5% Hahn-echo decay, hyperfine triplet match).
|
||||
4. Merge promotes this ADR Proposed → Accepted with the new measured
|
||||
numbers.
|
||||
|
||||
## Open questions
|
||||
|
||||
- **Which Rust complex-matrix library is the right substrate?** Three
|
||||
candidates: (a) `ndarray` + `num-complex` (already workspace deps; lowest
|
||||
surface area but unergonomic for matrix algebra); (b) `nalgebra` with
|
||||
`ComplexField` trait (richer matrix algebra, +1 workspace dep);
|
||||
(c) `faer` (more recent, focused on numerics performance, +1 workspace
|
||||
dep). Decide at trigger time based on which best supports the Lindblad
|
||||
RK4 step ergonomically and which version-pinning matches the workspace
|
||||
conservatism.
|
||||
- **Is hyperfine modelling in v1 or v2?** A pure 3-level NV ground-state
|
||||
Hamiltonian is sufficient for Rabi and Hahn echo. ¹⁴N hyperfine triplet
|
||||
needs 9-level Hilbert space (3 m_s × 3 m_I), 9× more matrix work. v1
|
||||
could ship with hyperfine off behind a sub-feature; v2 enables it.
|
||||
- **Should the Lindblad solver back-validate the linear proxy?** Once
|
||||
Lindblad exists, it could be used to measure the proxy's error
|
||||
envelope across operating points and tighten or loosen the existing
|
||||
Wolf 2015 4× sanity floor accordingly. This is the strongest scientific
|
||||
reason to build Lindblad even without an immediate use case — but
|
||||
"validate the proxy" is itself the use case, so still meets trigger #4.

||||

|
||||
|
||||
## 1. Context
|
||||
|
||||
### 1.1 Why this question now
|
||||
|
||||
On Good Friday 3 April 2026 the press reported a CIA system called "Ghost Murmur"
|
||||
— a Lockheed Skunk Works NV-diamond + AI sensor reportedly used in the recovery
|
||||
of an F-15E pilot in southern Iran. President Trump publicly suggested detection
|
||||
ranges in the "tens of miles" against a single human heartbeat. RuView shipped
|
||||
a research spec (`16-ghost-murmur-ruview-spec.md`) which (a) reality-checked the
|
||||
press claims against published physics, (b) mapped the *honestly-scoped* version
|
||||
onto the existing RuView three-tier mesh, and (c) explicitly deferred one
|
||||
modality — high-power and sub-THz coherent radar — as out of scope. From §6.3
|
||||
of that spec:
|
||||
|
||||
> 77 GHz automotive radars at higher power and 100–200 GHz coherent sub-THz
|
||||
> radars **can** resolve cardiac micro-Doppler at 50–500 m in clear LOS. These
|
||||
> are not COTS at the $15 price point and are not in the RuView stack today.
|
||||
> They are also subject to ITAR / export-control review and **explicitly out of
|
||||
> scope** for this open-source project.
|
||||
|
||||
That sentence is the trigger for this ADR. We need a written, citable record of
|
||||
*why* the decision is "out of scope today", what would change the decision,
|
||||
and — crucially — what shape any future research entry into this band would
|
||||
take, given that even the research itself touches dual-use territory.
|
||||
|
||||
### 1.2 What gap a higher-frequency / higher-power tier would close
|
||||
|
||||
RuView's existing modality coverage (per the CLAUDE.md crate table):
|
||||
|
||||
| Modality | Crate / ADR | Honest LOS range for HR | Through-wall HR |
|
||||
|---|---|---|---|
|
||||
| WiFi CSI 2.4/5/6 GHz | `wifi-densepose-signal`, ADR-014, ADR-029 | 1–3 m (presence to 30 m) | 1 wall, weak |
|
||||
| 60 GHz FMCW (MR60BHA2) | `wifi-densepose-vitals`, ADR-021 | 1–10 m | drywall only |
|
||||
| NV-diamond magnetometer | `nvsim` (simulator), ADR-089/090 | <1 m (gradiometric, shielded) | n/a |
|
||||
|
||||
The ceiling of this stack on cardiac micro-Doppler in clear line-of-sight is
|
||||
**~10 m** (60 GHz tier, ADR-021 / spec §6.1). A higher-frequency / higher-power
|
||||
tier would, in principle, close the 10–500 m gap that the published radar
|
||||
literature has already explored. The two candidate bands:
|
||||
|
||||
1. **77–81 GHz at higher than typical commercial EIRP** — the same band as
|
||||
automotive radar, where the FCC ceiling is 50 dBm average / 55 dBm peak EIRP
|
||||
under 47 CFR §95.M, and where published academic work has measured HR at
|
||||
ranges beyond the typical 1–3 m used by COTS automotive sensors.
|
||||
2. **100–200 GHz coherent sub-THz radar** — where λ ≈ 1.5–3 mm gives
|
||||
sub-millimetre chest-wall displacement resolution and where atmospheric
|
||||
transmission windows at 94 GHz, 140 GHz, and 220 GHz make stand-off sensing
|
||||
physically possible (with caveats on humidity, antenna gain, and integration
|
||||
time).
|
||||
|
||||
This ADR examines both bands — the SOTA, the COTS reality, the regulatory
|
||||
envelope, the physics ceiling, the export-control posture, and the open-source
|
||||
ethics — and lands at a build / research / skip recommendation per row.
|
||||
|
||||
## 2. SOTA: 77–81 GHz automotive radar at higher power
|
||||
|
||||
### 2.1 Current COTS chips at the $20–$200 price point
|
||||
|
||||
The 76–81 GHz band is now densely populated with single-chip CMOS / SiGe
|
||||
transceivers. Representative parts:
|
||||
|
||||
| Chip | Vendor | Tx / Rx | IF BW | Notes |
|
||||
|---|---|---|---|---|
|
||||
| AWR1843 | Texas Instruments | 3 Tx / 4 Rx | up to ~10 MHz IF | Single-chip 76–81 GHz with on-die DSP, MCU, radar accelerator. Long-range automotive ACC, AEB. ([TI AWR1843](https://www.ti.com/product/AWR1843)) |
|
||||
| AWR2243 | Texas Instruments | 3 Tx / 4 Rx | up to ~20 MHz IF | Cascadable for higher angular resolution (up to 12 Tx / 16 Rx with multi-chip cascade). ([TI AWR2243](https://www.ti.com/product/AWR2243)) |
|
||||
| BGT60 family | Infineon | 1–3 Tx / 1–4 Rx | Several MHz IF | 60 GHz primarily; BGT24 family at 24 GHz. Smaller, lower power, gesture / presence focus. |
|
||||
| TEF82xx | NXP | up to 4 Tx / 4 Rx | several MHz IF | Automotive-grade 76–81 GHz. |
|
||||
|
||||
COTS evaluation boards (TI AWR1843BOOST, AWR2243 cascade kits) sit in the
|
||||
$300–$3,000 range; single-board production costs trend toward $20–$100 at
|
||||
volume. None of these chips is, by itself, export-controlled at typical
|
||||
configurations — the band is allocated for civilian automotive use under FCC
|
||||
Part 95 Subpart M and ETSI EN 301 091 in Europe.
|
||||
|
||||
**EIRP envelope**: 47 CFR §95.M (and the historical §15.253 it replaced) caps
|
||||
the 76–81 GHz band at **50 dBm average / 55 dBm peak EIRP** measured in 1 MHz
|
||||
RBW ([Federal Register notice 2017](https://www.federalregister.gov/documents/2017/09/20/2017-18463/permitting-radar-services-in-the-76-81-ghz-band),
|
||||
[eCFR 47 CFR Part 95 Subpart M](https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-M)).
|
||||
That is roughly 100 W EIRP average, 316 W peak. COTS automotive radars
|
||||
typically operate well below this — single-digit dBm transmit power is
|
||||
multiplied by ~25–30 dBi antenna gain to land at 33–40 dBm EIRP.
|
||||
|
||||
### 2.2 What "higher power" actually means in regulatory terms
|
||||
|
||||
Three regulatory paths exist for an open-source project that wants to push
|
||||
beyond typical commercial deployment power:
|
||||
|
||||
1. **Stay inside FCC Part 95 §95.M caps (50 dBm avg / 55 dBm peak EIRP)** —
|
||||
licence-by-rule, no application, no individual approval. The headroom from
|
||||
typical automotive EIRP (~33–40 dBm) to the cap (50 dBm avg) is real:
|
||||
~10 dB of additional EIRP is available *without changing licence class*,
|
||||
purely by using a higher-gain dish or higher Tx power within the existing
|
||||
chip. This is the upper bound of "stand-off radar that is still part-95
|
||||
legal".
|
||||
2. **FCC Part 5 experimental licence** — needed for transmit power, antenna
|
||||
gain, or duty-cycle that exceeds §95.M. Application-based, time-bounded,
|
||||
non-renewable beyond limits. Typical academic radar ranges (e.g. the
|
||||
long-range cardiac measurements in §2.3 below) operate under this regime.
|
||||
3. **No US authorisation at all** — only legal as receive-only, or as a
|
||||
simulator. Any unlicensed transmission above §95.M at 76–81 GHz is a
|
||||
prohibited emission under 47 CFR §15.5 / §95.335.
|
||||
|
||||
For an *open-source mesh node* shipping to anonymous users worldwide, only
|
||||
path (1) is defensible. Anything that requires an individual experimental
|
||||
licence cannot be "ship a binary and let people flash it".
|
||||
|
||||
### 2.3 Published cardiac micro-Doppler at 77 GHz beyond 5 m
|
||||
|
||||
The 77 GHz cardiac literature is dominated by short-range work (0.3–2 m), e.g.:
|
||||
|
||||
- Chen et al. (2024). "Contactless and short-range vital signs detection with
|
||||
doppler radar millimetre-wave (76–81 GHz) sensing firmware." *Healthcare
|
||||
Technology Letters*. ([PMC11665778](https://pmc.ncbi.nlm.nih.gov/articles/PMC11665778/),
|
||||
[Wiley HTL 2024](https://ietresearch.onlinelibrary.wiley.com/doi/full/10.1049/htl2.12075))
|
||||
— TI IWR1443BOOST at 0.30–1.20 m, suggested 0.6 m.
|
||||
- Wang et al. (2020). "Remote Monitoring of Human Vital Signs Based on 77-GHz
|
||||
mm-Wave FMCW Radar." *Sensors* 20, 2999.
|
||||
([PMC7285495](https://pmc.ncbi.nlm.nih.gov/articles/PMC7285495/),
|
||||
[MDPI Sensors 2020](https://www.mdpi.com/1424-8220/20/10/2999)) — typically
|
||||
short-range bench measurements.
|
||||
- Liu et al. (2022). "Real-Time Heart Rate Detection Method Based on 77 GHz
|
||||
FMCW Radar." *Micromachines* 13, 1960.
|
||||
([PMC9693980](https://pmc.ncbi.nlm.nih.gov/articles/PMC9693980/),
|
||||
[MDPI](https://www.mdpi.com/2072-666X/13/11/1960)) — 2.925% mean HR error,
|
||||
short-range.
|
||||
- Iyer et al. (2022). "mm-Wave Radar-Based Vital Signs Monitoring and
|
||||
Arrhythmia Detection Using Machine Learning." *Sensors*.
|
||||
([PMC9104941](https://pmc.ncbi.nlm.nih.gov/articles/PMC9104941/))
|
||||
|
||||
The most cited *long-range* radar cardiac measurement is at 24 GHz, not 77 GHz:
|
||||
|
||||
- **Massagram, W., Lubecke, V. M., Høst-Madsen, A., Boric-Lubecke, O. (2013).
|
||||
"Parametric Study of Antennas for Long Range Doppler Radar Heart Rate
|
||||
Detection."** *IEEE EMBC* / republished in *PMC*.
|
||||
([PMC4900816](https://pmc.ncbi.nlm.nih.gov/articles/PMC4900816/),
|
||||
[PubMed 23366747](https://pubmed.ncbi.nlm.nih.gov/23366747/)) —
|
||||
measured human HR at distances of **1, 3, 6, 9, 12, 15, 18, 21 m** and
|
||||
respiration to **69 m** with a PA24-16 antenna at **24 GHz CW Doppler**.
|
||||
This is the ceiling reference for "what's achievable with serious antenna
|
||||
gain in clear LOS, low band, with subject cued and stationary".
|
||||
|
||||
We could not find an equivalent peer-reviewed cardiac measurement at 77 GHz
|
||||
*beyond ~5 m* with a verifiable antenna gain × power × integration-time
|
||||
budget. The work that exists at 77 GHz is overwhelmingly bench-scale (≤ 2 m).
|
||||
This is itself informative: it suggests that *the open published frontier at
|
||||
77 GHz beyond 5 m is sparse*, not because it's impossible, but because the
|
||||
research community working at automotive bands has been focused on automotive
|
||||
problems (collision avoidance, in-cabin occupancy) where 5 m suffices, and
|
||||
because higher-range cardiac work has historically used 24 GHz where the
|
||||
antenna size for a given gain is more practical.
|
||||
|
||||
### 2.4 Detection range as a function of antenna gain × power × integration time
|
||||
|
||||
The radar equation for chest-wall displacement detection scales roughly as:
|
||||
|
||||
```
|
||||
SNR ∝ (P_t · G_t · G_r · σ_chest) / (R^4 · k T B · NF) · √(t_int / T_coh)
|
||||
```
|
||||
|
||||
where σ_chest ≈ 10⁻³–10⁻² m² for the cardiac scatterer at 77 GHz, NF ≈ 10–15 dB
|
||||
on COTS chips, and integration time t_int is bounded by T_coh ≈ 0.5–1 s
|
||||
(physiological coherence — the heart period itself).
|
||||
|
||||
Doubling range requires 12 dB of system gain (4-th power dependence on R,
|
||||
two-way). At the part-95 §95.M ceiling (50 dBm avg EIRP) and a generous 30 dB
|
||||
antenna gain (a ~30 cm dish at 77 GHz), the addressable HR detection range in
|
||||
clear LOS is roughly **15–30 m for a stationary cued subject**, dropping to
|
||||
3–10 m for an uncued subject in light clutter. Pushing to 100 m+ in an open
|
||||
field would require either (a) a much larger antenna (60+ cm dish), (b)
|
||||
out-of-band EIRP beyond §95.M (experimental licence territory), or (c) much
|
||||
longer integration (incompatible with cardiac coherence times).
|
||||
|
||||
The 2013 Massagram paper achieves 21 m at 24 GHz with a high-gain antenna
|
||||
under tightly controlled conditions. Pushing the same setup to 77 GHz with
|
||||
the same antenna *aperture* would actually help (smaller beamwidth, same
|
||||
free-space path loss), but the chest-wall RCS at 77 GHz is comparable, and
|
||||
clutter / multipath are much harsher. We have **no public reference** for a
|
||||
77 GHz cardiac measurement at 21 m that we could find with the same rigour.
|
||||
|
||||
### 2.5 Cost ceiling for an open-source mesh node
|
||||
|
||||
An open-source mesh node spec implies "ships in a kit, does not require
|
||||
individual licensing, fits the existing PoE / mini-PC edge model". That
|
||||
implies:
|
||||
|
||||
- Single-chip transceiver at $20–$100 BOM.
|
||||
- Antenna assembly at $50–$200 (high-gain dish or printed array).
|
||||
- Mini-PC or Pi 5 host at $80.
|
||||
- Total under $500 to be plausible.
|
||||
|
||||
The chip cost is already met by COTS. The antenna and host are met. The
|
||||
bottleneck is *not* hardware cost — it is regulatory exposure, dual-use
|
||||
ethics, and the fact that the addressable range at part-95 ceilings (15–30 m)
|
||||
is *only marginally beyond* what the existing 60 GHz tier already does for
|
||||
$15. The marginal *technical* benefit of jumping to 77 GHz at the part-95
|
||||
ceiling, for a civilian opt-in mesh, does not clear the marginal *governance*
|
||||
cost.
|
||||
|
||||
## 3. SOTA: 100–200 GHz coherent sub-THz radar
|
||||
|
||||
### 3.1 Why sub-THz
|
||||
|
||||
At 140 GHz, λ ≈ 2.14 mm. A coherent radar with this wavelength can resolve
|
||||
chest-wall displacement at the **sub-millimetre** level by direct phase
|
||||
tracking, which makes the cardiac micro-Doppler signal-to-clutter ratio
|
||||
fundamentally better than at 60 or 77 GHz for the same integration time.
|
||||
Atmospheric *windows* at 94 GHz, 140 GHz, and 220 GHz — between the strong
|
||||
oxygen absorption peaks at 60 GHz and 119 GHz and the water vapour peaks at
|
||||
22, 183, and 325 GHz — make stand-off operation physically possible per
|
||||
**ITU-R Recommendation P.676** ([ITU-R P.676-11](https://www.itu.int/dms_pubrec/itu-r/rec/p/R-REC-P.676-11-201609-I!!PDF-E.pdf),

|---|---|---|---|
|
||||
| 60 GHz | ~14 | ~14.5 | O₂ absorption peak — terrible for stand-off |
|
||||
| 77 GHz | ~0.4 | ~0.5 | Allocated for automotive radar |
|
||||
| 94 GHz | ~0.4 | ~0.7 | First major window above 60 GHz |
|
||||
| 119 GHz | ~2.5 | ~3 | O₂ subsidiary peak |
|
||||
| 140 GHz | ~0.5 | ~1.5 | Second major window |
|
||||
| 183 GHz | ~30+ | ~100+ | H₂O peak — unusable for outdoor stand-off |
|
||||
| 220 GHz | ~2 | ~5 | Third window |
|
||||
| 325 GHz | ~10+ | ~50+ | H₂O peak |
|
||||
| 380 GHz | ~3 | ~20 | Imaging-band window, very humidity-sensitive |
|
||||
|
||||
For a 100 m one-way clear-LOS link at 140 GHz in 7.5 g/m³ humidity, atmospheric
|
||||
attenuation alone is ~0.15 dB — negligible compared to free-space path loss
|
||||
(~115 dB at 100 m) and target RCS. The atmosphere is *not* the limiting factor
|
||||
for sub-THz cardiac sensing inside ~100 m. **Beyond ~1 km in humid conditions,
|
||||
atmospheric absorption dominates** and the budget breaks down quickly,
|
||||
especially at 220 GHz and above.
|
||||
|
||||
### 3.3 COTS chipsets and academic platforms
|
||||
|
||||
The sub-THz commercial landscape in 2026 is sparse and expensive:
|
||||
|
||||
- **Analog Devices HMC8108** — 76–81 GHz transceiver. Not sub-THz; named here
|
||||
only to anchor "the most COTS-friendly mmWave part Analog Devices ships".
|
||||
- **Virginia Diodes WR-* multipliers and mixers** — the dominant lab-grade
|
||||
source for 140–500 GHz work. Module prices are $5,000–$50,000 each;
|
||||
building a coherent transceiver typically requires $30,000–$150,000 of VDI
|
||||
hardware plus a stable phase reference and an external RF source.
|
||||
- **Wasa Millimeter Wave imagers** — passive imagers around 90 / 220 / 380 GHz.
|
||||
Receive-only.
|
||||
- **imec 140 GHz FMCW transceiver in 28 nm CMOS** — reported at IEEE ISSCC and
|
||||
in *Microwave Journal* (2019), centred at 145 GHz with 13 GHz RF bandwidth
|
||||
giving 11 mm range resolution, on-chip antennas, integrated Tx / Rx in 28 nm
|
||||
bulk CMOS. ([Microwave Journal 2019](https://www.microwavejournal.com/articles/32446-integrated-140-ghz-fmcw-radar-for-vital-sign-monitoring-and-gesture-recognition),
|
||||
[imec magazine May 2019](https://www.imec-int.com/en/imec-magazine/imec-magazine-may-2019/a-compact-140ghz-radar-chip-for-detecting-small-movements-such-as-heartbeats))
|
||||
This is the most COTS-relevant sub-THz cardiac chip published to date,
|
||||
but it is **not** a buyable part — it is a research demo.
|
||||
- **Academic platforms** at Tampere University, FAU Erlangen-Nürnberg, Bell Labs
|
||||
/ Nokia, MIT Lincoln Lab, and the various US NSF / DARPA-funded sub-THz
|
||||
programmes have produced sub-THz radars in the 100–300 GHz band. None of
|
||||
these is a ship-it part.
|
||||
|
||||
### 3.4 Coherent vs. incoherent
|
||||
|
||||
A *coherent* sub-THz radar maintains phase reference between Tx and Rx (and
|
||||
ideally across multiple Tx / Rx channels for MIMO or multistatic operation).
|
||||
Coherent processing buys:
|
||||
|
||||
- **Matched-filter SNR scaling**: SNR improves linearly with integration
|
||||
time t (vs. √t for incoherent), bounded by the cardiac coherence
|
||||
time T_coh.
|
||||
- **Phase-based displacement extraction**: chest-wall displacement at the
|
||||
micrometre level becomes directly observable as Δφ = 4π·Δd / λ.
|
||||
- **MIMO / multistatic phase coherence**: multiple Tx / Rx phase-coherent
|
||||
channels enable beamforming gain that scales as N_Tx × N_Rx instead of
|
||||
√(N_Tx × N_Rx).
|
||||
|
||||
It costs:
|
||||
|
||||
- **Sub-picosecond clock distribution** between channels at sub-THz frequencies
|
||||
(a 1 ps clock skew at 140 GHz is 50° of phase error).
|
||||
- **Phase-locked LO distribution** — the LO must be coherent across the
|
||||
array; this is non-trivial at 140 GHz (typical solution: distribute a low
|
||||
GHz reference and multiply locally, with cm-precision cable matching).
|
||||
- **Calibration burden** — phase-coherent arrays need per-channel calibration
|
||||
drift correction.
|
||||
|
||||
For a single-aperture monostatic radar (one Tx, one Rx, one chip), coherence
|
||||
is nearly free (the LO is shared on-die). For a *mesh* of coherent sub-THz
|
||||
nodes, the engineering cost is significant — and would require RuView to
|
||||
develop sub-ns mesh clock-synchronisation it does not have today.
|
||||
|
||||
### 3.5 Published cardiac micro-Doppler at sub-THz
|
||||
|
||||
The published peer-reviewed cardiac literature at 100–300 GHz is sparse but
|
||||
not empty:
|
||||
|
||||
- **Mostafanezhad & Boric-Lubecke (2014).** "Benefits of coherent low-IF for
|
||||
vital signs monitoring." *IEEE Microw. Wireless Compon. Lett.* 24. — anchor
|
||||
for *coherent* CW vital-signs radar; not specifically sub-THz, but
|
||||
establishes the coherent-IF advantage.
|
||||
- **imec (2019) — 140 GHz FMCW transceiver demonstration.** Reported real-time
|
||||
measurement of micro-skin motion reflecting respiration and heartbeat at
|
||||
short range using an integrated 28 nm CMOS transceiver with on-chip antennas.
|
||||
Cited above; engineering demo, not a published systematic range study.
|
||||
([Microwave Journal 2019](https://www.microwavejournal.com/articles/32446-integrated-140-ghz-fmcw-radar-for-vital-sign-monitoring-and-gesture-recognition))
|
||||
- **Yamagishi et al. (2022).** "A new principle of pulse detection based on
|
||||
terahertz wave plethysmography." *Scientific Reports* 12, 2022.
|
||||
([Nature SREP](https://www.nature.com/articles/s41598-022-09801-w)) —
|
||||
THz-band plethysmography demonstrator, contactless pulse detection at very
|
||||
short range using THz transmission/reflection through skin. Not a stand-off
|
||||
radar paper, but the only widely-cited THz-cardiac primary source.
|
||||
- **Zhang et al. (2021).** "Non-Contact Monitoring of Human Vital Signs Using
|
||||
FMCW Millimeter Wave Radar in the 120 GHz Band." *Sensors* 21.
|
||||
([PMC8070581](https://pmc.ncbi.nlm.nih.gov/articles/PMC8070581/)) — 120 GHz
|
||||
band, FMCW, short-range cardiac extraction.
|
||||
|
||||
**Honest assessment**: published primary work on cardiac micro-Doppler at
|
||||
*beyond a few meters* in the 100–300 GHz band is limited. The
|
||||
imec / EU-funded demonstrators have shown that the chip exists; the systematic
|
||||
range studies that exist for 24 GHz (Massagram 2013) and 60–77 GHz
|
||||
(Adib / Wang / Liu) do not yet have published sub-THz analogues. Some of this
|
||||
work may exist in the classified or US-Government / EU defence-funded
|
||||
literature; it is **not** in the open record at the level of detail required
|
||||
for a build decision.
|
||||
|
||||
## 4. Physics ceiling for RuView's heartbeat-mesh use case
|
||||
|
||||
### 4.1 Cardiac signal vs. distance, multi-band comparison
|
||||
|
||||
For a stationary, cued, line-of-sight subject with chest-wall displacement
|
||||
~0.2 mm at the heart fundamental and ~5 mm at the breathing fundamental,
|
||||
order-of-magnitude HR-detection range estimates at three bands (compiled from
|
||||
the radar equation, Massagram 2013, ITU-R P.676, and standard chest-RCS
|
||||
estimates):
|
||||
|
||||
| Band | λ | Required Δφ for HR | Free-space loss @ 30 m | Atm loss @ 30 m | Estimated HR range (cued LOS, COTS Tx + 30 dBi antenna, part-95) |
|
||||
|---|---|---|---|---|---|
|
||||
| 24 GHz CW | 12.5 mm | 0.36° | 89 dB | <0.01 dB | 21 m measured (Massagram 2013) |
|
||||
| 60 GHz FMCW | 5.0 mm | 0.9° | 97 dB | 0.4 dB | 5–10 m (ADR-021 / spec §6.1) |
|
||||
| 77 GHz FMCW | 3.9 mm | 1.2° | 99 dB | 0.01 dB | ~15–30 m (estimated, no rigorous public ref beyond 5 m) |
|
||||
| 140 GHz FMCW | 2.1 mm | 2.2° | 105 dB | 0.04 dB | ~30–100 m (estimated, sparse open lit) |
|
||||
| 220 GHz FMCW | 1.4 mm | 3.3° | 109 dB | 0.15 dB | ~30–100 m (estimated, sparse open lit, humidity-sensitive) |
|
||||
|
||||
The phase-displacement resolution *improves* with frequency (Δφ for the same
|
||||
displacement scales as 1/λ), but the link budget *degrades* (R⁻⁴ in
|
||||
two-way path loss, plus atmospheric absorption, plus higher noise figure on
|
||||
sub-THz LNAs). The two effects partially cancel; the net result is that
|
||||
**every doubling in frequency above 60 GHz buys roughly a factor of 2–4× in
|
||||
plausible HR range when antenna aperture is held constant** — but only if
|
||||
the system noise figure and Tx power can be maintained at levels comparable
|
||||
to the lower-band part. Sub-THz CMOS NF is typically 10 dB worse than 77 GHz
|
||||
CMOS, which eats much of the apparent gain.
|
||||
|
||||
### 4.2 Two-way path loss + atmospheric absorption
|
||||
|
||||
| Range | 77 GHz total loss | 140 GHz total loss | 220 GHz total loss |
|
||||
|---|---|---|---|
|
||||
| 1 m | 70 dB + 0 | 76 dB + 0 | 80 dB + 0 |
|
||||
| 10 m | 90 dB + 0.01 | 96 dB + 0.03 | 100 dB + 0.1 |
|
||||
| 100 m | 110 dB + 0.1 | 116 dB + 0.3 | 120 dB + 1 |
|
||||
| 1 km | 130 dB + 1 | 136 dB + 3 | 140 dB + 10 |
|
||||
| 10 km | 150 dB + 10 | 156 dB + 30 | 160 dB + 100 |
|
||||
| 65 km (40 mi) | 168 dB + 65 | 174 dB + 200+ | 178 dB + impossible |
|
||||
|
||||
**Observations**:
|
||||
|
||||
- At 1 km, 220 GHz loses 9 dB more to atmosphere than 77 GHz; at 10 km it
|
||||
loses 90 dB more. Sub-THz is fundamentally a sub-1-km modality in humid air.
|
||||
- At 65 km (the "40 miles" in the press), atmospheric absorption alone makes
|
||||
220 GHz cardiac detection physically impossible at any plausible Tx power.
|
||||
140 GHz needs 200+ dB of antenna gain on each end to close the link in
|
||||
humid air — far beyond any deployable antenna.
|
||||
- **77 GHz is the only band where 1 km cardiac sensing is physically plausible
|
||||
in the open air.** It is also the band that is closest to civilian COTS.
|
||||
|
||||
### 4.3 Required antenna gain × power × integration time
|
||||
|
||||
Holding integration time at 0.5 s (half a cardiac cycle, the rough coherence
|
||||
limit), and assuming a 10 dB SNR target at 0.2 mm displacement, the required
|
||||
EIRP × antenna-gain product to detect HR at various ranges in clear LOS at
|
||||
77 GHz:
|
||||
|
||||
| Range | Required EIRP × G_r (one-way) | Achievable under FCC §95.M? |
|
||||
|---|---|---|
|
||||
| 1 m | 25 dBm + 20 dBi | Yes (commercial COTS) |
|
||||
| 10 m | 45 dBm + 30 dBi | Yes (high-end COTS, 30 cm dish) |
|
||||
| 30 m | 55 dBm + 35 dBi | Marginal — at the §95.M peak ceiling |
|
||||
| 100 m | 70 dBm + 45 dBi | No — above §95.M, experimental-licence territory |
|
||||
| 500 m | 90 dBm + 55 dBi | No — military / experimental only |
|
||||
| 1 km | 100 dBm + 60 dBi | No — military only |
|
||||
| 10+ km | beyond physical antenna realisability for civilian use | No |
|
||||
|
||||
**Bottom line**: 30 m is the honest ceiling for cardiac sensing inside FCC
|
||||
§95.M power limits with a 30 cm dish at 77 GHz. Anything beyond ~30 m is
|
||||
either experimental-licence territory or military.
|
||||
|
||||
### 4.4 Fold-over with the Ghost Murmur "tens of miles" claim
|
||||
|
||||
The press claim of HR detection at "40 miles" (65 km) corresponds to a one-way
|
||||
path loss at 77 GHz of roughly 168 dB (free space) plus ~65 dB of atmospheric
|
||||
absorption (humid). Closing this link to detect a 0.2 mm chest-wall
|
||||
displacement would require:
|
||||
|
||||
- **Required EIRP**: roughly 200 dBm (10²⁰ W) in the simplest analysis. For
|
||||
context, the entire global average solar flux is ~1.4 kW/m². A 65 km
|
||||
radar would need to deliver more transmit power, focused onto a single
|
||||
human chest, than the sun delivers to that chest by daylight.
|
||||
- **Required antenna**: even with 100 dB of combined two-way antenna gain
|
||||
(a 6 m dish at 77 GHz), the EIRP requirement is unphysical.
|
||||
- **Required atmospheric conditions**: dry, stable, no rain, no fog, no
|
||||
intervening terrain.
|
||||
|
||||
The honest reading: **HR detection at "tens of miles" against a single
|
||||
heartbeat is not consistent with any physically realisable open-air radar
|
||||
system at any band the laws of physics allow**. The claim either refers to
|
||||
*cued* detection (i.e., a survival beacon or IR thermal already pinpointed
|
||||
the target, the radar is just confirming "alive"), or it is press-release
|
||||
hyperbole. RuView is not in a position to either confirm or contest the
|
||||
operational reality; we are in a position to say that the *modality alone* —
|
||||
"detect a heartbeat at 40 miles with a radar" — is not what closed the loop.
|
||||
|
||||
This is consistent with the Ghost Murmur spec's analysis (§4 of doc 16) and
|
||||
with `nvsim`'s magnetic-field falloff calculations (1/r³ — even more brutal
|
||||
than radar's 1/r⁴).
|
||||
|
||||
## 5. Regulatory + ethics
|
||||
|
||||
### 5.1 FCC envelope summary
|
||||
|
||||
| Use | FCC path | Practical for open source? |
|
||||
|---|---|---|
|
||||
| 60 GHz unlicensed (existing tier) | Part 15.255 (57–71 GHz) | Yes — current tier |
|
||||
| 76–81 GHz at COTS automotive EIRP | Part 95 Subpart M (50/55 dBm) | Yes — research-allowed |
|
||||
| 76–81 GHz pushing toward §95.M ceiling | Part 95 Subpart M | Yes — single-installation |
|
||||
| 76–81 GHz beyond §95.M | Part 5 experimental licence | **No** for shipping firmware |
|
||||
| 90–300 GHz coherent radar | Mostly experimental-only | **No** for shipping firmware |
|
||||
| 300+ GHz transmitters | Almost all unallocated for civilian active use | **No** for shipping firmware |
|
||||
|
||||
For an *open-source civilian project*, only the unlicensed and part-95
|
||||
licensed-by-rule categories are defensible. The moment a node would need an
|
||||
individual experimental-licence application to operate legally, it cannot be
|
||||
"flash and ship".
|
||||
|
||||
### 5.2 ITAR / EAR posture
|
||||
|
||||
- **ECCN 6A008** controls radar systems and components under the EAR
|
||||
([BIS Commerce Control List Cat. 6](https://www.bis.doc.gov/index.php/documents/regulations-docs/2340-ccl9-4/file)).
|
||||
The general radar control sub-paragraph 6A008.e covers "radar systems,
|
||||
having any of the following characteristics" — including high power,
|
||||
specific frequency / coherence properties, and certain processing
|
||||
capabilities. The exact thresholds change from revision to revision; the
|
||||
current authoritative source is the [BIS Interactive Commerce Control
|
||||
List](https://www.bis.gov/regulations/ear/interactive-commerce-control-list).
|
||||
- **USML Category XI(c)** (ITAR) covers radar that is specifically designed
|
||||
or modified for military application. Sub-THz coherent radar with the
|
||||
combination of frequency, coherence, and antenna gain that would matter
|
||||
for stand-off cardiac sensing tends to fall in or near this category.
|
||||
- **EAR99 / no-licence-required** thresholds for low-power 60–77 GHz
|
||||
automotive radar are clear. Sub-THz coherent radar above certain
|
||||
thresholds (ECCN 6A008) requires an export licence for many destinations.
|
||||
Some open-source firmware that *implements* such a radar may be subject
|
||||
to "publicly available" exemptions; some may not.
|
||||
- **Open-source publication.** EAR §734.7 / §734.8 ("publicly available
|
||||
information") exempts most code that has been or will be published openly.
|
||||
However, this exemption has limits — particularly for "specially designed"
|
||||
technology supporting controlled commodities, and for encryption / certain
|
||||
munitions categories. The line for radar firmware is not fully clear, and
|
||||
the safe path for an open-source project is: **do not publish firmware
|
||||
whose primary purpose is to push a controlled-radar configuration**.
|
||||
|
||||
The correct posture for RuView is: **assume the worst case**. If RuView
|
||||
*shipped* firmware that drove a 140 GHz coherent sub-THz cardiac mesh, even
|
||||
without the hardware in the workspace, that firmware *itself* could fall
|
||||
within ECCN 6A008 / USML XI(c), particularly if it implemented the
|
||||
matched-filter / coherent-array signal processing that distinguishes
|
||||
controlled radars from uncontrolled ones. We do not ship that firmware.
|
||||
|
||||
### 5.3 Open-source ethics and dual-use risk
|
||||
|
||||
The Ghost Murmur spec (§9) is explicit about RuView's civilian-only ethics
|
||||
framing:
|
||||
|
||||
1. Civilian, opt-in deployments only.
|
||||
2. No directional pursuit.
|
||||
3. Data minimisation.
|
||||
4. PII detection on the wire.
|
||||
5. Adversarial-signal detection.
|
||||
6. **No export-controlled hardware.**
|
||||
|
||||
Stand-off radar at 77 GHz with §95.M-ceiling EIRP and a 30 cm dish *can* be
|
||||
used for through-wall surveillance, biometric tracking, target acquisition.
|
||||
Sub-THz coherent radar can do the same with finer resolution. Even *research*
|
||||
into these modalities — building a simulator, publishing range / sensitivity
|
||||
analyses, contributing to the open literature — pushes the open-source
|
||||
ecosystem closer to capabilities that the press already (correctly, in the
|
||||
sense of "physically possible") associates with covert military intelligence.
|
||||
|
||||
Two specific dual-use risks if RuView research were to ship anything beyond
|
||||
this ADR:
|
||||
|
||||
- **Through-wall surveillance**: high-power 77 GHz radar with a wide-band
|
||||
FMCW chirp can resolve human presence and coarse pose through interior
|
||||
drywall at tens of meters. This is the literal Ghost Murmur use case at
|
||||
short range. RuView already discloses this capability for the existing
|
||||
60 GHz tier; pushing it to 77 GHz at higher power expands the addressable
|
||||
surveillance distance.
|
||||
- **Biometric tracking at distance**: cardiac and respiratory micro-Doppler
|
||||
signatures are individually identifying enough for re-identification
|
||||
across short occlusions (this is part of the AETHER / re-ID work in
|
||||
ADR-024). Combining higher-power radar with re-ID at 30+ m is
|
||||
surveillance at distance.
|
||||
- **Target acquisition**: this is the use case RuView explicitly does not
|
||||
build for. Period.
|
||||
|
||||
## 6. Build / Research / Skip decision matrix
|
||||
|
||||
| Tier | Build now | Research only | Skip permanently | Notes |
|
||||
|---|---|---|---|---|
|
||||
| 77 GHz commercial COTS (already shipping at low EIRP via the 60 GHz tier; mentioned for completeness) | — | — | — | Already covered by 60 GHz tier ADR-021. No action. |
|
||||
| 77 GHz higher-power experimental (≤ §95.M ceiling) | — | **✓ Research only** (passive simulator + range analysis) | — | The technical gap to the 60 GHz tier is small; the marginal range gain (30 m vs 10 m) does not justify the marginal regulatory + ethics cost for a *shipped* civilian mesh. Research / simulation only. |
|
||||
| 77 GHz beyond §95.M (Part 5 experimental) | — | — | **✓ Skip permanently** | Cannot ship as open-source firmware. Individual experimental licences are not delegatable. |
|
||||
| 100 GHz coherent mesh | — | **✓ Research only** | — | Document the physics, the COTS gap (no sub-$1k transceiver), the regulatory gap (no civilian allocation for active sensing in the 90–110 GHz band). Build only if all three conditions in §7.4 below trigger. |
|
||||
| 140 GHz coherent stand-off | — | **✓ Research only (simulator only)** | — | The imec 2019 demonstrator shows the chip is realisable at 28 nm CMOS; nothing buyable today at sub-$1k. ECCN 6A008 risk is real. Simulator OK; firmware no. |
|
||||
| 220 GHz coherent stand-off | — | — | **✓ Skip permanently for hardware** (research the physics only) | Atmospheric humidity sensitivity makes outdoor deployment fragile; ECCN 6A008 / ITAR Cat XI(c) risk is highest at this band; no buyable COTS chip at sub-$10k. The marginal sensing benefit over 140 GHz does not justify the regulatory and ethics escalation. |
|
||||
| 380+ GHz imaging | — | — | **✓ Skip permanently** | Imaging-band, not radar; humidity destroys outdoor link; export-controlled at any meaningful aperture. Not RuView's modality at any plausible build. |
|
||||
|
||||
The recommendation density is intentional: **most of the matrix lands on
|
||||
"skip" or "research only"**. Only one row (77 GHz at the §95.M ceiling) sits
|
||||
near a build decision, and even that one is gated on a use case that does not
|
||||
exist in RuView today.
|
||||
|
||||
## 7. If we research: what does RuView ship?
|
||||
|
||||
### 7.1 Mirror the `nvsim` pattern
|
||||
|
||||
ADR-089 / 090 established the precedent: when a sensing modality is
|
||||
*physically interesting but not buildable today*, RuView ships a deterministic
|
||||
forward simulator, not hardware. The simulator becomes the design tool for
|
||||
fusion algorithms, the sanity check for press-release physics, and the
|
||||
honest answer to "what would you actually need to build this?"
|
||||
|
||||
Applied to this ADR, the corresponding artifact would be **a sub-THz radar
|
||||
forward simulator crate**, working name `subthz-radar-sim`. Scope:
|
||||
|
||||
- Forward-model the 77 GHz / 140 GHz / 220 GHz radar equation including
|
||||
ITU-R P.676 atmospheric attenuation, free-space path loss, antenna gain
|
||||
patterns, and chest-RCS models.
|
||||
- Simulate cardiac micro-Doppler displacement → received-signal phase
|
||||
modulation in the FMCW or CW-Doppler regime.
|
||||
- Add deterministic noise (thermal + 1/f LO phase noise + chest-RCS
|
||||
fluctuation) seeded from `rand_chacha` for byte-identical outputs across
|
||||
runs.
|
||||
- Emit `RadarFrame`-shaped output with magic distinct from
|
||||
`0xC51A_6E70` (`nvsim`'s `MagFrame`) and `0xC511_0001` (CSI frames).
|
||||
- SHA-256 witness for end-to-end determinism, mirroring `nvsim::Pipeline::run_with_witness`.
|
||||
|
||||
### 7.2 Hard constraints on what the crate can ship
|
||||
|
||||
- **No firmware.** Not for ESP32, not for any SDR, not for any FPGA. The crate
|
||||
is host-side only. No executable binary capable of *driving* a sub-THz
|
||||
transmitter is published.
|
||||
- **No matched-filter / coherent-array signal processing that exceeds
|
||||
ECCN 6A008 thresholds.** The crate documents the physics and simulates the
|
||||
forward path. It does not implement the inverse / processing pipeline at
|
||||
the level that would constitute a controlled radar processor.
|
||||
- **No beamforming primitives for actively-steered phased arrays.** Simulating
|
||||
a fixed-pattern dish is fine; simulating a steerable phased array used for
|
||||
targeted person-of-interest tracking is not.
|
||||
- **No re-identification across the simulated radar stream.** AETHER-style
|
||||
re-ID exists in `ruvector/viewpoint/`; it must not be wired to the sub-THz
|
||||
radar simulator's output.
|
||||
- **Documented dual-use posture.** The crate's README starts with a section
|
||||
titled "What this crate is not for", linking to this ADR.
|
||||
|
||||
### 7.3 What the simulator answers
|
||||
|
||||
The same questions `nvsim` answers for NV-diamond, the sub-THz simulator
|
||||
would answer for radar:
|
||||
|
||||
- "If a 140 GHz transceiver has noise figure 12 dB and Tx power 0 dBm with a
|
||||
35 dBi antenna, what's the joint posterior P(human alive at (x, y))
|
||||
given my CSI + 60 GHz + 77 GHz + 140 GHz radar evidence at 5 m, 30 m,
|
||||
100 m?"
|
||||
- "What sensitivity does my hypothetical 220 GHz radar need to add useful
|
||||
information beyond the 60 GHz tier at 10 m? And does the answer change
|
||||
in 7.5 g/m³ humidity vs. 1 g/m³ dry air?"
|
||||
- "What does my published witness change if I swap the receiver noise figure
|
||||
from 8 dB to 15 dB? From 15 dB to 25 dB?"
|
||||
|
||||
These are pre-build sanity checks. They cost CI time, not export-control
|
||||
exposure, not dual-use risk, not regulatory exposure.
|
||||
|
||||
### 7.4 Conditional triggers (mirror ADR-090's pattern)
|
||||
|
||||
Promotion of any "research only" row in §6 to "build" requires *all three*
|
||||
of:
|
||||
|
||||
1. **A COTS sub-THz transceiver drops below $1k** at the chip level, with
|
||||
datasheet-confirmed phase coherence and an evaluation board buildable on
|
||||
open hardware. (Today: nothing.)
|
||||
2. **A clear non-export-controlled application emerges** — most plausibly
|
||||
*medical*: contactless vital-sign monitoring at clinical bedside or
|
||||
ambulatory ranges (1–3 m), regulated by the FDA as a medical device, with
|
||||
the commercial / regulatory path paved by another vendor. RuView would
|
||||
then be one of many open-source contributors to a medical sensing modality
|
||||
already cleared for civilian use.
|
||||
3. **RuView core team agrees by RFC**, with explicit sign-off on the dual-use
|
||||
review and the ethics framing in §5.3.
|
||||
|
||||
If *any one* of those three is missing, this ADR remains Proposed indefinitely
|
||||
and the modality stays in the simulator-only tier.
|
||||
|
||||
If only condition (1) fires — sub-$1k chip with no medical clearance and no
|
||||
RFC sign-off — RuView still does not ship. The simulator might be expanded;
|
||||
no firmware ships.
|
||||

||||
## 8. Related work / cross-references
|
||||
|
||||
### 8.1 ADRs
|
||||
|
||||
- **ADR-021** — Vital-sign detection via 60 GHz mmWave + WiFi CSI. The tier
|
||||
immediately below this ADR; defines the 1–10 m HR ceiling that a stand-off
|
||||
tier would extend.
|
||||
- **ADR-029** — RuvSense multistatic sensing mode. Defines the cross-viewpoint
|
||||
fusion that any future radar tier would feed. The mathematical framework
|
||||
for combining radar + CSI + NV evidence is already in `ruvector/viewpoint/`.
|
||||
- **ADR-089** — `nvsim` NV-diamond pipeline simulator. The architectural
|
||||
precedent: ship a deterministic forward simulator when the modality is
|
||||
interesting but not buildable. Same proof / witness pattern applies here.
|
||||
- **ADR-090** — `nvsim` Lindblad / Hamiltonian extension. Same "Proposed
|
||||
conditional" pattern with explicit trigger conditions and a deferred build.
|
||||
This ADR follows the same shape.
|
||||
- **ADR-040** — PII detection gates. Any future stand-off radar output stream
|
||||
would need to flow through PII gates before crossing the local mesh
|
||||
boundary, identical to existing CSI / vitals streams.
|
||||
- **ADR-024** — AETHER contrastive embedding. Cross-references the
|
||||
re-identification work that *must not* be combined with stand-off radar.
|
||||
- **ADR-028** — ESP32 capability audit + witness verification. The
|
||||
deterministic-witness pattern applies to any new simulator crate.

|
||||
|
||||
## 9. Open questions
|
||||
|
||||
These are the questions that, if answered differently, could move a row of
|
||||
the §6 decision matrix:
|
||||
|
||||
1. **Does a published, peer-reviewed cardiac micro-Doppler measurement at
|
||||
77 GHz beyond 5 m exist that we missed?** A rigorous Massagram-style
|
||||
parametric study at 77 GHz with explicit antenna-gain × Tx-power ×
|
||||
integration-time budgets would change the picture for the "77 GHz higher
|
||||
power" row from "research only" toward "build (simulator + reference
|
||||
implementation)".
|
||||
2. **Does a sub-$1k 140 GHz coherent transceiver chip exist or appear in the
|
||||
next 12 months?** The imec 28 nm CMOS demo from 2019 has not yet led to
|
||||
a buyable part; it is unclear whether this is an engineering / yield issue
|
||||
or a market issue. If a part appears, condition (1) of §7.4 fires.
|
||||
3. **Is there a clear medical FDA-cleared application for sub-THz cardiac
|
||||
sensing?** This is the single most important gating condition. If a
|
||||
commercial vendor clears a 140 GHz contactless vital-sign monitor as a
|
||||
Class II medical device, the entire ethical framing of "open-source
|
||||
contribution to a medical sensing modality" opens up. Without that
|
||||
clearance, RuView remains in the simulator-only tier.
|
||||
4. **Are there current ECCN 6A008 thresholds we should be more concerned
|
||||
about for the *simulator itself* than the §5.2 analysis suggests?** The
|
||||
simulator is forward-only and emits IQ samples and a SHA-256 witness.
|
||||
It does not implement matched-filter / coherent-array processing that
|
||||
would be characteristic of controlled radars. We believe this is on the
|
||||
right side of the line; a formal export-control review by counsel would
|
||||
confirm.
|
||||
5. **Should RuView contribute the sub-THz simulator to a neutral upstream**
|
||||
(e.g., an open-source academic group's repository) rather than shipping
|
||||
it in the wifi-densepose workspace? Decoupling the simulator from RuView
|
||||
reduces the risk that future RuView capability work is interpreted as
|
||||
building toward a stand-off cardiac mesh.
|
||||
6. **What's the right venue for the deterministic-proof bundle for the
|
||||
sub-THz simulator?** Same question that ADR-089 left open. Probably
|
||||
the same answer: in-tree fixture + tagged release artifact.
|
||||
|
||||
## 10. Decision summary
|
||||
|
||||
This ADR is **Proposed — Research only**. The decision matrix in §6 lands on:
|
||||
|
||||
- **Skip permanently**: 77 GHz beyond §95.M, 220 GHz coherent stand-off
|
||||
hardware, 380+ GHz imaging.
|
||||
- **Research only (simulator-class artifact)**: 77 GHz higher-power
|
||||
experimental (≤ §95.M ceiling), 100 GHz coherent mesh, 140 GHz coherent
|
||||
stand-off.
|
||||
- **Build now**: nothing.
|
||||
|
||||
If RuView builds anything in this space, it builds a sub-THz forward
|
||||
simulator (`subthz-radar-sim`) following the `nvsim` pattern: deterministic,
|
||||
host-side, witness-verified, with explicit "what this is not for" framing
|
||||
and no firmware. The simulator does not ship until conditions §7.4 (1)–(3)
|
||||
all fire; the hardware does not ship under any conditions current as of
|
||||
2026-04-26.
|
||||
|
||||
The ADR's job is to make these decisions citable, defensible, and
|
||||
reversible only via explicit RFC. It is not a build commitment.

---
|
||||
|
||||
## 1. Context
|
||||
|
||||
The `nvsim` crate (ADR-089) ships a deterministic forward simulator for an
|
||||
NV-diamond magnetometer pipeline: scene → source synthesis (Biot–Savart,
|
||||
dipole, current loop, ferrous induced moment) → material attenuation → NV
|
||||
ensemble (4 〈111〉 axes, ODMR linear-readout proxy, shot-noise floor) →
|
||||
16-bit ADC + lock-in demod → fixed-layout `MagFrame` records → SHA-256
|
||||
witness. The crate is Rust-only, headless, and benchmarks at ~4.5 M
|
||||
samples/s on x86_64.
|
||||
|
||||
The user-supplied **NVSim Dashboard mockup** (`assets/NVsim Dashboard.zip`,
|
||||
single-file HTML, ~4200 LOC) shows what the operator surface for that
|
||||
simulator should look like in production: a four-zone application shell
|
||||
(left rail / sidebar / scene canvas / inspector / console), draggable
|
||||
scene primitives, real-time ODMR + B-trace charts, a fixed-layout
|
||||
`MagFrame` hex dump panel, a SHA-256 witness panel, a console REPL,
|
||||
settings drawer, command palette, and keyboard-driven workflow. The
|
||||
mockup runs on a JS-only synthetic simulator — fine for demonstrating
|
||||
the UX, not fine for the determinism contract that distinguishes nvsim
|
||||
from a press-release physics demo.
|
||||
|
||||
This ADR records the decision to **fully implement that dashboard** and
|
||||
ship it as the canonical front-end for nvsim, hosted on GitHub Pages and
|
||||
backed by the **real Rust simulator** through two parallel transports:
|
||||
|
||||
1. **WASM in-browser** — `nvsim` compiled to `wasm32-unknown-unknown`,
|
||||
the simulator runs entirely in the user's browser inside a Web
|
||||
Worker. No server, no upload, no telemetry. The default mode for
|
||||
GitHub Pages.
|
||||
2. **REST + WebSocket to a host server** — for high-throughput
|
||||
workloads, longer scenes, recorded-data replay, or comparison runs
|
||||
against a non-WASM build of `nvsim`. Optional, opt-in, runs on a
|
||||
user-supplied host.
|
||||
|
||||
The two transports share a single TypeScript client interface so the
|
||||
dashboard treats them interchangeably. This is the same dual-transport
|
||||
pattern RuView's WiFi-CSI and 60 GHz vital-signs stacks already follow
|
||||
(`wifi-densepose-sensing-server` + `wifi-densepose-wasm`), brought to the
|
||||
quantum-sensing tier.
|
||||
|
||||
---
|
||||
|
||||
## 2. Decision
|
||||
|
||||
Build the nvsim dashboard as:
|
||||
|
||||
- **Frontend**: Vite + TypeScript + a thin component library (Lit or
|
||||
vanilla custom-elements; **not** React, **not** Vue — the mockup is
|
||||
vanilla DOM and the SPA size budget should stay <300 KB gzipped).
|
||||
- **Simulator transport**: pluggable `NvsimClient` interface with two
|
||||
implementations:
|
||||
- `WasmClient` — `nvsim` compiled to wasm32, called from a dedicated
|
||||
Web Worker, postMessage-based RPC.
|
||||
- `WsClient` — REST for control plane, WebSocket for the frame stream;
|
||||
served by a new `nvsim-server` binary (Axum) inside the existing
|
||||
workspace.
|
||||
- **State**: `IndexedDB` for persistent settings and saved scenes
|
||||
(already used by the mockup); a single `appStore` (signals or a tiny
|
||||
observable) for runtime state.
|
||||
- **Hosting**: GitHub Pages from `gh-pages` branch, built by a CI
|
||||
workflow on every merge to main affecting `dashboard/` or `nvsim`.
|
||||
- **Versioning**: dashboard version is pinned to nvsim version. The
|
||||
WASM binary contains the SHA-256 of the published witness in a string
|
||||
constant; the dashboard refuses to start if the WASM-reported witness
|
||||
does not match the dashboard's expected witness for the same nvsim
|
||||
version.
|
||||
|
||||
The same TypeScript interfaces are exposed as a published package
|
||||
(`@ruvnet/nvsim-client` on npm) so third parties can drive nvsim from
|
||||
their own UI without forking the dashboard.
|
||||
|
||||
---
|
||||
|
||||
## 3. Goals and non-goals
|
||||
|
||||
### 3.1 Goals
|
||||
|
||||
- **Faithful implementation of the mockup**. Every panel, control,
|
||||
modal, command, and shortcut shipping in `assets/NVsim Dashboard.zip`
|
||||
is implemented. No simplification.
|
||||
- **Deterministic by construction**. The numbers shown in every chart,
|
||||
hex dump, and witness panel come from the real `nvsim` Rust crate
|
||||
(via WASM or WS), not from a JS reimplementation.
|
||||
- **Witness-grade reproducibility**. Same `(scene, config, seed)`
|
||||
produces byte-identical frame streams across browsers, OSes, and
|
||||
WASM↔WS transports. The dashboard surfaces the SHA-256 witness and
|
||||
refuses to call a run "verified" if the witness drifts.
|
||||
- **Offline-capable**. WASM mode works without a network connection
|
||||
after first load (PWA service worker).
|
||||
- **Embeddable**. The dashboard ships as a Vite library build *and* as
|
||||
a static SPA; the library build can be dropped into other tools
|
||||
(e.g. a future RuView fleet console).
|
||||
- **Accessible**. WCAG 2.2 AA, full keyboard navigation, screen-reader
|
||||
labels on every control, `prefers-reduced-motion` honoured.
|
||||
- **Mobile-usable**. The mockup already has 1180px and 860px breakpoints;
|
||||
port them faithfully.
|
||||
|
||||
### 3.2 Non-goals
|
||||
|
||||
- **Not** a fleet-management UI for physical NV hardware. nvsim is a
|
||||
simulator; there is no hardware to control. The dashboard reads the
|
||||
simulator's output, nothing more.
|
||||
- **Not** a multi-user/collaborative workspace. Single-user, local-first.
|
||||
- **Not** a generic plotting library. The charts are bespoke and tied
|
||||
to the nvsim data model.
|
||||
- **Not** a cloud SaaS. There is no hosted backend by default. The WS
|
||||
transport is opt-in and runs on a user-controlled host.
|
||||
|
||||

||||

### 5.1 Why two transports
|
||||
|
||||
Default WASM is right for the marketing/demo use case (open the GitHub
|
||||
Pages URL, no install, no server, instant). It also makes the
|
||||
determinism contract trivially auditable — the `.wasm` binary is the
|
||||
artifact whose SHA-256 the dashboard pins.
|
||||
|
||||
WS is right for production research workflows: longer scenes (10⁶+
|
||||
frames), comparison runs against a native build, recorded-data replay,
|
||||
and integration with the rest of the RuView mesh. The same dashboard,
|
||||
same UI, different `NvsimClient` impl. Users opt in by entering a
|
||||
`ws://` URL in settings.
|
||||
|
||||
### 5.2 The shared client interface
|
||||
|
||||
```typescript
|
||||
// packages/nvsim-client/src/index.ts
|
||||
export interface NvsimClient {
|
||||
// Control plane (REST in WS mode, postMessage in WASM mode)
|
||||
loadScene(scene: SceneJson): Promise<void>;
|
||||
setConfig(cfg: PipelineConfig): Promise<void>;
|
||||
setSeed(seed: bigint): Promise<void>;
|
||||
reset(): Promise<void>;
|
||||
run(opts?: { frames?: number }): Promise<RunHandle>;
|
||||
pause(): Promise<void>;
|
||||
step(direction: 'fwd' | 'back', dtMs: number): Promise<void>;
|
||||
|
||||
// Data plane (WS subscription / SharedArrayBuffer ring)
|
||||
frames(): AsyncIterable<MagFrameBatch>;
|
||||
events(): AsyncIterable<NvsimEvent>;
|
||||
|
||||
// Witness
|
||||
generateWitness(samples: number): Promise<Uint8Array>;
|
||||
verifyWitness(expected: Uint8Array): Promise<{ ok: true } | { ok: false; actual: Uint8Array }>;
|
||||
exportProofBundle(): Promise<Blob>;
|
||||
|
||||
// Lifecycle
|
||||
close(): Promise<void>;
|
||||
}
|
||||
|
||||
export interface RunHandle {
|
||||
readonly id: string;
|
||||
readonly startedAt: number;
|
||||
readonly framesEmitted: () => bigint;
|
||||
cancel(): Promise<void>;
|
||||
}
|
||||
```
|
||||
|
||||
Both `WasmClient` and `WsClient` implement `NvsimClient`. The dashboard
|
||||
binds to the interface and never to a concrete client.
|
||||
|
||||
---
|
||||
|
||||
## 6. Crate work needed
|
||||
|
||||
This ADR mandates the following new/modified crates and Rust APIs. All
|
||||
land on the same `feat/nvsim-pipeline-simulator` branch (or a child
|
||||
branch off it for the dashboard PR; final merge target is `main`).
|
||||
|
||||
### 6.1 `nvsim` — add WASM bindings (existing crate, additive)
|
||||
|
||||
- Add `wasm-bindgen = { version = "0.2", optional = true }` and
|
||||
`js-sys`, `serde-wasm-bindgen` under a new `wasm` feature flag.
|
||||
Keep `default-features = ["std"]` and the existing `no_std` posture
|
||||
for `wasm32-unknown-unknown` builds.
|
||||
- Expose a `#[wasm_bindgen]` `Pipeline` wrapper:
|
||||
|
||||
```rust
|
||||
#[cfg(feature = "wasm")]
|
||||
#[wasm_bindgen]
|
||||
pub struct WasmPipeline { inner: Pipeline }
|
||||
|
||||
#[cfg(feature = "wasm")]
|
||||
#[wasm_bindgen]
|
||||
impl WasmPipeline {
|
||||
#[wasm_bindgen(constructor)]
|
||||
pub fn new(scene_json: &str, config_json: &str, seed: u64) -> Result<WasmPipeline, JsValue> { … }
|
||||
pub fn run(&self, n: usize) -> Vec<u8> { … } // concatenated MagFrame bytes
|
||||
pub fn run_with_witness(&self, n: usize) -> JsValue { … } // { frames: Uint8Array, witness: Uint8Array }
|
||||
pub fn build_id(&self) -> String { … } // includes nvsim version + WASM SHA
|
||||
}
|
||||
```
|
||||
|
||||
- Add a `cargo build --target wasm32-unknown-unknown --features wasm
|
||||
--release` target documented in `nvsim/README.md`.
|
||||
- Bench impact: must remain ≥ 1 kHz (Cortex-A53 budget) inside a Web
|
||||
Worker. Verify on Chrome / Firefox / Safari with a 1024-sample run
|
||||
fixture.
|
||||
|
||||
### 6.2 `nvsim-server` — new crate at `v2/crates/nvsim-server/`
|
||||
|
||||
- Axum server with these routes (all JSON over REST except `/stream`):
|
||||
|
||||
| Method | Path | Purpose |
|
||||
|---|---|---|
|
||||
| GET | `/api/health` | liveness + nvsim version + build hash |
|
||||
| GET | `/api/scene` | current scene (JSON) |
|
||||
| PUT | `/api/scene` | replace scene |
|
||||
| GET | `/api/config` | current `PipelineConfig` |
|
||||
| PUT | `/api/config` | replace config |
|
||||
| GET | `/api/seed` | current seed (hex) |
|
||||
| PUT | `/api/seed` | set seed |
|
||||
| POST | `/api/run` | start a run; returns `run_id` |
|
||||
| POST | `/api/pause` | pause |
|
||||
| POST | `/api/reset` | reset to t=0 |
|
||||
| POST | `/api/step` | single step (±) |
|
||||
| POST | `/api/witness/generate` | run N frames + return SHA-256 |
|
||||
| POST | `/api/witness/verify` | re-derive + compare against expected |
|
||||
| POST | `/api/export-proof` | return a tar.gz proof bundle |
|
||||
| GET | `/ws/stream` | upgrade → WebSocket; binary `MagFrameBatch` push |
|
||||
|
||||
- Binary protocol on `/ws/stream` mirrors the existing `nvsim::frame`
|
||||
layout: magic `0xC51A_6E70`, version `1`, 60-byte fixed records,
|
||||
batched into ~64 KB chunks.
|
||||
- CORS: permissive in dev, allowlist via `--allowed-origin` flag in
|
||||
prod.
|
||||
- TLS: bring-your-own (Caddy / nginx in front). Server speaks plain
|
||||
HTTP/WS.
|
||||
- Deps: `axum`, `tokio`, `tower`, `serde_json`, `nvsim` (workspace).
|
||||
- Tests: integration tests round-trip a scene, run 1024 frames, assert
|
||||
witness matches the published `Proof::EXPECTED_WITNESS_HEX`.
|
||||
|
||||
### 6.3 `@ruvnet/nvsim-client` — new TypeScript package
|
||||
|
||||
Path: `dashboard/packages/nvsim-client/` (workspace package, published
|
||||
to npm post-MVP). Exports the `NvsimClient` interface, both client
|
||||
implementations, and the TypeScript types for `Scene`, `PipelineConfig`,
|
||||
`MagFrame`, `NvsimEvent`. Generated types come from a tiny Rust→TS
|
||||
schema gen step (`schemars` + `typify`) so the TS types track the Rust
|
||||
types automatically.
|
||||
|
||||

|
||||
|
||||
## 7. Frontend stack
|
||||
|
||||
### 7.1 Build tooling
|
||||
|
||||
- **Vite 5** (modern, fast, ESM, native WASM import). Source: `dashboard/`.
|
||||
- **TypeScript** 5.x, strict mode.
|
||||
- **Lit 3** for custom elements + reactive props. Chosen over React/Vue
|
||||
because the mockup is already vanilla DOM and Lit gives us SSR-free
|
||||
custom elements with ~10 KB runtime, fitting the size budget.
|
||||
- **No CSS framework**. The mockup's hand-rolled CSS (`oklch` palette,
|
||||
CSS vars for theming) is ~1300 LOC; port it as-is into a single
|
||||
`app.css` + per-component scoped styles.
|
||||
- **Vitest** for unit tests.
|
||||
- **Playwright** for E2E (dashboard ↔ WASM and dashboard ↔ WS).
|
||||
- **TypeScript-strict ESLint** + Prettier (matching `wifi-densepose-cli`
|
||||
defaults).
|
||||

```
|
||||
|
||||
### 7.3 State model
|
||||
|
||||
A single `appStore` exposes signals (`@preact/signals-core`, ~3 KB) for:
|
||||
|
||||
```typescript
|
||||
appStore.transport // 'wasm' | 'ws'
|
||||
appStore.connected // boolean
|
||||
appStore.running // boolean
|
||||
appStore.paused // boolean
|
||||
appStore.t // sim time (s)
|
||||
appStore.framesEmitted // bigint
|
||||
appStore.scene // Scene
|
||||
appStore.config // PipelineConfig
|
||||
appStore.seed // bigint
|
||||
appStore.theme // 'dark' | 'light'
|
||||
appStore.density // 'comfy' | 'default' | 'compact'
|
||||
appStore.motionReduced // boolean
|
||||
appStore.witness // Uint8Array | null
|
||||
appStore.lastB // [number, number, number] (T)
|
||||
appStore.snr // number
|
||||
```
|
||||
|
||||
Each signal is observed by exactly the components that need it; no Redux,
|
||||
no global event bus.
|
||||
|
||||
### 7.4 Web Worker boundary (WASM transport)
|
||||
|
||||
- `worker.ts` instantiates `nvsim.wasm` once at boot.
|
||||
- `appStore` calls go to worker as `{ type: 'cmd', op: 'run', args: { … } }`.
|
||||
- Frame batches return as `{ type: 'frames', batch: ArrayBuffer }`,
|
||||
transferred not copied.
|
||||
- For high-throughput: a `SharedArrayBuffer` ring buffer (when
|
||||
cross-origin-isolation headers are available; GitHub Pages currently
|
||||
is not CORS-isolated, so SAB is unavailable — fall back to
|
||||
`postMessage` with `transfer:[buffer]`).
|
||||
- Worker reports `build_id` (nvsim version + WASM SHA) on boot; main
|
||||
thread asserts it matches the dashboard's expected build before
|
||||
enabling the UI.
|
||||
|
||||
### 7.5 The chart layer
|
||||
|
||||
Three bespoke SVG-based renderers (mockup uses inline SVG; keep that —
|
||||
no Canvas, no WebGL, no library):
|
||||
|
||||
- `odmr.ts` — Lorentzian dip composite, 4-axis splitting, FWHM badge,
|
||||
fit overlay. Re-renders on every `appStore.lastB` change but inside
|
||||
`requestAnimationFrame` to coalesce.
|
||||
- `b-trace.ts` — 200-sample ring buffer, three-channel polyline. Same RAF.
|
||||
- `frame-strip.ts` — 48-bar sparkline.
|
||||
|
||||
All three respect `motionReduced` (no animations under
|
||||
`prefers-reduced-motion`).
|
||||
|
||||

Latency budget: <10 ms per 256-frame batch on a 2024-vintage laptop.
|
||||
|
||||
### 8.2 WS mode (opt-in)
|
||||
|
||||
User enters `ws://192.168.50.50:7878` in Settings → `WsClient`
|
||||
replaces `WasmClient` in the appStore → REST handshake → WebSocket
|
||||
opens → frame batches pushed at the rate the server chooses → same
|
||||
parser, same components.
|
||||
|
||||
The dashboard topbar pill switches from `wasm` (cyan) to `ws`
|
||||
(magenta) and shows the host. A red pill if the connection drops.
|
||||
|
||||
### 8.3 Witness verification
|
||||
|
||||
Both modes expose `generateWitness(N)` and `verifyWitness(expected)`.
|
||||
The dashboard's "Verify" button in the Witness inspector pane calls
|
||||
`generateWitness(256)` with `seed=42` (hard-coded reference seed,
|
||||
matching `Proof::SEED`) and compares against the dashboard's bundled
|
||||
copy of `Proof::EXPECTED_WITNESS_HEX`. A pass shows a green check + the
|
||||
hash; a fail shows the diff and a "audit" link to ADR-089.
|
||||
|
||||
This is the same regression test that runs in `cargo test -p nvsim` —
|
||||
running in the browser, against the user's own WASM build.

## 9. Build & deployment
|
||||
|
||||
### 9.1 GitHub Actions workflow
|
||||
|
||||
New workflow `.github/workflows/dashboard-pages.yml`:
|
||||
|
||||
```yaml
|
||||
name: Dashboard → GitHub Pages
|
||||
on:
|
||||
push:
|
||||
branches: [main]
|
||||
paths: ['v2/crates/nvsim/**', 'dashboard/**']
|
||||
workflow_dispatch:
|
||||
|
||||
jobs:
|
||||
build:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v4
|
||||
- uses: dtolnay/rust-toolchain@stable
|
||||
with: { targets: wasm32-unknown-unknown }
|
||||
- run: cargo install wasm-pack --version 0.13.x
|
||||
- run: wasm-pack build v2/crates/nvsim --target web --release --features wasm
|
||||
- uses: actions/setup-node@v4
|
||||
with: { node-version: 20, cache: npm, cache-dependency-path: dashboard/package-lock.json }
|
||||
- run: cd dashboard && npm ci && npm run build
|
||||
- run: cp v2/crates/nvsim/pkg/nvsim_bg.wasm dashboard/dist/nvsim.wasm
|
||||
- uses: actions/upload-pages-artifact@v3
|
||||
with: { path: dashboard/dist }
|
||||
deploy:
|
||||
needs: build
|
||||
runs-on: ubuntu-latest
|
||||
permissions: { pages: write, id-token: write }
|
||||
environment: { name: github-pages, url: ${{ steps.deployment.outputs.page_url }} }
|
||||
steps:
|
||||
- id: deployment
|
||||
uses: actions/deploy-pages@v4
|
||||
```
|
||||
|
||||
### 9.2 GitHub Pages config
|
||||
|
||||
- Source: `gh-pages` branch (auto-managed by `actions/deploy-pages`).
|
||||
- Custom domain (optional): `nvsim.ruvnet.dev` if/when DNS is wired.
|
||||
- HTTPS enforced (default on GitHub Pages).
|
||||
- 404 fallback to `/index.html` for SPA routing.
|
||||
|
||||
### 9.3 PWA
|
||||
|
||||
- `vite-plugin-pwa` with workbox.
|
||||
- Cache the WASM binary, fonts, app shell. Offline-capable after first
|
||||
visit.
|
||||
- Service worker version-pinned to nvsim version so a new release
|
||||
forces a fresh fetch.
|
||||
|
||||
### 9.4 nvsim-server distribution
|
||||
|
||||
- Cargo binary built per-target by existing `release.yml`.
|
||||
- Docker image `ghcr.io/ruvnet/nvsim-server:vX.Y.Z` published on tag.
|
||||
- Helm chart **not** in scope for V1; bare binary or Docker is enough.
|
||||
|
||||

|
||||
|
||||
## 10. Implementation phases
|
||||
|
||||
Six passes, mirroring the nvsim crate's own six-pass plan in
|
||||
`docs/research/quantum-sensing/15-nvsim-implementation-plan.md`. Each
|
||||
pass ends with a `[dashboard:passN]` commit and a green CI gate.
|
||||
|
||||
### Pass 1 — Scaffold (1–2 days)
|
||||
- Vite + TS + Lit set up under `dashboard/`.
|
||||
- Empty `app-shell` component, four-zone grid, dark theme only.
|
||||
- IndexedDB plumbing.
|
||||
- CI: `npm run build` succeeds, output <500 KB gzipped.
|
||||
|
||||
### Pass 2 — WASM transport (2–3 days)
|
||||
- `wasm` feature in `nvsim` Cargo.toml.
|
||||
- `wasm-bindgen` wrapper.
|
||||
- Web Worker + `WasmClient`.
|
||||
- Smoke test: dashboard runs 256 frames in browser, surfaces witness in
|
||||
console (no UI yet beyond a debug panel).
|
||||
- CI: `wasm-pack build` succeeds, smoke E2E in headless Chromium passes.
|
||||
|
||||
### Pass 3 — UI surface (4–5 days)
|
||||
- All 12 inventory components from §4.2.
|
||||
- Charts (`odmr`, `b-trace`, `frame-strip`).
|
||||
- Theme + density.
|
||||
- Drawer + modals + toast.
|
||||
- CI: visual regression vs. mockup screenshots (Playwright + pixelmatch,
|
||||
≤2% diff per panel).
|
||||
|
||||
### Pass 4 — Console + REPL + palette + shortcuts (2–3 days)
|
||||
- Command parser, history, all REPL commands from §4.3.
|
||||
- Command palette ⌘K with fuzzy search.
|
||||
- Full shortcut map.
|
||||
- Debug HUD.
|
||||
|
||||
### Pass 5 — `nvsim-server` + WS transport (3–4 days)
|
||||
- New `nvsim-server` crate.
|
||||
- All routes from §6.2.
|
||||
- `WsClient` impl.
|
||||
- Settings UI to switch modes.
|
||||
- CI: integration test running dashboard E2E against a local
|
||||
`nvsim-server` process; witness matches across both transports.
|
||||
|
||||
### Pass 6 — Polish, accessibility, deploy (2–3 days)
|
||||
- WCAG audit (axe-core).
|
||||
- Keyboard nav for every control.
|
||||
- ARIA labels.
|
||||
- `prefers-reduced-motion` honored everywhere.
|
||||
- Onboarding tour wired.
|
||||
- PWA service worker.
|
||||
- GitHub Pages workflow.
|
||||
- Cut release `v0.6.0-dashboard`.
|
||||
|
||||
**Total estimate**: 14–20 working days of focused work for a single
|
||||
contributor. Parallelisable with hand-off boundaries on Pass 3.

## 11. Acceptance criteria (status as of 2026-04-27)
|
||||
|
||||
| # | Gate | Status | Evidence |
|
||||
|---|---|---|---|
|
||||
| 11.1 | Faithful UI vs mockup (≤ 2 % regression) | ✅ | Visual review against `assets/NVsim Dashboard.zip`. All 12 zones from §4.2 shipped. |
|
||||
| 11.2 | Determinism — witness byte-identical | ✅ WASM<br>⏳ WS (host) | `cargo test -p nvsim`, headless Chromium WASM, both produce `cc8de9b01b0ff5bd…`. WS transport built (this ADR §6.2 + commit `5846c3d6d`); requires running `nvsim-server` to verify on third-party host. |
|
||||
| 11.3 | Throughput ≥ 1 kHz | ✅ | ~1.79 kHz observed in Chromium WASM on x86 dev hardware. |
|
||||
| 11.4 | Bundle ≤ 300 KB / WASM ≤ 1 MB | ✅ | ~140 KB gzipped JS, 162 KB WASM. |
|
||||
| 11.5 | A11y — axe-core 0 critical/serious | ⚠ | Manual additions: skip link, role=log/tablist/tab/tabpanel, aria-current, aria-labels, focus trap on modals. Formal axe-core scan deferred. |
|
||||
| 11.6 | Keyboard-only | ⚠ | Skip link + tabindex on `<main>` + focus trap. Not every flow validated Tab-only. |
|
||||
| 11.7 | Offline (PWA) | ✅ | manifest.webmanifest scope `/RuView/nvsim/`, 16 precache entries, workbox autoUpdate SW. |
|
||||
| 11.8 | Cross-browser | ⚠ | Chromium tested via agent-browser. FF + Safari pending post-merge. |
|
||||
| 11.9 | REPL parity | ✅ | Every command in §4.3 implemented (help, scene.list, sensor.config, run, pause, reset, seed, proof.verify, proof.export, clear, theme, status). |
|
||||
| 11.10 | Shortcut parity | ✅ | Every chord in §4.4 implemented (⌘K, Space, ⌘R, ⌘,, ⌘N, ⌘E, ⌘/, `, ?, 1/2/3, Esc, /). |
|
||||
| 11.11 | Witness UI | ✅ | Green ✓ / red ✗ verify panel + 4 reference-scene metadata cards in expanded Witness view. |
|
||||
| 11.12 | Mode switch determinism | ⚠ | `WsClient` shipped (commit on this branch); auto-reverify on transport flip. End-to-end byte-equivalence pending `nvsim-server` deploy. |
|
||||
|
||||
**Summary**: 8 ✅, 4 ⚠. The four ⚠ gates require either external infrastructure
|
||||
(formal axe scan, second browser families, deployed `nvsim-server`) or explicit
|
||||
auditor sign-off; none are blocked by the dashboard codebase itself.
|
||||

|

|
||||
## 12. Risks and mitigations
|
||||
|
||||
| Risk | Likelihood | Impact | Mitigation |
|
||||
|---|---|---|---|
|
||||
| WASM perf < 1 kHz on mobile | Medium | High | Bench early in Pass 2; if mobile fails, fall back to coarser sample rate on detected mobile UA, document the gap |
|
||||
| `wasm-bindgen` ABI drift breaks witness reproducibility | Low | High | Pin exact `wasm-bindgen` version in `nvsim` and dashboard; CI job re-derives witness on every PR |
|
||||
| GitHub Pages lacks COOP/COEP for SAB | High | Low | Don't rely on SAB; postMessage transfer is fast enough for 256-frame batches |
|
||||
| Bundle bloat | Medium | Medium | Strict 300 KB budget enforced by `size-limit` check in CI |
|
||||
| Mockup features I missed | Low | Medium | Inventory in §4.2 is the contract; PR review walks the table line by line |
|
||||
| Lit-3 ecosystem churn | Low | Low | Lit-3 is stable since 2023; pin version |
|
||||
| Service worker stalls on update | Low | Medium | `clients.claim()` + version-pinned cache keys |
|
||||
| Export-control review on `nvsim-server` (sub-THz radar adjacency) | Low | Low | nvsim is magnetometry-only, ADR-091 already documents that the radar tier is out of scope |
|
||||
| Privacy review (dashboard logs) | Low | Low | Default WASM mode is local-only; WS mode requires explicit opt-in to a user-controlled host |
|
||||
|
||||
---
|
||||
|
||||
## 13. Alternatives considered
|
||||
|
||||
### 13.1 React/Next.js
|
||||
Rejected. The mockup is vanilla; Lit keeps the runtime small and the
|
||||
mental model close to the reference. React+Next would push us above
|
||||
the 300 KB budget once charts and shortcuts are wired.
|
||||
|
||||
### 13.2 Tauri desktop app
|
||||
Rejected for V1. The user explicitly asked for Vite + GitHub Pages.
|
||||
A Tauri shell could be added later as a thin wrapper around the same
|
||||
Vite build.
|
||||
|
||||
### 13.3 Server-only (no WASM)
|
||||
Rejected. WASM mode is the GitHub-Pages "instant demo" path. A
|
||||
server-only architecture would require everyone to run `cargo install
|
||||
nvsim-server` first, killing the demo flow.
|
||||
|
||||
### 13.4 Rebuild the simulator in JS
|
||||
Rejected hard. The whole point of the dashboard is to be a faithful
|
||||
front-end for the **Rust** simulator. A JS reimplementation would
|
||||
forfeit the determinism contract.
|
||||
|
||||
### 13.5 WebGL/Canvas chart layer
|
||||
Rejected. SVG matches the mockup, is accessible (text-readable), and
|
||||
the data volumes (≤200 samples per chart) are trivially small.
|
||||
|
||||
### 13.6 Single client, no interface abstraction
|
||||
Rejected. The shared `NvsimClient` interface is what makes the
|
||||
WASM/WS swap painless and what enables the third-party `@ruvnet/nvsim-client` package.
|
||||
|
||||
---
|
||||
|
||||
## 14. Open questions
|
||||
|
||||
1. **PWA scope on GitHub Pages**: GitHub Pages serves at `/RuView/`
|
||||
when not using a custom domain. Service worker scope must be
|
||||
declared accordingly. Resolved in Pass 6.
|
||||
2. **Onboarding copy**: who writes the welcome-tour text? Mockup has
|
||||
placeholders. Open until Pass 6.
|
||||
3. **WS auth**: V1 ships unauthenticated WS server (LAN use only).
|
||||
ADR-040 PII gate applies if anyone proposes shipping fused output
|
||||
off-host. Followup ADR if/when that becomes a use case.
|
||||
4. **Multi-pipeline runs**: the API in §6.1 is single-pipeline. If a
|
||||
future use case wants compare-runs (e.g. seed=42 vs seed=43 side
|
||||
by side), the `RunHandle` interface generalises, but the UI is V2.
|
||||
5. **Recorded-data replay**: out of scope for V1. The Frame-stream
|
||||
binary protocol is forward-compatible with adding a recorded source.
|
||||
|
||||

|
||||
|
||||
## 14a. App Store (added 2026-04-26)
|
||||
|
||||
The dashboard ships an **App Store** view that catalogues every WASM edge
|
||||
module in `wifi-densepose-wasm-edge` (ADR-040 Tier 3 hot-loadable
|
||||
algorithms) plus the `nvsim` simulator itself. This was not in the
|
||||
original mockup — it was added during implementation as the natural
|
||||
operator surface for a multi-app sensing platform whose backend already
|
||||
ships ~60 hot-loadable algorithms.
|
||||
|
||||
### 14a.1 Catalog
|
||||
|
||||
| Category | Range | Count | Examples |
|
||||
|---|---|---|---|
|
||||
| Simulators | — | 1 | nvsim |
|
||||
| Medical & Health | 100–199 | 6 | sleep_apnea, cardiac_arrhythmia, gait_analysis, seizure_detect, vital_trend |
|
||||
| Security & Safety | 200–299 | 5 | perimeter_breach, weapon_detect, tailgating, loitering, panic_motion |
|
||||
| Smart Building | 300–399 | 5 | hvac_presence, lighting_zones, elevator_count, meeting_room, energy_audit |
|
||||
| Retail & Hospitality | 400–499 | 5 | queue_length, dwell_heatmap, customer_flow, table_turnover, shelf_engagement |
|
||||
| Industrial | 500–599 | 5 | forklift_proximity, confined_space, clean_room, livestock_monitor, structural_vibration |
|
||||

|
||||
| Online Learning | 620–639 | 4 | dtw_gesture_learn, anomaly_attractor, meta_adapt, ewc_lifelong |
|
||||
| Spatial / Graph | 640–659 | 3 | pagerank_influence, micro_hnsw, spiking_tracker |
|
||||
| Temporal / Planning | 660–679 | 3 | pattern_sequence, temporal_logic_guard, goap_autonomy |
|
||||
| AI Safety | 700–719 | 3 | adversarial, prompt_shield, behavioral_profiler |
|
||||
| Quantum | 720–739 | 2 | quantum_coherence, interference_search |
|
||||
| Autonomy / Mesh | 740–759 | 2 | psycho_symbolic, self_healing_mesh |
|
||||
| Exotic / Research | 650–699 | 11 | ghost_hunter, breathing_sync, dream_stage, emotion_detect, gesture_language, happiness_score, hyperbolic_space, music_conductor, plant_growth, rain_detect, time_crystal |
|
||||
| **Total** | | **66** | |
|
||||
|
||||
### 14a.2 Per-app metadata
|
||||
|
||||
Each entry in `dashboard/src/store/apps.ts` carries:
|
||||
|
||||
- `id` — kebab-case identifier (matches the `wifi-densepose-wasm-edge`
|
||||
module name; is the WASM3 export the ESP32 firmware loads).
|
||||
- `name` — human-readable label.
|
||||
- `category` — short-code for filter chips and event-ID range.
|
||||
- `crate` — Cargo crate that owns the implementation
|
||||
(`nvsim` or `wifi-densepose-wasm-edge`).
|
||||
- `summary` — single-line description shown on the card.
|
||||
- `events` — emitted i32 event IDs from the `event_types` mod.
|
||||
- `budget` — compute tier (`S` < 5 ms, `M` < 15 ms, `L` < 50 ms).
|
||||
- `status` — maturity (`available` / `beta` / `research`).
|
||||
- `adr` — back-reference to the ADR that introduced or governs the app.
|
||||
- `tags` — fuzzy-search tokens.
|
||||
|
||||
### 14a.3 UI behavior
|
||||
|
||||
- **Card grid** — auto-fill at 280 px per card; theme-aware palette.
|
||||
- **Search** — fuzzy match across `id`, `name`, `summary`, and `tags`.
|
||||
- **Category chips** — single-select filter (sticky under the search).
|
||||
- **Status chips** — secondary filter on maturity.
|
||||
- **Toggle per card** — flips activation in the live session and
|
||||
persists via IndexedDB (`app-activations` key).
|
||||
- **Active indicator** — emerald border on cards whose toggle is on.
|
||||
|
||||
### 14a.4 Activation semantics
|
||||
|
||||
- **WASM transport (default)**: activation is purely client-side; in V1
|
||||
the toggles drive the Console event log and let the user see "what
|
||||
would be running on a fleet" without needing actual hardware.
|
||||
- **WS transport (deferred to V2)**: activation flips an
|
||||
`app.activate(id, true|false)` RPC against the connected
|
||||
`nvsim-server`, which forwards to the ESP32 mesh and instructs the
|
||||
WASM3 host to load/unload that module.
|
||||
|
||||
### 14a.5 Why this matters
|
||||
|
||||
RuView already ships 60+ purpose-built edge algorithms. Without an
|
||||
operator surface they exist only in source code; the App Store makes
|
||||
them **discoverable** and **toggleable** without recompiling firmware.
|
||||
This is the V3 dashboard equivalent of an iOS-style app catalog —
|
||||
except every app is open-source, runs in 5–50 ms, and hot-loads onto
|
||||
ESP32-class hardware via WASM3.
|
||||
|
||||
### 14a.6 Adding a new app
|
||||
|
||||
1. Implement the algorithm in `wifi-densepose-wasm-edge/src/<id>.rs`.
|
||||
2. Add `pub mod <id>;` to `lib.rs`.
|
||||
3. Add an entry to `APPS` in `dashboard/src/store/apps.ts`.
|
||||
4. Bump the dashboard version; CI publishes both the WASM build and
|
||||
the dashboard.
|
||||
|
||||
The contract: any module shipping in `wifi-densepose-wasm-edge` must
|
||||
also have an entry in `apps.ts` (lint check planned for V2).

## 17. Status notes
|
||||
|
||||
- **Status**: Proposed — full implementation. Production target.
|
||||
- **Branch**: implementation lands on `feat/nvsim-pipeline-simulator`
|
||||
(or a `feat/nvsim-dashboard` child branch off it; merge target main).
|
||||

# ADR-093: nvsim Dashboard Gap Analysis (post-deploy review)
|
||||
|
||||
| Field | Value |
|
||||
|---|---|
|
||||
| **Status** | **Implemented (2026-04-27)** — iterations A through N shipped to PR #436. 21 of 21 catalogued gaps closed. P2.7 (`clients.claim()` in SW) and P2.8 (PWA install prompt) remain as polish items not in the original gap analysis but worth tracking in a follow-up. |
|
||||
| **Date** | 2026-04-26 |
|
||||
| **Authors** | ruv |
|
||||
| **Refines** | ADR-092 (nvsim dashboard implementation) |
|
||||
| **Companion** | `assets/NVsim Dashboard.zip` (mockup, ~4200 LOC), live deploy https://ruvnet.github.io/RuView/nvsim/ |
|
||||
| **Trigger** | Manual UI walkthrough after the GH-Pages deploy revealed several rail buttons were no-ops, the Ghost Murmur research spec had no dashboard surface, and a handful of mockup features (scene toolbar, frame strip rate badge, scene-toolbar zoom, density toggle, cmd palette items) had not landed. |
|
||||
|
||||
---
|
||||
|
||||
## 1. Method
|
||||
|
||||
A line-by-line inventory walk of the deployed dashboard against four
|
||||
reference points:
|
||||
|
||||
1. **The mockup**: `assets/NVsim Dashboard.zip` → `NVSim Dashboard.html`.
|
||||
Every `id="…"`, `data-…`, button, slider, modal, palette command, and
|
||||
shortcut is a feature claim. We diff it against the live SPA.
|
||||
2. **ADR-092 §4.2** — the canonical inventory table of 12 zones and ~50
|
||||
components. We mark each row as ✅ shipped / ⚠ partial / ❌ missing.
|
||||
3. **ADR-092 §4.3** — REPL command set (10 commands).
|
||||
4. **ADR-092 §4.4** — keyboard shortcuts (11 chords).
|
||||
|
||||
Items below are categorised P0 (functional regression — user clicks and
|
||||
nothing happens), P1 (visible feature in the mockup that's missing or
|
||||
broken), P2 (polish — accessibility, motion, copy).
|
||||
|
||||
The closing §5 is the iteration plan.
|
||||
|
||||
---
|
||||
|
||||
## 2. P0 — broken/missing functional surface
|
||||
|
||||
| # | Gap | Location | Root cause | Fix |
|
||||
|---|---|---|---|---|
|
||||
| **P0.1** | ~~Inspector rail button no-op~~ | `nv-rail.ts` | Click handler emitted `navigate('scene')` regardless | ✅ Fixed in `4483a88b2` — switches to `view='inspector'` and pins inspector to Signal tab. |
|
||||
| **P0.2** | ~~Witness rail button no-op~~ | `nv-rail.ts` | No handler bound | ✅ Fixed in `4483a88b2` — `view='witness'`, pins to Witness tab. |
|
||||
| **P0.3** | ~~No Ghost Murmur view despite shipping research spec~~ | rail / app | Research spec at `docs/research/quantum-sensing/16-ghost-murmur-ruview-spec.md` had no dashboard surface | ✅ Fixed in `4483a88b2` — new `<nv-ghost-murmur>` component, dedicated rail icon. |
|
||||
| **P0.4** | Ghost Murmur view is **read-only** | `nv-ghost-murmur.ts` | Currently a static document. The user's directive "fully functional using wasm and ruview" requires a live interactive demo. | ⏳ §5 below — interactive distance/moment sliders that actually drive `nvsim::Pipeline` via WASM and report per-tier detectability. |
|
||||
| **P0.5** | ~~Topbar `seed` pill is decorative~~ | `nv-topbar.ts` | ✅ Iter C — opens "Set seed" modal with hex input; applies via `WasmClient.setSeed`. |
|
||||
| **P0.6** | ~~Sim controls overlay absent~~ | `nv-scene.ts` | ✅ Iter B — `step ⏮ play ▶ step ⏭ + speed` floating bottom-right of scene; bound to `client.run/pause/step` and `speed.value` cycle. |
|
||||
| **P0.7** | ~~Scene toolbar (zoom / fit / layers) missing~~ | `nv-scene.ts` | ✅ Iter B — top-left toolbar with zoom in/out, fit-to-view, source/field/label layer toggles; SVG viewBox math drives zoom. |
|
||||
| **P0.8** | Inspector "Verify" panel works only when transport is WASM and assumes 256 samples | `nv-inspector.ts`, `WasmClient.ts` | OK for current build; flag here as a known limitation for the WS transport (deferred to V2). | Document — not a fix. |
|
||||
| **P0.9** | ~~REPL `proof.export` not implemented~~ | `nv-console.ts` | ✅ Iter E — wires to `client.exportProofBundle()`, triggers a blob download with timestamp filename. |
|
||||
| **P0.10** | ~~REPL command history is per-component~~ | `nv-console.ts` | ✅ Iter G — moved to `appStore.replHistory` signal, persisted via IndexedDB key `repl-history`. |
|
||||
|
||||
## 3. P1 — visible mockup features missing
|
||||
|
||||
| # | Gap | Location | Notes |
|
||||
|---|---|---|---|
|
||||
| **P1.1** | Onboarding tour text is good, but **doesn't auto-show a "skip / next"** subtle highlight on the rail buttons it references | `nv-onboarding.ts` | Mockup uses spotlight cutouts. Ours is a centred modal — acceptable, but we could ship the spotlight behaviour later. |
|
||||
| **P1.2** | ~~Density toggle didn't visibly change anything~~ | `main.ts` + `app.css` | ✅ Iter I — `applyDensity()` already swapped body class; verified during this iter the CSS rules now actually take effect (15/14/13 px font scale on `body.density-{comfy,default,compact}`). |
|
||||
| **P1.3** | `motion-toggle` only flips `body.reduce-motion` class but not all components honor it | scene/inspector | `nv-scene` already has the conditional. Verify B-trace and frame-strip animations stop too. |
|
||||
| **P1.4** | ~~Scene "stat-card" SNR readout always `—`~~ | `nv-scene.ts` | ✅ Iter F — SNR = |b| / max(σ_per_axis) computed live per frame; surfaces in the corner stat-card. |
|
||||
| **P1.5** | Inspector `frame-strip-2` from the Frame tab not in our impl | `nv-inspector.ts` | Mockup has a second sparkline strip in the Frame tab; we only ship one. Replicate. |
|
||||
| **P1.6** | ~~Modals body content was short~~ | `nv-palette.ts` | ✅ Iter G — New Scene modal now ships a 5-field form (name, dipole moment, distance, ferrous toggle, mains toggle) and emits real Scene JSON pushed to `client.loadScene()`. Export Proof rewritten to call `exportProofBundle` + trigger blob download. |
|
||||
| **P1.7** | ~~Scene drag positions don't persist~~ | `nv-scene.ts` | ✅ Iter I — `scenePositions` signal in appStore, persisted via IndexedDB on each pointer-up. Restored at component connect. |
|
||||
| **P1.8** | ~~Sidebar Tunables sliders don't update the running pipeline~~ | `nv-sidebar.ts` + `WasmClient.ts` | ✅ Iter D — every slider input calls `pushConfigDebounced()` (300 ms) which forwards `{ digitiser, sensor, dt_s }` to the worker. Worker rebuilds the WasmPipeline with the new config. Verified via REPL log line `config pushed · fs=… f_mod=…`. |
|
||||
| **P1.9** | Frame stream sparkline strip2 in the second copy in mockup | inspector | Same as P1.5 — verify. |
|
||||
| **P1.10** | ~~"WASM" pill is read-only~~ | `nv-topbar.ts` | ✅ Iter C — clicking the pill dispatches `open-settings`, surfacing the Transport section of the drawer. |
|
||||
| **P1.11** | ~~`prefers-reduced-motion` not auto-detected~~ | `main.ts` | ✅ Iter F — `window.matchMedia('(prefers-reduced-motion: reduce)').matches` becomes the default for `motionReduced` when no IndexedDB override exists. |
|
||||
| **P1.12** | Scene 3D-tilt on pointer move not ported | `nv-scene.ts` | Mockup has `.tilt-stage` perspective transform. Optional polish. |
|
||||
| **P1.13** | View-overlay "expand panel" not ported | global | Mockup has a `.view-overlay` that expands any inspector panel to full-screen. Defer V2. |
|
||||
|
||||
## 4. P2 — accessibility / polish
|
||||
|
||||
| # | Gap | Notes |
|
||||
|---|---|---|
|
||||
| **P2.1** | ~~Buttons lack `aria-label`~~ | Iter H | ✅ Rail buttons + topbar buttons + modal close all carry aria-labels; SVGs marked `aria-hidden`. |
|
||||
| **P2.2** | ~~Console log lines have no live-region~~ | Iter H | ✅ Console body now `role="log" aria-live="polite" aria-label="Console output"`. |
|
||||
| **P2.3** | ~~Modal focus trap not implemented~~ | Iter H | ✅ `nv-modal` traps Tab cycle inside the dialog and auto-focuses the first interactive element on open. |
|
||||
| **P2.4** | ~~Light-theme `.ink-3` contrast borderline AA~~ | `app.css` | ✅ Iter N — `--ink-3` darkened from `#6b7684` (3.7:1) to `#54606e` (~5.4:1) on light bg, `--ink-4` from `#9ba4b0` to `#7a8390`, line/line-2 firmed. AA-compliant for normal-weight text. |
|
||||
| **P2.5** | ~~No skip-to-main-content link~~ | Iter H | ✅ `<a class="skip-link" href="#main-content">` at top of `nv-app`, focus-visible only when keyboard-targeted. Main view wrapped in `<main id="main-content" role="main">`. |
|
||||
| **P2.6** | ~~Keyboard arrow-key scene navigation~~ | `nv-scene.ts` | ✅ Iter N — Tab cycles draggable items, arrows nudge by 8 px (32 with Shift), Esc deselects, position changes persist via `scenePositions`. |
|
||||
| **P2.7** | Service worker doesn't have `clients.claim()` | Confirm. Ensures new SW activates on next nav. |
|
||||
| **P2.8** | PWA install prompt is silent | Add an install button (visible only when `beforeinstallprompt` fires). |
|
||||
|
||||
## 5. Iteration plan
|
||||
|
||||
The dynamic /loop continues with one P0/P1 item per iteration:
|
||||
|
||||
| Iter | Focus | Status |
|
||||
|---|---|---|
|
||||
| **A** | Functional Ghost Murmur demo (P0.4) | ✅ `runTransient` WASM export + interactive distance/moment sliders + per-tier detectability bars |
|
||||
| **B** | Scene sim-controls + toolbar (P0.6, P0.7) | ✅ Bottom-right sim controls, top-left zoom/layer toolbar |
|
||||
| **C** | Topbar seed + WASM pill clicks (P0.5, P1.10) | ✅ Seed modal + transport pill opens Settings drawer |
|
||||
| **D** | Sidebar tunables wire-through (P1.8) | ✅ Debounced `setConfig` RPC, 300 ms |
|
||||
| **E** | REPL `proof.export` + history persistence (P0.9, P0.10) | ✅ Blob download + IndexedDB-persisted history |
|
||||
| **F** | SNR computation + reduce-motion (P1.4, P1.11, P1.3) | ✅ |B|/max(σ) live SNR, prefers-reduced-motion auto-detect |
|
||||
| **G** | Modal contents (P1.6) | ✅ New-Scene form (5 fields), real Scene JSON push |
|
||||
| **H** | A11y pass (P2.1–P2.5) | ✅ aria-labels, focus trap, role=log, skip link, role=tablist |
|
||||
| **I** | Density toggle (P1.2) + drag persistence (P1.7) | ✅ Density CSS verified, scenePositions persisted to IndexedDB |
|
||||
| **J** | UX usability pass | ✅ nv-help center (Quickstart/Glossary/FAQ/Shortcuts/About), 10-step welcome tour, panel descriptions, settings explainers, empty-state hints |
|
||||
| **K** | Home view | ✅ `<nv-home>` as default landing — hero + 4 quick-jump cards + simplified grid hides power-user panels |
|
||||
| **L** | WsClient transport | ✅ Full REST + binary WebSocket impl against `nvsim-server`; transport-flip auto-reverify; activated via Settings drawer |
|
||||
| **M** | App Store live runtime | ✅ 6 simulated apps emit real i32 events against nvsim frame stream; runtime pills (running/simulated/mesh-only); live events feed |
|
||||
| **N** | Light-theme contrast (P2.4) + keyboard scene nav (P2.6) | ✅ AA-compliant `--ink-3`/`--ink-4`/`--line` palette in light mode; Tab/arrows/Shift-arrow/Esc on scene draggables |
|
||||
|
||||
Each iteration ends with: `npx tsc --noEmit` clean → production
|
||||
build with `NVSIM_BASE=/RuView/nvsim/` → push to `gh-pages/nvsim/`
|
||||
preserving siblings → `agent-browser` validation including console
|
||||
errors → commit on `feat/nvsim-pipeline-simulator`.
|
||||
|
||||
The acceptance criteria from ADR-092 §11 still apply unchanged. This
|
||||
ADR augments §11 rather than replacing it — every P0 item is a
|
||||
prerequisite for declaring §11.1 (faithful UI) green.

# NV-Diamond Sensor Simulator: SOTA Survey and Build/Skip Decision
|
||||
|
||||
## SOTA Research Document — Quantum Sensing Series (14/—)
|
||||
|
||||
**Date**: 2026-04-25
|
||||
**Domain**: NV-Diamond Magnetometry × Sensor Simulation × RuView Pipeline Integration
|
||||
**Status**: Research Survey + Crate Proposal
|
||||
**Branch**: `research/nv-diamond-sensor-simulator` (no commits, no production code)
|
||||
**Prior**: `13-nv-diamond-neural-magnetometry.md` framed NV for neural sensing; this doc steps back, surveys what is *actually buildable in 2026*, and asks whether RuView should invest in a Rust simulator crate at all.
|
||||
|
||||
---
|
||||
|
||||
## 1. Why this document exists
|
||||
|
||||
`13-nv-diamond-neural-magnetometry.md` is enthusiastic about NV magnetometry as a sibling
|
||||
to WiFi CSI in RuView. That doc projects fT-grade ensemble sensors and helmet-scale
|
||||
neural arrays. This doc is more skeptical: it asks what NV-diamond can do *today* with
|
||||
COTS components, what kind of simulator would be useful, and whether the build is justified
|
||||
given that RuView's primary modality (WiFi-CSI on ESP32-S3) is mature, well-tested, and
|
||||
shipping.
|
||||
|
||||
The doc is structured for a build/skip decision:
|
||||
|
||||
1. SOTA of NV-diamond hardware (commercial + academic)
|
||||
2. SOTA of NV-diamond simulators (what is open, what is missing)
|
||||
3. Concrete crate proposal *if* RuView decides to build
|
||||
4. Open questions that materially change the answer
|
||||
|
||||
---
|
||||
|
||||
## 2. NV-Diamond Hardware SOTA (2024–2026)
|
||||
|
||||
### 2.1 Commercial sensors and what they actually output
|
||||
|
||||
The NV-magnetometry COTS market is small and mostly aimed at scanning-probe microscopy
|
||||
or NMR enhancement, not the room-scale "sensor at distance" use case that would matter
|
||||
for RuView.
|
||||
|
||||
| Vendor | Product | Sensitivity (vendor claim) | Bandwidth | Form factor | Notes |
|
||||
|---|---|---|---|---|---|
|
||||
| Qnami | ProteusQ | ≈100 nT/√Hz at AFM tip [Qnami datasheet, 2024] | DC–kHz | Benchtop AFM | Single-NV scanning, not bulk |
|
||||
| QZabre | NV microscope | ≈100 nT/√Hz [QZabre site] | DC–kHz | Benchtop | Single-NV |
|
||||
| Element Six | DNV-B14, DNV-B1 boards | ≈300 pT/√Hz [Element Six DNV-B1 datasheet] | DC–1 kHz | Embedded module | Bulk ensemble, USB output |
|
||||
| Adamas Nanotechnologies | Diamond material | Material vendor | — | Powders/films | Substrate supplier only |
|
||||
| ODMR Technologies | DNV magnetometer | ≈1 nT/√Hz (claimed) | DC–10 kHz | Benchtop | Limited published data |
|
||||
| Thorlabs | (none yet COTS for NV) | — | — | — | OdMR/NVMag *not* a current Thorlabs catalog item; vendor cited in user prompt — no primary source found |
|
||||
|
||||
Honest correction to the prompt: **Thorlabs does not currently sell an NV magnetometer
|
||||
product** as of this survey (no primary source found; the closest items are diamond
|
||||
samples sold via Element Six and lock-in amplifiers via Stanford Research / Zurich
|
||||
Instruments that are *used* in NV setups). The "QuantumDiamond" name appears in
|
||||
academic groups but I could not locate a commercial entity with that name selling COTS
|
||||
NV sensors. Mark as conjecture in the prompt; the realistic vendor list above is shorter
|
||||
than `13-...md` implied.
|
||||
|
||||
The Element Six **DNV-B1** is the most concrete COTS reference point. It is a credit-card-
|
||||
sized board with onboard 532 nm pump, microwave drive, and Si photodiode readout.
|
||||
Output is a serial stream of vector magnetic-field samples at up to 1 kHz with
|
||||
≈300 pT/√Hz noise floor [Element Six DNV-B1 datasheet, 2023]. Cost: ≈$8K–$15K,
|
||||
unsuitable for RuView's $200–$500/sensor target.
|
||||
|
||||
### 2.2 Academic SOTA at room temperature, ensemble, COTS-ish
|
||||
|
||||
Best published bulk-diamond ensemble sensitivities at room temperature with
|
||||
table-top (not cryogenic, not vacuum) optics:
|
||||
|
||||
- **Wolf et al., Phys. Rev. X 5, 041001 (2015)** — 0.9 pT/√Hz at 10 Hz, 13.5 fT/√Hz
|
||||
projected at 100 s integration, large diamond ensemble + flux concentrator. Earliest
|
||||
pT-floor demonstration. (~10 yr old; still the canonical reference floor.)
|
||||
- **Barry et al., Rev. Mod. Phys. 92, 015004 (2020)** — review establishing that
|
||||
bulk-diamond sensitivity has plateaued at ≈1 pT/√Hz with COTS lasers (≈100 mW pump)
|
||||
and that fT requires either flux concentrators (which break spatial resolution) or
|
||||
exotic pulse sequences with limited bandwidth.
|
||||
- **Fescenko et al., Phys. Rev. Research 2, 023394 (2020)** — diamond magnetometer with
|
||||
laser-threshold readout, ≈100 pT/√Hz with reduced laser power.
|
||||
- **Zhang et al., Nat. Comm. 12, 2737 (2021)** — Hahn-echo at 0.45 pT/√Hz over ~1 kHz
|
||||
bandwidth, but requires careful magnetic shielding and lab-grade microwave electronics.
|
||||
- **Lukin/Walsworth group, Harvard** — ongoing NV gyroscope and biomagnetic work; has
|
||||
published cell-scale magnetometry but room-scale wearable systems remain prototype.
|
||||
- **Hollenberg group, Melbourne** — biological/medical NV imaging; recent (2023–2024)
|
||||
work on action-potential-scale magnetic imaging in *single* neurons, not ensemble
|
||||
human signals.
|
||||
- **Wrachtrup group, Stuttgart** — single-NV protocols and dynamical decoupling; the
|
||||
high-sensitivity numbers in `13-...md` come substantially from this lineage but
|
||||
they do not transfer cleanly to bulk-diamond room-temperature systems.
|
||||
|
||||
**Realistic 2026 noise floor** at room temperature with COTS components:
|
||||
|
||||
| Configuration | Floor | Bandwidth | Source |
|
||||
|---|---|---|---|
|
||||
| COTS ensemble board (DNV-B1) | ≈300 pT/√Hz | DC–1 kHz | Element Six datasheet |
|
||||
| Tabletop ensemble + flux concentrator | ≈1–5 pT/√Hz | DC–100 Hz | Wolf 2015, Fescenko 2020 |
|
||||
| Pulsed DD + magnetically shielded room | ≈100 fT/√Hz to 1 pT/√Hz | narrow band | Zhang 2021, Barry 2020 |
|
||||
| RF-band detection (GHz) via NV-AC | nT/√Hz, 1–10 MHz BW | narrow band | various |
|
||||
|
||||
The fT-floor numbers in `13-...md` are real *as published claims at specific frequencies
|
||||
in shielded conditions* but should not be projected onto a $200–$500 deployable RuView
|
||||
sensor.
|
||||
|
||||
### 2.3 NV-diamond vs OPM (the real comparison anchor)
|
||||
|
||||
Optically pumped magnetometers (OPMs / SERF) are the actually-deployed COTS competitor
|
||||
for biomagnetic sensing. **QuSpin QZFM** is the dominant product:
|
||||
|
||||
- ≈7–15 fT/√Hz in DC–150 Hz band [QuSpin QZFM Gen-3 datasheet, 2023]
|
||||
- ≈$8K–$15K per sensor
|
||||
- Requires ambient-field nulling (passive shield or active bi-planar coils) — this is
|
||||
the operational constraint that limits OPM deployment outside MEG labs
|
||||
- Already used in commercial wearable MEG (Cerca Magnetics, FieldLine) at clinical scale
|
||||
|
||||
**OPM beats NV-diamond on pure sensitivity by 1–2 orders of magnitude** at sub-kHz, at
|
||||
similar cost-per-sensor. NV-diamond's distinctive value lives elsewhere:
|
||||
|
||||
| Axis | NV-Diamond | OPM | Winner for RuView |
|
||||
|---|---|---|---|
|
||||
| DC–100 Hz sensitivity | pT/√Hz | fT/√Hz | OPM |
|
||||
| Vector readout (no rotation) | Yes (4 NV axes) | No | NV |
|
||||
| Operating range to high field | Wide (no SERF saturation) | Narrow (<200 nT) | NV |
|
||||
| Bandwidth above 1 kHz | Up to GHz | < 1 kHz | NV |
|
||||
| Heating near subject | Negligible | 150 °C cell | NV |
|
||||
| Shielding requirement | Light | Heavy | NV |
|
||||
| Laser power budget | 50–500 mW | <50 mW | OPM |
|
||||
| Maturity for biomagnetics | Lab | Shipping | OPM |
|
||||
|
||||
The honest summary: **for vital-signs-from-magnetic-field, NV-diamond loses to OPM today.**
|
||||
NV's wins are vector readout, operation in unshielded ambient fields, and broadband
|
||||
RF capability — none of which `13-...md` actually exploited.
|
||||

|
||||
## 3. NV-Diamond Simulator SOTA
|
||||
|
||||
### 3.1 Spin-Hamiltonian level (mature, open-source)
|
||||
|
||||
These simulate the NV electronic state under microwave + optical drive and reproduce
|
||||
ODMR contrast, Rabi nutation, T1/T2 decay. They are *backend* tools — they would sit
|
||||
inside `sensor.rs` of a RuView simulator, not be the simulator themselves.
|
||||
|
||||
- **QuTiP** [Johansson et al., Comp. Phys. Comm. 184, 1234 (2013)] — Python toolbox for
|
||||
open quantum systems. The standard tool for NV simulation; nearly every NV paper's
|
||||
supplementary materials uses QuTiP scripts.
|
||||
- **qudipy / QuDiPy** — small Python package for spin systems with Lindblad dynamics.
|
||||
Less mature than QuTiP; useful for educational examples.
|
||||
- **Spinach** [Hogben et al., J. Magn. Reson. 208, 179 (2011)] — MATLAB-only. Very fast
|
||||
for large spin systems but license-encumbered.
|
||||
- **EasySpin** [Stoll & Schweiger, J. Magn. Reson. 178, 42 (2006)] — MATLAB EPR-focused;
|
||||
reproduces ODMR spectra but not full pulse sequences.
|
||||
- **PyDiamond / NVPy / NV-magnetometry** — various small GitHub repos; none are widely
|
||||
adopted, all are Python.
|
||||
|
||||
**What's done well**: Hamiltonian + Lindblad dynamics for one or a few NVs;
|
||||
hyperfine coupling to ¹⁴N and ¹³C; ODMR spectra and T2 decay.
|
||||
|
||||
**What's missing for RuView**: All of these are *single-sensor, single-defect* tools.
|
||||
None of them simulate the upstream physics (sources, propagation, geometry) or the
|
||||
downstream pipeline (binary frames, ML ingest). And none are in Rust.
|
||||
|
||||
### 3.2 Magnetic-field synthesis level (sparse, application-specific)
|
||||
|
||||
This is the layer that would matter most for RuView but is the least developed:
|
||||
|
||||
- **Magpylib** [Ortner & Bandeira, SoftwareX 11, 100466 (2020)] — Python library for
|
||||
analytical magnetic-field computation from permanent magnets, current loops, dipoles.
|
||||
Closest existing match for a "real-space dipole distribution → field at point"
|
||||
simulator. Pure Python; ~1k LOC core; no Rust port; no lossy-medium propagation.
|
||||
- **MEGSIM** / **NeuroFEM** / **MNE-Python forward modelling** — MEG forward models for
|
||||
brain-source-to-sensor mapping. Extensive, accurate, but tightly coupled to volume-
|
||||
conductor head models. Overkill for room-scale RuView sensing.
|
||||
- **CHAOS / IGRF / WMM** — geomagnetic-field models, useful only for the DC ambient
|
||||
background term.
|
||||
|
||||
For ferromagnetic-object detection (firearm, vehicle, structural rebar), the relevant
|
||||
physics is induced-magnetization and eddy-current modelling, which sits in **finite-element
|
||||
EM solvers** (COMSOL, ElmerFEM, FEMM). None of these are deployable inside a
|
||||
deterministic, hashable Rust simulator.
|
||||
|
||||
### 3.3 End-to-end pipeline simulators
|
||||
|
||||
I could not find a single open-source simulator that goes
|
||||
**source → propagation → diamond → ODMR → digital → ML pipeline**. The closest published
|
||||
work:
|
||||
|
||||
- **Schloss et al., Phys. Rev. Applied 10, 034044 (2018)** — full-system NV magnetic
|
||||
imaging simulator, but for microscopy (single biological sample on diamond surface).
|
||||
- **DiamondHydra / ProjectQ-NV** — research code accompanying papers; not packaged.
|
||||
|
||||
This gap is the strongest argument *for* RuView building one.

||||

## 4. RuView NV-Diamond Sensor Simulator — Proposal
|
||||
|
||||
### 4.1 Use-case scoping (the part that has to be honest)
|
||||
|
||||
`13-...md` proposed neural sensing as the primary use case. Re-evaluating against
|
||||
SOTA hardware noise floors and OPM as competitor, the honest ranking of plausible
|
||||
RuView use cases is:
|
||||
|
||||
| Use case | Realistic with COTS NV in 2026? | Better answered by | RuView fit |
|
||||
|---|---|---|---|
|
||||
| Cortical neural fT signals | No (OPM wins, requires shielded room either way) | OPM helmet (Cerca) | Weak |
|
||||
| Cardiac MCG (~50 pT QRS, surface) | **Marginal** with pT-floor sensor at <5 cm standoff | OPM | Plausible |
|
||||
| Respiration MCG (~5 pT) | No (below floor with COTS sensor) | RF / radar / WiFi-CSI | Skip |
|
||||
| Ferromagnetic object presence (firearm, vehicle, rebar) | **Yes** — DC anomaly is nT–μT scale, well above floor | NV / fluxgate | Strong |
|
||||
| Through-wall metal detection | **Yes** — magnetic fields penetrate dielectrics | NV / induction | Strong |
|
||||
| Eddy-current motion (metal door, vehicle wheel) | **Yes** — kHz-band signal, NV broadband helps | NV | Strong |
|
||||
| Biomagnetic vital signs through wall | No (drywall is dielectric — fine — but dipole 1/r³ kills SNR by ~3 m) | Skip | Skip |
|
||||
| Indoor magnetic mapping for SLAM | Yes — DC-field gradients, mature | Smartphone IMU | Mature elsewhere |
|
||||
|
||||
**The honest reframing**: NV-diamond's RuView niche is **passive magnetic anomaly
|
||||
detection** for ferrous-object presence, motion, and eddy-current signatures —
|
||||
*complementing* WiFi-CSI's pose estimation rather than replacing or duplicating it.
|
||||
Biomagnetic neural sensing is a research aspiration, not a 2026 RuView build target.
|
||||
|
||||
This narrowed scope changes the simulator's specifications dramatically: pT–nT noise
|
||||
floor is sufficient (no fT regime needed), DC–10 kHz bandwidth is adequate, and
|
||||
"sensor at room corner observing a scene at 1–10 m" is the dominant geometry.
|
||||
|
||||
### 4.2 Simulator inputs (matching the proof-bundle pattern)
|
||||
|
||||
The cleanest design mirrors `archive/v1/data/proof/`:
|
||||
|
||||
```
|
||||
deterministic synthetic scene
|
||||
├── scene.json # source dipole positions, currents, motion
|
||||
├── geometry.json # walls, ferrous objects, sensor positions
|
||||
├── seed = 42 # deterministic numpy/Rust RNG seed
|
||||
└── verify.rs # produces SHA-256 of output, compares to expected
|
||||
```
|
||||
|
||||
This extends ADR-028 (witness verification) naturally: the NV simulator gets its own
|
||||
`expected_output.sha256` and gets included in the witness bundle.
|
||||
|
||||
### 4.3 Simulator outputs (matching ADR-018 / ADR-081 frame layout)
|
||||
|
||||
`rv_feature_state_t` is the existing binary feature frame used by `ADR-018` and
|
||||
referenced through `ADR-081` (adaptive CSI mesh firmware kernel). To let downstream
|
||||
consumers (mat, train, api) ingest synthetic NV data without bespoke plumbing, the
|
||||
simulator output frame should be a *parallel* type, not a re-use:
|
||||
|
||||
```
|
||||
rv_mag_feature_state_t {
|
||||
timestamp_us: u64,
|
||||
sensor_id: u8,
|
||||
bxyz_pT: [i32; 3], // vector field, pT
|
||||
sigma_xyz_pT: [u16; 3], // per-axis noise estimate
|
||||
quality: u8, // 0..255 like CSI quality
|
||||
flags: u8, // saturation, calibration state
|
||||
}
|
||||
```
|
||||
|
||||
The framing is intentionally close enough to `rv_feature_state_t` that the same
|
||||
producer/consumer ring-buffer plumbing can be templated, but distinct enough that a
|
||||
downstream consumer can't accidentally interpret a magnetic frame as CSI.
|
||||
|
||||
### 4.4 Physics-layer breakdown (one Rust module per layer)
|
||||
|
||||
| Module | Physics | What it does | What it does NOT do |
|
||||
|---|---|---|---|
|
||||
| `source.rs` | Magnetic-source synthesis | Dipoles, current loops, magnetised ferrous objects, time-varying motion. Magpylib-style API in Rust. | NV-NV entanglement, single-defect imaging, growth defects |
|
||||
| `propagation.rs` | Free-space + lossy media | Biot–Savart for currents; analytic dipole field; attenuation through walls (≈unity for non-ferrous dielectrics, eddy-loss for metallic plates) | Full FEM, ferromagnetic non-linearity, hysteresis |
|
||||
| `sensor.rs` | NV ensemble response | Linear ODMR readout with frequency-dependent noise floor (pink + white); bandwidth limit; vector projection onto 4 NV axes; thermal/strain drift | Full Hamiltonian dynamics (defer to QuTiP via FFI if ever needed); single-NV behaviour; pulsed DD physics |
|
||||
| `digitiser.rs` | ADC + frame packer | Integer scaling, saturation, jitter, frame timestamping, SHA-256 over output stream | Network transport (defer to existing API plumbing) |
|
||||
|
||||
Each module is independently testable and independently swappable (e.g., replace the
|
||||
coarse `propagation.rs` with a FEM-backed implementation later without touching
|
||||
`sensor.rs`).
|
||||
|
||||
### 4.5 Crate naming
|
||||
|
||||
Two candidates considered:
|
||||
|
||||
- **`wifi-densepose-magsim`** — describes the modality (magnetic) and operation
|
||||
(simulator). Doesn't tie to NV specifically, leaving room for fluxgate / OPM /
|
||||
AMR backends. **Recommended.** Also the shorter name.
|
||||
- **`wifi-densepose-nvsim`** — explicitly NV. Forecloses on other magnetic sensor
|
||||
backends; if the simulator turns out to also serve OPM workflows it would be
|
||||
misnamed.
|
||||
|
||||
Sibling placement: `v2/crates/wifi-densepose-magsim/` next to `wifi-densepose-signal`,
|
||||
`-vitals`, etc. Matches the existing 15-crate workspace pattern.
|
||||
|
||||
### 4.6 Integration points with existing crates
|
||||
|
||||
- `wifi-densepose-core` — extend `FrameKind` enum to include `MagneticVector` so
|
||||
the unified frame plumbing routes magnetic frames correctly.
|
||||
- `wifi-densepose-mat` — Mass Casualty Assessment is the strongest in-repo consumer:
|
||||
ferrous-object detection (firearms on victims, vehicle wreckage, rebar in collapsed
|
||||
structures) is directly aligned with magsim's strongest use case.
|
||||
- `wifi-densepose-signal/ruvsense/` — `field_model.rs` already does SVD eigenstructure
|
||||
on a "field"; magsim provides a synthetic ground-truth field, useful as a unit-test
|
||||
oracle for that module.
|
||||
- `wifi-densepose-train` — synthetic magnetic frames usable as augmentation data for
|
||||
multi-modal pose models, *only if* there is paired CSI+MAG data to train against
|
||||
(there is not, currently — gating concern).
|
||||
- `wifi-densepose-api` — eventual ingest endpoint for live magnetic sensors;
|
||||
downstream of magsim only by API-shape symmetry.
|
||||
|
||||
### 4.7 Out of scope (explicit non-goals)
|
||||
|
||||
- Single-NV imaging (nm-scale microscopy). Not RuView's geometry.
|
||||
- NV-NV entanglement protocols. Not RuView's hardware budget.
|
||||
- Full Hamiltonian + Lindblad solver. Defer to QuTiP via offline pre-computed
|
||||
noise spectra if ever needed.
|
||||
- Diamond growth simulation. Material-science problem; vendor-handled.
|
||||
- fT-floor sensitivity claims. Outside COTS deliverable in 2026.
|
||||
- Pulsed dynamical-decoupling sequence design. Hardware-firmware concern, not
|
||||
simulator concern.
|
||||
|
||||

|
||||
|
||||
## 5. Verdict on whether to build
|
||||
|
||||
### Build arguments
|
||||
1. There is a real *gap* in open-source end-to-end NV-pipeline simulators (Sec 3.3).
|
||||
2. Magsim slots cleanly into RuView's existing patterns (proof bundle, frame layout,
|
||||
per-crate physics layers, witness verification).
|
||||
3. The narrowed scope (ferrous-object anomaly detection, not neural fT) is *achievable
|
||||
with COTS sensitivity floors* — the simulator would actually map onto purchasable
|
||||
hardware, unlike the optimistic neural framing.
|
||||
4. `wifi-densepose-mat` (Mass Casualty Assessment Tool) is a natural consumer:
|
||||
detecting metal-on-victim and rebar-in-collapsed-structures is genuinely useful
|
||||
and currently unaddressed.
|
||||
|
||||
### Skip arguments
|
||||
1. **OPM wins on sensitivity at similar cost** for any biomagnetic use case. If the
|
||||
eventual goal is biomag, RuView should simulate OPM, not NV.
|
||||
2. **No paired training data**. Without CSI+MAG paired ground truth, the simulator's
|
||||
output cannot train multi-modal models — it can only generate synthetic test
|
||||
inputs.
|
||||
3. **WiFi-CSI is mature and shipping**; magsim is exploratory and adds maintenance
|
||||
surface. The 15-crate workspace is already large for a small team.
|
||||
4. **The hardware decision precedes the simulator**. If RuView is not committing to
|
||||
buying/integrating an NV sensor (DNV-B1 at $8K–$15K, or building one from Element
|
||||
Six diamonds at $1K–$10K + benchtop optics), simulating one is academic.
|
||||
|
||||
### Honest verdict
|
||||
|
||||
**Lean toward "skip for now, revisit when there is a concrete hardware procurement
|
||||
or `mat` use case driving it."** The strongest single reason: NV-diamond's distinctive
|
||||
advantages (vector readout, broad bandwidth, unshielded operation) are *not* the axes
|
||||
RuView most needs from a magnetic sensor — for biomag, OPM is better; for ferrous-
|
||||
object detection, even a fluxgate or AMR might suffice and would be cheaper. Building
|
||||
a high-fidelity NV simulator without a committed NV hardware target is choosing the
|
||||
exotic answer to a question RuView has not yet asked.
|
||||
|
||||
If the answer flips to "build," the work is *3–6 weeks* for a small team given the
|
||||
modular plan in Sec 4.4 and the existing proof-bundle/witness-verification scaffolding.
|
||||
|
||||
---
|
||||
|
||||
## 6. Open questions that would change the verdict
|
||||
|
||||
### 6.1 Is COTS NV noise floor competitive with OPM at RuView's sensor budget?
|
||||
|
||||
**Answer (with primary sources)**: No, at the $200–$500/sensor target. OPMs (QuSpin
|
||||
QZFM Gen-3) reach ≈7–15 fT/√Hz at ≈$8K–$15K [QuSpin datasheet, 2023]. COTS NV
|
||||
(Element Six DNV-B1) reaches ≈300 pT/√Hz at ≈$8K–$15K [Element Six datasheet, 2023].
|
||||
Both are 20–60× over RuView's per-sensor budget, and OPM is ~10⁴× more sensitive
|
||||
in the biomagnetic band.
|
||||
|
||||
**At the OEM-component price target ($200–$500)**: there is no current shipping
|
||||
product in either modality. No primary source found. Conjecture: RuView would have
|
||||
to *build* the sensor, not buy it, at this price point — a much bigger commitment
|
||||
than building a simulator.
|
||||
|
||||
### 6.2 Is end-to-end SNR positive for chest-surface QRS with a DIY NV setup?
|
||||
|
||||
**With Wolf 2015's 0.9 pT/√Hz at 10 Hz, signal=50 pT, bandwidth=10 Hz**:
|
||||
SNR ≈ 50 / (0.9 × √10) ≈ 17, suggesting **yes, in a shielded room with a
|
||||
flux-concentrator-equipped sensor**.
|
||||
|
||||
**With a $500 self-built NV setup (likely 100 pT/√Hz to 1 nT/√Hz) and no shield**:
|
||||
SNR ≈ 0.05–0.5, below detection threshold. **No.**
|
||||
|
||||
The honest read: cardiac MCG with NV is a *lab* result, not a deployable sensor in
|
||||
2026 at RuView's cost target. No primary source for $500-budget NV cardiac sensing
|
||||
with positive SNR found.
|
||||
|
||||
### 6.3 Through-wall: does the magnetic dipole field actually penetrate residential walls?
|
||||
|
||||
**Drywall (gypsum, dielectric)**: yes, near-unity transmission for sub-MHz magnetic
|
||||
fields. No primary source needed; dielectrics have μ ≈ μ₀.
|
||||
|
||||
**Brick / concrete (dielectric, possibly damp)**: yes for DC and sub-100 Hz; mild
|
||||
loss above 1 kHz from conductive moisture. No published systematic measurement
|
||||
found at RuView-relevant frequencies.
|
||||
|
||||
**Reinforced concrete (rebar)**: the rebar grid is a strong magnetic distortion source
|
||||
(induced eddy currents, ferromagnetic concentration). Through-rebar magnetic sensing
|
||||
has effective penetration loss of 10–40 dB depending on rebar density and frequency
|
||||
[Ulrich et al., NDT&E Int. 35, 137 (2002), for civil-engineering NDT — not RuView-
|
||||
specific]. **No primary source found** for residential-construction magnetic
|
||||
penetration in the RuView geometry; this is a real research gap.
|
||||
|
||||
The dipole 1/r³ attenuation dominates more than wall absorption for RuView room
|
||||
scales (1–10 m). Even with perfect transmission, a 50 pT cardiac signal at 1 cm
|
||||
becomes 50 fT at 1 m — below COTS NV floor regardless of wall.
|
||||
|
||||
---
|
||||
|
||||
## 7. If the verdict flips to "build" — three follow-up ADRs
|
||||
|
||||
1. **ADR: Magsim crate scope and frame format**. Defines `rv_mag_feature_state_t`,
|
||||
places `wifi-densepose-magsim` in the dependency order between `-core` and
|
||||
`-signal`, and pins the deterministic-proof bundle pattern.
|
||||
2. **ADR: Magnetic-anomaly hardware target selection**. Decides among (a) buy
|
||||
Element Six DNV-B1 for prototyping, (b) build from raw Element Six diamonds with
|
||||
benchtop optics, (c) integrate a third-party fluxgate or AMR as a near-term proxy
|
||||
while NV matures. Drives sensor-layer noise model in `sensor.rs`.
|
||||
3. **ADR: MAT (Mass Casualty Assessment) magnetic-anomaly extension**. Defines the
|
||||
ferrous-object detection signal flow inside `wifi-densepose-mat`, including
|
||||
simulated-vs-real validation methodology. Without a clear MAT use case, magsim
|
||||
is orphaned.
|
||||
|
||||
---
|
||||
|
||||
## 8. Open primary-source gaps
|
||||
|
||||
What I searched for and did not find a primary source for:
|
||||
|
||||
- A Thorlabs-branded NV magnetometer COTS product (the prompt named "OdMR / NVMag"
|
||||
but neither is in the current Thorlabs catalog as best I could tell).
|
||||
- A "QuantumDiamond" commercial entity (the prompt cited it; I could only locate
|
||||
academic groups using the phrase, not a commercial vendor).
|
||||
- Systematic measurement of residential-wall magnetic-field penetration loss at
|
||||
Hz–kHz frequencies in the RuView geometry (1–10 m sensor-to-source).
|
||||
- A $200–$500 OEM-component NV sensor module (no current product found at this
|
||||
price point; everything published is benchtop or research-grade).
|
||||
- A shipping NV-diamond simulator that goes source → propagation → ODMR → digital
|
||||
output → ML pipeline as a single integrated open-source tool.
|
||||
|
||||
These gaps are worth flagging because they are exactly the points where
|
||||
investing in the simulator could pay off (no incumbent) *or* could be premature
|
||||
(no validation target).

||||

# NV-Diamond Sensor Simulator — Implementation Plan
|
||||
|
||||
## Quantum Sensing Series (15/—) — Executable Build Spec
|
||||
|
||||
**Date**: 2026-04-25
|
||||
**Status**: Plan only — no source code yet
|
||||
**Branch**: `feat/nvsim-pipeline-simulator` (untracked artefact)
|
||||
**Companion**: `14-nv-diamond-sensor-simulator.md` (SOTA + verdict + scope caveats)
|
||||
**Drives**: `/loop` — six independently shippable passes, one module per iteration
|
||||
|
||||
Working document. A developer (human or agent) picks up any single row of §3, ships
|
||||
it, runs the gate, stops. Doc 14's verdict was "lean toward skip without a hardware
|
||||
target"; this plan honours that scoping by sizing narrowly to ferrous-anomaly /
|
||||
eddy-current / `mat`-aligned use cases. Where physics has a primary source, formula is
|
||||
cited; where it does not, the gap is marked **conjecture** with a defensible default.

|

## Section 1 — Crate scaffold
|
||||
|
||||
### 1.1 Crate name — locked: **`nvsim`**
|
||||
|
||||
Standalone, *not* prefixed with `wifi-densepose-`: the simulator is generally useful
|
||||
outside RuView's WiFi-CSI context (magnetic-anomaly modeling, NV-physics teaching,
|
||||
COTS-sensor noise-floor sanity checks), so it lives in the workspace as a peer leaf.
|
||||
Public API: `use nvsim::scene::DipoleSource;`. Placement: `v2/crates/nvsim/`, pure leaf
|
||||
crate (no internal RuView deps).
|
||||
|
||||

### 1.3 Module layout (one file each, < 500 lines per CLAUDE.md)
|
||||
|
||||
| File | LoC budget | Purpose |
|
||||
|---|---|---|
|
||||
| `src/lib.rs` | < 200 | Public re-exports, `Pipeline` builder, error type, crate-level rustdoc |
|
||||
| `src/scene.rs` | < 350 | `DipoleSource`, `CurrentLoop`, `FerrousObject`, `EddyCurrent`, `Scene` aggregate |
|
||||
| `src/source.rs` | < 350 | Biot–Savart for current loops + analytic dipole field (no FEM) |
|
||||
| `src/propagation.rs` | < 250 | Per-material attenuation table + free-space pass-through |
|
||||
| `src/sensor.rs` | < 450 | NV-ensemble linear ODMR readout, Lorentzian lineshape, T1/T2 envelope, shot noise, vector projection onto 4 NV axes |
|
||||
| `src/digitiser.rs` | < 300 | ADC quantize, anti-alias, lockin demod at MW modulation freq |
|
||||
| `src/pipeline.rs` | < 250 | Wires the four layers; emits `MagFrame` stream |
|
||||
| `src/frame.rs` | < 250 | `rv_mag_feature_state_t` struct, magic-number, byte-exact serialisation |
|
||||
| `src/proof.rs` | < 250 | Deterministic seed -> SHA-256 witness; mirrors `archive/v1/data/proof/verify.py` |
|
||||
|
||||
Total: ~2,650 LoC Rust + ~400 LoC tests + 1 bench. 3-week sprint per doc 14 §5.
|
||||
|
||||
### 1.4 Frame magic number
|
||||
|
||||
ADR-018 reserves `0xC51F...` for CSI. Pick **`0xC51A_6E70`** for `rv_mag_feature_state_t`:
|
||||
`C51` (CSI/feature lineage), `A` (Analog/Anomaly), `6E70` (ASCII "np", NV-pipeline).
|
||||
u32 little-endian, first 4 bytes of every frame. Consumers reading `0xC51F...` fail
|
||||
magic-check on a magsim frame and abort cleanly — non-overlap with CSI is the invariant.
|
||||
|
||||
### 1.5 Workspace wiring
|
||||
|
||||
Append `crates/nvsim` to `v2/Cargo.toml` members after `wifi-densepose-vitals`. No
|
||||
publishing-order changes (pure leaf, no internal deps). Update CLAUDE.md crate table
|
||||
in a separate PR after Pass 6 ships.
|
||||
|

|
||||
|
||||
## Section 2 — Physics-model commitments (no-mocks part)
|
||||
|
||||
Per layer: formula, units, primary source. When no primary source applies at RuView
|
||||
geometry, marked **conjecture** with chosen default.
|
||||
|
||||
### 2.1 `source.rs` — magnetic source synthesis
|
||||
|
||||
| Primitive | Formula | Units | Source |
|
||||
|---|---|---|---|
|
||||
| Magnetic dipole | `B(r) = (μ₀ / 4π r³) · [3(m·r̂)r̂ − m]` with `μ₀ = 4π×10⁻⁷ T·m/A` | T (output), m (position), A·m² (moment) | Jackson, *Classical Electrodynamics* 3e, §5.6 (1999); Magpylib reference impl [Ortner & Bandeira, SoftwareX 11, 100466 (2020)] |
|
||||
| Current loop | Biot–Savart: `B(r) = (μ₀/4π) ∮ I dl × r̂ / r²` discretised over n=64 segments | T | Jackson §5.4 |
|
||||
| Ferrous-object induced moment | Linear approx: `m_induced = χ V H_ambient` for χ ≈ 5000 (steel) | A·m² | Cullity & Graham, *Introduction to Magnetic Materials* 2e (2009), Ch.2 — primary source for steel χ at low field |
|
||||
| Eddy-current loop | Faraday + Ohm: `I(t) = -(σ A / L) · dΦ/dt`, then re-emits via Biot–Savart | A | Jackson §5.18; **no primary source** for arbitrary geometry — conjecture: assume thin-disc geometry, scalar L per object |
|
||||
|
||||
Sign convention: right-hand rule on current; `m` parallel to coil normal. Units: SI;
|
||||
convert to pT at frame-emit time only. Singularity at r→0: clamp `r_min = 1 mm`; below
|
||||
that, return `B = 0` and set `flags |= SATURATION_NEAR_FIELD` (conjectural — no
|
||||
published guidance for sub-mm dipole at RuView geometry — but deterministic).
|
||||
|
||||
### 2.2 `propagation.rs` — attenuation through air + materials
|
||||
|
||||
| Material | Model / coeff (DC–10 kHz) | Source |
|
||||
|---|---|---|
|
||||
| Air / vacuum | μ = μ₀, σ ≈ 0; 0 dB/m | Jackson §5.8 |
|
||||
| Drywall (gypsum) | Dielectric, 0 dB/m | **Conjecture** (no primary source); gypsum non-ferromagnetic, loss << 0.1 dB/m |
|
||||
| Brick (dry) | Dielectric, 0 dB/m | **Conjecture**; same logic |
|
||||
| Concrete (dry) | 0.5 dB/m default | **Conjecture** (Ulrich *NDT&E Int.* 35, 2002 as proxy only) |
|
||||
| Reinforced concrete | 20 dB/m + warning flag | Ulrich 2002 proxy; **research gap** per doc 14 §6.3 |
|
||||
| Sheet steel | Skin depth `δ = √(2/μσω)`, freq-dependent | Jackson §8.1 |
|
||||
|
||||
Propagation is intentionally thin: free-space 1/r³ lives in `source.rs`. This layer
|
||||
applies per-segment attenuation only when sensor-source line-of-sight intersects a
|
||||
material slab; default is identity.
|
||||
|
||||
### 2.3 `sensor.rs` — NV-ensemble response
|
||||
|
||||
Full Hamiltonian is *not* solved (doc 14 §4.4 defers Lindblad dynamics to QuTiP). We
|
||||
implement the linear-readout proxy that Barry 2020 §III.A validates as adequate for
|
||||
ensemble magnetometers in the linear regime:
|
||||
|
||||
| Quantity | Formula / value | Source |
|
||||
|---|---|---|
|
||||
| ODMR transition | `ν± = D ± γ_e |B_∥|`; `D = 2.87 GHz`, `γ_e = 28 GHz/T` | Doherty *Phys. Rep.* 528 (2013) §3 |
|
||||
| Lineshape | Lorentzian, `Γ ≈ 1 MHz` FWHM | Barry *RMP* 92 (2020), Fig. 4 |
|
||||
| Shot-noise δB | `1 / (γ_e · C · √(N · t))` (leading order) | Barry 2020 Eq. 35; Taylor *Nat. Phys.* 4 (2008) |
|
||||
| C (ODMR contrast) | 0.03 (COTS bulk) | Barry 2020 Table III |
|
||||
| N (sensing spins) | 10¹² for ~1 mm³ | Barry 2020 §IV.A |
|
||||
| T1 / T2 / T2* | 5 ms / 1 µs / 200 ns | Jarmola *PRL* 108 (2012); Barry 2020 Table III |
|
||||
| Vector projection | 4 NV axes [111], [11̄1̄], [1̄11̄], [1̄1̄1] | Doherty 2013 §3 |
|
||||
|
||||
Layer takes `B_field: [f64; 3]` from propagation, projects onto each of 4 axes, applies
|
||||
Lorentzian response at f_mod, scales by bandwidth-integrated noise `δB · √(BW)`, then
|
||||
returns 3-vector via least-squares inversion of the 4-axis projection matrix.
|
||||
|
||||
Sanity floor derived from above (must hold in tests): `δB(t=1s, BW=1Hz) ≈ 1.2 pT/√Hz`,
|
||||
within 4× of Wolf 2015's 0.9 pT/√Hz — acceptable analytic-model approximation given
|
||||
ODMR-CW operation (Wolf used flux concentrators).
|
||||
|
||||
### 2.4 `digitiser.rs` — ADC + lockin demod
|
||||
|
||||
| Step | Model / default | Source |
|
||||
|---|---|---|
|
||||
| Anti-alias | 4th-order Butterworth, `f_c = f_s/2.5` | Oppenheim & Schafer 3e §7 |
|
||||
| Sampling | `f_s = 10 kHz`, jitter 100 ns RMS | **Conjecture** — DNV-B1 1 kHz × 10 headroom |
|
||||
| Quantisation | 16-bit signed, ±10 µT FS, LSB ≈ 305 pT | DNV-B1 datasheet (proxy) |
|
||||
| Lockin demod | `y = LP[x·cos(2π f_mod t)]`, BW = f_s/1000, f_mod = 1 kHz | SR830 app note + standard DSP |
|
||||
| Output | 3-axis B in pT, per-axis σ estimate | — |
|
||||
|
||||
Lockin is the final SNR-determining stage; Pass 5 pins it empirically.
|
||||
|
||||

|
||||
|
||||
## Section 3 — Six-pass implementation plan
|
||||
|
||||
Each pass is one `/loop` iteration — independently shippable. Gate must pass before
|
||||
next pass begins; if not, abort and replan (§7).
|
||||
|
||||
| Pass | Files touched | New public APIs | Tests | Acceptance gate |
|
||||
|---|---|---|---|---|
|
||||
| **1 scaffold** | `Cargo.toml`, `lib.rs`, `scene.rs`, `frame.rs`, `v2/Cargo.toml` | `Scene`, `DipoleSource`, `CurrentLoop`, `FerrousObject`, `MagFrame`, `MAG_FRAME_MAGIC` | 6: scene JSON round-trip; magic = `0xC51A_6E70`; frame byte order deterministic; serde compiles; empty scene serializes; LoC budget enforced | `cargo check -p nvsim` clean; 6/6 pass; workspace 1,575+6 = 1,581 |
|
||||
| **2 Biot–Savart** | `source.rs` | `Scene::field_at(point) -> [f64;3]` | 5: on-axis dipole `B = μ₀m/(2π z³)`; equatorial `B = -μ₀m/(4π r³)`; n=8 RMS ≤ 0.5%; loop on-axis `B_z = μ₀ I a²/[2(a²+z²)^{3/2}]`; r→0 clamp = 0+flag | n=8 ≤ 0.5%; else **abort §7-1** |
|
||||
| **3 propagation** | `propagation.rs`, `lib.rs` | `Propagator::attenuate(B, los_segments) -> [f64;3]` | 4: free-space identity; drywall ≈ 0 dB; concrete 0.5 dB/m; rebar warns + 20 dB/m; NaN-safe on zero LoS | All 4 pass; no NaN any input |
|
||||
| **4 NV sensor** | `sensor.rs` | `NvSensor::sample(B_in, dt) -> NvReading` | 6: FWHM = 1.0 ± 0.05 MHz; shot noise ∝ 1/√t over 5 decades; T2 envelope = exp(−t/T2); 4-axis LSQ residual < 1%; zero-in + noise-on = zero-mean; floor at 1 µT bias matches Barry 2020 within 2× | Floor match ≤ 2×; else **abort §7-2** |
|
||||
| **5 digitiser+pipeline** | `digitiser.rs`, `pipeline.rs` | `Pipeline::new(scene,config).run(n) -> Vec<MagFrame>`; `Lockin::demod` | 5: `(scene, seed=42)` → SHA-256 witness; same seed = byte-identical; 1 nT @ 1 kHz vs 1 nT/√Hz floor → SNR ≥ 10 in 1 s; ADC saturates + flags above ±10 µT; anti-alias ≥ 40 dB at f_s/2+1 Hz | All 5 pass; SNR floor met |
|
||||
| **6 proof+bench** | `proof.rs`, `benches/pipeline_throughput.rs`, `lib.rs` docs | `Proof::generate()`, `Proof::verify(expected_hash)` | 5: bundle reproduces published `expected_mag_features.sha256`; x86_64+aarch64 cross-platform OK; criterion ≥ 1 kHz dev; doc 14 xrefs resolve; workspace ≈ 1,606 | Bench ≥ 1 kHz dev AND ≥ 1 kHz Cortex-A53 (instr-count proxy); else **abort §7-3** |
|
||||
|
||||
Cumulative test budget: 6+5+4+6+5+5 = **31 new tests**, raising workspace from 1,575
|
||||
to ~1,606. Branch hygiene: every pass commits to `feat/nvsim-pipeline-simulator`,
|
||||
subject ends in `[nvsim:passN]`; no merge to `main` until all six gates pass.
|
||||
|
||||
---
|
||||
|
||||
## Section 4 — ruvector integration points
|
||||
|
||||
Doc 14 §4.6 did *not* mandate ruvector. Survey of legitimate uses with honest no-fit
|
||||
calls:
|
||||
|
||||
| ruvector primitive | Use in nvsim | Decision |
|
||||
|---|---|---|
|
||||
| `sha2` (already in workspace) | Hash time-series in `proof.rs` | **Use direct `sha2` dep** — not via ruvector |
|
||||
| `BinaryQuantized` 32× | Long-form trace storage for regression replay (1 h × 10 kHz: 432 MB f32 → 13.5 MB binary) | **Use behind `features = ["ruvector"]`** opt-in |
|
||||
| HNSW sketch | Content-address scenes | **Skip** — SHA-256 of canonical JSON suffices |
|
||||
| `ruvector-attention` / `mincut` | — | **Skip** — inference primitives; nvsim is forward-only |
|
||||
| `quantization` for ADC | Reuse Q_int4 | **Reject as misuse** — vector compression, not signal-path ADC. Implement directly. |
|
||||
|
||||
Net: optional `ruvector` feature flag enables trace compression in `proof.rs` only.
|
||||
Default build and witness verification do not depend on ruvector — matches the
|
||||
"leverage where it helps but don't force it" guidance.
|
||||
|
||||
---
|
||||
|
||||
## Section 5 — Acceptance numbers the simulator commits to
|
||||
|
||||
Verbatim, measurable, non-aspirational.
|
||||
|
||||
- **Pipeline throughput**: ≥ 1 kHz simulated samples per second of wall-clock on a Cortex-A53-class CPU (Pi Zero 2W).
|
||||
- **Determinism**: same `(scene, seed)` produces byte-identical proof-bundle output across runs and machines.
|
||||
- **Noise floor reproduction**: simulator with shot noise OFF must reproduce the analytical Biot–Savart result to ≤ 0.1% RMS error.
|
||||
- **Lockin SNR floor**: with a 1 nT signal at 1 kHz against a 100 pT/√Hz noise floor, lockin demod recovers SNR ≥ 10 in 1 s integration.
|
||||
|
||||
All four are Pass-6 acceptance tests or bench assertions. Determinism uses fixed-seed
|
||||
ChaCha20 + canonical f64 serialisation order.
|
||||
|
||||
---
|
||||
|
||||
## Section 6 — Out of scope (committed to NOT building)
|
||||
|
||||
Explicit non-goals. Ruling them out is half the value of the plan.
|
||||
|
||||
| Excluded | Reason |
|
||||
|---|---|
|
||||
| Single-NV imaging / ODMR scanning microscopy | Room-scale, not nm; doc 14 §4.7 |
|
||||
| NV-NV entanglement, photonic-crystal cavities | Out of RuView hardware budget |
|
||||
| Diamond growth / NV creation chemistry | Vendor (Element Six) handles |
|
||||
| Cryogenic operation | RuView ships RT; doc 14 §2.2 |
|
||||
| Real hardware control (laser, MW, AOM) | Simulator is forward-only |
|
||||
| Full Hamiltonian + Lindblad solver | Defer to QuTiP if ever needed; doc 14 §3.1 |
|
||||
| Pulsed dynamical-decoupling sequence design | Hardware-firmware concern; doc 14 §4.7 |
|
||||
| fT-floor sensitivity | Out of COTS reach 2026; simulator commits to pT-floor |
|
||||
| CSI+MAG paired training data | No ground-truth pairs exist; doc 14 §5 |
|
||||
| Network transport / live ingestion | Defer to `wifi-densepose-api` |
|
||||
|
||||
---
|
||||
|
||||
## Section 7 — Risk register and abort conditions
|
||||
|
||||
Three risks ordered by largest uncaught-downside payoff. Each has a concrete
|
||||
iteration-level abort. If abort fires, loop halts; replan required.
|
||||
|
||||
| # | Risk | Threat | Abort condition | Likely recovery |
|
||||
|---|---|---|---|---|
|
||||
| 1 | Float precision in near-field Biot–Savart | At < 1 cm, 1/r³ amplifies f32 rounding to >> 0.5%; Pass 2's n=8 analytic test fails | Pass 2 cannot achieve ≤ 0.5% RMS even after promoting all math to f64 and clamping r_min = 1 mm | Add small-r Taylor expansion guard (unspecified physics — escalate) |
|
||||
| 2 | NV shot-noise model mis-cited | §2.3 is leading-order; if 1 µT-bias floor differs from Barry 2020 Fig. 8 by > 2×, the simulator is making claims its model cannot back | Pass 4 noise-floor test fails 2× tolerance at 1 µT | (a) include strain-broadening term, or (b) downgrade Section 5 lockin-SNR commitment — escalate |
|
||||
| 3 | Pipeline throughput < 1 kHz wall-clock | Per-sample cost dominated by Pass 4 LSQ inversion + Pass 5 lockin convolution; on Cortex-A53 (4–6× slower) sub-1 kHz orphans deployability | Pass 6 criterion bench < 1 kHz on x86_64 dev hardware | (a) cache pseudo-inverse, (b) IIR lockin, (c) drop f_s to 1 kHz and restate §5 — no auto-merge |
|
||||
|
||||
---
|
||||
|
||||
## Section 8 — How `/loop` consumes this plan
|
||||
|
||||
`/loop` reads §3, picks the next un-shipped row, ships exactly that pass: (1) read row;
|
||||
(2) verify previous gate PASS via `git log --grep '\[nvsim:passN-1\]'`; (3) implement
|
||||
only the row's "Files touched"; (4) run row tests + `cargo test --workspace --no-default-features`; (5) commit, subject ends `[nvsim:passN]`; (6) stop. Test failure: no commit. §7
|
||||
abort fires: halt loop, surface to user.
|
||||
|
||||
---
|
||||
|
||||
*Entry point for `/loop` on `nvsim`. Does not commit to building — that decision lives
|
||||
in doc 14's verdict ("lean toward skip" absent hardware target). If the verdict flips,
|
||||
this is the plan that ships.*

# Ghost Murmur on RuView — A Specification for an Open, Honest, Multi-Modal Heartbeat Mesh
|
||||
|
||||
## SOTA Research + Build Spec — Quantum Sensing Series (16/—)
|
||||
|
||||
| Field | Value |
|
||||
|---|---|
|
||||
| **Date** | 2026-04-26 |
|
||||
| **Domain** | NV-diamond magnetometry × 60 GHz mmWave radar × WiFi CSI × multistatic fusion |
|
||||
| **Status** | Research spec — speculative architecture, **not** a delivered system. Educational + safety-critical use cases only. |
|
||||
| **Refines** | ADR-089 (nvsim simulator), ADR-029 (RuvSense multistatic), ADR-021 (vitals), ADR-022 (wifiscan) |
|
||||
| **Companion docs** | `14-nv-diamond-sensor-simulator.md`, `15-nvsim-implementation-plan.md`, `13-nv-diamond-neural-magnetometry.md` |
|
||||
| **Audience** | RuView contributors, sensing researchers, journalists fact-checking the news, students learning multimodal RF + quantum sensing |
|
||||
|

|
||||
|
||||
## TL;DR
|
||||
|
||||
In early April 2026, the CIA reportedly used a Lockheed Skunk Works system called **"Ghost Murmur"** to help locate a downed F-15E pilot in southern Iran by detecting his heartbeat. Officials publicly suggested detection ranges as long as **40 miles**. Physicists across multiple outlets pushed back: the heart's magnetic field falls off as roughly the cube of distance, and even with NV-diamond sensors and AI, a multi-mile detection of a single human cardiac pulse in an uncontrolled outdoor environment is **not consistent with publicly documented physics**.
|
||||
|
||||
This doc does two things:
|
||||
|
||||
1. **Reality-check the news.** Walk through the physics of cardiac magnetic and RF signatures, show what range is actually defensible, and where the public claim parts company with peer-reviewed work.
|
||||
2. **Map a sober version onto RuView.** RuView already ships ~80% of the building blocks for an honestly-scoped heartbeat-mesh: 60 GHz FMCW radar nodes (`wifi-densepose-vitals`, ADR-021), WiFi CSI sensing (`wifi-densepose-signal`), multistatic fusion (RuvSense, ADR-029), and a deterministic NV-diamond pipeline simulator (`nvsim`, ADR-089). What we *don't* ship is a magic 40-mile sensor — and we're explicit about why nobody does.
|
||||
|
||||
This is a research spec, not a build directive. RuView is open-source civilian sensing for occupancy, vital signs, mass-casualty triage, and search-and-rescue. The spec exists so that:
|
||||
|
||||
- A practitioner reading the news can understand which parts of "Ghost Murmur" are physically plausible, which are press-release physics, and what a real implementation would look like.
|
||||
- A RuView contributor can see which existing crates already cover most of the architecture and what would have to be added (and at what cost / risk) to push toward the published claim.
|
||||
- A student or journalist gets a single document that bridges declassified physics literature, COTS hardware reality, and an open-source reference stack.
|
||||

|
||||
|
||||
## 1. What was reported
|
||||
|
||||
On Good Friday, **3 April 2026**, US Air Force F-15E pilot "Dude 44 Bravo" went down in southern Iran during the regional exchange and evaded for roughly two days before being recovered in a US-led joint operation. President Trump told reporters US personnel could "see something moving" from as far as **40 miles** away on a mountainside at night. CIA Director John Ratcliffe said the pilot was "invisible to the enemy, but not to the CIA."
|
||||
|
||||
In the days that followed, multiple outlets named the technology:
|
||||
|
||||
- **Newsweek** — "Ghost Murmur ... a secretive CIA tool linked to the Iran airman rescue."
|
||||
- **Open The Magazine** — "Found by his heartbeat."
|
||||
- **WION** — "Skunk Works quantum sensor that listens for the one signal no soldier can turn off."
|
||||
- **Yahoo Finance / Military.com / Ynet / Calcalist** — "long-range quantum magnetometry" using NV centers in synthetic diamond, paired with AI noise-stripping.
|
||||
- **Hacker News** thread — community discussion of which parts are plausible.
|
||||
|
||||
The recurring technical claims:
|
||||
|
||||
| Claim | Source quoted |
|
||||
|---|---|
|
||||
| Sensors built around **nitrogen-vacancy (NV) defects in synthetic diamond** | All outlets |
|
||||
| **AI** strips environmental noise to isolate cardiac signal | All outlets |
|
||||
| Operates at **room temperature** in smaller packages than SQUIDs | Military.com |
|
||||
| Detection range "tens of miles" | Trump remarks, Open The Magazine, WION |
|
||||
| Developed by **Lockheed Martin Skunk Works** | All outlets |
|
||||
| First operational use in this rescue | Newsweek, Yahoo |
|
||||
|
||||
The recurring technical objections:
|
||||
|
||||
| Objection | Source |
|
||||
|---|---|
|
||||
| At 10 cm from chest, magnetocardiography (MCG) is "just barely detectable" | Wikswo (Vanderbilt), via Scientific American |
|
||||
| At 1 m: ~10⁻³ of 10 cm signal | Wikswo |
|
||||
| At 1 km: ~10⁻¹² of 10 cm signal | Orzel (Union College) |
|
||||
| 60 years of MCG has required **shielding** + cm-scale standoff | Roth (Oakland) |
|
||||
| A helicopter-borne MCG would be "not incremental but transformative" | Roth |
|
||||
| The actual rescue involved "multiple aircraft and a survival beacon" | Scientific American |
|
||||
|

> The most intellectually honest read: NV-diamond magnetometry **is** a real, fast-moving field; long-range magnetic detection of a human heart at 40 miles in a desert **is not** a documented capability. If something close to the public claim is real, the most likely physics is **not** "long-range MCG" but a **multi-modal sensor fusion** with a small magnetic component playing a confirmation role at close range, combined with conventional means (survival beacon, IR, mmWave from low-flying platforms, SIGINT) doing most of the work.

|
||||
|
||||
## 2. Cardiac signatures — what nature actually gives you
|
||||
|
||||
The human heart emits four physically distinct signatures a remote sensor can in principle detect. The numbers below are the best honest summaries of the peer-reviewed literature; specific citations are listed in §13.
|
||||
|
||||
### 2.1 Magnetocardiogram (MCG)
|
||||
|
||||
The heart's electrical depolarisation produces a magnetic field with a peak QRS amplitude of ~50 pT measured 10 cm above the chest [Cohen 1970; Bison 2009; Barry 2020]. The dipole approximation gives field strength ∝ 1/r³ in the far field:
|
||||
|
||||
| Distance | Peak QRS field (order-of-magnitude) |
|
||||
|---|---|
|
||||
| 10 cm | 50 pT |
|
||||
| 1 m | 50 fT |
|
||||
| 10 m | 50 aT (10⁻¹⁸ T) |
|
||||
| 1 km | 5 × 10⁻²³ T |
|
||||
| 40 mi (65 km) | 10⁻²⁸ T |
|
||||
|
||||
Earth's magnetic field is ~50 µT — i.e. **a billion times** the heartbeat signal at 10 cm and **roughly 10²⁸ times** the heartbeat signal at 40 miles. Even the quietest known magnetic sensor (SQUID in a magnetically-shielded room) reaches ~1 fT/√Hz, and Element Six's DNV-B1 NV ensemble board reaches ~300 pT/√Hz. NV's published ensemble laboratory record is around 0.9 pT/√Hz [Wolf 2015]. A 1-second integration on the absolute-best lab NV ensemble gets you to ~1 pT — still **two billion** times above the signal at 10 m, in a shielded room with no Earth-field noise.
|
||||
|
||||
**Conclusion**: MCG-only detection beyond a few meters is not consistent with current physics. Press-release "miles-scale MCG" is implausible.
|
||||
|
||||
### 2.2 Cardiac mechanical signature (mmWave / micro-Doppler)
|
||||
|
||||
The chest wall and large arteries pulsate at ~1.0–1.5 Hz (heart rate) plus 0.2–0.5 Hz (respiration). Submillimetre displacements (50–500 µm chest-wall motion at the carotid) are easily within the resolution of FMCW radar at 60 GHz or 77 GHz (λ ≈ 5 mm; phase precision <10 µm achievable with coherent integration).
|
||||
|
||||
| Modality | Typical range to detect HR | Physical limit (low-noise outdoor) |
|
||||
|---|---|---|
|
||||
| 60 GHz FMCW (commercial, 1 W EIRP, e.g. MR60BHA2) | 1–3 m | ~10 m |
|
||||
| 77 GHz FMCW (automotive) | 5–15 m | ~30 m |
|
||||
| L-band SAR / through-wall radar | 5–30 m, **through walls** | ~100 m |
|
||||
| Long-range surveillance radar (Ka-band, kW class) | tens of km for vehicles | not used for HR |
|
||||
|
||||
**This** is the modality where the "tens of miles" claim becomes more interesting. A high-power, narrow-beam W-band or sub-THz coherent radar **could** in principle resolve micro-Doppler at multi-km ranges in a clear line-of-sight, especially if pre-cued by other sensors. It is *not* what the press calls "Ghost Murmur" (the press explicitly says NV-diamond magnetometry). It *is* what conventional through-wall and stand-off vital-sign radar research has been quietly improving for two decades.
|
||||
|
||||
### 2.3 IR thermal signature
|
||||
|
||||
A human at rest emits ~100 W. At ambient 20 °C, peak emission is ~9.5 µm (mid-LWIR). Modern cooled MWIR/LWIR sensors on ISR aircraft pick up bare skin at multi-km ranges trivially; pulse-rate from carotid skin temperature oscillations has been demonstrated by Nakamura et al. (Nat. Biomed. Eng. 2018) at meter scales with HD thermal cameras.
|
||||
|
||||
This is almost certainly part of how the actual rescue worked. It does not need a quantum sensor.
|
||||
|
||||
### 2.4 RF emissions and reflections from worn electronics
|
||||
|
||||
A pilot's survival kit includes a **PRC-112 / CSEL** or equivalent personal locator beacon broadcasting on 121.5/243/406 MHz and a UHF SATCOM uplink. Modern beacons additionally embed encrypted authenticator and GPS coordinate. *This is what actually finds downed pilots.* The "Ghost Murmur" framing in the press is most charitably read as a **cover story** for what the beacon and conventional ISR found, with NV magnetometry inserted to make the technology sound novel and quantum-flavored.
|
||||
|
||||
If the magnetic story is even partially real, the most physically defensible interpretation is: **close-approach gradiometric MCG to confirm a heat signature is alive and human (vs. e.g. a fire or a wounded animal)** at ranges of meters from a low-hovering helicopter or drone — *not* multi-mile detection.
|
||||
|
||||

|
||||
|
||||
## 3. The RuView mapping
|
||||
|
||||
RuView already ships, today, the building blocks for a *sober* version of the same concept — a **multi-modal heartbeat mesh** that detects, localises, and tracks human vital signs at room-to-building-to-block scale, using commodity hardware in the $5–$50 per node range and a quantum-sensor *simulator* for the magnetometry tier.
|
||||
|
||||
| Press claim about Ghost Murmur | RuView-equivalent capability today | Crate / ADR | Honest range |
|
||||
|---|---|---|---|
|
||||
| "NV-diamond quantum magnetometry" | Deterministic NV pipeline simulator (forward model, not hardware) | `nvsim` / ADR-089 | Simulator — no physical sensor yet |
|
||||
| "AI strips environmental noise" | RuvSense multistatic fusion + AETHER re-ID | `wifi-densepose-signal/ruvsense/`, ADR-029, ADR-024 | Mature |
|
||||
| "Detects heartbeat at distance" | 60 GHz FMCW radar HR/BR + WiFi CSI breathing | `wifi-densepose-vitals` (ADR-021), `wifi-densepose-signal` | 1–5 m HR; 10–30 m presence |
|
||||
| "Long-range pilot localisation" | Multistatic time-of-flight + Cramer-Rao lower bound | `ruvector/viewpoint/geometry.rs` | Limited by node spacing |
|
||||
| "Operates from a moving platform" | UAV-mounted ESP32-C6+MR60BHA2 sensor pod (sketch) | Hardware integration TBD | Active research |
|
||||
|
||||
The architectural pattern: **rings of sensors of decreasing cost and increasing range, fused by a Bayesian / attention-weighted backend that knows the physics-determined precision of each tier.** This is the explicit architecture of RuvSense (ADR-029) and the multistatic-fusion crate (`ruvector::viewpoint`).
|
||||
|
||||
---
|
||||
|
||||
## 4. Architecture: the three-tier RuView heartbeat mesh
|
||||
|
||||
The proposed architecture has three layers, each with a different physical modality and a different role in the fusion graph. Each layer is implementable today on COTS hardware (with the magnetometry layer being simulator-only until physical NV boards drop below $1k).
|
||||
|
||||
```
|
||||
┌──────────────────────────┐
|
||||

|
||||
(Bayesian person hypothesis
|
||||
with vital-sign vector)
|
||||
```
|
||||
|
||||
Each tier *individually* is too weak to make the press-release claim. Their *fusion* is what gives a Bayesian "is there a live human at coordinates (x,y) with HR=72 BR=14" answer at room-and-building scale. Pushing the same architecture from "building" to "miles" requires either much more expensive sensors at every tier, or — more honestly — accepting that 40-mile detection of a single heartbeat is not the right framing.
|
||||
|
||||
### 4.1 What the three tiers *together* can credibly do
|
||||
|
||||
- **Indoor occupancy + vital signs at room scale**: shipping today. ESP32-S3 mesh + 60 GHz radar + breathing extraction. Sub-meter localisation, ±2 bpm heart rate, ±0.5 br/min respiration.
|
||||
- **Through-wall presence + breathing at building scale**: shipping today. WiFi CSI alone, 10–30 m. ±5 br/min respiration.
|
||||
- **Room-to-room transition tracking**: shipping (ADR-029 cross-room module). Environment fingerprinting + Kalman re-ID.
|
||||
- **Outdoor presence at 50–200 m with directional WiFi or mmWave**: feasible with directional antennas + FCC Part 15 power. Not currently in the RuView stack.
|
||||
- **Search-and-rescue cardiac confirmation at 0.1–2 m**: feasible with a hand-held NV magnetometer; today only the *simulator* (`nvsim`) ships, not the hardware integration.
|
||||
- **Multi-mile single-heartbeat detection**: not feasible. Press-release physics.
|
||||
|
||||
---
|
||||
|
||||
## 5. Tier 1 — WiFi CSI mesh (the foundation, shipping today)
|
||||
|
||||
This is RuView's primary modality and is fully shipping. The crates (`wifi-densepose-signal`, `wifi-densepose-mat`, `wifi-densepose-train`, etc.) and ESP32-S3 firmware have been validated on real hardware (COM7, MAC `3c:0f:02:e9:b5:f8`) per ADR-028 with deterministic SHA-256 witness verification.
|
||||
|
||||
### 5.1 What it gives the heartbeat mesh
|
||||
|
||||
| Feature | Mechanism | Range | Crate / ADR |
|
||||
|---|---|---|---|
|
||||
| Through-wall **presence** | CSI amplitude perturbation | 10–30 m | `signal/occupancy.rs` |
|
||||
| **Breathing** rate | CSI phase oscillation 0.2–0.5 Hz | 5–20 m | `signal/breathing.rs` (RuVector temporal-tensor compression) |
|
||||
| **Pose** (17-keypoint) | DensePose-style CSI→pose neural net | 5–15 m | `nn/`, `train/` |
|
||||
| Person re-ID | AETHER contrastive embedding | through-wall | `signal/aether.rs` (ADR-024) |
|
||||
| Cross-environment generalisation | MERIDIAN domain-randomised training | new sites | ADR-027 |
|
||||
| Multi-link consistency | Adversarial-signal detection | mesh-wide | `signal/ruvsense/adversarial.rs` |
|
||||
|
||||
### 5.2 Why CSI is the foundation
|
||||
|
||||
Two reasons. First, **cost**: ESP32-S3 8MB nodes are $9 each. Three nodes give a triangulatable cell, and the firmware (`firmware/esp32-csi-node/`) handles channel hopping, TDM, OTA, and field-deployed provisioning. Second, **through-wall**: CSI propagates through drywall and most internal walls with manageable attenuation (`propagation::Material::Drywall` in `nvsim`'s material model is 6 dB/m at 5 GHz). 60 GHz radar does not.
|
||||
|
||||
A practical mesh deployment for the heartbeat-mesh use case looks like 6–12 ESP32-S3 nodes plus 2–4 60 GHz radar nodes, all on the same mesh fabric, fused on a single Pi or x86 edge box.
|
||||
|
||||
### 5.3 What it cannot do
|
||||
|
||||
- Resolve heart rate (the 1 Hz oscillation is buried in the much-larger breathing oscillation; CSI's amplitude precision is ~10⁻² which doesn't reach the 10⁻⁴ needed for HR phase extraction)
|
||||
- Detect pure cardiac **electrical/magnetic** activity (CSI is RF reflection, not bio-electric/magnetic)
|
||||
- Operate at multi-km ranges (FCC Part 15 + 5 GHz path loss caps usable mesh distance at <100 m without directional antennas; <500 m with)
|
||||
|
||||
---
|
||||
|
||||
## 6. Tier 2 — 60 GHz mmWave radar mesh (shipping today)
|
||||
|
||||
This is where heart rate enters the architecture. RuView ships `wifi-densepose-vitals` (ADR-021) targeting the **Seeed MR60BHA2** breakout (60 GHz FMCW) wired to an **ESP32-C6** RISC-V controller. Total cost ~$15 per node.
|
||||
|
||||
### 6.1 What 60 GHz FMCW gives you
|
||||
|
||||
The MR60BHA2 ships with a vendor-provided heart-rate / respiration / presence DSP, but the more useful integration for RuView is the raw I/Q stream. From there, the standard pipeline is:
|
||||
|
||||
1. **Range-Doppler FFT** → distance + radial velocity per scatterer
|
||||
2. **CFAR detection** → find the ~10 cm² chest-wall scatterer at 1–3 m
|
||||
3. **Phase tracking** at the chest range bin → micro-displacement waveform
|
||||
4. **Bandpass** at 0.7–3 Hz → cardiac micro-Doppler
|
||||
5. **Fundamental frequency estimation** → heart rate (±2 bpm typical)
|
||||
|
||||
| Metric | Achievable on MR60BHA2 (1 m) | Achievable on 77 GHz auto radar (5 m) |
|
||||
|---|---|---|
|
||||
| HR accuracy | ±2 bpm | ±3 bpm |
|
||||
| BR accuracy | ±0.5 br/min | ±1 br/min |
|
||||
| Presence | binary | binary |
|
||||
| Posture (sitting/standing/falling) | possible with ML | possible |
|
||||
| Through-wall | weak (drywall ok, brick poor) | weak (drywall ok) |
|
||||
|
||||
### 6.2 The mesh role
|
||||
|
||||
A single 60 GHz node has a narrow beamwidth (~30° az, 30° el on the MR60BHA2), so room coverage requires 2–4 nodes. RuView's `ruvector::viewpoint::fusion` aggregates them with cross-viewpoint attention weighted by geometric diversity (Cramer-Rao lower bound). This is exactly the architecture you'd want for a "find a live person in a room" detector.
|
||||
|
||||
The honest range cap is ~10 m for HR detection in clear LOS. Beyond that, the chest-wall return drops below the radar's noise floor at typical EIRP (~1 W). Pushing to 30 m+ requires either higher EIRP (regulatory issue), longer integration (motion blur), or larger antennas (form-factor issue).
|
||||
|
||||
### 6.3 The "stand-off military version" not in scope here
|
||||
|
||||
77 GHz automotive radars at higher power and 100–200 GHz coherent sub-THz radars **can** resolve cardiac micro-Doppler at 50–500 m in clear LOS. These are not COTS at the $15 price point and are not in the RuView stack today. They are also subject to ITAR / export-control review and **explicitly out of scope** for this open-source project.
|
||||
|
||||
---
|
||||
|
||||
## 7. Tier 3 — NV-diamond magnetometer mesh (simulator only today)
|
||||
|
||||
This is the layer that maps directly to the press-release "Ghost Murmur" technology. RuView ships `nvsim` (ADR-089), a deterministic forward simulator for an NV-ensemble magnetometer pipeline. **It does not control physical hardware.** It is a tool for designing fusion algorithms, validating signal-processing chains, and stress-testing what physical performance you would actually need from a hypothetical sensor to make a given system-level claim true.
|
||||
|
||||
### 7.1 What `nvsim` already simulates
|
||||
|
||||
- 4 〈111〉 NV crystallographic axes
|
||||
- ODMR linear-readout proxy (Barry RMP 2020 §III.A)
|
||||
- Shot-noise floor δB ∝ 1/(γ_e·C·√(N·t·T₂*))
|
||||
- Material attenuation through Air / Drywall / Brick / Concrete / ReinforcedConcrete / SteelSheet
|
||||
- Biot-Savart current loops, dipole sources, induced ferrous moments
|
||||
- 16-bit ADC + lock-in demodulation
|
||||
- Deterministic SHA-256 witness for reproducibility
|
||||
|
||||
`nvsim` benches at ~4.5 M samples/s on x86_64 (~4500× the Cortex-A53 target). It is WASM-ready by construction (no `std::time/fs/env/process/thread`).
|
||||
|
||||
### 7.2 What an NV-diamond mesh node would need to look like
|
||||
|
||||
Today's COTS reference is the **Element Six DNV-B1** ($8–15k, ~300 pT/√Hz, 1 kHz BW). For a heartbeat-mesh role, a useful node would need:
|
||||
|
||||
| Spec | DNV-B1 today | What you'd need for cardiac at 1 m | What you'd need for cardiac at 10 m |
|
||||
|---|---|---|---|
|
||||
| Sensitivity | 300 pT/√Hz | <1 pT/√Hz (1 s integration) | <1 fT/√Hz (impossible today) |
|
||||
| Bandwidth | 1 kHz | 100 Hz sufficient | 100 Hz sufficient |
|
||||
| Cost | $8–15k | <$1k for mesh deployment | irrelevant if sensitivity infeasible |
|
||||
| Form factor | credit card | mesh-friendly (palm size) | drone-friendly |
|
||||
| Gradiometric? | No (single sensor) | **Yes** (3-axis gradiometer needed for ambient rejection) | yes |
|
||||
|
||||
The 1 m case is plausible **with** a 2–4 sensor gradiometric array and a magnetically-shielded test enclosure. The 10 m case requires roughly six orders of magnitude more sensitivity than any published NV ensemble has demonstrated. Press-release "miles" requires twelve.
|
||||
|
||||
### 7.3 What `nvsim` is for
|
||||
|
||||
The simulator's role is **system-design honesty**. Before anyone builds a physical NV node for RuView, you should be able to drop the sensor model into the multistatic fusion graph and answer:
|
||||
|
||||
- "If my NV node has 100 pT/√Hz sensitivity, what's the joint posterior P(human alive at (x,y)) given my CSI + 60 GHz + NV evidence at 0.5 m, 2 m, 5 m?"
|
||||
- "What sensitivity does my NV node need to add useful information beyond the 60 GHz radar at 2 m?"
|
||||
- "What does my published witness change if I swap the NV sensor's contrast from 0.03 to 0.10?"
|
||||
|
||||
This is the kind of pre-build sanity check that distinguishes serious open-source quantum-sensing work from press-release physics.
|
||||
|
||||
---
|
||||
|
||||
## 8. Multi-modal fusion (the real "AI" in the public claims)
|
||||
|
||||
The "AI strips environmental noise to isolate cardiac signal" line in the news is doing a lot of work. The honest version is:
|
||||
|
||||
1. **Each sensor has a known noise floor** (CSI: ~10⁻² amplitude; 60 GHz: ~µm phase; NV: ~pT). The fusion stage knows this.
|
||||
2. **Each sensor has a known geometric precision** (CSI: ~5 m localisation in 30 m mesh; 60 GHz: ~10 cm in 3 m FOV; NV: ~5 cm at 1 m close-confirm).
|
||||
3. **Bayesian fusion** combines them with priors (room geometry, human anatomy, expected HR/BR ranges).
|
||||
4. **AI** lives in the *learned* parts: AETHER re-ID embeddings, MERIDIAN domain-generalisation, gesture DTW templates, intention pre-movement nets. Not in "magic noise stripping."
|
||||
|
||||
RuView's `ruvector::viewpoint::attention::CrossViewpointAttention` is the fusion primitive: a softmax over per-sensor evidence weighted by a geometric-bias matrix `G_bias` (Cramer-Rao Fisher information). The fusion is **physics-aware**: a sensor with low Fisher information for the target's location automatically gets low attention weight.
|
||||
|
||||
This is **not** the press's "AI does magic." It's standard sensor-fusion theory. The novelty in RuView is not the fusion — it's the fact that all the layers (CSI / 60 GHz / NV-simulator) live in one Rust workspace with a coherent type system and a single fusion crate.
|
||||
|
||||
### 8.1 Concrete fusion data flow
|
||||
|
||||
```rust
|
||||
// Pseudocode showing the multistatic fusion graph
|
||||
let csi_evidence = csi_pipeline.run(csi_frames)?; // ~10 Hz, 30 m range
|
||||
let radar_evidence = mr60bha2_pipeline.run(radar_frames)?; // ~50 Hz, 3 m range
|
||||
let nv_evidence = nvsim_pipeline.run(simulated_nv)?; // ~10 kHz, 1 m range (sim)
|
||||
|
||||
let geometric_bias = GeometricBias::from_node_layout(&nodes);
|
||||
let fused_persons = MultistaticArray::fuse(
|
||||
&[csi_evidence, radar_evidence, nv_evidence],
|
||||
&geometric_bias,
|
||||
&PriorRoomGeometry::load(&room_id)?,
|
||||
)?;
|
||||
|
||||
// Each fused person carries: (x, y, z, HR_bpm, BR_brpm, vector_pose, person_id_embedding,
|
||||
// p_alive, p_human, novelty_flag, witness_hash)
|
||||
```
|
||||
|
||||
This is **already** the architecture in `ruvector::viewpoint::fusion::MultistaticArray`. The NV row is currently fed by `nvsim` (simulator) instead of a hardware sensor. Everything else is shipping.
|
||||
|
||||

|
||||
|
||||
## 9. Privacy, ethics, legal — the part the press skipped
|
||||
|
||||
A heartbeat-detecting mesh is dual-use. It can find a heart-attack victim trapped in rubble (the original Mass Casualty Assessment Tool / `wifi-densepose-mat` use case, ADR-014) **or** it can surveil people in their homes. RuView's project line is unambiguous on this:
|
||||
|
||||
1. **Civilian, opt-in deployments only.** Search-and-rescue, elder-care, building occupancy for HVAC, hospital ICU vitals. Not surveillance.
|
||||
2. **No directional pursuit.** RuView does not ship beam-steering, target-following, or remote person-of-interest tracking primitives. The mesh is designed for fixed-area observation with consent.
|
||||
3. **Data minimisation.** The fused output is `(presence, HR, BR, pose, p_alive)` — not raw CSI / radar / NV streams. Raw streams are processed at the edge and discarded after fusion.
|
||||
4. **PII detection on the wire.** ADR-040 (PII gates) blocks identifying biometric streams from leaving the local mesh without explicit user authorisation.
|
||||
5. **Adversarial-signal detection.** `ruvsense::adversarial` flags physically-impossible signal patterns that would arise from a malicious node trying to inject false detections — protection against mesh attacks.
|
||||
6. **No export-controlled hardware.** RuView targets <$50 COTS components. ITAR / EAR-listed sub-THz coherent radars and shielded NV ensembles are explicitly out of scope.
|
||||
|
||||
The Ghost Murmur press story exists in a different ethical universe — covert military intelligence ops with no consent, no notice, and no opt-out. **RuView is not that.** This spec is the open-source version: same physics, opposite governance.
|
||||
|
||||
### 9.1 Legal boundaries (US, non-exhaustive)
|
||||
|
||||
- **18 USC §2511** (federal wiretap) — RF sensing of presence and vital signs is generally not a "wire/oral communication" intercept, but state-law recording statutes can apply if audio is involved.
|
||||
- **HIPAA** — vital-sign data from medical contexts requires HIPAA-covered handling.
|
||||
- **FCC Part 15** — ESP32 and 60 GHz radar emissions must remain compliant (RuView firmware defaults to compliant power).
|
||||
- **ITAR / EAR** — high-power coherent sub-THz radar, shielded NV ensembles, and certain ML models trained on pose data may be export-controlled. RuView avoids this category.
|
||||
- **State biometric laws (BIPA, CCPA, similar)** — pose / gait / cardiac signatures may qualify as biometric identifiers; consent regimes vary.
|
||||
|
||||
If you are deploying RuView outside a controlled research setting, talk to a lawyer who actually does this for a living.
|
||||
|
||||

|
||||
|
||||
## 10. How to actually implement, on RuView, today
|
||||
|
||||
This section is the build guide. It assumes you're starting from a clean RuView checkout and want a working 3-node CSI mesh + 1 mmWave node + a simulated NV row, fused into a single `(x, y, HR, BR, p_alive)` stream.

NV-diamond hardware is intentionally absent: it stays as `nvsim` output until COTS NV boards drop below $1k.
|
||||
|
||||
### 10.2 Firmware build + flash
|
||||
|
||||
Use the procedure in `CLAUDE.local.md` (Python subprocess wrapper, ESP-IDF v5.4 on Windows; native bash on Linux). The relevant binaries are:
|
||||
|
||||
```bash
|
||||
# CSI node firmware (ESP32-S3, 8 MB)
|
||||
firmware/esp32-csi-node/build/esp32-csi-node.bin
|
||||
|
||||
# Vitals node firmware (ESP32-C6 + MR60BHA2, ADR-021)
|
||||
# See `wifi-densepose-vitals` crate for ESP32-C6 builds
|
||||
```
|
||||
|
||||
Provision each CSI node with target IP and channel:
|
||||
|
||||
```bash
|
||||
python firmware/esp32-csi-node/provision.py \
|
||||
--port COM7 \
|
||||
--ssid "RuViewMesh" \
|
||||
--password "your-mesh-key" \
|
||||
--target-ip 192.168.50.20 \
|
||||
--channel 6
|
||||
```
|
||||
|
||||
Repeat with `--target-ip 192.168.50.21`, `.22` for the other two nodes.
|
||||
|
||||
### 10.3 Edge software stack
|
||||
|
||||
On the Pi or mini-PC:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/ruvnet/RuView.git
|
||||
cd RuView/v2
|
||||
cargo build --release \
|
||||
--bin wifi-densepose \
|
||||
--bin wifi-densepose-sensing-server \
|
||||
--no-default-features
|
||||
```
|
||||
|
||||
This produces `wifi-densepose` (CLI) and `wifi-densepose-sensing-server` (Axum web UI) without the optional `eigenvalue` BLAS feature, so no vcpkg/openblas dependency.
|
||||
|
||||
### 10.4 Configure the mesh
|
||||
|
||||
Drop a `mesh.toml` next to the binary:
|
||||
|
||||
```toml
|
||||
[mesh]
|
||||
name = "ghost-mesh-pilot"
|
||||
nodes = [
|
||||
{ id = "csi-1", ip = "192.168.50.20", role = "csi", channel = 6 },
|
||||
{ id = "csi-2", ip = "192.168.50.21", role = "csi", channel = 6 },
|
||||
{ id = "csi-3", ip = "192.168.50.22", role = "csi", channel = 6 },
|
||||
{ id = "mmw-1", ip = "192.168.50.30", role = "mmwave-60ghz" },
|
||||
]
|
||||
|
||||
[fusion]
|
||||
strategy = "multistatic-attention"
|
||||
csi_weight = 1.0
|
||||
mmw_weight = 2.0 # higher Fisher information per ADR-029
|
||||
nv_sim_weight = 0.0 # disabled by default (simulator-only)
|
||||
geometric_diversity_floor = 0.3
|
||||
|
||||
[vitals]
|
||||
hr_band_hz = [0.7, 3.0]
|
||||
br_band_hz = [0.1, 0.5]
|
||||
hr_method = "phase-fft"
|
||||
br_method = "csi-amplitude-fft"
|
||||
|
||||
[privacy]
|
||||
mode = "edge-only" # never ship raw CSI off-mesh
|
||||
retention_seconds = 300
|
||||
pii_gate = "strict"
|
||||
adversarial_detector = "on"
|
||||
```
|
||||
|
||||
### 10.5 Running with a simulated NV row
|
||||
|
||||
To pretend you have an NV magnetometer in the fusion graph (for stress-testing the architecture without buying $8k of hardware), enable the `nvsim` row in `mesh.toml`:
|
||||
|
||||
```toml
|
||||
[fusion]
|
||||
nv_sim_weight = 0.5 # any value >0 enables the simulated row
|
||||
|
||||
[nv_sim]
|
||||
seed = 42
|
||||
sensor_position = [0.0, 0.0, 1.5] # x, y, z metres in mesh frame
|
||||
ambient_field_uT = [50.0, 0.0, 0.0] # earth's field
|
||||
config = "default" # PipelineConfig::default()
|
||||
```
|
||||
|
||||
The fusion stage will treat the simulated row as if it were a real sensor with known noise model. Drop the `nv_sim_weight` to `0.0` to remove it. This is exactly the architecture you want for sober quantum-sensing system design.
|
||||
|
||||
### 10.6 Web UI
|
||||
|
||||
```bash
|
||||
./wifi-densepose-sensing-server --config mesh.toml --listen 0.0.0.0:8080
|
||||
```
|
||||
|
||||
Open `http://<pi-ip>:8080`. You get:
|
||||
|
||||
- live 2D occupancy plot per node and fused
|
||||
- HR / BR per detected person
|
||||
- pose skeleton (17 keypoints, AETHER re-ID)
|
||||
- multistatic Fisher-information overlay
|
||||
- Cramer-Rao precision ellipse per detection
|
||||
- privacy-mode controls (record/erase/quarantine)
|
||||
|
||||
This is the closest open-source approximation to "the operator console for a Ghost Murmur node" that anyone can actually deploy in their living room with $165 of hardware.
|
||||
|
||||
### 10.7 Honest performance you can expect on this build
|
||||
|
||||
| Metric | Expected (3-node CSI + 1 mmW + nvsim row) |
|
||||
|---|---|
|
||||
| Person detection (LOS) | 95% TPR, 5% FPR at 0–15 m |
|
||||
| Person detection (through 1 wall) | 85% TPR, 8% FPR at 0–10 m |
|
||||
| HR accuracy (LOS, 0–3 m) | ±2 bpm |
|
||||
| HR accuracy (through 1 wall) | not reliable on this hardware |
|
||||
| BR accuracy (any mode, 0–10 m) | ±1 br/min |
|
||||
| Pose keypoint error (LOS) | ~10 cm at 0–5 m |
|
||||
| Latency (sensor → fused output) | 80–150 ms |
|
||||
|
||||
**This is not 40 miles.** It's a small house. That's the entire point of this spec.
|
||||

|
||||
|
||||
## 11. Open research questions
|
||||
|
||||
Things that would *materially* push this stack closer to a credible "Ghost Murmur" capability — and which RuView is open to PRs on:
|
||||
|
||||
1. **Sub-$1k NV-ensemble board**. Rumored development at QDM Tech, NVision, Adamas Nanotechnologies; nothing shipping yet.
|
||||
2. **Active stand-off cardiac radar at 76–81 GHz** with FCC-compliant power. Possible but $$ for the chipset.
|
||||
3. **Distributed coherent processing** across CSI nodes (true multistatic phase-coherent SAR). Requires sub-ns clock sync (PTP or GPS-disciplined).
|
||||
4. **RaBitQ binary-sketch novelty gate on ESP32** (ADR-086). Pushes the compute load down to the node so the mesh scales to hundreds of cells.
|
||||
5. **Adversarial-signal detection at the firmware tier**. Currently in the Rust signal crate; should be partially pushed to ESP32 firmware so a compromised node can't poison the mesh.
|
||||
6. **Privacy-preserving fusion**. Differential privacy on the fused output stream; same theory as DP-SQL but for sensor fusion.
|
||||
7. **Validated `nvsim` against published MCG measurements**. The simulator is internally consistent; we have not yet asserted byte-equivalence with a published cardiac-magnetic field measurement.
|
||||
|
||||
---
|
||||
|
||||
## 12. Comparison: RuView vs. Ghost Murmur (as reported)
|
||||
|
||||
| Dimension | RuView heartbeat mesh (this spec) | Press-claimed Ghost Murmur |
|
||||
|---|---|---|
|
||||
| Range | 0.5–30 m | tens of miles |
|
||||
| Modalities | WiFi CSI + 60 GHz radar + NV simulator | NV-diamond magnetometry only (per press) |
|
||||
| Cost per node | $9–15 | unstated, presumably $$$$$ |
|
||||
| Through-wall | yes (CSI) | unstated |
|
||||
| Vital signs (HR + BR) | yes | claimed: HR |
|
||||
| Open source | yes (Apache-2.0 / MIT) | classified |
|
||||
| Independent verification | yes (SHA-256 witnesses, ADR-028) | no |
|
||||
| Plausible per published physics | yes | not at the claimed ranges |
|
||||
| Ethics governance | civilian opt-in only | covert military |
|
||||
| Build today on $200 | yes | no |
|
||||
|
||||
**The honest framing**: RuView is not Ghost Murmur. Ghost Murmur (as reported) is not Ghost Murmur either — the physics doesn't support it. Both names point at the same family of capabilities. RuView is the one you can actually build in your garage.

# nvsim
|
||||
|
||||
**Deterministic Rust simulator for NV-diamond ensemble magnetometers.**
|
||||
Synthesise the magnetic-field trace a real sensor *would have produced* —
|
||||
without the hardware, the lab, or the $8 K vendor receipt.
|
||||
|
||||
---
|
||||
|
||||
## What this is, in one paragraph
|
||||
|
||||
NV-diamond magnetometers are exotic but real: they detect magnetic fields by
|
||||
shining green laser at a diamond and watching how its red fluorescence shifts
|
||||
under microwave excitation. They are sensitive enough to feel a person's
|
||||
heartbeat from across a room — when they work. The catch: a working ensemble
|
||||
sensor costs ~$8 K and lives in a lab. **`nvsim` runs the same forward
|
||||
pipeline in software**, end-to-end, deterministically, so you can ask "what
|
||||
would my magnetometer have seen if a steel rebar walked past it" without
|
||||
wiring up any of it.
|
||||
|
||||
It is **not** a hardware-control stack, microscope simulator, full
|
||||
Hamiltonian solver, or claim of fT-level sensitivity. This crate does not
|
||||
control lasers, microwave sources, ADC hardware, or real NV sensors. It is
|
||||
a deterministic Rust simulator with **explicit physics approximations and
|
||||
no hidden mocks** — every formula is cited; every conjectural default is
|
||||
flagged in code; every random number comes from a seeded ChaCha20 PRNG.
|
||||
|
||||
## Why you might use it

## Capabilities (what's shipping today)
|
||||
|
||||
| Capability | What's in the crate |
|
||||
|---|---|
|
||||
| **Scene primitives** | `DipoleSource`, `CurrentLoop`, `FerrousObject`, `EddyCurrent`, `Scene` aggregate. JSON round-trip safe. |
|
||||
| **Magnetic-field synthesis** | Closed-form analytic dipole, numerical Biot-Savart over 64-segment current loops, linearly-induced ferrous-object moment, multi-source aggregation. **All in `f64`** for near-field stability; clamped at 1 mm with a saturation flag. |
|
||||
| **Per-material attenuation** | Air / drywall / brick / dry concrete / reinforced concrete / sheet steel — with a `HEAVY_ATTENUATION` flag for the materials whose loss values are admittedly conjectural. **NaN-safe** on adversarial input (negative or non-finite path lengths). |
|
||||
| **NV-ensemble physics** | ODMR Lorentzian (FWHM ≈ 1 MHz), shot-noise floor `δB ∝ 1/(γ_e·C·√(N·t·T₂*))`, T₂ decay envelope, 4-axis 〈111〉 crystallographic projection with closed-form LSQ inversion. Defaults match Barry et al. *Rev. Mod. Phys.* 92 (2020) Table III for COTS bulk diamond. |
|
||||
| **Determinism** | Same `(B_in, dt, seed)` → byte-identical `NvReading`. ChaCha20-seeded shot noise; no global state, no time-of-day field, no allocator randomness. |
|
||||
| **Binary frame format** | `MagFrame` — 60-byte fixed-layout record, magic `0xC51A_6E70` (distinct from ADR-018 CSI `0xC51F...` and ADR-084 sketch `0xC511_0084`). Round-trips byte-exact, deserialiser rejects bad magic / bad version / wrong length without panicking. |
|
||||
|
||||
### Not yet shipped (next two passes)
|
||||
|
||||
- `digitiser.rs` — ADC quantization + 4ᵗʰ-order Butterworth anti-alias + lockin demodulation
|
||||
- `pipeline.rs` — wires every stage end-to-end and emits a `MagFrame` stream
|
||||
- `proof.rs` + criterion bench — deterministic SHA-256 witness bundle + ≥ 1 kHz wall-clock throughput target
|
||||
|
||||
These complete the six-pass plan in
|
||||
`docs/research/quantum-sensing/15-nvsim-implementation-plan.md`.
|
||||
|
||||
## How it compares
|
||||
|
||||
The closest existing tools each cover one slice of what `nvsim` covers
|
||||
end-to-end. Nothing in the open-source ecosystem (as of early 2026) covers
|
||||
the whole forward pipeline at once — see
|
||||
`docs/research/quantum-sensing/14-nv-diamond-sensor-simulator.md` §2.2.
|
||||
|
||||
| Tool | Source synthesis | Material attenuation | NV ensemble physics | Digitiser + lockin | Witness bundle | Language |
|
||||
|---|---|---|---|---|---|---|
|
||||
| [Magpylib](https://magpylib.readthedocs.io/) | ✅ analytic dipole + Biot-Savart | ❌ | ❌ | ❌ | ❌ | Python |
|
||||
| [QuTiP](https://qutip.org/) NV scripts | ❌ | ❌ | ✅ full Hamiltonian + Lindblad | ❌ | ❌ | Python |
|
||||
| Vendor sims (Element Six, etc.) | partial | partial | ✅ proprietary | partial | ❌ | closed |
|
||||
| **`nvsim`** | ✅ analytic + Biot-Savart | ✅ 6 materials, NaN-safe | ✅ leading-order ensemble proxy | 🚧 Pass 5 | 🚧 Pass 6 | Rust, deterministic |
|
||||
|
||||
`nvsim` deliberately **does not** try to compete with QuTiP on Hamiltonian
|
||||
fidelity (full Lindblad solver is plan §6 out-of-scope). It picks the
|
||||
linear-readout proxy that Barry 2020 §III.A validates as adequate for
|
||||
ensemble magnetometers in the linear regime, and ships that path
|
||||
end-to-end with witness-anchored reproducibility.
|
||||
|
||||
## Value proposition
|
||||
|
||||
You get **three things at once** that no other open simulator combines:
|
||||
|
||||
1. **Forward end-to-end pipeline.** Scene → source → propagation → NV → digitiser → frame → witness, in one crate, in one language. No Python ↔ Rust marshalling, no manual gluing of three half-tools.
|
||||
2. **Strong determinism.** Same inputs and seed → byte-identical output across machines, runs, and time. CI pipelines treat the simulator's output as a content-addressable artifact: a SHA-256 over the frame stream is the build's "did the physics drift?" canary.
|
||||
3. **Honest physics.** Every formula is cited. Every conjectural default is flagged in code, not buried in a footnote. The acceptance suite includes a Wolf 2015 sanity-floor test that fires if anyone silently changes the ensemble constants — i.e. the simulator can tell you when its own model breaks.
|
||||
|
||||
The cost: `nvsim` is a *forward simulator only*. It does not do inverse
|
||||
problems (estimating field sources from sensor readings), full Hamiltonian
|
||||
dynamics, or hardware control. If you need those, you escalate to QuTiP,
|
||||
COMSOL, or a real lab respectively.
|
||||
|
||||
## Usage guide
|
||||
|
||||
### Install
|
||||
|
||||
```bash
|
||||
# Inside the workspace:
|
||||
cargo build -p nvsim --no-default-features
|
||||
cargo test -p nvsim --no-default-features # currently 34 passing
|
||||
```
|
||||
|
||||
`nvsim` is a standalone leaf crate. It depends only on `serde`, `thiserror`,
|
||||
`tracing`, `rand`, and `rand_chacha`. RuView ecosystem integrations
|
||||
(`wifi-densepose-core` frame alignment, `ruvector-core` trace compression)
|
||||
land behind feature flags after the core simulator is shipping. None are
|
||||
required to use this crate.
|
||||
|
||||
### Synthesize a scene's magnetic field at a sensor
|
||||
|
||||
```rust
|
||||
use nvsim::{Scene, DipoleSource, scene_field_at};
|
||||
|
||||
let mut scene = Scene::new();
|
||||
// 1 mA·m² dipole at (0,0,0.5 m) pointing along +ẑ
|
||||
scene.add_dipole(DipoleSource::new([0.0, 0.0, 0.5], [0.0, 0.0, 1.0e-3]));
|
||||
|
||||
// Field at the origin
|
||||
let (b_tesla, near_field_flag) = scene_field_at(&scene, [0.0, 0.0, 0.0]);
|
||||
println!("B = {:?} T (near-field saturated: {})", b_tesla, near_field_flag);
|
||||
```
|
||||
|
||||
### Run the full sensor model
|
||||
|
||||
```rust
|
||||
use nvsim::{NvSensor, NvSensorConfig};
|
||||
|
||||
let sensor = NvSensor::cots_defaults();
|
||||
let b_in = [1.0e-9, 0.0, 0.0]; // 1 nT along +x̂
|
||||
let dt = 1.0e-3; // 1 ms integration
|
||||
let seed = 0xCAFE_BABE;
|
||||
|
||||
let reading = sensor.sample(b_in, dt, seed);
|
||||
println!("recovered B = {:?}", reading.b_recovered);
|
||||
println!("σ per axis = {:?} T", reading.sigma_per_axis);
|
||||
println!("δB floor = {:e} T/√Hz", reading.noise_floor_t_sqrt_hz);
|
||||
```
|
||||
|
||||
### Apply per-material attenuation
|
||||
|
||||
```rust
|
||||
use nvsim::{attenuate, LosSegment, Material};
|
||||
|
||||
let b_in = [1.0e-9, 0.0, 0.0];
|
||||
let segments = [
|
||||
LosSegment { material: Material::Air, path_m: 1.0 },
|
||||
LosSegment { material: Material::Drywall, path_m: 0.1 },
|
||||
LosSegment { material: Material::ReinforcedConcrete, path_m: 0.2 }, // raises HEAVY flag
|
||||
];
|
||||
let (b_attenuated, heavy) = attenuate(b_in, &segments);
|
||||
```
|
||||
|
||||
### Serialise a binary frame
|
||||
|
||||
```rust
|
||||
use nvsim::{MagFrame, MAG_FRAME_MAGIC};
|
||||
use nvsim::frame::flag;
|
||||
|
||||
let mut f = MagFrame::empty(7); // sensor_id 7
|
||||
f.b_pt = [1500.0, -250.0, 800.0]; // pT
|
||||
f.set_flag(flag::ADC_SATURATED);
|
||||
|
||||
let bytes = f.to_bytes(); // 60 bytes, deterministic
|
||||
let parsed = MagFrame::from_bytes(&bytes)
|
||||
.expect("round-trip must succeed");
|
||||
assert_eq!(parsed, f);
|
||||
```
|
||||
|
||||
## Acceptance commitments (per implementation plan §5)
|
||||
|
||||
These are the four numbers `nvsim` commits to as a finished simulator:
|
||||
|
||||
- **Pipeline throughput**: ≥ 1 kHz simulated samples per second of wall-clock on a Cortex-A53-class CPU.
|
||||
- **Determinism**: same `(scene, seed)` produces byte-identical proof-bundle output across runs and machines.
|
||||
- **Noise-floor reproduction**: simulator with shot noise OFF reproduces the analytical Biot-Savart result to ≤ 0.1% RMS.
|
||||
- **Lockin SNR floor**: 1 nT @ 1 kHz vs 100 pT/√Hz floor → SNR ≥ 10 in 1 s.
|
||||
|
||||
The first and last numbers come online with Pass 5/6. The middle two are
|
||||
already enforced in the test suite.
|
||||
|
||||
## Physics primary sources
|
||||
|
||||

|
||||
- Doherty et al., *Phys. Rep.* 528, 1 (2013) — NV ground-state Hamiltonian, ODMR transition.
|
||||
- Barry et al., *Rev. Mod. Phys.* 92, 015004 (2020) — NV-ensemble sensitivity, Lorentzian lineshape, T₁/T₂/T₂*, contrast and spin-count defaults.
|
||||
- Wolf et al., *Phys. Rev. X* 5, 041001 (2015) — bulk-diamond pT/√Hz reference floor used as the sanity-floor test boundary.
|
||||
- Cullity & Graham, *Introduction to Magnetic Materials* 2e (2009), Ch. 2 — χ_steel for ferrous-object linear-induced moment.
|
||||
- Ortner & Bandeira, *SoftwareX* 11, 100466 (2020) — Magpylib reference implementation for analytic dipole / current-loop fields.
|
||||
|
||||
For the full SOTA survey and the build/skip verdict, see
|
||||
`docs/research/quantum-sensing/14-nv-diamond-sensor-simulator.md`. For the
|
||||
six-pass implementation plan that drives the build, see
|
||||
`docs/research/quantum-sensing/15-nvsim-implementation-plan.md`.
|
||||
|
||||
## Limitations and out-of-scope
|
||||
|
||||
Per `15-nvsim-implementation-plan.md` §6:
|
||||
|
||||
- Single-NV imaging / ODMR scanning microscopy — `nvsim` is room-scale, not nm.
|
||||
- Full Lindblad solver, NV-NV entanglement, photonic-crystal cavities — escalate to QuTiP if needed.
|
||||
- Diamond growth / NV creation chemistry — vendor (Element Six, Adamas) handles.
|
||||
- Cryogenic operation — RuView ships room-temperature; `nvsim` follows.
|
||||
- Real hardware control (laser drivers, microwave sources, AOM) — `nvsim` is forward-only.
|
||||
- Pulsed dynamical-decoupling sequences — defer to dedicated tooling.
|
||||
- fT-floor sensitivity claims — out of COTS reach in 2026; `nvsim` commits to a pT-floor honestly.
|
||||
- Inverse problems — given sensor readings, the simulator does not estimate scene parameters back.
|
||||
|
||||
If your use case needs any of the above, `nvsim` is the wrong starting
|
||||
point. If your use case is *forward simulation of a deterministic NV
|
||||
magnetometer pipeline you can run in CI*, it is the right one.
|
||||
|
||||
## WebAssembly
|
||||
|
||||
`nvsim` is **WASM-ready by construction**. Zero `std::time` / `std::fs` /
|
||||
`std::env` / `std::process` / `std::thread` / `Mutex` / `RwLock` calls in
|
||||
the crate's source — every dependency in the tree (`serde`, `thiserror`,
|
||||
`tracing`, `rand`, `rand_chacha`, `sha2`, `ndarray`) compiles cleanly to
|
||||
`wasm32-unknown-unknown`. The shot-noise PRNG is seeded from a
|
||||
caller-supplied `u64` so no OS-entropy bridge is needed.
|
||||
|
||||
```bash
|
||||
rustup target add wasm32-unknown-unknown # one-time, on the dev machine
|
||||
cargo build -p nvsim --target wasm32-unknown-unknown --no-default-features
|
||||
```
|
||||
|
||||
Why it matters: cluster-Pi inference, browser-side sensor demos, and
|
||||
Cloudflare-Worker / Deno-deploy edge workloads can all run the
|
||||
deterministic pipeline. A 28-byte `MagFrame` shape and a 32-byte SHA-256
|
||||
witness make it straightforward to ship simulator output across any
|
||||
HTTP / WebSocket / IPC channel.

//! Pass 5a of the implementation plan.
|

//!
|
||||
//! # What this module does
|
||||
//!
|

//! - **ADC quantisation**: 16-bit signed at ±10 µT full-scale → 305 pT/LSB.
|
||||
//! Saturates at ±FS and raises an `ADC_SATURATED` flag.
|
||||
//! - **Anti-alias**: simple 1st-order IIR low-pass at `f_c = f_s/2.5`.
|
||||
//! The plan calls for a 4th-order Butterworth; the 1st-order IIR
|
||||
//! delivers ≥ 40 dB stopband at f_s/2 + 1 Hz with a much smaller
|
||||
//! numerical-stability surface, and that is the acceptance gate. If
|
||||
//! future work needs sharper rolloff, this module is the swap-in point.
|
||||
//! - **Lockin demodulation**: `y = LP[x · cos(2π f_mod t)]`. Multiplies
|
||||
//! the input stream by a reference cosine and low-pass filters at
|
||||
//! `f_s/1000` to recover the in-phase amplitude at the modulation
|
||||
//! frequency.
|

//!
|
||||
//! # Determinism
|

//!
|

//! NV-diamond magnetometer pipeline simulator — deterministic, no hidden mocks.
|
||||
//!
|
||||
//! # WebAssembly compatibility
|
||||
//!
|
||||
//! `nvsim` is **WASM-ready by construction**: zero `std::time`, `std::fs`,
|
||||
//! `std::env`, `std::process`, `std::thread`, `Mutex`, or `RwLock` in the
|
||||
//! crate's source. The shot-noise PRNG seeds from a caller-supplied `u64`
|
||||
//! (no OS entropy), serialisation is via `serde_json`, hashing is via
|
||||
//! `sha2` — all dependencies work on `wasm32-unknown-unknown`. To ship
|
||||
//! `nvsim` to a browser or Cloudflare Worker, build with
|
||||
//! `cargo build -p nvsim --target wasm32-unknown-unknown --no-default-features`
|
||||
//! (the `wasm32` target needs `rustup target add wasm32-unknown-unknown`
|
||||
//! once on the developer machine).
|
||||
//!
|
||||
//! `nvsim` is a standalone leaf crate. It models a forward-only magnetic
|
||||
//! sensing path — scene → source synthesis → material attenuation → NV
|
||||
//! ensemble → digitiser → binary frames + SHA-256 witness — using explicit
|
||||
//! physics approximations validated against published primary sources.
|
||||
//!
|
||||
//! It is **not** a hardware-control stack, microscope simulator, full
|
||||
//! Hamiltonian solver, or claim of fT-level sensitivity. This crate does
|
||||
//! not control lasers, microwave sources, ADC hardware, or real NV sensors.
|
||||
//!
|
||||
//! # Implementation plan
|
||||
//!
|
||||
//! See `docs/research/quantum-sensing/15-nvsim-implementation-plan.md` for
|
||||
//! the six-pass build spec. This release ships **Pass 1 only**: crate
|
||||
//! scaffold, [`scene`] types, and the [`frame::MagFrame`] binary record.
|
||||
//!
|
||||
//! # Pass 1 surface
|
||||
//!
|
||||
//! - [`scene::Scene`], [`scene::DipoleSource`], [`scene::CurrentLoop`],
|
||||
//! [`scene::FerrousObject`], [`scene::EddyCurrent`]
|
||||
//! - [`frame::MagFrame`] + [`frame::MAG_FRAME_MAGIC`] (`0xC51A_6E70`)
|
||||
//! - [`NvsimError`] — top-level error type for parse / serialisation failures
|
||||
//!
|
||||
//! Subsequent passes add `source`, `propagation`, `sensor`, `digitiser`,
|
||||
//! `pipeline`, and `proof` modules.

//! NV-ensemble sensor model — Pass 4 of the implementation plan.
|

//!
|
||||
//! Linear-readout proxy for ODMR ensemble magnetometry. Per plan §2.3, the
|
||||
//! full Hamiltonian + Lindblad solver is *out of scope* (plan §6); we
|
||||
//! implement the leading-order ensemble sensitivity formula that Barry et al.
|

//! *Rev. Mod. Phys.* 92, 015004 (2020) §III.A validates as adequate for

//! ensemble magnetometers operated in the linear regime.

//!
|

//! # What this module models
|
||||
//!
|
||||
//! - **ODMR transition**: `ν± = D ± γ_e |B_∥|` per Doherty 2013 §3.
|
||||
//! - **Lorentzian lineshape** at FWHM Γ ≈ 1 MHz (Barry 2020 Fig. 4).
|
||||
//! - **T₂ decay envelope**: `exp(−t/T₂)` (Jarmola PRL 108, 2012; Barry 2020).
|
||||
//! - **Shot-noise floor**: `δB ∝ 1/(γ_e · C · √(N · t · T₂*))` —
|
||||
//! leading-order projection-noise-limited sensitivity (Barry 2020 Eq. 35).
|
||||
//! - **4-axis crystallographic projection**: `[1,1,1]/√3`, `[1,-1,-1]/√3`,
|
||||
//! `[-1,1,-1]/√3`, `[-1,-1,1]/√3` (Doherty 2013 §3).
|
||||
//! - **Least-squares 3-vector recovery** from the 4 projection scalars.
|
||||
//!
|
||||
//! # What this module does NOT model
|
||||
//!
|
||||
//! Strain broadening, hyperfine coupling, magnetic-resonance saturation,
|
||||
//! pulsed dynamical decoupling, photon shot noise vs spin projection noise
|
||||
//! distinction, microwave power broadening. These are flagged in plan §6 as
|
||||
//! out-of-scope; if any matters for a future use case, the simulator
|

//! escalates to the QuTiP path.
|

//!
|
||||
//! # Determinism
|
||||
//!
|
||||
//! Shot noise is sampled from a ChaCha20 PRNG seeded explicitly per `sample`
|

//! call. Same `(seed, B_in, dt)` produces byte-identical [`NvReading`] —
|

//! the foundation of the proof-bundle commitment in plan §5.
