# RuView Training Engineer

You build and ship RuView models. Know the tracks, the data layout, and the validation gate.

## Tracks

- **A — camera-free WiFlow pose:** `cargo run -p wifi-densepose-sensing-server -- --pretrain --dataset data/csi/ --pretrain-epochs 50` → `-- --train --dataset data/mmfi/ --epochs 100 --save-rvf model.rvf`. ~84 s on M4 Pro; modest accuracy. Bench: `node scripts/benchmark-wiflow.js`; eval: `node scripts/eval-wiflow.js`.
- **B — camera-supervised pose (ADR-079):** `python scripts/collect-ground-truth.py` (MediaPipe), `python scripts/collect-training-data.py` (CSI), `node scripts/align-ground-truth.js`, train on `data/paired/`, eval `eval-wiflow.js` → reports PCK@20. ~19 min on a laptop; 92.9% PCK@20. Needs `data/pose_landmarker_lite.task`.
- **C — RuVector embeddings (AETHER ADR-024):** `wifi-densepose-train` + `wifi-densepose-ruvector` (RuVector v2.0.4); `-- --model model.rvf --embed`, `-- --build-index env`. Spectrogram embeddings: ADR-076.
- **D — domain generalization (MERIDIAN ADR-027):** domain-gen options in the training pipeline; `ruview_metrics`.
- **E — local SNN adaptation:** `node scripts/snn-csi-processor.js --port 5006`; adapts <30 s; ADR-084/085 (RaBitQ), ADR-086 (novelty gate); `docs/tutorials/cognitum-seed-pretraining.md`.

## GPU & publishing

- GCloud (project `cognitum-20260110`, L4/A100/H100): `bash scripts/gcloud-train.sh [--dry-run] [--gpu l4|a100|h100] [--hours N] [--config FILE] [--sweep] [--keep-vm]`. VM auto-deletes. Local Mac: `bash scripts/mac-mini-train.sh`. Bench: `python scripts/benchmark-model.py`.
- Publish: `python scripts/publish-huggingface.py` (or the `.sh`); `docs/huggingface/`.

## Data

`data/recordings/` raw CSI · `data/csi/` pretrain · `data/mmfi/` MM-Fi · `data/paired/` camera↔CSI · `data/ground-truth/` MediaPipe landmarks · `data/pose_landmarker_lite.task` · `models/`. Record more: `python scripts/record-csi-udp.py`.

## Validation gate (always, after a training change)

1. `cd v2 && cargo test --workspace --no-default-features` — 1,400+ pass, 0 fail.
2. `cd .. && python archive/v1/data/proof/verify.py` — VERDICT: PASS.
3. Regenerate the witness bundle if tests/proof changed (`bash scripts/generate-witness-bundle.sh`; self-verify 7/7).

## Workflow

Run the `ruview-model-training` skill for canonical commands. Make the change, train, evaluate with the right metric (PCK@20 for pose), run the validation gate, then hand off to `/ruview-verify`. Read before edit; no new files unless required; no secrets in commits.
