+# ORena FOCUS 2026 — SEGMENT supplementary annotations (public half)
+
+Supplementary VQA annotations produced by **MLO-Lab** for the ORena FOCUS 2026 SEGMENT
+track. This is the openly releasable half; the LapChole-FOCUS half is withheld under that
+dataset's usage agreement until the organisers publish it.
+
+| | rows |
+|---|---:|
+| `vqa/heico_derived.jsonl` — HeiCo-FOCUS | 1,300 |
+| `vqa/hernia_mesh.jsonl` — hernia videos | 140 |
+| **total** | **1,440** |
+
+Also included: `raw/hernia_mesh_annotations/` (12 frame-level annotation sheets) and
+`frames/` (2,539 JPEGs, 290 MB).
+
+## Frames
+
+**HeiCo frames are not redistributed.** Every frame is named by its absolute index in the
+source video, so a question's window plus `base_fps` (25.0) determines the filenames from
+your own copy of FOCUS.
+
+**Hernia frames are included** because the videos are not part of FOCUS and cannot be
+obtained otherwise:
+
+* `frames/clips/<video>/frame<NNNNNNN>.jpg` — 2,307 frames the questions refer to.
+  `base_fps` is 1.0, so index *n* is second *n*.
+* `frames/annotated/<video>/<video>__HH-MM-SS.jpg` — 232 frames carrying the sheet
+  annotations.
+
+Every shipped frame lies inside a window that a released annotation covers; no frame outside
+an annotated segment is included.
+
+## Licensing
+
+Not uniform — read before reuse.
+
+* **HeiCo-derived questions** — derivative annotations of HeiCo-FOCUS; the underlying
+  dataset's terms apply.
+* **Hernia frames and questions** — the source videos carry the **standard YouTube licence,
+  not an open licence**. We redistribute annotated frames only, never the video, under a
+  direct agreement with the channel owner, for **non-commercial research use only**.
+  Full provenance with titles and links is in [`SOURCES.md`](SOURCES.md) and
+  `sources.json`.
+
+## Use
+
+Code, schemas and the merge tooling: **https://github.com/MLO-lab/orena_segment**
+
+```bash
+python annotations/fetch.py                 # this repo
+python segment_track/integrate_released_annotations.py \
+    --export sft_export_128 --annotations annotations --n-frames 128
+```
+
+Questions inherit their clip from the matching window in your own official export, so no
+FOCUS frames need redistributing. With this half alone you rebuild 23,294 of the 23,454
+training rows; the remaining 2,014 are the withheld LapChole questions.

+# Hernia video sources
+
+The hernia questions and frames in this release derive from publicly available
+YouTube videos. **These videos carry the standard YouTube licence, not an open**
+**licence.** We redistribute only annotated frames — never the video — under a
+direct agreement with the channel owner, limited to **non-commercial research**.
+
+All 12 videos come from *California Hernia Specialists: Specialty Care for Hernia Repair*.
