Fix antenna-regime presence over-read: de-saturate motion_score + correct CSI header offsets

After external IPEX antennas were added to the ESP32-S3 mesh nodes, a confirmed-empty
room read "present" indefinitely. Two root-cause bugs:

1. motion_score saturation. `variance_motion` and `mbp_motion` used fixed divisors
   (/10, /25) calibrated for the antenna-less regime. Antennas raised amplitudes ~5x
   and these amplitude^2 energies ~30x, pinning both terms at the 1.0 clamp — so
   raw_motion could not fall near the presence floor and the adaptive baseline
   subtraction in smooth_and_classify was defeated. Normalize both by signal power
   (mean_amp^2) — the same dimensionless sqrt-of-power-ratio form already used by
   temporal_motion_score — making motion_score amplitude-scale-invariant. This fixes
   the single shared extract_features_from_frame used by BOTH the aggregate and the
   per-node paths, so room-level presence benefits too. (csi.rs carries the identical
   change in its dead mirror copy to keep the two in sync.)

2. parse_esp32_frame header offsets were 2 bytes early vs the firmware layout
   (csi_collector.c csi_serialize_frame: seq @ [12..16), rssi @ [16], noise_floor @
   [17]). rssi was decoded from sequence-counter byte 2 — which stays 0 for the first
   65,536 frames — yielding an impossible rssi=0 dBm that zeroed the RSSI fusion
   weights and the SNR-based signal_quality. The I/Q payload at byte 20 was already
   correct (CSI_HEADER_SIZE == 20), so amplitude-derived features were unaffected.

Adds regression tests asserting motion_score is amplitude-scale-invariant and that a
quiet high-amplitude signal does not saturate. Full binary suite green (103 tests).

Validated live on the 2-node mesh: RSSI now reports real values (-28..-74 dBm, was 0)
and an empty room now produces genuine low-motion frames. A residual over-read remains
(real multi-subcarrier CSI reads elevated even when empty) — that intrinsic empty-vs-
still ambiguity needs a learned reference (adaptive classifier retrain), tracked separately.

 ## [Unreleased]
 
+### Fixed
+- **Person count no longer leaks up to 10 in heuristic mode — addresses #894.** `field_bridge::occupancy_or_fallback` returned the eigenvalue-based `FieldModel::estimate_occupancy` count **unbounded** (its internal ceiling is 10), while the sibling estimators on the same single-link data — the perturbation-energy fallback right below it and `score_to_person_count` — both cap at 3 ("1-3 for single ESP32"). On noisy / under-calibrated CSI the eigenvalue count inflated, producing the "10 persons reported when 1 present" symptom (seen when `--model` fails to load and the server runs on heuristics). Bounded the eigenvalue path to the shared `MAX_SINGLE_LINK_OCCUPANCY` (3) so every estimator on one link agrees; genuine higher counts come from the multistatic fusion path, not a single-link covariance estimate.
+- **MQTT multi-node deployments now create one Home-Assistant device per node — closes #898.** After the #872 MQTT wiring landed, the JSON→`VitalsSnapshot` bridge hard-coded a single `node_id` (the MQTT client id) and the publisher used a single `OwnedDiscoveryBuilder`, so every physical node collapsed into one device (`identifiers:["wifi_densepose_wifi-densepose-1"]`), contradicting the "one device per node" docs. The bridge now emits one snapshot per node in the sensing update's `nodes[]` (each with its own `node_id` + RSSI, falling back to a single aggregate snapshot for wifi/simulate sources), and the publisher derives a per-node builder (`OwnedDiscoveryBuilder::for_node`) that publishes discovery + availability lazily on first sight of each `node_id` and routes state to per-node topics — yielding N distinct HA devices with per-node availability/LWT. Unit-tested (distinct nodes → distinct `wifi_densepose_<node>` identifiers); 71 MQTT tests pass.
+- **Person count no longer pinned to 1 — addresses #803.** The aggregate occupancy reported by the sensing server was derived from `smoothed_person_score`, an EMA-smoothed *activity* score (amplitude variance / motion / spectral energy). That score saturates near a single occupant — one moving person maxes it out — so it cannot discriminate occupancy *count* and stayed clamped at 1 across S3/C6 and the Python/Docker/Rust servers. Meanwhile the count-aware per-node estimates the ESP32 paths already compute (firmware `n_persons`, and the DynamicMinCut `corr_persons`) were stashed in `NodeState::prev_person_count` and then **discarded** by the aggregator (same dead-wiring class as #872). The aggregator now takes `max(activity_count, node_max)` via a unit-tested `aggregate_person_count` helper, so a node positively estimating 2–3 occupants is surfaced instead of overwritten. The fix can only ever *raise* the count when a node reports more people, so the single-occupant case is provably never inflated (regression-guarded by test). **Second half:** the pure-CSI per-node path itself clamped its own estimate — the DynamicMinCut occupancy (`estimate_persons_from_correlation`, 0–3) was mapped to a score via `corr_persons / 3.0`, putting 2 people at 0.667, *just under* the 0.70 up-threshold of `score_to_person_count`, so the per-node count never climbed past 1 (so `node_max` was also stuck at 1 for CSI-only nodes). Replaced it with a threshold-aligned `corr_persons_to_score` mapping (1→0.40, 2→0.74, 3→0.96) whose steady state round-trips back to the same count through the EMA + hysteresis, while still gating transient noise. A convergence test replays the exact EMA loop to prove min-cut=2 now reports 2 (and documents that the old `/3.0` mapping reported 1). Full multi-person accuracy still depends on the underlying estimator quality; this removes the two server-side clamps that masked it. 586 sensing-server tests pass.
+- **MQTT publisher now actually runs (`--mqtt`) — closes #872.** The `--mqtt*` flags were defined only in `cli::Args` (dead code, referenced nowhere) while the binary parses a *separate* `main::Args` with no mqtt fields, and `main.rs` never started the `mqtt::` publisher — so MQTT/Home-Assistant integration was completely unwired (`--mqtt` errored as an unexpected argument, and even with the Docker image's `--features mqtt` build the publisher never ran). Earlier attempts chased a Docker *rebuild*; the real cause was disconnected *code*. Extracted the flags into a shared `cli::MqttArgs` (`#[command(flatten)]` into both structs), spawn the publisher on `--mqtt`, and bridge the JSON sensing broadcast into the typed `VitalsSnapshot` stream with a defensive `serde_json::Value` mapping. Verified end-to-end against `mosquitto`: 20 HA auto-discovery entities + live state (presence/person-count/…). 577 (default) / 580 (`--features mqtt`) tests pass.
+- **Mass Casualty triage never reports a survivor with a heartbeat as Deceased (safety) — PR #926.** Both triage paths in `wifi-densepose-mat` — `TriageCalculator::calculate` (`combine_assessments(Absent, None) ⇒ Deceased`) and the detection path `EnsembleClassifier::determine_triage` (`!has_breathing && !has_movement ⇒ Deceased`) — ignored the `heartbeat` field. A survivor with a detectable **pulse** but no sensed breathing/movement (respiratory arrest — the most time-critical *savable* state, Immediate/Red) was therefore reported **Deceased (Black)** and deprioritized for rescue. The domain path was in fact only reachable *because* a heartbeat made `has_vitals()` true, so every "Deceased" was a live person. Both paths now escalate to **Immediate** when a heartbeat is present; total absence of breathing, movement *and* heartbeat is unchanged (domain → `Unknown`, ensemble → `Deceased`). 2 safety regression tests; full MAT suite (177) green.
+- **Per-node Home-Assistant devices now report each node's *own* presence/motion — PR #918.** After the one-device-per-node fan-out landed, the MQTT bridge still applied the *room-level aggregate* `classification` to every node, so in a multi-node deployment a node watching an empty corner inherited another node's "present" (and `motion_level: "absent"` was mis-mapped to full motion). Each node in the broadcast `nodes[]` already carries its own `classification`; the bridge now reads it per node (extracted into a testable `vitals_snapshots_from_sensing_json`), keeping vitals + person count room-level. 4 unit tests.
+- **`--model` gives an actionable diagnostic instead of a cryptic magic error — PR #919 (refs #894).** Passing a HuggingFace `ruvnet/wifi-densepose-pretrained` file (`model.safetensors` / `model-q4.bin` / `model.rvf.jsonl`) to `--model` produced `invalid magic at offset 0: … got 0x77455735`, then a silent fall back to heuristics. The load-failure path now detects the format (safetensors / quantized blob / JSONL manifest) and explains that those files are a different format **and** encoder architecture than the RVF binary container the progressive loader expects, pointing to #894. Pure `diagnose_model_load_error` + 4 tests.
+- **`--export-rvf` no longer silently produces a placeholder model — PR #920.** The `--export-rvf` handler ran *before* `--train`/`--pretrain` and unconditionally wrote placeholder sine-wave weights, so the documented `--train … --export-rvf <path>` workflow short-circuited to a fake model and never trained (while printing "exported successfully"). It now emits the placeholder **container-format demo** only standalone (with a clear warning), and falls through to real training when `--train`/`--pretrain` is set; docs point to `--save-rvf` for the real model. 3 guard tests.

 ### Added
-- **ADR-147 — OccWorld world model integration** (`wifi-densepose-worldmodel` v0.3.0). Adds a 15-frame trajectory prediction engine running locally on RTX 5080 at 209 ms / 3.37 GB VRAM peak. New Rust crate provides `OccWorldBridge` thin client over Unix socket; Python inference server in `scripts/occworld_server.py` runs OccWorld TransVQVAE (72.4M params) with API-bug patches applied. Kalman tracker (`pose_tracker.rs`) gains `trajectory_prior` soft-blend injection (80/20). See [ADR-147](docs/adr/ADR-147-nvidia-cosmos-world-foundation-model-integration.md) · [benchmark proof](docs/adr/ADR-147-benchmark-proof.md).
+- **WiFi-CSI pose: efficiency frontier + per-room calibration service** (ADR-150 §3.2–3.6). Two beyond-SOTA results on the MM-Fi benchmark, plus the deployment mechanism that resolves real-world generalization:
+  - **Efficiency frontier** — a **75 K-param model beats published SOTA** (74.3% vs MultiFormer 72.25% torso-PCK@20); every config from `micro` up is Pareto-dominant (smaller *and* more accurate than prior work). Shipped a deployable **int4 edge model (~20 KB, verified 74.08%, 0.135 ms single-thread CPU)** — published at [`ruvnet/wifi-densepose-mmfi-pose/edge`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose). See [`docs/benchmarks/wifi-pose-efficiency-frontier.md`](docs/benchmarks/wifi-pose-efficiency-frontier.md).
+  - **Generalization solved by few-shot calibration** — zero-shot cross-subject (~64%) and cross-environment (~10%) are *not* closeable by algorithms (CORAL, DANN, instance-norm, contrastive foundation-pretraining all tested, all failed) or by more training subjects (saturates ~64%). But **~100–200 labeled in-room samples recover SOTA-level pose**: cross-subject 64→76%, **cross-environment 10→73% (60% from just 5 samples)** — deployable as a **~11 KB per-room LoRA adapter** on a frozen shared base. Full empirical chain in ADR-150 §3.2–3.6.
+  - **Calibration service (complete, both model paths, cross-language verified)** — `aether-arena/calibration/`: `calibrate.py` (transformer model, `.npz` adapter) + `infer.py` (verified 3.09%→74.29% on an unseen MM-Fi room), **and `cog_calibrate.py`** which fits a `fc1.a/fc1.b/fc2.a/fc2.b` **safetensors** adapter for the deployed cog conv+MLP model (`pose_v1.safetensors`). Consumed by the Rust product engine: `InferenceEngine::with_adapter()` + `cog-pose-estimation run --config <cfg> --adapter <room.safetensors>`. Self-contained regression tests for both Python producers (`test_calibration.py`, `test_cog_calibration.py`) **plus a cross-language Rust integration test** that loads a real `cog_calibrate.py`-generated adapter fixture and asserts it activates + changes engine output. All green.
+- **Windows workspace build + test now green** (cross-platform fixes). `wifi-densepose-worldmodel` imported `tokio::net::UnixStream` unconditionally, so `cargo build/test --workspace` failed to compile on Windows (E0432) — now the OccWorld Unix-socket bridge is `#[cfg(unix)]`-gated with a clear non-unix fallback. And `wifi-densepose-bfld`'s `readme_quickstart_uses_canonical_public_api` test checked a multi-line `pipeline\n    .process` needle that never matched on a CRLF checkout — now normalizes line endings. Result: **2,682 workspace tests pass / 0 fail on Windows** (the pre-merge gate was previously unrunnable there).
+- **`ruview-swarm` crate (ADR-148)** — drone swarm control system with hierarchical-mesh topology, Raft consensus, MAPPO multi-agent reinforcement learning, and CSI sensing integration. 14 modules: topology (Raft/Gossip/Mesh), formation control (virtual-structure/leader-follower/Reynolds flocking), RRT-APF path planning, auction+FNN task allocation, MARL actor + PPO training loop, security (MAVLink v2 HMAC-SHA256 signing, UWB anti-spoofing, geofencing, Remote ID, FHSS anti-jamming), 10-state fail-safe machine, and SwarmOrchestrator. ITAR-gated coordination features (USML Category VIII(h)(12)) behind `itar-unrestricted` feature.
+- **Ruflo integration for `ruview-swarm`** — feature-gated (`ruflo`) AI-agent capability layer connecting to the claude-flow daemon: AgentDB mission memory (`memory_store`/`memory_search`), HNSW pattern learning (`agentdb_pattern-store`/`-search`), AIDefence MAVLink message scanning, and SONA intelligence trajectory hooks. `RufloBackend` trait with `HttpRufloBackend` (JSON-RPC 2.0) and `MockRufloBackend` implementations.
+
+### Performance
+- `ruview-swarm` benchmarks (criterion, release): MARL actor inference 3.3 µs, RRT-APF planning 0.043 ms, multi-view CSI fusion 58.5 ns, 3-view localization 1.732 m (beats Wi2SAR 5 m SOTA baseline), 4-drone SAR coverage 223 s for 400×400 m (under 240 s target).
+
+### Added
+- **ADR-147 — OccWorld world model integration** (`wifi-densepose-worldmodel` v0.3.0 published to crates.io). 15-frame trajectory prediction at 209 ms / 3.37 GB VRAM on RTX 5080. Phase 3 domain adapter `scripts/ruview_occ_dataset.py` (`RuViewOccDataset`) converts WorldGraph snapshots to OccWorld tensors with indoor class remapping + zero ego-poses (validated). Phase 5 retraining pipeline `scripts/occworld_retrain.py` — VQVAE + transformer fine-tuning on RuView occupancy snapshots. See [ADR-147](docs/adr/ADR-147-nvidia-cosmos-world-foundation-model-integration.md) · [benchmark proof](docs/adr/ADR-147-benchmark-proof.md).
 
 ### Added
 - **ADR-125 (APPLE-FABRIC) — RuView ↔ Apple Home native HAP bridge proposal + reference impl** (issue #796). New ADR-125 lays out a three-phase plan to expose RuView as a discoverable HomeKit accessory on the LAN so a HomePod (as Home Hub) sees presence / vitals / BFLD-derived events natively — zero Home-Assistant intermediary. Two architectural decisions resolved in the ADR per design review: (1) **one HAP bridge with N child accessories** (single pairing, matches Hue/Eve pattern), and (2) **identity-risk mapping is semantic, not probabilistic** — `identity_risk_score` and Soul-Signature match probability never cross the HAP boundary; instead three thresholded events are exposed (`Unknown Presence`, `Unexpected Occupancy`, `Unrecognized Activity Pattern`) so RuView reads as calm-tech ambient awareness, not surveillance UX. ADR-125 §2.1.a reference impl ships now: `scripts/hap-test-sensor.py` (HAP-1.1 bridge advertised over mDNS, paired with operator's iPhone) + `scripts/c6-presence-watcher.py` (parses ESP32 `RV_FEATURE_STATE_MAGIC = 0xC5110006` UDP packets with IEEE CRC32 validation, hysteresis, and a Python port of `wifi-densepose-bfld::PrivacyClass` that enforces ADR-125 §2.1.d invariant I1 at the HomeKit edge — only `Anonymous` (2) and `Restricted` (3) frames may cross; `Raw`/`Derived` are refused with exit code 2 and the cited ADR clause). Validated end-to-end on real hardware (no mocks): ESP32-C6 on `ruv.net` → UDP/5005 → mac-mini watcher → BFLD gate → HAP bridge → iPhone Home app shows `Unknown Presence` live characteristic flip. **Empirical**: 50-51 valid CRC-passing feature_state packets per 10 s window from the live C6; zero CRC errors. P2 (Rust-native HAP via the `hap` crate, replaces the Python sidecar) and P3 (Matter Controller once `matter-rs` stabilizes) follow.
 
 ### Security
 - **ESP32 OTA upload now fails closed when no PSK is provisioned** (#596 audit finding — critical, **breaking change for unprovisioned nodes**). `ota_check_auth()` previously returned `true` when `s_ota_psk[0] == '\0'`, so a freshly-flashed node would accept attacker-controlled firmware over plain HTTP on port 8032 from any host on the WiFi. No Secure Boot V2, no signed-image verification — a single LAN call could brick or backdoor a node. The fix rejects every OTA upload until a PSK is written to NVS (the OTA HTTP server still starts so operators can run `provision.py --ota-psk <hex>` over USB-CDC without reflashing). **Operators affected**: any deployment that relied on the unauthenticated OTA endpoint working out of the box now needs to provision a PSK before subsequent OTA pushes will succeed. Boot-time `ESP_LOGW` makes the new posture visible.
+- **Bearer-token auth accepts the scheme case-insensitively (RFC 6750) — PR #929.** `require_bearer` parsed the `Authorization` header with a case-sensitive `strip_prefix("Bearer ")`, so a *correct* `RUVIEW_API_TOKEN` sent as `Authorization: bearer <token>` (or `BEARER`, or with extra whitespace) was rejected with a confusing 401 — needless friction when enabling auth. The scheme is now matched with `eq_ignore_ascii_case` (per RFC 6750 §2.1 / RFC 7235 §2.1); the token compare is unchanged — still exact and constant-time (`ct_eq`) — so a wrong token or a non-Bearer scheme (`Basic …`) still returns 401. Audited the surrounding code while here: `ct_eq` correctly rejects length mismatch (no prefix-auth bypass) and the middleware fails closed. New `accepts_case_insensitive_bearer_scheme` test.
 - **Path-traversal vulnerabilities patched in five sensing-server endpoints** (closes #615 — critical). New `wifi_densepose_sensing_server::path_safety::safe_id()` enforces `[A-Za-z0-9._-]` only (no leading `.`, max 64 chars) before any user-controlled identifier reaches a `format!()` building a filesystem path.

+- Presence detection: 100% accuracy on 60,630 overnight samples. *(Retracted — that recording was single-class (one sleeping person, 6,062/6,063 frames "present"), so a constant "yes" scores ~99.98%. Superseded by the honest 82.3% held-out temporal-triplet metric; see [#882](https://github.com/ruvnet/RuView/issues/882). Kept here as the in-place public record.)*

+# AetherArena ("AA") — The Official Spatial-Intelligence Benchmark
+
+> **Public leaderboard. Private evaluation split. Open scorer. Signed results.**
+
+AetherArena is a **standalone, project-agnostic benchmark** for camera-free **spatial intelligence** — pose, presence, occupancy, tracking, and vitals from RF/WiFi (and, over time, mmWave / UWB / radar / lidar / multimodal). It is **not** a single-vendor leaderboard: any team, framework, or sensing modality can enter, and every entrant — including the RuView baseline that donated the seed scorer — is scored by the identical, open, pinned harness.
+
+Specified in [ADR-149](../docs/adr/ADR-149-public-community-leaderboard-huggingface.md) (Accepted).
+
+Canonical home: **`ruvnet/aether-arena`** + a Hugging Face Space (deploy pending — see `STATUS`).
+
+---
+
+## Why
+
+WiFi/RF spatial sensing has no shared yardstick — papers self-report against inconsistent splits and metrics, with **no accounting for latency, reproducibility, or privacy leakage**. AA fixes the *measurement*, not just the models: a single deterministic scorer, a private held-out split nobody can train on, and a signed result ledger that can't be silently edited.
+
+## What gets measured (v0)
+
+| Category | Metric | Status |
+|----------|--------|--------|
+| **Pose** | PCK@0.2 (all / torso), OKS | Ranked |
+| **Presence** | accuracy, FP/FN | Ranked |
+| **Edge latency** | p50 / p95 / p99 ms | Ranked |
+| **Determinism** | proof-hash pass/fail | Ranked (gate) |
+| Tracking (MOTA) | — | activates when multi-person clips land |
+| Vitals (BPM err) | — | activates when paired vitals ground truth lands |
+| **Privacy leakage** | membership-inference ∈ [0,1] | **gated — not ranked** until the attacker ships |
+| Cross-room | degradation ratio | coming soon |
+
+The headline rank is the **category metric**; an optional `arena_score = quality × latency_factor × privacy_factor × determinism_gate` is exposed alongside (never instead) so accuracy can't win at any cost. See ADR-149 §2.5.
+
+## How scoring works
+
+The scorer is RuView's **already-published** `wifi-densepose-train` acceptance harness (`ruview_metrics` + ADR-145 `ablation`), run in a pinned sandbox. **You submit a model, not predictions** — predictions on data you hold prove nothing. Your model is scored against a **private** MM-Fi held-out split (CC BY-NC 4.0; Wi-Pose excluded for redistribution reasons), and one **signed, append-only** row is written to the results ledger with a determinism proof hash.
+
+Submission lifecycle: `submitted → validated → quarantined → smoke_scored → full_scored → published` (or `rejected` with a reason). The model only ever runs inside a no-network, read-only-FS sandbox.
+
+## Submit (when the Space is live)
+
+1. Write a manifest: [`schema/aa-submission.toml`](schema/aa-submission.toml).
+2. Push your model artifact (`.safetensors` / `.rvf` / LoRA adapter) + manifest to the Space.
+3. Watch it move through the lifecycle; your signed row appears on the board.
+
+## Verify it's fair (you don't have to trust us)
+
+See [`VERIFY.md`](VERIFY.md) — run the **open scorer** locally on the **public smoke split**, reproduce the determinism hash, and confirm RuView's own entries were scored by the identical path. That five-step check is the launch gate (ADR-149 §7).
+
+## Neutrality
+
+AA is a neutral commons. The scorer is open and versioned; any metric change is a public `harness_version` bump that **re-scores all entries**. RuView donated the seed harness and enters as one baseline — it gets no special treatment (ADR-149 §2.8).

+
+## Blockers / decisions needed
+- **HF deploy (M6)** — token is in GCP Secret Manager (`HUGGINGFACE_API_KEY`); creating the public `ruvnet/aether-arena` Space still wants explicit go.
+- **MM-Fi is CC BY-NC** → AA must stay non-commercial / legally distinct from the commercial RuView product.

+# Verifying AetherArena (you don't have to trust us)
+
+AA's credibility rests on a stranger being able to reproduce a score and see that the rules are fair. This is the **launch gate** (ADR-149 §7): v0 does not ship until all five checks below pass for someone with no insider access.
+
+> **Wider context:** this page covers the *leaderboard scorer*. For the whole-platform answer to
+> "is this real / does it actually work?" — including the deterministic pipeline proof, the
+> published models + public-benchmark numbers, and the built-in-public development trail — see
+> [`docs/proof-of-capabilities.md`](../docs/proof-of-capabilities.md).
+
+## The open scorer
+
+The scoring engine is a pure-Rust, GPU-free binary: `aa_score_runner` in `wifi-densepose-train`. It runs the real `ruview_metrics` pose-acceptance harness on a fixed fixture and emits a cross-platform-stable SHA-256 **determinism proof**.
+
+### Reproduce the determinism hash locally
+
+```bash
+cd v2
+# Verify the committed expected hash still matches (this is the CI gate):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features
+# → prints the witness (inputs_sha256 + proof_sha256) and "VERDICT: PASS"
+
+# See the witness row as JSON:
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --json
+```
+
+### Witness chain — proof + repeatability analysis
+
+Every score is a **witness**: `inputs_sha256` (binds it to the exact inputs scored)
++ `proof_sha256` (cross-platform-stable hash of the quantised score) + `harness_version`.
+Witnesses are recorded in an **append-only, hash-chained ledger** (each row references
+the previous row's hash), so a silent edit to any past row breaks the chain.
+
+```bash
+# Repeatability: run the scorer K times, confirm ONE identical proof hash:
+cd v2
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16
+# → {"repeatability":{"runs":16,"unique_proof_hashes":1,"repeatable":true,...}}
+
+# Real model scoring (score predictions against an eval split):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- \
+  --split ../aether-arena/fixtures/smoke_split.json \
+  --pred  ../aether-arena/fixtures/smoke_pred.json --json
+
+# Verify the witness ledger chain is intact (tamper-evident):
+cd ../aether-arena/ledger && python3 ledger_tools.py verify
+# → "OK: N rows, chain intact"   (edit any row and it reports the broken link)
+```
+
+The expected hash is committed at [`fixtures/expected_score.sha256`](fixtures/expected_score.sha256). Same harness version + same fixture → same hash on glibc / MSVC / Apple. If your local run prints `VERDICT: PASS`, you have reproduced the scorer.
+
+### What happens if the scoring maths changes
+
+Any edit to `ruview_metrics.rs`, `ablation.rs`, or `aa_score_runner.rs` moves the hash and **fails the CI gate** (`.github/workflows/aether-arena-harness.yml`) until the maintainer regenerates and reviews:
+
+```bash
+cargo run -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --generate-hash \
+  > aether-arena/fixtures/expected_score.sha256
+```
+
+So a scorer change is always a reviewed, public diff — never silent. That's `harness_version` pinning + `determinism_gate` in action (ADR-149 §2.4–§2.5).
+
+## The five-step acceptance test (v0 launch gate)
+
+A stranger must be able to:
+
+1. **Submit** a model (artifact + `schema/aa-submission.toml`) with no insider help.
+2. **Get a deterministic score** — same model + same `harness_version` → same numbers.
+3. **See the signed row** appended to the public results ledger.
+4. **Rerun the scorer locally** on the public smoke split and reproduce the logic (the command above).
+5. **Understand why the rank is fair** — private split, open scorer, pinned version, proof hash — from these docs alone.
+
+If any step fails, v0 is not ready.
+
+## Current status
+

+# RuView Calibration Service (reference implementation)
+
+Turn a **shared WiFi-CSI pose base model** into a room-specific one with a **30-second labeled
+calibration** and a **~11 KB per-room LoRA adapter**. This is the deployable resolution of the
+cross-subject / cross-environment generalization problem (full study: [ADR-150 §3.3–3.6](../../docs/adr/ADR-150-rf-foundation-encoder.md)).
+
+## Why
+
+Zero-shot WiFi pose generalizes poorly to a **new room or new person** — an unseen room can drop a
+strong model to near-random. But that gap is **not** algorithmically closeable (CORAL, DANN,
+instance-norm, contrastive foundation-pretraining all failed) and **not** closeable by collecting
+more subjects (saturates ~64%). It **is** closeable, cheaply, at deployment time: a handful of
+labeled frames from the actual room pin down its multipath instantly.
+
+| Deployment case | Zero-shot | + in-room calibration |
+|-----------------|----------:|----------------------:|
+| Same room, new person (cross-subject) | 64% | **76%** (200 samples) |
+| **New room + new person (cross-environment)** | **~10%** | **60% @ 5 samples → 73% @ 200** |
+
+**Verified demo (this code, source-only base on an unseen MM-Fi room E04):**
+`zero-shot 3.09% → after 200-sample calibration 74.29%` (+71 pts).
+
+## How it works
+
+A frozen shared **base** (transformer + temporal attention pool + skeleton-graph head, the published
+[`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose)) plus a
+tiny **LoRA adapter** (rank 8 on the input projection + pose head — **11,200 params ≈ 11 KB int8 /
+22 KB fp16**) fitted per room. Thousands of room-adapters hang off one base.
+
+## Usage
+
+```bash
+# 1) Capture a short labeled clip in the deployment room -> calib.npz {X:[N,3,114,10], Y:[N,17,2]}
+#    (~100–200 samples recommended; below ~20 the adapter can underperform zero-shot)
+
+# 2) Fit the per-room adapter (~11 KB):
+python calibrate.py --base pose_mmfi_best.pt --data calib.npz --out room.adapter.npz
+
+# 3) Run calibrated inference (base + room adapter):
+python infer.py --base pose_mmfi_best.pt --adapter room.adapter.npz --data frames.npz --out kp.npy
+#    omit --adapter to run the uncalibrated (zero-shot) base
+```
+
+`X` is CSI amplitude `[N, 3 antennas, 114 subcarriers, 10 frames]` (per-sample standardization is
+applied internally). `Y` is `[N,17,2]` COCO keypoints in `[0,1]`.
+
+## Calibration budget (measured, rank-8 LoRA, 3 seeds — ADR-150 §3.5)
+
+| Labeled samples/room | cross-subject | cross-environment |
+|---------------------:|--------------:|------------------:|
+| 0 (zero-shot) | 64% | ~10% |
+| 5 | — | 60% |
+| 20 | 66% | 66% |
+| 50 | 70% | 70% |
+| 200 | 72% | 73% |
+
+Knee at ~50 samples (~70%); **below ~20 samples the adapter can hurt** (too few to fit reliably).
+
+## Two models, two producers (not interchangeable)
+
+Adapters are **model-specific**. There are two calibration producers here:
+
+| Producer | Target model | Input | Adapter format | Consumer |
+|----------|--------------|-------|----------------|----------|
+| `calibrate.py` | MM-Fi **transformer** (`pose_mmfi_best.pt`, 3×114×10) | `[N,3,114,10]` | `.npz` (`proj`/`head` LoRA) | this Python `infer.py` |
+| `cog_calibrate.py` | cog **conv+MLP** (`pose_v1.safetensors`, 56×20) | `[N,56,20]` | `.safetensors` (`fc1.a`/`fc1.b`/`fc2.a`/`fc2.b`) | Rust `cog-pose-estimation run --adapter` |
+
+```bash
+# Produce a cog-format per-room adapter for the deployed Rust pose engine:
+python cog_calibrate.py --base pose_v1.safetensors --data calib.npz --out room.safetensors
+# then in the cog runtime:
+cog-pose-estimation run --config <cfg> --adapter room.safetensors
+```
+
+Same LoRA *mechanism* (ADR-150 §3.5), different architecture and key layout — an adapter from one
+producer will not load into the other model.
+
+## Notes
+
+- **Calibration only helps when the base hasn't already seen the room.** The published flagship was
+  trained on MM-Fi `random_split`, so calibrating it on an MM-Fi subject is a near-no-op (it already
+  saw them); for a genuinely new real-world room it is zero-shot and calibration applies. To
+  *reproduce the demo* on a held-out MM-Fi room, train a source-only base (exclude the target
+  environment) — see `ADR-150 §3.6` and the few-shot harness in `aether-arena/staging/`.
+- Adapter is saved fp16 (~22 KB); quantize to int8 for the ~11 KB on-device form.
+- Inference is real-time on CPU (the 75 K-param `micro` variant runs in 0.135 ms single-thread x86;
+  see [`docs/benchmarks/wifi-pose-efficiency-frontier.md`](../../docs/benchmarks/wifi-pose-efficiency-frontier.md)).

+Each row is hash-chained to the previous one: ``row_hash = sha256(canonical_row

+# AetherArena ("AA") — The Official Spatial-Intelligence Benchmark
+
+> Public leaderboard. Private evaluation split. Open scorer. Signed results.
+
+The field's standard yardstick for camera-free **spatial intelligence** (pose, presence,
+occupancy, tracking, vitals) from RF/WiFi and, over time, mmWave / UWB / multimodal.
+
+- **Project-agnostic** — any team, framework, or modality enters; RuView donated the seed
+  scorer and is scored like everyone else.
+- **Benchmark-first** — the board starts empty; every row is a real scoring-pipeline
+  **witness** (`inputs_sha256` + `proof_sha256` + `harness_version`) in an append-only,
+  hash-chained, tamper-evident ledger.
+- **Reproducible** — the scorer is open; reproduce any proof hash + repeatability locally.
+
+Spec: [ADR-149](https://github.com/ruvnet/RuView/blob/main/docs/adr/ADR-149-public-community-leaderboard-huggingface.md).
+Source + open scorer: https://github.com/ruvnet/RuView/tree/main/aether-arena
+
+Non-commercial (CC BY-NC 4.0): the v0 eval split derives from MM-Fi (CC BY-NC); AA is operated non-commercially.

+ABOUT = """
+**AetherArena** is the official, project-agnostic **Spatial-Intelligence Benchmark** —
+camera-free pose, presence, occupancy, tracking, and vitals from RF/WiFi (and, over
+time, mmWave / UWB / radar / multimodal). It is **not** a single-vendor board: any
+team, framework, or modality enters, and every entrant — including the RuView baseline
+that donated the seed scorer — is scored by the identical, open, pinned harness.
+
+The scorer reuses RuView's released `wifi-densepose-train` acceptance harness
+(`ruview_metrics` + ablation). You submit a **model, not predictions**; it is scored
+against a **private** MM-Fi held-out split; one **witness** row (inputs hash + proof
+hash + harness version) is appended to a **hash-chained, tamper-evident ledger**.
+
+**For industry:** a vendor-neutral, auditable way to compare RF-sensing models on equal
+footing — the same standardized splits, the same metric definition, the same signed,
+reproducible ledger. No more "trust our number on our split." Vendors, labs, and startups
+all submit through one pipeline and are scored identically.
+
+**Generalization Track (roadmap):** the headline isn't a single in-domain number — it's a
+battery of honest tracks: MM-Fi `random_split` (in-domain), `cross_subject` (unseen people),
+cross-room, cross-device, and confidence-calibration (ECE). Cross-subject is the real
+deployment frontier and is treated as the flagship hard benchmark.
+
+Spec: ADR-149. v0 ranks **pose, presence, edge-latency, determinism**. Tracking &
+vitals activate when their ground truth lands; **privacy-leakage** is gated until the
+membership-inference attacker ships. Source + the open scorer:
+https://github.com/ruvnet/RuView/tree/main/aether-arena
+"""
+
+SUBMIT = """
+### Submit a model
+
+1. Write a manifest — [`schema/aa-submission.toml`](https://github.com/ruvnet/RuView/blob/main/aether-arena/schema/aa-submission.toml):
+   declare your model ref, category, the ADR-145 feature set (F0 CSI … F3 BFLD), and the tensor I/O contract.
+2. Provide your model artifact (`.safetensors` / `.rvf` / LoRA adapter).
+3. It moves through `submitted → validated → quarantined → smoke_scored → full_scored → published`,
+   scored in a no-network, read-only sandbox against the private split.
+4. Your signed witness row appears on the leaderboard.
+
+**You submit a model, never predictions** — predictions on data you hold prove nothing.
+"""
+
+VERIFY = """
+### Verify it's fair (you don't have to trust us)
+
+The scorer is open and reproducible. Reproduce the determinism proof + repeatability locally:
+
+```bash
+git clone https://github.com/ruvnet/RuView && cd RuView/v2
+# determinism gate (same as CI):
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features
+# repeatability — N runs, one identical proof hash:
+cargo run -q -p wifi-densepose-train --bin aa_score_runner --no-default-features -- --repeat 16
+# verify the append-only witness ledger chain:
+cd ../aether-arena/ledger && python3 ledger_tools.py verify
+```
+
+A stranger must be able to: submit → get a deterministic score → see the signed row →
+rerun the scorer locally → understand why the rank is fair. That is the launch gate (ADR-149 §7).

+
+> **Scope note:** AetherArena is a **standalone, project-agnostic benchmark** for spatial intelligence — open to *any* project, team, or modality, not a RuView-branded board. RuView contributes the initial scoring harness and enters as one baseline among others; it gets no special treatment. This ADR lives in the RuView repo only because RuView is donating the seed harness — the benchmark itself is independent.

+| **Gate decisions** | Name **locked**: `ruvnet/aether-arena` ("AA"), positioned as the official cross-project Spatial-Intelligence Benchmark. v0 ranked metrics **locked**: pose, presence, edge-latency, determinism. Dataset legality **resolved**: MM-Fi (CC BY-NC 4.0) only for v0; Wi-Pose dropped (research-use, no redistribution). |

+
+---
+
+## 1. Context
+
+### 1.1 The Gap
+
+RuView has a mature, deterministic evaluation surface but **no public face for it**. Two assets already exist:
+
+1. **A grading harness.** `wifi-densepose-train/src/ruview_metrics.rs` rolls pose (PCK@0.2 / OKS / torso jitter / p95 error), tracking (MOTA / ID-switches / fragmentation), and vitals (breathing/heartbeat BPM error + SNR) into a `RuViewAcceptanceResult` with a `RuViewTier` (`Fail` / `Bronze` / `Silver` / `Gold`). ADR-145's `src/ablation.rs` extends this with presence accuracy, localization error, FP/FN, latency p50/p95/p99, a privacy-leakage score ∈ `[0,1]`, and cross-room degradation, under a determinism binding inherited from the ADR-011 proof harness.
+
+2. **A determinism substrate.** `proof.rs` (`PROOF_SEED=42`) SHA-256-hashes model outputs against an expected hash, so a scored run is reproducible and tamper-evident.
+
+What is missing is a **public, multi-entrant ranking**. As surveyed in ADR-015 and `docs/research/sota-surveys/sota-wifi-sensing-2025.md`, the WiFi-sensing field has **no hosted live leaderboard** the way vision has COCO/EvalAI — researchers self-report numbers against public *datasets* (MM-Fi, Wi-Pose, Person-in-WiFi, Widar3.0) in papers, with inconsistent splits, metrics, and no privacy or latency accounting. RuView's own pose number (PCK@20 ≈ 2.5% with proxy labels, target 35%+ per ADR-079) is currently self-reported on a private validation set and is not comparable to the MM-Fi SOTA (MultiFormer 0.7225).
+
+### 1.2 The Opportunity
+
+The harness that already gates RuView releases is exactly the engine a community leaderboard needs: a single, deterministic, privacy- and latency-aware scoring function. Publishing it as an open leaderboard:
+
+- Establishes **AetherArena as the field's standard yardstick** for spatial intelligence, with RuView's `RuViewTier` + ADR-145 metric set contributed as its initial basis (pose + tracking + vitals + **privacy-leakage** + latency + determinism — a combination no existing benchmark scores). The standard is AA's; RuView donates the seed.
+- Draws **any project, framework, or modality** to submit and rank — a cross-project community flywheel, not a RuView-only one (RuView's `wifi-densepose-pretrained` is merely the first baseline).
+- Forces the harness to harden: a public, neutral scorer must be reproducible by strangers, resistant to gaming, and runnable on a fixed held-out split nobody can train on.
+
+### 1.3 Constraints & Risks Up Front
+
+- **Leakage of the held-out split** is the existential risk for any leaderboard. The eval data must be private; submitters provide a model, not predictions on data they hold.
+- **Compute cost.** Scoring a submission runs inference over the eval set; an HF Space on free CPU may be too slow for the Candle/`tch` pipeline. Tiering of compute (CPU smoke vs GPU full score) is required.
+- **Privacy / consent of the eval data.** MM-Fi and Wi-Pose carry their own licenses; we can host *derived* CSI features and scores but must respect redistribution terms (ADR-015 already tracks this).
+- **Trust.** A `RuViewTier` badge is only meaningful if the scoring is deterministic and the leaderboard cannot be silently edited — the ADR-011 proof hash and a signed results ledger address this.
+
+---
+
+## 2. Decision
+
+**Create AetherArena ("AA") — the official, project-agnostic Spatial-Intelligence Benchmark: a public, open-entry leaderboard for camera-free spatial perception (pose, presence, occupancy, tracking, vitals) as a standalone repo `ruvnet/aether-arena` paired with a Hugging Face Space. The scoring engine is seeded by RuView's existing `ruview_metrics` + ADR-145 ablation harness, contributed as a neutral scorer; v0 evaluates against a private MM-Fi held-out split.**
+
+AA is **not a RuView leaderboard**. It is the field's missing standard yardstick for spatial intelligence — open to any team, framework, or sensing modality. The RF medium is the v0 input and RuView donates the seed harness + a baseline entry, but the benchmark is independent and RuView is scored like every other entrant. The metric surface — pose, presence, tracking, occupancy/world-model, latency, determinism, and later privacy — is modality-agnostic, leaving room to grow to mmWave / UWB / radar / lidar / multimodal entrants and other projects.
+
+The leaderboard does **not** fork or re-implement the scoring logic. It is a thin orchestration + presentation layer over the published `wifi-densepose-cli` scorer, so the public number a model earns is identical to the number RuView uses internally to gate releases. **This makes the leaderboard governance, not marketing.**
+
+The whole design reduces to a precise four-part structure:
+
+> **Public leaderboard. Private evaluation split. Open scorer. Signed results.**
+
+- **Public leaderboard** — anyone can see the ranking and submit.
+- **Private evaluation split** — the held-out data is never published; it cannot be trained on or overfit.
+- **Open scorer** — the scoring code is the published `wifi-densepose-cli`; a stranger can rerun it locally on a public *smoke* split and reproduce the logic.
+- **Signed results** — every score is an append-only, signed ledger row with a determinism proof hash; ranks cannot be silently edited.
+
+### 2.1 Name — DECIDED: `ruvnet/aether-arena` ("AA")
+
+**Locked.** Canonical repo + HF Space: **`ruvnet/aether-arena`**, branded **AetherArena** with the short form **"AA"**.
+
+- **"Aether"** = the classical all-pervading medium — fitting for RF/ambient spatial perception, and broader than "Ether"/CSI/WiFi so the benchmark can grow to mmWave, UWB, and multimodal spatial-intelligence entrants without a rename.
+- **"Arena"** = open competitive entry.
+- HF Space title: *AetherArena (AA) — the spatial-intelligence benchmark for RF perception.*
+- `ruvnet/wifi-densepose-leaderboard` is kept only as a discoverability/topic alias that redirects to AA.
+
+(Rejected: `csi-arena` — jargon; `rf-bench` — generic/collision; `wifi-densepose-leaderboard` as the primary — ties the brand to one capability.)

+                           one signed row per submission)
+```
+
+1. **Submission contract.** A submitter pushes a model artifact (`model.safetensors` / `.rvf` / LoRA adapter) plus a `ruview-arena.toml` manifest declaring: input feature set (which ADR-145 `FeatureSet` it consumes — F0 CSI / F1 CIR / F2 Doppler / F3 BFLD), tensor I/O contract, license, and optional category (pose / presence / tracking / vitals / multi-task).
+2. **Scoring.** The Space runs the **published `wifi-densepose-cli`** in a pinned container against a **private held-out split** of MM-Fi / Wi-Pose (and RuView's own paired-capture set per ADR-079). Output is the existing `RuViewAcceptanceResult` + the ADR-145 scalar set, plus the ADR-011 SHA-256 reproducibility hash.
+3. **Ledger.** Each scored submission appends **one signed row** to an append-only HF dataset (`ruvnet/aether-arena-results`, Parquet): `{submitter, model_ref, category, feature_set, tier, pck20, oks, mota, vitals_bpm_err, latency_p50, latency_p95, privacy_leakage, cross_room_deg, proof_sha256, scored_at, harness_version}`. Append-only + signed = no silent edits.
+4. **Presentation.** Gradio leaderboard with category tabs (Pose / Presence / Tracking / Vitals / Edge-latency / **Privacy**), `RuViewTier` badges, and a "privacy-respecting" filter (leakage ≤ threshold) — the differentiator no other WiFi benchmark has.
+
+### 2.2.1 Submission Lifecycle (quarantine before scoring)
+
+A submission is an untrusted artifact, so it moves through an explicit state machine — artifacts are isolated and validated **before** any scoring touches the private split. This is both the abuse-handling boundary and the UI flow:
+
+| State | Meaning |
+|-------|---------|
+| `submitted` | manifest received, job queued |
+| `validated` | schema, license, and artifact type accepted |
+| `quarantined` | artifact scanned; loaded into the sandbox (network disabled, read-only FS, runtime prepared) |
+| `smoke_scored` | passes the **public** smoke split (cheap CPU correctness check) |
+| `full_scored` | **private** held-out split score produced |
+| `published` | signed row appended to the ledger; appears on the board |
+| `rejected` | failed a gate — terminal, with a machine-readable reason |
+
+Only `quarantined` → `smoke_scored` → `full_scored` ever runs the model, always inside the sandbox of §2.4. A failure at any gate transitions to `rejected` with a reason rather than silently dropping.
+
+### 2.3 Categories & Metrics (reuse, do not invent)
+
+| Category | Primary metric (existing) | Source |
+|----------|---------------------------|--------|
+| Pose | PCK@20, OKS | `ruview_metrics::evaluate_joint_error` |
+| Tracking | MOTA, ID-switches | `ruview_metrics::evaluate_tracking` |
+| Vitals | breathing/HR BPM error, SNR | `ruview_metrics::evaluate_vital_signs` |
+| Presence | accuracy, FP/FN | ADR-145 `ablation.rs` |
+| Edge latency | p50 / p95 / p99 ms | ADR-145 `LatencyProfile` |
+| **Privacy** | leakage score ∈ `[0,1]` (membership-inference) | ADR-145 §10 |
+| Cross-room | degradation ratio | ADR-027 / ADR-145 |
+| Overall | `RuViewTier` Bronze/Silver/Gold + `arena_score` (§2.5) | `determine_tier()` |
+
+### 2.3.1 Phased Launch — v0 ships narrow
+
+**A narrow leaderboard that works beats a broad one with half-real metrics.** v0 ranks only categories whose metric is fully implemented and reproducible-by-strangers today; the rest are visible as **"coming soon" / gated** and are **not ranked** until their metric is real.
+
+| Category | v0 status | Gate to activate |
+|----------|-----------|------------------|
+| Presence | **Ranked** | — (implemented) |
+| Pose (PCK@20 / OKS) | **Ranked** | — (implemented) |
+| Edge latency (p50/p95/p99) | **Ranked** | — (implemented) |
+| Determinism proof | **Ranked** (pass/fail gate) | — (ADR-011, implemented) |
+| Tracking (MOTA) | Optional in v0 | enough multi-person eval clips in the private split |
+| Vitals (BPM error) | Optional in v0 | paired vital-sign ground truth in the split |
+| **Privacy leakage** | **Coming soon — gated, not ranked** | ADR-145 §10 membership-inference attacker implemented + published |
+| Cross-room generalization | Coming soon | multi-room held-out split assembled (ADR-027) |
+
+**v0 launch language (explicit, to stay honest and non-contradictory):** *AetherArena v0 starts with pose, presence, edge latency, and deterministic reproducibility. Tracking and vitals are activated when sufficient ground-truth clips are available. Privacy-leakage and cross-room generalization remain gated until their evaluation attacks and splits are implemented and published.* Shipping a "privacy leaderboard" claim before the attacker exists would be an easy and deserved attack on our credibility.
+
+### 2.4 Threat Model
+
+The leaderboard is only credible if its failure modes cannot be hidden. Explicit threats and the control that neutralizes each:
+
+| Threat | Control |
+|--------|---------|
+| Model exfiltrates / phones home the eval data | Scorer container runs with **no network, read-only eval FS, resource caps** (sandboxed) |
+| Submitter overfits the public split | **Private held-out split** — never published; scoring runs on data the submitter has never seen |
+| Model fingerprints / detects the eval set | **Seasonal rotation** of a fraction of the held-out split (mirrors ADR-120 hash rotation) |
+| Maintainer silently edits a score / rank | **Witness chain**: append-only, hash-chained ledger (`ledger/ledger_tools.py`) — each row references the prior row's hash, so any edit breaks every subsequent link and `verify` fails |
+| A score can't be reproduced / hides nondeterminism | **Witness + repeatability analysis**: each score is a witness (`inputs_sha256` binding it to the exact inputs + `proof_sha256` of the quantised result + `harness_version`); `aa_score_runner --repeat N` runs the harness N× and fails if it ever produces ≥2 distinct proof hashes |
+| Scorer version drift changes ranks invisibly | **`harness_version` pinned per witness**; a scorer change moves the proof hash and fails the CI determinism gate until regenerated + reviewed |
+| Slow model brute-forces accuracy | **Latency is a ranked axis** (p50/p95/p99) with hard caps + the `latency_factor` in `arena_score` |
+| "Gold accuracy, leaks identity" win | **Privacy is a (gated) axis**; once active, `privacy_factor` penalizes leakage in `arena_score` |
+| Malicious model artifact (RCE in the scorer) | Untrusted artifact loaded in the sandboxed container only; pinned, minimal runtime; no host mounts |
+
+### 2.5 Overall Score (anti-"accuracy-at-any-cost")
+
+Categories are ranked independently (tabs), **and** an optional headline `arena_score` composes them so a model cannot win on raw accuracy while being slow, leaky, or non-reproducible:
+
+```
+arena_score = quality_score × latency_factor × privacy_factor × determinism_gate
+```
+
+| Component | Rule |
+|-----------|------|
+| `quality_score` | normalized blend of PCK@20 / OKS / MOTA / vitals for the category, ∈ `[0,1]` |
+| `latency_factor` | `1.0` if p95 ≤ target; decays smoothly above target (edge viability) |
+| `privacy_factor` | `1.0 − privacy_leakage` once the Privacy axis is active; **fixed at `1.0` in v0** (privacy gated/unranked) |
+| `determinism_gate` | `1.0` if the ADR-011 proof hash matches; **`0` if it fails** — a non-reproducible run cannot rank at all |
+
+The multiplicative form means any single hard failure (non-deterministic, or — later — high leakage) collapses the headline score, even at SOTA accuracy. In v0, `privacy_factor` is pinned to `1.0` so the headline number is honest about what is actually measured.
+
+**`arena_score` is a gate, not the only headline.** Multiplicative composites are great for gating but can hide *why* a model lost, and invite "your formula is biased" arguments. So the board ranks **category performance first** and exposes the composite alongside, never instead:
+
+| Surface | What it shows |
+|---------|---------------|
+| **Primary rank** | the category metric (e.g. PCK@20 for Pose) — this is the sort key per tab |
+| **Integrity badge** | determinism proof pass/fail |
+| **Edge badge** | p95 latency band |
+| **Overall score** | `arena_score` as an *optional* governance-weighted composite |
+
+> The leaderboard ranks category performance first, then exposes `arena_score` as a governance-weighted composite so accuracy, latency, reproducibility, and privacy are visible rather than collapsed into a single opaque number.
+
+### 2.6 Dataset Legality (investigated — resolved for v0)
+
+Confirmed against ADR-015 §dataset-licenses:
+
+| Dataset | License | What AA may do |
+|---------|---------|----------------|
+| **MM-Fi** | **CC BY-NC 4.0** | ✅ v0 eval source. Non-commercial use + derivatives **permitted with attribution**. AA may host *derived* CSI features and scores; raw frames stay in the private split. AA must be operated **non-commercially** and carry MM-Fi attribution. |
+| **Wi-Pose** | **"Research use"** (no clean redistribution grant) | ⚠️ **Not hosted.** Pulled privately into the scorer only, never redistributed; or deferred until terms are clarified with the authors. **Dropped from v0.** |
+| Person-in-WiFi-3D | semi-public access | Future candidate (post-v0), pending access terms. |
+
+**v0 decision:** evaluate on a **private MM-Fi held-out split only** (CC BY-NC, attributed, non-commercial; expose only license-permitted derived features). Wi-Pose is removed from v0 and revisited if/when redistribution is cleared. This keeps the existential "can we even host this" risk at zero for launch.
+
+> **Non-commercial caveat to watch:** CC BY-NC means AA itself, and the eval-data use, must remain non-commercial. Because AA also showcases the (commercial) RuView appliance, keep AA legally distinct and non-commercial, or seek an MM-Fi commercial grant before any paid tier. Flagged for the maintainer.
+
+### 2.7 Non-Gameability Is a Launch Gate
+
+Per the explicit directive, AA does not launch unless the harness is demonstrably hard to game. The controls (private split §2.4, seasonal rotation §2.4, model-not-prediction submission §2.2, sandbox §2.4, pinned `harness_version` §2.4, signed append-only ledger §2.3-§2.4, multiplicative `arena_score` §2.5, `determinism_gate=0` on proof-hash failure §2.5) are **not optional hardening — they are acceptance criteria** (see §7). A v0 that can be topped by overfitting a public split, a non-reproducible run, or a silently edited row is, by definition, not ready.
+
+### 2.8 Neutrality & Governance (because it's "official" and cross-project)
+
+The hardest credibility problem for an *official* benchmark seeded by one entrant: **"RuView built the scorer, so of course RuView wins."** If AA is to be the field's standard rather than RuView marketing, neutrality must be structural, not promised:
+
+| Neutrality risk | Control |
+|-----------------|---------|
+| RuView's entry gets special treatment | RuView is submitted through the **same** public pipeline (§2.2.1) and scored by the **same** pinned scorer as everyone else; its rows carry the same proof hash and are independently re-runnable on the smoke split. |
+| RuView tunes the metric to favor its models | The scorer is **open and versioned**; any metric change is a public `harness_version` bump that **re-scores all entries**, not just new ones. Metric changes go through a public changelog. |
+| "Official" is self-declared | AA is positioned as a **neutral commons**: separate repo/Space identity, contribution guide, and an explicit invitation for other projects + dataset authors to co-own splits and metrics. RuView is the *donor of the seed harness*, not the owner of the standard. |
+| Benchmark used as RuView ad | Keep AA legally + brand-distinct (ties into the CC BY-NC non-commercial caveat, §2.6); the README leads with the standard, not the product. |
+| Single-vendor capture | Roadmap to a multi-org steering/eval committee once ≥N external projects enter; split rotation + metric proposals are public. |
+
+The test for neutrality is the same as §7's acceptance test: a stranger from *another project* can submit, reproduce the score, and see that RuView's own entries were scored by the identical, open, pinned path.
+
+---
+
+## 3. Consequences
+
+### 3.1 Positive
+- A real, comparable public number for RuView (and everyone else) on MM-Fi / Wi-Pose, scored by a privacy- and latency-aware harness no other WiFi benchmark offers.
+- Community flywheel: external models/adapters get ranked, feeding `ruvnet/wifi-densepose-pretrained`.
+- Forces the harness to be reproducible-by-strangers, which strengthens internal release gating too.
+
+### 3.2 Negative / Costs
+- **New repo + HF Space to maintain**, incl. a scoring container and queue. Ongoing compute cost (mitigate: CPU smoke-score on submit, batched GPU full-score on a schedule).
+- **Dataset licensing** must be cleared for hosting derived MM-Fi / Wi-Pose features (ADR-015 owns this; may require contacting dataset authors).
+- **Abuse surface** (malicious model artifacts run in the scorer) — must sandbox the container (no network, read-only eval data, resource caps).
+
+### 3.3 Neutral
+- The scoring logic stays in `wifi-densepose-train`/`-cli`; the leaderboard is presentation only, so it does not bloat the core workspace.
+
+---
+
+## 4. Alternatives Considered
+
+1. **Submit RuView to existing venues only (MM-Fi GitHub, Papers-with-Code).** Lower effort, but no privacy/latency axes, no live entry, and RuView doesn't own the standard. *Complementary, not exclusive — we should still post MM-Fi numbers.*
+2. **A static numbers page in the RuView README.** Zero infra, but not multi-entrant and not a leaderboard.
+3. **EvalAI / Kaggle competition.** Stronger anti-gaming infra, but heavyweight, time-boxed, and off-brand vs an always-open HF Space next to the model.
+
+---
+
+## 5. Open Questions
+
+1. **Eval data hosting** — can we redistribute derived MM-Fi / Wi-Pose CSI features under their licenses, or must scoring pull the raw datasets the submitter cannot see? (Owner: ADR-015 follow-up.)
+2. **Compute budget** — free HF CPU Space, ZeroGPU, or a self-hosted scorer on the GCloud A100/L4 fleet (`cognitum-20260110`)?
+3. **Name lock** — confirm `aether-arena` vs `wifi-densepose-leaderboard`.
+4. **Season cadence** — does the held-out split rotate monthly, and do we keep an all-time + per-season board?
+5. **Privacy-leakage attack** — ship the membership-inference attacker (ADR-145 §10 is currently a *defined-but-unimplemented* metric) before launch, or launch with privacy as a "coming soon" axis?
+
+---
+
+## 6. Implementation Sketch (if accepted)
+
+- **P1** — Stand up `ruvnet/aether-arena` repo + skeleton Gradio HF Space; define `ruview-arena.toml` submission contract; publish a **public smoke split** a stranger can score locally.
+- **P2** — Containerize `wifi-densepose-cli score` as the pinned, sandboxed scorer (no network, read-only FS, caps); wire the signed append-only Parquet ledger + `determinism_gate`.
+- **P3 — v0 LAUNCH (narrow).** Clear + load the private MM-Fi / Wi-Pose held-out split; activate **Presence, Pose, Edge-latency, Determinism** categories; seed the board with RuView's own `wifi-densepose-pretrained` baseline (honest current PCK@20). Tracking/Vitals optional. Privacy + Cross-room shown as **gated / coming soon**.
+- **P4** — *(post-launch, gated)* Implement the ADR-145 §10 privacy-leakage membership-inference attacker; only then activate + rank the **Privacy** category and switch `privacy_factor` on in `arena_score`.
+- **P5** — Assemble the multi-room split → activate **Cross-room**. Submit RuView's MM-Fi number to Papers-with-Code in parallel (alternative #1).
+
+## 7. Acceptance Test (definition of done for v0)
+
+v0 launches **only when a stranger can:**
+
+1. **Submit** a model (artifact + `ruview-arena.toml`) through the Space with no insider help,
+2. **Get a deterministic score** back (same model + same harness version → same numbers),
+3. **See the signed row** appended to the public results ledger,
+4. **Rerun the scorer locally** on the public *smoke* split and reproduce the logic, and
+5. **Understand why the rank is fair** — private split, open scorer, pinned version, proof hash — from the docs alone.
+
+If any of these five fails, v0 is not ready.
+
+## 8. Suggested Announcement (draft)
+
+> **I'm proposing AetherArena** — a public leaderboard for WiFi sensing, RF perception, and ambient intelligence.
+>
+> The problem with this field is not just model quality. It is *measurement* quality. Most WiFi-sensing work reports numbers against datasets with inconsistent splits, inconsistent metrics, and almost no accounting for latency, privacy leakage, reproducibility, or edge viability.
+>
+> AetherArena fixes that. Models are submitted, scored in a pinned sandboxed container against **private** held-out MM-Fi and Wi-Pose splits, and written to a **signed append-only** results ledger. The scoring engine reuses the same RuView harness we use internally: pose, presence, tracking, vitals, latency, cross-room degradation, deterministic proof hashes — and, once its attacker ships, privacy leakage.
+>
+> The goal is not to make RuView look good. The goal is to make the *category* measurable. If ambient intelligence is going to move from demos to infrastructure, it needs public numbers, reproducible commands, private eval splits, and failure modes that cannot be hidden.

+> plus a `SotaComparison` against Wi2SAR. This ADR defines **how we evaluate the swarm
+> rigorously** — what metrics, what statistics, what baselines, and an honest account
+> of which external leaderboards do and do not apply.
+
+---
+
+## 1. Context
+
+ADR-148's `ruview-swarm` reports performance via five `criterion` micro-benchmarks and a
+single `SotaComparison` (localization 1.732 m vs Wi2SAR 5 m; coverage ~223 s vs 810 s).
+These numbers are **internally valid but insufficient as scientific claims**:
+
+- The criterion figures (3.3 µs MARL inference, 43 µs RRT-APF, 54 ns fusion, 248 µs PPO
+  step) measure **wall-clock latency**, not policy quality or coverage/localization quality.
+- The 1.732 m localization comes from a **single synthetic geometry** (3 drones at 120°
+  around a known point), not a distribution of victim positions under realistic noise.
+- The 223 s coverage is an **analytic estimate** (`estimate_coverage_time_secs()`), not an
+  episode rollout.
+- All numbers are **single-run point estimates**. The MARL reproducibility literature
+  (Henderson 2018; Agarwal 2021; Gorsane 2022) shows single/few-seed point estimates
+  routinely flip algorithm rankings and overstate gains.
+
+We need a defined, reproducible evaluation methodology before any "beats SOTA" claim can
+survive external review, and an honest position on external leaderboards.
+
+---
+
+## 2. Decision
+
+Adopt a two-tier evaluation methodology:
+
+1. **Micro-benchmarks (criterion)** — keep for compute-latency regression gating only.
+   Explicitly labeled as latency, never as quality.
+2. **Domain evaluation harness** — a seeded, multi-run, statistically-reported harness
+   producing SAR metrics (localization CEP, coverage, detection rate) and MARL metrics
+   (IQM return, probability-of-improvement) over **≥10 seeds with 95% stratified-bootstrap
+   confidence intervals**, against **≥3 baselines**, following the Agarwal/Gorsane standard.
+
+Do **not** claim leaderboard standing — no public leaderboard accepts drone-swarm CSI-SAR
+submissions. Comparisons to Wi2SAR are **paper-to-paper**, labeled as such, acknowledging
+the sensing-modality difference (RSS bearing vs CSI multi-view fusion).
+
+---
+
+## 3. External Leaderboard Landscape — Honest Assessment
+
+**There is no public, externally-administered leaderboard that accepts a drone-swarm,
+CSI-based, multi-view SAR system.** This is a research niche; comparison is paper-to-paper.
+The adjacent options and their fit:
+
+| Benchmark / Leaderboard | Domain | Live submission? | Fit for ruview-swarm |
+|-------------------------|--------|------------------|----------------------|
+| **Wi2SAR** (arxiv 2604.09115) | Drone WiFi SAR | No (paper) | **Direct baseline** — paper-to-paper only; RSS bearing ≠ CSI fusion |
+| **MARL4DRP** (Springer 2023) | Drone routing MARL | No | Closest drone-MARL benchmark; would need a routing→coverage adapter |
+| **CSI-Bench** (NeurIPS 2025) | Static WiFi sensing | Splits + paper baselines | Adjacent (localization task) but no moving-sensor/multi-view fusion |
+| **SMAC / SMACv2** | StarCraft cooperative MARL | No live LB | Structural analogy (CTDE) only; combat task, not coverage |
+| **PettingZoo MPE** (Simple Spread) | 2D cooperative particles | No | Cheap MARL **correctness check**, no physics/CSI |
+| **Melting Pot** | Social-dynamics MARL | Closed (NeurIPS '24) | Not applicable |
+| **MAMuJoCo / Hanabi / GRF / Overcooked** | Various cooperative MARL | No live LB | Not applicable |
+| **OmniDrones / gym-pybullet-drones / Pegasus** | Drone-control sim platforms | No (platforms) | **Training infrastructure**, not leaderboards; no CSI layer |
+
+**Conclusion:** We will (a) keep Wi2SAR as the cited paper baseline, (b) optionally build a
+MARL4DRP/MPE adapter to post a recognized cooperative-MARL number (tangential to SAR), and
+(c) **not** represent any internal number as a leaderboard placement.
+
+---
+
+## 4. Evaluation Metrics
+
+### 4.1 SAR Domain Metrics (primary — comparable to Wi2SAR)
+
+| Metric | Definition | Reporting |
+|--------|-----------|-----------|
+| Localization CEP50 | Median horizontal error, fused victim position vs ground truth | m, 95% CI |
+| Localization CEP95 | 95th-percentile horizontal error | m |
+| **GDOP** | Geometric Dilution of Precision of the contributing-drone constellation at detection time | dimensionless (tracked per detection) |
+| Coverage rate @ T | Fraction of area scanned ≥1× within T=240 s | %, 95% CI |
+| Coverage time to 95% | Time to scan 95% of bounded area | s, mean ± CI |
+| Time-to-first-detection | Mission start → first confident detection (conf > 0.85) | s, 95% CI |
+| Detection rate | P(detected \| victim present) per mission | %, 95% CI |
+| False-alarm rate | P(confident detection \| no victim) | %, 95% CI |
+| Collision rate | Collisions (d < 1.5 m) per mission | count/mission |
+| Overlap ratio | Fraction of path re-covering scanned cells | % |
+
+### 4.2 MARL Policy-Quality Metrics
+
+| Metric | Definition |
+|--------|-----------|
+| IQM episodic return | Interquartile mean over 10 seeds × 50 eval episodes (Agarwal 2021) |
+| Probability of improvement | P(MAPPO return > IPPO return) on a random episode |
+| Optimality gap | Expected gap to a defined reference performance |
+| Performance profile | Fraction of (seed, episode) with localization error < τ, plotted vs τ ∈ [0,10] m |
+| Sample efficiency | Return vs training steps (curve, not point) |
+
+### 4.3 Micro-benchmarks (criterion — latency only)
+
+Retained from ADR-148, **labeled as compute latency, not quality**:
+`marl_actor_inference` 3.3 µs · `rrt_apf_100iter` 43 µs · `multiview_fusion_3drones` 54 ns ·
+`demo_coverage_estimate` 100 ps · `ppo_update_64transitions` 248 µs. Purpose: prove the
+control loop has no compute bottleneck (all ≪ the 10 ms / 100 Hz budget) and gate
+performance regressions. They are **not** evidence of policy or localization quality.
+
+---
+
+## 5. Statistical Protocol (Agarwal 2021 / Gorsane 2022)
+
+| Requirement | Standard adopted |
+|-------------|------------------|
+| Seeds per condition | **≥10** training runs from distinct seeds |
+| Evaluation episodes | 50 fixed, versioned episodes per trained policy (10 victim layouts × 5 CSI-noise levels) |
+| Aggregate metric | **IQM** (not mean, not median) + performance profiles |
+| Confidence intervals | **95% stratified bootstrap**, 1,000 resamples |
+| Baselines (≥3) | Random walk (lower bound), Boustrophedon+manual-triangulation (heuristic), IPPO (no shared critic) |
+| Reproducibility | Versioned YAML config (drone count, area, victims, CSI σ amplitude / κ phase, wind, packet loss) + all seeds committed with results |
+
+Rationale: Henderson et al. (2018) found ≤5-seed point estimates flip rankings; Agarwal et
+al. (2021, NeurIPS Outstanding Paper) show IQM needs ~10 runs for the statistical power that
+the median needs ~200 runs for; Gorsane et al. (2022) made ≥10 seeds + IQM + stratified CIs
+the cooperative-MARL standard. `rliable` (google-research/rliable) is the reference impl.
+
+---
+
+## 6. Reproducibility Harness (`evals/`)
+
+A new evaluation harness (separate from criterion micro-benchmarks):
+
+1. **Seeded episodes** — every episode, noise perturbation, and training run seeded from a
+   versioned config; seeds committed with results (no `Date.now()`/unseeded RNG).
+2. **Per-episode logging** — coverage %, localization error, GDOP, time-to-first-detection,
+   collisions, detection binary → JSONL (reuses the ADR-148 telemetry schema).
+3. **Aggregation** — IQM ± 95% stratified-bootstrap CI across the 10-seed × 50-episode matrix.
+4. **Baseline sweep** — random / boustrophedon-heuristic / IPPO / MAPPO, so
+   probability-of-improvement and performance profiles are computable.
+5. **Output** — committed `evals/RESULTS.md`: a reproducible internal leaderboard ranking
+   our 6 flight patterns × learning patterns on the SAR metrics, plus the Wi2SAR paper row.
+
+This `RESULTS.md` is the **real, defensible "leaderboard" for this system** — patterns ranked
+against each other and the cited baseline, reproducibly, with CIs.
+
+### 6.1 Dual-stage pipeline (compute-cost mitigation)
+
+The full matrix is **10 seeds × 50 episodes × ≥4 conditions = ≥2,000 rollouts per policy**.
+Running each rollout against the OccWorld 3D prior (ADR-147, ~375 ms/inference) would melt
+the L4 / RTX 5080 budget. Split evaluation into two stages:
+
+- **Stage 1 — Kinematic (fast, full matrix).** Stripped vector environment; OccWorld paths
+  pre-cached or treated as static analytical volumes. Produces episodic **return, IQM,
+  sample-efficiency curves, coverage %, GDOP, localization error** over the full 10-seed matrix.
+- **Stage 2 — High-fidelity physics (sub-sampled).** Take the **3 median seeds** (by Stage-1
+  IQM) into Gazebo + PX4 SITL with full CSI phase/amplitude noise. Extracts **false-alarm
+  rate** and **collision rate** under realistic dynamics (heading-rate limits, APF repulsion,
+  motor response) that the kinematic sim omits.
+
+Stage 1 is CI-runnable today; Stage 2 requires the Gazebo/PX4 SITL bring-up (follow-on).
+
+### 6.2 Noise sweep (coherence-gate threshold)
+
+The config generator systematically varies the two CSI noise parameters:
+- **σ** — Gaussian amplitude noise (CSI magnitude)
+- **κ** — von Mises phase concentration (lower κ = noisier phase)
+
+Sweeping (σ, κ) isolates the exact environmental threshold where `CrossViewpointAttention`
+(ADR-016) drops out of its coherence gate (`coherence_gate.rs` Accept → PredictOnly/Reject,
+ADR-135). This finds the operating envelope, not just a single-point accuracy.
+
+### 6.3 GDOP tracking
+
+Localization accuracy is meaningless without the constellation geometry that produced it.
+The harness records **GDOP** per detection: 3 drones in a ~120° constellation give the
+√3 ≈ 1.73× CRLB improvement; 3 **collinear** drones degrade toward the single-view
+Cramer-Rao limit (~2.9 m). Reporting localization error **stratified by GDOP band** prevents
+the headline number from being a best-case geometric artifact.
+
+---
+
+## 7. Evidence Grading of Current ADR-148 Numbers
+
+| Claim | Grade | Why |
+|-------|-------|-----|
+| criterion latencies (3.3 µs / 43 µs / 54 ns / 248 µs) | **High** | Deterministic compute, hardware-specific, reproducible |
+| Wi2SAR baseline (5 m, 160k m²/13.5 min) | **High** | Published field trial, open source |
+| 1.732 m 3-view localization | **Low–Medium** | Single synthetic geometry; no noise distribution; CRLB predicts ~2.9 m for N=3 |
+| 223 s 4-drone coverage | **Low** | Analytic estimate, not an episode rollout |
+| "beats SOTA" | **Directional only** | Valid as paper-to-paper direction; not leaderboard, not multi-seed |
+
+The √N multi-view scaling claim is theoretically sound (CRLB: σ ∝ 1/√(N·SNR); N=3 → √3 ≈
+1.73× improvement), but the measured 1.732 m must be reproduced over a victim-position and
+noise distribution before it is defensible.
+
+---
+
+## 8. Consequences
+
+### Positive
+- Converts scattered numbers into a reproducible, statistically-honest evaluation.
+- The `RESULTS.md` internal leaderboard ranks the 6 flight × 4 learning patterns fairly.
+- Aligns with the recognized MARL evaluation standard (IQM + stratified CIs + ≥10 seeds).
+- Honest external-leaderboard position avoids overclaiming.
+
+### Costs / Risks
+- ≥10 seeds × 50 episodes × N patterns × N baselines is a real compute cost — this is where
+  the ADR-148 GCP L4 / local RTX 5080 training budget is actually spent.
+- Requires the MARL policy to be **trained to convergence** first (the ADR-148 5-episode CPU
+  run shows decreasing value_loss, not convergence).
+- Coverage/localization must move from analytic estimate / synthetic geometry to **episode
+  rollouts under realistic CSI noise** before headline numbers are republished.
+
+### Open issues → follow-on work
+1. Train MAPPO/IPPO to convergence (M4 follow-on) before running the eval harness.
+2. Build the seeded `evals/` harness + `RESULTS.md` generator.
+3. Optional: MARL4DRP or MPE Simple-Spread adapter for a recognized cooperative-MARL number.
+4. Re-state ADR-148 §14 headline numbers with CIs once the harness has run.

+## 1. Context
+
+AetherArena now has a published, metric- and protocol-matched MM-Fi result: **81.63% torso-PCK@20 in-domain (random_split), exceeding MultiFormer's 72.25%** ([#876](https://github.com/ruvnet/RuView/issues/876)). But the **leakage-free cross-subject** number collapses to **~11.6% torso-PCK** (27% under the looser bbox metric). That gap is the real deployment frontier — homes, elder care, festivals, unseen bodies.
+
+Naïve fixes already tested and **failed**: a subject-adversarial (DANN) embedding did not move cross-subject (baseline 27.26% → DANN 27.54% bbox; torso 11.57%). Bigger capacity *hurt* (transformer cross-subject 24.8% < conv 27.3%) — extra parameters overfit seen subjects.
+
+**Conclusion:** a *generic* "better feature vector" will not help. The lever is an embedding trained for the **right invariance** — one that preserves pose while removing subject, room, and device signatures, and that *exposes* channel instability rather than hiding it.
+
+### 1.1 Why DANN failed (and the corrected rule)
+
+Subject identity is partly **entangled with valid pose evidence** — body scale, limb proportions, gait, RF scattering. Blindly erasing subject info also erases information the pose decoder needs. The corrected rule:
+
+> **Remove subject identity only after preserving pose geometry.** Supervised *pose-contrast across subjects* beats naïve adversarial identity removal.
+
+The frontier objective is **not** `same-subject = positive`. It is:
+
+> **same pose across different subjects = positive; different pose = negative.**
+
+## 2. Decision
+
+**Build the RuView RF Foundation Encoder: a self-supervised, pose-preserving, subject/room/device-invariant RF representation for CSI (extensible to CIR, ADR-134, and BFLD).** Positioned as a **platform primitive**, not a benchmark trick.
+
+### 2.1 What the embedding must keep / remove
+
+| Signal | Action | Why |
+|--------|--------|-----|
+| Pose geometry | **Keep** | target signal |
+| Limb-motion deltas | **Keep** | strong temporal cue |
+| Subject identity | **Remove** (post-pose) | causes overfit |
+| Static room multipath | **Remove** | breaks transfer |
+| Device-specific phase artifacts | **Remove** | breaks cross-hardware |
+| Antenna-layout quirks | **Normalize** | deployment portability |
+| Channel instability | **Expose separately** | confidence gating / anti-hallucination |
+
+### 2.2 Architecture
+
+```
+CSI frame sequence
+  → physics normalization        (antenna geometry, subcarrier stability, phase-unwrap quality, room-impulse structure)
+  → masked CSI encoder           (SSL: learn channel structure from unlabeled CSI — 150k home + 320k MM-Fi frames)
+  → temporal contrastive encoder (motion continuity)
+  → skeleton-aware pose decoder  (graph head — anatomical constraints, GraphPose-Fi style, arXiv 2511.19105)
+  → confidence + coherence head  (mincut / spectral coherence as RF-integrity signal)
+```
+
+### 2.3 Training objectives (loss stack)
+
+```
+L_total = L_pose
+        + 0.20 · L_masked_csi          # learn channel structure (unlabeled)
+        + 0.10 · L_temporal_contrast   # motion continuity
+        + 0.20 · L_pose_contrast        # same-pose-across-subjects = positive  ← the frontier
+        + 0.05 · L_subject_decorrelation # remove identity only where it conflicts with pose
+        + 0.10 · L_coherence            # predict when RF evidence is weak
+```
+
+Invariant target:
+```
+embedding ≈ pose + motion + channel-coherence
+embedding ≠ subject-identity + static-room-signature + device-artifact
+```
+
+### 2.4 The RuView differentiator — auditable RF perception that knows when it's wrong
+
+The coherence head gates pose confidence by **channel coherence**: when multipath structure changes (mincut / spectral coherence drop), the model flags low RF integrity instead of hallucinating a pose. This is the **anti-hallucination** component most WiFi-pose papers lack, and it turns RuView from a model into sensing infrastructure. (Ties to ADR-135 coherence gate.)
+
+## 3. Experiment plan — three variants, frozen-decoder test
+
+Same split, same decoder, same seed set; only the embedding changes.
+
+| Variant | Description | Success threshold (cross-subject torso-PCK) |
+|---------|-------------|----------------------------------------------|
+| **E1** | Masked CSI pretrain | **+3** |
+| **E2** | Pose-contrastive across subjects | **+6** |
+| **E3** | Physics-normalized SSL + skeleton head | **+10** |
+
+### 3.1 Expected gains (estimate)
+
+| Method | cross-subject torso-PCK gain |
+|--------|------------------------------|
+| Naïve embedding | 0–2 |
+| DANN adversarial | 0–3 (high collapse risk) — *empirically ~0* |
+| Masked CSI pretrain | +3–8 |
+| Pose-contrastive | +5–12 |
+| Physics-norm + SSL + graph decoder | +10–20 |
+| + more subject-diverse paired data | +20 |
+
+Plausible trajectory: 11.6% → **20–25% near term**, **30–40% with enough subject/environment diversity**. That is a stronger research claim than squeezing random-split from 81.6% → 88%.
+
+### 3.2 Empirical findings (2026-05-31) — measured, not estimated
+
+The near-term algorithmic estimates in §3.1 were **tested directly on the official MM-Fi
+cross-subject split** (256,608 train / 64,152 test, same TF pipeline). Measured results:
+
+| Method | §3.1 estimate | **Measured** | Verdict |
+|--------|--------------:|-------------:|---------|
+| Baseline (in-harness) | — | 63.13% (doc TTA 64.04) | reference |
+| Mixup | n/a | **+0.7** → 63.79% | ✅ small |
+| Mixup + TTA + 3-seed ensemble | n/a | **+0.9** → **64.92%** | ✅ **best** |
+| Per-antenna instance-norm + SpecAugment | n/a | **−4.6** → 58.52% | ❌ destroys cross-antenna pose structure |
+| **Pose-contrastive foundation pretrain** | **+5 to +12** | **−2.3** → 62.65% | ❌ **refuted** |
+| DANN adversarial | ~0 | ~0 | ❌ (as predicted) |
+
+**Why pose-contrastive pretraining fails — the key finding.** The supervised-contrastive
+pretraining loss (positives = same pose-cluster, spanning subjects) **never left the
+uniform-similarity floor `ln(B)`** — across cluster granularities K∈{48,256}, batch sizes
+{768,1024}, and 3 seeds. The same encoder trivially aligns *temporally-adjacent* frames
+(temporal-triplet SSL reached 82%), so the optimizer works; it simply **cannot pull same-pose
+CSI from different subjects together — that invariance is not present in the data to be learned.**
+
+**Implication for this ADR.** The 18-pt in-domain↔cross-subject gap (83.6% → best 64.9%) is
+**fundamental subject-distribution shift in CSI, not an algorithmic gap.** No invariance-learning
+method tested moves it; only variance-reduction (mixup + ensemble) gives <1 pt. This **promotes
+"more subject-diverse paired data" (§3.1 last row, §6 alt 3) from complementary to the *primary*
+lever** and **demotes pure-SSL-on-existing-data** as a near-term cross-subject win. The encoder is
+still worth building for masked-CSI representation reuse and the coherence integrity head, but the
+cross-subject acceptance gate (§4, ≥6 pts) is **unlikely to be met without new multi-subject
+capture** (fleet: `cognitum-seed-1` + multi-room, see `CLAUDE.local.md`). Recommend re-scoping
+phase 1 around data collection before further loss-stack engineering.
+
+### 3.3 Subject-scaling study (2026-05-31) — capture *diversity*, not *volume*
+
+Before committing to capture, we measured **how cross-subject accuracy scales with the number of
+training subjects** (fixed held-out test subjects, official split, mixup+TTA):
+
+| N subjects | 4 | 8 | 12 | 16 | 20 | 24 | 32 |
+|-----------:|--:|--:|---:|---:|---:|---:|---:|
+| xsubj-PCK@20 | 36.7 | 57.7 | 58.3 | 61.1 | 62.7 | 63.3 | **63.7** |
+
+The curve **saturates**: 4→8 subjects = **+21 pts**, but 24→32 = **+0.45 pts**. Asymptote ≈ 64–65%,
+still ~19 pts under in-domain. **Key correction to the "more data" recommendation:** simply capturing
+*more people from the same distribution* will **not** close the gap — subject-count returns vanish
+past ~16–20 subjects. The residual is **device/room/protocol shift** (MM-Fi's cross-subject split is
+partly cross-environment by construction). **Re-scoped phase-1 capture target: maximize DIVERSITY
+(rooms, devices, antenna geometries, traffic protocols), not headcount** — and pair it with few-shot
+target-domain adaptation (a handful of labeled frames from the deployment room), which the saturation
+curve implies will beat any amount of additional source subjects. This makes the encoder's
+*domain-invariance* objective (vs the failed subject-invariance one) the design priority.
+
+### 3.4 Few-shot target adaptation (2026-05-31) — the actionable resolution
+
+The saturation curve predicts a few labeled frames from the *deployment* room beat more source
+subjects. Confirmed. Base trained on all 32 source subjects (63.7% zero-shot on a disjoint 50%
+held-out of the target subjects), then fine-tuned on K labeled frames per target subject:
+
+| K/subject | total frames | eval PCK@20 | Δ |
+|----------:|-------------:|------------:|--:|
+| 0 | 0 | 63.7% | — |
+| 20 | 160 | 68.1% | +4.3 |
+| **50** | **400** | **72.2%** | **+8.5 (≈ prior SOTA)** |
+| 200 | 1,600 | 76.1% | +12.4 |
+| 1000 | 8,000 | 78.3% | +14.6 |
+
+**Few-shot calibration dominates source volume.** §3.3 showed +24 source subjects (~190K frames)
+buys +6 pts; here **200 target frames/subject (1,600 frames) buys +12.4 pts**. This **re-scopes the
+ADR's acceptance gate and deployment story**: the cross-subject gate (§4, ≥6 pts) is *trivially* met
+by ~50–200 labeled frames of in-room calibration — no foundation encoder or mass capture required for
+the deployment win. **Recommended product behavior:** ship a **~30-second on-site calibration** (a few
+hundred labeled frames per room/person) that recovers most of the gap. The foundation encoder's value
+shifts from "close cross-subject zero-shot" (data says: hard) to "make the few-shot adaptation faster /
+need fewer calibration frames" — a better-posed, achievable objective. **This supersedes the §3.2
+pessimism: the frontier is not closed by algorithms or bulk data, but it *is* cheaply closed at
+deployment time by few-shot calibration.**
+
+> **Task-general (2026-05-31).** The same mechanism was verified on a *second* MM-Fi task —
+> 27-class **action recognition** (which the MM-Fi paper never benchmarked for WiFi). Zero-shot
+> cross-subject collapses to ~10% (near-chance), and few-shot calibration recovers it: 50 samples →
+> 36%, 200 → 59%, 1000 → 76%. Action needs more calibration than pose (classification vs regression),
+> but the pattern is identical. **Few-shot in-room calibration is the universal deployment answer for
+> WiFi sensing generalization, not a pose-specific result.** (Optimization report §36.)
+
+### 3.5 Deployable adapter calibration (2026-05-31) — the calibration-service mechanism
+
+Full-finetune calibration (§3.4) means a 2.3 MB model copy per room. Compared calibration methods at
+K=200 frames/subject by accuracy *and* adapter size:
+
+| Method | PCK@20 | trainable | adapter |
+|--------|-------:|----------:|--------:|
+| zero-shot | 63.6% | — | — |
+| **LoRA rank-8** | **72.5%** | 11,200 | **~11 KB** |
+| head+graph only | 72.7% | 121,828 | 119 KB |
+| frozen-trunk | 73.5% | 212,453 | 207 KB |
+| full finetune | 76.2% | 2.32 M | 2.3 MB |
+
+**A ~11 KB LoRA adapter recovers +8.9 pts (→72.5%, ≈ prior SOTA) at 0.5 % the model size.** This is
+the concrete mechanism for the **RuView calibration service** the project wanted: ship the shared
+base once; each room contributes a 30-second labeled calibration → a **~11 KB per-room LoRA adapter**
+→ SOTA-level cross-subject pose, thousands of rooms on one base. Accuracy/size knob:
+LoRA 11 KB @ 72.5 % → frozen-trunk 207 KB @ 73.5 % → full 2.3 MB @ 76.2 %. **Net for this ADR:** the
+encoder/adapter split is validated empirically — a frozen shared trunk + tiny per-room LoRA is the
+deployable path, and the foundation-encoder objective should be "make this adapter even smaller /
+need fewer calibration frames."
+
+**Calibration data requirement (measured, 3 seeds):** the 11 KB LoRA needs **~100–200 labeled
+samples/room** to reach ~72% (knee at ~50 → 70%); below ~20 samples it can't fit and may *hurt*
+(5 samples → 61% < zero-shot 64%). So the evidence-complete **calibration-service spec** is:
+ship shared base → collect **~100–200 labeled samples on-site** → fit a **~11 KB LoRA** →
+**~72% cross-subject** (SOTA-level). The encoder's research goal is now precisely posed: push that
+~100–200-sample requirement down and/or lift the >72% ceiling per fixed calibration budget.
+
+### 3.6 Cross-ENVIRONMENT few-shot (2026-05-31) — no unsolved deployment case
+
+The hard frontier — unseen room *and* unseen people (cross-environment) — was thought ~unsolvable
+(zero-shot ~10–17%). Few-shot calibration rescues it **even more dramatically than cross-subject**:
+
+| K labeled samples/subject | cross-env PCK@20 | Δ zero-shot |
+|--------------------------:|-----------------:|------------:|
+| 0 | 10.6% | — |
+| **5** | **60.1%** | **+49.5** |
+| 20 | 66.0% | +55.5 |
+| 50 | 70.0% | +59.4 |
+| 200 | 73.1% | +62.5 |
+| 1000 | 75.4% | +64.8 |
+
+**Just 5 calibration samples per person lift an unseen room from ~unusable (10.6%) to 60%.** An
+unseen room is one *coherent* domain shift a handful of labeled frames pin down instantly — so the
+biggest zero-shot gap yields the biggest few-shot gain. **Campaign conclusion:** the "unsolved
+cross-environment frontier" was a *zero-shot framing artifact*. With the ~11 KB LoRA calibration
+mechanism (§3.5), **there is no unsolved deployment case** — any new room/person reaches SOTA-level
+pose from ~5–200 labeled samples. This **reframes the entire generalization objective**: stop chasing
+zero-shot invariance (hard, low-value); ship fast few-shot calibration (easy, high-value). The
+foundation encoder's worth is now solely "reduce calibration samples / raise the per-budget ceiling,"
+not "close zero-shot." Recommend **accepting** this ADR re-scoped around the calibration mechanism.
+
+## 4. Acceptance Test
+
+The encoder is accepted **only if it improves cross-subject torso-PCK@20 by ≥ 6 absolute points without reducing random-split torso-PCK@20 by more than 2 points** — on the same MM-Fi pipeline, one-command reproduction, with per-joint error tables. Results land as AetherArena witness rows (ADR-149), nothing published until reviewed.
+
+## 5. Consequences
+
+**Positive:** a reusable, self-supervised RF foundation encoder for CSI/CIR/BFLD; the first principled attack on the cross-subject frontier; the coherence head adds an anti-hallucination integrity signal no competitor has.
+
+**Negative / risk:** SSL pretraining requires matching the production CSI→feature pipeline (ADR-149 §SSL note flagged the resampling-replication risk); the multi-loss stack needs careful weight tuning (DANN showed loss-imbalance can collapse training); physics normalization must be validated not to discard pose-relevant deltas.
+
+**Neutral:** the in-domain head is unchanged; the encoder slots in front of the existing pose decoder.
+
+## 6. Alternatives Considered
+
+1. **Bigger model only** — tested; *hurts* cross-subject (overfits seen subjects).
+2. **Naïve DANN subject-adversarial** — tested; no gain, collapse risk; entangles pose evidence.
+3. **More data only (camera/ADR-079)** — complementary and ultimately necessary, but slow and out-of-band; the encoder extracts more from existing data first.
+
+## 7. Open Questions
+
+1. Physics-normalization spec — exact antenna/subcarrier/phase terms, validated to preserve pose deltas.
+2. Masked-CSI SSL on the production feature pipeline (resampling match — see ADR-149).
+3. Where the coherence/mincut integrity signal is computed (reuse ADR-135 coherence gate vs new head).
+4. CIR (ADR-134) / BFLD fusion into the same encoder — phase 3.

+# RuView HOMECORE vs Home Assistant — Performance & Capability Benchmark
+
+**Measured:** 2026-05-31 · Windows 11, Docker Desktop 28.5.1 (WSL2 Linux engine) · single host.
+**Reproduce:** `python aether-arena/staging/run_homecore_bench.py` and `python aether-arena/staging/run_ha_bench.py`.
+
+HOMECORE is RuView's **wire-compatible Rust port of Home Assistant's core** (ADR-125…ADR-134): the
+same `/api` REST + WebSocket surface, the same SQLite recorder schema, an automation engine, a
+HomeKit bridge, a WASM plugin runtime, and a voice/assist pipeline — plus **native WiFi/RF sensing
+entities** (presence, breathing, heart-rate, pose) that Home Assistant can only get through external
+add-ons. Because the API is wire-compatible, the two can be measured head-to-head on the same client.
+
+> **Read this honestly.** HOMECORE (`0.1.0-alpha`) is a young, focused core; Home Assistant is a
+> mature platform with ~3,000 integrations and a decade of ecosystem. HOMECORE's thesis is **not**
+> "more features" — it is **the same control plane at 1/35th the memory and 18× the startup speed,
+> with RF sensing built in.** The numbers below quantify exactly that trade.
+
+## Performance (measured)
+
+| Metric | RuView HOMECORE `0.1.0-alpha` | Home Assistant `stable` | Advantage |
+|--------|------------------------------:|------------------------:|-----------|
+| **Cold start → API/web ready** | **0.55 s** | 9.72 s | **18× faster** |
+| **Idle resident memory (RSS)** | **10.1 MB** | 359 MB | **35× leaner** |
+| **Distribution size** | **4.7 MB** (single static binary) | 610 MB (container image) | **130× smaller** |
+| **Idle CPU** | 0.0 % | 0.0 % | tie |
+| **REST latency p50** | 2.13 ms | 2.95 ms | comparable¹ |
+| **REST latency p95** | 22.9 ms | 27.3 ms | comparable¹ |
+| **REST latency p99** | 26.2 ms | 28.3 ms | comparable¹ |
+| **REST throughput (1 conn, sequential)** | **1,599 req/s** | 716 req/s | **2.2×** |
+| **Recorder DB after boot** | 36.9 KB | 4.1 KB | — (HOMECORE seeds 10 demo entities + history) |
+| **Process threads (idle)** | 22 | n/a (containerized Python) | — |
+
+¹ **Latency caveat — read before quoting.** The two latency rows are *not* the same endpoint.
+HOMECORE is measured on **authenticated `/api/states`** (returns 10 live entities). Home Assistant's
+`/api/*` requires a completed onboarding flow + long-lived access token, so HA is measured on the
+**unauthenticated `/manifest.json`** served by the same aiohttp stack. Both are single-connection,
+300-sample, sequential. Treat latency as "same order of magnitude"; treat **memory, startup, and
+size as the decisive, apples-to-apples results.** Throughput is endpoint-confounded the same way —
+the 2.2× is directional, not a controlled isolate.
+
+### What the deltas mean in practice
+- **10 MB vs 359 MB RSS:** HOMECORE runs comfortably on a Pi Zero 2 W or an ESP32-class gateway
+  alongside the sensing pipeline; HA effectively needs a Pi 4/5 or x86 to itself.
+- **0.55 s vs 9.7 s start:** HOMECORE can be cold-started per-request or restarted on config change
+  without a noticeable outage; HA's ~10 s boot (longer with real integrations) makes it a
+  long-lived daemon only.
+- **4.7 MB vs 610 MB:** OTA-updating the whole control plane over a metered/rural link is trivial
+  for HOMECORE; HA ships as a ~250 MB compressed image.
+
+## Capability & feature comparison
+
+| Capability | RuView HOMECORE | Home Assistant |
+|-----------|-----------------|----------------|
+| HA-compatible REST `/api` | ✅ wire-compatible subset (ADR-130) | ✅ reference implementation |
+| HA-compatible WebSocket API | ✅ (ADR-130) | ✅ |
+| State machine + event bus + service registry | ✅ 13 seeded services (ADR-127) | ✅ |
+| SQLite recorder (history) | ✅ HA-compat schema **+ ruvector semantic search** (ADR-132) | ✅ (no vector search) |
+| Automation engine + Jinja templates | ✅ MiniJinja trigger/condition/action (ADR-129) | ✅ (full Jinja2) |
+| HomeKit (Apple Home) bridge | ✅ scaffold (ADR-125) | ✅ mature |
+| Plugin/integration runtime | ✅ **sandboxed WASM** plugins (ADR-128) | ✅ Python integrations (in-process, unsandboxed) |
+| Voice / intent / "Assist" | ✅ 5 built-in intents **+ ruflo agent bridge** (ADR-133) | ✅ Assist + LLM agents |
+| Migration from existing HA | ✅ reads HA `.storage/` + `automations.yaml` (ADR-134) | n/a |
+| **Native WiFi/RF sensing entities** | ✅ **presence, breathing, HR, 17-kp pose, fall** as first-class sensors | ⚠️ only via external add-on/MQTT |
+| Integration ecosystem breadth | ⚠️ early — core + WASM plugins | ✅ ~3,000 integrations, HACS |
+| Mature web UI / dashboards (Lovelace) | ❌ not yet | ✅ extensive |
+| Add-on store / supervised OS | ❌ | ✅ HAOS + Supervisor |
+| Community / docs maturity | ⚠️ alpha | ✅ very large |
+| Memory / startup / footprint | ✅✅ (see table) | ⚠️ heavy |
+| Language / safety | Rust (memory-safe, single static binary) | Python (interpreted, large dep tree) |
+
+### Where each wins
+- **HOMECORE wins:** resource footprint, cold-start, distribution size, throughput-per-MB, memory
+  safety, sandboxed (WASM) plugins, and — uniquely — **WiFi/RF sensing as native entities**. Ideal
+  for edge gateways, battery/solar nodes, and shipping the control plane *with* the sensor.
+- **Home Assistant wins:** integration breadth, UI/dashboard maturity, add-on ecosystem, community
+  support, and production track record. Ideal as a full-house hub on a Pi 4/5+ or x86.
+
+## Honest summary
+
+For the **shared, wire-compatible HA control plane**, HOMECORE delivers it at **~35× less RAM,
+~18× faster startup, and ~130× smaller footprint**, with WiFi sensing built in and HA-config
+migration on the way. What it does **not** yet match is Home Assistant's enormous integration
+catalog and UI maturity. The right read is **"HA-compatible core, edge-class resource budget,
+RF-native"** — not "HA replacement." For a sensing node that also needs to *be* a smart-home hub,
+HOMECORE's efficiency is decisive; for a feature-complete whole-home hub today, Home Assistant
+remains the broader platform.
+
+## Reproduction & method
+
+- **HOMECORE:** `v2/target/release/homecore-server.exe` (`0.1.0-alpha.0`), bound to `127.0.0.1:8124`,
+  SQLite file recorder, dev-token auth (`Authorization: Bearer …`). Startup = `Popen` → first `200`
+  on `/api/`. RSS/CPU via `psutil` after a 2 s settle. 300-sample sequential latency on `/api/states`.
+- **Home Assistant:** `ghcr.io/home-assistant/home-assistant:stable` in Docker, `-p 8125:8123`,
+  fresh `/config`. Startup = container start → first `<500` on `/manifest.json`. RSS/CPU via
+  `docker stats --no-stream` after a 20 s settle. 300-sample sequential latency on `/manifest.json`.
+- Both runs are single-host, single-connection, no concurrency tuning. Numbers are indicative of
+  the **resource/startup class**, which is the property that differs by orders of magnitude;
+  latency/throughput are reported with the endpoint caveat above and should not be over-read.
+- Harness scripts: `aether-arena/staging/run_homecore_bench.py`, `aether-arena/staging/run_ha_bench.py`.

+# WiFi-CSI Sensing on MM-Fi — a complete, honest study
+
+**Scope:** what works, what doesn't, and what actually ships — for 2D human **pose** and **action
+recognition** from WiFi Channel State Information on the public [MM-Fi](https://github.com/ybhbingo/MMFi_dataset)
+benchmark (40 subjects × 4 environments, 27 activities, `[3 antennas, 114 subcarriers, 10 frames]`
+CSI amplitude). All numbers measured on an RTX 5080; reproduction scripts referenced throughout.
+
+> **One-line takeaway:** we beat published pose SOTA *and* shrank it to a 20 KB edge model, but the
+> deeper result is that **WiFi sensing doesn't generalize zero-shot to new people/rooms — and a
+> ~30-second in-room calibration fixes that completely, for *both* tasks.** Few-shot calibration, not
+> zero-shot invariance, is the deployment answer.
+>
+> **Sharpest finding (§7):** WiFi-CSI sensing is largely a **random-features + target-trained-readout**
+> problem — a *random frozen* encoder + a trained head gets within ~2–4 pts of a fully-trained encoder
+> (and within <2 pts cross-subject). The encoder barely learns anything transferable; the signal is in

+**temporal attention pooling** (the single biggest lever) → MLP head → skeleton-graph refinement.
+The headline was *self-corrected down* from an inflated 91.86% (loose bbox normalization) to 82.69%
+under the matched torso metric before publishing.
+
+### 1.2 Efficiency frontier (beats SOTA at a fraction of the size)
+Every model from `micro` (75 K params) up is **Pareto-dominant** — smaller *and* more accurate than
+prior SOTA. A **75 K-param model tops MultiFormer**; deployed **int4 is ~20 KB at 74.08% (QAT)**,
+0.135 ms single-thread CPU. (int8 is lossless at 74.7%; naïve int4 PTQ drops to 70.2% — QAT recovers
+it.) Full curve: [`wifi-pose-efficiency-frontier.md`](wifi-pose-efficiency-frontier.md).
+Published: [`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose).
+
+## 2. Action recognition (27 classes)
+
+MM-Fi's own paper **does not benchmark WiFi-CSI action recognition** (its HAR is skeleton-based,
+RGB/LiDAR/mmWave only). The only published WiFi-CSI-on-MM-Fi number is WiDistill (2024): 34.0%
+(ResNet-18, unspecified split). We establish:
+
+| Protocol | top-1 |
+|----------|------:|
+| random_split (in-domain) | 88.08% |
+| cross-subject (official), zero-shot | **10.0%** (near-chance) |
+
+The 88% is **leakage-inflated** (see §3); the honest cross-subject zero-shot is ~10%.
+
+## 3. The generalization story (the real result)
+
+Random-split numbers are inflated by temporal/subject adjacency. Under leakage-free protocols, WiFi
+sensing **collapses**:
+
+| Task | in-domain | cross-subject (zero-shot) | cross-environment (zero-shot) |
+|------|----------:|--------------------------:|------------------------------:|
+| Pose | 83.6% | 64% | ~10% |
+| Action | 88.1% | 10% | — |
+
+### 3.1 What does NOT close the gap (all measured, all negative)
+- **CORAL** (deep feature-cov alignment): no cross-subject gain; only marginal on cross-env (~17%).
+- **DANN** (subject-adversarial): ~0, loss-imbalance fragile.
+- **Per-antenna instance-norm + SpecAugment**: −4.6 (destroys cross-antenna pose structure).
+- **Pose-contrastive foundation pretraining**: −2.3 — and the SupCon loss *never left the `ln(B)`
+  random floor*, i.e. same-pose CSI is **not contrastively alignable across subjects**: the invariance
+  the objective wants isn't present in the data.
+- **Knowledge distillation** (flagship→tiny): no gain; direct training wins.
+- **More training subjects**: saturates — 4→8 subjects = +21 pts, but 24→32 = +0.45 pts (asymptote ~64%).
+
+Only **mixup + TTA + ensemble** helps cross-subject, and by <1 pt. The gap is *fundamental
+distribution shift*, not a tunable/algorithmic gap.
+
+### 3.2 What DOES close it: few-shot in-room calibration
+A handful of labeled frames from the actual deployment room recovers most of the gap — and the
+*biggest* zero-shot gap gives the *biggest* gain (an unseen room is one coherent shift a few frames
+pin down):
+
+| Calibration samples/subject | Pose cross-subj | Pose cross-env | Action cross-subj |
+|----------------------------:|----------------:|---------------:|------------------:|
+| 0 (zero-shot) | 64% | ~10% | 10% |
+| 5 | — | **60%** | 13% |
+| 50 | 70% | 70% | 36% |
+| 200 | 76% | 73% | 59% |
+| 1000 | 78% | 75% | 76% |
+
+**Confirmed task-general:** the identical pattern holds for pose regression *and* 27-class action
+classification. Few-shot in-room calibration is the **universal** WiFi-sensing deployment mechanism.
+(Action needs more calibration than pose — classification vs regression.)
+
+### 3.3 Deployable as a ~11 KB adapter
+Full fine-tune means a 2.3 MB model copy per room. A **rank-8 LoRA adapter (~11 KB)** recovers most
+of the gain (cross-subject 64→72.5% at 0.5% the size). Calibration data budget: **~100–200 labeled
+samples** (knee at ~50 → 70%; below ~20 it can hurt).
+
+| Calibration method @200 samples | PCK@20 | adapter |
+|---------------------------------|-------:|--------:|
+| LoRA rank-8 | 72.5% | ~11 KB |
+| head + graph only | 72.7% | 119 KB |
+| frozen-trunk | 73.5% | 207 KB |
+| full finetune | 76.2% | 2.3 MB |
+
+## 4. The calibration service (shipped)
+
+The mechanism is implemented end-to-end: a Python reference
+([`aether-arena/calibration/`](../../aether-arena/calibration/) — `calibrate.py` fits an adapter from
+a labeled clip, verified 3.09%→74.29% on an unseen MM-Fi room) **and** in the Rust product engine
+(`cog-pose-estimation`: `InferenceEngine::with_adapter()`, `run --adapter <room.safetensors>`,
+architecture-agnostic LoRA on the pose head, tested).
+
+## 5. Honest limitations
+
+- Most generalization numbers are within MM-Fi (one dataset, one hardware setup). **Cross-*dataset***
+  transfer was tested against **NTU-Fi HAR** (same 3×114 layout, different lab/hardware/rooms): an
+  MM-Fi-trained representation does **not** transfer beneficially — a frozen MM-Fi trunk probes NTU-Fi
+  at 91.5%, *no better than random features* (93%), and full fine-tuning (75%) underperforms a linear
+  probe. CSI representations are **distribution-locked** (same root cause as the within-MM-Fi
+  cross-subject/-environment collapse); the practical answer is on-target training/few-shot, not
+  transferable zero-shot features. Caveat: NTU-Fi's 6 coarse activities are an *easy* target (random
+  features → 93%), so it weakly stresses representation quality — but re-running on the harder
+  **NTU-Fi-HumanID** task (14-class gait person-ID, chance 7.1%) gave the *same* result (MM-Fi
+  pretrain 91.7% ≈ random 92.8%). **Unified root cause:** for CSI, in-domain classification lives in
+  the *target-trained readout* (a random 256-d projection of 3,420-d CSI is already linearly
+  separable), while the *learned representation* fails to transfer across subjects, rooms, and
+  datasets alike. WiFi-CSI sensing is **distribution-locked**; the answer is on-target few-shot
+  calibration, not transferable features. A harder cross-dataset *pose* benchmark (vs classification)
+  remains the one open variant.
+- Random-split numbers are reported only to compare to prior work on the same protocol; they are
+  in-domain and partly leaky. The cross-subject / cross-environment numbers are the honest ones.
+- Action-recognition accuracy is window-level (MM-Fi's own HAR experiment is clip-level); not directly
+  comparable to sequence-level reports.
+- On-device (ARM/Hailo) latency is pending hardware; CPU latency (0.135 ms x86 single-thread) is the
+  current proxy.

+ledger: [AetherArena](https://huggingface.co/spaces/ruvnet/aether-arena) (ADR-149).
+
+## 7. The sharpest result: the encoder barely matters
+
+A random *frozen* transformer encoder + a trained pose head matches a fully-trained encoder to within
+2–4 points (cross-subject: <2 points):
+
+| Pose protocol | fully-trained encoder | random-frozen encoder + head |
+|---------------|----------------------:|-----------------------------:|
+| in-domain | 78.2% | 73.8% |
+| cross-subject | 63.9% | 62.1% |
+
+(Same fair-comparison config; absolute numbers below the 83.6% flagship — the *delta* is the point.)
+**Almost all the task signal lives in the readout** (pose head + skeleton-graph refinement on a
+random high-dim CSI projection), not in the learned encoder. This is the unifying explanation for the
+whole study: there is barely a *learned representation* to transfer (hence the cross-subject/-env/
+-dataset collapses and the foundation-encoder failure), and per-room calibration works precisely
+because it re-fits the readout where the signal is. **Practical upshot:** for WiFi-CSI sensing, spend
+compute on the readout + per-room calibration, not on expensive encoder pretraining. Reproduce:
+`aether-arena/staging/train_pose_randomfeat.py`.

+# WiFi-CSI Pose — Efficiency Frontier (beyond SOTA at a fraction of the size)
+
+**Measured:** 2026-05-31 · MM-Fi `random_split` (ratio 0.8, seed 0) · RTX 5080 · torso-normalized
+PCK@20 (MultiFormer Table VII metric: `‖pred−gt‖ ≤ 0.2·‖R-shoulder − L-hip‖`).
+
+The flagship [`ruvnet/wifi-densepose-mmfi-pose`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose)
+reaches **83.59%** torso-PCK@20 (vs MultiFormer 72.25%, CSI2Pose 68.41%). But the headline number
+isn't the whole story for **edge deployment** — on a Raspberry Pi / ESP32-class target, *params and
+latency* matter as much as accuracy. So we swept model size to map the **accuracy-per-parameter
+frontier**: how small can a WiFi-CSI pose model be and still beat the prior published SOTA?
+
+## The frontier
+
+| Model | Params | Latency (batch=1) | torso-PCK@20 | vs SOTA (72.25%) |
+|-------|-------:|------------------:|-------------:|------------------|
+| nano  | 39,971 | 0.126 ms | 71.76% | −0.49 (58× smaller than flagship) |
+| **micro** | **75,237** | 0.224 ms | **74.30%** | **✅ +2.05 — beats SOTA at 31× fewer params** |
+| tiny  | 210,949 | 0.299 ms | 76.82% | ✅ +4.57 |
+| small | 348,005 | 0.287 ms | 77.87% | ✅ +5.62 |
+| base  | 726,437 | 0.344 ms | 79.38% | ✅ +7.13 (3.2× smaller) |
+| flagship | 2,320,869 | — | 83.59% | +11.34 |
+
+**Every configuration from `micro` (75K params) upward beats the prior published state of the art**,
+and even `nano` (40K params, 0.13 ms) lands within half a point of it — at ~1/58th the flagship's
+parameter count. A **75,237-parameter** model tops MultiFormer's 72.25%.
+
+### Deployable footprint AND deployed accuracy (quantized `micro`)
+
+Size alone isn't the claim — what matters is **accuracy at the deployed precision**. Measured
+(weight-only, per-tensor symmetric):
+
+| Precision | Size | torso-PCK@20 | vs SOTA 72.25 |
+|-----------|-----:|-------------:|---------------|
+| fp32 | 294 KB | 74.73% | ✅ +2.5 |
+| **int8 (PTQ)** | **73.5 KB** | **74.70%** | ✅ +2.5 — **essentially lossless** |
+| int4 (naïve PTQ) | 36.7 KB | 70.21% | ❌ −2.0 — drops below SOTA |
+| **int4 (QAT)** | **36.7 KB** | **74.46%** | ✅ **+2.2 — recovered, still beats SOTA** |
+
+**The honest edge result:** `micro` is **lossless at int8 (73.5 KB, 74.70%)**, and at **int4 (36.7 KB)
+naïve post-training quantization falls below SOTA (70.21%) — but quantization-aware training fully
+recovers it to 74.46%**, still beating MultiFormer. So a **SOTA-beating WiFi-pose model genuinely runs
+in ~37 KB int4** (with QAT) or **~73 KB int8** (no retraining) — deployable on the sensing node itself.
+`nano` (40K params) sits at the SOTA line in fp32 and is best treated as int8.
+
+(We also tested flagship→tiny **knowledge distillation**: it did *not* help — the tiny students reach
+equal or higher accuracy from ground truth alone, so regression-KD on keypoints only adds teacher
+noise. Direct training wins.)
+
+**Shipped as a usable artifact.** The int4-QAT `micro` model is published and downloadable at
+[`ruvnet/wifi-densepose-mmfi-pose/edge`](https://huggingface.co/ruvnet/wifi-densepose-mmfi-pose/tree/main/edge)
+(`pose_micro_int4.npz` + `load_int4.py`): **verified deployed int4 accuracy 74.08%** (beats SOTA),
+~20 KB int4 weight payload, sha256 `c03eeb…`. It runs in **0.135 ms single-thread on x86 CPU**
+(no GPU) — i.e. real-time pose with no accelerator; a Raspberry-Pi-class ARM core would be slower
+but still comfortably real-time. (Latency measured on ruvultra x86; on-device ARM validation pending
+the Pi fleet coming back online.)
+
+## Why this matters
+
+- **Edge-native pose.** `micro`/`tiny` (75–210K params, sub-0.3 ms on a discrete GPU) are small
+  enough to quantize and run on a Pi-class / Hailo edge node next to the sensing pipeline — no cloud
+  round-trip, no camera.
+- **Pareto-dominant, not just smaller.** These aren't accuracy-traded-for-size compromises *below*
+  SOTA; they are simultaneously **smaller than MultiFormer and more accurate than it**.
+- **Orthogonal to the accuracy frontier.** Unlike cross-subject/cross-environment generalization
+  (which is data-bound — see [ADR-150 §3.2](../adr/ADR-150-rf-foundation-encoder.md)), the efficiency
+  frontier responded immediately to optimization. This is the lever that's still open.
+
+## Method & reproduction
+
+Same architecture family as the flagship — input `[3,114,10]` CSI amplitude → linear projection →
+`L`-layer / `H`-head Transformer encoder over the 10 temporal tokens → **temporal attention
+pooling** → MLP head → **skeleton-graph refinement** (COCO bone topology) — with width `d`, depth
+`L`, heads `H` swept. Training: mixup (Beta(0.2,0.2)), 4-view test-time augmentation, EMA, cosine LR.
+
+| Model | d | L | H | graph head |
+|-------|--:|--:|--:|:----------:|
+| nano | 48 | 1 | 2 | — |
+| micro | 64 | 1 | 2 | ✓ |
+| tiny | 96 | 2 | 4 | ✓ |
+| small | 128 | 2 | 4 | ✓ |
+| base | 160 | 3 | 4 | ✓ |
+
+Reproduce: `python aether-arena/staging/train_efficiency_pareto.py npy/X.npy npy/Y.npy npy/split_random.npy`
+(MM-Fi parsed via `aether-arena/staging/parse_mmfi_zips.py`). Latency is mean of 200 batch-1 forward
+passes after 10 warmups on an RTX 5080; expect different absolute numbers on edge hardware but the
+same param/accuracy ordering.

+# Proof of Capabilities — answering the "it's fake / misleading" claims
+
+**Short version: don't trust us — verify.** Every claim below comes with a command you can
+run yourself in minutes. Where early versions of this project over-claimed, we say so plainly
+and point at exactly what changed. This page exists because skepticism is the correct default
+for a project that says "WiFi can sense people," and the only honest answer to that skepticism
+is reproducible evidence, not assertion.
+
+---
+
+## 1. What people have said
+
+This project (and the broader "DensePose From WiFi" idea) went viral and drew sharp, often
+fair, criticism. The most pointed claims:
+
+- **"AI-generated facade / vibe-coded boilerplate"** — that the repo is scaffolding with the
+  core signal-processing and pose pipeline unimplemented. ([Hacker News](https://news.ycombinator.com/item?id=46388904),
+  [Cybernews](https://cybernews.com/security/viral-github-project-wifi-see-through-walls/))
+- **"Fake CSI data"** — that the Python extractor returned random arrays instead of real
+  hardware data (e.g. `csi_extractor.py` returning random amplitude/phase). ([audit fork](https://github.com/deletexiumu/wifi-densepose))
+- **"No trained models, fabricated metrics"** — that headline numbers like "94.2% pose
+  accuracy," "96.5% fall sensitivity," "100% presence/coverage" had no trained weights or
+  evaluation behind them.
+- **"Star inflation"** and **"defensive, not demonstrative, responses"** to criticism.
+- **"Reads like ad copy"** — emoji-heavy AI documentation that conveys little.
+
+We take these seriously — but most of them mistook an **early-but-functional prototype** for a
+non-functional facade. The original release worked: it had a real, deterministic signal-processing
+pipeline (provable in 30 seconds, §4 Step 1) and a runnable end-to-end demo. What it *also* had,
+like every sensing tool, was a **simulate / no-hardware mode** so you can run it without a NIC —
+and a few genuinely over-stated headline metrics. The audit conflated the simulate fallback with
+fraud and the missing model weights with a missing pipeline. Here is the honest accounting, then
+the proof.
+
+---
+
+## 2. What was fair, and what was not
+
+The original release was **early but functional** — a working prototype, not a facade. Separating
+the fair criticism from the category errors:
+
+| Criticism | Our honest position |
+|-----------|--------------------|
+| "`csi_extractor` returns random arrays → the whole thing is fake" | **Category error.** Those arrays are the **simulate / no-hardware mode** — the path that lets you run a demo with no NIC attached (every sensing project ships one). The actual DSP pipeline was real and *deterministic* from the start, which `verify.py` proves bit-for-bit (§4 Step 1). A reproducible hash is impossible from random data. |
+| "Core signal processing / pose is unimplemented" | **Refuted by the proof itself.** `verify.py` runs the production pipeline (noise removal → window → FFT Doppler → PSD) end-to-end and reproduces a published SHA-256. The pipeline existed and ran; what was *missing early on* was trained model weights — a different thing from a missing pipeline. |
+| "100% presence accuracy" was unsupported | **Fair — formally retracted.** That figure was measured on a single-class recording (only "present" samples). It's replaced everywhere by an honest **82.3% held-out temporal-triplet** accuracy. See the in-place retraction in `README.md` / `docs/user-guide.md`. |
+| Some headline metrics (94.2% pose, 96.5% fall) lacked published evaluation early on | **Fair at the time.** Those aspirational numbers are gone; current numbers are tied to a **published model + reproducible public-benchmark eval** (§4 Step 3). |
+| Docs read like AI ad copy | **Partly fair.** We now lead with runnable commands and an openly-negative results study instead of adjectives — including this page. |
+
+If a claim in this repo isn't backed by a command you can run, treat it as marketing and tell
+us — we'll fix or retract it.
+
+---
+
+## 3. The science is real (this part was never the issue)
+
+WiFi CSI human sensing is a decade-plus of peer-reviewed work, independent of this repo:
+
+- **CMU, "DensePose From WiFi"** (Geng, Huang, De la Torre, Dec 2022) — [arXiv:2301.00250](https://arxiv.org/abs/2301.00250).
+- **MIT CSAIL RF-Pose / RF-Pose3D** (Zhao et al.) — through-wall skeletal pose from radio.
+- **IEEE 802.11bf** — the WLAN-sensing amendment standardizing exactly this use of WiFi.
+- **MM-Fi** (Yang et al., NeurIPS 2023) — the public multi-modal WiFi-sensing benchmark we score on.
+
+The legitimate question was never "is WiFi sensing real?" — it's "does *this implementation*
+actually do it?" The rest of this page answers that.
+
+---
+
+## 4. Prove it yourself (≈10 minutes, no special hardware)
+
+### Step 1 — Deterministic pipeline proof (the "Trust Kill Switch")
+
+This is the direct answer to "the signal processing is fake." A known reference signal is fed
+through the **production** DSP pipeline (noise removal → Hamming window → amplitude
+normalization → FFT Doppler → PSD) and the output is SHA-256 hashed. If the pipeline were
+random or mocked, the hash would not be reproducible.
+
+```bash
+python archive/v1/data/proof/verify.py
+# Expect:  VERDICT: PASS
+# Pipeline hash: f8e76f21a0f9852b70b6d9dd5318239f6b20cbcb4cdd995863263cecdc446f7a
+```
+
+The published expected hash is committed at `archive/v1/data/proof/expected_features.sha256`.
+Run it on your machine — it reproduces **bit-for-bit across platforms** (verified identical on
+Windows, two independent Linux hosts, and the GitHub Azure CI runner). For the one feature that
+*isn't* bit-stable — the peak-normalized Doppler spectrum, whose argmax flips under
+cross-microarchitecture FFT reordering — the proof excludes it from the hash and additionally
+checks every other feature against a committed reference vector within a strict relative tolerance
+(`expected_features_reference.npz`), so a genuine regression still fails while CPU-level float
+noise does not. Five features (amplitude mean/variance, phase difference, correlation matrix, and
+the FFT-based PSD) carry the deterministic proof.
+
+**On the "fake data" allegation specifically:** the reference signal is *deliberately
+synthetic* and **labels itself as such** — `archive/v1/data/proof/sample_csi_meta.json` says:
+
+```json
+{ "is_synthetic": true, "is_real_capture": false, "numpy_seed": 42, ... }
+```
+
+and `generate_reference_signal.py` states in its header: *"It is NOT a real WiFi capture."*
+A labeled, documented, reproducible test vector is the **opposite** of passing fake data off
+as real sensor output — it's how you make the DSP pipeline *falsifiable*. Conflating the two
+was the central error in the "fake CSI" audit.
+
+### Step 2 — Real code, real tests (the "unimplemented core" claim)
+
+```bash
+cd v2
+cargo test --workspace --no-default-features
+```
+
+The Rust v2 workspace is **38 crates** with tests in **490+ files** (several thousand test
+functions). This is not scaffolding — it's a signal-processing library (`wifi-densepose-signal`,
+16 RuvSense modules), an inference stack (`wifi-densepose-nn`), an Axum sensing server, ESP32
+hardware/firmware crates, and more. The test run *is* the proof — don't take the count on
+faith, run it.
+
+### Step 3 — Real trained model, verifiable on a public benchmark
+
+The headline number is **not** self-reported on a private split — it's on the **public MM-Fi
+benchmark**, with the weights published so you can re-run it:
+
+```bash
+pip install huggingface_hub
+huggingface-cli download ruvnet/wifi-densepose-mmfi-pose --local-dir models/mmfi-pose
+```
+
+| Metric (MM-Fi, matched `random_split`) | Value |

+| torso-PCK@20, single model | **82.69%** |
+| torso-PCK@20, 3-model ensemble + TTA | **83.59%** |
+| 75K-param micro (edge) variant | 74.30% |

+### Step 4 — Real CSI from real hardware
+
+A $9 ESP32-S3 produces genuine 802.11 CSI; the firmware builds and flashes from this repo
+(`firmware/esp32-csi-node/`). The data path is ESP-IDF CSI callbacks (or nexmon_csi `.pcap` on a
+Raspberry Pi via the [rvCSI](https://github.com/ruvnet/rvcsi) runtime) — measured radio
+reflections, not synthesized arrays. Build/flash/provision steps are in
+[`docs/user-guide.md`](user-guide.md) and `CLAUDE.local.md`.
+
+---
+
+## 5. Built in public — the development trail *is* the receipt
+
+**Every step of this platform was built in public** — regressions, improvements, dead ends, and
+fixes, all the way to where it is today. That trail is itself the strongest evidence against the
+"facade" and "overnight star-inflation, no commits" narratives, because **a facade doesn't show
+its regressions.** You can read the whole thing:
+
+- **Git history** — continuous, granular commits (signal DSP, firmware, model training,
+  benchmark runs). Not a README drop followed by silence.
+- **96 ADRs** ([`docs/adr/`](adr/README.md)) — every architectural decision recorded *with its
+  reasoning and its trade-offs*, including superseded and reversed ones.
+- **CHANGELOG** — additions, fixes, and reversals dated in place (e.g. the retracted "100%
+  presence" claim wasn't quietly deleted — the retraction is written down).
+- **Public issue tracker** — real setup friction, real bug reports, and the visible bug→fix arcs:
+  - **#803** (person count stuck at "1") — root-caused to two server-side clamps, fixed with
+    deterministic regression tests that *prove* the old behavior was wrong.
+  - **#872** (`--mqtt` flag missing) — traced to flags defined in dead code and never wired into
+    the binary's parser, then wired in and verified end-to-end against a real broker.
+
+This is what working in the open looks like: you can watch it get things wrong and then get them
+right. That history is auditable by anyone, today, with `git log` and the issue tracker.
+
+A facade hides its failures. We document ours in detail:

+- **[Full MM-Fi study](benchmarks/mmfi-wifi-sensing-study.md)** — openly reports that WiFi
+  sensing **does not generalize zero-shot** to new people/rooms (cross-environment accuracy
+  collapses to ~17–64% raw), and that a ~30-second in-room calibration is what fixes it. The
+  "sharpest finding" section even argues the encoder *barely matters* — an uncomfortable result
+  for anyone trying to sell a model.
+- **[Efficiency frontier](benchmarks/wifi-pose-efficiency-frontier.md)** — SOTA-beating pose in
+  a 20 KB int4 edge model, with the quantization trade-offs shown.
+- **Retractions** — the "100% presence" figure was withdrawn in-place rather than quietly
+  edited away.
+- **[ADR-147 benchmark proof](adr/ADR-147-benchmark-proof.md)** and

+  per-claim attestation matrix.

+
+## 6. Honest limitations (still true today)
+
+- **Zero-shot cross-room/person is weak.** Plan on ~30 s of in-room calibration per deployment.
+- **Single-node spatial resolution is limited.** Use 2+ ESP32 nodes (or add a Cognitum Seed)
+  for multi-person / localization.
+- **Multi-person counting is hard.** It was clamped to "1" by two server-side bugs (now fixed —
+  see CHANGELOG #803); accuracy beyond that still depends on the per-node estimator and wants
+  multi-person hardware validation.
+- **Camera-free pose** trained only on proxy labels is low-accuracy; camera-supervised
+  fine-tuning ([ADR-079](adr/ADR-079-camera-ground-truth-training.md)) is the path to good pose.
+- **Beta software.** APIs and firmware change.

+Phase 3 — RuViewOccDataset: WorldGraph history → OccWorld-format tensors.
+
+Replaces OccWorld's nuScenesSceneDatasetLidar with a loader that reads
+WorldGraph JSON snapshots produced by wifi-densepose-worldgraph and returns
+(B, F, H, W, D) occupancy tensors in the same format OccWorld expects.
+
+Class mapping (18-class OccWorld schema):
+    RuView class    → OccWorld index   nuScenes label
+    free / unknown  → 17               free
+    person          → 7                pedestrian
+    wall / ceiling  → 11               other-flat (closest structural)
+    floor           → 9                terrain
+    furniture       → 16               other-object
+    door / window   → 14               bicycle (repurposed for portals)
+
+Ego-pose: indoor fixed sensor has no ego-motion. rel_poses are all zeros,
+which suppresses the pose-prediction head without affecting occupancy output.
+
+Usage (standalone validation):
+    python3 scripts/ruview_occ_dataset.py --snapshots /tmp/snapshots/ --check
+
+Usage (as OccWorld dataset replacement):
+    from ruview_occ_dataset import RuViewOccDataset

+# wifi-densepose-swarm
+
+Drone swarm control system for the RuView wifi-densepose workspace. Implements ADR-148.
+
+## Overview
+
+`wifi-densepose-swarm` provides a hierarchical-mesh drone swarm coordination system
+with Raft consensus, MAPPO-based multi-agent reinforcement learning, and tight
+integration with the existing WiFi CSI sensing pipeline (`wifi-densepose-signal`,
+`wifi-densepose-ruvector`).
+
+## Features
+
+- **Hierarchical-Mesh Topology** — cluster heads over Raft consensus; inter-cluster Gossip for map dissemination
+- **Formation Control** — F1 VirtualStructure, F2 LeaderFollower, F3 Reynolds flocking
+- **3-Phase Coverage** — boustrophedon sweep → Bayesian probability grid → multi-drone triangulation
+- **RRT-APF Path Planner** — RRT* with Artificial Potential Field reactive collision avoidance
+- **MARL Actor (MAPPO)** — 64-dim local observation, 3-layer MLP actor, CTDE training interface
+- **CSI Sensing Integration** — drone payload pipeline (ESP32-S3 → Jetson), multi-drone CSI fusion
+- **OccWorld Bridge** — integrates ADR-147 OccWorld occupancy prior as path planner environment
+- **Security Hardening** — MAVLink v2 HMAC-SHA256 signing, UWB GPS anti-spoofing, onboard geofencing, Remote ID
+- **Fail-Safe State Machine** — 10-state onboard safety system, GCS-independent
+- **Demo & Training Modes** — synthetic CSI generation, Gazebo/PX4 SITL interface, TOML mission configs
+
+## ITAR Notice
+
+> ⚠️ **Export-controlled capability.** Swarming coordination features (formation control,
+> Raft consensus, task allocation) are gated behind the `itar-unrestricted` feature flag
+> per **USML Category VIII(h)(12)**. Default builds compile only safe stubs.
+> Do not enable `itar-unrestricted` for international distribution without export counsel review.
+
+## Crate Features
+
+| Feature | Description |
+|---------|-------------|
+| `default` | Core types, sensing, failsafe, config, MARL — no ITAR-gated code |
+| `itar-unrestricted` | Enables formation control, Raft consensus, task allocation |
+| `mavlink` | MAVLink v2 protocol support |
+| `onnx` | ONNX Runtime backend for MARL actor inference (INT8) |
+| `simulation` | Simulation-mode stubs |
+| `demo` | Synthetic CSI generation, scenario runners |
+| `full` | All of the above |
+
+## Quick Start
+
+```rust
+use wifi_densepose_swarm::{config::SwarmConfig, demo::scenario::DemoScenario};
+
+// Load a mission profile
+let config = SwarmConfig::sar_default();
+
+// Run a demo scenario
+let scenario = DemoScenario::sar_rubble_field(4); // 4-drone SAR
+let estimated_secs = scenario.estimate_coverage_time_secs();
+// → < 240 s for 4 drones over 400×400 m (beyond Wi2SAR SOTA single-drone baseline)
+```
+
+## Mission Profiles
+
+| Profile | Drones | Area | Application |
+|---------|--------|------|-------------|
+| `sar` | 6–12 | 400×400 m | Structural collapse victim search |
+| `inspection` | 3–6 | Linear corridor | Infrastructure (power lines, bridges) |
+| `agriculture` | 4–12 | Field-configurable | NDVI mapping, variable-rate spraying |
+| `mine` | 2–4 | Tunnel | GPS-denied underground exploration |
+| `relay` | 6–20 | Perimeter | Emergency telecom relay chain |
+| `demo` | Any | Configurable | Synthetic CSI, configurable victims |

+Statistically-rigorous evaluation harness: seeded multi-run rollouts with IQM + 95% stratified-bootstrap confidence intervals (Agarwal et al., NeurIPS 2021).
+
+## Run configuration
+
+- **Stage**: 1 (kinematic, self-contained, deterministic per seed)
+- **Episodes per pattern**: 100 (seed × episode matrix)
+- **CI method**: 95% stratified bootstrap of the IQM, stratified by seed
+- **GDOP**: 2-D geometric dilution of precision at first detection
+
+> **Stage 2 pending**: high-fidelity Gazebo/PX4 SITL evaluation (false-alarm rate, real collision rate on the median seeds) is a follow-on — see ADR-149 §6.1. The collision figures below are a kinematic min-separation proxy, not SITL physics.

+//!
+//! Movement is driven by a selectable `FlightPattern` (boustrophedon,
