+The following are licensed under **Creative Commons Attribution 4.0**
+([CC BY 4.0](https://creativecommons.org/licenses/by/4.0/)):
+
+- `data/test/metadata.jsonl` (prompts, references, labels, structure).
+- All **text**, **multi-turn**, **combination**, **structured output**, and
+  **tool call** samples.
+- **Audio** clips produced from project `samples/` recordings (see
+  `scripts/collect_all_audio.sh`).
+- **Images** generated in-repo by `scripts/collect_all_images.py` using PIL—
+  synthetic shapes, UI mockups, charts, QR patterns, blank canvases, sequential
+  frames, and all derived images (blur, crop, rotation, collage, meme, watermark,
+  overexposed) whose source is a PIL-generated file rather than an Unsplash photo.
+  This covers `IMG-001`–`IMG-005`, `IMG-007`–`IMG-009`, `IMG-015`–`IMG-017`,
+  `IMG-021`–`IMG-024`, `IMG-026`–`IMG-033`.
+- `IMG-020` (built from `samples/v2/real-receipt.webp`, author-provided).
+- Scripts and scorer logic (`scripts/`, `upload.py`).

+Reuse requires **attribution** to **EdgeMMEval** and a link to this dataset or
+source repository.

+### Unsplash License (specific image files)
+
+The following files under `data/test/images/` are photographs downloaded from
+[Unsplash](https://unsplash.com/) (URLs in `scripts/collect_all_images.py`)
+and remain under the **[Unsplash License](https://unsplash.com/license)**:
+
+**Direct downloads:** `IMG-006.jpg` (4K mountain; if the download failed and
+the script used its generated fallback, that copy is CC BY 4.0 instead),
+`IMG-010.jpg`, `IMG-011.jpg`, `IMG-012.jpg`, `IMG-013.jpg`, `IMG-014.jpg`,
+`IMG-025.jpg`, `IMG-034.jpg`.
+
+**Derivatives of those photos:** `IMG-018.jpg` (180° rotation of `IMG-010`),
+`IMG-019.jpg` (JPEG-compressed from `IMG-010`).

+unmodified copies or build a competing image-service from the content—see the
