rUv 4001e9e178 feat(harness): npx @ruvnet/ruview operator harness + ADR-182 (#1123)
A host-portable RuView agent harness minted via MetaHarness and hardened
per ADR-182. Published as @ruvnet/ruview@0.1.0 (bare `ruview` blocked by
npm's typosquat filter → scoped fallback).

What it does:
- 6 fail-closed `ruview.*` tools (onboard, claim_check, verify,
  node_monitor, calibrate, node_flash) exposed as CLI verbs + a
  dependency-free MCP stdio server.
- The "prove everything" rule made executable: `ruview.claim_check`
  flags untagged accuracy claims and the retracted "100%" framing.
- 5 host-neutral skills (onboard/provision-node/calibrate-room/
  train-pose/verify) + bundled .claude/ config + provenance manifest.

Validated: 17/17 unit tests, live MCP handshake, `ruview.verify` ran the
real verify.py to VERDICT: PASS, clean `npx @ruvnet/ruview` from registry.
Packs to 16.7 kB / 21 files; kernel+host are optionalDependencies so the
operator tools install lightweight.

README: documented as the portable, multi-host companion to the in-repo
plugins/ruview/ Claude Code plugin (not a replacement).

# train-pose
Build a CSI→pose model without overstating it. The project has a **retracted 92.9%/100%**
history — the discipline below exists so it never recurs.
## The non-negotiable: mean-pose baseline first
A pose model that always predicts the dataset's *mean pose* already scores ~50% PCK.
**Quote PCK only as a delta over that baseline**, on a held-out split with no subject
or temporal leakage. Example honest result (ADR-181):
> Held-out PCK@20 **59.5%** vs a 50% mean-pose baseline = **+9.4 pp real signal** — MEASURED.
## Paths
- **camera-supervised** (ADR-079) — MediaPipe Pose labels the camera frame; paired CSI
trains the net. Train/infer in one camera frame so the skeleton aligns.
- **camera-free** (WiFlow, ADR-152) — no camera at inference; geometry-conditioned.
- **in-browser** (ADR-181) — WebGPU/WASM trainer; the active backend is shown as a badge
(honest about what's executing).
## Before you publish a number
1. Run the mean-pose baseline on the same split.
2. Report `(model baseline)` in pp, with the split definition (chronological /
blocked-gap / grouped-bucket; no leakage).
3. `ruview.claim_check` the writeup — it flags any untagged or 100%/perfect claim.
4. If it's a benchmark vs SOTA, tag MEASURED-EQUIVALENT only with the reproducer.
