<strong>PhotoBench</strong> is the first benchmark constructed from authentic, personal albums, designed to shift the paradigm from visual matching to personalized multi-source intent-driven photo retrieval.
<strong>PhotoBench-Protected</strong> is the limited-information release: only pre-computed captions, embeddings, and metadata are provided, so this leaderboard focuses exclusively on <strong>agent planning</strong> ability.

<p style="margin-top:16px; color:#7CB342; font-weight:600;">
⚠️ Please confirm you are submitting to the correct leaderboard.

SUBMISSION_GUIDE = """
### Submission Format

The dataset provides `test.json` per album. You must **combine all albums into a single JSON array** and add the `album_id` field to each query before submitting.

**Example transformation:**

```python
import json

submission = []
for album_id in ["1", "2", "3"]:
    with open(f"protected/album{album_id}/test.json") as f:
        queries = json.load(f)
    for q in queries:
        submission.append({
            "album_id": album_id,
            "query_en": q["query_en"],
            "pred": ["IMG_0001.jpg", "IMG_0002.jpg", ...]  # your predictions
        })

with open("submission.json", "w") as f:
    json.dump(submission, f, indent=2)
```

**Final submission format:**

```json
[
  {
    "album_id": "1",
    "query_en": "cluttered desk",
    "pred": ["IMG_1234.jpg", "IMG_5678.jpg", ...]
  }
]
```

**Required fields:**
- `album_id`: Album number (`"1"`, `"2"`, or `"3"` — string)
- `query_en`: The English query text (must match exactly, case-sensitive)
- `pred`: Ordered list of predicted image filenames (order matters for NDCG)

You may submit results for any subset of albums. Partial submissions are accepted and evaluated, but **only full submissions** (all 3 albums, all test queries) are eligible for public leaderboard ranking.
"""

EVALUATION_INFO = """
### Evaluation Metrics

| Metric | Description |
|--------|-------------|
| **Recall@k** | Proportion of ground-truth images found in top-k predictions |
| **NDCG@k** | Normalized Discounted Cumulative Gain at rank k |

Supported k values: **1, 5, 10, 20, 50, 100**

Results are averaged across all evaluated queries per album, then averaged across albums for the final leaderboard score.
