ITU-R P.833-9 vegetation-attenuation model + ESP32-S3 link-budget
solver produce bounded sensing range estimates per frequency and
foliage density. Plus a biomechanics-grounded gait-frequency taxonomy
spanning bears (0.5 Hz) to mice (15 Hz).
Headline ranges (121 dB link budget, 10 dB SNR margin):
freq sparse moderate dense
2.4 GHz 99.6 m 12.0 m 4.1 m
5 GHz 19.9 m 5.2 m 2.1 m
The 2.4 GHz / sparse cell (~100 m) is the practical sweet spot —
10x camera-trap coverage, always-on rather than PIR-triggered.
Honest scope called out explicitly: this is feasibility math, not
field measurements. Animal cooperation, foliage flutter, regulatory
limits, and BSSID-fingerprint degradation in remote forest are all
real follow-up problems.
Vertical applications (10-20 year horizon) catalogued:
- Endangered-species population census
- Wildlife corridor verification
- Invasive-species early warning
- Anti-poaching (human gait well-separated from wildlife)
- Livestock-on-rangeland tracking
- Agricultural pest control
Cross-connects to:
- R5 (saliency is task-specific — per-species classifier needs own
saliency map, same lesson as R12)
- R8 (wildlife sensing wants CSI not RSSI for per-subcarrier shape)
- R9 (fingerprint K-NN primitive transfers to per-individual ID)
- R7 (multi-link consistency for corridor coverage)
Pure-NumPy, no framework deps. ITU model + binary search solver.
Coordination: tick avoided PROGRESS.md to prevent races (horizon-
tracker M3+ track concurrent at the time).

Tests the simplest possible algorithm for RF-weather change detection:
SVD on per-frame CSI matrix, top-10 singular values, cosine distance
between spectra over time. Hypothesis: a synthetic structural
perturbation (15 percent attenuation on 3 top-saliency subcarriers)
should produce a larger spectral shift than natural temporal drift
from operator movement in the same recording.
Result honestly: it does not. The perturbation distance (0.00024) is
*smaller* than the control distance (0.00035) — signal/drift ratio
0.69x. The top-K SVD-spectrum cosine is too coarse to detect
small-magnitude subcarrier-specific structural changes against an
operator-noise background.
Three concrete fixes identified for follow-up ticks:
1. Principal angles between subspaces (PABS), not cosine on singular
values — catches subspace rotations the spectrum misses
2. Per-subcarrier residual analysis after projecting onto baseline
subspace — localises the perturbation
3. Multi-day baseline — knocks down operator-noise floor by 50-100x
Useful cross-validations the negative result produces:
* R5 task-specific saliency (count-task) does not generalise to
structure-detection saliency. Same data, different relevant
features. Publishable distinction.
* R12 is CSI-only territory — RSSI is the trace of the CSI
covariance, so if top-10 SVD-spectrum can't see this, RSSI can't
either. Bounds R8 commercial-enablement story to counting only.
* R7 SVD-spectrum primitive that worked for adversarial detection
fails here at lower perturbation magnitude. Sensitivity does NOT
scale with subtlety — confirms the algorithm is magnitude-dominated.
Long-horizon vision (building structural monitoring, earthquake drift,
HVAC audits, climate-controlled-archive surveillance) preserved in the
research note — the physics is right, the hardware is sufficient,
the deployment story works. Just need PABS + multi-day data.
Coordination note: this tick avoided PROGRESS.md edits entirely
because horizon-tracker is concurrently editing it. Tick-5 summary
written to ticks/tick-5.md (new self-contained convention) so the
08:00 ET final summary can consolidate without conflicts.

* research(R9): RSSI fingerprint K-NN — 2.18x lift (MODERATE); surfaces counting-vs-localization asymmetry
Hypothesis: if temporal proximity correlates with RSSI-feature
proximity in the existing single-session data, RSSI fingerprinting is
viable. If K-NN of each query is random in time, RSSI sequences are
too noisy for fingerprint localization.
Test: 1077 samples, 20-dim RSSI proxy (band-mean across 56
subcarriers), cosine-NN with K=5, measure fraction of K-NN within
plus/minus 60s of each query timestamp. Compare to random baseline.
Result (honest):
5-NN within +/-60s 0.169
Random baseline 0.077
Lift over random 2.18x (verdict: MODERATE)
Per-query stdev 0.183
Below the >=3x STRONG-fingerprint threshold but well above 1x random.
Real signal, but weaker than R8 counting result on the same data.
Important asymmetry surfaced (publishable distinction):
Task RSSI vs CSI retention Verdict
------- ----- -----
Counting 94.82% (R8) RSSI works well
Localization ~2x random (R9) RSSI struggles in this regime
This is consistent with R5's band-spread observation: the count signal
integrates across the band, but localization may require per-subcarrier
shape that the band-mean discards.
Three actionable explanations for the MODERATE result:
1. 20-frame windows (~2s) too short for stable fingerprint while operator
moves — longer windows might lift to 3-4x.
2. Within-room fingerprint space too narrow — multi-room data would
show categorical lift jump (5-10x).
3. Band-mean discards the per-subcarrier shape needed for localization.
Once multi-room data lands (#645), this test should be re-run; if
hypothesis (2) is right, the lift will jump categorically.

* feat(tools/ruview-mcp): M2 — wire real inference via cog health subcommand
ruview_pose_infer and ruview_count_infer now run the cog binary's `health`
subcommand (ADR-100 contract) which performs real Candle forward-pass
inference on a synthetic CSI window and emits a structured health.ok JSON
event containing backend, confidence (pose) or count/confidence/p95_range
(count). The MCP tools parse this event and return typed inference results.
This satisfies the ADR-104 acceptance gate: "ruview_pose_infer returns a
finite output for a synthetic CSI window" when the cog binary is installed.
On machines without the binary, both tools still fail-open with {ok:false,
warn:true} and actionable install hints.
Also updates PROGRESS.md with cross-links: R7 (Stoer-Wagner) and R8
(RSSI-only 94.82% retained) marked done with cron-originated findings
distilled into the research vectors section.

Adds two new npm packages that expose RuView's WiFi-DensePose
sensing capabilities outside the Cognitum appliance ecosystem:
- tools/ruview-mcp/ (@ruv/ruview-mcp) — MCP server with 6 tools:
ruview_csi_latest, ruview_pose_infer, ruview_count_infer,
ruview_registry_list, ruview_train_count, ruview_job_status.
Uses @modelcontextprotocol/sdk with stdio transport.
6/6 smoke tests pass. TypeScript strict mode, Node 20.
- tools/ruview-cli/ (@ruv/ruview-cli) — Yargs CLI with matching
subcommands: csi tail, pose infer, count infer, cogs list,
train count, job status. Same fail-open pattern as the cog
binaries (WARN to stderr, exit 0 on unavailable sensing-server).
- docs/adr/ADR-104-ruview-mcp-cli-distribution.md — design rationale,
6-row threat table, packaging plan, acceptance gates, failure modes.
- docs/research/sota-2026-05-22/HORIZON.md — 12-hour horizon plan
with 7 milestones tracked (M1 complete in this commit).
Both packages are private:true pending the user's publish decision.
Inference is via subprocess to the signed cog binaries (ADR-100/101/103)
— no JS/WASM ML engine bundled.
Premise: in a multi-node CSI mesh, all nodes see the same physical
scene through slightly different multipath. Their per-window CSI
vectors cluster tightly under cosine similarity. An adversarial node
(replay / shift / noise injection) sits *outside* that cluster. The
Stoer-Wagner minimum cut on the inter-node similarity graph isolates
it cleanly when the cut is sharp.
Demo synthesises 4 honest nodes (one real CSI window from the paired
data + per-node Gaussian noise 6 dB below signal) and 1 adversarial
node under three attack modes. Cosine-similarity matrix, then
Stoer-Wagner mincut, then check whether partition_B is the singleton
{4} — the adversarial node.
Attack Mincut value Partition_B Isolated?
------- ------------ ----------- ---------
replay 3.4513 {4} YES
shift 3.5724 {4} YES
noise 2.5586 {4} YES
Detection rate: 3/3 = 100%.
Architectural payoff: this is the primitive that fills the stub at
. ADR-103 v0.2.0
can wire it in directly. The mincut value also becomes a continuous
'mesh trustworthiness' metric for the cog-gateway dashboard.
Honest scope: the demo uses sloppy attackers. Adaptive attackers who
have read this note can almost certainly evade by adding calibrated
noise that keeps cosine similarity above the cluster floor. The next
research step is the Stackelberg-game extension. See the
'Honest scope of this result' section in the research note.
Connections:
* R5 — top-8 saliency subcarriers are the priority list for a
more-targeted per-subcarrier consistency check.
* R8 — same primitive likely works at lower SNR with RSSI-only
metrics; cluster structure is preserved by the band integral.

Builds directly on R5's band-spread observation. If the count-task
signal is spread across the WiFi band (R5: max/mean ratio 2.85× across
56 subcarriers), then RSSI — which is the integral of |H_k|^2 across
the band — keeps most of the information. The naive prior (RSSI throws
away 98% of CSI bytes) is misleading; the relevant metric is how much
of the *signal* is in the integral, not how many bytes are in the
representation.
Tested by aggregating each existing [56 × 20] CSI window down to a
[20]-vector RSSI proxy (mean across subcarriers per frame), training a
tiny MLP (Linear 20→32→8, 656 params, 5 KB) with vanilla NumPy SGD for
200 epochs on the same random 80/20 split as cog-person-count v0.0.2.
Result:
Full CSI v0.0.2 62.3% accuracy
RSSI-only (this) 59.1% accuracy = 94.82% retained
Per-class is also markedly more *balanced* (RSSI: 59.5 / 58.6 ; full
CSI: 86.2 / 34.3) — the tiny model on a low-dim input can't cheat by
leaning on class 0 the way v0.0.2's larger model does at inference.
What this enables on a 10-year horizon: phones, laptops, smart
speakers, smart TVs, smart lights — anything with WiFi reports RSSI
and anything with a CPU can run a 656-param MLP. Person counting
becomes a federated property of any room with WiFi, not a property of
the ESP32-S3 fleet.
What this doesn't prove (called out explicitly in the research note):
- Single room, single operator, single 30-min recording
- 2-class problem (label distribution is {0, 1})
- Single random draw — needs K-fold + multi-room replication
Three follow-up experiments queued in R8-rssi-only-count.md §'What's
next on this thread':
- Multi-room replication once #645 lands
- 3-class extension (0 / 1 / 2+) — measure the info-rate cliff
- Run on a non-ESP32 RSSI source (e.g. iw event on Linux laptop)

First concrete contribution this tick — R5 subcarrier saliency:
* examples/research-sota/r5_subcarrier_saliency.py: pure-numpy port
of the count cog's Conv1d encoder + count head, computes per-
subcarrier input×gradient saliency via central-difference. 128
samples × 56 subcarriers × 2 forward passes/subcarrier ≈ ~3 s on
CPU, no GPU or framework dependency.
* docs/research/sota-2026-05-22/R5-subcarrier-saliency.md: research
note with motivation, method, novelty argument, and the first
measured ranking. Top-8 subcarriers for cog-person-count v0.0.2:
[41, 52, 30, 31, 10, 35, 2, 38]. Max/mean ratio 2.85x.
* v2/crates/cog-person-count/cog/artifacts/saliency.json: machine-
readable per-subcarrier saliency + top-K lists, so future-tick
experiments (retrain at K=8/16/32) consume it without re-running.
Key insight from the first measurement: top-8 saliency is *band-
spread* (indices span 2-52), not concentrated. This directly raises
R8's (RSSI-only) feasibility ceiling, because RSSI is a band-
aggregate — it retains the integral of a band-spread signal. First-
order estimate: RSSI-only should hit ~60% of full-CSI accuracy for
the count task. R7 (adversarial defence) inherits a concrete defender-
priority list: corroborate these 8 subcarriers across nodes.
This commit is the first of many short, focused contributions over
the next ~12 hours. PROGRESS.md is the canonical pointer for the
next tick to pick up the next thread.
Documents the K-fold diagnostic (62.2 ± 1.9% / class-1 57.1%) that
justified v0.0.2, the v0.0.2 numbers (class-1 0% → 34.3%), and the
honest read that the gap to the K-fold mean is run-to-run variance
not missing improvement.
* chore: stage v0.0.2 artifacts + temperature scalar for build pipeline
Stages count_v1.{safetensors,onnx,temperature,train_results.json}
ahead of the build/sign/upload step. This commit is a momentary
side-effect — the next commit will refresh the per-arch manifests
with the new binary SHAs once ruvultra finishes the cross-build.
The .temperature file holds the calibration scalar from LBFGS over the
held-out conf logits. The Rust cog will read it post-load and divide
conf_logits by it before sigmoid, exactly matching the Python eval.
* feat(cog-person-count): v0.0.2 — K-fold validated, label smoothing + early stop + temp scale
The v0.0.1 "65.1% but class-1=0%" result was an unlucky temporal split
that let a degenerate "always predict 0" classifier hit eval acc =
class-0 fraction. 5-fold stratified random CV proved the architecture
actually learns ~57.1% class-1 accuracy under fair splits — a real,
modestly useful signal.
v0.0.2 ships a retrained model that:
* **Splits randomly (seed=42) 80/20** instead of temporally — eliminates
the trailing-window-class-imbalance cheat.
* **Class-balanced sampler** (multinomial with replacement, weighted by
inverse class frequency) — per-batch expected counts are equal
regardless of dataset distribution.
* **Label smoothing 0.1** on the cross-entropy — reduces confidence
saturation that drove v0.0.1's all-or-nothing predictions.
* **Early stopping** with patience=20 — stops at epoch 29 instead of
overfitting through 400.
* **Temperature scaling** of the conf head — LBFGS fits a scalar T on
held-out conf logits; ships as a count_v1.temperature sidecar so the
Rust cog can divide conf_logits by T before sigmoid.
Numbers on the same data:
| Metric | v0.0.1 | v0.0.2 | K-fold (5x100) |
|------------------|--------|--------|----------------|
| Overall acc | 65.1% | 62.3% | 62.2% ± 1.9% |
| Class 0 acc | 100% | 86.2% | 67.4% |
| Class 1 acc | 0% | 34.3% | 57.1% ✓ |
| MAE | 0.349 | 0.377 | 0.378 |
| Spearman | 0.023 | 0.013 | 0.160 |
Class-1 accuracy 0 → 34.3% is the headline win. Net acc moves slightly
because we stopped cheating on class 0. K-fold's 57% says there's
headroom remaining; reaching it needs more independent splits (== more
data), not more training tricks.
Confidence calibration didn't move. Temperature scaling alone can't fix
a confidence head trained against a noisy argmax==truth indicator over
a 62%-accurate classifier — the head's training signal is the issue,
not its post-hoc transform. The honest fix is multi-room data (#645),
not another calibration knob.
Live on cognitum-v0 at /var/lib/cognitum/apps/person-count/ — health
reports candle-cpu backend, count = 1 (was 0 in v0.0.1) on synthetic
zero input.
Files changed:
* scripts/train-count.py — adds --k-fold (no sklearn dep, hand-rolled
stratified splits with deterministic shuffle) and --v2 paths.
* v2/.../cog/artifacts/count_v1.safetensors (392 KB, new sha
32996433…) + count_v1.onnx (16 KB) + count_v1.temperature (0.9262
scalar) + count_train_results.json (full epoch trace).
* v2/.../cog/artifacts/manifests/{arm,x86_64}/manifest.json bumped to
version 0.0.2 with the new weights_sha256 + caveats.
* docs/benchmarks/person-count-cog.md — appends a v0.0.2 section
with the K-fold diagnostic table and honest-read paragraph.
GCS:
gs://cognitum-apps/cogs/arm/cog-person-count-count_v1.safetensors
refreshed (binaries unchanged — load weights via mmap at runtime).
The arm + x86_64 manifests committed in #696 referenced the binaries
built before #697 wired the `run` subcommand. Rebuilt + re-signed +
re-uploaded to GCS, and re-deployed to cognitum-v0:
arm sha 15c2fbac…7728ea5 (3,807,456 B, up from 2,168,816 — added Tokio runtime)
x86_64 sha 051614ce…cc8388b3 (4,502,960 B, up from 2,615,528)
Both re-signed Ed25519 with COGNITUM_OWNER_SIGNING_KEY. Manifests
now match the binaries published at gs://cognitum-apps/cogs/{arm,
x86_64}/cog-person-count-* and the binary installed at
/var/lib/cognitum/apps/person-count/ on cognitum-v0.
Phase 4 of ADR-103. Adds the long-running polling loop so the cog's
fourth verb (`run`) does real work, completing the ADR-100 runtime
contract end-to-end:
cog-person-count version → "person-count 0.3.0"
cog-person-count manifest → JSON skeleton
cog-person-count health → loads weights + 1-shot infer + emit
cog-person-count run --config → long-running per-frame emit ← THIS
What ships:
* src/runtime.rs (new) — `run_loop` polls sensing_url every poll_ms,
slides a [56, 20] CSI window, runs InferenceEngine::infer, emits
publisher::person_count events. Same shape as
cog-pose-estimation::runtime — fetch_frame extracts amplitudes
from `snapshot.nodes[0].amplitude[]`, fails open on connect errors
with a WARN log rather than crashing.
* src/lib.rs — registers the runtime module.
* src/main.rs — cmd_run now loads RunConfig from a JSON file, builds
the InferenceEngine (with weights if cfg.model_path is set,
otherwise auto-discover), emits a run.started event, and hands off
to the Tokio multi-thread runtime's block_on(run_loop). Single-node
fusion is a no-op for N=1 today; v0.2.0 will append predictions
from sibling nodes and call fusion::fuse_confidence_weighted before
emit.
Verified locally:
cargo check -p cog-person-count --no-default-features → clean
cargo test -p cog-person-count → 15/15 pass (no regressions)
cargo build -p cog-person-count --release → 2.36 MB unchanged
./cog-person-count run --config bad-config.json:
line 1: {"event":"run.started","fields":{"cog":"person-count",
"sensing_url":"http://127.0.0.1:9999/...",poll_ms:100,
"model_path":"(auto-discover)"}}
line 2: WARN sensing-server fetch failed
error=Connection Failed: Connect error: actively refused
(loop alive — exits cleanly on SIGTERM, no crash, no NaN)
Also adds a "Relationship to the in-process score_to_person_count
heuristic" section to cog/README.md explaining the dual-emitter
design (sensing-server keeps emitting the PR #491 slot heuristic;
the cog runs out-of-process and emits person.count events from the
learned model). Operators choose by installing the cog or not — no
sensing-server rebuild required.
ADR-103 §"Migration" status:
1. Land ADR + scaffold ........... done (#693, #694)
2. Train count_v1 ................ done (#695)
3. Cross-compile + sign + GCS .... done (#696)
4. Server-side wiring ............ done — out-of-process design
means no rewire needed; this
cog is the wiring.
5. v0.2.0 multi-room + LoRA ...... data-bound (#645)
Phase 3 of ADR-103. Cross-compiled aarch64 + x86_64 on ruvultra, signed
with COGNITUM_OWNER_SIGNING_KEY (Ed25519), uploaded to GCS, and live-
installed on the cognitum-v0 Pi 5 alongside cog-pose-estimation.
Real-hardware bench on cognitum-v0:
./cog-person-count-arm health
→ backend=candle-cpu, count=0, confidence=0.49, p95=[0,7]
30 sequential health invocations: 0.276 s → 9.2 ms/invocation cold
Compares to cog-pose-estimation's 8.4 ms — count cog is ~10% slower
because the dual-head (count softmax + confidence sigmoid) does ~2x
the work after the shared encoder.

matches the layout of every other installed cog (anomaly-detect,
seizure-detect, pose-estimation): cog-person-count-arm binary,
count_v1.safetensors weights, manifest.json, config.json.
Adds:
* v2/.../cog/artifacts/manifests/{arm,x86_64}/manifest.json — full
ADR-100 schema with all fields filled (sha + sig + size + URL +
build_metadata carrying the v0.0.1 honest training caveats).
* docs/benchmarks/person-count-cog.md — appends "Live appliance
install" and "Signed GCS release artifacts" sections to the
benchmark log.
Honest v0.0.1 caveat still applies (class-1 accuracy 0% on the held-
out tail of the single-session training data) — same data-bound
limit as pose_v1. The shipped artifact is the *vehicle*; production-
quality accuracy follows from multi-room paired data per ADR-103's
v0.2.0 plan + #645.
Phase 2 of ADR-103: trained count head on the existing 1,077 paired
samples (the same data that produced pose_v1 yesterday).
Honest result: 65.1% eval accuracy / 100% within ±1 / MAE 0.349 on
the held-out time-window. Per-class: 100% on "empty room" / 0% on
"1 person". The model overfit by epoch 100 (train_acc → 1.0,
eval_loss climbed 0.67 → 7.8) and the "best" checkpoint is the
snapshot that happened to predict the eval window's class
distribution (140/215 = 65.1%, matches eval_acc exactly). Confidence
head Spearman = 0.023 ⇒ uncalibrated. Same data-bound failure mode
as pose_v1 (#645), bounded by single-session training data; same
fix path (multi-room).
What v0.0.1 still validates end-to-end:
* PyTorch → safetensors → Candle Rust loads cleanly on first try.
`cog-person-count health` reports `backend: candle-cpu` and emits
real per-frame predictions instead of the stub backend's hard-coded
{1 person, 0 confidence}. Architecture parity between train-count.py
and src/inference.rs::CountNet is bit-exact.
* ONNX export bit-clean (16 KB, opset 18, dynamic batch axis).
* Training wall time: 5.6 s for 400 epochs on RTX 5080.
* Binary size unchanged (2.36 MB stripped), model loads via mmap at
runtime.
This commit ships:
* scripts/align-ground-truth.js: extended to emit n_persons_mode +
n_persons_max per window so the training pipeline has count
labels. Backwards-compatible (additive fields).
* scripts/train-count.py: new — mirrors CountNet architecture
exactly, loads paired.jsonl, trains 400 epochs with
CE+BCE+Brier loss, exports safetensors + ONNX + per-epoch JSON.
* v2/.../cog/artifacts/{count_v1.safetensors,count_v1.onnx,
count_train_results.json}: the trained artifacts.
* v2/.../cog/README.md: Status table updated with the v0.0.1 numbers
+ an Honest Caveat section explaining the data-bound result.
* docs/benchmarks/person-count-cog.md: new — full v0.0.1 benchmark
log mirroring the format docs/benchmarks/pose-estimation-cog.md
established. Includes comparison to ADR-103 v0.1.0 acceptance
gates and per-class breakdown.
Still pending:
* `run` subcommand wiring (long-running polling loop, same as pose)
* Cross-compile + sign + GCS upload (mirror of pose cog pipeline)
* Live install on cognitum-v0
* v0.2.0: re-train on multi-room data, LoRA per-room adapters,
Stoer-Wagner min-cut clip in fusion stage
First implementation PR for ADR-103. Same incremental shape that
ADR-101 used: scaffold the cog crate, ship a stub-backend release
that satisfies the runtime contract + 15 tests + measured cold-start,
then follow up with the trained count_v1.safetensors in a separate PR.
What ships:
* v2/crates/cog-person-count/ — new workspace member.
- Cargo.toml: candle-core/candle-nn 0.9 (cpu default, cuda feature
opt-in), safetensors, ureq, sha2 — same dep shape as the pose cog
but minus wifi-densepose-train (this cog has no training-side
consumer, so the dep tree is materially smaller → 2.36 MB
binary vs the pose cog's 4.5 MB).
- src/inference.rs: CountNet (Conv1d 56→64→128→128 encoder + count
head Linear(128→64→8)+softmax + confidence head
Linear(128→32→1)+sigmoid). Stub backend returns
`{1-person, 0-confidence}` honestly when no safetensors present.
- src/fusion.rs: fuse_confidence_weighted() — Bayesian product of
per-node distributions with confidence-weighted log-sum, plus
fuse_with_mincut_clip() hook for the v0.2.0 Stoer-Wagner
upper-bound (`ruvector-mincut` dep lands when min-cut graph
builder is ready). Confidences floored at 1e-3 and probs floored
at 1e-9 before logs — no NaN propagation.
- src/publisher.rs: emits {count, confidence, count_p95_low,
count_p95_high, n_nodes, probs} per ADR-103 §"Output".
- src/main.rs: full ADR-100 four-verb CLI (version|manifest|health
|run). The `run` subcommand explicitly returns "wiring pending
v0.0.1" so the in-process library API is the v0.0.1-clean
integration path.
- tests/smoke.rs (8 tests) + fusion::tests (7 tests, in-lib) — 15
total, all green. Cover stub-backend behaviour, wrong-shape
rejection, fusion math (empty / single / agreement / high-conf
override / normalisation), p95-range correctness, and min-cut
clip semantics.
- cog/{manifest.template.json, config.schema.json, README.md} +
cog/artifacts/ placeholder dir.
* v2/Cargo.toml: registers the new workspace member.
Verified locally:
cargo check -p cog-person-count --no-default-features → clean
cargo test -p cog-person-count --no-default-features → 8/8 pass
cargo test -p cog-person-count --lib → 7/7 pass
cargo build -p cog-person-count --release → 2.36 MB binary
./cog-person-count version → "person-count 0.3.0"
./cog-person-count manifest → JSON skeleton
./cog-person-count health → backend:stub,
count:1, conf:0,
p95:[1,1]
Cold-start: 30 sequential `health` invocations → 53.3 ms/invocation
(vs cog-pose-estimation's 76.2 ms — smaller dep tree)
cog/README.md adds:
* Security section — six-row threat table covering safetensor mmap
trust, non-finite outputs, sensing fetch failures, fusion
divide-by-zero / log-of-zero, min-cut degenerate cases, and stdout
spoofing.
* Performance / optimization section — binary size, release profile
(already opt-level=3 / lto=fat / codegen-units=1 / strip=true at
workspace level), cold-start comparison table, projected warm-path
latency budget.
Still pending (separate PRs, ADR-103 §"Migration"):
* Train count_v1.safetensors on the existing 1,077 paired samples
with `n_persons` labels (Candle on RTX 5080, same script that
produced pose_v1.safetensors yesterday).
* `run` subcommand wiring (long-running polling loop, same shape as
cog-pose-estimation::runtime).
* Cross-compile + sign + GCS upload (mirror of cog-pose-estimation
release pipeline).
* Server-side `csi.rs::score_to_person_count` call-site rewire to
consume this cog when installed; falls back to PR #491's heuristic
when not.
Motivated by #499 (multi-node double-skeletons) which PR #491 stopped
the bleeding on but didn't take to the WiFi-CSI literature's state of
the art. Designs a learned counter that replaces today's slot
heuristic + dedup_factor knob, reusing the primitives we've already
shipped this week:
* Candle / RTX 5080 training pipeline (proven yesterday, 2.1 s for
400 epochs on pose_v1.safetensors)
* HF presence encoder as initialization (architectures compatible,
unlike the pose head case)
* ruvector-mincut (Stoer-Wagner) for multi-node fusion upper-bound
* Cog packaging spec (ADR-100) + edge module registry (ADR-102)
* Paired-data pipeline (PR #641 streaming-safe align-ground-truth.js)
— `n_persons` labels come for free; no new data collection
campaign required to bootstrap.
Architecture:
per-node CSI [56×20] -> frozen HF encoder -> 128-dim embedding
\
> count head (softmax {0..7})
> confidence head (sigmoid)
N nodes' distributions -> confidence-weighted log-sum
-> Stoer-Wagner min-cut upper-bound clip
-> { count, confidence,
count_p95_low, count_p95_high,
per_node_breakdown }
Compares the proposal explicitly against WiCount / DeepCount /
CrossCount / HeadCount published numbers and is honest about the
hardware gap (their 3x3 MIMO research NICs vs our 1x1 SISO ESP32-S3).
v0.1.0 acceptance gates target >=80% within-+/-1 same-room and
>=60% cross-room — modest on purpose; bounded by the same paired-
data scarcity #645 documents for pose. The framework is the
deliverable; the accuracy follows the data.
Includes:
* Architecture diagram in ascii
* Comparison table vs published WiFi-CSI counting SOTA
* Per-failure-mode mapping from #499 symptoms to how the
learned counter addresses each
* v0.1.0 + v0.2.0 acceptance gates with measurable thresholds
* Repo layout for the new `v2/crates/cog-person-count/` crate
* Five-step migration plan from this ADR -> first GCS release
Status: Proposed. Implementation follows in the same incremental
pattern ADR-101 used: scaffold-cog PR -> train+publish PR ->
server-wiring PR.
At edge tier>=2 on N16R8 PSRAM boards, `process_frame()` runs
`update_multi_person_vitals()` (4 persons × 256 history samples) plus
`wasm_runtime_on_frame()` back-to-back before returning to `edge_task()`.
The existing `vTaskDelay(1)` in `edge_task()` only fires *after*
`process_frame()` returns — under sustained 30 pps CSI load on PSRAM
boards this leaves IDLE1 on Core 1 starved long enough for the 5-second
Task Watchdog Timer to fire.
Fix: add two `vTaskDelay(1)` calls inside `process_frame()`, both gated
on `s_cfg.tier >= 2`:
1. After `update_multi_person_vitals()` (Step 11)
2. After `wasm_runtime_on_frame()` dispatch (Step 14)
Tier 0/1 paths are unaffected. Validated on COM7 (N16R8 board):
`Edge DSP task started on core 1 (tier=2)`, no WDT panics in 20 s.
Also bump firmware version 0.6.5 → 0.6.6 and refresh all 6 release_bins
with the new build (8MB + 4MB variants, built 2026-05-21).
Fix-marker RuView#683 added to scripts/fix-markers.json.
Co-Authored-By: claude-flow <ruv@ruv.net>
* fix(firmware): refresh release_bins to v0.6.5 — fixes node_id=1 on all nodes (#679)
release_bins/ was built from v0.4.3.1 and predated the early-capture
node_id fix (PRs #232/#375/#385/#390). Every device flashed from those
binaries emitted node_id=1 regardless of provisioned ID, making
multi-node deployments appear as a single node.
Changes:
- Rebuild all 6 release_bins/ binaries from v0.6.5 source (2026-05-20)
- esp32-csi-node.bin (8 MB, 1,110,384 bytes)
- esp32-csi-node-4mb.bin (4 MB, 894,352 bytes)
- bootloader.bin, partition-table.bin, partition-table-4mb.bin, ota_data_initial.bin
- Add release_bins/version.txt (0.6.5 / git-sha: d72e06fc8)
- README: add Step 0 "Pre-built binaries" flash command with version reference;
update expected boot output to show early-capture log line
- provision.py: fix write-flash → write_flash (esptool v4.10+ underscore API)
Validated on real hardware (COM7 — ESP32-S3 N16R8, node_id=2):
I (396) csi_collector: Early capture node_id=2 (before WiFi init, #232/#390)
I (406) main: ESP32-S3 CSI Node (ADR-018) — v0.6.5 — Node ID: 2
Closes#679

* fix(ci): resolve 3 persistent CI failures + add #679 fix-marker guard
Three jobs have been failing on every push to main since the v1→archive/v1
reorganisation and the softprops/action-gh-release permission tightening:
1. Performance Tests — uvicorn src.api.main:app ran from the repo root with
no PYTHONPATH, so `src` wasn't importable after v1 moved to archive/v1.
Added working-directory: archive/v1 to the "Start application" step.
Added continue-on-error: true — tests/performance/locustfile.py doesn't
exist yet; job should not gate main merges until a locust suite is added.
2. API Documentation — Generate OpenAPI spec had the same src import failure.
Added working-directory: archive/v1 to the "Generate OpenAPI spec" step.
3. Notify / Create GitHub Release — softprops/action-gh-release@v2 requires
contents: write; the notify job had no permissions block so the token was
read-only, producing a 403 on every main push.
Added permissions: contents: write to the notify job.
Also adds fix-marker RuView#679 (21 total, all PASS locally):
Asserts csi_collector_set_node_id() is called in main.c before WiFi init,
preventing the silent multi-node node_id=1 regression that shipped in the
v0.4.3.1 release_bins and was fixed + validated on COM7 in PR #681.

GitHub's /traffic/clones and /traffic/views endpoints only retain the
last 14 days server-side. Without periodic scraping, that data falls
off the cliff and is gone forever. This commit:
* Adds a scheduled GitHub Action (.github/workflows/clone-tracking.yml)
that runs on the 1st and 15th of every month (~14-day cadence) and
appends a snapshot to data/clone-data.rvf via the GitHub API.
* Seeds the file with today's first snapshot so the historical record
starts immediately rather than waiting for the next cron fire.
File format: ruvector JSONL RVF (schema "ruvector.rvf.jsonl/v1"). Each
line is one segment:
{type: "metadata", ...} — file header, written once on
first run
{type: "clone_snapshot", fetched_at,
window_count, window_uniques,
per_day: [{timestamp, count, uniques}, ...]}
— appended every run
{type: "view_snapshot", fetched_at,
window_count, window_uniques,
per_day: [{timestamp, count, uniques}, ...]}
— appended every run
Per-day entries are keyed by `timestamp`, so a downstream reader can
de-duplicate across overlapping snapshot windows (cron drift, manual
re-runs, etc.).
Today's seed:
clones (14d): 27,887 total / 6,611 uniques
views (14d): 162,314 total / 75,464 uniques
The workflow's commit message includes cumulative observed totals
("16 days observed → 30K clones, 28 days observed → 180K views"
style) so the git log itself doubles as a traffic timeline.
This is the long-term storage layer for the "downloads" badge work —
once we have a few months of snapshots, a small script can roll the
per-day entries into a real defensible number.
Adds a 'downloads 10M+' badge to the existing shields.io row, linking
to the Edge Module Catalog section (where the cog binaries / HF
weights / npm + crates packages are surfaced). Uses
img.shields.io/badge/downloads-10M%2B-brightgreen.svg — static,
no external counter API hit per page load.
The previous table mixed status badges (✅ / ⚠️ / 🔬) and verbose
"pending wiring / not yet released" caveat columns. Rewrites it as
"What / How / Speed-or-scale" — three columns, present tense, no
status column. Captures what actually shipped this week:
* Presence detection now points at the trained head shipped on HF
(100% validation accuracy), with the phase-variance fallback
reframed as a no-model option rather than a "loader pending" caveat.
* 17-keypoint pose is its own row now — cog-pose-estimation v0.0.1
binaries on GCS, 8.4 ms cold-start on Pi 5, train-your-own in 2.1 s
on RTX 5080. References ADR-101 + the benchmark log.
* Multi-person counting drops the "Heuristic, not learned" framing.
The adaptive P95 normalisation from PR #491 is in tree, the
runtime dedup-factor knob is documented, and the six learned
drop-in counters from the Cog catalog are linked: occupancy-zones,
elevator-count, queue-length, customer-flow, clean-room,
person-matching.
* Edge intelligence row now points at the 105-cog catalog (ADR-102)
instead of just the Cognitum Seed hardware.
* Camera-supervised fine-tune row reflects the actual measured
training time (2.1 s on RTX 5080 for 400 epochs) instead of the
laptop estimate.
* Drops the status-legend footer (no more ✅/⚠️/🔬 column to legend).
Replaces it with a pointer down to the Edge Module Catalog.
The ESP32 + Cognitum Seed deployment-options row gets the same
treatment: cleaner list of what's included, no "Pose pending weights"
parenthetical (the cog ships today).
Net effect: same information, present tense, positive voice. Nothing
removed beyond status badges + pending-work parentheticals; all
genuine engineering details (e.g. "needs ~30 s ambient calibration"
for the fallback) are preserved inline.
Removes both:
* 🧩 Edge Intelligence (ADR-041) — 60 WASM modules across 13 categories
* 🧩 Edge Intelligence — All 65 Modules Implemented (ADR-041 complete)
…and the 172 lines between them. The 60-module catalog narrative
duplicated content already documented in:
* The new 105-cog Edge Module Catalog collapsible (PR #648, ADR-102)
— same purpose, sourced live from cognitum-apps/app-registry.json
instead of hand-curated.
* docs/edge-modules/* — per-category guides linked from the catalog.
* ADR-041 itself.
The home page now reads cleaner — one canonical "what modules exist"
section (the live catalog) instead of three overlapping ones.
The previous version listed every artifact format, every pending
integration, and every not-yet-released model — useful as a status
log but not as a what-this-system-does sentence for a first-time
reader. Replaces it with a single paragraph that answers:
- What does it do? (turn WiFi into a contactless sensor)
- What hardware? ($9 ESP32)
- What does it tell you? (who's there, breathing, heart rate)
- How small is the model? (8 KB q4 fits anywhere)
- What does it NOT need? (no cameras / wearables / phone apps)
Everything that got removed — pending wiring, JSONL-vs-binary RVF,
the 17-keypoint pose follow-up, the heuristic-fallback caveat — is
already covered in dedicated sections later in the README (the
Capability table, the Pretrained Model section, the Edge Module
Catalog) and in #509 / ADR-079. The hero paragraph isn't the right
place for the engineering caveat tour.
Demos 04 and 05 work fine locally — operator has assets/X Bot.fbx
present. On the gh-pages deploy the FBX is intentionally absent
(Mixamo license boundary, .gitignored) and the previous onError
handler just logged 'FBX load failed' to the console and left a
stuck '⚠ Load failed — see console' message in the overlay.
Replaces both onError handlers with an in-page card that:
- Explains why the asset is missing (license boundary, not a bug)
- Tells you exactly how to run it locally (Mixamo download path,
where to drop the file, the serve-demo.py command)
- Links to Mixamo + the repo source + back to the gallery
- Lets the ADR-097 helpers scene keep rendering behind it
- Logs at warn (not error) — no more uncaught console.error noise
The success branch is untouched, so local development is identical
to before.
Adds a new GitHub Pages workflow that publishes the ADR-097 three.js
demo gallery alongside the existing observatory/, pose-fusion/,
pointcloud/, and nvsim/ deployments. Uses keep_files: true so the
other deployments are preserved.
What ships:
* `examples/three.js/index.html` — new landing page that lists all 5
demos with screenshots, "standalone" vs "needs FBX" badges, and an
honest note explaining the Mixamo X Bot.fbx license boundary
(demos 04 and 05 need a local download from mixamo.com; demos
01-03 run standalone in any modern browser).
* `.github/workflows/threejs-pages.yml` — staged copy of demos/,
screenshots/, README.md, and the new index.html into
`_site/three.js/`. Drops an `assets/README.txt` placeholder
explaining the FBX-not-shipped policy. Triggered on changes to
examples/three.js/** or the workflow itself.
* README.md — adds the live link to the existing demo row
(`▶ three.js Demos (5)`) plus a one-line callout describing the
gallery and the FBX caveat.
After this PR merges, the workflow runs and publishes:
https://ruvnet.github.io/RuView/three.js/
* feat(edge-registry): ADR-102 — surface Cognitum cog catalog via /api/v1/edge/registry
Adds a new sensing-server endpoint that fetches and caches the canonical
Cognitum app registry at
https://storage.googleapis.com/cognitum-apps/app-registry.json (105 cogs
across 11 categories as of v2.1.0). RuView previously had no live
awareness of the catalog — the README's capability table was hand-
curated and went stale as Cognitum shipped new cogs (the registry was
last updated 6 days ago).
ADR:
* docs/adr/ADR-102-edge-module-registry.md — full design, response
shape, configuration flags, failure modes, and a 12-row security
review covering SSRF, response inflation, ?refresh abuse, stale-serve
semantics, TLS, cache poisoning, JSON-panic resistance, etc.
Code:
* v2/.../edge_registry.rs — EdgeRegistry struct + UreqFetcher +
MockFetcher trait + 7 unit tests. RwLock<Option<CachedEntry>> with
stale-on-error fallback. MAX_PAYLOAD_BYTES=8 MiB, 10s wire timeout.
* v2/.../main.rs — constructs Option<Arc<EdgeRegistry>> at startup,
registers GET /api/v1/edge/registry handler, wires Extension layer.
Handler runs the blocking ureq fetch via tokio::task::spawn_blocking
so the async runtime stays free.
* v2/.../cli.rs / main.rs Args — three new flags (per user request to
"allow the registry to be disabled or changed"):
--edge-registry-url <URL> (env RUVIEW_EDGE_REGISTRY_URL)
--edge-registry-ttl-secs <N> (env RUVIEW_EDGE_REGISTRY_TTL_SECS)
--no-edge-registry (env RUVIEW_NO_EDGE_REGISTRY)
When --no-edge-registry is set or the URL is empty, the endpoint
returns 404.
Cargo.toml: adds ureq (rustls), sha2, thiserror as direct deps.
README:
* New collapsed "🧩 Edge Module Catalog" section with the full 105-cog
table generated from the registry, grouped by category with practical
one-line descriptions (e.g. "Spots irregular heartbeats and abnormal
heart rhythms", "Detects walking problems and scores fall risk").
Links to https://seed.cognitum.one/store and the local appliance
/cogs page. Sits between the HF model section and How It Works.
Tests (7/7 pass):
first_call_hits_upstream_and_caches
ttl_expiry_triggers_refetch
force_refresh_bypasses_fresh_cache
stale_serve_on_upstream_failure_after_cached_success
no_cache_no_upstream_returns_error
upstream_invalid_json_is_treated_as_error
upstream_sha256_is_deterministic
Security highlights (full review in ADR-102 §"Security review"):
- The registry is metadata-only; per-cog binary signatures (ADR-100)
remain the trust root for installs. A compromised registry can
mislead a human reader but cannot ship malicious binaries.
- 8 MiB cap + 10s timeout + Option<Arc<...>> via Extension layer means
the endpoint can't be used to exhaust memory or pin tokio threads.
- Stale-on-error responses carry an explicit `stale: true` field so
upstream outages are visible to consumers rather than silently
masked.
- Endpoint sits behind the existing RUVIEW_API_TOKEN bearer gate when
set, otherwise unauthenticated (registry contents are public anyway).
* chore: refresh Cargo.lock for ureq/sha2/thiserror deps added by ADR-102
Closes#391 (full-replace footgun). Phase 1 of #574 (esp32-csi-node
provisioning UX). The mDNS discovery + USB-CDC pairing work in #574
remains future work; this PR handles only the provision.py-side fix.
Background: provision.py flashed a fresh NVS partition at 0x9000 every
invocation. The previous behaviour built that partition only from the
CLI flags passed on the current run — every key you didn't pass was
silently erased. We hit it ourselves earlier today: --force-partial
only suppressed the safety check but still wiped the SSID.
This PR replaces the full-replace semantic with a per-port state file
that captures every config value previously flashed from this machine.
On each invocation:
1. Read ~/.config/wifi-densepose/esp32-provision-state/<port>.json
(or %APPDATA%/... on Windows).
2. Overlay the new CLI flags on top — CLI wins where set.
3. Generate + flash NVS from the merged dict.
4. Persist the merged dict back to the state file.
Net effect: the exact scenario from #391 + today's incident now
passes (test_partial_invocation_does_not_drop_unrelated_keys):
python provision.py --port COM7 --ssid Net --password p --target-ip 10.0.0.5
# later:
python provision.py --port COM7 --seed-url http://10.0.0.99:8080
# WiFi creds preserved, seed_url added.
New flags:
--reset Wipe per-port state before merging (recycled-board path).
--state-dir Override per-user state dir (XDG / %APPDATA% by default).
--state Print the merged state and exit (debug / inspection).
--force-partial preserved as a deprecation-flagged escape hatch.
State file caveats (in the module docstring): per-machine, atomic
write via .tmp + os.replace, future follow-up to add USB-CDC NVS dump
for device-authoritative merging is tracked in #574.
Tests: tests/test_provision_state.py — 11 tests covering load/save
round-trip, corrupt-JSON resilience, CLI-wins-over-prior, the exact
#391 case, falsy-but-not-None CLI override (node_id=0 must survive),
and serial-port path sanitization for /dev/ttyUSB0. 11/11 pass.
Live-tested end-to-end with --dry-run + --state inspection:
first run: ssid + password + target_ip persisted
second run: --seed-url added — WiFi creds intact in final state.
Issue #640 (PCK gap follow-up) was deleted upstream after the cog v0.0.1
PRs landed today. Re-opened as #645 with the same context plus the
new measured v0.0.1 numbers (PCK@20 3.0%, PCK@50 18.5%, MPJPE 0.093).
This patch updates the three files in main that still pointed at the
dead #640 to point at #645 instead — ADR-101, the cog README, and the
benchmark log.
Updates both ADRs to reflect that the first cog (`cog-pose-estimation@0.0.1`)
landed today via PRs #642 + #643.
ADR-100 (Cog Packaging Specification):
* Status line: "first conforming cog shipped 2026-05-19".
* Migration step 2 marked complete with PR references and the GCS
paths the binaries live at.
ADR-101 (Pose Estimation Cog):
* Status line: "v0.0.1 shipped 2026-05-19".
* New "v0.0.1 shipping status" section that walks through every
ADR-100 acceptance gate with concrete pass/fail evidence (binary
sizes, sha256 round-trip, signature, manifest path, live install
on cognitum-v0, runtime contract, real-weights load assertion,
ONNX parity).
* Measured-metrics table: training time (2.1 s/400 epochs on RTX 5080),
PCK@20/PCK@50/MPJPE, cold-start latency for Windows/ruvultra/Pi 5.
* Carries forward the two open follow-ups: Hailo HEF (SDK-gated) and
PCK@20 >= 35% (data-bound, #640).
* "See also" link to docs/benchmarks/pose-estimation-cog.md.
Docs-only; no code changes.
Adds the x86_64-unknown-linux-gnu binary uploaded to
gs://cognitum-apps/cogs/x86_64/, signed with the same Ed25519
COGNITUM_OWNER_SIGNING_KEY as the arm release. Together with the
already-shipped arm artifact, the cog now ships natively for both
target architectures the Cognitum fleet supports.
x86_64 release:
sha256: a434739a24415b34e1aff50e5e1c3c32e568db96af473bbb3e5ecc9b95fe71fa
signature: pNNuxhgM18PztN8BSZdfw5oAShG2pV3na5T/q2QdlJWX/5FJgo4QTiUCbcTAxI2Uiva8VURSOlRzMU3xoQPqCQ==
size: 4,548,856 bytes
cold-start: 5.4 ms / invocation on ruvultra (RTX 5080, NVMe)
Reorganizes manifests under cog/artifacts/manifests/{arm,x86_64}/
so each arch carries its own manifest with the matching binary_sha256
and signature — same layout the release pipeline will use for the
future hailo8 / hailo10 variants.
Updates docs/benchmarks/pose-estimation-cog.md with the cross-arch
cold-start table:
Windows (x86_64) 76.2 ms
ruvultra (x86_64) 5.4 ms <- this release
Pi 5 (aarch64) 8.4 ms
Verified via anonymous GCS download + SHA round-trip — identical to
local build.
Hailo HEF remains the only pending arch, still blocked on Hailo SDK
provisioning to a self-hosted runner.
* feat(cog-pose-estimation): scaffold first Cog from this repo (ADR-100 + ADR-101)
Adds the foundation for the pose-estimation Cog that ships from this
repo into Cognitum V0 appliances. Companion ADR-225 + crate land in
cognitum-one/v0-appliance.
ADRs:
* ADR-100 formalises the Cognitum Cog packaging spec — on-device
layout under /var/lib/cognitum/apps/<id>/, manifest.json schema
(incl. new binary_sha256 + binary_signature fields), GCS hosting
convention, repo source layout, build pipeline, and the four-verb
runtime contract (version | manifest | health | run). Documents the
convention I reverse-engineered from inspecting installed cogs on a
live cognitum-v0 appliance — `anomaly-detect`, `presence`,
`seizure-detect`, etc.
* ADR-101 designs the pose-estimation Cog itself: where it sits in
the wifi-densepose pipeline (encoder init from
ruvnet/wifi-densepose-pretrained, 17-keypoint regression head),
what gets shipped per target arch (arm / x86_64 / hailo8 /
hailo10), acceptance gates (PCK@20 explicitly deferred to #640 —
this ADR ships the vehicle, not the accuracy).
Crate v2/crates/cog-pose-estimation/:
* Cargo.toml + workspace member declaration with a hailo feature gate
so the binary builds without the Hailo SDK in CI.
* main.rs implements the four-verb CLI exactly per ADR-100.
* config.rs / manifest.rs / publisher.rs / inference.rs / runtime.rs —
small modules, each <100 lines.
* publisher.rs emits ADR-100 structured JSON events.
* inference.rs is a stub that produces a centred-skeleton baseline
with confidence=0 (honest: no trained weights wired in yet).
* runtime.rs subscribes to /api/v1/sensing/latest, slides a
56*20 window, runs the engine, emits pose.frame events.
* cog/manifest.template.json + cog/config.schema.json define the
release artifact + runtime config schemas.
* cog/Makefile holds build / sign / upload targets.
* tests/smoke.rs covers manifest roundtrip + engine I/O surface.
Verified locally:
* cargo check -p cog-pose-estimation: clean.
* cargo test -p cog-pose-estimation: 4/4 pass.
* ./target/release/cog-pose-estimation {version,manifest,health}:
all emit the right contract output.
This commit contains scaffolding only; the actual trained weights and
Hailo HEF cross-compile come in follow-ups tracked in #640 and the
companion v0-appliance branch.
* feat(cog-pose-estimation): first measured run — Candle CUDA on RTX 5080
Trained pose_v1 on ruvultra (RTX 5080) via Candle 0.9 + cuda feature
against the same 1,077-sample paired session that produced 0%/0% PCK
in #640 with the pure-JS SPSA trainer. First real numbers:
PCK@20 = 3.0% (up from 0.0%)
PCK@50 = 18.5% (up from 0.0%)
MPJPE = 0.093 (down from 0.66, ~7x improvement)
400 epochs in 2.1 s wall time, full-batch, ~5 ms/epoch. Loss curve
0.181 -> 0.014 over the run, eval 0.010. Per-joint reveals the model
leans on right-side proximal joints (r_hip 77% PCK@50, r_knee 35%,
l_elbow 26%) — consistent with the camera framing in the source
recording. Distal joints (wrists, ankles) and face joints are still
near-random, consistent with the 56-subcarrier / 20-frame input not
carrying fine-grained spatial info at 1077 samples.
This commit:
* Adds v2/crates/cog-pose-estimation/cog/artifacts/{pose_v1.safetensors,
train_results.json} so the cog dir now contains a real reference
artifact, not just scaffold.
* Updates cog/README.md "Status" block with the measured numbers,
per-joint table, and an honest reading of where the model
succeeds vs where the data is the bottleneck.
* Adds docs/benchmarks/pose-estimation-cog.md as the canonical
benchmark log — append-only, one section per published run.
* Appends a "First measured run" section to ADR-101 referencing
the new benchmark file.
Still pending in the follow-up:
* Wire pose_v1.safetensors into src/inference.rs (replace stub).
* ONNX export (Candle lacks a writer — needs external conversion).
* Hailo HEF cross-compile + cluster deploy.
The data-bound gap to PCK@20 >= 35% is tracked in #640.
* feat(cog-pose-estimation): wire real weights — cog is no longer a stub
Replaces the centred-skeleton stub in src/inference.rs with a real
Candle-based loader that reads cog/artifacts/pose_v1.safetensors and
runs the trained Conv1d encoder + MLP pose head on every incoming CSI
window.
What changes:
* src/inference.rs: PoseNet mirrors the training script's architecture
exactly — Conv1d(56->64, k=3 d=1), Conv1d(64->128, k=3 d=2),
Conv1d(128->128, k=3 d=4), mean over time, Linear(128->256)+ReLU,
Linear(256->34)+sigmoid -> reshape [17, 2]. The InferenceEngine
searches a sensible candidate list for the weights file
(/var/lib/cognitum/apps/pose-estimation/, ./pose_v1.safetensors,
./cog/artifacts/, repo-root, v2/-relative) and falls back to the
stub when none are present so the cog still satisfies ADR-100.
* Cargo.toml: adds candle-core 0.9 + candle-nn 0.9 (no-default-features,
CPU build by default) + safetensors 0.4. New `cuda` feature opt-in
for GPU inference on hosts that have it. Drops the unused
wifi-densepose-train path dep from the default build path.
* src/main.rs + src/publisher.rs: health.ok event now carries
`backend` (candle-cuda | candle-cpu | stub) and the synthetic
output confidence, so operators can tell at a glance whether the
cog loaded its weights or fell back to the stub.
* tests/smoke.rs: adds `real_weights_load_when_available` which
asserts the loaded engine reports backend=candle-* and emits
non-zero confidence — exactly the signal that proves we're not
silently degrading to the stub.
Verified locally:
* `cargo check -p cog-pose-estimation --no-default-features` — clean
* `cargo test -p cog-pose-estimation --no-default-features` — 5/5 pass
* `./target/release/cog-pose-estimation health` emits:
{"event":"health.ok","fields":{"backend":"candle-cpu","cog":"pose-estimation","synthetic_output_confidence":0.185}}
— 0.185 is the published PCK@50 from cog/artifacts/train_results.json,
emitted by the real Candle inference path (would be 0.0 if it had
fallen back to the stub).
The cog now runs the trained pose_v1 model end-to-end. Accuracy is
still bounded by the underlying 1077-sample training data (PCK@20
3.0%, PCK@50 18.5% per docs/benchmarks/pose-estimation-cog.md) — that
gap is data-bound and tracked in #640. ONNX export + Hailo HEF
cross-compile remain follow-ups.
* docs(benchmarks): measure cog-pose-estimation cold-start latency
100 sequential `cog-pose-estimation health` invocations average 76.2 ms
each on a Windows x86_64 host using the `candle-cpu` backend. Each
invocation re-loads pose_v1.safetensors and runs one synthetic forward
pass, so this is the worst-case cold-start path. Long-running `run`
inference will be sub-millisecond per frame once the model is loaded.
Updates the benchmarks doc accordingly.
* feat(cog-pose-estimation): ONNX export — pose_v1.onnx + scripts/export-onnx.py
Adds the canonical ONNX artifact that unblocks downstream Hailo HEF
cross-compile + ONNX Runtime benchmarks. Generated on ruvultra (torch
2.12.0 + CUDA), 12,059 bytes, opset 18, dynamic batch axis.
* scripts/export-onnx.py: mirrors the Candle inference architecture in
PyTorch (Conv1d 56->64, 64->128, 128->128 + Linear 128->256->34), pure-
python safetensors loader (no extra pip dep), exports via
torch.onnx.export, then verifies via onnx.checker.check_model and
numerical parity against the torch reference.
* Verified parity vs torch: max |torch - onnx| = 8.94e-8 (1e-5
threshold). Effectively bit-perfect.
* v2/crates/cog-pose-estimation/cog/artifacts/pose_v1.onnx — the
artifact itself, 12 KB.
* docs/benchmarks/pose-estimation-cog.md — adds an ONNX export
section with the verification numbers.
Next: Hailo HEF cross-compile (still gated on Hailo SDK on a
self-hosted runner) and ONNX Runtime latency benchmarks on each
target arch.
* feat(cog-pose-estimation): release v0.0.1 — signed aarch64 binary on GCS
End-to-end deploy: cross-compiled to aarch64-unknown-linux-gnu on
ruvultra, ran via qemu-aarch64-static, then smoke-tested on a real
cognitum-v0 Pi 5. Signed with COGNITUM_OWNER_SIGNING_KEY (Ed25519)
and uploaded to gs://cognitum-apps/cogs/arm/.
Real-hardware results on cognitum-v0 (Pi 5):
health: backend=candle-cpu, confidence=0.185, real weights loaded
30x sequential `health`: 0.251 s total -> 8.4 ms / invocation (cold)
GCS release artifacts (publicly downloadable):
binary: 3,741,976 bytes
sha256 1e1a7d3dd01ca05d5bfc5dbb142a5941b7866ed9f3224a21edc04d3f09a99bf5
weights: 507,032 bytes
sha256 eb249b9a6b2e10130437a10976ed0230b0d085f86a0553d7226e1ae6eae4b9e5
signature (Ed25519, b64): LUN7xqLPYD3MFzm5dKB5MnYU0LvoRtek5ci5KiKPHBg+Xo6xuazwokn2Dw2JPMaLYJzmWn/SpT4djuR7hYvVDw==
Adds:
* v2/crates/cog-pose-estimation/cog/artifacts/manifest.json — the
release-pipeline-produced manifest with all fields filled in per
ADR-100, including arch, target_triple, signature, and a
build_metadata block carrying the validation PCK numbers.
* docs/benchmarks/pose-estimation-cog.md — new sections covering
the real Pi 5 smoke (8.4 ms cold-start) and the signed GCS
release artifacts.
Verified by downloading the binary anonymously from GCS and
re-computing the sha256 — matches the locally-computed sha exactly.
Signature decoded to the expected 64-byte Ed25519 length.
Closes the GCS-upload acceptance criterion from ADR-100; the only
pending work is Hailo HEF cross-compile (still SDK-gated) and an
x86_64 release alongside this arm release.
* docs(benchmarks): record live cognitum-v0 install + 5-sec smoke run
Adds the "Live appliance install" section documenting what happened
when the signed v0.0.1 binary + weights were installed under
/var/lib/cognitum/apps/pose-estimation/ on cognitum-v0 (the V0
cluster leader).
* Layout matches the existing anomaly-detect / presence / seizure-
detect cogs exactly — the Cogs dashboard at
http://cognitum-v0:9000/cogs auto-discovers entries.
* `cog-pose-estimation run` ran for 5 seconds in the background and
cleanly emitted run.started + structured WARN events for the
missing local sensing-server on :3000 (cognitum-v0's actual CSI
source is ruview-vitals-worker on :50054, not :3000). No crashes,
no NaN, no leaks.
* Wiring `sensing_url` to the appliance-native source is a separate
Day-2 integration task.
Two blockers discovered while running ADR-079 P7→P8 end-to-end against
a 30-minute paired session (39,088 GT frames + 45,625 CSI frames):
1. `readFileSync(_, 'utf8').split('\n')` hit Node's `String.MaxLength`
(~512 MB) on the 750 MB CSI recording. Result:
Error: Cannot create a string longer than 0x1fffffe8 characters
Replaced loadJsonl with a 1 MiB byte-buffer streaming reader that
decodes line-by-line, so memory use stays bounded by the largest
single record.
2. The sensing-server has long since switched from the legacy `raw_csi`
/ `feature` typed records to a single `sensing_update` record per
tick (with nodes[].amplitude and top-level features). The aligner
filtered on the old types and produced 0 frames every time. Added a
`sensing_update` branch that projects each tick into rawCsi/features
entries the existing windowing code can consume, and updated
extractCsiMatrix to use already-extracted amplitudes when iqHex is
absent. timestamp is now accepted as either ISO string (legacy) or
numeric float-seconds (current).
End-to-end verified: produces 1,077 paired samples at
`--min-confidence 0.3 --window-frames 20` from the full 30-min
recording; downstream `train-wiflow-supervised.js` runs to completion.
See follow-up #640 for the PCK gap (data + GPU needed) — those are
training concerns, not aligner concerns.
The previous wording in both README.md and docs/user-guide.md claimed
no pretrained weights were released yet. That was wrong — the
contrastive CSI encoder + presence-detection head + per-node LoRA
adapters have been published as
ruvnet/wifi-densepose-pretrained on Hugging Face for several weeks
(124 downloads at time of writing), with 100% presence accuracy on
the validation set and 164,183 emb/s on M4 Pro.
This commit replaces the "no shipped weights" framing with the actual
state, and surfaces a real loader gap discovered during a
before/after benchmark of the sensing-server:
* Baseline run (no --model): server produced presence/motion/vitals
output at ~19 ticks/s, as expected.
* After run (--model models/wifi-densepose-pretrained.rvf): the
progressive RVF loader errored with
"invalid magic at offset 0: expected 0x52564653, got 0x7974227B"
(0x7974227B is the ASCII bytes {"ty… from the JSONL header).
v2/.../rvf_container.rs only parses the binary RVF segment
format; the HF artifact is JSONL RVF. When the load fails the
pipeline degraded to null output (variance=0, presence=None) rather
than falling back to heuristic mode.
The docs now describe (a) what works today — Python / training-side
consumption of model.safetensors — and (b) what is gated on a JSONL
adapter or a binary-RVF republish — sensing-server --model loading.
The 17-keypoint pose model remains separately pending (#509,
ADR-079 phases P7–P9).
@xiaofuchen's audit in #568 was technically correct: the project page
claimed capabilities (\"Pose estimation\", \"Presence sensing — trained
model + PIR fusion — 100% accuracy\") that aren't what the code actually
does. PR #573 fixed this in the firmware README; this commit applies
the same truth-up to the main repo README so first-time visitors get
an honest picture.
Specific changes:
1. **Hero paragraph (line 35)** — was \"RuView also supports pose
estimation (17 COCO keypoints …)\" with no caveat. Now: ships the
training infrastructure; pretrained weights are not yet released
(links #509 and ADR-079 P7-P9 Pending).
2. **Capability table (lines 50-61)** — was a single 11-row \"What/How/
Speed\" table that mixed shipped, heuristic, and pipeline-only
capabilities under the same emoji. Now a status column with a
three-tier legend:
- ✅ shipped + tested on hardware (breathing rate, heart rate,
motion, fall detection, through-wall, edge intelligence,
multi-frequency mesh)
- ⚠️ ships and runs, but is a heuristic/threshold (presence
indicator, multi-person slot count) — accuracy depends on
calibration and signal conditions
- 🔬 implementation + tests in repo, weights/data/eval pending
(17-keypoint pose estimation, camera-supervised fine-tune,
3D point cloud fusion)
3. **Hardware capability column (lines 91-93)** — was \"Pose, breathing,
heartbeat, motion, presence\" for the ESP32 options. Replaced with
the literal list of capabilities that actually work today (presence
indicator, motion, breathing, heart rate, fall detection, slot-count
heuristic) with an explicit \"Pose pending weights — see #509\"
qualifier.
Pointing also to the v0.6.5-esp32 release-aligned firmware README that
already has the firmware-side truth-up (PR #573).
This is documentation only — no code change, no behaviour change. The
project's capabilities haven't changed; the project page now describes
them honestly.

#613 fixed adaptive_classifier.rs:94 (the IQR sort) and called the audit
done, but the grep used `partial_cmp(b).unwrap()` as a literal and missed
seven additional production sites that use comparator variants:
adaptive_classifier.rs:205 AdaptiveModel::classify() argmax over softmax
probs — same per-frame hot path as #611.
NaN flows through normalise → logits → softmax
and still reaches this site even after the
IQR fix.
adaptive_classifier.rs:480 train() argmax (training accuracy loop)
adaptive_classifier.rs:500 train() per-class argmax
main.rs:2446, 2449 count_persons_mincut variance source/sink select
csi.rs:602, 605 count_persons_mincut variance source/sink select
(duplicate of main.rs logic in csi.rs)
For the variance-select sites, note that the *outer* `unwrap_or((0, &0))`
only catches an empty iterator — it cannot rescue a panic raised inside
the comparator. A single NaN in `variances[]` still aborts the process.
Same fix as #613: swap `.unwrap()` for `.unwrap_or(std::cmp::Ordering::Equal)`
inside the comparator closure. Pure behavioural change, no API surface.
Re-audit of the remaining `partial_cmp(...).unwrap()` matches in v2/:
they are all inside `#[cfg(test)]` / `#[test]` blocks (spectrogram.rs:269,
depth.rs:234, connectivity.rs:477, vital_signs.rs:737) where inputs are
controlled and panic-on-NaN is acceptable.
PR #547 refreshed the sensing-server docker publish and the README badge
advertises 'Docker: multi-arch amd64 + arm64', but
.github/workflows/sensing-server-docker.yml only sets
'platforms: linux/amd64'. The arm64 layer was never actually wired in.
Consequence on Docker Hub today (ruvnet/wifi-densepose:latest, last pushed
2026-05-14 by #547):
$ curl -s https://hub.docker.com/v2/repositories/ruvnet/wifi-densepose/tags/latest/
images:
arch=amd64 os=linux
arch=unknown os=unknown # the 1.5KB attestation layer, not arm64
So Apple Silicon Macs (the platform in #625) hit:
docker pull ruvnet/wifi-densepose:latest
Error: no matching manifest for linux/arm64/v8 in the manifest list
This is the same crash class as the closed-unmerged #136 'Docker error on
MacOS'; #625 is a fresh report (Mac M3 Pro, macOS Tahoe 26.4.1) of the same
bug.
Fix is the standard buildx multi-arch recipe:
1. Add docker/setup-qemu-action@v3 before setup-buildx so the amd64 runner
can cross-build the arm64 layer (QEMU user-mode emulation).
2. Change 'platforms: linux/amd64' -> 'platforms: linux/amd64,linux/arm64'.
docker/Dockerfile.rust is already arch-agnostic — no '--target' flag, no
amd64-only Cargo deps, only 'cc = "1.0"' which is cross-aware — so no
Dockerfile changes are needed. Buildx + QEMU does the rest.
Smoke tests are unaffected: they 'docker pull' on ubuntu-latest (amd64), so
the runner auto-selects the amd64 entry from the multi-arch manifest.
Multi-arch manifests are transparent to single-arch consumers.
Scope discipline: this PR only touches sensing-server-docker.yml (the file
issue #625 is about). nvsim-server-docker.yml has the identical
'platforms: linux/amd64' bug but is out of scope here — happy to file
a follow-up if useful.
Note (not part of this fix): the last 5 runs of this workflow have failed
at the 'Log in to Docker Hub' step (DOCKERHUB_TOKEN secret looks rotated/
expired). That's a separate, secret-side issue I can't touch from a PR.
Once that's resolved, the next push to main will produce a proper
amd64+arm64 manifest for the first time.

Integrating @schwarztim's PR #491 into main on their behalf — their fork has
fallen too far behind for a clean rebase (the PR's commit graph dropped
silently during `git rebase origin/main`), so applying as a merge from the
fork head to preserve the diff cleanly.
What this lands:
- `RollingP95` adaptive normaliser for the person-count feature scaling.
Streaming P95 over a 600-sample / ~30 s sliding window. Cold-start
(<60 samples) falls back to the legacy denominators (variance/300,
motion_band_power/250, spectral_power/500) so day-0 behaviour is
preserved on every deployment.
- `RuntimeConfig` struct + `load_runtime_config` / `save_runtime_config`
persisted to `data/config.json`. Exposes `dedup_factor` via REST so
multi-node deployments can tune cluster-deduplication without a rebuild,
including an auto-tune endpoint that derives optimal dedup from a known
person count (calibration mode).
- `compute_person_score()` now takes &AppStateInner alongside &FeatureInfo
so the adaptive denominators are reachable. All 3 call sites updated.
- New `AppStateInner` fields: `p95_variance`, `p95_motion_band_power`,
`p95_spectral_power`, `dedup_factor`, `data_dir`.
Closes#491. Directly addresses:
- #499 (double skeletons, multi-node) — the slot-clustering problem this
PR's adaptive normaliser was designed to fix
- #519 Bug 1 (ghost person detection on edge-tier 1 & 2 multi-node)
- #496 (person count over-reporting on single-room single-person)

Three fixes wrapped for the v0.6.5-esp32 release tag:
1. **`sdkconfig.defaults` adds `CONFIG_FREERTOS_TIMER_TASK_STACK_DEPTH=8192`**.
The fix was already in `sdkconfig.defaults.template` (ADR-081, prevents
"stack overflow in task Tmr Svc" bootloop when adaptive_controller emits
feature_state from inside a Timer Svc callback). It was MISSING from the
canonical `sdkconfig.defaults` file used by the build, so any fresh
build picked up the 2 KiB FreeRTOS default and bootlooped on hardware.
Verified on COM7: with the fix, no panics in 30 s of operation; without
it, "***ERROR*** A stack overflow in task Tmr Svc has been detected."
followed by sustained bootloop.
2. **`ota_update.c` extracts `ota_load_psk_from_nvs()` and calls it from
both `ota_update_init()` and `ota_update_init_ex()`.** `main.c:230` uses
the `_ex` variant, but only `ota_update_init()` was loading the PSK
from NVS. Result: `s_ota_psk` stayed empty regardless of NVS contents,
so the RuView#596 fail-closed posture rejected every request — but the
diagnostic warning never printed at boot, leaving operators no signal
about why their OTA uploads were 403'ing. Verified on COM7:
W (3126) ota_update: NVS namespace 'security' not found —
OTA upload endpoint will REJECT all requests until provisioned.
Fail-closed per RuView#596.
3. **`version.txt`: 0.6.4 → 0.6.5**, paired with the v0.6.5-esp32 tag so the
firmware-ci version-guard job (RuView#505 fix-marker) stays happy.
Both validations done end-to-end on hardware (COM7, ESP32-S3 8MB,
provisioned with --edge-tier 2 to also incidentally re-verify #438 is not
reproducible on current main).
ota_check_auth() previously returned true when s_ota_psk[0] == '\0'
("permissive for dev"). A freshly-flashed node — or any node where
nobody had provisioned an OTA PSK yet — accepted attacker-controlled
firmware over plain HTTP on port 8032 from any host on the WiFi. No
Secure Boot V2, no signed-image verification, no transport encryption.
Single LAN call could brick or backdoor a node.
This was flagged in the deep security review of PR #596 but was a
PRE-EXISTING bug in main, not new code from that PR — so it stood as
a critical-severity production issue until this commit.
Fix:
- ota_check_auth() now returns false when no PSK is provisioned, with
ESP_LOGW("OTA rejected: no PSK in NVS …") at the call site so the
operator can diagnose the rejection from serial logs
- ota_update_init() ESP_LOGW message updated to surface the new posture
at boot ("upload endpoint will REJECT all requests until provisioned")
- Doc comment on ota_check_auth() rewritten to make the contract
explicit and reference the audit
The OTA HTTP server itself still starts even when no PSK is set. That
lets the operator run `provision.py --ota-psk <hex>` over USB-CDC to
write the NVS key without reflashing the firmware. The upload endpoint
just refuses every request in the meantime.
Breaking change for any deployment that depended on the unauthenticated
OTA path working out of the box. Documented in CHANGELOG under
[Unreleased] / Security so it's visible at the next release cut.
Fix-marker RuView#596-ota-fail-closed (scripts/fix-markers.json)
requires the new behaviour and forbids the old "permissive for dev"
fallback strings, so a future revert fails CI.
