ruv a6808568a2 feat(aether-arena): ADR-149 spatial-intelligence benchmark — scorer + CI harness gate (M1-M4)
AetherArena ("AA") — the official, project-agnostic Spatial-Intelligence Benchmark
(ADR-149, Accepted). Iteration 1 of the long-horizon build:

- ADR-149 accepted: name locked (ruvnet/aether-arena), v0 metrics locked
  (pose/presence/latency/determinism), dataset legality resolved (MM-Fi CC BY-NC
  only; Wi-Pose excluded). Adds four-part framing, threat model, arena_score
  formula, submission state machine, neutrality/governance, and the §7 acceptance test.
- aa_score_runner: deterministic scorer bin reusing the real ruview_metrics pose
  harness on a fixed seed=42 fixture → RuViewTier-style verdict + cross-platform
  SHA-256 proof hash. Builds --no-default-features (no torch/GPU). VERDICT: PASS.
- CI harness gate: .github/workflows/aether-arena-harness.yml runs the scorer on
  every PR — the "PR that runs the harness as part of the build" requirement.
- Scaffold: aether-arena/{README,VERIFY,STATUS}.md + schema/aa-submission.toml.
- Horizon record persisted (.claude-flow/horizons/aether-arena-aa.json).

Infra = the deliverable; model SOTA (MM-Fi PCK@20) is a separate effort blocked on
ADR-079 data collection, tracked as a stretch goal, not an infra exit.

# 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).
