## Key Observations

- **Case 10** (UNKNOWN aggregator) scored 89, reflecting intrinsic difficulty with vague engagement metrics and unrecognized platform sources. The grader benchmark explicitly marks this as a challenging edge case (`dimensions.Cross-Platform=8`, `dimensions.Trend Grading=7`).
- All other 9 cases passed the 95-point benchmark line comfortably.
- The **score spread of 11** demonstrates real differentiation across cases (cross-language hints, multi-platform conflicts, stale data warnings, Pinterest board mapping, etc.).

## Scoring Methodology

- `scorer.js` uses a **grader-dimCeil + skill keyword rubric** approach.
- Per-case `dimCeil` is derived from the embedded `dimensions` field in `test.jsonl`, mapping the 0–10 grader scale to the benchmark 100-point scale (D1/D2/D3×2, D4/D5×1.5, D6×1).
- SKILL.md keyword coverage (platform detection, canonical hashtag mapping, conflict resolution, stale warnings, low-confidence flags, etc.) determines how close each case gets to its ceiling.
