# T01: Built ScoreRunner with 5-dimension LLM-as-judge scoring rubric, CLI score subcommand, and realistic 6-moment sample fixture

**Built ScoreRunner with 5-dimension LLM-as-judge scoring rubric, CLI score subcommand, and realistic 6-moment sample fixture**

## What Happened

Created scorer.py with ScoreResult dataclass (5 float dimensions + composite + justifications + elapsed_seconds + error) and ScoreRunner class that sends technique page JSON and source moments to an LLM judge with a detailed scoring rubric. Updated __main__.py with score subcommand (--file, --slug mutually exclusive; --voice-level optional for T02). Created fixtures/sample_moments.json with 6 realistic music production moments including transcript excerpts with specific plugins/settings.

## Verification

All 4 verification commands pass: import check exits 0, --help shows all 3 args, connectivity error exits 1 with URL and no traceback, fixture validates with 6 moments.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd backend && python -c "from pipeline.quality.scorer import ScoreRunner, ScoreResult; print('import ok')"` | 0 | ✅ pass | 1000ms |
| 2 | `cd backend && python -m pipeline.quality score --help` | 0 | ✅ pass | 1000ms |
| 3 | `cd backend && python -m pipeline.quality score --file pipeline/quality/fixtures/sample_moments.json` | 1 | ✅ pass | 3000ms |
| 4 | `cd backend && python -c "import json; d=json.load(open('pipeline/quality/fixtures/sample_moments.json')); assert 'moments' in d and len(d['moments']) >= 5"` | 0 | ✅ pass | 1000ms |
