ruv 483bfa4660 feat(aether-arena): benchmark-first scorer + witness chain + repeatability (M2/M5/M7)
Per direction "remove the initial number, optimize for benchmark first" + "include
witness chain capabilities for proof and repeatability analysis":

- Empty board, no seeded numbers: ledger seeds to genesis only. Every result is a
  real scoring-pipeline witness; RuView gets no hand-entered baseline.
- Real model scoring: aa_score_runner now loads predictions + an eval split
  (--split/--pred) and scores them through the real ruview_metrics pose harness —
  not just a synthetic fixture. Committed public smoke split (fixtures/smoke_*.json).
- Witness chain: each score emits a witness = inputs_sha256 (binds it to the exact
  inputs) + proof_sha256 (cross-platform-stable score hash) + harness_version.
- Repeatability analysis: --repeat N runs the harness N× and fails if it ever
  yields >=2 distinct proof hashes (16/16 identical locally).
- Witness ledger: ledger/ledger_tools.py — append-only, hash-chained, tamper-
  evident (seed/append/verify); editing any past row breaks the chain.
- CI gate extended: determinism + repeatability(16) + real-scoring smoke + ledger
  chain verify on every PR.

# AetherArena — Build Status
Tracks ADR-149 implementation milestones. "Complete" = benchmark **infrastructure** done,
tested, CI-gated, deploy-ready, RuView baseline entered, §7 acceptance test passing.
Model **SOTA** (e.g. MM-Fi PCK@20 ~72%) is a separate long-running ML effort, blocked on
ADR-079 camera-ground-truth collection — *not* an infra-completion blocker.
| # | Milestone | Status |
|---|-----------|--------|
| M1 | ADR-149 Accepted + committed | ✅ done |
| M2 | Scorer runner (`aa_score_runner`) — **real model scoring** + witness (proof+inputs hash) + **repeatability analysis** | ✅ done — builds `--no-default-features`, determinism gate PASS, repeatable 16/16 |
| M3 | CI harness-gate workflow (PR runs scorer + repeatability + real-scoring smoke + ledger verify) | ✅ done — `.github/workflows/aether-arena-harness.yml` |
| M4 | Scaffold: README + submission schema + VERIFY (acceptance test) | ✅ done |
| M5 | Public smoke split (committed) + private MM-Fi held-out split prep | 🟡 smoke split done (`fixtures/smoke_*.json`); private MM-Fi prep pending |
| M6 | HF Space (Gradio) submission flow + sandboxed scorer container | ⏳ token located (GCP secrets); Space app next |
| M7 | **Witness ledger chain** — append-only, hash-chained, tamper-evident | ✅ done — `ledger/ledger_tools.py` (seed/append/verify); tamper test fails as designed |
| M8 | Public launch | ⏳ — **board starts EMPTY; no seeded numbers** (benchmark-first: only real harness scores) |
## Benchmark-first posture (per user direction)
- **No placeholder numbers on the board.** The ledger seeds to genesis only; every result is a real scoring-pipeline witness. RuView gets no seeded baseline.
- **Witness chain** = `inputs_sha256` (binds witness to exact inputs) + `proof_sha256` (cross-platform-stable score hash) + the append-only hash-chained ledger. Repeatability analysis (`--repeat N`) proves the proof hash is identical across runs.
## 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.
- **Private MM-Fi split (M5)** — needs the dataset pulled + a held-out split assembled before real public scoring replaces the smoke fixture.
