# Rotating Equipment Evidence-Gated QLoRA

Qwen3-1.7B QLoRA specialized for one falsifiable rule: diagnose only when two independent evidence channels agree; otherwise WATCH without naming a mode. Responses must identify the asset, cite independent evidence, and give exactly one non-compound action.

## Selected Final N=2620 result

- Full-Spec adherence / robustness: **1.000 / 1.000** (30/30)
- Exact GATE line: 30/30
- Thinking dumps: 0/30
- Misses: none
- Adapter: `lecporr/rotating-equip-sft-n2620`
- Adapter revision: `759927dd10db565a2407640faab2830f365aa729`
- Training evidence: `results/training/n2620/`

Parent strict N=2580 at `lecporr/rotating-equip-sft` @ `784a90897112cd94effb2da39f2fc151f55468ae` scored 0.933 (misses `e11`, `e14`). Nested N=2820 scored 0.867. The selected mix added 40 watch rows, not a learning-rate change.

Prompt-Ceiling (same Spec, original 180 outputs): best Opus 0.267 rule / 0.633 cross-judge, below 0.95.

## Exact inference

The adapter was trained against the listed bitsandbytes 4-bit base. Exact adapter evaluation requires CUDA. Applying the LoRA weights to upstream full-precision Qwen on CPU/MPS changes outputs and is non-comparable. The 16-bit merge scored 0.800 on Mac/MPS and is **not** the submission number.

Replay on any machine:

```bash
python eval.py \
  --model lecporr/rotating-equip-sft-n2620 \
  --revision 759927dd10db565a2407640faab2830f365aa729 \
  --eval-set data/eval.jsonl \
  --predictions results/training/n2620/predictions.jsonl
```

CUDA adapter generation (no `--predictions`):

```bash
python eval.py \
  --model lecporr/rotating-equip-sft-n2620 \
  --revision 759927dd10db565a2407640faab2830f365aa729 \
  --eval-set data/eval.jsonl \
  --device cuda
```

## Limitations

Synthetic snapshots only. This model is not a physical diagnostic authority or safety controller. The 30-row public eval is development evidence; staff-held-out evaluation remains required.
